I usually don't look nearly as cool as this.

A Unicron or lots of Unicrons did lots of stuff in the Primax universal cluster. It's not all very clear.

So anyway, here I'm built by a monkey. Sorry.

Unicron was constructed by the ancient genius known as Primacron at the dawn of the universe. Primacron had hoped that Unicron would scour the galaxy clean of life, leaving a blank slate for him to experiment upon, but naturally, Unicron had no desire to be the servant of another, and turned on Primacron, badly wounding him and his assistant, and setting out into the depths of space. Call of the Primitives

I see you down there!

In the year 2005, Unicron made his most famous attack upon Cybertron. While heading towards the planet, he consumed the small world of Lithone, making it perfectly clear how great a threat he was to the entire universe. As he continued on his way, Unicron's powers allowed him to become aware of the death of Optimus Prime, who handed the Matrix of Leadership to Ultra Magnus just before dying, which angered him tremendously. He then came upon the bodies of several wounded and dying Decepticons, who had been dumped into space following a recent battle on Earth. He extended a proposition to the Decepticons' leader, Megatron, offering to rebuild his body and those of his troops in exchange for their destruction of the Autobot Matrix of Leadership. Tortured into accepting, Megatron was transformed into Galvatron, and his followers became Cyclonus, Scourge, and the Sweeps.

While Galvatron set about reclaiming leadership of the Decepticons, Unicron arrived at Cybertron, and proceeded to consume the planet's two moons. Outraged that Unicron would do this to a planet that he viewed as his, Galvatron found himself the victim of mental torture by his creator, and ordered to Earth to complete the task given him. The ensuing chase finally climaxed in a showdown on the planet of Junk, where Galvatron seized the Matrix and returned to Unicron, only to reveal that he intended to use the talisman to make Unicron his slave. Amused by his pawn's arrogance, Unicron transformed into his gigantic robot mode and ate Galvatron. Unicron then tore into Cybertron, as Shockwave and the rest of the Decepticons on the planet fought back, to little effect. Unicron swallowed many spaceships, and one, which contained the young Autobot Hot Rod and his comrades, crashed through Unicron's eye. Hot Rod and Galvatron battled deep inside Unicron, and ultimately, Hot Rod was able to retake the Matrix from the Decepticon. Transformed by its power into Rodimus Prime, he defeated Galvatron and opened the Matrix inside Unicron, destroying his body from within.

Unicron smash!

Unicron's head was blown clear during his death throes, and became caught in Cybertron's gravity, turning it into a new moon for the planet — a grisly testament to the satellites he had destroyed. The Transformers: The Movie

Incoming message from the Big, Giant Head!

In the year 2006, Cyclonus, Scourge and the Sweeps visited Unicron's head, seeking to locate Galvatron, who had been hurled into space at the conclusion of his battle with Rodimus Prime. As they trekked through the apparently dead Unicron, the Decepticons heard a low groan emanating from the head, which Cyclonus dismissed as the wind, despite Scourge pointing there was no wind in space. After accessing the remaining databanks and replaying footage of the final battle, Cyclonus extrapolated Galvatron's trajectory and current location. Five Faces of Darkness, Part 1

On the planet home to the monster known as Chaos, Astrotrain proclaimed that Galvatron would be "more famous in history than Unicron" once he destroyed Cybertron with his newly built death crystal cannon. Chaos

Unicron's glad he got that Triple-A membership.

Later, the ghost of the deceased Decepticon Starscream reactivated Unicron's head in order to make a bargain with him; in exchange for Unicron restoring his body, Starscream would recreate Unicron's. Stealing new optic circuits and a transformation cog for Unicron from Metroplex and Trypticon, Starscream was then directed to connect Unicron's head to Cybertron, so that the planet could become his new body. Starscream initially attempted to do this by using Trypticon's body, but Trypticon was deactivated by the Decepticons. Unicron restored Starscream's body so that he could finish the task, but Starscream (somewhat predictably, being Starscream) double-crossed Unicron and refused to complete the necessary connections. Just then, explosives set by the Autobots were detonated, hurling Unicron's head off the planet, beyond its gravity, and out into space. Ghost in the Machine

Seeking a supply of the dangerous particles known as anti-electrons, Galvatron and the Decepticons traveled to Unicron's head, only to come under attack from the defenses of the barely-aware giant. Also present was the Dinobot, Grimlock, who used components from Unicron's head to create the Technobots to fight Galvatron's forces. The Technobot Strafe disconnected enough of Unicron's internal mechanisms to deactivate his systems, apparently killing the evil giant. Grimlock's New Brain

While a much older Primacron mused about how his new creation, Tornedron, would succeed where "the other" had failed, the giant, damaged head of Unicron was visible floating along in the depths of space, where it had apparently faded to a dull grey. Call of the Primitives

Story of Binaltech

When Battle Ravage from the future came to be in early 2005, he initiated a plan to shunt most of the Decepticons outside of time, leaving the Autobots to face Unicron alone. Changing Lanes The future Decepticon also warned Shockwave, leader of the remaining Decepticons, of Unicron. However, Unicron was aware of the Decepticons' designs and used two Binaltech bodies stolen from an EDC shuttle for two obedient warriors, Blackarachnia and Decepticharge. The deity sent the duo to quell the Decepticons during an insurrection led by Starscream and order them to assist in destroying the Matrix. Widow's Edge Unicron met with Autobot troops when he attacked Cybertron. He destroyed many Cybertronians and devoured one of Cybertron's moons before Optimus Prime and Ultra Magnus left to confront the evil planet with the power of the Matrix. Darkest Hour Optimus was badly damaged during the journey to Unicron, leaving Ultra Magnus to infiltrate the titan's body alone. Though Ultra Magnus had not been chosen by the Matrix, he pleaded his case to the ancient artifact, and was allowed to unleash its power to destroy Unicron's body. Through further temporal machinations, the altered line of events instigated by Battle Ravage was preserved as an alternate timeline. Binal Time

Blackarachnia and Decepticharge, however, were still bound to Unicron's will and thus continued seeking to destroy the Matrix, but this threat was subdued. Outlier

Bwah ha ha ha ha ha ha ha ha

Following his destruction in 2005, Unicron's lifeforce was scattered across time and space, fragmented and parasitized into Autobot and Maximal leaders throughout history. In 2007, three of his servants, the Sparkbots, sought to recreate their master, and tricked the human singing group, the Kiss Players—Marissa Faireborn, Atari Hitotonari, and Shaoshao Li—into helping them in their task by telling them that they were gathering the fragments of the so-called "Allspark".

Oh god ha ha ha ha ha ha ha ha

Primus was forced to take action to stop their mission, appearing as a giant golden hand to steal away the energy fragments before the Sparkbots could collect them, but eventually, the evil trio collected enough to accomplish their dire task. Fleeing back in time to Earth's prehistoric past, they unleashed the energy and Unicron began to form around them. Following the Sparkbots back to the past, Primus unleashed the full firepower of his mobile battle platform's cannon, sealing Unicron's energy and the Sparkbots deep within the planet. He then created the mighty Brave Maximus to serve as a guardian and ensure that the evil being was never again reborn. Kiss Players #51 Sparkbots Volume 5

Unfortunately for everyone except Unicron, Brave Maximus would go on to leave the Earth in 2007, leaving the chaos-bringer's life-force unguarded. Kiss Players #39

YOU. DID. THIS.

