Earth

Mostly harmless.

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 humans. 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 Transformers. Perhaps too frequently. Whenever someone or something leaves, escapes, or is otherwise ejected from 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".

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 becomes the post-apocalyptic planet Gaia, while in others, Earth is the planet that formed around Unicron or the goddess Gaea, furthering Earth's connection to Cybertron, which is (usually) the body of Primus. In one universe, the Earth itself is a Transformer known as Atlas.

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 dinosaurs still lived.

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

In the year 1017 AD, the Autobot Navigator and his companion arrived on Earth in search of the lost Ark. Their ship landed near the town of Stansham, 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." Man of Iron

The outbreak of the Korean War in the 1950s saw the United States of America embroiled in the conflict, with Irving Witwicky serving with the United States Marine Corps during the war. The Last Stand

By the 1980s, Earth was involved in a 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 organisation Blood on the Tracks and/or the international Action Force Ancient Relics! (sources 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. Prisoner of War!

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 RAAT. Diplomatic relations were tried early on with the President of the United States, but failed.

Following the disappearance of this universe's version of Galvatron, however, the people of Earth were able to stage a successful uprising against their Decepticon conquerors, and the 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's Cybertronian Empire.

After the Ark crashed on Earth for a second time, the crash site was patrolled by Spike Witwicky and 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 with Megatron being reactivated.

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 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's Decepticon Syndicate or to UK citizen Pyro's Autobots.

In 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.

In the distant past, at the height of the Great War, the starship Ark crash-landed on Earth, buried beneath Mount St. Hilary for millions of years. 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, Other Voices, Part 1 erecting mysterious constructions at strategic intervals, such as a floating "island" The Trigger, Part 1 and the standing stones, designed to attract and study any intelligent lifeforms on the planet. Chain of Command As a failsafe, the Vok installed an artificial second moon over the planet, a 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 criminal Megatron was able to steal a Golden Disk, which contained a hidden message left behind by the original Megatron. Aware that the recent invention of transwarp technology would enable Cybertronians to 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. The Agenda (Part 2) 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. Deep Metal

And scientists cried in frustration.

Though pursued by a group of Maximals, Megatron's stolen ship and the Maximal vessel 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 modes to protect themselves from energon radiation, the two sides waged a conflict they dubbed the "Beast Wars," Beast Wars (Part 1) Beast Wars (Part 2) and accidentally alerted the Vok to their presence after stumbling into one of their many sites.

Deciding that the Beast Warriors had contaminated their experiment, the Vok activated the second moon and began their sterilization protocol.

Around this time, the Dinobots pursued the Insecticons 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. 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 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. 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. 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.

Revelation

"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 Keepers,) 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. New World Order

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

G.I. Joe vs. the Transformers

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 during the zenith of their reign, the people of Cobra-La cut a deal: in exchange for them not deploying their virulent metal-eating fungus against him, Unicron would depart and return in a few thousand years, when humanity 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. 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. 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. G.I. Joe vs. the Transformers issue 5

Two years after the Autobots and the members of the newly-minted 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. G.I. Joe vs. the Transformers II #1

A time-hopping adventure ensued as both Cobra and Joe members travelled through Earth's history; beginning in the mid-1970s, G.I. Joe vs. the Transformers II #1 then to Chicago in 1937, 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. G.I.

In the meantime, US scientists worked to develop a sentient Earth defense system using Cybertronian technology, but the end result was the malevolent Serpent O.R., The Art of War #1 who swiftly launched an attack on Cybertron. 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. 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 and 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.

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. 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.

Roughly seven to eight million years ago, at the conclusion of the First Cybertronian Civil War, the barbarian warrior Galvatron launched the Enigma of Combination into space, and by pure coincidence this artifact would eventually fall to Earth. The Crucible

During the Great War between the Autobots and Decepticons, the Decepticon scientist 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. 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. 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 Metrotitan across time and space, eventually burying him beneath Monument Valley so that Optimus Prime would find him. The Hallowing

In the meantime, "Onyx" sent a crew of Maximals out into the universe aboard the starship Axalon, ostensibly to recover the Enigma of Combination. 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 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. Strange Visitors Shockwave, however, had been tailed by the Dynobot tactical unit, and both they and Shockwave were left buried in a volcanic eruption. Spotlight: Shockwave The lost Maximals retreated underground and entered hibernation. Strange Visitors

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.

