Unicron

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

Unicron is the eternal arch-enemy of his twin brother Primus. Also known as the Lord of Chaos, the Chaos Bringer, and the Planet Eater, he is dedicated to consuming the multiverse. 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 a swirling, infinite torrent of nothingness at 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, the singularity Unicron 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 the Matrix of Leadership. To a being of chaos and uncreation, this font of life is a poison.

Frequently, Unicron will make deals with lesser beings, promising them vast new powers in exchange for their servitude. These minions are sometimes stripped entirely of free will, but many others follow 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's The Transformers: The Movie, which established him as a monstrously powerful being seemingly only vulnerable to the supernatural energies contained within the Autobot Matrix of Leadership. The Movie presented 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 targeted Cybertron. Subsequent episodes of The Transformers cartoon, set in the same continuity as The Movie, were the first works of Transformers media 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 as Primacron, but Unicron rebelled against his creator and set out into space alone.

However, the Marvel Transformers comic had incorporated its own version of Unicron into its own universe, entirely separate from the cartoon's goings-on. Starting in 1988, author Simon Furman established 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 the Dark Gods—in the early days of the universe, he had menaced Primus lord of the Light Gods, and their battle ended with Primus reshaping his body into the metallic planetoid that would one day become Cybertron. Primus entrusted the first Transformer with 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, in issue #74, it was revealed that Unicron predated the universe itself, having devoured the previous universe in 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 the Beast Wars or Beast Machines cartoons, although the alien Vok adopted his countenance in the episode "Other Voices, Part 1", and dialogue suggests that events similar to those of The Movie occurred at some point in Cybertron's history. However, Unicron did appear in the Beast Machines-adjacent Universe franchise, which featured him kidnapping Cybertronians from across the Transformers multiverse.

That same year, Unicron starred as the final boss of the Transformers: Armada franchise. While the Armada cartoon episode "Origin" put a cerebral spin on Unicron's villainy by revealing that he'd deliberately created the Mini-Cons as a way to agitate the ongoing Cybertronian civil war, the Dreamwave comic took inspiration from Universe in 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 of Armada trading cards released by Fleer nailed down the first "modern" interpretation of the Primus/Unicron mythos: in this telling, 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 in Transformers: The Ultimate Guide, written by Simon 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 in Armada's direct sequel, Energon; that franchise ended with Unicron's remains collapsing into a massive black hole, and this "Unicron Singularity" became the primary threat in Cybertron. As a result of his prominence in all three franchises, these are often referred to as the "Unicron Trilogy". In the pages of The Ultimate Guide, Furman also established that the original Thirteen Transformers 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 copywriter Forest Lee built off Unicron's "Worlds Collide" backstory; in the pages of the official Collectors' Club magazine, he laid down the idea that Unicron was a "multiversal singularity"—across all the various Transformers stories, there was only one Unicron capable of crossing dimensions at will. Although subsequent Fun Publications media embraced the notion, the idea never really caught on outside this specific niche: the Black Horizon crossover epic presented Unicron as a rogue alien who'd been banished from his world, and the "Aligned" continuity established that Unicron and Earth were 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 of The Movie as 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 the Shroud, 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 a planet-eating god of destruction, an ultraterrestrial threat, or a rogue weapon created by an alien scentist—all these depictions and more can now freely coexist.

In the Primax universal cluster, Unicron had many incarnations, all often attacking Cybertron at some point and being destroyed by the Transformers that lived there. He also would repeatedly serve as a Faustian devil; making deals with lesser lifeforms in return for servitude. Among his most famous of those was Megatron, who would often be reformatted into the powerful Decepticon known as Galvatron.

Dreamwave Armada comic

The southern hemisphere is known as the "footsmell" region.

The nearly-dead body of a ravaged universe's Optimus Prime was sent ahead by Unicron to his next target universe, as a "calling card". Additionally, Unicron sent a group of heralds—incarnations of Bludgeon, Dirge, Galvatron, Scourge, and Thunderwing—to this second universe to find the Mini-Con Matrix and 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 4 Worlds Collide, Part 3 of 4 When 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". Soon Jetfire managed 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 Transformers Airazor, Cheetor, Rhinox, and Terrorsaur, 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's Megatron, 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

Energon comic

You never see him transform to robot mode.

