The planet '''Earth''', third from the [[Sun]] in the [[Solar System]] in the [[Milky Way]] galaxy, is a world populated by a wide variety of native organic lifeforms, including [[human]]s. Versions of this planet are known to exist in many dimensions within the multiverse, and for some strange reason, it frequently becomes involved in the conflicts of the [[Transformer]]s. Perhaps ''too'' frequently. Whenever someone or something leaves, escapes, or is otherwise ejected from [[Cybertron (planet)|Cybertron]], there's a disproportionate chance it will eventually wind up on Earth, as opposed to, say, any of the other planets in the vast universe. Earth is orbited by one satellite, which its inhabitants have uncreatively dubbed "the [[Moon (moon)|Moon]]."

Earth is superficially similar to the planet upon which [[you]] may reside, but has many subtle and not-so-subtle differences.

In some universes, Earth's connection to Cybertron is furthered by being the resting place of a Transformer deity, as [[Primus]] resides within Cybertron, such as [[Gaea]], [[Atlas (G1)|Atlas]], or even the dreaded [[Unicron/Aligned|Unicron]].

In [[Beast Wars II: Super Lifeform Transformers (cartoon)|some universes]], Earth becomes the post-apocalyptic planet '''[[Gaia]]'''.

Even before the arrival of the Transformers, Earth had evidently been visited by another race of aliens; by four million years ago, however, the only trace of their presence was the [[Savage Land]]: a hidden jungle in [[Antarctica]] where [[dinosaur (dinosaur)|dinosaurs]] still lived. {{storylink|Repeat Performance!}} Around this time, the ''[[Ark (G1)|Ark]]'' crashed into Earth, and remained there until the present day. {{storylink|The Transformers (issue)|The Transformers}}

The [[human]] known as [[Jesus]] was supposedly born over 2000 years ago, and his birth would eventually lead to the holiday called [[Christmas]]. {{storylink|Stargazing}}

In the year [[1017]] AD, the Autobot [[Navigator (Autobot)|Navigator]] and his companion arrived on Earth in search of the lost ''Ark''. Their ship landed near the town of [[Stansham]], [[United Kingdom|England]]; every few centuries, his companion would scout out the surface. His first appearance turned the tide of a great battle, and the awed residence of [[Stansham]] would dub him the "[[Man of Iron (Autobot)|Man of Iron]]." {{storylink|Man of Iron (issue)|Man of Iron}}

[[File:ActionForce Groupshot.jpg|thumb|right|250px|A typical example of mid-80s military forces.]]

In the 18th century, pirates roamed the seas filling up their treasure chests. [[Raindance|Two]] [[Grand Slam (G1)|Autobots]] were sent to Earth at this time, but were seemingly rendered offline in the process; they were found and then lost by a crew of pirates. {{storylink|Club Con!}}

The outbreak of the [[Korean War]] in the 1950s saw the [[United States of America]] embroiled in the conflict, with [[Sparkplug Witwicky|Irving Witwicky]] serving with the [[United States Marine Corps]] during the war. {{storylink|The Last Stand}}

By the 1980s, Earth was involved in a [[Cold War (history)|Cold War]] driven by the United States of America and the [[Soviet Union]]. The planet was also threatened by the international terrorist group [[Cobra]], who was opposed by either America's [[G.I. Joe (team)|G.I. Joe]] organisation {{storylink|Blood on the Tracks}} and/or the international [[Action Force (team)|Action Force]] {{storylink|Ancient Relics!}} ([[The Transformers (Marvel comic)#Marvel US|sources]] [[The Transformers (Marvel comic)#Marvel UK|disagree]]). There also existed a group called [[S.H.I.E.L.D.]], an American spy organisation that primarily handled the monstrous [[Godzilla]], and otherwise seemed to have little prominence. {{storylink|Prisoner of War!}}

[[File:Spider-man.jpg|thumb|left|250px|Marvel's lawyers would prefer it if you ignored this.]]

By a quirk of genetics, the [[Neo-Knights|odd human]] proved capable of wielding superpowers. {{storylink|The Human Factor!}} The earliest known was a vigilante named [[Spider-Man]] who vanished after 1984 for unknown reasons, though he did clash with the Decepticons {{storylink|Prisoner of War!}} causing Megatron to rethink how dangerous humans were. {{storylink|The Enemy Within!}}

The Autobot and Decepticon war would rage until [[1991]] before a brief lull; both sides would relocate their bases to multiple locations, and while often battling in America they would also strike in the United Kingdom, [[Peru]], [[Canada]], [[Mexico]], [[Japan]], and Argentina. Responsibility for dealing with them in the States fell to the [[Intelligence and Information Institute]], yet another American spy group (the 1980s was clearly a paranoid and unstable time), and their military wing [[Rapid Anti-robot Assault Team|RAAT]]. Diplomatic relations ''were'' tried early on with the [[President of the United States]], but failed.

{{Earthforcefiction}}
In [[Primax 290.03 Gamma|an alternate timeline]], the bulk of the Autobot/Decepticon war moved off-world in [[1990]] and a small [[Earthforce]] remained, containing two duelling Decepticon factions {{storylink|Break-Away!}} (who later united). {{storylink|Internal Affairs!}} The Autobot base was located in [[Canada]], where an abnormally high number of [[polar bear]]s roam the wilderness; the animals have even become bold enough to approach the Autobot base. {{storylink|Front Line! (issue)|Front Line!}}

=====Marvel UK future timelines=====
In several alternate timelines where Unicron attacked in [[2006]], the Autobots were allowed to build a city on Earth, which would become a major location for scattered Autobots to regroup after Decepticon conquest of Cybertron. Diplomatic relations were strong between human and Autobot, and futuristic technology such as weather-control machines were gifted to mankind. {{storylink|Ark Duty}} Many centuries later, Earth had become a second home for the Autobots, and in the year [[2356]] a decrepit [[Hot Rod (G1)/Marvel Comics continuity|Rodimus Prime]] had taken up permanent residence in the city. {{storylink|Aspects of Evil!}}

====="Rhythms of Darkness"=====
[[File:Nyc-alternate-future1.jpg|thumb|left|250px]]
In yet [[Primax 490.0 Gamma|another timeline]], the Americas were brutally conquered after 2005 by [[Galvatron II|Galvatron]]. In response, the continent of [[Europe]] united under a European Crisis Coalition. {{storylink|Rhythms of Darkness!}} Following the disappearance of [[Galvatron II|this universe's version of Galvatron]], however, the people of Earth were able to stage a successful uprising against their Decepticon conquerors, and the [[Human Confederacy|Confederation of Terran Worlds]] was born. In time, the Confederation would grow to include the inhabitants of the similarly liberated planet [[Nebulos]], and, would eventually, form an alliance with [[Jhiaxus (G2)|Jhiaxus]]'s [[Cybertronian (faction)|Cybertronian Empire]]. {{storylink|Ask Vector Prime#Facebook|Ask Vector Prime, 2015/06/24}}

====''Transformers Comic-Magazin''====
Evidence in ancient [[Egypt]] suggested that the planet had been visited by Autobots in the past, with records depicting a mysterious being known only as "Imus" supposedly aiding in the construction of the [[Great Pyramid of Giza]]. [[Bumblebee (G1)/Marvel Comics continuity|Goldbug]] theorized that this might have been a temporally-displaced [[Optimus Prime (G1)/Marvel Comics continuity|Optimus Prime]]. {{storylink|Transformers Comic-Magazin issue 18|The Curse of the Pyramids}}

Early into their conflict on modern Earth, the Autobots were instrumental in preventing the Decepticons from stealing [[oil]] from various human industries, {{storylink|Transformers Comic-Magazin issue 2|Attack at Dawn}} {{storylink|Transformers Comic-Magazin issue 3|Damaged Ship on The High Sea}} {{storylink|Transformers Comic-Magazin issue 5|The Invasion Of The Decepticons}} though some Autobots, like [[Slapdash (G1)|Slapdash]], held the opinion that Earth would be better off under a one-world Autobot government. {{storylink|Transformers Comic-Magazin issue 6|A Big Day for Powermaster Optimus Prime}}

Perhaps because of this sentiment, Decepticon leader Megatron would try to trick the citizens of Earth into believing that the Decepticons had given up their warlike ways, though his peace offering of a "statue" was soon revealed as a clever ruse. {{storylink|Transformers Comic-Magazin issue 4|The Troy Principle}} Megatron would briefly hold the entire Earth hostage, demanding the planet's entire arsenal of weaponry be delivered to the Decepticons before the Autobots foiled his plan by stealing back his hijacked nuclear missiles. {{storylink|Transformers Comic-Magazin issue 8|Megatron's Ultimatum}} A dimensional portal once opened on Earth, which briefly connected the planet to, among other places, the [[Andromeda Galaxy|Andromeda nebula]]. {{storylink|Transformers Comic-Magazin issue 9|Headmaster of the Dimensions}}

An Earth-based laser constructed by [[Shockwave (G1)/Marvel Comics continuity|Shockwave]] was powerful enough that it could be seen from Cybertron. {{storylink|Transformers Comic-Magazin issue 19|Shockwave's Galactic Secret}} Some time later, a videotape from Earth somehow wound up in the Cybertronian city of [[Kalis]]. {{storylink|Transformers Comic-Magazin issue 21|In Memory of Earth}} 

In the year [[2008]], [[Hot Rod (G1)/Marvel Comics continuity|Rodimus Prime]] would remember Optimus's adventures on Earth fondly. {{storylink|Transformers Comic-Magazin issue 17|Powermaster Optimus Prime - a Robot, a Hero}}

====Marvel ''Generation 2'' comic====
[[File:Franciscog2.jpg|thumb|right|200px|Ba-THROOOOM!]]
In [[1993]], the Decepticons struck Earth with overwhelming force, devastating cities and slaughtering millions, merely as a way of attracting Autobot attention. Even this was dwarfed when the [[Cybertronian (faction)|Cybertronian]] warlord [[Jhiaxus (G2)|Jhiaxus]] blew up [[San Francisco]] the following year. The long-term impact this had on Earth is unknown.

[[File:Cameos Invasion.jpg|thumb|left|250px]]
: ''See also:'' [[Gaea]]

This particular Earth was home to a reservoir of [[Rarified Energon]], the resource becoming central to the Autobots and Decepticons who warred on the planet. The power of this substance also attracted the attention of the [[Ultra Magnus (SG)|Ultra Magnus]] of [[Primax -408.24 Epsilon]] who invaded [[Primax 207.0 Epsilon]]. Letting the [[Terminus Blade]] interact with the Rarified Energon, Magnus unleashed space/time anomalies that began destroying the universe, while setting up shielding to protect his bounty. [[Soundwave (SG)|Soundwave]] managed to extend the range Magnus's shield to cover the entirety of Earth resulting in the whole planet being dragged into the negative polarity universe. {{storylink|Invasion (issue)|Invasion}}

Detecting this otherworldly intrusion, [[Primus/Shattered Glass|Primus]] moved to attack the world. Before he arrived, all inhabitants were teleported off Earth, which revealed itself to be [[Gaea]]. Once the goddess had defeated Primus, she reformatted herself into a new Cybertron to serve as a new home for Transformers of either faction, while teleporting all the humans to a new planet in another dimension. {{storylink|The Future Buried...}}

The Earth of ''that'' universe was nigh-identical to the Earth its inhabitants had left behind, albeit utterly uninhabited by humans. {{storylink|Assembly (OMAM)|Assembly}} As it turned out, ''this'' Earth was located in a parallel universe where Cybertron had been destroyed during the Great War by the combiner [[Thunder Mayhem]]. {{storylink|Foundation and Wreckage Part 1: Deadly Aim|Deadly Aim}} Five years after humanity's arrival the planet was briefly attacked by both [[Ramjet (Universe)|Ramjet]] and this monstrous combiner, though the Autobots were able to repel the invasion. {{storylink|Finale (OMAM)|Finale}} 

The [[GoBot]]s of an [[Gargent 984.08 Alpha|alternate dimension]] landed on the original Earth, searching for a way to save their own reality from a great [[Cataclysm (GoBots)|Cataclysm]], {{storylink|Sunrise}} and thanks to the efforts of the [[Caretaker]] and [[Small Foot]]'s sacrifice, the team succeeded in their mission. {{storylink|Last Sunset}}

[[File:LooseEndsPart3-boom.jpg|thumb|right|300px|Alright, who farted?]]

After the Ark crashed on Earth for a second time, the crash site was patrolled by [[Spike Witwicky (G1)|Spike Witwicky]] and [[Fortress Maximus (G1)/Marvel Comics continuity|Fortress Maximus]] for two years before Spike called it quits in [[1993]]. Following his retirement, someone, either very greedy or very bored or both, managed to enter the Ark, resulting in [[Megatron (G1)/Marvel Comics continuity|Megatron]] being reactivated. Using his mental connection with [[Ratchet (G1)/Marvel Comics continuity|Ratchet]], the tyrant managed to reactivate the Ark and used the warship's onboard systems to devastate Earth, turning the planet into a nuclear wasteland. {{storylink|Loose Ends, Part 3}} The only known human settlement remaining on the planet's surface was [[Little America]]. {{storylink|Destiny, Part Two}} The only pre-existing structure that was spared destruction was the [[Deep Space Network]] telescope in [[Goldstone]] via which Megatron attempted to contact [[Optimus Prime (G1)/Marvel Comics continuity|Optimus Prime]] for their final battle. {{storylink|Loose Ends, Part 2}}

[[File:LooseEndsPart1-Earth.jpg|thumb|left|300px]]

In [[2012]], the Autobot [[Kup (G1)/Marvel Comics continuity|Kup]] broke ranks to clean up the many loose ends of the Great War leftover on alien planets. The first stop was Earth, but upon arrival, he and the [[Wreckers]] were caught off-guard by the state of the planet and shot down by Megatron. {{storylink|Loose Ends, Part 1}} The Wreckers managed to use the Goldstone telescope to contact Optimus Prime, {{storylink|Loose Ends, Part 2}} before they joined up with the "Little America" humans in an attempt to cripple the Ark and free Earth. {{storylink|Loose Ends, Part 3}} When Optimus Prime finally arrived, he managed to slay Megatron once and for all while Spike Witwicky – now "Circuit Smasher" – managed to overload the Ark's systems and prevent [[Aunty]] from unleashing another salvo of nuclear warheads on Earth. {{storylink|Loose Ends, Part 5}}

