Unicron

He's been ignoring Galactus's C&D letters.

Unicronis the eternal arch-enemy of his twin brotherPrimus.Also known as theLord of Chaos,the Chaos Bringer, and the Planet Eater, he is dedicated to consuming themultiverse.His massive form is powered by the consumption of planets, moons, stars, and even the very fabric of existence. Unicron will not be sated until his ultimate goal is attained: to bring an end to the annoying creation boasting independence around him, and find peace by becoming the living center of aswirling, infinite torrent of nothingnessat the end of all things.

To undertake this seemingly overwhelming task, Unicron is able to travel across realities at will, a meandering plague upon existence itself.^[1][2]Integrated into his systems are incomprehensible quantum computers which calculate probabilities forward and backwards in time, in perpetuity, giving his processors an ever changing, evolving map of the multiverse.^[3]With these abilities at his disposal, Unicron has thus far devoured approximately 22.56% of known universes. Seen at a detached distance from the multiverse, this collective "Unicron Phenomenon"acts with the characteristics of a virus or plague seeping through reality, succeeding where it can, retreating when it cannot.^[4]Various permutations of Unicron can spawn into existence outside the trappings of the larger entity, hailing from a more mundane origin but possessing the same consumptive traits.^[5]For much of multiversal history, thesingularityUnicron threatened all of existence, but now,that is no longer the case,and versions of Unicron are now restricted to their own dimensions.

The only thing that he fears is Primus's essence, contained inside theMatrix of Leadership.To a being of chaos and uncreation, this font of life is a poison.

Frequently, Unicron will make deals withlesserbeings,promising them vast new powers in exchange for their servitude. These minions aresometimesstripped entirely of free will, butmanyothersfollow willingly. Service to Unicron, however, is a double-edged sword, for it causes insanity and loss of self. And in the end, Unicron's plans ultimately call for their consumption as well.

Conceptual history

Unicron debuted as the central antagonist of 1986'sThe Transformers: The Movie,which established him as a monstrously powerful being seemingly only vulnerable to the supernatural energies contained within the AutobotMatrix of Leadership.The Moviepresented Unicron as more of an abstract obstacle than a full-fledged character: it didn't explain what Unicron was, nor where he came from, or any specific reasoning for why Unicron specifically targetedCybertron.Subsequent episodes ofThe Transformerscartoon,set in the samecontinuityasThe Movie,were the first works ofTransformersmedia to fill in these details and craft the first of Unicron's many origin stories: as related in the third season episode "Call of the Primitives",the cartoon's Unicron was created by an alien scientist known asPrimacron,but Unicron rebelled against his creator and set out into space alone.

However, theMarvelTransformerscomichad incorporated its own version of Unicron intoits own universe,entirely separate from the cartoon's goings-on. Starting in1988,authorSimon Furmanestablished an entirely different backstory for the character, tweaking details as necessary as the storyline evolved. As first recounted in "The Legacy of Unicron!",the comic's Unicron was the one of theDark Gods—in the early days of the universe, he had menacedPrimuslord of theLight Gods,and their battle ended with Primus reshaping his body into the metallic planetoid that would one day become Cybertron. Primus entrustedthe first Transformerwith a fragment of his own essence, which became the Matrix. With each retelling of the story, the roles of the Dark and Light gods diminished; finally, inissue #74,it was revealed that Unicron predated the universe itself, having devouredthe previous universein ancient times, and that the sentient core of the universe had created Primus to defeat him—as a result, his attacks on Cybertron became merely the latest attempt to snuff out his age-old enemy.

Unicron didn't appear in theBeast WarsorBeast Machinescartoons, although the alienVokadopted his countenance in the episode "Other Voices, Part 1",and dialogue suggests that events similar to those ofThe Movieoccurred at some point in Cybertron's history. However, Unicrondidappear in theBeast Machines-adjacentUniversefranchise, which featured him kidnapping Cybertronians from across theTransformersmultiverse.

That same year, Unicron starred as the final boss of theTransformers: Armadafranchise. While theArmadacartoonepisode "Origin"put a cerebral spin on Unicron's villainy by revealing that he'd deliberately created theMini-Consas a way to agitate the ongoing Cybertronian civil war, theDreamwave comictook inspiration fromUniversein its depiction of Unicron as an interdimensional threat, systematically devouring his way across realities before moving on to his next target. Around this time, a set ofArmadatrading cards released by Fleer nailed down the first "modern" interpretation of the Primus/Unicron mythos: inthistelling, the two were brothers who'd been created by an extradimensional entity named the "Allspark"at the dawn of time to explore the universe. This was subsequently expanded on and combined with aspects of the various Marvel Comics stories inTransformers: The Ultimate Guide,written bySimon Furman,who had written all three prior tellings in the first place. Here, the entity Fleer had called the "Allspark" was redubbed "The One",and the modern iteration of the myth detailed above was firmly established, and went on to form the backbone of most subsequent fiction. Unicron played a significant role inArmada'sdirect sequel,Energon;that franchise ended with Unicron's remains collapsing into a massive black hole, and this "Unicron Singularity"became the primary threat inCybertron.As a result of his prominence in all three franchises, these are often referred to as the "Unicron Trilogy".In the pages ofThe Ultimate Guide,Furman also established that the originalThirteenTransformers had been created specifically to battle Unicron at the dawn of time, and this detail would become a staple of the Primus/Unicron origin myth.

