Taking place directly after the [[Age of Rust]], the '''Great War''' was a violent outburst of fighting on the planet [[Cybertron (planet)|Cybertron]], between the newly christened [[Autobot]]s and [[Decepticon]]s. After cycles of social stratification caused by the [[Functionism|caste system]], the bloated bureaucracy established during the [[Age of Wrath]], and the trauma of the [[Cosmic Rust (disease)|Rust Plague]], two prominent individuals emerged in Cybertronian politics: a gladiator named [[Megatron (WFC)|Megatron]] from [[Kaon (polity)|Kaon]] and an archivist from the [[Iacon (polity)|Iacon]] [[Hall of Records]] named [[Optimus Prime (WFC)|Orion Pax]]. While initially working together, Orion's ascension as Optimus Prime led to the two forces fighting for several million stellar cycles. Although the two warring factions would temporarily come together to face a common threat, such as the [[Quintesson|Quintessons]] and [[Unicron/Aligned|Unicron]], these truces were often short-lived.

The Great War can be divided into four distinct eras: 
*The '''War on Cybertron'''
*The [[Great Exodus]], or the '''Fall of Cybertron'''
*The War Across the Stars (as depicted in ''' ''Transformers: Exiles'' '''and ''' ''Transformers: Retribution''''')
*The War on Modern-Day Earth (as depicted in ''' ''Transformers: Prime''''')

[[File:DarknessRising2-Megsflashback.jpg|thumb|right|200px]]
The war quickly spreads beyond the High Council, and before long battle lines are drawn as various city-states declare their allegiances. Autobots and their allies control the most important locations on Cybertron, including [[Iacon (polity)|Iacon]] and [[Kalis]]. Shortly after the declaration of war, the Allspark stops producing new Cybertronians; some interpret this as an act of divine rebellion. Undeterred, the Decepticons launch their first strike by seizing [[Fort Scyk]]. [[Ultra Magnus (WFC)|Ultra Magnus]] and his Council Guardians manage to hold the line long enough for the Autobots to send reinforcements. The Decepticons then attack and occupy the [[Hydrax Plateau]]. With this crucial region under Decepticon control, Megatron quickly takes over the majority of Cybertron's eastern hemisphere, which remains in Decepticon hands for the majority of the war. Decepticons then capture the [[Satellite Command Center]] at [[Polyhex]]. The battle of [[Crystal City]] sees the [[Constructicon (WFC)|Constructicons]] deploy their combined [[Devastator (WFC)|Devastator]] against the Autobots, razing the city. Many of its scientific treasures survive the destruction. {{storylink|Transformers: Exodus|Exodus}} Many dangerous weapons, such as the [[Cybonic plague]], are developed by the [[Decepticon Biological Warfare Program]]. {{storylink|Sick Mind}}

The Autobots win their first major victory at [[Kalis]], where Optimus Prime, Sideswipe, and Jazz topple the Decepticon [[combiner]] [[Bruticus (WFC)|Bruticus]]. Kalis remains in Autobot hands and the Autobots begin using long-range combat against Decepticons. Shockwave's armies occupy the cities of [[Tarn (polity)|Tarn]] and [[Vos (polity)|Vos]]. Shockwave manipulates the two cities and turns them against one another, destroying them both. The Decepticon campaign reaches [[Praxus]], where they encounter stiff Autobot resistance. The city-state is ultimately leveled by the fighting, and to this day the outcome is unclear. [[Prowl (WFC)|Prowl]] and [[Ironhide (WFC)|Ironhide]], citizens of Praxus, join the Autobot cause and become part of Optimus Prime's inner circle of confidants. {{storylink|Transformers: Exodus|Exodus}} 

Megatron, still stinging from the loss of Praxus, orders Bruticus Maximus to spearhead a massacre at [[Nova Cronum]]. In the meantime, Minicon saboteurs manage to steal and reverse-engineer Shockwave's secrets, and before long the Autobots create their own combiners. {{storylink|Transformers: Exodus|Exodus}} Optimus Prime assigns Ultra Magnus to lead the unruly squadron known as the [[Wreckers]] in the hopes of instilling discipline into their ranks {{storylink|Project Predacon}}, and with the aid of the newly created [[Defensor (WFC)|Defensor]] the team defends the Tagan Heights against the Constructicons, although the fighting between Defensor and Devastator demolishes the area. {{storylink|Transformers: Exodus|Exodus}} 

At some point during the war, Optimus Prime survives an assassination attempt by [[Skyquake (Prime)|Skyquake]] at the [[Battle of Technahar]]. {{storylink|Masters & Students}}