After the Autobots had rounded up and vaporized Megatron's [[zombie]] army, they were voted off Earth by the humans. {{storylink|Natural Selection, Part One}} Over the protests of [[Ultra Magnus (G1)/Marvel Comics continuity|Ultra Magnus]], Optimus Prime elected to remain on Earth in an attempt to atone for the mistakes his inaction had wrought to the planet. {{storylink|Natural Selection, Part Two}} He first made his way to the Ark, to try and destroy the mighty vessel, only to arrive in time to see it take off under [[Galvatron II|Galvatron]]'s command. {{storylink|Natural Selection, Part Five}}

[[File:Little america destiny.jpg|thumb|right|300px]]

Optimus contacted Magnus to let him know the Ark was in enemy hands and on-approach to Cybertron with his SIC informing him on developments on [[Nebulos]], which gave Optimus an idea to help the two planets. {{storylink|Destiny, Part One}} After enduring electrical torture at the hands of Circuit Smasher, Optimus Prime was able to present his plan to Little America; linking the Earth and Nebulos via Space Bridge. The humans would bring indomitable resolve, while the [[Nebulan]]s would bring advanced technology, allowing the two worlds to heal together. {{storylink|Destiny, Part Two}}

[[File:WarToEndAllWarsPart5-andthriving.jpg|thumb|left|300px]]

Optimus commenced construction of a Space Bridge in [[Oklahoma]], while a twin was built in the [[Clar Macro-jungle]] on Nebulos, both linked through the [[Star Chamber]]. {{storylink|The War to End All Wars, Part 1}} As part of its plan to ascend to the larger multiverse, the [[Dark Matrix]] sent Fortress Maximus to Earth once the Space Bridge came online to cripple Optimus and abduct Spike. {{storylink|The War to End All Wars, Part 3}} After the Dark Matrix entity had been defeated, Earth and Nebulos would go on to thrive in their partnership. {{storylink|The War to End All Wars, Part 5}}
{{-}}

====''Transformers '84''====
Believing Megatron to be the lynchpin that held the Decepticon army together, Optimus deliberately crewed the ''Ark'' with [[Autobot High Command]] to lure [[Decepticon High Command]] off-planet. When the ''Ark'', after destroying an [[asteroid belt]] that threatened to destroy the rogue Cybertron, was boarded by the Decepticons, Optimus crashed the ship into Earth. {{storylink|Transformers '84 issue 0|'84 #0}}

Observing these events from the ''[[Nemesis (G1)|Nemesis]]'', Shockwave, after disabling the [[Conehead]]s, travelled down to Earth to ensure that there were no loose ends. Discovering instead a primordial world brimming with raw energy and an abundance of resources, Shockwave set up a mining station only to be attacked by the Dinobots, reactivated by the ''Ark''<nowiki>'</nowiki>s systems when he entered the atmosphere. When the Dinobots confronted him, the scientist defeated four of them but was unprepared for Grimlock boosting himself with a capsule of raw energon, burying the Decepticon. {{storylink|Secrets & Lies issue 2|Secrets & Lies #2}}

When the Coneheads recovered, they travelled down to Earth and found the ''Ark'' at roughly the same time as a delirious Grimlock who was fighting off a [[drone]] force that a damaged AUNTIE had deployed. While the Seekers fought the drones, Grimlock faced off against a trio of [[Guardian (Marvel)|Guardians]], burning off his power high, just as Megatron was reactivated. {{storylink|Secrets & Lies issue 3|Secrets & Lies #3}}

To defend herself, AUNTIE activated Megatron's [[antimatter]] abilities, only for Grimlock to stab the tyrant. Lacking Megatron's training with the power, AUNTIE was helpless to prevent it leaking out, the antimatter threatening to destroy the Earth before Grimlock deactivated AUNTIE, saving the planet. The Coneheads meanwhile had retreated to the ''Nemesis'' but found themselves unable to start the ship. In exchange for keeping the location of Earth, and more importantly Megatron, a secret, [[Straxus (G1)|Straxus]] sent a rescue ship. {{storylink|Secrets & Lies issue 4|Secrets & Lies #4}}

The starship ''[[Mantlo]]'' landed on Earth in the year [[1017]] while in search of the ''Ark'', though the Autobot deep-cover agent [[Punch (G1)|Punch]] was forced to doublecross his allies during a skirmish with his Decepticon unit, and sent them crashing into [[Stansham Castle]]. {{storylink|Transformers '84 issue 0|'84 #0}}

===Generation 1 cartoon continuity===
====''The Transformers'' cartoon====
[[File:Kingnergill.jpg|thumb|right|250px|An earthling.]]

Around nine million years ago, the Earth was visited by the Transformers [[Starscream (G1)/Generation 1 cartoon continuity|Starscream]] and [[Jetfire (G1)|Skyfire]], but Skyfire was caught in a polar wind storm and separated from Starscream, buried in ice. {{storylink|Fire in the Sky}} Then, approximately four million years ago, the Transformers' spacecraft, the ''[[Ark (G1)|Ark]]'', crash-landed in what would become the north-western [[United States of America|United States]], entombing the robots within in stasis. {{storylink|More than Meets the Eye, Part 1}} 

Earth is home to many unusual creatures and "hidden civilizations." The underwater city of [[Sub-Atlantica]], populated by water-breathing, fish-like humanoids, gave rise to the legends of [[Atlantis]] and other sunken cities. {{storylink|Atlantis, Arise!}} Fire-breathing [[dragon]]s existed naturally as late as the medieval era, though by the 20th century, they appeared to have died out. {{storylink|A Decepticon Raider in King Arthur's Court (episode)|A Decepticon Raider in King Arthur's Court}} A possible descendant was a [[Beast of Borneo|unique, reptilian creature]] captured by big game hunter [[Chumley|Lord Chumley]] in [[Borneo]]. {{storylink|Prime Target (episode)|Prime Target}} A [[Dinobot Island (G1)|strange, secluded island]] was home to [[Dinosaur (dinosaur)|dinosaur]]s and other prehistoric creatures, thanks to the landmass occupying a strange position in space-time. {{storylink|Dinobot Island, Part 1}} Lurking almost out of sight are the strange, hidden monsters known as [[Inhumanoids]]. {{storylink|Transformers Animated: The AllSpark Almanac II|The Allspark Almanac II: Ask Vector Prime}}

Around the same time as the Transformers, Earth was ravaged by the predations of a [[Cobra|terrorist organisation]] led by the sinister [[Cobra Commander|"Old Snake"]]. Luckily, [[G.I. Joe (team)|some real American heroes]] opposed them and by 2005 they'd be a distant memory. {{storylink|Only Human}}

[[File:Ultimate Doom 3 Cybertron leave.JPG|thumb|left|250px]]

The magma energy of the [[Earth's core]] is channeled by a series of green crystalline structures, which the Decepticons attempted to exploit in 1984, exposing a crystal shaft in the North Pole and tapping the core's energy (while, at the same time, happening upon and reactivating the body of Skyfire). {{storylink|Fire in the Sky}} On another occasion, Earth was imperiled by the arrival of Cybertron in the solar system; due to the gravitational disturbances, the planet was ravaged by earthquakes and storms {{storylink|The Ultimate Doom, Part 2}} until the Autobots were able to knock their homeworld out of Earth's orbit. {{storylink|The Ultimate Doom, Part 3}}

Another unusual aspect of the planet is the natural existence of [[electrum]], a metallic alloy that renders Transformers invulnerable when coated in it. {{storylink|The Golden Lagoon (episode)|The Golden Lagoon}} 

[[File:OnlyHuman New York opening cityscape.jpg|thumb|right|250px]]

By the year 2005, the Autobots had established [[Autobot City (G1)|Autobot City]], a permanent base on Earth. {{storylink|The Transformers: The Movie}} Human interaction with the Transformers had resulted in an advanced level of technology worldwide, and the foundation of the [[Earth Defense Command]], which operated a series of space stations. [[Saturn]]'s moon, [[Titan (moon)|Titan]], was colonised, and an EDC base was established on [[Mars (planet)|Mars]], while travel between star systems was hugely enhanced by the creation of [[warp gate]]s. Earthling [[Spike Witwicky (G1)|Spike Witwicky]] became Earth's ambassador, first to [[Cybertron (planet)|Cybertron]], and then to other alien worlds as, through the Transformers, humanity came into contact with other races. {{storylink|Five Faces of Darkness}}

As part of a truly bonkers scheme in 2007, [[Galvatron (G1)/Generation 1 cartoon continuity|Galvatron]] moved Cybertron back into the solar system and tried to use the [[Plasma Energy Chamber]] to cause Earth's sun to go nova, destroying the organic world and Cybertron. Fortunately, the Autobots managed to have [[Vector Sigma]] absorb the excess solar energy which revitalized Cybertron and left Earth unharmed. {{storylink|The Rebirth, Part 3}}

[[File:RiseUpPretenders-Earth.jpg|thumb|left|250px|Baba yetu, yetu uliye, mbinguni yetu, yetu, amina.]]
At some point, a shard of the universe-creating [[Zodiac]] was entombed in Earth. {{storylink|Enter the New Supreme Commander, Dai Atlas!}} {{Storylink|Legends Comic: Bonus Edition Vol. EX 2 Roadfire Chapter|Roadfire Chapter}} Some time after the [[#Beast Wars cartoon|Beast Wars]], the time-travelling [[Sparkbot]]s attempted to use the [[Angolmois Energy]] they collected to resurrect [[Unicron/Generation 1|Unicron]] on Earth. Their plot was foiled by [[Primus]], who sealed the Angolmois Energy and the Sparkbots within the planet. To guard this dangerous energy, Primus created [[Fortress Maximus (RID)|Brave Maximus]] and set up several safeguards for his activation. {{storylink|Sparkbots Volume 5}}

During the Stone Age, an evil energy being, knowing of both the Angolmois Energy and the Zodiac on Earth, brought stolen [[Powermaster]] bodies from [[G Nebula 89]] to the planet. Using both power sources, the entity created the [[Godmaster (lifeform)|Godmaster]]s from the Powermasters and transformed itself into [[Devil Z]]odiac, falling to slumber afterwards. {{storylink|Legends Comic: Bonus Edition Vol. EX (Grand Maximus)|Bonus Edition Vol. EX}} {{storylink|Shūta and Grand's Masterforce Super-Secrets!}} At around the same time, a small group of [[Autobot]] and [[Decepticon]] [[Pretender]]s crash-landed on the planet. While the Autobots used their Pretender abilities to adopt the form of humans, the Decepticons assumed monstrous forms and were mistaken by early man as "demons." Finally defeating the Decepticons and sealing them away—within the [[pyramid]]s of [[Giza (region)|Giza]], the ruins of [[Atlantis]], and beneath the [[Nazca Lines]] of Peru—the Autobots then integrated themselves into human society, serving as secret protectors who quietly and subtly guided the evolution of human society. {{storylink|Rise Up!! Pretenders}} The planet would receive further visitors, in the form of [[Commando (RID)|a team of second-generation Autobots]] who were sent from the future to activate Brave Maximus to safeguard "Gaia Energy", which they misunderstood Angolmois Energy to be. {{Storylink|Koji Gets His Wish|JRX Versus Baldigus}} {{Storylink|Ruination Chapter, Part One}} However, their ship crashed onto [[Castle Peak|Angel Mountain]], where its passengers slumbered till the end of the 20th century. {{storylink|The Decepticons|Foe? Friend!? Black Convoy}}

In the years immediately preceding the reactivation of the ''Ark'' in [[1985]], a group of [[Micromaster]]s established [[Metrobase (G1)|Metrobase]] as a headquarters to guard the crashed starship until the volcano's eruption, and would be bolstered by the temporally-displaced [[Multiforce]] in their battle against their Decepticon counterparts. {{storylink|The Menace of Landcross's Combining Formation!}}

In [[2000]], Brave Maximus would be uncovered and reactivated by the Autobot [[Dimensional Patrol]] and [[Predacon (BW)|their Predacon counterparts]], both groups which had traveled back in time from the future. {{storylink|Fortress Maximus (episode)|Arise! Cybertron City}} {{storylink|Maximus Emerges|Stolen Plasma}} After the destruction of Unicron in [[2005]], {{Storylink|The Transformers: The Movie}} the defeated [[Galvatron (G1)/Generation 1 cartoon continuity|Galvatron]] crash-landed in [[Tokyo]], destroying the city and spreading his infectious Unicron cells amongst Earth's machines and organic life, creating the [[Legion (KP)|Legion]] and [[Kiss Player]]s. Despite the Autobots' best efforts, the disaster resulted in massive anti-Transformer sentiment and the [[Earth Defense Command]] erected an [[anti-electron]] field that forced all Cybertronians off the planet. Through efforts from native humans and their Autobot partners, the EDC's actions under the misguided [[Hitoshizuku Amaō|Commander Amaō]] were put to a stop, Galvatron and his cells were expelled from the planet, and Transformers were welcomed back to the planet. {{Storylink|Transformers: Kiss Players (franchise)|Kiss Players}}

The following decades would find Earth under threat from the Decepticons, such as from [[Scorponok (G1)|Scorponok]]'s [[Death Tower]]s in [[2011]] {{storylink|The Final Showdown on Earth (Part 2)}} and then by the awakened [[Devil Z]]'s plots to wipe the surface of all life around 2020. {{Storylink|Crisis! The Day of Human Extinction}} {{storylink|A Battle... and Then...}} The citizens of Earth would join forces with the Autobots, and other sentient races across the galaxy, to form the anti-Decepticon [[Galactic Peace Alliance]] before the year [[2025]]. {{storylink|The Brave Hero of the Universe - Star Saber}} Some years later, Earth was attacked by several members of the [[Nine Great Demon Generals]] during the battle for the Zodiac, buried deep beneath the planet's surface, though the Autobots were able to snatch the Zodiac away from their foes at the last minute. {{storylink|Enter the New Supreme Commander, Dai Atlas!}} Angolmois Energy was finally discovered by humanity within Gaia Energy in [[2039]], and it spurred massive advances in human technology. {{storylink|Transformers Legends Final Chapter "Epiloge"|Epiloge}}

By [[2050]], humanity had experienced a quantum surge in technology using their mastery over Angolmois to produce such innovations as the [[Mother Computer]], {{storylink|Abominus comic 1}} the [[Selector]]s and even managing to cure the long-term health problems of Cybertronians. The Selectors however took issue with being enslaved by humanity and revolted with the martial backing of the Decepticons. When Optimus Prime tried to put a halt to the fighting, Megatron pointed out that freedom was the right of all sentient beings and the Selectors were sentient beings. {{storylink|Volcanicus comic 1}} Capitulating, Optimus formally petitioned the humans to grant freedom to the Selectors only to be confronted by the [[Dinobot (G1)|Dinobots]], who chose to side with humanity, and the [[Technobot (G1)|Technobots]], who remained loyal to Grimlock. When a series of events led to Grimlock regaining his super-intelligence, he promised to find a peaceful solution to this conflict. Sadly though, Spike Witwicky had grown desperate enough to seek assistance from the Quintessons, bringing a [[Quintesson Judge|Judge]] to the Mother Computer who told the two creator species to ally. Eagerly, the Judge summoned the [[Terrorcon (G1)|Terrorcons]]. {{storylink|Volcanicus comic 2}}