In 2005, Hasbro copywriterForest Leebuilt off Unicron's "Worlds Collide"backstory; in the pages of theofficial Collectors' Clubmagazine, he laid down the idea that Unicron was a "multiversal singularity"—across all the variousTransformersstories, there was onlyoneUnicron capable of crossing dimensions at will. Although subsequentFun Publicationsmedia embraced the notion, the idea never really caught on outside this specific niche: theBlack Horizoncrossover epic presented Unicron as a rogue alien who'd been banished from his world, and the "Aligned"continuity established that Unicron andEarthwere one and the same; notably, none of this lore ever attempted to reconcile Unicron's origins in the original Sunbow cartoon with the Marvel-inspired lore that had superseded it. In 2015, the "Ask Vector Prime"column massaged the notion by revealing that there were both" singularity "and" non-singularity "iterations of Unicron, and specifically highlighted the Unicron ofThe Movieas one of these non-singularity iterations.

As inconsistencies piled up, however, Fun Publications chose to do away with the idea entirely—in 2015, the "Another Light"story arc introduced theShroud,an in-fiction event that retroactively nullified all multiversal singularities into an infinite series of alternate selves. From this point onwards, creators have the freedom to depict Unicron however they wish—be it aplanet-eating god of destruction,anultraterrestrial threat,or arogue weapon created by an alien scentist—all these depictions and more can now freely coexist.

The nearly-dead body ofa ravaged universe'sOptimus Primewas sent ahead by Unicron to hisnext target universe,as a "calling card". Additionally, Unicron sent a group of heralds—incarnations ofBludgeon,Dirge,Galvatron,Scourge,andThunderwing—to this second universe to find theMini-Con Matrixand kill that universe's Optimus Prime and Megatron. The heralds did not realize that their target Optimus Prime had been accidentally transported to the initial, dying Cybertron.Worlds Collide, Part 1 of 4

Optimus Prime found one lone survivor,Spinister,and begged him to tell him what was going on. Spinister told him that the "heart of darkness, the root of all evil" had ravaged their world.Worlds Collide, Part 2 of 4Worlds Collide, Part 3 of 4When Unicron loomed over them, Spinister surrendered himself to his fate. Spinister soon returned as an avatar for Unicron, who found this Optimus Prime's presence to be an "anomaly". SoonJetfiremanaged to trace Optimus Prime to this dying universe and travel there to rescue him. Using the power of the Mini-Con Matrix, Prime and Jetfire were able to combine into Jet Optimus and fire a powerful shot into the heart of Unicron. Though they were too late to save this Cybertron, they could return home and prepare for Unicron's coming there.Worlds Collide, Part 4 of 4

Optimus Prime called for an alliance with the Decepticons and the Mini-Cons, hoping to unite their forces against the coming Dark god. After warping to Cybertron's surface, Unicron himself arrived, and announced that they would all soon be consumed. During the following battle, Unicron was curious about the TransformersAirazor,Cheetor,Rhinox,andTerrorsaur,and abducted them for future purposes. Unicron was ultimately defeated by the Mini-Con Matrix, boosted from the additional power of two universes' Mini-Cons. This universe'sMegatron,having made a bid for Unicron's power, was standing on the surface of the planet-eater when he was destroyed, and his body was also lost, his spark trapped within Unicron's remains.The End

Optimus Prime, who received a telepathic message from the disembodied Megatron, turned to theAutobot High Councilfor permission to dedicate an army towards Unicron's return and his intent to consume alleged huge amounts ofenergonon Earth, but the Council dismissed these concerns as paranoia. While they did not grant Prime his army, they did permit him to travel to Earth alone. Before Prime could get out of the building, Unicron's Horsemen struck. Prime and the Council realized this was an act of war perpetrated by Unicron, and so Prime's original pleas were finally heard.What Lies Beneath

Megatron countered with images of a massive-scale Terrorcon attack on Earth. Alpha Quintesson had used Unicron's power to reconfigureTidal Waveinto Mirage, andMoscow,Toronto,andLos Angeleswere under heavy siege from his Terrorcon army. Still, Optimus Prime resisted helping Megatron, even with the promise of teaming up to destroy the remnants of Unicron, as he feared releasing Megatron in his new body would be unleashing an equal evil.Multiplicity

Finally, after images of carnage on Earth overwhelmed him, Optimus Prime caved to Megatron's demands, and Prime began traveling through Unicron under Megatron's direction. After falling in some goo, Prime located the sensor array that was keeping Megatron's consciousness from entering his new body.