Ten years later, his broken body was still left floating in space after his defeat. Despite his damaged form, his core presented huge potentials for power, and so Alpha Quintesson gathered together a group of Decepticon dissidents under the leadership of Scorponok and transformed them into "Terrorcons". He promised these Terrorcons this power in exchange for their services. This Evil Reborn Meanwhile, Megatron's consciousness was trapped within this core, and over time was able to use Unicron's systems to create for himself a new body, though he was unable to transfer his spark into it. What Lies Beneath, Part Three

Alpha Quintesson was secretly working for Unicron himself, and he sent the corrupted forms of Airazor, Cheetor, Rhinox, and Terrorsaur, his "Four Horsemen", to Cybertron to distract the Autobots from Unicron's revival. This Evil Reborn

Optimus Prime, who received a telepathic message from the disembodied Megatron, turned to the Autobot High Council for permission to dedicate an army towards Unicron's return and his intent to consume alleged huge amounts of energon on 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

Unicron has a big negative universe Cyclonus collection.

After they were defeated by Optimus Prime on Earth, Scorponok and his Terrorcons were forcibly brought back to Unicron for disciplinary action by Alpha Quintesson. What Lies Beneath, Part Four Afterwards, Optimus Prime stepped through a portal back to Cybertron to assemble a team of reinforcements... but instead found himself brought to within Unicron, summoned by Megatron's consciousness. Omni-Potent Optimus Prime argued with Megatron, denying that he would ever help his thought-dead foe inhabit his new body. Megatron countered with images of a massive-scale Terrorcon attack on Earth. Alpha Quintesson had used Unicron's power to reconfigure Tidal Wave into Mirage, and Moscow, Toronto, and Los Angeles were 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. It worked, and Megatron was freed... though Optimus Prime was subsequently located by Unicron's internal defenses. Multiplicity, Pt. 2 But through sheer force of will, Optimus broke through Unicron's immune system, and managed to allow Megatron access to his new body. Multiplicity, Pt. 3 Optimus was last seen having defeated the remnants of Unicron's antibodies, with a bandolier and his hand-held cannon. He boasted to Unicron that he was coming for him. No Exit

Previously, Unicron had destroyed Quintessa, and Alpha Quintesson was the sole survivor. With the Initiator, Alpha attempted to escape Unicron, only for his ship to be pulled to the planet eater. Doomsday Redux! The energon used for Unicron's reactivation came not from Earth, but from Nervissa, a fact Optimus Prime discovered after connecting to Unicron's consciousness. Armageddon Part 1 Alpha Quintesson sought to destroy Unicron and had a seismic-shock warhead teleported to Unicron. Armageddon Part 2 Within Unicron, Optimus gambled that he would need to make contact with Cybertron if he had any chance of escaping the malevolent planet. He ascended to Unicron's surface, only to come upon the warhead, right after it had been teleported in. Armageddon Part 3 In the later chaos of an alternate-universe Quintesson invasion of Cybertron, Unicron awoke and began to strike out against the Transformers. HIs first target was Megatron, who had teleported back to within his body to confront Alpha Trion. Armageddon Part 4 Realizing that their planet was open to Unicron's attack, the Quintessons attacked Unicron, to no avail. The Quintessons were destroyed, and the Transformers managed to delay Unicron enough for the warhead to explode, destroying the planet. The shockwaves from Unicron's destruction created a black hole from the portal to the alternate-universe Quintessa. Armageddon Part 5

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 of Planet 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.

Cybertronian legend referred to an attack by Unicron on the planet that was ultimately thwarted by the mighty Autobot warrior, Omega Supreme. Omega Supreme

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 the Mini-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, and Alexis Thi Dang planted 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. Origin Drift

Don't mind me, just chillin'.

When the Mini-Cons were reawakened a million years later in 2010, they were detected by the Autobots and Decepticons, who followed their signal to Earth. First Encounter Unicron also picked up the signal, and dispatched his minion Sideways to carry on his work. Gale Rad, Alexis, and Carlos encountered a digital manifestation of Unicron when Sideways transported them to a digital world, in a bid to steal the Street Action Mini-Con Team from them. Unicron's avatar gave chase to the children as they fled back into the physical realm, but was unable to catch them in time. Chase Sideways then continued to escalate the conflict by manipulating control of the three Mini-Con weapons, the Star Saber, the Skyboom shield and the Requiem Blaster, but eventually arranged for all three to be returned to Cybertron, where he stole them and used them to reawaken Unicron. Portent While still awakening, Unicron sent an energy bolt down at Starscream, who had fired a powerful blast at the Dark God to convince Galvatron of his threat. Starscream was disintegrated before his shot could even reach Unicron. Cramp

The Power Cosmic gives you wrinkles.