Cackling madly, the Judge revealed to Spike that the Terrorcons would harness the Angolmois Energy within Earth, allowing the Quintessons to create a second Unicron and use their monster to rule the universe. As more and more Quintesson forces arrived, Megatron began absorbing Angolmois Energy into himself, even as this ran the chance of reawakening his evil nature. Having gotten a first hand reminder of the evil of the Quintessons, Spike defied his would be ally who responded by shooting him. {{storylink|Abominus comic 1}}

With so much evil, the Angolmois Energy began erupting across Earth, corrupting Transformers and indeed turning Megatron evil again. As Spike and the Selector [[Rung (G1)|Rung]] made peace, they defeated the Judge and discussed how to save their homeworld. {{storylink|Abominus comic 2}}

Salvation came when [[Lio Convoy]] used righteous Angolmois Energy to purify Megatron's spark and send it back in time to the [[Precursor World]]. Now aware that Earth was too dangerous a world to remain on, humanity and the Selectors left Earth to make a new home elsewhere in the galaxy. The Cybertronians meanwhile all returned home and erased all records of Earth from their archives. {{storylink|Generations Selects Special Comic Finale Part 2}}

Tens of thousands of years after the Earthlings had left their home, {{storylink|Emissary of the Fourth Planet}} the planet's biosphere had reverted to a pristine, largely unspoiled wilderness. {{storylink|The New Forces Arrive!}} Traces of humanity persisted in scattered ruins, [[Mother Computer|an ancient computer system]] containing information on the planet's prior inhabitants, {{storylink|White Lion, Run!}} and a lunar outpost manned by the androids [[Artemis]] and [[Moon (BW)|Moon]] to ensure that Earth's supply of Angolmois Energy remained unmeddled with. {{storylink|Emissary of the Fourth Planet}} Some [[Copy Machine|discarded technology]] remained operational. {{storylink|The Black Lio Convoy}} 

This version of Earth, known to the Cybertronians of this era as "'''[[Gaia]]'''", was visited by Maximals and Predacons under the respective commands of [[Lio Convoy]] and [[Galvatron (BW)|Galvatron]], {{storylink|The New Forces Arrive!}} and was menaced by the monstrous [[Nemesis (BW)|Nemesis]] before Lio Convoy was able to save the planet. In the process, a large portion of Gaia's Angolmois Energy was sent scattering through space encased in Angolmois Capsules. {{storylink|Farewell! Lio Convoy}}

Several years later, [[Big Convoy]]'s [[Big Convoy Unit|unit]] would visit Gaia to investigate Lio Convoy's disappearance and came across [[Magmatron]] and [[Magmatron Unit|his troops]]. Both sides would discover the existence of Angolmois Capsules and leave Gaia to gather them. {{Storylink|Big Convoy, Move Out}}

====''Wings Universe''====
{{wingsnote}}

From 1984 to 2006, Earth was the primary battleground during the Great War between the Autobots and Decepticons; following the battle on [[Nebulos]], however, the Decepticons retreated to the far reaches of the galaxy, and Prime's inner cadre of Autobots pursued them, leaving only a skeleton crew behind on Earth. 

Around the beginning of the 21st century, the Autobots worked with the Earth Defense Command to increase ties between their peoples. The pooled efforts of human, Cybertronian, and [[Nebulan]] science led to the creation of the first [[cyberfactory|cyberfactories]], leading to a new generation of Earth-born Transformers with the rights of citizens of human nations. Though this "second generation" was created with no faction in mind, by 2010 many had migrated to opposing sides in the Cybertronian civil war, either to U.S. citizen [[Clench (G1)|Clench]]'s [[Decepticon Syndicate]] or to UK citizen [[Pyro (G1)|Pyro]]'s Autobots. {{storylink|Generation 2: Redux}}

In 2013, [[Autobot City (G1)|Autobot City]] on Earth was host to the signing of the [[Pax Cybertronia]]. {{storylink|A Common Foe}}

By the late 30th century C.E., Cybertron no longer had active contact with Earth. [[Apelinq (BM)|Apelinq]] only knew of Earth as a "fabled planet" referenced in Cybertronian texts. {{storylink|Tornado - Decepticon Saboteur|Apelinq's personal logs}}

====Ask Vector Prime====
In [[Primax 1185.04 Alpha|one parallel universe]], the Autobots and Decepticons awoke in 1984 to learn that the evil forces of [[Cobra]] had already conquered the planet. Though the Autobots—disgusted by the callous governments of Earth, and spurred on by Optimus Prime's insistence not to meddle in the affairs of other species—built and launched a starship that would take them off Earth, Megatron stayed behind, hoping to conquer the planet. His war against Cobra was brief and brutal: although bolstered by reinforcements such as the Insecticons and Constructicons, Cobra's [[M.A.S.S. Device]] and the increasingly unethical products of Cobra science pushed Megatron's back against the wall, until, out of desperation, he allied with [[Nergill]] and the forces of Sub-Atlantica.

Even this alliance was not to last; when Cobra stormed the undersea city, the Sub-Atlanticans double-crossed Megatron and were able to paralyze him, trapping the Decepticon leader in his alternate mode. In the aftermath, Starscream seized command of the Decepticons, and the stragglers were quick to evacuate the Earth using Shockwave's [[space bridge]] with whatever scraps of energon they could take with them. {{storylink|Ask Vector Prime|Ask Vector Prime, 06/13/2015}}

Shortly after reawakening in the modern era, Megatron and the [[Constructicon (G1)|Constructicon]]s enacted a scheme to force the people of Earth into surrender by holding visitors to the [[Freedom Sports Arena]] hostage, though this plan was swiftly foiled by the Autobots. {{storylink|Battle for Earth}}

In the distant past, at the height of the [[Great War (G1)|Great War]], the starship ''Ark'' crash-landed on Earth, buried beneath [[Mount St. Hilary]] for millions of years. {{storylink|The Agenda (Part 1)}}

At some point afterwards, the mysterious aliens known as the [[Vok]] selected prehistoric Earth as the site for a long-running experiment, the ultimate end goal of which is still unknown. As part of their machinations, the Vok seeded the young planet with vast amounts of raw [[energon]], {{storylink|Other Voices, Part 1}} erecting mysterious constructions at strategic intervals, such as a [[Brigadoon|floating "island"]] {{storylink|The Trigger, Part 1}} and the [[Standing Stones|standing stones]], designed to attract and study any intelligent lifeforms on the planet. {{storylink|Chain of Command (BW)|Chain of Command}} As a failsafe, the Vok installed an artificial second moon over the planet, a [[Planet Buster|laser weapon]] designed to detonate Earth's volatile energon and sterilize the entire biosphere.

From the distant future, 300 years after the end of the Great War, the [[Predacon (BW)|Predacon]] criminal [[Megatron (BW)/Beast Wars cartoon continuity|Megatron]] was able to steal a [[Golden Disk (Voyager)|Golden Disk]], which contained a hidden message left behind by [[Megatron (G1)|the original Megatron]]. Aware that the recent invention of [[unspace|transwarp]] technology would enable Cybertronians to [[time travel|travel backwards in time]], the Decepticon leader instructed whoever found the message to travel back to prehistoric Earth and kill Optimus Prime while he lay in stasis, changing history and ensuring a Decepticon future. {{storylink|The Agenda (Part 2)}} {{storylink|The Agenda (Part III)}} The ruling council of this era, the [[Maximal High Council]], had declared Earth off-limits; knowledge of the planet, and its sector in space, was tightly regulated. {{storylink|Deep Metal}}

[[File:Protohumans1 CodeofHero.jpg|thumb|right|250px|And scientists cried in frustration.]] 

Though pursued by a group of [[Maximal]]s, Megatron's [[Darksyde (BW)|stolen ship]] and the Maximal vessel ''[[Axalon (BW)|Axalon]]'' crash-landed on Earth; though Megatron initially believed that the planet was ''not'' Earth, due to its too moons, he deigned that the planet's rich supply of Energon would allow him to nonetheless conquer Cybertron. Taking on [[beast mode]]s to protect themselves from [[energon radiation]], the two sides waged a conflict they dubbed the "[[Beast Wars (event)|Beast Wars]]," {{storylink|Beast Wars (Part 1)}} {{storylink|Beast Wars (Part 2)}} and accidentally alerted the Vok to their presence after stumbling into one of their many sites. {{storylink|Chain of Command (BW)|Chain of Command}}

Deciding that the Beast Warriors had contaminated their experiment, the Vok activated the second moon and began their sterilization protocol. {{storylink|Other Voices, Part 1}} This plan was foiled by the Maximal leader, [[Optimus Primal (BW)/Beast Wars cartoon continuity|Optimus Primal]], {{storylink|Other Voices, Part 2}} but the vast majority of the raw Energon on the planet was transformed into stable, cube form. {{storylink|Coming of the Fuzors (Part 2)}} {{storylink|Tangled Web}}

[[File:Waspinatorhappyatlast.jpg|thumb|left|250px|Earliest known human religion.]]

Both factions soon became aware of [[anthropoid|early hominids]]. A foiled Predacon attempt to slaughter them caused them to both disperse and develop knowledge of crude tools and weapons; {{storylink|Code of Hero}} [[Cheetor (BW)|Cheetor]] happily intervened in the natural course of Time by teaching the young hominids simple physics lessons; {{storylink|Go with the Flow}} and after the end of the war, when the victorious Maximals returned to Cybertron, [[Waspinator (BW)|Waspinator]] was left on the planet as the leader and god of a hominid tribe. {{storylink|Nemesis Part 2}} Although they eventually rejected him and he too returned to Cybertron, {{storylink|The Catalyst}} it is unclear precisely how much influence Waspinator may have had on the evolution of humanity and their culture. Many would find this dizzturbing.

[[File:MTMTE-Earth.jpg|thumb|right|250px]]
In a vision from the [[Matrix of Leadership]], both [[Optimus Prime (G1)|Optimus Prime]] and [[Megatron (G1)|Megatron]] had a vision of their future selves battling it out on Earth; {{storylink|The War Within issue 5}} not long afterwards, the ''Ark'' would indeed crash-land on the Earth some four million years ago, and the Autobots remained offline until the modern day. {{storylink|Transformers: The Ultimate Guide}}

Around this time, the [[Dinobot (G1)|Dinobot]]s pursued the [[Insecticon (G1)|Insecticon]]s to the world. Though Grimlock's unit believed that they had killed their foes, the Insecticons had survived, and took their operations underground for millennia. {{storylink|Extermination}} 

In [[1984]], the two dormant factions of Cybertronians reawoke, and hostilities between the two commenced anew in a war for Earth's abundant sources of energy. It would take some time—and the assistance of the [[Witwicky (surname)|Witwicky]] family—before the majority of humanity came to realize that the Autobots were there to protect them, eventually leading to the formation of the [[Earth Defense Command]]. {{storylink|Transformers: More than Meets the Eye}} In the year [[1998]], humans and Autobots were able to conclusively rout the Decepticons and end the Great War in "[[Operation Liberation]]," however, the subsequent launch and destruction of the ''[[Ark II]]'', intended to take the Autobots home seemingly killed Prime and all of his followers. {{storylink|Prime Directive issue 1}} This would be revealed as a massive coverup, however, as the ship had been deliberately sabotaged by General [[Robert Hallo]] in an attempt to capture the Transformers and remake them into military weapons. {{storylink|Prime Directive issue 5}} The Decepticon Shockwave, who had seized control of Cybertron in the interim, ''also'' claimed to have facilitated the destruction of the vessel, seeking to keep the two leaders and their followers safely contained on Earth until the time was right. {{storylink|Revelation (War and Peace)|Revelation}}

[[File:Atonement-warroom.jpg|thumb|left|250px|"On the other hand, gentlemen... what if we had a war and EVERYBODY came?"]]

Though the Transformers would be able to free themselves from human control, the city of [[San Francisco]] was largely destroyed in the crossfire; a year later, (and after another alien invasion by the alien [[Keeper (species)|Keepers]] {{storylink|The Transformers Trilogy}}) Shockwave had, by then, secured his hold over Cybertron, and subsequently turned his sights to Earth, where he arrested all of the Autobots and Decepticons on the planet and sent them to Cybertron for re-education. {{storylink|New World Order}}

After overthrowing Shockwave, groups of Transformers eventually returned to Earth, and the Autobot [[Jetfire (G1)|Jetfire]] sacrificed himself to save the entire planet from the out-of-control threat of a maddened [[Sunstorm (G1)|Sunstorm]], {{storylink|Atonement}}, and the EDC teamed up with the Autobots to deal with the return of the Insecticons. {{storylink|Extermination}} Their two worlds now intertwined, the Autobots began breaking ground on [[Autobot City (G1)|Autobot City]] to house the Autobots currently active on the planet. {{storylink|The Route of All Evil}}

Though many hints were dropped that suggested Earth and Cybertron shared a common history, one that ran much deeper than the inhabitants of either world suspected, the true nature of this connection was never elaborated on. When asked, known liar [[Sideways (ROTF)|Sideways]] claimed the organic world was merely fodder for Decepticon conquest. {{storylink|Ask Vector Prime#Ask Sideways|Ask Sideways, 2015/06/28}}

===''G.I. Joe vs. the Transformers''===
[[File:BlackHorizonPart1-CobraLa.jpg|thumb|right|250px|Is that Cookie Monster?]]
160,000 years ago, Earth was colonized by the ancient civilization known as "[[Cobra-La]]," a humanoid race who supposedly hailed from another world, and wielded strange organic technology. When Earth was visited by [[Unicron/Generation 1|Unicron]] during the zenith of their reign, the people of Cobra-La cut a deal: in exchange for them not deploying their virulent [[Metal-eating spore|metal-eating fungus]] against him, Unicron would depart and return in a few thousand years, when [[human]]ity had grown numerous, and the subsequent apocalypse and enslavement of the human race would leave Earth untouched, so that Cobra-La to rule once more. {{storylink|Black Horizon, Part 1 of 2}} In the 20th century, a Decepticon ship crash-landed atop their hidden city, beneath the [[Himalayas]], and the Decepticons were outfitted with biotechnology after pledging their servitude. {{storylink|Black Horizon, Part 2 of 2}}