After centuries of stasis, the [[AllSpark]] creates a final generation of Transformers, most of whom side with the Autobots. Among them is the Autobot [[Bumblebee (WFC)|Bumblebee]], who distinguishes himself on the battlefield and becomes one of Optimus Prime's closest compatriots. {{storylink|Transformers: Exodus|Exodus}} Another young Autobot named [[Smokescreen (Prime)|Smokescreen]] enters the boot camp of the Elite Guard with hopes of becoming a full-fledged soldier. {{storylink|New Recruit}} 

[[Arcee (WFC)|Arcee]] and her combat partner [[Tailgate (Prime)|Tailgate]] serve in [[Delta Team]] for most of the war. After a raid on a Decepticon munitions depot, both of them are captured and interrogated by the Decepticon [[Airachnid (Prime)|Airachnid]]. Although Arcee is rescued by Bumblebee and [[Cliffjumper (WFC)|Cliffjumper]], they are too late to save Tailgate. {{storylink|Predatory}} At least some battles take place off Cybertron with the [[Wreckers]] having an adventure on [[Sandokan]]. {{storylink|Loose Cannons}}

As the war continues, the Autobots are gradually outnumbered and outgunned. Optimus Prime makes the painful decision to eject the AllSpark from Cybertron, so that Megatron cannot create more Transformers. In the ensuing battle, the Allspark is fired into deep space from [[Tyger Pax]]. {{storylink|Transformers: Exodus|Exodus}} The Autobots also decide to eject the data cylinders from Cybertron to prevent Decepticons from using the vital knowledge within. {{storylink|T.M.I.}} With the Allspark gone, the Decepticons focus their attention on Iacon, one of the last regions still under Autobot control.

At some unspecified time, Primus warned [[Windblade (RID)|Windblade]] of a rising evil, and sent her to Earth after modifying her body and enhancing her sensors. {{storylink|The Buzz on Windblade}}

Seeking a new edge in the war, Megatron storms Trypticon Station and wrests control of it from [[Starscream (WFC)|Starscream]], empowering himself and other Decepticons with the Dark Energon stored there. As part of their next strike, the Decepticon-allied Seekers travel deep underneath Cybertron in search of the long-abandoned [[Geosynchronous Energon Bridge]] beneath the ruins of Crystal City, which will allow the manufacture of new Dark Energon for the Decepticons' use. 

Megatron leads a group of Decepticons into Iacon, to find a means of travelling to the very core of Cybertron to spread the Dark Energon. Though Sentinel Prime attempts to stand in his way, he is soon defeated by the vengeful Decepticon—but unbeknownst to Megatron, [[Omega Supreme (WFC)|Omega Supreme]] is reactivated due to these events, and is intent on stopping the Decepticons. The Decepticon forces manage to cripple the Guardian's alternate mode, and Megatron and his troops soon defeat him on ground level. Because of this, the Decepticon leader manages to reach Cybertron's core and corrupt it with Dark Energon—a critical blow against the Autobots. {{storylink|Transformers: Exodus|Exodus}} {{storylink|Transformers: War for Cybertron (360/PS3/PC)|War For Cybertron}}

The Autobots, however, are not yet defeated, and muster a counter-attack to rout the remaining Decepticons from Iacon. Sentinel, now imprisoned in Kaon, is able to send a transmission, and a small group of Autobots, lead by Optimus, soon launch an incursion into the prison to recover him. However, the former Prime perishes just as he has been rescued. The Autobots return the body to Iacon, and Optimus officially comes to accept that he is a Prime and must take up his role as leader. From then on, he fully becomes known as Optimus Prime, the last of the Primes. Optimus's first task as true Prime is to cleanse the infected core. Heading down through Cybertron's inner layers, Optimus finds much of the planet is thoroughly infected by Dark Energon. The core tells Prime that Cybertron is so greatly corrupted that it will take millions of years of shutdown in order to undo the grievous damage done by Megatron's Dark Energon. Optimus is given the [[Matrix of Leadership]] by the Core, a fragment of [[Prima]]'s powerful sword that contains a portion of Cybertron's spark. {{storylink|Transformers: Exodus|Exodus}} {{storylink|Transformers: War for Cybertron (360/PS3/PC)|War For Cybertron}}

With the core's shutdown, Windblade is left in stasis on Earth. {{storylink|The Buzz on Windblade}}