Shedding his moon disguise and transforming to robot mode, Unicron turned on Cybertron, only to be met with resistance in the form of the united armada of Autobots and Decepticons Alliance, and his own Mini-Cons, who had linked together and formed a giant duplicate of his body. Union Now at full power, however, it was child's play for Unicron to exert control over his creations, and bring the Mini-Cons under his thumb once more. 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. Origin Believing the threat over, Galvatron then challenged Optimus Prime to their final battle, only for the hatred and ferocity of their fight to awaken Unicron once more. To end the circle of hate that gave Unicron life, Galvatron allowed himself to be consumed by the monster, and in a brilliant flash of light, Unicron apparently ceased to exist. Mortal Combat

While traversing the Linkage dimension, Redline noticed an ominous presence watching him. Linkage Part 7 Redline recognized it as "The Terrible One" and relayed that info to Servo, who then relayed it to Rollbar. Having also seen The Terrible One while in the Linkage, Falcia chose to stay with Redline and work with him on the Master Key. Meanwhile, Sideways, a minion of Unicron, gave the Speed Chaser Team, also minions of Unicron, the Doomstone, an artifact intended to permanently enslave the Mini-Cons to Unicron's will. Linkage Part 8

The Doomstone was then installed in Ravenus, who used its evil energies to destroy the souls of the Mini-Cons and revert them into mindless death-machines. Linkage Part 10 Ravenus and the Doomstone intended to destroy the Earth. Linkage Part 11 Redline and Kingbolt were able to contain Ravenus and extract the Doomstone. Redline then sealed it away in his extra-dimensional storage space for safekeeping. Linkage Part 12

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 as Planet 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 as Alpha 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: Identity Recreating the armies of Planet Q as "Terrorcons", Alpha Q had them attack Autobot facilities on Earth and throughout the Solar System to gather the energon that would be necessary for his plan to work. Cybertron City

Unicron sported awesome colors during Energon.

Unbeknownst to Alpha Q, Megatron's corpse and spark remained within Unicron, and he slowly siphoned off some of the gathered Energon, allowing him to be reborn in his own new body. To escape Megatron's fury, Alpha Q jettisoned Unicron's head and escaped in it, Megatron Resurrected while Megatron took over Unicron's body, and continued to gather Energon in order to rebuild Unicron to use as his ultimate weapon. Megatron Raid Both parts of Unicron's inert form were used by Megatron and Alpha Q as their bases from then on. Though Unicron briefly lashed out towards those housed within him when he became starved with energon, he otherwise remained incapable of attacking them. Survival Instincts

As the climax of Megatron's plans neared, a joint attack by Alpha Q, the Autobots and their human allies saw all of Earth's Energon channeled into Unicron's head, which Alpha Q then rammed into Unicron's body. Unicron Unleashed The positively-charged Energon of Earth reacted with the negatively-charged Energon running through Unicron, tearing open a fissure in reality leading to a new area of space where planets Unicron consumed were recreated, and sustained through the Energon radiated from Unicron's head, which had now become a glowing red sun. Open Fire! Ripped Up Space Farewell Inferno

Unicron should stop eating so many Blizzards.

Unicron's body, damaged once more, lay in the dark reaches near the fissure, and the Decepticons began to raid Alpha Q's new planets for the Energon necessary to revive Unicron again. This time, they succeeded, Omega Supreme and Megatron directed Unicron's body to retrieve his head, extinguishing the Energon Sun and killing Alpha Q in the process. A Heroic Battle But the power of Unicron proved too much for Megatron to control, as Unicron began to take over Megatron's body. The Power of Unicron The Autobots made a valiant but futile attempt to stop him, and Unicron swatted them like gnats. Just as things seemed hopeless, a surge of power from Primus allowed Optimus Supreme to grow to Unicron's size and powered up the other Autobots. Optimus Supreme After a long and hard battle, Optimus destroyed Unicron's body. Unicron Perishes

"Geodude geeeeoooo geodude."