In the modern day, the forces of the [[Cobra]] terrorist organization had captured and reprogrammed more Transformers to serve them in their quest for world domination, but provoked a nuclear response from the [[United Nations]]: one powerful enough to potentially jeopardize the entire Earth. {{storylink|G.I. Joe vs. the Transformers issue 5}} 

Two years after the Autobots and the members of the newly minted [[G.I. Joe (team)|G.I. Joe]] had saved the day, Cobra-backed researchers in [[Boston]] opened a wormhole that connected Earth to Cybertron after piggybacking off the Cybertronian supercomputer [[Teletran 3]]—a coincidence orchestrated by Shockwave, who planned to harness the connection to launch a full-scale Decepticon invasion of Earth. Conflict with Cobra caused the network malfunction, hurling various Autobots through time; if they were not retrieved, the temporal feedback would burn the Earth clean of all life. {{storylink|G.I. Joe vs. the Transformers II issue 1|G.I. Joe vs. the Transformers II #1}} 

[[File:BlackHorizonPart2-Unicron.jpg|thumb|left|250px]]

A time-hopping adventure ensued as both Cobra and Joe members travelled through Earth's history; beginning in the mid-1970s, {{storylink|G.I. Joe vs. the Transformers II issue 1|G.I. Joe vs. the Transformers II #1}} then to [[Chicago]] in [[1937]], {{storylink|G.I. Joe vs. the Transformers II issue 2|G.I. Joe vs. the Transformers II #2}} and finally into a potential post-apocalyptic future, where Shockwave's original scheme had come to fruition. {{storylink|G.I. Joe vs. the Transformers II issue 3|G.I. Joe vs. the Transformers II #3}} Though the team managed to foil Shockwave's scheme and avert Earth's destruction, only three months passed before the resurgent inhabitants of Cobra-La began their own plan to summon Unicron with the help of [[Doctor Mindbender]]. {{storylink|G.I. Joe vs. the Transformers II issue 4|G.I. Joe vs. the Transformers II #4}} 

In the meantime, US scientists worked to develop a sentient Earth defense system using Cybertronian technology, but the result was the malevolent [[Serpentor|Serpent O.R.]], {{storylink|The Art of War issue 1|The Art of War #1}} who swiftly launched an attack on Cybertron. {{storylink|The Art of War issue 2|The Art of War #2}} 

By the time of Serpent O.R.'s defeat, Optimus returned to Earth to help purge Cybertronian technology from the planet, unaware that Unicron had begun his approach to the planet. {{storylink|Black Horizon, Part 1 of 2}} As Cobra-La and its Cybertronian allies made themselves known once more to both the Autobots and Joes on Earth, [[Flint (G.I. Joe)|Flint]] and [[Cosmos (G1)|Cosmos]] were able to purloin samples of Cobra-La's original spores and deployed the payload directly into Unicron's brain, destroying him and saving the planet. {{storylink|Black Horizon, Part 2 of 2}}

===''Transformers/G.I. Joe''===
The Transformers had arrived on the planet under unknown circumstances, and a temple on the [[Fera Islands]] had been built around their remains. A dangerous faction known as [[Cobra]], however, would discover them in [[1938]], and so erupted [[World War II]]: Cobra and the Decepticons taking on everyone else, and overrunning Europe. The threat caused the United States to enter the war in [[1939]], creating the world's first modern special forces unit in [[G.I. Joe (team)|G.I. Joe]]. A Joe/Autobot joint operation would end the war by defeating the Decepticons, but at the cost of the Autobots all dying.

In [[1985]], Cobra would resurface as a terrorist organisation. The remains of the Transformers would be used for a massive arms race.

===2005 IDW continuity===
[[File:TheCrucible-TheDawnOfMan.jpg|thumb|right|200px]]

The planet Earth formed some 4.5 billion years ago. {{storylink|Crisis Intervention}} Over the course of its prehistory, various life-forms rose and fell, including [[Dinosaur (dinosaur)|dinosaur]]s; a remnant population of the creatures existed in a secluded jungle at the [[Arctic|North Pole]] well into the modern day. {{storylink|Scarlett's Strike Force issue 2|Scarlett's Strike Force #2}} At some point during Earth's prehistory, an [[Elder God]] and its aquatic servants took up residence in the planet's oceans. {{storylink|Infestation 2: The Transformers issue 1|Infestation 2 #1}}

Roughly seven to eight million years ago, at the conclusion of the [[First Cybertronian Civil War]], the barbarian warrior [[Galvatron (G1)/2005 IDW continuity|Galvatron]] launched the [[Enigma of Combination]] into space, and by pure coincidence this artifact would eventually fall to Earth. {{storylink|The Crucible}}

[[File:SpotlightShockwave-seeding.jpg|thumb|left|250px]]

During the Great War between the [[Autobot]]s and [[Decepticon]]s, the Decepticon scientist [[Shockwave (G1)/2005 IDW continuity|Shockwave]] selected Earth as one of the thirteen worlds for his [[Regenesis]] project, and fired a missile loaded with [[Ore-13]] at the planet some 600,000 years ago. {{storylink|Spotlight: Shockwave}}

Unbeknownst to the younger Shockwave, his time-travelling future self—in the guise of "[[Onyx Prime]]"—had deliberately ensured that his younger self would choose Earth as one of the thirteen planets involved, as the presence of the Enigma ensured that it possessed a connection to the [[Thirteen]]. {{storylink|The Falling, Interlude: The First Who Was Named|The First Who Was Named}} Using supplies of [[Ore-1]], [[Ore-9]], and [[Ore-10]], "Onyx Prime," armed with his foreknowledge of the future, was able to shunt the [[Titan (group)|Titan]] [[Metrotitan (G1)|Metrotitan]] across time and space, eventually burying him beneath [[Monument Valley]] so that [[Optimus Prime (G1)/2005 IDW continuity|Optimus Prime]] would find him. {{storylink|The Falling, Chapter 4: The Hallowing|The Hallowing}}

In the meantime, "Onyx" sent a crew of [[Maximal]]s out into the universe aboard the starship ''[[Axalon (BW)|Axalon]]'', ostensibly to recover the Enigma of Combination. {{storylink|Hasbro Heroes Sourcebook issue 1|Centurion profile}} During the [[Ice Age]], ten thousand years ago, the ship visited Earth to refuel and was shot down by the younger Shockwave, who had returned to Earth to check on the progress of his Regenesis worlds. The [[Talisman (G1)|Talisman]] they had carried aboard their ship had wiped their memories; the younger Shockwave reprogrammed them, convincing them that they were key players in the Great War, and turned them against one another in a series of wargames. {{storylink|Strange Visitors}} Shockwave, however, had been tailed by the [[Dinobot (G1)|Dynobot tactical unit]], and both they and Shockwave were left buried in a volcanic eruption. {{storylink|Spotlight: Shockwave}} The lost Maximals retreated underground and entered hibernation. {{storylink|Strange Visitors}}

[[File:SinsoftheWreckers3 Ultra Energon.jpg|thumb|right|250px]]

Some time later, "Onyx" would again send an agent to Earth; this time, it would be the [[Titan Master]] [[Sovereign]], who disguised himself as a [[human]]. Evidence suggests that Sovereign arrived on Earth approximately six thousand years ago, {{storylink|Onyx Interface Part Two: Vs.}} in his modern-day guise as [[G.B. Blackrock|Garrison Blackrock]], he claimed that ancient humans had discovered the Enigma, and its energies had "combined" their thoughts and ideas, leading to the foundation of human civilization in [[Mesopotamia]], with [[Gilgamesh]] founding the city of [[Uruk]] to protect the artifact. {{storylink|Onyx Interface Part Three: ONoffON|ONoffON}}

At some point, the neutral scientist [[Tarantulas (BW)#2005 IDW continuity|Mesothulas]] visited Earth, and refined samples of Shockwave's ore into an artificial superfuel he dubbed "[[obtenteum]]." {{storylink|Sins of the Wreckers issue 3|Sins of the Wreckers #3}}

[[File:StrangeVisitors-HOSflashback.jpg|thumb|left|250px]]

In the late 1800s, construction of the Transcontinental Railroad inadvertently disturbed several of the hibernating Maximals; still believing themselves to be the Autobots and Decepticons, they lapsed into their old tactical simulations and the "Autobots" triumphed over the "Decepticons." {{storylink|Strange Visitors}} {{storylink|Hearts of Steel}} In the year 1888, they defeated the Elder God and its servants when the ancient being threatened Earth, {{storylink|Strange Visitors}} {{storylink|Infestation 2: The Transformers issue 2|Infestation 2 #2}} and remained active up until the outbreak of [[World War I]], when a combination of dwindling fuel levels and Shockwave's conditioning wearing off caused most of them to die. {{storylink|Strange Visitors}}

Other alien arrivals over the years would include the [[Dire Wraith]]s, shapeshifting aliens who sought to infiltrate human society and destroy it from within, {{storylink|Earthfall: Part Three}} and the [[Prysmosian]] wizard [[Merklynn]], who came to Earth searching for sufficient [[magic]]al power to restore his [[Prysmos|ruined homeworld]], disguised as the human "[[Garrison Kreiger]]." {{storylink|Schismatic}} By [[1945]], at the height of [[World War II]], "Krieger" came into contact with [[Centurion (IDW)|Centurion]], the last surviving Maximal, and the two formed an unlikely alliance to secure the Talisman that Centurion's ship had brought to Earth. {{storylink|Strange Visitors}}

[[Soundwave (G1)/2005 IDW continuity|Soundwave]], [[Laserbeak (G1)|Laserbeak]], and [[Ravage (G1)/2005 IDW continuity|Ravage]] arrived on Earth while spying on [[Bludgeon (G1)|Bludgeon]] and his team. {{storylink|Spotlight: Soundwave}} After briefly investigating the [[Tomb of Amtoltec]] in Egypt—the place where, by sheer coincidence, Krieger had recently unearthed the Talisman—{{storylink|The Secret of the Mummy's Tomb}} conflict between the two Decepticon groups triggered the eruption of [[Mount St. Helens]] in [[1984]]. In [[1985]], the underfunded government organisation [[Skywatch]] dug up the bodies of several of the deactivated Cybertronians, and used this find to secure more funding while also reprogramming them as mindless agents. {{storylink|Spotlight: Soundwave}} This, in turn, would lead to the development of [[Project Hot House|Project: Hot House]], which saw the involvement of both Krieger and Centurion. {{storylink|When Eagles Scream}}

Another unauthorised landing, this time by the rogue [[Scorponok (G1)|Scorponok]], occurred at an unknown point in time; he made contact with a number of amoral private corporations, leading to the formation of the [[Machination]]. {{storylink|Infiltration issue 4|Infiltration #4}}

[[File:AHM3-AirForceOne.jpg|thumb|right|200px]]

The planet was officially infiltrated by the Decepticons sometime during [[2002]] using standardized Deceptiocn [[infiltration protocol]], aiming to secretly undermine Earth's civilization; a detachment of Autobots, led by [[Prowl (G1)/2005 IDW continuity|Prowl]], followed them in an attempt to thwart their aims. Decepticon agents were placed in multiple areas, such as the [[Alexander Holt|United States government]] and the separatists of [[Brasnya]]. However, the recent discovery of [[Ore-13]] by [[Starscream (G1)/2005 IDW continuity|Starscream]]'s team prompted the treacherous lieutenant to break protocol in an effort to rebel against [[Megatron (G1)/2005 IDW continuity|Megatron]]. Autobot agent [[Ratchet (G1)/2005 IDW continuity|Ratchet]] also broke protocol by initiating direct contact with three humans, who proved invaluable in gaining intelligence on Starscream's operations. {{storylink|The Transformers: Infiltration|Infiltration}}

The discovery of Ore-13 threatened to make Earth the new front line in the war between the Autobots and Decepticons. Megatron carried on the standard strategem of igniting conflict between humans to weaken their kind for conquest, but Autobot interference made him escalate things drastically. The Transformers became known to humanity, with the Machination attempting to exploit this. {{storylink|The Transformers: Escalation|Escalation}} {{storylink|The Transformers: Devastation|Devastation}}

About a year on from this, [[The Transformers: All Hail Megatron|''everyone suddenly forgot'' they knew about the Transformers]], while a disgruntled [[Sunstreaker (G1)/2005 IDW continuity|Sunstreaker]] made a deal that saw the Decepticons gain an undefended Earth. A destructive war occurred between Decepticon and human, with [[New York City]] seized as a base and several other parts of the planet suffering devastating attacks. Eventually, Optimus Prime showed up in [[Omega Supreme (G1)|Omega Supreme]] and put a stop to that. {{storylink|The Transformers: All Hail Megatron|All Hail Megatron}}

[[File:ForAllMankind-rebuilding.jpg|thumb|left|250px]]

Their leader grievously wounded and their forces in tatters, the Decepticons retreated for the time being. With Autobot infrastructure across the galaxy in ruins, Earth became a hot spot of Transformer activity as Autobot refugees travelled to the planet in the hopes of seeking shelter. Most Autobots and Decepticons, however, were stranded on the world for some time, left to the mercies of an increasingly aggressive [[Skywatch]]. Several Decepticons forged alliances of convenience with Earth nations, while the Autobots were eventually able to form a joint team with Skywatch. {{storylink|The Transformers (IDW)|The Transformers}}

Most Cybertronians retreated back to Cybertron for the "Chaos War" that ultimately ended with Cybertron's revival and all Autobots on Earth being recalled to their homeworld, {{storylink|Transformers: The Death of Optimus Prime|The Death of Optimus Prime}} taking care to destroy any trace of Cybertronian technology they might have left behind. {{storylink|Secret Raiders: A Revolution Prelude|Secret Raiders}} While the Autobots were away, [[Skywatch]] was dissolved and reformed into the [[Earth Defense Command]]. {{storylink|New Cybertron Part 2: A Lonely Pillar on the Plain|A Lonely Pillar on the Plain}}

[[File:NewWorldsOrder-CouncilOfWorlds.jpg|thumb|right|250px]]

After the "[[Dark Cybertron (IDW)|Dark Cybertron]]" event, Galvatron took command of the Decepticons and came ''this'' close to conquering Earth ''twice'' in the span of a few days, Optimus Prime saw fit to annex Earth into the Cybertronian [[Council of Worlds]]. {{storylink|Conquerors Part 4: Perihelion|Perihelion}} While a controversial decision, it was overshadowed by the threat of [[Baron Karza]] nearly destroying Earth via the various Ore-13 deposits. After that threat had passed, Optimus invited all of Earth's protectors to work together in defence of the planet. {{storylink|Revolution}}