Cartoon continuity

Unicron was evidently very active in this universe at various points in time, although the precise chronological order of his activities is unclear.

At some undetermined point in the past of this universe, Unicron was approached by the survivors ofPlanet X,a world that had been destroyed in a war with the inhabitants of the Giant Planet,Gigantion.In return for the chance to gain revenge on Gigantion, the survivors swore loyalty to Unicron, and "Planet X" became something of a code-phrase that identified those in the service of the planet-eater.

That's no moon!

Unicron's first attack on Cybertron was over a million years in the making, begun when he opted to disguise his dormant body as Cybertron's moon. From this secret vantage point, he implanted his own cells within the planet, where they germinated and grew into the small race of robots known as theMini-Cons.Unicron hoped to use the Mini-Cons to increase the ferocity of the Autobot/Decepticon war, and feed off of the energies released in the conflict. The Cybertronians would then be subjugated through the Mini-Cons' influence. Though his plan succeeded in one timeline, the interference of three time-displaced children changed this.Rad White,Carlos Lopez,andAlexis Thi Dangplanted the seed of sentience and free will within the Mini-Cons, who ultimately rebelled against their creator and fled Cybertron, crash-landing on the planet Earth. This forestalled Unicron's emergence by eons.OriginDrift

Don't mind me, just chillin'.

Again, it was thanks to the Autobots' human allies—the same children who had been sent back in time and given the Mini-Cons free will in the first place—that the Mini-Cons struggled free of Unicron's control, including the three Mini-Con weapons, who broke free and left Unicron's body deactivated.OriginBelieving the threat over,Galvatronthen challenged Optimus Prime to their final battle, only for the hatred and ferocity of their fight to awaken Unicron once more.

In truth, however, Unicron had survived, and for the next ten years, continued to consume planets in other regions of space. One such planet was the world known asPlanet Q,whose inhabitants fought back by detonating the planet's core in Unicron's face. Badly damaged by the explosion, Unicron fell into a state of dormancy, but the life essence of the planet's ruler—the being who would come to be known asAlpha Q—continued to exist within him, and began a not-entirely-sane plan to use Unicron's powers to recreate everything the Chaos-Bringer had ever destroyed.Alpha Q: IdentityRecreating the armies of Planet Q as "Terrorcons", Alpha Q had them attack Autobot facilities on Earth and throughout theSolar Systemto gather theenergonthat would be necessary for his plan to work.Cybertron City

None of the Transformers were aware, however, that Unicron lived on in two forms: his miniscule Spark, floating in space, and his consciousness, which lay buried in Megatron's mind.

At some point in time, a virtual copy of Unicron appeared in an Autobot "virtual training program" as a special opponent for Hot Shot and Rodimus to battle after defeating all other contenders.

Enraged, Galvatron prepared to destroy Unicron's Spark, but it merged with him, enlarging him again, leading to another battle with Optimus Supreme, this time bolstered by the combined energy of all his troops' Sparks. Meanwhile, Primus merged with the Super Energon, creating a foundling sun which arrived at the site of the battle. Taking control of his body for a brief moment, Galvatron made the decision to plunge himself into the infant sun to rid himself of Unicron's possession.

In the distant past, the planetEarthformed around the inert body of Unicron. OnCybertron,Unicron was known as the planet's ancient enemy. Abookthat would eventually come to be held in the Trinity Library spoke of Unicron beingthe core of Earth.

Somehow the Cybertronian sorceressQuintessahad discovered Unicron's resting point and hit on a plan to restore Cybertron by draining the life from Unicron to revive the planet, sending bothMegatronand a brainwashedOptimus Primeto Earth to reclaimthe deviceshe needed to complete her plan.

I see a bad moon rising
I see trouble on the way

In preparation, Quintessa moved Cybertron into Earth's solar system, its presence causing Unicron's six horns to sprout on the Earth as he reacted to the presence of his old enemy. Growing at a rate of three meters a day, the horns were a sign of a great scientific curiosity and mass panic across the globe.Sir Edmund BurtonandCogmanrecognized the horns for what they were and took them as a sign of the apocalypse.

At Stonehenge, Quintessa andMegatronbegan the ritual and sent Unicron's life force to Cybertron before the Autobots and the TRF halted their efforts. Enough of Unicron's life force had been sent to Cybertron however that it had healed most of its damage to the point that the Autobots felt they were able to return to their homeworld.