====The Fall of Cybertron====
{{Main|Great Exodus|Transformers: Fall of Cybertron}}
[[File:TheCovenantOfPrimus-Grimlock.jpg|thumb|right|200px]]
[[File:WFCgalactic transports.jpg|thumb|upright=1.4|Just a little while back<ref name="greatexodustime">Assorted promotional material for the ''Fall of Cybertron'' video game dates this period to 70 million years ago. This seems ''particularly'' excessive, even for a race that normally measures its history in millions of years, and is clearly only employed to justify the presence of dinosaurs on Earth, so Shockwave can create the Dinobots by studying them. IDW's ''Fall of Cybertron'' comic addressed this by making it clear that Shockwave was looking through ''time'' as well as space, as he makes mention of the dinosaurs' extinction by meteorite, establishing that this era is ''after'' the dinosaurs died out. This is also reinforced (perhaps unintentionally) by the fact that Snarl and Sludge transform into a ''Stegosaurus'' and an ''Apatosaurus''- dinosaur species that lived almost a hundred million years before ''T. rex'', ''Pteranodon'', and ''Triceratops''. Later, solicitations for IDW's first ''Beast Hunters'' comic issue would establish that series's setting as "a few thousand years" after this era, and that comic's exact point in time would be spelled out in the final two ''Beast Hunters'' issues, placing it towards the end of the ''Prime'' cartoon in the present day era.</ref>]]

As soon as Prime reaches the surface, he orders that an exodus from Cybertron will take place immediately. Preparations are made to flee the planet, but many of the escaping [[galactic transport]]s are shot down by Trypticon Station before they can leave Cybertron's orbit. Trypticon itself comes to life, thanks to multiple sparks implanted by Shockwave, and Optimus Prime leads his forces in a battle to knock it out of orbit. The ensuing battle results in Trypticon hurtling towards Cybertron's surface. However, Trypticon is not killed, and it transforms into its robot form. After another battle with it, Optimus and his forces regroup at the site of the ''[[Ark (WFC)|Ark]]'', a deep-space interceptor and the flagship of the makeshift Autobot fleet. {{storylink|Transformers: Exodus|Exodus}} {{storylink|Transformers: War for Cybertron (360/PS3/PC)|War For Cybertron}}

With the Decepticons in control of most of Cybertron, the remaining Autobots begin fuelling the ship with scavenged Energon. Both factions develop an interest in the ancient, powerful artifact known as the [[Dark Spark]], and the Decepticons manage to locate and open the vault below Crystal City that contains it. Shockwave makes contact with the [[Insecticon (WFC)|Insecticon]]s, subterranean creatures that have been driven to the surface after Cybertron's core shut down. The Decepticon scientist manages to form an alliance with these creatures, and their sentient representatives- [[Kickback (FOC)|Kickback]], [[Hardshell]], and [[Sharpshot]]- join the Decepticons, pledging the support of their numerous feral brethren.

However, the Decepticons and Insecticons are tailed by the Autobots, and a running battle ensues, with both groups trying to return the artifact to their respective strongholds. Eventually, the Decepticons succeed in bringing the Dark Spark to Megatron at [[Kolkular]], where he places the artifact in his chest in imitation of the Matrix of Leadership. Optimus Prime arrives to confront the Decepticon leader, but is set upon by a horde of undead Autobots reanimated by the Dark Spark's power. The Autobot leader overcomes these corrupted foes and engages Megatron, and the two combatants unleash the powers of the artifacts in their chests. The power of the Matrix of Leadership wins out, violently ejecting the Dark Spark from the Decepticon leader and into space. With the artifact no longer a threat, Optimus orders the Autobots to fall back to Iacon and the Ark. {{storylink|Transformers: Rise of the Dark Spark (console)|Rise of the Dark Spark}}

While most of the Autobots ready the ''Ark'' for liftoff, the [[Lightning Strike Coalition]] warrior [[Swoop (WFC)|Swoop]] discovers a massive reserve of untainted Energon in the [[Rust Sea|Sea of Rust]]. He tries to contact [[Grimlock (WFC)|Grimlock]] and the other Autobots, but is captured by Shockwave before he can reveal the nature of his discovery. Grimlock and the rest of his squadron disobey Prime's orders and hijack an Autobot dropship to rescue him. Grimlock, [[Snarl (FOC)|Snarl]], [[Slug (FOC)|Slug]], and [[Sludge (FOC)|Sludge]] reach the outskirts of Shockwave's tower, but are overwhelmed by Shockwave's [[Insecticon (WFC)|Insecticon]]s and taken captive by Shockwave, who has plans for the quintet of warriors. Inspired by [[Dinosaur (dinosaur)|alien lifeforms]] he has viewed with ancient Space Bridge technology, he begins experimenting on them. {{storylink|Transformers Hall of Fame}} {{storylink|Transformers: Fall of Cybertron|Fall of Cybertron}} {{storylink|Transformers: Fall of Cybertron (comic)|Fall of Cybertron}}