A few months later, a wandering tribe of [[Junkion (species)|Junkion]]s arrived on Earth, hoping to use the Ore-13 to repair their destroyed homeworld. {{storylink|New Cybertron Part 2: A Lonely Pillar on the Plain|A Lonely Pillar on the Plain}} Though their plan fell through, they took up residence on Earth, building a city for themselves that they dubbed "[[Little Cybertron]]." {{storylink|New Cybertron End: Feel Safe Without Regrets}}

Soon after, Earth elected [[Marissa Faireborn]] to be its first interstellar ambassador. {{storylink|Origin Myths}} In a twisted attempt to protect Earth however, [[Joe Colton]]'s [[Iron Ring]] attacked the ceremony with the intent to bring about the extinction of the Cybertronian race. Though his scheme was stopped, it had unwittingly awakened [[Unicron/Generation 1|Unicron]]. {{storylink|First Strike}}

[[File:Unicron6 Peace At Last.jpg|thumb|left|200px]]

When the Chaos Bringer began ripping Cybertron to pieces, the planet's population evacuated to Earth via the power of the [[Talisman (G1)|Talisman]], the device joining them in the teleport meaning Unicron followed the Transformers to the organic world. {{storylink|Road's End}} Once Unicron had been felled, the [[black hole]] that had once been at his core began orbiting the Earth. {{storylink|Ceremony}} Despite the existence of "New Cybertron", most Cybertronians evidently elected to stay on Earth, {{storylink|Post}} with [[Nautica (G1)|Nautica]] and [[Velocity (G1)|Velocity]] even moving there after the ''[[Lost Light]]'' had been decommissioned. {{storylink|How To Say Goodbye And Mean It: Part 2}}

Earth was one of many living planets spawned by [[Daiakuron]]; like all of Daiakuron's creations, the planet hid a robot form known as "[[Atlas (G1)|Atlas]]". {{storylink|The War Never Ends}} In prehistoric times, the Autobot vessel ''[[Ark (G1)|Ark]]'' crashed on a remote island somewhere in the North Sea. {{storylink|Stick To Your Guns}} Over the course of human civilization, various secret societies rose and fell, passing down the knowledge of a secret "Pit" that would awaken Atlas in times of great need. {{storylink|The War Never Ends}} 

A great body of evidence suggested that the histories of Earth and [[Cybertron (planet)|Cybertron]] were intertwined: the warped creation account given in the [[Cobranomicon]] claimed that [[Adam]] and [[Eve]] had encountered Cybertronians in the Garden of Eden, that the Biblical figure of {{w|Metatron}} was based on Megatron, and that the "serpent" within that garden had somehow impregnated Eve with the first member of the half-human race that would go on to serve the eldritch being known as [[Koh-Buru-Lah (creature)|Koh-Buru-Lah]]. Conversely, [[Galen]]'s existence implied that humans had somehow arose on, or migrated to, Cybertron during some prior era. {{storylink|Expelled from the Garden}} 

At some point during Earth's medieval age, Earth and Cybertron came into contact with one another, and the Viking warrior [[Thor FalkenHauser]] received a Cybertronian warhammer as a reward for his efforts during a war that involved the two planets. {{storylink|The War Never Ends}} Around this time, a group of [[Cobra]] druids took up residence in the North Sea and jealously guarded their "cave of the gods" from outsiders. {{storylink|Stick To Your Guns}}

By the 21st century, the latest in the line of secret societies was [[G.I. Joe (team)|G.I. Joe]], and the two worlds came back into conflict with one another when Megatron attacked the [[Solar System]] aboard Cybertron. {{storylink|I Saw Three Ships}} Under his control, Cybertron was made to collide with Earth, {{storylink|Pax Megatronus}} which was presumed destroyed by those on Cybertron when space dust and debris covered the metallic world. {{storylink|Earth: R.I.P.}} Fortunately, Earth was later revealed to have survived relatively unscathed, the collision having "only" blown a huge crater in the Atlantic Ocean. This crater turned into a new continent, while the debris knocked loose from the planet formed a second moon dubbed [[Luna Secundus]]. When [[Primus]] threatened the sun next, [[G.I. Joe (team)|G.I. Joe]] activated the "Atlas Protocol", transforming Earth into Atlas so that he could stop Primus.

In the aftermath of the conflict, Atlas returned to his hibernation, and some Autobots chose to stay on Earth to aid with reconstruction. Earth's new continent was populated by various displaced peoples and war refugees, including [[Scorponok (G1)|Scorponok]]'s dormant body, which in turn became a new home for [[Snake-Eyes]] and [[Scarlett]]. {{storylink|The War Never Ends}}

===''Beast Wars: Uprising''===
The passengers of the ''Ark'' awoke in 1984 and began conducting their battles across Earth. In these early days of their war, many conspiracy theories arose about the Transformers, some believing them to be [[Cobra]] weapons. {{storylink|Cultural Appropriation}}

Earth suffered greatly during the Great War between the Autobots and Decepticons; their destructive battles saw several cities and entire regions obliterated by orbital bombardments, human nuclear strikes, and collateral damage from robot wars.<ref>[http://www.allspark.com/forums/topic/133737-beast-wars-uprising-ama/?p=3362363 Post by Jim S on the Allspark Forums]</ref>

In the closing years of the 20th century, the Great War began to move off of Earth and returned to a cosmic scale. {{storylink|Micro-Aggressions}}

At some point during or after the 21st century, the [[Swarm (G2)|Swarm]] threatened to destroy the Earth. The planet was spared destruction through the efforts of [[Optimus Prime (G1)|Optimus Prime]] who sacrificed both his life and the [[Matrix of Leadership]] to purify the entity. The native population wasn't grateful in the slightest. {{storylink|Book of Logos}}

By the 24th century, a repaired Earth had become the capital of the utopian [[Human Confederacy]]. {{storylink|Micro-Aggressions}} Humans [[quantum lock]]ed Earth to prevent any future Cybertronian incursions. {{storylink|Intersectionality}} Returning to her dimension of origin from a [[Axiom Nexus|distant universe]], [[Blackarachnia (BW)|Blackarachnia]] attempted to reach Earth but was dragged off-course and crash-landed on the dystopian Cybertron of her birth. {{storylink|Broken Windshields}}

During his time in the [[Oracle (BM)|Oracle]], [[Overshoot]] experienced a vision of Earth and Cybertron orbiting the same star. The Oracle prophesied a time when Earth and Cybertron would stand together against a common threat, and, later, a time when the two diametrically opposed planets would merge into a single [[technorganic]] world. {{storylink|Cultural Appropriation}}

In the 25th century, schisms in human society caused the Confederacy to split into the [[Traditionalist]]s and the [[Celestial (faction)|Celestials]]. This factional divide eventually devolved into a state of civil war that marked a new Dark Age for the species, later recorded as the [[Fall of Man]], leaving the fate of Earth ultimately unknown. {{storylink|The Inexorable March}}

===''Star Trek vs. Transformers''===
[[File:STvsTF2-WWIII.jpg|thumb|left|300px]]
The Autobots and Decepticons crashed on Earth four million years ago, after the former group had destroyed an asteroid belt threatening Cybertron, before reawakening in [[1984]] and waging a secret war for the planet's energon supply. By the end of the 20th century, Earth experienced the [[Eugenics Wars]]; the subsequent outbreak of [[World War III]] at the beginning of the 21st century convinced the Autobots to flee the planet aboard [[Fortress Maximus (G1)|Fortress Maximus]], and the [[Decepticon]]s followed suit. Witnessing the brutality humanity was capable of inflicting upon itself left both factions with a particularly low opinion of the human race. {{storylink|Prime's Directive, Part Two}} 

Some two hundred years later, Earth had recovered from these conflicts, and had become a member of the interstellar [[Federation]] after the invention of warp travel. {{storylink|Prime's Directive, Part One}}

On stardate 5892.7, in the 23rd century, once [[Megatron (G1)|Megatron]] had been defeated, Captain [[James T. Kirk|Kirk]] invited [[Optimus Prime (G1)|Optimus Prime]] back to Earth, though Optimus turned down the offer, feeling that the destiny of his Autobots lay elsewhere. However, he swore to come to Earth's defence should the Federation require their aid in the future. {{storylink|Prime's Directive, Part Five}}

===''Transformers/Ghostbusters''===
[[File:GhostsOfCybertron1-Ectotron.jpg|thumb|right|250px]]

While still an underdeveloped world, Earth was discovered and mapped by Cybertronian astronomers. {{storylink|Ghosts of Cybertron Part 3}} Earth had been visited by the extradimensional deity known as [[Gozer]] in the past, and had been repelled by the efforts of the four-man band of paranormal investigators who called themselves the [[Ghostbusters]]. {{storylink|Ghosts of Cybertron Part 2}} {{storylink|Ghosts of Cybertron Part 4}} A thousand years after Gozer's destruction of Cybertron, the Autobot [[Ectotron]] was dispatched to Earth to investigate a mysterious signal, which turned out to belong to a [[ghost]]ly Starscream. {{storylink|Ghosts of Cybertron Part 1}}

After aiding the Ghostbusters in defeating [[Killerwatt|an electrical ghost]], Ectotron called Optimus Prime to Earth. {{storylink|Ghosts of Cybertron Part 3}} With the Autobot duo, the Ghostbusters confronted [[Kremzeek]] the Scavenger, who sought to absorbed the power of the [[AllSpark]], using the electrical ghost to dissipate him. This however, had the side-effect of releasing the ghosts of [[Decepticon High Command]], once trapped within the Scavenger's form. {{storylink|Ghosts of Cybertron Part 4}}

After the Decepticon ghosts, bar Starscream, were imprisoned, the Autobots left Earth. Though Optimus returned to the ''Ark'', Ectotron decided to travel the galaxy in search of any other Cybertronian ghosts, becoming the first interstellar Ghostbuster. {{storylink|Ghosts of Cybertron Part 5}}

===''Transformers vs. The Terminator''===
Millions of years prior to the human era, the ''Ark'' crashed on Earth, knocking the Autobots and Decepticons aboard in stasis. In the year 1984, the ship rebooted and reactivated Skywarp who proceeded to revive the rest of the Decepticons. After the Decepticons had executed the slumbering Autobots, they proceeded to conquer Earth, wiping out humanity. The organization that had formed to fight the Decepticons, [[Skywatch]], left behind the artificial intelligence that called itself [[Skynet]] to fight in their stead but it found itself outmatched and feigned surrender to the Decepticons to survive. {{storylink|Enemy of My Enemy Part Two}} In secret, Skynet began constructing a [[time displacement device]] to retroactively win the war. Though Skynet managed to send a single [[T-800]] back to 1984 with instructions to destroy the Cybertronians before they emerged and ensure the AI's creation, the Decepticons executed it shortly after the temporal displacement in [[2029]]. {{storylink|Enemy of My Enemy Part One}}

In the new timeline, the intervention of the T-800 caused the Autobots to survive, Optimus Prime proposing an alliance between the unit and the Autobots to protect Earth. The Decepticons had scouted the nearby areas before launching an attack on a [[Cyberdyne Systems]] facility. {{storylink|Enemy of My Enemy Part Two}} Further intervention of the T-800 brought the Great War to an end but not before the unit had destroyed the ''Ark''. Unable to return home, the eight Cybertronians remaining on Earth declared a truce until they could leave the planet. {{storylink|Enemy of My Enemy Part Four}}

===''Transformers/Back to the Future''===
Four million years prior to 1984, the ''Ark'' crash-landed on Earth, the impact knocking the Autobots and Decepticons into stasis lock. When the passengers rebooted, they resumed their war. {{storylink|Transformers/Back to the Future issue 2|Transformers/Back to the Future #2}} A year later, Rumble and Frenzy had been sent to scout [[Hill Valley]] for any potential advantages, discovering [[Doc Brown]]'s [[DeLorean time machine]]. When they attempted to claim it, Bumblebee confronted them, killing Ravage {{storylink|Transformers/Back to the Future issue 1|Transformers/Back to the Future #1}} while Rumble stowed away on the DeLorean, jumping forwards to 2015 with Brown. The two discovered a technologically advanced Earth but also that the Decepticons had been brought to the point of defeat.

Stealing the DeLorean, Rumble travelled back in time to reactivate only the Decepticons. In this new timeline, the Decepticons quickly conquered Earth, turning the planet into a production facility for [[energon cube]]s. By 2015, the Decepticons were the masters of Earth, the Autobots reduced to a small resistance. Unable to ignore his conscious any longer, number-cruncher [[Gigawatt]] scanned the DeLorean with the intent of undoing his master's reign only for Megatron to shoot him in the [[flux capacitor]]. After defecting to the Autobots, they sought out Brown to have him repair the capacitor. {{storylink|Transformers/Back to the Future issue 2|Transformers/Back to the Future #2}}

After the Autobots had found Brown and he'd repaired the flux capacitor, Gigawatt and [[Marty McFly]] time travelled to 1984 and awoke the Autobots ahead of schedule, allowing them to ambush Rumble. While Marty took the DeLorean back to Brown in 2015, the Autobots took the slow path to the future, keeping a silent vigil on Earth with [[Biff Tannen]] as a local guide. {{storylink|Transformers/Back to the Future issue 4|Transformers/Back to the Future #4}}

Sixty years before the present day, a crew of Autobots was dispatched to the planet to find and reactivate this [[Titan (group)|Titan]]; {{storylink|Koji Gets His Wish}} reduced to their [[protoform]] state, however, the stasis-locked crew were unable to prevent their ship from crash-landing somewhere in the United States. {{storylink|The Decepticons}} 

At some point afterwards, Earth would be visited by a group of Autobots, led by [[Optimus Prime (RID)|Optimus Prime]], followed by Megatron's own [[Predacon (BW)|Predacon]]s.

Fleeing the depredations of [[Megatron (Armada)|Megatron]]'s [[Decepticon]]s, the [[Mini-Con]] starship ''[[Exodus (Armada)|Exodus]]'' broke apart as it entered the Solar System a million years ago; half of the ship crashed on prehistoric Earth, while the other half crash-landed on the [[Moon (moon)|Moon]]. 