Another unauthorised landing, this time by the rogue 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. Infiltration #4

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, followed them in an attempt to thwart their aims. Decepticon agents were placed in multiple areas, such as the United States government and the separatists of Brasnya. However, the recent discovery of Ore-13 by Starscream's team prompted the treacherous lieutenant to break protocol in an effort to rebel against Megatron. Autobot agent Ratchet also broke protocol by initiating direct contact with three humans, who proved invaluable in gaining intelligence on Starscream's operations. 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. Escalation Devastation

About a year on from this, everyone suddenly forgot they knew about the Transformers, while a disgruntled 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 and put a stop to that. All Hail Megatron

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.

A great body of evidence suggested that the histories of Earth and 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 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. Conversely, Galen's existence implied that humans had somehow arose on, or migrated to, Cybertron during some prior era. Expelled from the Garden

I Saw Three Ships Under his control, Cybertron was made to collide with Earth, Pax Megatronus which was presumed destroyed by those on Cybertron when space dust and debris covered the metallic world. 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 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.

In the distant past, the Earth formed around the inert body of Unicron, the Chaos Bringer. The Last Knight

65 million years ago, a mysterious race known only as the Creators came to Earth with plans to cyberform it using the Seeds. 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 transformium - the Creators then left Earth, allowing its organic life to take over once again. Age of Extinction

And this is... erm... well, I can't tell. But it's exciting, honest!

In 17,000 B.C.E., the Thirteen Seven founders of the Dynasty of Primes came to Earth with their warriors and workers to build a Harvester unit, designed to nick power from stars to charge the mighty 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 activate the harvester, and hid it in a tomb made of their bodies. The harvester was abandoned on Earth, in the country that would be called Egypt. The native humans built a pyramid around it, millennia before those Ivory Tower eggheads claim the Egyptians did. Seekers would start searching the planet for the Matrix, and symbols and pictures of them ended up on ancient human relics. Revenge of the Fallen

The AllSpark itself crashed onto Earth around 10,000 B.C.E., followed a few thousand years later by the Transformer Megatron who would become buried at the Arctic Circle. The discovery of the latter would lead to the formation (at ...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. Unknown to Sector Seven (initially), the Seekers were still searching on Earth, this time disguised as contemporary machinery; one of them would accidentally cause the Spanish-American War.

Tekeli-li!

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.

Through Megatron, much of modern human technology would be created via reverse-engineering and much of modern American history driven by Sector Seven. Oppenheimer created the atom bomb through reverse-engineered technology; the "space race" (including more secret parts of it) was won by America solely due to Megatron's bits; and Three Mile Island was caused by poking at the AllSpark. The Soviet Union was aware of Sector Seven and its "Ice Man", and attempted to capture it when it was transported from the Arctic to America.

The 1980s would see a number of Transformers landing on Earth, including Starscream, before soon departing. This appears to have been covert even among their own factions, as none of the Transformers have referred to it. Sector Seven hurriedly initiated the Hungry Dragon black propaganda operation, creating a toyline of transforming robots to cover up the sightings.

By the 21st century, the United States had thus become so powerful the United States military possessed bases in foreign countries such as Qatar and NASA had total supremacy over space-related matters. Sector Seven had its own paramilitary wing and prisons, all while being so secret the Secretary of Defence was unaware of its existence.

What the hip kids will wear in the far future of 2007.

In 2003, covert Transformers (both Bumblebee and Decepticon) arrived on Earth to search for the AllSpark, successfully evading and sometimes killing any Sector Seven forces. Another and seemingly unrelated faction would later attempt the same thing, even getting their operative Dewbot inside the Hoover Dam base. Operating at the fringes were human vigilantes such as the mysterious Agent X and the Lunchables Brigade paramilitary, the latter having some form of contact with the Autobots.

In the summer of 2007, the same Decepticons arrived on Earth again and would learn of the existence of Archibald Witwicky's glasses, upon which the physical location of the AllSpark was imprinted; luckily, 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 two youths. Transformers

"And to my opponents on this issue, I'd like to say pbbbbbt suck it!"