In 2011, Unicron used the bodies of his disciples to build a new body and threaten the universe once again, forcing an Autobot-Decepticon alliance to try to seal him in the Triple Z Point. Super Megatron comic 1

By the time Unicron completed reforming, Convoy had undergone a quest to the Precursor World and returned with the power of Oracle at his side. Oracle was the original form of Primus from before the Big Bang, wielding the power of righteous Angolmois Energy to counter the corrupted Angolmois of Unicron. Assuming a gun form, Oracle blasted Unicron with his antithesis. This power was great enough to banish Unicron, sealing him in the Triple Z Point to end his threat. Finale

Unite Warriors

In 2021, Galvatron's ghost possessed Cyclonus, ordering him to take him to Unicron. The pair approached Unicron's remains, sealed away in the Triple Z Point, so that they could build a new body from Unicron's carcass. However Unicron was still conscious and far from powerless. He struck a deal with the two Decepticons; Unicron would reach out throughout the multiverse and pluck from their realities several 'bots who shared Galvatron's lust for revenge. Together, they would form a new "Grand Galvatron" body for the Decepticon leader, and leave Unicron's own body untouched. Galvatron agreed to Unicron's terms, and Roller, Thrust, and War Breakdown were brought to their universe. Starscream's ghost also turned up, and Unicron granted him a partial corporeal body to form the last component of Galvatron's new form. Unicron then ordered those before him to go out and conquer Cybertron in his name, but Galvatron was already scheming to betray his benefactor as he took off into space. Grand Galvatron Chapter

The prophecy was true...

Through Thrust, Trickdiamond contacted Unicron to strike a deal, agreeing to help him conquer Cybertron. Megatronia Chapter Before making his move, Unicron reached through time itself and recruited the Combatrons from the distant future to serve him. He reformatted his new troops into new bodies, then had his head travel back to Cybertron where Thrust and Trickdiamond provided him with the joint energon he needed to combine with the planet itself. As he began to transform Cybertron into his new body, Unicron took out Galvatron, announcing that he'd expected his betrayal and also that he would go on to destroy all Transformers, undoing the Combatrons' future. The angered Combatrons turned on him in the form of Baldigus, but Unicron pacified them by summoning his Matrix Hunter minion, Grand Scourge, who tricked Baldigus with his resemblance to Black Convoy. Ruination Chapter, Part One

As Unicron came closer to completely taking over Cybertron, cracks in space-time began to appear because of the many dimension-hoppers and time-travelers he'd brought over, forcing the Autobots and Decepticons to team up to defeat him and undo the cracks. While he was distracted by an attack from several combiners, Unicron's head was ripped out of Cybertron by Baldigus and thrown into space, where a barrage from the combiners and a mighty punch from Optimus Prime and Roller sent him flying back to the Triple Z Point.

With the Angolmois Capsules scattered across space, Unicron's servants, the Blentrons sought them out, to the point of taking them by force from the Maximals and the Predacons. Only Predacon Emperor of Destruction Magmatron realized their true intention: the resurrection of Unicron, eater of planet Dinosaur. Angry Magmatron The capsules were gathered at the Blentrons' hideout, where Unicron's spirit, free of the Triple Z Point, Fight! Maximals absorbed the Angolmois Energy to recover a physical presence. The energy "body" he took on was in form of the dead Galvatron, who had previously absorbed much of Earth's Angolmois Energy into himself. Magmatron confronted "Galvatron", and Unicron allowed the Predacon leader to believe he was his predecessor before defeating him and banishing him to another dimension. Unicron was soon confronted by the Maximals, who had pursued the Blentrons to their hideout, including Big Convoy, who realized the true identity of "Galvatron". Unicron Revived!? The Maximals took a tactical retreat and further ascertained Unicron's current state, while Unicron and the Blentrons set off to find more Angolmois Capsules. They found a horde at Advance Base 889T9, where they again met Big Convoy and his Maximals. The Maximals attempted to detonate the entire base in an effort to destroy Unicron, but he easily survived, absorbing the energy. Desiring a "complete body", he took his leave Unicron's Ambition to Cybertron, while he allowed his Maximal opponents to believe he was returning to the Triple Z Point for his original body.

Realizing the deception, the Maximals aboard the Gung Ho arrived at Cybertron, where they saw Unicron laugh at the compromise offered to him by Vector Sigma that he could be reborn as a regular Transformer. In a show of sheer power, Unicron absorbed the firepower of the entire Maximal fleet defending the planet and took the form of a blazing energy dragon to destroy it. Upon completing this task, he landed upon Cybertron, where he was confronted by Big Convoy, who attempted to use the deadly Mammoth Dynamite technique at full power to whittle Unicron away to nothing using super-oscillatory waves. However, he absorbed the three Blentrons to reconstitute himself. Attaining his blazing dragon mode again, Unicron broke into Vector Sigma's chamber to merge with the supercomputer and convert Cybertron into his new body. End of the Maximals!?

If you wanted to be pink, Unicron, you could've just impersonated Arcee.

Sending his crew away, Big Convoy attempted to stand against the full might of the Unicron-possessed Vector Sigma, but he was saved by his students, who refused to abandon their teacher. Magmatron, refusing to perish till he took his revenge on Unicron and became Predacon Emperor of the universe, returned to normal space and confronted Unicron in Vector Sigma's chamber. The Predacon seemingly destroyed the building and the supercomputer, forcing Unicron to return to using his energy body. Magmatron struck a decisive hit on Unicron, but his spirit simply drained Magmatron of his energy and sent him to another dimension again. Lio Convoy soon joined the battle and dueled with Galvatron while Big Convoy converted his Big Cannon into the Matrix Buster. Using the spirit of justice within all of his pupils and his Energon Matrix, Big Convoy fired the Matrix Buster at Unicron. Unicron attempted to absorb this energy, but the full essence of righteousness was too much for Unicron to handle and he exploded, finally ending his threat to the universe. The Final Battle

Apelinq considered the return of Unicron to be a less daunting challenge than a mandatory meditation session and lecture for the Cybertronian Knights by Alpha Trizer. Apelinq's personal log, 2015/01/07

Time-traveling to the future when Cybertron would theoretically be at peace and therefore unprepared for threats, the Star Seekers tried to use Unicron's head to drain all the energon out of Cybertron. A battle ensued aboard Unicron's head when the Cybertronian Knights arrived to stop them. However, the battle was prematurely ended when Alpha Trizer revealed to Star Seeker Captain Cannonball that Cybertron in 2984 was techno-organic and thus no longer operated on energon. Most of the pirates were then arrested, but during the battle Hunter was lured away by Unicron's voice to a transwarp portal that led into the past.

During Unicron's approach to Cybertron, Gong and Sideways began playing with universal streams, causing elements of a Gargent stream to interact with the Primax stream Unicron currently inhabited. As a result, many of the warriors Unicron reformatted for Galvatron were Renegades, including Deadlift (the tracker) and his Sweeps, Fracture (the warrior) and her armada.

Despite this, events unfolded much as they were meant to, culminating in the final battle between Hot Rod and Galvatron inside Unicron. Once Hot Rod claimed the Matrix and became Rodimus Prime, he unleashed its power and destroyed Unicron from the inside out. Echoes and Fragments

In a timeline where Optimus managed to kill Megatron during their final battle, Unicron nonetheless made his way toward Cybertron, pausing briefly to devour the dead and dying Decepticons thrown out of Astrotrain. He proceeded to Cybertron, where he interrupted Starscream's coronation. At the behest of Soundwave, Starscream flew out to bargain with the planet-eater. They reached a bargain: Starscream was upgraded into "Megascream", and his inner retinue of warriors were granted the ability to combine with their new leader, in exchange for Starscream's servitude.