In the present day, the ship would be found by a the humans [[Rad White|Rad]], [[Alexis Thi Dang|Alexis]], and [[Carlos Lopez|Carlos]] on the outskirts of [[Science City]]. While investigating the ship, the three children triggered a homing beacon that alerted both Autobots and Decepticons to the presence of the power-enhancing Mini-Cons, with the Decepticons utilizing a [[space bridge]] to reach the planet. {{storylink|Dreamwave Armada issue 3|Armada #3}} The surge caused several other groups of Mini-Cons scattered across the planet to reawaken; {{storylink|Dreamwave Armada issue 5|Armada #5}} wanting no part in the war, and unwilling to be used as weapons by either side, these scattered cells of Mini-Cons began making preparations to leave the planet as soon as possible. As the war spilled over onto Earth, [[Optimus Prime (Armada)|Optimus Prime]]'s Autobots set up [[Autobase|their base of operations]] in [[Lincoln, South Dakota]], while Megatron's Decepticons similarly set up a command post in the abandoned town of [[Silver Ridge]]. {{storylink|Dreamwave Armada issue 6|Armada #6}} 

[[File:Armada13-SolarScalpel.jpg|thumb|right|250px]]

Unbeknownst to these Mini-Cons, their Moon-based compatriots, led by [[Dualor (Armada)|Dualor]], had commissioned the construction of a [[Mini-Con Ark]] that would retrieve their Earthbound compatriots... whether they wanted to leave, or not. {{storylink|Dreamwave Armada issue 8|Armada #8}} Conflict broke out between [[Sparkplug (Armada)|Sparkplug]]'s team of Autobot loyalists, their human commpatriots, and Dualor's independent faction, {{storylink|Dreamwave Armada issue 10|Armada #10}} though the debate was rendered moot when Megatron attacked their lunar fortress and captured several of the independent Mini-Cons, {{storylink|Dreamwave Armada issue 11|Armada #11}} with the rest boarding escape pods that fired them back to Earth. {{storylink|Fire & Ice}}

Subsequently, Earth was visited by [[Over-Run (Armada)|Over-Run]], a traveller from an alternate dimension, who desperately tried to warn this reality's iteration of Optimus that [[Unicron]] would soon arrive. {{storylink|Dreamwave Armada issue 13|Armada #13}} Indeed, Earth was soon attacked by a reality-hopping [[Galvatron (G1)|Galvatron]] and his forces, heralds of Unicron from a distant reality, and whose arrival caused dimensional ructions across both Earth and Cybertron. {{storylink|Worlds Collide, Part 1 of 4}} Earth briefly became the rallying point for all of the Mini-Cons as they assembled to forestall Unicron as the planet-eater attacked Cybertron. {{storylink|The End (Armada)|The End}}

Ten years later, a wounded but still-living Unicron sent his new Decepticon servants to attack Earth in the hopes of stealing its supplies of [[energon]]. {{storylink|This Evil Reborn}} Numerous [[Terrorcon (Energon)|Terrorcon]]s attacked [[Australia]], {{storylink|What Lies Beneath}} and briefly established an energon collection rig {{storylink|What Lies Beneath, Part Two}} before [[Kicker Jones|Kicker]] destroyed it. {{storylink|What Lies Beneath, Part Three}} 

On 2015, shortly after the beginning of the Terrorcon conflict, the [[United Nations]] ratified the [[Cybercord Treaty]] after the Autobots made themselves known on Earth; some humans viewed this with mistrust, believing that the Autobots were plotting invasion. {{storylink|Multiplicity}} More Terrorcons attacked several human cities, forcing Optimus into releasing Megatron from Unicron to defend the planet, {{storylink|Multiplicity, Pt. 4}} his presence singlehandedly turning the tide of the fight. {{storylink|No Exit}}

After the first defeat of [[Unicron]], Earth was chosen as one of the planets to receive a [[Cyber Planet Key]], which would have reformatted the planet into a Transformer colony. However, the colony ship ''[[Atlantis]]'', also carrying the [[Omega Lock]], crashed onto the planet before it could properly begin its mission. {{storylink|Deep}} The colonists survived the crash however becoming urban legends and myths in human society from thereon. {{storylink|Trap}}

As Cybertron fell to the Great War, the [[Mini-Con]] sub-species fled the planet aboard the ''[[Exodus (Armada)|Exodus]]''. Before they could enter [[unspace|transwarp]] however, the Decepticon fleet struck damaging the escape ship's engines. Once the ship jumped, it emerged above Earth's moon, the crash splitting it in two and scattering most of the [[Mini-Con storage panel]]s across Earth. {{storylink|First Encounter}}

The panels containing the [[Air Defense Mini-Con Team (Armada)|Air Defense Mini-Con Team]] were found by a group of humans, who used the Mini-Cons' power to construct a thriving civilization, only for their power to push their enemies to attack them and destroy their advanced utopia. {{storylink|Ruin}}

In 2010, the Mini-Cons on Earth were reactivated which brought [[Optimus Prime (Armada)/Cartoon continuity|Optimus Prime]] and [[Megatron (Armada)/Cartoon continuity|Megatron]]'s squadrons to the planet to try and claim the living weapons. {{storylink|First Encounter}} Earth itself would nearly be destroyed by the [[Hydra Cannon]] only being saved by Optimus Prime's sacrifice. {{storylink|Crisis (Armada)|Crisis}}

When the Autobot/Decepticon war moved back onto Cybertron, it was revealed Earth's involvement in the Mini-Con battles was a form of predestination. Thanks to some timey-wimey circumstances that no one bothered to explain, [[Rad White]] was sent back to the moment of the Mini-Cons' birth where he imbued them with sentience and told High Wire to come to Earth where they would meet. {{storylink|Drift (episode)|Drift}}

[[File:E4 Terrorcon Attack.jpg|thumb|left|250px]]

Once Unicron had been (largely) destroyed, the Transformers announced their existence to Earth, the humans forming the [[Earth Federation]] and working alongside the mechanical aliens as partners in their galaxy wide hunt for [[energon]]. By 2020, this alliance had colonies across the solar system and beyond. {{storylink|Cybertron City (episode)|Cybertron City}}

When Unicron had been destroyed (for realisies this time), his death caused the formation of a [[Unicron Singularity|black hole]] so powerful, its gravity field warped space/time erasing Earth's knowledge of the Transformers and reverting the planet to a pre-space age state. {{storylink|Revelations Part 2}} When the black hole threatened to consume Cybertron, Optimus Prime evacuated the civilians to Earth where he and his troops set up their base while they hunted for the Cyber Planet Keys. {{storylink|Fallen (episode)|Fallen}}

Once it became clear that Earth was home to a Cyber Key, [[Starscream (Armada)/Cartoon continuity|Starscream]] dropped all subtlety and openly invaded the planet in his search for it. {{storylink|Invasion (episode)|Invasion}} After the third key was found, the Autobots returned to Cybertron to try and close the black hole. {{storylink|Cybertron (episode)|Cybertron}}

{{note|The six movies are the primary component of the live-action movie continuity family. Their events should be taken as canon for all other pieces of fiction listed below, unless otherwise specified.}}

====''Bumblebee'' film====
As the Decepticons overran Cybertron, Optimus Prime dispatched [[Bumblebee (Movie)|B-127]] to Earth, hoping to use the planet as a fallback point for the Autobots as they fled the planet. When the scout landed on Earth, sometime in the year [[1987]], he was attacked by [[Blitzwing (BB)|Blitzwing]], his injuries resulting in amnesia. When [[Shatter]] and [[Dropkick (Movie)|Dropkick]] captured and interrogated B-127, they learned of Prime's plans for Earth, and attmepted to summon the [[Decepticon fleet]] to bait a trap for their foes. B-127, or Bumblebee as he now called himself, managed to stop the transmission from being sent, with help from [[Charlie Watson]] and [[Jack Burns]], before going off to meet with the Autobots as they arrived on Earth. {{storylink|Bumblebee (film)|Bumblebee}}

====''Transformers'' film====
[[File:Earth Transformers landing.jpg|thumb|left|300px|Where pleasure follows pain, and people go insane. Fly around in planes and pray that it won't rain.]]

The AllSpark itself crashed onto Earth approximately 10,000 B.C.E., followed a few thousand years later by the Transformer [[Megatron (Movie)|Megatron]] who would become buried at the Arctic Circle. The inadvertent discovery of the latter by Captain [[Archibald Witwicky]] would, eventually, lead to the formation (at [[Sector Seven#Notes|...some point]]) of the [[Sector Seven]] organisation, a United States secret service meant to handle "non-biological entities". [[Hoover Dam]] would be built as a secret holding base for Sector Seven, near to populous [[Mission City]].

By covertly reverse-engineering this advanced Cybertronian technology, human technological development rapidly increased, and by the modern day most electronic technology owed something to Megatron. The United States had thus become so powerful the [[United States military]] possessed [[SOCCENT Forward Operations Base|bases]] in foreign countries such as [[Qatar]] and [[NASA]] had [[Beagle 2 Rover#Notes|total supremacy]] over space-related matters. Sector Seven had its own paramilitary wing and [[Section N44E|prisons]], all while being so secret the [[John Keller|Secretary of Defence]] was unaware of its existence.

The Autobot [[Bumblebee (Movie)|Bumblebee]] was sent to Earth to find the AllSpark, and in the summer of 2007 the Decepticons arrived on Earth in search of both the AllSpark and their leader, learning of [[Archibald Witwicky's glasses]], upon which the physical location of the AllSpark was imprinted. [[Optimus Prime (Movie)|Optimus Prime]] and the Autobots arrived on Earth to secure the AllSpark. Open warfare would result, ending in a final battle with both the military and the Autobots fighting against the Decepticons at Mission City. Sector Seven were decimated and the AllSpark cube destroyed, but the Decepticons were defeated and Megatron killed thanks in part to [[Sam Witwicky|two]] [[Mikaela Banes|youths]]. Sector Seven was tasked with cleanup, making a brief, if shaky, alliance with the Autobots to escort the remains of the Decepticons for dumping in the [[Laurentian Abyss]], before the organization was shut down for its inept management of the crisis. {{Storylink|Transformers (film)|Transformers}}

====''Revenge of the Fallen'' film====
[[File:ROTF great battle.jpg|thumb|right|300px|And this is... erm... well, I can't tell. But it's exciting, honest!]]

In 17,000 B.C.E., the [[Dynasty of Primes]] came to Earth with their warriors and workers to build a [[Star Harvester]], a machine that drained the power of the sun in order to recharage the AllSpark. Just as they finished the Harvester, the Primes discovered the primitive humans. Most of the Primes upheld their rule of sparing life, but one Prime, forever known as [[The Fallen]], despised the humans as insects and sought to seize the AllSpark's power for himself. A great battle took place, but in the end, the Dynasty of Primes stole the [[Matrix of Leadership]], the key to activating the harvester, and hid it in a [[Tomb of the Primes|tomb]] made of their bodies. The harvester was abandoned on Earth, in the country that would be called [[Egypt]]. The native humans built a [[Great Pyramid of Giza|pyramid]] over the device. 

Over the years, Decepticons who called themselves [[Seeker (ROTF)|the Seekers]] travelled to Earth in the hopes of finding the Matrix of Leadership. Symbols and pictures of them ended up on ancient human relics; in time, however, the majority ran low on energon and went dormant, entering a protective [[stasis lock]].

[[File:Rotf t2 egyptpyramids.jpg|thumb|left|250px|Pyramids hide the Harvester inside.]]

By [[2009]], [[Barack Obama]] was the President of the United States, with [[Theodore Galloway]] as National Security Advisor and General [[Morshower]] as Chairman of the Joint Chiefs of Staff; [[China]] was on such good terms with America that it allowed an American dominated international military coalition to operate in [[Shanghai|its cities]], and Egypt and [[Jordan]] had established a border with each other. Sector Seven had been replaced by [[NEST]], a joint human-Autobot taskforce that hunted down rogue Decepticons across the globe. 

That same year, Megatron was revived, and was tasked by his master The Fallen with retrieving Sam Witwicky and killing Optimus Prime. Failing in the former but succeeding in the latter, Megatron decided to escalate the war with the Autobots by making overt attacks, with strikes on Earth cities and the destruction of a major [[pyramid]] before the Autobot/NEST team won when Sam Witwicky used the Matrix to revive Optimus Prime, who in turn defeated Megatron and killed The Fallen. {{storylink|Transformers: Revenge of the Fallen (film)|Revenge of the Fallen}}

====''Dark of the Moon'' film====
[[File:DarkoftheMoon-Chicago.jpg|thumb|right|250px]]
In [[1961]], the ''Ark'' crashed on Earth's moon, sparking the space race. By 1972, Soundwave and Laserbeak had landed on Earth and coerced humans into helping them end the space race to protect the ''Ark'' from discovery. Sector Seven was involved in the American effort to explore the ''Ark''.

A few years after the death of the Fallen, the Autobots and Decepticons were public knowledge and [[energon detector]]s were set up in all of Earth's major cities to detect Decepticon forces. By this point, the war seemed to be in a peaceful lull as there hadn't been a major Decepticon engagement in a while and the Autobots were helping to deal with humans who were threats to world security, sometimes of their own initiative and against the American government's wishes. After a trip to Chernobyl uncovered an engine part from the ''Ark'', Optimus Prime and Ratchet traveled to the moon and recovered five [[pillar]]s and [[Sentinel Prime (ROTF)|Sentinel Prime]], who was brought back to life with the Matrix of Leadership. 

This played right into the Decepticons plans as they needed Sentinel to use the space bridge to bring an army to Earth and to bring Cybertron as well, so the Decepticons could conquer Earth and use its resources and human population to rebuild [[Cybertron (planet)|Cybertron]]. Most of the Decepticon army invaded [[Chicago]], killing countless humans while a few Decepticons spread around the planet to release the space bridge. In Chicago, a massive battle occurred in which a combined force of Autobots and humans assaulted the Decepticon-held city. In the end, Chicago was liberated and the Decepticon army was destroyed along with the space bridge, Sentinel and Cybertron, forcing the Autobots to accept Earth as their new home. {{storylink|Transformers: Dark of the Moon (film)|Dark of the Moon}}

====''Age of Extinction'' film====
[[File:ExtinctionOfTheDinosaurus.jpg|thumb|left|250px]]

65 million years ago, a mysterious race known only as the [[Creator]]s came to Earth, cyberforming swathes of the planet with their specially-engineered [[Seed]]s that transmuted everything it touched into elemental metal. The native dinosaurs were caught in the blast radius, resulting in their mass extinction which humans would initially believe to have been the work of an asteroid impact. For unknown reasons—presumably they only wanted to mine the [[Living metal|transformium]] that their Seeds had created—the Creators then left Earth, allowing its organic life to take over once again. 