Shockwave uses the critically injured Sludge as a test run, successfully rebuilding his alternate mode into a sauropod dinosaur, before ordering [[Kickback (FOC)|Kickback]] to dump his body in the tunnels underneath the Rust Sea. {{storylink|Beast Hunters issue 2|Beast Hunters #2}} Shockwave rebuilds the rest into powerful berserkers with saurian alternate modes and imprisons them in his tower, intending to use them as his own personal warriors. {{storylink|Transformers Hall of Fame}} {{storylink|Transformers: Fall of Cybertron|Fall of Cybertron}} {{storylink|Transformers: Fall of Cybertron (comic)|Fall of Cybertron}}

With Grimlock missing in action, Optimus leads his warriors to buy time for the Autobots to shut down Iacon and launch the Ark. Optimus discovers the existence of [[Metroplex (FOC)|Metroplex]], an enormous Autobot incorporated into Iacon's structure who has lain dormant for millions of years. Optimus and Metroplex team up to help fight the Decepticons, and despite suffering numerous injuries Metroplex manages to deal a lethal blow to Megatron, grievously injuring him. However, the attack depletes all of the Autobot's remaining supplies of energon. With Megatron out of commission, Starscream takes advantage of the situation and declares himself the new leader of the Decepticons.

Jazz and Cliffjumper go searching for Grimlock and his forces in the Sea of Rust, where they find Shockwave's tower, Sludge's body in [[stasis lock]] and the uncorrupted Energon Swoop had discovered earlier. However, on Starscream's orders, the [[Combaticon (WFC)|Combaticons]] attack the Autobot convoy, then combine into Bruticus and crash the transport, recovering half of the Energon. Starscream is unimpressed with their performance and orders their imprisonment. 

Meanwhile, Soundwave has recovered Megatron's remains and rebuilds his body, using an infusion of [[Dark Energon]] to revive him. Megatron confronts Starscream and resumes control of the Decepticons. Seeking use of Trypticon, Megatron heads for his location in Iacon and successfully scavenges many of his components. 

In Shockwave's lab, a disgraced Starscream discovers Grimlock, who he attempts to recruit to his cause. Grimlock throws Starscream into the wall and escapes. As he fights his way through Shockwave's cadre of Decepticons and Insecticons, Grimlock reunites with the surviving members of the Lightning Strike Coalition, although he believes Sludge is dead. Now operating as the "[[Dinobot (FOC)|Dinobot]]s", Grimlock confronts Shockwave and destroys his space bridge. Both are caught in the ensuing explosion.

Metroplex sacrifices his life to ensure that the ''Ark'' can launch. Optimus and many of the Autobots escape aboard the Ark. They are pursued, however, by Megatron aboard Trypticon, now a [[Trypticon (WFC)|spacecraft]] dubbed the ''Nemesis''. The two vehicles and their respective crews battle as they race for the space bridge above the planet, which explodes, scattering the two vessels across the galaxy. {{storylink|Transformers: Exodus|Exodus}} {{storylink|Transformers: Fall of Cybertron|Fall of Cybertron}}

* The [[Satellite Command Center]] at [[Polyhex]] is taken over by Decepticons. {{storylink|Transformers: Exodus|Exodus}} 
* [[Crystal City]] is razed, primarily by [[Constructicon (WFC)|Constructicons]], using their "Devastator" gestalt modes for the first time. Though the Autobots fight hard, the city is ultimately destroyed, though many of its scientific treasures escape or survive the collapse. {{storylink|Transformers: Exodus|Exodus}} 
* The Autobots win their first major victory of the Great War at [[Kalis]], primarily due to a lack of Decepticon air support. The Autobots begin to use long-range combat as a primary tactical advantage. [[Bruticus (WFC)|Bruticus Maximus]] is defeated by [[Sideswipe (WFC)|Sideswipe]], [[Jazz (WFC)|Jazz]], and [[Optimus Prime (WFC)|Optimus Prime]]. Kalis remains in Autobot hands. {{storylink|Transformers: Exodus|Exodus}} 
* The cities of [[Tarn (polity)|Tarn]] and [[Vos (polity)|Vos]] are occupied by [[Shockwave (WFC)|Shockwave]]'s forces; the Decepticon turns the two cities against one another, resulting in Tarn's destruction. Vos is destroyed not long afterwards through Shockwave's machinations, crippling Starscream's power base and allowing the mad scientist to position himself as second-in-command. {{storylink|Transformers: Exodus|Exodus}} 
* The Autobots and Decepticons battle at [[Praxus]]. The city-state is ultimately leveled by the fighting, and to this day the outcome is unclear. [[Prowl (WFC)|Prowl]] and [[Ironhide (WFC)|Ironhide]], citizens of Praxus, join the Autobot cause. {{storylink|Transformers: Exodus|Exodus}} 
* Bruticus Maximus leads a massacre at [[Nova Cronum]], killing every sentient being there. Megatron sets up a fortified command post among the ruins. {{storylink|Transformers: Exodus|Exodus}} 
* The [[Tagan Heights]] are demolished by years of fighting. It is here that the [[Wreckers]] prove crucial to the Autobot war effort, and the Autobots manage to create their own combiner, [[Defensor (WFC)|Defensor]], who fights a Devastator to a standstill. {{storylink|Transformers: Exodus|Exodus}} 
* After centuries of stasis, the [[AllSpark]] creates a final generation of Transformers, most of whom side with the Autobots. {{storylink|Transformers: Exodus|Exodus}}