In the aftermath, several human scientists were examining one of Unicron's horns only to be approached by Quintessa in a human guise. She warned them against touching the horn, lest they incur Unicron's wrath, but offered them a way to kill the Chaos Bringer.The Last Knight

This is your final warning: break the treaty again and you will be destroyed.

Legends that predated Cybertronian civilization described Unicron as a dark god who consumed planets, but few knew of the legends, and fewer still believed them. TheMaximalslearned that Unicron was real only when the Chaos Bringer arrived on their doorstep to consume their planet. Unicron deployed his Terrorcon and Predacon forces led by his chiefHeraldScourge,who he had long ago enslaved. Unicron tasked them with finding theTranswarp Key,a Maximal device that would enable him to continue his rampage across time and space at will, before he consumed the Maximal planet. Unicron was livid with Scourge for losing the key as the Maximals led byOptimus Primalfled, and commanded Scourge to find the key. Though Unicron was still able to feast on the Maximal planet, he was left in the current galaxy, forced to rely on his own power to move about space, but this soon left him starving and desperate to find another planet to feast on.

Scourge later found half of the Transwarp Key on Earth in 1994, but when he presented his prize to his master, Unicron scolded and tortured his minion as it was only half of the key. Scourge eventually retrieved the other half in Peru and began opening a portal in time and space for Unicron to come through. Unicron relished his apparent victory and made ready to devour Earth, but Primal andOptimus Prime'sAutobots defeated Scourge and his other forces. When Prime made to destroy the portal, Unicron hastily offered Prime whatever he wanted in exchange for not proceeding, but the Autobot leader had none of it and destroyed the portal. Though Unicron had been stranded once again in his current location and time, the Autobots and Maximals acknowledged he had likely survived the collapse of the portal, but stood resolute that they would defeat him should he ever return to Earth.

"The psoriasis is barely slowing him down!"

In an alternate timeline where Megatron won the battle of Mission City,Stockadeand his Decepticon chums attempted to rebirth Cybertron by sending out a summons that would attract any entity related to the lostAllSpark,and then drawing that entity into Cybertron once it arrived.

As that entity announced itself to be"Unicron the Anti-Life!",they felt like a right bunch of plonkers.Return to Cybertron: Part 2

Unicron moved swiftly, transforming Cybertron into a scarier looking physical form and causing the planet's surface to becoming hostile to the Transformers on it. Stockade's attempts at communication were met with contempt and a strange attack. The new Unicron then warped into the Sol system, shot down an Autobot shuttle, and went "OM NOM NOM" at the sight of Earth.Return to Cybertron: Part 3

The downed Autobots regrouped with Stockade's Decepticons and worked to take away theNucleonthat was powering Unicron's physical form. They succeeded in this by causing it to blow up and catch fire, which caused Unicron to draw on more Nucleon to recover, which fueled the fire and so on until the source ran out. Unicron disappeared, though whether he was dead or just gone is ambiguous.Return to Cybertron: Part 4

Either way, the changes Unicron had made to Cybertron remained. The teleportation equipment he'd created was used by the Autobots to finally end the war.Revolution Part Three

Vector Prime was unsure if the number of universes destroyed by Unicron was a quantifiable number as once Unicron consumed a universe, little remained to prove that it ever existed. However, some destroyed universes, such asPrimax 703.09 Gamma,lived on the memory of interdimensional travelers who had visited the universe prior to its destruction.Ask Vector Prime, 26/06/2015

Unicron takes a shot in the mouth.

After the Autobots defeated the Decepticons onEarthand had secured the majority of the Mini-Cons there, Unicron made his appearance above Cybertron, intent on destroying the planet. Optimus Prime's team of Autobots and the Mini-Cons returned home via a warp gate to see the Chaos Bringer unleash a wave of destruction upon the great cities of their planet. The Mini-Cons joined to form theMatrix Cannon,theVanguard Boosterand theNemesis Shieldfor the Autobots to use against Unicron. The Autobots flew into Unicron's maw and blasted their way into his energy core, damaging it enough to send Unicron spiralling out of control and destroying him.Transformers

Transformers Energon: Battle for Megatron

In his attempts to stop Scorponok and the other Terrorcons from retrieving Megatron, held deep within Unicron himself, the Chaos Bringer dispatched many units acting as his automated defenses. Among these were Pods, weak individually but strong in numbers; Tentacle Pods, more advanced versions of the previous units possessing ranged attacks; slow moving but strong Tendril units; heavily armored Spiderbot units; and immobile but powerful Shocktowers. A final unit, The Cortex, held Megatron captive. Once The Cortex was destroyed, Megatron was released and Unicron was defeated.Transformers Energon: Battle for Megatron