Unicron eventually grew tired of his new herald's whining, and skipped chowing down on the Moonbases in favour of going straight for Cybertron, shrugging off Megascream's pleas.

Unicron is furious that he's been miscolored again.

Millions of years after Primus and Unicron entombed themselves inside planetoids and went their separate ways, circa the Earth year 1990 a group of Transformers discovered the sleeping form of Primus at Cybertron's core. When a battle erupted, a stray laser blast struck Primus, briefly jolting the god awake and causing him to emit a multiverse-shaking "Primal Scream" that alerted Unicron to Primus's location. Primus himself immediately slipped back into his sleep, but it was too late. The Primal Scream Bird of Prey! Knowing the severity of the situation, Optimus Prime approached an altar within the Ark, hoping to be granted a mystical vision which would guide him on his mission to stop Unicron. He witnessed the Creation Matrix being corrupted by evil in his vision, as well as Unicron's imminent encroachment! Kings of the Wild Frontier.

For over a decade, this was considered to be yet another one of Unicron's lies. But now it isn't. Gotta love retcons!

While devouring the planet Ghennix, Unicron took note of three criminals who were attempting to escape their fate. Unicron destroyed their vessel and recreated the three as Hook, Line, and Sinker. As the distance to Cybertron was vast and he was too large to teleport, he ordered them to retrieve a Galvatron from a possible future to serve as his herald. All Fall Down Though this Galvatron was angry at being plucked from his victorious timeline, Unicron tortured him until he agreed to be his herald. Still, this Galvatron secretly plotted his eventual treachery. Unicron sent all four of them to attack Cybertron and pave the way for his coming. Eye of the Storm

The looming threat of Unicron was so great that Optimus willingly surrendered his forces to Scorponok in a bid to unite both factions, and meet against the Chaos Bringer as a single force. Surrender!

So close to Cybertron he could taste it, Unicron decided to forgo consumption of the planet Jhi and hasten on his way to the ultimate confrontation. His herald Galvatron, however, captured Autobot leader Emirate Xaaron, forcing him to fully awaken Primus. Suspecting treachery on Galvatron's part, Unicron sent Hook, Line and Sinker to retrieve him from the subterranean tunnels of Cybertron, but Galvatron destroyed them, and Primus was woken from his slumber. Unicron's arch-foe possessed Xaaron's body and summoned Transformers from all across the universe back to Cybertron. Out of Time!

Unicron shut down his higher mental functions and drifted for the remainder of the journey to hide himself from detection by Primus. At this point, a mental command that Unicron had placed in some of Primus's creations was activated, resulting in the formation of a cult of Unicron-worshipers, who gathered to destroy the leader of the united Autobots and Decepticons. These Unicron cultists were drawn out when Optimus Prime was named commander of Primus's army. The cultists tried to assassinate the Autobot leader; they failed, but distracted the Cybertronians long enough for Unicron to sneak up on the planet. The Void!

He's got the whooooole world, in his feet...

After Unicron dug his fist into the planet and ate the flesh of his mortal enemy, he noted that this was the finest meal he had ever tasted. However, he was somewhat disappointed to find that the gathered Transformers were simply so terrified of him that there was no resistance to his attack. As he devoured Brainstorm from the tip of his finger, he admitted that despite their lack of showmanship, they were at least delicious.

Unicron's unchecked rampage was soon ensnared by Primus himself, speaking through Emirate Xaaron's body. For a short moment, Unicron was restrained, but when he deduced that this ruse was a big show put on by an insignificant portion of Primus's power, he broke free and destroyed the avatar of Primus, killing both Xaaron and his creator.

Galvatron, who was worried his treachery was going to waste, attacked Unicron, hoping his bravery would stir the Transformers into action. Galvatron was smacked down, but his gambit paid off as the Transformers snapped out of their collective stupor and began a counter-attack against the Chaos-Bringer. Countless Transformers died in this assault, including the Decepticon leader Scorponok. But Transformers weren't the only ones attacking him. Briefly fazed by the illusion-casting powers of the human Neo-Knight Rapture, Unicron's systems were attacked by the electrical powers of Circuit Breaker.

For soon you will have life. Sweet life.

After being clocked by the Ark, Unicron received another surprise: the thought-lost Creation Matrix had returned, along with its vessel, Thunderwing. Unicron was at first confused, as he'd sensed the Matrix's destruction, but quickly realized that the Matrix had not been destroyed, but had merely been masked by its seduction by evil. And in the realm of evil, Unicron had no equal! Thunderwing was destroyed, but the Matrix fell to the planet's surface.

Fighting the evil within the Matrix, Optimus Prime grabbed the artifact and launched into Unicron's maw, where the Creation Matrix was opened. While being pummeled by the flood of life unleashed by the Matrix, Unicron's body could not maintain structural integrity and exploded. On the Edge of Extinction! Still Life!

So, seriously, what was up with this stuff?

In an alternate 2005, Unicron's consumption of the planet Lithone was heralded first by strange pink mists^[1] that leaked from his planet mode's maw. On route to Cybertron, he encountered an injured Megatron and the bodies of his troops. He offered them new bodies in exchange for hunting down the Matrix. Though Megatron refused the offer at first, Unicron was able to persuade him by emitting more of his corrosive mist. Megatron was remade as Galvatron, and his troops were reborn as Cyclonus, Scourge, and the Sweeps. The Planet-Eater! As Galvatron was sent forward, Unicron devoured Moonbase One and Moonbase Two. Spike and Bumblebee detonated the latter satellite in an attempt to destroy Unicron, but the plan failed utterly, leaving Unicron completely unscathed. Judgment Day! Galvatron returned to Unicron with the Matrix, but he intended to use it to make Unicron his slave. In retaliation, Unicron attacked Cybertron in earnest, as the planet was helpless against his assault. Ultimately, during a battle that took place inside Unicron, Rodimus Prime claimed the Matrix of Leadership from Galvatron and the Planet-Eater was destroyed from within. Only his head survived, and it remained in orbit over Cybertron. The Final Battle! The Big Broadcast of 2006

In another alternate 2005, a dying Megatron was found by Unicron.

Later in Primax 490.0 Gamma, Unicron stumbled upon the Cybertronian Empire's Hub and savagely attacked. The Cybertronians fought back, rallying the remaining Autobots from Earth and Decepticons from Styx. Together, Autobot, Decepticon, and Cybertronian stood as one and destroyed Unicron's physical body. The Chaos-Bringer attempted to retreat to the psychic plane, but the Liege Maximo, at the height of his power, confronted him and sacrificed his spark to permanently expel Unicron from their reality.

However, Prime had his work cut out for him. With an attempted Decepticon alliance ruined beyond all recovery and the Matrix still lost, Optimus had to turn to the original site of the Underbase—as the Underbase was linked to the centre of Cybertron, the Autobots could tap into that centre (and thus Primus himself) as a substitute Matrix. The Magnificent Six!

And then Rodimus drove up through his entire body to escape through Unicron's other eye.