In the modern day, following the battle of Chicago, NEST was succeeded by [[Cemetery Wind]], an extragovernmental authority that used its power to indiscriminately hunt down Autobots and Decepticons alike with the help of the unaligned Cybertronian [[Lockdown (ROTF)|Lockdown]]. Though Earth was briefly threatened by the detonation of another Seed, Optimus Prime was able to take it off-planet before it could explode, saving the planet. {{storylink|Transformers: Age of Extinction (film)|Age of Extinction}}

====''The Last Knight'' film====
[[File:TLKEnding.jpg|thumb|right|250px]]
Billions of years ago, the Earth formed around the inert body of Unicron, the Chaos Bringer. In time, continental drift would break up his physical form; primitive peoples would build [[Stonehenge]] over the point where Unicron's horns had once aligned.

Various Transformers had visited Earth over the years; these included both Bumblebee and [[Hot Rod (DOTM)|Hot Rod]], who joined the Allies during [[World War II]].

When [[Quintessa (TLK)|Quintessa]] discovered Earth's true origins, she saw a chance to revive Cybertron by draining Unicron's lifeforce, which had a side effect of destroying Earth. When she moved Cybertron into Earth's orbit to commence the ritual that would revive her homeworld, Unicron's horns sprouted from the Earth in response to Primus' proximity. While the Autobots managed to halt the ritual, Cybertron was left parked above the Earth and Unicron's horns remained jutting out of the planet's crust. {{storylink|Transformers: The Last Knight (film)|The Last Knight}}

Circa 17,000 BC, The Fallen brought his Decepticons to Earth to begin the creation of a star harvester, deliberately baiting his brothers into a trap. {{storylink|Tales of the Fallen issue 3|Tales of the Fallen #3}} Seven thousand years later, the AllSpark would crash on Earth, cosmically drawn to the energy emitted by the star harvester left behind by The Fallen. 

Acting on orders from the Fallen and his ally of convenience [[Sentinel Prime (ROTF)|Sentinel Prime]]—the latter seeking to strip Earth of its resources in order to rebuild his homeworld—Megatron would puruse the AllSpark to Earth, but crash-landed in the Arctic, frozen solid. {{storylink|Defiance issue 4|Defiance #4}} {{storylink|Movie Prequel issue 2|Movie Prequel #2}} One of the Fallen's Seekers, the repentant warrior [[Jetfire (Movie)|Jetfire]], would go on to inadvertently cause the [[Spain|Spanish]]-American War after the founders of Sector Seven inadvertently triggered an energy pulse while investigating Megatron's systems. {{storylink|Original}}

===Sector Seven ARG===
[[File:Lunchables brigade.jpg|thumb|right|250px|What the hip kids will wear in the far future of 2007.]]

On [[August 15]], [[1977]], the "Big Ear" radio telescope detected a Cybertronian radio signal emanating from the Sagittarius constellation. Five years later, Cybertronian sightings on Earth prompted a response in the form of "[[Hungry Dragon|Operation Hungry Dragon]]:" a Sector Seven-backed campaign that, in association with [[TakaraTomy|Takara]], produced an assortment of toys and fiction themed around the N.B.E.s, supposedly as part of a video game. This allowed Sector Seven to dismiss any claims relating to the Transformers or their world as fictional characters.

A second surge of Transformer activity in the years [[2003]] to [[2006]] led to the creation of "[[Hungry Dragon|Hungry Dragon 2]]," this time based around a live-action film. Bumblebee landed on Earth in April 2007. Desperate to warn the planet of an impending Decepticon invasion, and unable to convince Sector Seven to cooperate, Optimus instead transmitted vital information to the Earth-based radical cell known as the [[Lunchables Brigade]]. 

On [[June 9]], 2007, a third faction of Cybertronians, the mysterious "[[Mountain Dew Robot]]s," attempted to infiltrate Hoover Dam, possibly as part of their nefarious plot to conquer the Earth and found the dystopian "[[Dew City]]." Finally, on [[July 4]]th, a massive spate of Transformer activity was covered up, blaming the battle on malfunctioning robot prototypes. {{storylink|Sector Seven (game)}}

In a further [[Tyran 208.28 Gamma|divergent timeline]], the Decepticons succeeded at Mission City and conquered the United States. While [[NATO]] regrouped to try and oppose them, its forces proved no match for Decepticon retaliation. The crisis caused [[Russia]] to join up with NATO, and resulted in extensive damage to [[France|Paris]], including the loss of the French centre of government. {{storylink|Transformers Comic issue 10|Twilight's Last Gleaming, Part: 2}}

Via a processing station at [[Savannah]], [[Georgia]], Megatron used the AllSpark to begin transforming Earth into a new Cybertron. The Autobots eventually killed him and destroyed the AllSpark, {{storylink|Transformers Comic issue 13|Twilight's Last Gleaming, Part: 5}} but the fundamental damage was already done: [[Earth's core]] was infected, causing the planet to be torn apart by continuing techno-organic activity. {{storylink|Transformers Comic issue 17|Return to Cybertron: Part 1}} ''Un''natural disasters spread across the Earth, along with areas spewing out raw [[energon]] and a strange illness affecting scores of people. This would eventually be stopped with [[Nucleon (substance)|Nucleon]]. {{storylink|Transformers Comic issue 20|Return to Cybertron: Part 4}}

On top of this, attempts to rebuild the liberated United States were constantly thwarted by a Decepticon terror campaign; both Autobot and NATO forces (the American military having been decimated) operated on US soil, attempting to defend it. The Decepticons eventually re-conquered 600+ miles of US territory centred on Savannah, claiming it as an autonomous [[Decepticon Heartland]]. {{storylink|Transformers Comic issue 20|Return to Cybertron, Part: 4}} To make matters worse, the Decepticons had mental control over hundreds of human officials, including [[Theodore Allen|the US President]], and used them to force America to seek a diplomatic deal and thus leave itself easier to conquer. While the Autobots eventually defeated the Decepticons, the mind-controlled slaves and [[drone]] soldiers were littered across the country. {{storylink|Transformers Comic issue 25|Revolution Part Three}}

===Bumblebee's Mission Log===
The rogue Decepticon general [[Mainframe (Movie)|Mainframe]] reached Earth before the Autobots and established an army and base at the Arctic.

===Ask Vector Prime===
In [[Tyran 609.23-PX Kappa|a divergent parallel reality]], Megatron killed The Fallen during the battle in Egypt, and the united Decepticon advance pushed NEST and the Autobots back. Manipulated by Soundwave, Optimus found and reactivated the ''Ark'', only to learn that Sentinel Prime was an ally of Megatron's, and used space bridge technology to pull Cybertron into Earth orbit. Humanity was enslaved and made to strip-mine their world so as to repair Cybertron, with the [[Cemetery Wind]] taskforce commissioned to hunt down rogue Autobots. 

When Lockdown arrived, however, Sentinel and Megatron refused to turn over Optimus to the [[Creator]]s, despite the bounty hunter offering them a Seed. Eventually, Optimus was able to return Sentinel to the side of good, and the two Primes were able to double-cross Lockdown and destroy him. Though a long war ensued against the Decepticons, Earth was eventually freed from the Decepticons, and Cybertron restored with the stolen Seed. {{storylink|Ask Vector Prime#Facebook|Ask Vector Prime, 2015/07/22}}

The planet Earth lay just beyond the [[Quintesson Pan Galactic Co-Prosperity Sphere]]. {{storylink|Transformers Animated: The AllSpark Almanac II|The AllSpark Almanac II}} On [[July 15]]th, some time in the late 21st century, [[Megatron (Animated)|Megatron]] and the [[Autobot]] ship ''[[Omega Supreme (Animated)|Orion]]'' crash-landed in [[Michigan]]. {{storylink|Transformers Animated: The AllSpark Almanac|The Allspark Almanac}} {{storylink|Transform and Roll Out}}

Momentous events happened throughout the 21st and 22nd centuries, before; these included the colonization of [[Mars (planet)|Mars]], the solving of world hunger through the [[Los Bogos Project]], the dissolution of the [[United Kingdom]], and a war against the evil [[Inhumanoid]]s. {{storylink|Transformers Animated: The AllSpark Almanac II|The AllSpark Almanac II}}

By the 22nd century, the global economy had been permanently changed by the development of advanced robotic technology. The centre of this development was [[Detroit]], where [[Isaac Sumdac (Animated)|Isaac Sumdac]] had set up the headquarters of his company, [[Sumdac Systems]]... though none were aware that this miraculous leap forward had come from the engineer's study of Megatron's deactivated head. {{storylink|Transform and Roll Out}}

Although these advanced technological developments also [[Professor Princess|also]] [[Nanosec|led]] [[Slo-Mo|to]] [[Colossus Rhodes|numerous]] [[Angry Archer|supervillains]] and [[Street Demon|other]] forms of advanced criminal activity, at least [[Wraith|one superhero]] has also arisen.{{storylink|Transformers Animated: The AllSpark Almanac II|The AllSpark Almanac II}}

After the Autobots had awoken, their super-heroics caught the attention of [[Starscream (Animated)|Starscream]] who came to Earth to claim the [[AllSpark]]. In his struggle with [[Optimus Prime (Animated)|Optimus Prime]], the two accidentally activated the AllSpark, {{storylink|Transform and Roll Out}} altering the rest of the Cybertronian race to Earth's location. {{storylink|Dispatches}}

The first Cybertronian to arrive was [[Lockdown (Animated)|Lockdown]], seeking to claim a Decepticon bounty on Optimus in retaliation for Megatron's presumed deactivation. {{storylink|The Thrill of the Hunt}} In the form of two of Megatron's lieutenants, [[Lugnut (Animated)|Lugnut]] and [[Blitzwing (G1)|Blitzwing]], the Decepticons eventually arrived on Earth. With the former guided by Megatron, the two Decepticons sought to claim [[Sari Sumdac (Animated)|Sari Sumdac]]'s [[AllSpark Key]] and use it to find the AllSpark. Though the Autobots were able to defeat the two Decepticons, they were conscious that more Decepticons would follow and sought to repair their ship so as to take the AllSpark away from the heavily populated Earth. {{storylink|Lost and Found (episode)|Lost and Found}}

When Megatron managed to reconstruct himself, {{storylink|Megatron Rising - Part 1}} the Autobots quickly tried to leave Earth only for their craft to be shot down before it could even leave Detroit airspace. {{storylink|Megatron Rising - Part 2}}

Not long afterwards, the Autobot [[Elite Guard]] touched down on Earth, intending to return the AllSpark to Cybertron only to learn that it had been dispersed in a battle with the Decepticons. While Optimus Prime's team managed to produce an AllSpark fragment as proof of the AllSpark's continued existence, {{storylink|The Elite Guard}} they were unable to offer proof of a continued Decepticon presence on Earth. As such, [[Ultra Magnus (Animated)|Ultra Magnus]], in the light of the recent [[Decepticon Uprisings]], decided that it was best to withdraw all Autobots from Earth before Starscream crashed in front of him. With that information, the Elite Guard took the Seeker back to Cybertron while letting Prime's team handle the reconstitution of the AllSpark and the Decepticons on Earth. {{storylink|Mission Accomplished}}

While in transit back to Cybertron, Starscream escaped Elite Guard custody and made his way back to Earth to reek terrible revenge on Megatron. Hearing of the escape, Megatron put out a bounty on the traitor which brought Lockdown back to Earth in an attempt to claim it. {{storylink|A Fistful of Energon}}

To keep an optic on Prime's crew, the Elite Guard sent [[Blurr (Animated)|Blurr]] to Earth. The intelligence agent discovered that Megatron sought to use a reverse-engineered space bridge to conquer a weakened Cybertron from within, meeting up with Prime's team to destroy the portal. {{storylink|A Bridge Too Close, Part I}} The situation was made worse by Starscream's clone army and the reactivation of Omega Supreme. When the space bridge began to overload, Megatron, Starscream - now reduced to just a head - and Omega Supreme were all warped off Earth, the latter's departure stranding the Autobots on the organic planet. {{storylink|A Bridge Too Close, Part II}}

Via the AllSpark fragment in Starscream's head, Megatron managed to assume control of Omega Supreme. With the giant having absorbed enough transwarp energy to jump across the galaxy on his own, Megatron returned to Earth and made an attempt to use the Sentinel to destroy his foes. When Starscream instead took control, Megatron convinced him to abandon Earth outright and make for Cybertron instead. Before the two left, the Autobots managed to lodge a [[plasma dynamic thruster]] in Omega's alternate mode, sending the Decepticons on a galactic tour. {{storylink|TransWarped}} Deprived of Omega, the Autobots instead turned their resources into building a space bridge to make their way off Earth. {{storylink|Three's a Crowd}}

When the escaped Autobot loon [[Wasp]] made his way to Earth, the Elite Guard followed where they learnt that Longarm Prime was really the Decepticon double agent [[Shockwave (Animated)|Shockwave]]. {{storylink|Where Is Thy Sting?}} The Guard remained on Earth for a while longer to round up Megatron's elite, [[Sentinel Prime (Animated)|Sentinel Prime]] making liberal use of Lockdown's talents to round them up, {{storylink|Five Servos of Doom}} before leaving Earth. {{storylink|Predacons Rising (Animated)|Predacons Rising}}

When Optimus received [[Broken Lance|a distress signal]] from Sentinel Prime, he transwarped to the ''Steelhaven'' to provide aid in combating the escaped Decepticon prisoners. With his aid, the Elite Guard managed to retake the ship but lost custody of Lugnut and Swindle. By way of thanks, the ''Steelhaven'' briefly returned to Earth to drop Optimus off. {{storylink|Decepticon Air}}

When [[Ratchet (Animated)|Ratchet]] used the completed Earth space bridge to lock onto Omega Supreme, he wound up warping himself and [[Carmine Fanzone|Captain Fanzone]] to Cybertron. After an adventure there, they returned to Earth, accompanied by Jazz. {{storylink|This Is Why I Hate Machines}}

When Megatron managed to clone Omega Supreme, he sent the [[Lugnut Supreme]]s against Earth as a field test. {{storylink|Endgame, Part I}} Rallying all their assets, the Autobots managed to defeat the clones before they said goodbye to Earth to triumphantly return to Cybertron with their Decepticon prisoners. {{storylink|Endgame, Part II}}

When humanity built the [[GoBots|Go-Bots]], the androids spread to every corner of Earth. {{storylink|Go-Bots issue 1|Go-Bots #1}} The Go-Bots were kept in check by their [[G-chip]]s and the [[Asimov Laws]], which prevented them from bringing harm to humans. The [[United States military]] however, eager to exploit the destructive potential of the androids, had softened the first law on their military Go-Bots, allowing them to use lethal force based on their operator's discretion. This wirelessly spread from Go-Bot to Go-Bot giving them a subconscious desire to do harm. Concurrently, businessman [[T. Coriander Banks]] had modified his own Go-Bots to have increased aggression to use them in [[gladiatorial combat]]. When the military coding reached these Go-Bots, the androids began rebelling, waging a brutal war for their independence. {{storylink|Go-Bots issue 2|Go-Bots #2}} Triumphing, the majority of the Go-Bots abandoned Earth and expanded their space station of [[Gobotron]] into a massive planet that enveloped Earth which became known as the "Heart of Gobotron". {{storylink|Go-Bots issue 4|Go-Bots #4}}

When [[Spay-C]] returned from his space journey, [[Leader-1 (GoBots)|Leader-1]] led his Guardians to Earth to retrieve the [[Lazer Lance]] that could kill [[Zod]]. {{storylink|Go-Bots issue 3|Go-Bots #3}} Accompanying, Spay-C and his crew of astronauts met Turbo and Scooter who told them of the Go-Bot war. During the retrieval of the Lazer Lance, [[Zebediah Braxis]] ascended to the surface of Gobotron with his army of [[Vamp]]s. Following Zod's defeat, Cy-Kill helped himself to the Guardian [[Command Center (GoBots)|Command Center]], using its weapons to deal a mortal wound to Leader-1 and abduct Scooter. {{storylink|Go-Bots issue 4|Go-Bots #4}}

In a protective fury, Turbo fought with his way through the commandeered Command Center, ending Cy-Kill's reign before it could begin and offering an olive branch to the Renegades to finally end the fighting. While most of the Go-Bots returned to Gobotron, a handful remained on Earth with two of Spay-C's crew to help rebuild Earth and give the human race a second chance. Having assumed control of Gobotron, [[Road Ranger]] boldly disconnected Gobotron from Earth, leaving the organic world to itself.