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. With quiet, subconscious nudging, Unicron led Megatron to a massive reservoir of "Super Energon" beneath Cybertron's surface, Ambition which transformed him into Galvatron upon his first exposure. Wishes Galvatron used his newfound power to take command of Cybertron, exiling the Autobots off-world by unleashing a toxic energon gas into the atmosphere. Unicron next pushed Galvatron to use the planet's systems to propel Cybertron towards Alpha Q's planets. Galvatron! The Omega Train

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. Despite this copy being scaled-down to be about the same size as his opponents, he proved to be a formidable foe. The Autobots nonetheless defeated him, winning the video game training exercise.

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. The super energon mass, having now received Unicron's spark, ignited into a powerful red sun which gave new life to Alpha Q's worlds. The Sun

The cause of—and solution to—all of our continuity problems.

Primus's plan to trap Unicron in the heart of a new sun failed when the star collapsed into a massive black hole (sometimes known as the "Unicron Singularity") that threatened the entire multiverse. The collapse of the sun also allowed Megatron to escape, but not before integrating what remained of Unicron's body into himself, increasing his power to nightmarish new heights. Fallen

Revelation Fury The Decepticon leader's newest plan also held hints of the dark god's old agenda, as he intended to use the Keys to accelerate the black hole's growth and destroy the entire universe (albeit with the intent to remake it in his image afterwards).

Unfortunately for Unicron and Megatron (who again upgraded into Galvatron), the black hole would be sealed away by Primus himself after the Autobots restored his full power.

In the distant past, the planet Earth formed around the inert body of Unicron. On Cybertron, Unicron was known as the planet's ancient enemy. A book that would eventually come to be held in the Trinity Library spoke of Unicron being the core of Earth.

Somehow the Cybertronian sorceress Quintessa had discovered Unicron's resting point and hit on a plan to restore Cybertron by draining the life from Unicron to revive the planet, sending both Megatron and a brainwashed Optimus Prime to Earth to reclaim the device she 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 Burton and Cogman recognized the horns for what they were and took them as a sign of the apocalypse.

At Stonehenge, Quintessa and Megatron began 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

Unicron might as well eat this planet -- it's so close to its sun it's gotta be uninhabitable!

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. The Maximals learned 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 chief Herald Scourge, who he had long ago enslaved. Unicron tasked them with finding the Transwarp 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 by Optimus Primal fled, 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 and Optimus Prime's Autobots 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, Stockade and his Decepticon chums attempted to rebirth Cybertron by sending out a summons that would attract any entity related to the lost AllSpark, 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 the Nucleon that 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

This is the good Unicron. Hard to believe, right?

Ask Vector Prime

Vector Prime noted that the non-Singularity Unicron of Primax 984.17 Alpha or Viron 704.08 Gamma would not be able to defeat Darth Vader's Death Star mech of Lukas 577.25 Beta in battle. Ask Vector Prime, The Complete AllSpark Almanac

In many universal streams, the local iteration of Primacron built his universe's version of Unicron, one that was typically not part of the singularity. Ask Vector Prime, 22/05/2015 Two such instances included Primax 984.17 Alpha and Malgus 1207.26 Alpha. Ask Vector Prime, 10/06/2015

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 as Primax 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

While on an inter-dimensional mission to Primax 207.0 Epsilon's Earth in Primax -408.24 Epsilon, the GoBot Small Foot had a vision in which Unicron devoured her allies, plunging them into an eternal abyss. High Noon

Transformers (PS2)

Voice actor: Matthew Yang King (English), Arturo López (Castilian Spanish), Pietro Ubaldi (Italian)

Unicron takes a shot in the mouth.

After the Autobots defeated the Decepticons on Earth and 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 the Matrix Cannon, the Vanguard Booster and the Nemesis Shield for 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

Notes

• The Unicron Trilogy, the series of Transformers franchises that includes Armada, Energon, and Cybertron, was so named by Hasbro designer Aaron Archer because of Unicron's importance in each story.
• Roberto Orci was interested in having Unicron in an early version of Dark of the Moon.^[6] Thought he was absent in the finished film, Unicron would eventually make his "movie series" debut in The Last Knight. It wasn't until a mere six years after The Last Knight that Unicron would finally physically make his debut proper in Rise of the Beasts.
• Unicron has the ability to create tainted worlds, but none have yet been discovered.
• Unicron developed something of a taste for BotBots during the development of his HasLab toy.^[7]