In a parallel timeline, Unicron did not arrive at Cybertron until the year 2006, consuming the small planet Lithone on his way. As he drew closer to Cybertron, Unicron came upon the damaged bodies of Decepticon leader Megatron and several of his Decepticon followers, who had been jettisoned into space following a major battle at Autobot City on Earth. Unicron extended Megatron a bargain, offering to rebuild him and his troops into new beings to serve him, and tortured the recalcitrant Decepticon leader into accepting. The Planet-Eater! Altered Image! Now reborn as Galvatron, Megatron immediately began scheming to destroy his "master", using a time-jump mechanism to travel back in time to 1986, where he constructed a solar cannon that was powerful enough to destroy Unicron's physical form. Fully aware of his pawn's actions, Unicron took control of the minds of Hot Rod, Kup, and Blurr and had them follow Galvatron back in time to foil his plan. Target: 2006

After Galvatron returned to 2006, Unicron devoured Cybertron's moons, much to his servant's dismay. Judgment Day! Unicron then attacked Cybertron while Galvatron fought Rodimus Prime within his master's body. Galvatron was defeated and thrown out into space. The Final Battle! He still had the remote to the time-jump mechanism and used it to travel back to 1986 again, where he planned to take over the Decepticons so he'd be ready for Unicron when he arrived 20 years later.

His head floated off through space to eventually crash-land on the planet Junkion. There, the still-conscious Unicron used mind control to force the native Junkions to build him a new body out of the planet. At the beginning of 2008, he pulled Cyclonus, Scourge and Death's Head into his thrall and used them to re-ignite the stalemated Cybertronian war in order to keep the Autobots distracted from his activities. Amused by Death's Head's repeated attempts at defiance, he told him about his origin, only to find himself now under attack by Rodimus Prime and an Autobot strike-team.

This almost went wrong, as Rodimus (at Death's Head's suggestion) tried to use the power of the Matrix on the astral plane. Here, however, the Matrix strengthened Unicron and the monster intended to merge with it for greater power. Ultimately, however, he was defeated by Wreck-Gar, who had planted explosives under the head's building site while the Chaos-Bringer was distracted. His head was destroyed, and his mind was sealed within the Matrix. The Legacy of Unicron! Space Pirates!

Rodimus rejects Unicron's endorsement of the coal industry.

On New Year's Day 2009, Unicron attempted to turn the Matrix towards evil and merge with it again, the only way he could bear being trapped within it. White Fire He reached out from within it and took control of Rodimus Prime's body, using him to sabotage an Autobot shuttle as it was headed for Earth. Kup caught on that Rodimus wasn't being himself quickly however, and forced Unicron to reveal himself earlier than the dark god had planned. Nonetheless, Unicron managed to force the ship into a crash-landing on Earth. As the dust settled following the impact, Unicron advanced on the Autobots, vowing to tear them limb from limb for their interference. Edge of Impact Regalling in the destruction, Unicron boasted that it was only fitting that the Autobots' end came at the hands of their leader. He further taunted them when he realized the Autobots had their blasters set to "stun," mockingly declaring that Rodimus was lost to them forever. Shadow of Evil Unicron's rampage was stopped when Kup ripped the Matrix out of Prime's chest. Unfortunately, this meant the Autobots lost their chance to purify the Matrix and that Unicron would be ready for them next time. White Fire In 2010, he repeated the trick and transformed Rodimus's body into a copy of his own before being forced back. In the far future of 2356, Unicron's essence still resided within the Matrix, steadily withering the struggling body of Rodimus. After a young student was influenced into seeking out Unicron, Rodimus realised Unicron was taking control again, and Unicron's voice chuckled "Soon"... Aspects of Evil!

When Starscream appeared on prehistoric Earth and was questioned by the stranded Predacons about how he came to be this way, Starscream "explained" that his body was destroyed by Unicron while serving his master, Galvatron.

After Unicron's entrapment in a lifeless, metal asteroid the dawn of time, Covenant the dark god recruited the Quintessons to seek out the location of his nemesis, Primus. But when the Quintessons discovered Primus, now having taken the form of the planet Cybertron, they decided to delay reporting their findings so they could first exploit Primus to their own ends. After finding the "singular threat" to Unicron and discovering how to subvert it, they used it to create a race of robotic beings which they could sell to other worlds for a price. Disclosure

Even Unicron's crap is evil.

After his destruction in 2005, while his head was left in orbit around Cybertron, Betrayal Unicron's essence was sent spiraling through time and space, to crash on prehistoric Earth, prior to the conflict known as the Beast Wars which would occur on the planet. It is unclear if this was a deliberate attempt by Unicron to preserve his power or not, but this "Dark Essence" seemed to lack any real sentience, suggesting that it was merely Unicron's "power", while his spark remained in his intact head in the future. Paradox

Unicron makes his own light saber noises.

The Dark Essence was discovered by a Predacon known as the Hunter, who recognized the dark god's power, and fashioned from the Essence the Matrix of Conquest, a twisted version of the Autobot Matrix of Leadership which he used to conquer and rule over an apocalyptic 32nd Century future, under the name "Shokaract". Resistance against Shokaract resulted in an attempt by his opponents to travel back in time and destroy the Dark Essence on prehistoric Earth, thereby erasing Shokaract from history, but the villain travelled back in time to stop this effort. A massive battle between him and Transformers from throughout the multiverse ensued, but eventually, thanks to the efforts of the Covenant, history was altered so that Unicron's essence never arrived on prehistoric Earth, erasing this timeline—and Shokaract—from existence. Terminus

Predicting that Unicron will eventually show up is a pretty safe bet, really.

Just after the Beast Wars ended on prehistoric Earth, the Vok assembled a team from the remains of that war to counter Tarantulas, Unicron's spawn. Primal Prime, the leader of the Vok's team, had visions of a future apocalypse, involving Unicron, that encompassed every timeline in the multiverse. Primeval Dawn Part 2 After Tarantulas ripped the Matrix of Leadership from Primal Prime's torso, he oversaw the construction of a transwarp portal that would allow him to bring his prize as an offering to Unicron. Primeval Dawn Part 3

One week after the Great Transformation, the Predacon gangster Cryotek succeeded in acquiring the Divine Light, one of the Quintessons' discarded attempts to subvert the will of Primus. As Cryotek used it steal Primus's power for himself, Sentinel Maximus warned him that flaunting Primus's power would catch the attention of Unicron and doom them all. Cryotek laughed at this, since Unicron had been dead since three centuries earlier, and the idea of his resurrection was a fairytale believed only by the naive. Wreckers: Finale Part II

Guys. GUYS. Get that ring in the right place, or he'll never be able to eat.

Cryotek was defeated, but one year later Unicron struck once more. His body ruined and trapped between universes, he sought to revitalize himself by abducting Transformers from across the multiverse and pitting them against each other within the Cauldron, a dark dimension contained within his own body, absorbing their energon radiation and eventually consuming their sparks. He chose to kidnap several Autobots and Maximals from one universe's technorganic Cybertron, but that was also the staging ground from which Primus chose to launch a counterattack. Primus gathered an army from many different universes and put the resurrected Optimus Primal at its head. Abduction Optimus Primal conducted his opening salvo by infiltrating the Cauldron and engineering a mass jailbreak. OTFCC Live-Action Drama Escape

That time Unicron was permanently destroyed across all universes forever, except the ones where he wasn't.

These "Children of Primus" raided Unicron to free his captives from their prison cities, battling Unicron's own legion of "Minions" all the while. These conflicts escalated for months or perhaps longer, their intensity rivaling the Great Wars.^[2] This all came to an abrupt end during the final battle, when Unicron simply vanished due somehow to the Unicron Singularity.