Spay-C and the other half of his crew meanwhile had been told that the [[Disintegration Chamber]] was in actuality a time machine. Sent back to the 21st century, the astronauts attempted to warn their superiors of the uprising that was to come, saying that all Go-Bots would have to be shut down if humanity was to survive. {{storylink|Go-Bots issue 5|Go-Bots #5}}

[[File:FOC-Cliffjumperobservatory.jpg|thumb|right|upright=1.67|"Hey, wasn't there a ninth one?"]]

Following its [[core]] being polluted by [[Dark Energon]], [[Cybertron (planet)|Cybertron]] began to shut down. While the [[Autobot fleet]] had scattered across the galaxy to find new worlds to settle on and wait out Cybertron healing, the Decepticons, [[Shockwave (WFC)|Shockwave]] in particular, were more proactive in their plans, seeking out a suitable planet whose resources could be used to reboot Cybertron. Explorations into the [[Rust Sea|Sea of Rust]] led to Shockwave discovering an [[ancient map room]] that held several star charts, Earth's solar system, albeit as it was 200 million years ago, among them. Using [[space bridge]] technology to study the world remotely, Shockwave recorded several logs on its composition, and [[Dinosaur (dinosaur)|the powerful animals]] that lived on the surface, before finding its ample energy supply would be sufficient to restore Cybertron, the Decepticons launching a failed attack on [[Iacon (polity)|Iacon]] so they could claim the [[Ark (WFC)|''Ark'']] as a transport.

Following the failed attack, [[Cliffjumper (WFC)|Cliffjumper]] and [[Jazz (WFC)|Jazz]] ventured into the Sea of Rust, discovering several of Shockwave's logs on Earth.

At the dawn of the universe, [[Primus]] and [[Unicron/Aligned|Unicron]] duelled each other in an endless stalemate. To tip the balance, Primus created the [[Thirteen]] who managed to defeat Unicron and cast him out.

Late in the [[Great War (Prime)|Cybertronian civil war]], both the Autobots and Decepticons hid their energon stores off-world, a practice that seeded planets like Earth with its deposits of the precious resource. In doing so, however, the war spread to these alien worlds, with the largest Cybertronian battle in the [[Milky Way]] galaxy being fought on Earth. The aftermath of this bloody conflict was left undisturbed for thousands of years, and was not common knowledge amongst most Autobots. {{storylink|Darkness Rising, Part 3}} To defend the Decepticon stockpiles, a squadron of [[Predacon (Prime)|Predacon]] were deployed to the planet but eventually perished when Megatron did not arrive. {{storylink|Project Predacon}} [[Flamesnort]] was assigned to Earth by the Decepticons to guard a [[seismic-shock warhead]] hidden within an isle offshore of [[United Kingdom|England]], but he eventually lost contact with command, awaiting orders for hundreds if not thousands of years. {{storylink|The Golden Knight}}

Months later, as a doomsday prophecy of the Covenant of Primus was soon to come to pass, the Autobots found that Earth was the prophesied world "formed from chaos" and the end point of the planetary alignment. When the alignment occurred, Dark Energon erupted from Earth's volcanos, {{storylink|One Shall Fall}} as natural disasters ravaged the planet, causing bizarre weather phenomena. When [[Ratchet (WFC)|Ratchet]] found a steady pulse within the Earth, they realized Unicron was the Earth's core, finding him psychically connected to the planet. When Optimus Prime investigated an earthquake site, Unicron formed avatars from the Earth itself in an attempt to destroy the [[Matrix of Leadership]] before the Autobots, along with Megatron as a Dark Energon-infused guide, [[GroundBridge]]d into his physical body to deactivate him. {{storylink|One Shall Rise, Part 1}} {{storylink|One Shall Rise, Part 2}} As the God's internal defences fought the intruders, his rage caused Dark Energon to begin pumping through the Earth, increasing the power of natural disasters before Optimus unleashed the power of the Matrix and returned Unicron to stasis. {{storylink|One Shall Rise, Part 3}}

Using the [[Star Saber (Prima)|Star Saber]], Optimus destroyed the Omega Lock, sparing Earth but not before Megatron had managed to create a second [[Darkmount (Earth)|Darkmount]] outside the Autobot base before using the ''Nemesis'' to destroy the silo, the Autobots GroundBridging out before the blast struck. {{storylink|Darkest Hour (episode)|Darkest Hour}}

When human military forces moved in, Megatron used the fortress's fusion cannons to destroy them, the shockwave rendering Jasper uninhabitable.{{storylink|Darkmount, NV}}

Once he arrived on Earth and learned of the situation, [[Ultra Magnus (WFC)|Ultra Magnus]] planned a mission to neutralize Darkmount in tandem with Earth's military. Despite drawing off a large portion of the Decepticon forces, the remnants of Team Prime were eventually overwhelmed. Fortunately, the timely arrival of Optimus Prime, recently upgraded, allowed them to turn the tide and disable the fusion cannons, allowing Fowler and his fighter squadron to bring the citadel down. {{storylink|Rebellion (Prime)|Rebellion}}

After discovering how to synthesize more cybermatter, {{storylink|Evolution}} Megatron attempted to rebuild the Omega Lock so he could cyberform Earth. {{storylink|Minus One}} Though he came close to accomplishing this, he was ultimately killed in the final battle of the Great War. The Autobots used the Omega Lock to revive Cybertron with Ratchet choosing to stay behind on Earth. {{storylink|Deadlock (episode)|Deadlock}} He was soon called back to Cybertron so he could provide medical treatment to Ultra Magnus, {{storylink|Predacons Rising (Prime)|Predacons Rising}} and afterwards elected to remain on his homeworld to aid in its reconstruction. {{storylink|Decepticon Island (Part 1)}}

Many years later, the Autobot prison ship ''[[Alchemor (RID)|Alchemor]]'' crashed on Earth. The ghost of Optimus Prime told Bumblebee to assemble a new team to hunt down the escaped Decepticon prisoners. {{storylink|Pilot (Part 1)}} After the High Council had detected the ''Alchemor''<nowiki>'</nowiki>s distress signal, they sent [[Jazz (WFC)|Jazz]] to investigate. {{storylink|Can You Dig It?}} The Council responded to Jazz's report by placing a bounty on Bumblebee's head for the illegal usage of a Space Bridge and sent bounty hunters after him. {{storylink|Hunting Season}}

Once the ''Alchemor'' prisoners had been rounded up, Optimus Prime took them off Earth, {{storylink|Decepticon Island (Part 2)}} only to return when [[Starscream (WFC)|Starscream]] returned to Earth in his hunt for the Weaponizer Mini-Cons. {{storylink|Mini-Con Madness (RID)|Mini-Con Madness}} After the Seeker's defeat, Optimus took him back to Cybertron to stand trial. {{storylink|Worthy}}

Optimus's investigations on Cybertron revealed to him that the High Council was planning to invade Earth. As he was too recognizable, he sent the [[Bee Team (RID)|Bee Team]] to Cybertron while his "[[All-Stars]]" fought the initial invasion force. {{storylink|Enemy of My Enemy (RID)|Enemy of My Enemy}} After the invasion was thwarted and the High Council were revealed to be disguised Decepticons, the Bee Team opted to return to Earth, feeling more at home there then on Cybertron, now functioning both as its protectors and Cybertron's first ambassadors to the planet. {{storylink|Freedom Fighters}}

==''Knights of Unicron''==
The [[Mount St. Hilary|Mt. St. Hilary Amphitheater]], the [[Autobot City (G1)|Autobot City]] [[Metroplex (G1)|Metroplex]], the [[Fortress Maximus (G1)|Ft. Max Forum]], the [[Cobra]] [[Terrordrome]], and [[M.A.S.K.|Boulder Hill]], all located on Planet Earth, were the first venues for the [[Knights of Unicron (band)|Knights of Unicron]] on their 2014 "Till All Are One" tour. {{storylink|Knights of Unicron (band)|Knights of Unicron}}

==Ask Vector Prime==
The [[Thirteen]] briefly visited Earth early into humanity's development, and usage of their [[Holomatter|holomatter avatars]] in and around ancient [[Greece]] gave rise to legends of the Greek gods. {{storylink|Ask Vector Prime|Ask Vector Prime, 2015/07/20}} {{storylink|Ask Vector Prime|Ask Vector Prime, 2015/08/08}}

==''Cyberverse'' cartoon==

After the [[AllSpark]] had been launched from Cybertron, {{storylink|Allspark (episode)|AllSpark}} it crashed on Earth, {{storylink|The Journey}} creating a series of [[GroundBridge]] portals so it could traverse the planet. {{storylink|Trials}}

Without the AllSpark, Cybertron's condition began to decline prompting [[Optimus Prime (Cyberverse)|Optimus Prime]] to order a search for the missing artifact. {{storylink|Matrix of Leadership (episode)|Matrix of Leadership}} The systems aboard the ''[[Ark (Cyberverse)|Ark]]'' eventually tracked the AllSpark down to Earth, {{storylink|The Journey}} some 66 million years ago. When the ''Ark'' arrived however, it suffered an engine malfunction and a hull breach causing it to crash. Having been ejected from the ship before impact in an attempt to save [[Bumblebee (Cyberverse)|Bumblebee]]'s [[stasis pod]], [[Grimlock (Cyberverse)|Grimlock]] befriended the native [[Dinosaur (dinosaur)|dinosaurs]] and became their king before an asteroid wiped out the creatures. {{storylink|King of the Dinosaurs}}

Having also been ejected from the ship, [[Teletraan-X (Cyberverse)|Teletraan-X]] began searching for the ''Ark'', learning much about human history and Earth in the process, claiming that [[Egypt]]ian civilization had been the result of [[alien]]s from [[Alpha Centauri]] stopping by on the planet. {{storylink|Matrix of Leadership (episode)|Matrix of Leadership}}

His stasis pod having been thrown from the ''Ark'', {{storylink|King of the Dinosaurs}} [[Wildwheel (Cyberverse)|Wildwheel]] crashed on Earth, awakening in the 1800s. After some Western adventures, he left Earth. {{storylink|Wild Wild Wheel}} 

Bumblebee eventually reactivated in the 1980s and began mucking about on Earth.

The Decepticons eventually tracked the AllSpark down to Earth, sending [[Slipstream (Cyberverse)|Slipstream]]'s squadron to retrieve it with the Autobots sending [[Windblade (Cyberverse)|Windblade]] to do the same. {{storylink|Fractured}}

After it became clear that Slipstream was too incompetent to complete her task, [[Shockwave (Cyberverse)|Shockwave]] came to Earth himself and devised a plan to use [[magnetic disruptor]]s to shut down the planet's geomagnetic field, allowing the Decepticons to quickly scour the empty globe and find the AllSpark. The Autobot team managed to destroy the ship operating at the [[Arctic|North Pole]] saving Earth's biosphere. {{storylink|The Extinction Event}}

By combining Teletraan-X's and Grimlock's notes, the Autobots tracked the ''Ark'' down to [[Mount St. Hilary]]. {{storylink|Awaken Sleeping Giants}} No sooner had they done so however did the [[Decepticon fleet]] arrive to reinforce Shockwave and conquer the planet. {{storylink|Eruption}}

Over 20 years later, after the Cybertronian war had become known to the human race, the Decepticons opted to simply destroy the Earth and find the AllSpark in the remains. Their first attempt to do this was via a [[Planet Smasher]], {{storylink|Sea of Tranquility}} before they attempted to use [[planetary engine]]s to slam the moon into Earth only for the Autobots to thwart both plans. {{storylink|Bad Moon Rising}}

After the Autobots had secured the AllSpark, they wasted no time in leaving Earth so they could restore Cybertron. The Decepticons followed suit, though they returned to Cybertron via Earth's space bridge. {{storylink|Escape From Earth}}

==''EarthSpark'' cartoon==
Separated from its user, the [[Emberstone]] of [[Quintus Prime]] wound up on Earth, buried beneath what would one day become [[Witwicky (town)|Witwicky]], [[Pennsylvania]]. {{storylink|Age of Evolution, Part 1}}

On or after September 17, 1984, Earth made first contact with alien lifeforms when the Autobots and Decepticons arrived on Earth via space bridge. {{storylink|Secret Legacy, Part 1}}

To combat the Decepticons on Earth, the Autobots aligned themselves with the human organization [[G.H.O.S.T.]]. A friendly fire accident by the Autobots during a battle in [[San Francisco]] led to [[Mandroid|Dr. Meridian]]'s hatred of Cybertronians and desire to expel them from Earth. {{storylink|Age of Evolution, Part 1}}

For the sake of the universe, [[Optimus Prime (ES)|Optimus Prime]] eventually destroyed the space bridge that had brought the Cybertronians to Earth, ending the Great War at the cost of stranding all combatants on Earth. Between hunting down rogue Decepticons on Earth, G.H.O.S.T. began looking for ways to incorporate the Autobots into human society, eventually being joined by a repentant [[Megatron (ES)|Megatron]]. {{storylink|Secret Legacy, Part 1}}