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, only to end up in the shit after their secret Decepticon prisoner was activated and caused a major battle. The same day, the Nemesis, a long lost Decepticon ship tasked with locating Earth, arrived in Earth's solar system; its commander Soundwave, upon learning of the loss of Megatron and the Cube, dispatched forces across the planet to begin looking for Megatron's body and the Matrix of Leadership.

Following this, Sector Seven was shut down and a secret military alliance was made between the United States and the Autobots: NEST. Other countries were involved with NEST, but it's not clear how heavily they were. Either way, they had repeated battles with rogue Decepticons.

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 its cities; Egypt and Jordan had established a border with each other; and a large number of bloggers were aware something was being covered up, with a possibly-new Agent X passing information to them. 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. Revenge of the Fallen

By this time, Earth's main export was ex reality-TV contestants. Welcome to Earth

Post-Fallen, Autobot/NEST forces would have multiple battles with leftover Decepticon forces and human factions. They would also uncover the lost Power Core Combination technology on Earth, causing an escalation on both sides as combiner technology was applied. Cyber Missions

A few years after the death of the Fallen, the Autobots and Decepticons were public knowledge and energon detectors 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 pillars and 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. 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. Dark of the Moon

When 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. The Last Knight

Titan alternate timeline

The following events occur in a splinter timeline where Megatron won the battle of Mission City.

In a further 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 Paris, including the loss of the French centre of government.

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, but the fundamental damage was already done: Earth's core was infected, causing the planet to be torn apart by continuing techno-organic activity. Unnatural 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.

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. To make matters worse, the Decepticons had mental control over hundreds of human officials, including 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.

Live-action film series games

There are several divergent timelines where the presence of other Transformers or different strategies undertaken altered the entire pattern of events.

Some have the same basic outcome, but with greater and more wide-ranging devastation to America and greater (but futile) resistance by Sector Seven. At least one resulted in not only wider destruction but in complete Decepticon victory.

In the most severe divergence, the rogue Decepticon general Mainframe reached Earth before the Autobots and established an army and base at the Arctic. He began taking out every Autobot agent arriving on Earth, whilst searching for the AllSpark, and eventually began sweeping the Earth with large numbers of drone units. He was eventually defeated by the Earthbound Chevy Autobots unit; the impact this had on Starscream's attempts to gain the AllSpark, not to mention Earth itself, are unknown.

Bumblebee film

Once Cybertron had fallen to the Decepticons, Optimus Prime dispatched B-127 to Earth so he could establish a base. When the scout arrived, he was attacked by Blitzwing, his injuries resulting in amnesia. When Shatter and Dropkick captured and interrogated B-127, they learnt Optimus Prime was planning to use the Earth as a resistance base prompting them to try and summon the Decepticon fleet and 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 arriving on Earth.

Cybertronian legend tells of an ancient, eons-raging battle between Primus and Unicron. After Primus had cast Unicron into space by creating the thirteen original Transformers, Unicron slumbered for many ages. In his slumber, debris gravitationally attached to Unicron formed the planet Earth, of which Unicron is its core. One Shall Rise, Part 1

Late in the 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. Darkness Rising, Part 3

As Cybertron began to shut down to purge the Dark Energon corruption, the scientist Shockwave began using space bridge technology to try and find a large cache of energon that could be used to prematurely reboot Cybertron. His quest eventually brought him to Earth, where the dominant life-forms inspired him to experiment on four captive Autobots, producing the Dinobots. Transformers: Fall of Cybertron

Following Optimus Prime and Megatron's initial skirmishes on the planet, the former ordered all Autobots to Earth, while Starscream was sent to salvage a space bridge from wherever he could find it. Transformers: Prime The Autobots, meanwhile, set up Autobot Outpost Omega One in an American missile base and opened up relations with the United States government: Special Agent Fowler of the Pentagon was assigned as their liaison. Darkness Rising, Part 2

Starscream built his space bridge to bring Decepticons to Earth, but Arcee and Cliffjumper sabotaged it; only Starscream came through. On Earth, Starscream rendezvoused with Breakdown to assault the two saboteurs, but Optimus and Bumblebee rescued them. Returning to base via a GroundBridge, Optimus informed Cliffjumper more Autobots were gathering, and the battle had only begun. Transformers: Prime The Autobots would covertly watch for Decepticons, while the 'cons covertly mined energon. Darkness Rising, Part 2