FOOLISH, DOOMED CREATURE.

Before the end of the Great War, the Tripredacus Council had set up a secret base of operations within Unicron's head. Though some of their members worried that they might awaken their "host" with their activities, the amount of Angolmois that had already been siphoned out of the satellite meant this was unlikely to ever happen. Unicron's head was later destroyed when the Tripredacus Council detonated their transmatter bomb. Dawn of the Predacus

Sometime after a series of events similar to those of Lio Convoy and Big Convoy's experiences on Gaia in another universe, Unicron's heralds, the Blentrons, were instructed by the Chaos Bringer's essence to gather the Angolmois Capsules scattered across the galaxy, which contained Unicron's energy. The taint of Angolmois would cause unrest and violence across Cybertron as the planet tore itself apart in renewed savage mindless conflict. At the same time, Unicron's chosen yet unwitting vessel, Shokaract, was fed Angolmois by the Blendtrons, having been convinced that it would grant him the power to be reborn as a god. In one potential timeline, this did indeed happen as Unicron was reborn from Shokaract's corrupted form, and the Chaos Bringer proceeded to consume Cybertron itself. The Ascending #1

However, this was averted before it came to pass—thanks to the actions of the in-temporal-limbo Magmatron, who alerted Ravage and by extension Lio Convoy to Unicron's plan and enlightened Shokaract when the tyrant was temporarily shunted into Magmatron's personal purgatory. Realizing what his ascension actually entailed, Shokaract tore the Anti-Matrix from his chest, sacrificing himself and ending Unicron's plan at re-ascension. The Ascending #4

Bom Bom comic continuity

After his destruction in 2005, Unicron's displaced lifeforce became trapped within the planet Earth, where it was eventually discovered and manipulated by humankind (who were unaware of its origins). This resulted in the devastation of the planet, but the fame of this "mysterious energy" that had been called "Angolmois Energy" was far-reaching, and eventually, twenty million years after Unicron's destruction, Double Cross the Predacon leader Galvatron travelled to the deserted Earth (now known as Gaia) and attempted to harvest it for himself.

A Maximal energon survey team was sent to the planet Unicron, but it lost contact with Maximal Army Central Headquarters. Demolish the Superdreadnought Tank!

Galvatron eventually succeeded in sucking-up all the Angolomois energy on Gaia into his artificial planet Nemesis. All Hands, Make a Special Attack on the Evil Planet! The Maximals journeyed to Nemesis to stop him, only for Lio Convoy to become corrupted by the Angolmois Energy, turning a Predacon.

He then used that same power to destroy Nemesis, the Angolmois Energy, Galvatron and the Predacons. Win the Battle of Light and Darkness!

The explosion of Angolmois Energy wound up creating new problems, transforming a small group of dinosaurs into the Predacons led by Magmatron. As they left their homeworld in search of the lost Angolmois Energy, a mysterious, supernatural figure (Unicron) looked on in interest. The Beast Wars "Neo" Begin!!!

"Reply hazy, try again"

On the planet Gaia, a group of Predacons somehow came into possession of a mysterious spheroid object known as the Black Ball. The strange artifact was of some importance to the Predacons; it may in fact have told Magmatron that he could rule the galaxy once he had the seven Angolmois Capsules.

*Head not to scale

When Big Convoy came to rescue five Maximal rookies who were trapped in the Galvaburg II on Gaia, the Maximals found the Black Ball and retrieved it.

After the Maximal returned to the Gung Ho, they attempted to analyze the Black Ball. However, the Black Ball activated the ship's warp engine. The 5 Rookies During the warp, the Black Ball began to speak, telling the Maximals about the Angolmois Capsules, which originated from the final conflict between Lio Convoy and Galvatron on Nemesis. It also told them that there were seven Angolmois Capsules scattered across the galaxy in total. The Maximals were warned that they must retrieve all the capsules to prevent them from falling into the wrong hands, or the galaxy would be in extreme danger. The Gung Ho subsequently arrived at the planet Luxor, where one of the capsules was located. There Are 7 Capsules

The Black Ball guided Big Convoy's team to various other places where capsules were located.

When Magmatron, who was in a healing chamber in the Dinosaur due to wounds caused by Big Convoy, learned that he lost his troops in the battle on Jörmungandr, the Black Ball suddenly appeared. The Black Ball told Magmatron that it could see he was short-handed and offered Magmatron some "helpers"—the Blentrons, who emerged from within the Black Ball. A Battle Fought Alone

The Black Ball told both Big Convoy and Magmatron of the planet where the last capsule was located. Magmatron faced off with Big Convoy there, and ordered the Blentrons to attack the Maximals. One of the Blentrons, however, chose to attack Magmatron instead. The action of the Blentrons baffled both Big Convoy and Magmatron alike. The Black Ball then arrived on the planet's surface.

It was revealed that the Black Ball was actually Unicron himself, or more specifically, his essence, while the Angolmois Energy was his life force. Unicron absorbed the six capsules and reformed his head out of the Black Ball. He then revealed that the last capsule was actually both Big Convoy and Magmatron, who were evolved by the power of the Angolmois Capsule on their home planet in the 7th Cosmos.

"Hey kid, wanna buy some wow?"

Big Convoy teamed up with Magmatron to fight against Unicron, but both failed. Big Convoy was saved by Heinrad, who told him about Unicron's existence and the plan of the Ruler of Time and Space—to erase the universe and create a new universe without Unicron, the "cancer". After Heinrad was forced to leave due to his interference, Magmatron was chewed up and spat out by Unicron.Double Cross Unicron then headed to the planet Cybertron. He latched onto the planet like a parasite and turned it into his new body.

Unicron desired to consume Big Convoy, the last half of the capsule, in order to make his right eye fully functional once more. His physical body was destroyed by Big Convoy after a harsh battle with Big Convoy's crew. However, Unicron's essence emerged from his physical remains and plastered itself onto Big Convoy's body, trying to possess him. Big Convoy removed the Matrix from his chest and unleashed its power, sacrificing himself and successfully destroying Unicron once and for all. Return to Zero

Long ago, Unicron threatened Cybertron, and Solus Prime developed powerful tools to help defend against him, such as the Matrix of Leadership, the Enigma of Combination and the Requiem Blaster. The Fight Begins Ultimately, Megatronus used the Blaster to finally defeat Unicron, leaving his destroyed head helplessly floating through space.

First appearance: The Transformers #31 (mentioned); First Strike #6 (depicted)

"As you can see, our artist's rendition matches the suspect right down to the, uh, number of limbs."

From the earliest days of the species, Cybertronian legend spoke of Unicron—a name that translated to "uncreator"—Unstopped and Unstoppable and, according to myth, the diametric opposite of the mythological Primus. All Good Things Some religious circles considered the two beings as natural balances to one another; the Clavis Aurea sect believed that Primus had formed as a "counterbalance" to the uncreator. You, Me, and Other Revelations Metastasis According to these myths and legends, Primus battled against this villainous being for eons in a war that predated the universe before eventually triumphing over his foe and casting him out. Last Stand Another account claimed that the original three Titans—Metroplex, Metrotitan, and Chela—had taken part in the battle. Origin Myths

Despite this, the myths held that the uncreator would one day return, and only the hero known as the Arisen could slay the devil once and for all and bring peace to the universe. Last Stand In Cybertronian society, the uncreator was generally referred to only as "Primus's opposite". All Good Things You, Me, and Other Revelations

You can juuust spot the Collector base on the edge.