[[File:OneShallRise2-bigdude.jpg|right|thumb|upright=1.4|'''CRUUUUSSSHHHH''' <br> '''ZEUUUUUUUUSSSS''']]
* Optimus orders the [[Great Exodus]] of all Cybertronians, though a small portion of the Autobots stay behind under his direct command, and the same transpires for Megatron's Decepticons. {{storylink|Transformers: Exodus|Exodus}} {{storylink|Transformers: War for Cybertron (360/PS3/PC)|War for Cybertron}} During the exodus' final days, Megatron is temporarily killed by the mighty [[Metroplex (FOC)|Metroplex]] until he is revived by Soundwave. The Autobots depart Cybertron in the ''[[Ark (WFC)|Ark]]'' while the Decepticons do so in the ''[[Trypticon (WFC)|Nemesis]]''. {{storylink|Transformers: Fall of Cybertron|Fall of Cybertron}} Some stay behind, including [[Shockwave (WFC)|Shockwave]], the [[Dinobot (FOC)|Dinobots]], and [[Ultra Magnus (WFC)|Ultra Magnus]] and his Wreckers. {{storylink|Transformers Prime: Rage of the Dinobots|Rage of the Dinobots}}
* After several adventures through the cosmos, Optimus clashes with Megatron on Earth, following which, the Decepticon leader departs into space to search for an army. While the Autobots ally themselves with the [[United States of America]], Starscream is left in command and lays low, leaving the smaller conflict stagnant until he kills [[Cliffjumper (WFC)|Cliffjumper]] three years into their stay on Earth. Three human children, [[Jack Darby]], [[Miko Nakadai]], and [[Raf Esquivel]] are caught up in the conflict and become members of Optimus' [[Team Prime|unit]]. Megatron soon returns and brings Dark Energon to Earth, officially renewing the war. {{storylink|Darkness Rising}}
* The Autobots and Decepticons ally to defeat [[Unicron]], who is revealed to be [[Earth's core]]. {{storylink|One Shall Stand}}
* After a lengthy arms race over [[Project Iacon|relics scattered on Earth]], both factions battle over the right to revive Cybertron through the [[Omega Lock]], but when forced into a corner, Optimus destroys it, dooming Cybertron to remain lifeless. The Autobots are dealt a crushing defeat by Megatron in retaliation, {{storylink|Darkest Hour (episode)|Darkest Hour}} but eventually successfully regain lost ground when Ultra Magnus arrives on Earth. {{storylink|Rebellion (Prime)|Rebellion}}
[[File:Deadlock-Megatron-Decepticons-extinguished.jpg|upright=1.4|left|thumb|Well, at least I don't have to pay the power bill for this stupid insignia anymore!]]
* On the verge of creating a new army of cloned [[Predacon (Prime)|Predacons]], the Decepticons lose more than half of their military strength thanks to a mishap involving a [[Terrorcon (Prime)|Terrorcon]] infestation, severely weakening their war effort. {{storylink|Thirst}} This coupled with [[Predaking (Prime)|Predaking]] revealing his sentience causes Megatron to terminate the cloning scheme, and he resolves to repair the Omega Lock. {{storylink|Evolution}} {{storylink|Minus One}}
* When the Omega Lock is completed, the Autobots attack the ''Nemesis'', killing Megatron and reviving Cybertron, effectively ending the Great War with an Autobot victory. {{storylink|Deadlock (episode)|Deadlock}} After reclaiming the AllSpark, Optimus returns to Cybertron to find Unicron attacking the planet, and seals the Chaos Bringer away. Optimus sacrifices himself to restore the AllSpark to the Core of the planet, while a revived Megatron dissolves the Decepticon movement. {{storylink|Predacons Rising (Prime)|Predacons Rising}}