The Covenant of Primus tells of an eternal conflict caused when certain planets come into alignment. The Autobots figured out that Earth was the planet that was prophesied as chaotically formed, as did Megatron. During Optimus Prime's one-on-one battle with Megatron, the volcano setting erupted with Dark Energon, right when the planetary alignment as predicted came to pass. One Shall Fall Earthquakes and tornadoes hit across the planet right after the volcanic event. It was soon determined that this weather phenomena was caused by the awakening of Unicron. Optimus Prime theorized that after Unicron was defeated by the thirteen original Primes, his dormant form collected space matter, which eventually formed into the planet Earth. Optimus Prime also theorized that Unicron became formless during that time. At least, he hoped Unicron became formless. Otherwise, if he woke up and stretched, KAPOW! Earth would poof to dust. One Shall Rise, Part 1 The strange weather events ended when Optimus Prime used the Matrix of Leadership to force Unicron into stasis. One Shall Rise, Part 3

After activating the Omega Lock, Megatron directed a shaft of energy through a space bridge, striking Earth near Jasper and creating a huge Cybertronian fortress. Agent Fowler had the town evacuated as a result. Optimus used the Star Saber to destroy the Omega Lock, saving Earth in the process. However, when the Decepticons returned to Earth, Megatron dubbed this fortress New Kaon before proceeding to destroy the nearby Autobot base. Darkest Hour

When human military forces moved in, Megatron used the fortress's fusion cannons to devastate both them and most of Jasper. He had also by that time decided to call the fortress Darkmount. The Decepticons moved in shortly afterward. Darkmount, NV Smokescreen infiltrated the base using the phase shifter in an attempt to find the Forge of Solus Prime, which turned out to be stored aboard the Nemesis. Prey

Once he arrived on Earth and learned of the situation, 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. Rebellion

After discovering how to synthesize more cybermatter, Evolution Megatron attempted to rebuild the Omega Lock so he could cyberform Earth. 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. Deadlock He was soon called back to Cybertron so he could provide medical treatment to Ultra Magnus, Predacons Rising and afterwards elected to remain on his homeworld to aid in its reconstruction. Decepticon Island (Part 1)

Many years later, the Autobot prison ship Alchemor crashed on Earth. The ghost of Optimus Prime told Bumblebee to assemble a new team to hunt down the escaped Decepticon prisoners. Pilot (Part 1) After the High Council had detected the Alchemor's distress signal, they sent Jazz to investigate. 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. Hunting Season

Once the Alchemor prisoners had been rounded up, Optimus Prime took them off Earth, Decepticon Island (Part 2) only to return when Starscream returned to Earth in his hunt for the Weaponizer Mini-Cons. Mini-Con Madness After the Seeker's defeat, Optimus took him back to Cybertron to stand trial. 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 to Cybertron while his "All-Stars" fought the initial invasion force. 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. Freedom Fighters

Knights of Unicron

The Mt. St. Hilary Amphitheater, the Autobot City Metroplex, the Ft. Max Forum, the Cobra Terrordrome, and Boulder Hill, all located on Planet Earth, were the first venues for the Knights of Unicron on their 2014 "Till All Are One" tour. Knights of Unicron

Ask Vector Prime

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

Cyberverse cartoon

These are the voyages of the spaceship Entire Prize.

After the AllSpark had been launched from Cybertron, AllSpark the planet's condition began to decline prompting Optimus Prime to order a search for the missing artifact. Matrix of Leadership The systems aboard the Ark eventually tracked the AllSpark down to Earth, 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's stasis pod, Grimlock befriended the native dinosaurs and became their king before an asteroid wiped out the creatures. King of the Dinosaurs

Having also been ejected from the ship, Teletraan-X began searching for the Ark, learning much about human history and Earth in the process, claiming that Egyptian civilization had been the result of aliens from Alpha Centauri stopping by on the planet. Matrix of Leadership

Bumblebee eventually reactivated and began mucking about on Earth.

The Decepticons eventually tracked the AllSpark down to Earth, sending Slipstream's squadron to retrieve it with the Autobots sending Windblade to do the same. Fractured

After it became clear that Slipstream was too incompetent to complete her task, Shockwave came to Earth himself and devised a plan to use magnetic disruptors 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 North Pole saving Earth's biosphere. The Extinction Event

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