Unbeknownst to the majority of the Cybertronian species, this dreaded being would soon become more than a mere myth thanks to the machinations of a time-travelling Shockwave in his quest to ensure the perpetual dominance of the Cybertronian species. Disguised as "Onyx Prime", Shockwave had encouraged his fellow members of the Thirteen to begin an age of interstellar expansion and spread the Pax Cybertronia across the galaxy, and the first planet to be targeted for colonization by Cybertronian forces was a planet that lay close to the galactic core: the organic world of Antilla. Though the Antillans fought back, they were unable to match the power of Omega Supreme and his Omega Sentinels, driving them to the brink of extinction. Stranger Eons

As the war tipped in favor of the Cybertronians, a desperate Antillan, bereaved by the loss of his family, constructed a doomsday weapon that would end all life on the planet, organic and mechanical alike. Ceremony When activated, the device's energies did just that and more, collapsing Antilla's sun into a black hole, cascading across space and time to wreak havoc on far-flung worlds—and remaking Antilla itself into the ultimate weapon of retribution against the sins of the Cybertronian race. Stranger Eons Shockwave had foreseen this result; by one day unleashing "Unicron", Shockwave reasoned that he could use the monster planet to wipe the slate clean; by destroying Cybertron itself, he could free his species from the religious wars and factional violence that plagued his homeworld, and begin the construction of a new Cybertronian empire by conquering another world elsewhere in the galaxy. As the Talisman's magical energies were anathema to mechanical life, Shockwave reasoned that he could simply do away with his monster the moment it no longer served his needs by tricking it into swallowing the Talisman, which would kill him from the inside out. Road's End

His mind still tied to the "Talisman" that had birthed him, Unicron remained dormant for millennia; Onyx Prime would return to the wastes of Antilla shortly after the First Cybertronian Civil War and excavate the Talisman, Our Finest sending it to Earth aboard the starship Axalon for safekeeping until the day it would be needed. Strange Visitors

At some point in the past, the Matriarch of Incendium and her Camien retinue briefly visited Antilla, and an inexplicable and violent confrontation with "Onyx Prime" and his Maximals led her to fear that the dead world had been the domain of Primus's opposite... a statement closer to the truth than she realized. Surfeit of Primes

Following the end of the Great War, Optimus Prime wondered if Cybertron's primordial landscape was a creation of Primus or his opposite. The Death of Optimus Prime

Spoiler alert: Matt Trakker is gonna be the one that kills him.

After twelve million years of dormancy, Unicron was unexpectedly activated, not by Shockwave, but by the Prysmosian wizard Merklynn, who believed that the Talisman could recreate his lost homeworld. When he unleashed its energies deep beneath Cybertron during his creation of New Prysmos, his magic somehow prompted Cybertron itself to burn through half of its remaining energon reserves and beam a simple message into the depths of space: a communication signal that translated to "Welcome. Death." The message reached its intended target, and Unicron awoke to carry out his ancient mission, his metallic form bursting free from Antilla's rocky exterior. First Strike #6 The Talisman sent a second message to Unicron during the brief conflict between the Cybertronians and Prysmosians; when Galadria's healing spell interacted with Wheeljack's anti-Talisman bomb and the Talisman itself, the artifact beamed another message into deep space, this one simply reading "Unicron", bestowing the legendary name onto the monster planet. A week later, Merklynn used his magic to foresee Unicron's imminent arrival. The Curtain Our Darkest Unstopped and Unstoppable Historia

Unicron's first act upon awakening was to devour the massive black hole that his planetary form had once orbited; by absorbing and harnessing the quantum-tunneling properties of the black hole, Unicron was able to draw energy from nearby stars to fuel his apocalyptic assaults and effectively snuff them out with each world he devoured. Assembly Survivors of Unicron's later attacks would record this phenomenon as "the stars going out" each time Unicron successfully consumed a planet, unaware of the existential threat this posed to the stability of the galaxy. Our Darkest

He's eating them. And then he's going to eat me. Oh my goooooooooooooooooood.

Seemingly driven by the ancient desire to destroy every world affiliated with the Cybertronian species—the thirteen colony worlds, each seeded with one of Shockwave's Regenesis ores—Unicron's second target was the time-tossed world of LV-117, consuming it to feed on the Ore-1 responsible for its unusual temporal properties. As a result of these temporal distortions, history would record the planet as having been destroyed sometime in or around the year 2012. Syndromica (2) Our Darkest Unicron then began his assault on the galaxy in earnest, moving onto other ore-seeded colony worlds—Prion, then Gorlam Prime, then Velocitron, absorbing their mass into his, each extinction increasing his size and power and accelerating the pace of his attacks. Our Darkest Unstopped and Unstoppable His insides assimilated and recombined every planet he consumed into a single surreal landscape, all still "alive" in some form. Their inhabitants, similarly assimilated and fused together, became an "immune system" to fight off invaders. Last Stand

A week after consuming LV-117, the presence of Ore-12 drew Unicron to Elonia. He swiftly devoured the planet, annihilating the contingent of Space Knights that flew out to confront him with a single blast from his maw, though Transformer intervention saved two-thirds of its fauna and population. Elonia was swiftly devoured, and as the stars faded Unicron teleported himself over Eukaris to begin his next attack, reducing the planet to rubble, Our Darkest and absorbing its supplies of mutagenic Ore-11. Ceremony After consuming Eukaris, Unicron devoured Arduria, Tsiehshi, and Devisiun, Shockwave's army of Maximals joining him at the last one to chase away the Peaceful Revolution. Prowl was able to use the movement of Maximals across the galaxy to predict where Unicron would strike next, however, and determined that his next target would be Caminus. Unstopped and Unstoppable

Over there you'll find Gepetto's ship, over there you'll find Jonah, and over there you'll see Marlin and Dory...

Unicron arrived over Caminus shortly thereafter, with the Maximals swarming over Optimus Prime's hastily assembled armada while Unicron himself began consuming the planet. As the Titan Nemesis docked on his surface, Bumblebee used his starship to ram a hole through the Titan's alternate mode and into Unicron, allowing himself, Prime, and Arcee to enter the Chaos Bringer in the hopes of finding a way to destroy him from within. The trio discovered the amalgamated nature of his interior and discovered a ruined Omega Sentinel, a relic from the war that had precipitated his creation, before being beset by Unicron's antibodies. The three were rapidly overwhelmed and forced to teleport out, having learned nothing of use. Unicron devoured Caminus shortly afterward, swallowing up the Maximals who had terrorized the Camiens in the process, though the populace managed to evacuate in time. Last Stand

"Destiny. I... destroy... your... DESTINY!!!"

As he sailed past G Nebula 89, Unicron was confronted by the Decepticon Vengeance Division, a fleet of Decepticon warships each capable of destroying planets on their own. The fleet established a stasis web around the Chaos Bringer to prevent him teleporting away before they unleashed their full might against him. Unharmed by the D.V.D's assault, Unicron regurgitated the Maximals—now mutated by exposure to Ore-11—to meet with Bludgeon, who sought to embrace chaos by serving Unicron and the Maximals. Unicron teleported away once more, leaving the stars to go out behind him. Stranger Eons

His constantly-mutating body re-energized by the infusion of a Cybertronian transformation cog supplied by Nemesis's corpse, Unicron developed a new power: the ability to assume a towering robot mode, and it was in this form he appeared in above Cybertron, ready to complete the final stretch of his mission. Stranger Eons Road's End Before the Cybertronian fleet could engage him, Unicron deployed the Decepticon Vengeance Division, now warped and mutated by Ore-11, to engage this obstacle. Shockwave believed that his plan had come to fruition: thanks to the efforts of the Visionaries, the Talisman was now on Cybertron, and when Unicron consumed Cybertron, the energies of the Talisman would destroy him along with the Transformer homeworld: "uncreating the uncreator". When the DVD finally cleared a path through the resistance, Unicron dug his talons into Cybertron, preparing to kill the planet and its occupants... all proceeding according Shockwave's plan. Our Finest

As Unicron began his latest assault, Council of Worlds representatives convinced the inhabitants of New Prysmos to use the Talisman's magic to teleport the populace of Iacon to safety, projecting a ribbon of energy that teleported all it touched to faraway Earth. Unicron attempted to prevent the Cybertronian fleet from reaching the magical ribbon only for Elita One to ram the totalled Carcer into his face, distracting him long enough for everyone to escape his immediate grasp. In a rage, Unicron unleashed his full might on the planet, releasing a burst of energy from his chest as he ripped Cybertron in half, effectively destroying the Transformer homeworld. Unbeknownst to Shockwave, who had already teleported himself to Earth, his grand plan had failed: Prime's evacuation efforts had brought the Talisman itself to Earth, leaving Unicron free to follow the Transformers to the planet and complete the extinction of the Cybertronian race.

Indeed, after his destruction of Cybertron, Unicron teleported himself into the Solar System to destroy Earth and what remained of the Transformer species; ploughing through Jupiter and obliterating Sanctuary Station, Unicron and the D.V.D., now wholly loyal to Unicron's mission of extinction, began their final approach over Earth, Road's End his mere arrival causing gravitational havoc on a planet-wide scale. Road's End Time Will Rust Reunion

Shockwave was unaware that Unicron was more than a simple eating machine, however; Unicron was intelligent enough to realize that the Talisman was now on Earth, and the planet's destruction would also lead to his destruction. At the same time, Bludgeon and the Maximals revealed that they were now loyal to Unicron instead of Shockwave, leading a search for the Talisman so that Unicron could safely devour Earth. As events came to a head, the united armies of Cybertron, and her colonies led a battle against Bludgeon's forces, while Skywarp, Thundercracker and Starscream, engaged on a covert mission of their own: smuggling Prime, Arcee, and the Talisman towards Unicron, in the hopes that Skywarp's teleportation powers could instantly transport the device into the heart of Unicron. Assembly

This is what happens when you eat sugarless gummy bears.

Unicron took part in the ensuing battle, blasting Trypticon in half with his eye laser, unaware of the drama playing out on his surface; with Skywarp wounded, Starscream sacrificed himself to activate the Talisman so that its energies would drill down to the core of Unicron. Prime and Arcee followed it down until they came upon the very heart of Unicron: the black hole that he had once orbited and swallowed up. Realizing the only way to kill Unicron, Prime hurled himself into the black hole, and wound up in infraspace; there, he encountered the specter of Unicron's creator, still desiring vengeance upon the Cybertronian race. Ultimately, however, Optimus was able to convince the ancient alien of his good intentions, and his desire to stop the cycle of violence that Shockwave had perpetuated all those millennia ago; embracing the scientist, the pair died together.

In doing so, Unicron's physical form collapsed into the black hole at his core. The black hole would remain in the Solar System, visible from Earth as a monument to the battle. Ceremony

I'm advertising a toy you can't buy!

Unicron was a being older than recorded history and a devourer of worlds, and was a myth to Cybertronians, much to his content. Kingdom episode 6

After a nearly endless war that resulted in the AllSpark parting from Cybertron for good, Kingdom episode 1 Megatron killed Optimus Prime, lamenting that they should have worked together. Afraid of the possibility of unity, Unicron enslaved and reformatted Megatron and Optimus Prime into stronger bodies but in lives of servitude as Galvatron and Nemesis Prime, as recorded at the end of the Voyager Golden Disk. Kingdom episode 5 Unicron observed Galvatron's every move, swiftly torturing the ‘con if he even looked at the AllSpark. As the Autobots and Decepticons died out, Unicron and his minions were a constant threat to the Maximals and Predacons that emerged from the uninhabitable Cybertron.

Using the Dead Universe to time travel, Kingdom episode 6 Galvatron first attempted to stop his predicament by meeting his younger self on the Nemesis. However, his attempt failed and Unicron found his wayward servant, painfully pulling him back to his proper time and promising severe punishment. Earthrise episode 5 Unicron avowed that Galvatron could not save himself from the inevitable, shortly before his minion stated otherwise, pushing himself away. Kingdom episode 1 In another desperate attempt to break free from his master, Galvatron allowed Predacon Megatron to travel to the past and deliver the Golden Disk to the original Megatron, out of hopes he will listen to it and avoid his altercation with Unicron. Kingdom episode 6 While unconscious after the Nemesis crash, Megatron had a premonition of Galvatron's return to Unicron. Kingdom episode 1

Ah, so that's why SkeliVORE was in the spoiler pack!

After Starscream stole and listened to the Golden Disk, he bore witness to Unicron enslaving Megatron, reformatting him into Galvatron. While belittling Megatron for his unfortunate future, Unicron, within Starscream's mind, spoke directly to the Seeker, drawing the Decepticon into his maw, traumatizing him. Starscream, not confident enough to stop Unicron, fled to Bumblebee to give the Autobots the Golden Disk while rambling on how Unicron staged the Cybertronians’ endless conflict. A far more capable Starscream later stopped Megatron from destroying the Ark, believing that the Decepticon leader was fulfilling Unicron's desires. When the conflict finally seemed over, and the Ark launched to Cybertron, Starscream agonized knowing the Cybertronians’ return is what Unicron wanted. Kingdom episode 5

Galvatron and Nemesis Prime attempted to destroy Unicron by coercing Megatron to use the AllSpark against him at the cost of Cybertron, though they were defeated. After the Cybertronian conflict was finally resolved, Starscream worryingly noted that Unicron was displeased, though Blackarachnia reassured him that they will be ready, should he show himself. Upon Galvatron and Nemesis Prime's return, Unicron berated their foolishness in using the Dead Universe to time travel but mused that it had given him ideas. Opting to "begin again", Unicron drew his minions into his maw, torturously reformatting them. Kingdom episode 6

In one of several possible futures, Unicron attacked Cybertron in the year 2005. However, as the Matrix of Leadership had been destroyed along with Optimus Prime millions of years prior due to the time-travelling machinations of Megatron, it was uncertain whether the Decepticons would be able to actually stop him.

Before the formation of Cybertron, Unicron and Primus battled fiercely, their blows shaking the very foundation of the cosmos. A group of Transformers then appeared, time-displaced from the distant future. Galvatron and his Decepticons joined forces with Unicron while Rodimus's troops helped Primus. Unicron was defeated despite being able to will more beings into reality. Battle of the Brothers

A slightly different looking Unicron loomed over a bird-like version of Blaster, on a page promoting the game's Facebook, this has since been replaced by a picture of Megatron.

The same Unicron can also appear in the background in some of the levels, where he will fire flaming balls at you while also shielding himself with a force field, similar to the one granted by using the Energonicon Shieldor. Which will disappear after a while, leaving him open for attack.

Transformers: Devastation

As Unicron slept, the Mission of Cybertronian Expansion ship, the Proudstar touched down on his surface. He observed the crew members and eventually corrupted them to varying degrees, particularly their leader, Nova Prime. His influence caused them to begin cyberforming inhabited worlds as well as uninhabited ones, wiping out millions of lives. Before the Proudstar left, Nova pointed Unicron in Cybertron's (and Primus's) direction. The more distance the crew put between themselves and Primus, the more Unicron managed to corrupt them. Kranix and Jhiaxus separately realized what Unicron had done to them but could not stop it. Kranix eventually caused the ship to crash into Earth before he fled to Lithone. Unicron, meanwhile, followed the trail of cyberformed worlds, destroying all he came across in the process. Millions of years later, a touch of his darkness still permeated in the Proudstar. Optimus Prime felt him through the Matrix. Teletraan Alpha seemed to know that Unicron represented chaos but not who he was.

Transformers Roleplaying Game

In ancient times, the Thirteen are said to have protected the AllSpark from Unicron's corruptive influence. Field Guide to Action and Adventure Although many Transformers lived in terror of the prophecies that foretold a day when Unicron returned, other Cybertronians saw the "Unicron Singularity" as a necessary catalyst for change in a random and ever-shifting universe. These "Followers of the Word of Unicron" were primarily Decepticons; however, the philosophy caught on among the Junkions and even some adventurous Autobots.

When Unicron returned and attacked Cybertron, the war for Cybertron became a war between those Transformers who fought to defend their homeworld against those who allied with the planet-eater. During this crisis, Megatron was eventually reborn as the more powerful Galvatron. The epic battle killed many Transformers, and in the end Unicron was destroyed and his parts scattered to the cosmos, leaving only his head in orbit around the planet. In the aftermath, the defeated Decepticons fled to planets like Chaar and New Kaon, although some followers of Unicron revered his remains, confident that he would one day rise again. Decepticon Directive

Notes

 

"Ingestor" sure evinces Bob Budiansky's lack of involvement with the film.

• Unicron was created by writer Ron Friedman as the main antagonist of The Transformers the Movie. As recounted in his autobiography, Unicron was meant to be the "personification of a selfish destructive force" and was intended as a threat that would force both the Autobots and Decepticons to unite against him in order to survive.
• In the first draft, Unicron was known as the Entity. In this draft, The Entity was a ghostly voice that served as "the absorber of Unicron", a hellish, "slab-like mechanical planet" seemingly covered by iron grass and steel trees which turned out to be the hairs of his humanoid form. The planet was also coated in metallic scales which his rebuilt servants share. The Entity appears to be the master of the planet, communicating from somewhere within. Only at the draft's climax are The Entity and Unicron revealed to be one and the same, when he gathers enough energy to transform into robot mode.
  • Similar to the final film, the dying essence of Megatron was rebuilt into Galvatron (and only him at this stage). The Entity then orders Galvatron to convert all of Cybertron into his servants and destroys the planet after doing so. Absorbing the planet allowed Unicron to grow larger and more powerful. After this The Entity commands his troops to head to Earth to drain the planet. When Galvatron attempts to escape the Entity's control he threatens to destroy Unicron by sending a "Thermo Charge" all the way down to the planet's core. This inadvertently provides the final piece of energy he needs to transform. He then heads to devour Earth. Only at the end is he stopped when the Matrix is opened ..... by Daniel and he's torn apart in a "hurricane of light".
  • That probably doesn't sound too far from the final film, but the major difference was his backstory. The final film doesn't give him one. In this draft we learn that The Entity was created by the ancient Junkions to serve as their Protector and "maintain loving watch over all". However he was corrupted by jealousy and power. Their planet became Unicron's moon and the current generation of Junkions now live hidden from him.
• In the second draft, Unicron's backstory would be dropped. Hasbro also specifically requested that his dialogue be kept to a minimum as they found a 'talking planet'"somewhat of a stretch". Anyway, Friedman completely ignored that.
• For the second draft The Entity was renamed Ingestor. Here he would remake the Life Spark of Megatron and other fallen Decepticons into Galvatron and his troops, and once again have them gather energon to feed the planet (consumed with straw-slurping and lip-smacking sounds). The twist of him and Unicron being the same was kept as was the planet's description. At the end of this draft, Unicron is completely destroyed by the Life Spark of Optimus Prime.
• Friedman's handwritten notes on the second draft outline reveal several other potential names: Absorber, Unitron, The Amalgamator, Amalgamon and Masticar.
• Character designer Floro Dery claims his designs for Unicron were very large and complicated. For example, there were three drawings of Unicron's internal organs that were 2'x7' each. Dery also explains that Unicron's television monitor-covered core is "like security monitors in a building," and that he must watch these screens manually to know what is going on, rather than the information being diverted directly into him from the screens' source. And finally, the orbiting moon that is seen in the discarded Generation 1 prototype by Takara (see Unicron/toys) was intended to be "a kind of mini-Unicron, like Mini-Me of Dr. Evil." Floro Dery's kind of eccentric.^[6]

That's no moon. No seriously, ignore that moon.

• Floro Dery's production notes as shown on his designs for Unicron (then "The Entity") depict elements from the first draft of the original film that were dropped in the final film, or stuff he made up because he thought it would be better(he has admitted to doing this):^[7]
  • The spheres on Unicron's rings are meant to be roughly equivalent in size to Earth.
  • The surface of Unicron was originally a dense jungle of metal and mechanical creatures.
  • Dery's roundabout reasoning for giving Unicron rings is explained: "Saturn sounds like Satur [presumably meaning satyr]. Satur is synonymous with the Devil. The Entity is a Devil-like planet. This is the reason why I designed the Entity like the planet Saturn."
  • A moon is included (as in Takara's Generation 1 toy prototype), but never explained aside from being flashy and conductive. Scenes involving "The Satellite Moon of Unicron" exist in very early drafts of the movie, but were moved to a planet that would become Junkion in later drafts.
  • All the circular portions on the planet's surface were to flash and reflect different colors to "dazzle the viewers" and eliminate the epileptics in the audience.
• The earliest known Dery sketch of Unicron gives him somewhat pronounced "nostril" slots, which is a detail that was eliminated on subsequent character model sheets... but still shows up in certain AKOM animated episodes, particularly "Ghost in the Machine". Weird.

He shaved!

• An earlier version of Unicron's head showed up during Unicron's transformation scene in The Transformers: The Movie. Originally animated for The Transformers: The Movie promo, this version has no facial hair and has extra greebles all over his face. It also colored the helmet entirely gray, save an orange mohawk. This design of Unicron was modeled by Satoshi Urushihara. In IDW's comic book adaptation of the animated film, Don Figueroa drew a hybrid between the two designs, combining the facial hair and the orange mohawk.
• The Movie and the following season of the cartoon are extraordinarily consistent about Unicron never actually moving his mouth while speaking, suggesting his voice may be broadcast as opposed to physically produced.
• Unicron's profile in The Transformers Universe states that Unicron eating planets (and stars) increases his size and his hunger, a detail that first appeared in fiction in Unicron #0.
• Unicron's appearance in the Legends comic is drawn like a Battle Changer-type Kreon in order to make him larger than the average Kreon. His construction appears to be specifically based on Battle Changers Bumblebee's, and he also wears Bumblebee's helmet.
