Editing Unicron (section)

===''The Transformers: The Movie''===
The character Unicron first appears in the opening scene of 1986's ''[[The Transformers: The Movie]]'', immediately making clear his goal by consuming the small world of Lithone. Subsequently, when the Decepticons [[Megatron]], [[Skywarp]], [[Thundercracker]], and the [[Insecticons]] are set adrift in space and left to die following a furious battle with the [[Autobot]]s, Unicron appears before them and offers Megatron a deal: in exchange for a new body, and new troops, Megatron will destroy the Autobot [[Matrix of Leadership]], the only thing that can stand in Unicron's way. Thus, Unicron rebuilds Megatron into a new and more powerful body and rechristens him [[Galvatron]]. He then uses the battered bodies of the other Decepticons and creates Scourge, the Sweeps and [[Cyclonus]].<ref>{{Citation |title=Transformers Unicron meets Megatron and his transformation into Galvatron | date=11 July 2009 |url=https://www.youtube.com/watch?v=hzNsOGt3bHk |language=en |access-date=2022-12-11}}</ref> Unicron also gives Galvatron a vessel, and Galvatron begins to carry out his assigned task, although he is loath to do so. When Galvatron shows any signs of opposition to Unicron's will, Unicron inflicts agonizing torture in his mind to coerce him into obedience.

Following Unicron's consumption of Cybertron's two moons, Galvatron obtains the Matrix from [[Ultra Magnus]], believing he can use it to bring Unicron under his control. Attempting to open the Matrix to intimidate Unicron, Galvatron only prompts his transformation into robot mode and is swallowed by the planet-eater. Unicron lays waste to Cybertron, halted briefly when the young Autobot rookie, [[Hot Rod (Transformers)|Hot Rod]], crashes a [[Quintessons|Quintesson]] spacecraft through his eye.<ref>{{Citation |title=Transformers G1 The Movie The Autobots Attack Unicron | date=November 2015 |url=https://www.youtube.com/watch?v=IWJsbIKsif8 |language=en |access-date=2022-12-14}}</ref> Finding Hot Rod inside Unicron's body, Galvatron suggests an alliance against their common enemy. However, Unicron inflicts his mental torture upon Galvatron, forcing him to fight Hot Rod. Hot Rod seizes the Matrix from Galvatron during the fight and becomes Rodimus Prime. Rodimus throws Galvatron into space, freeing him from Unicron's mind-control. Rodimus opens the Matrix within Unicron, destroying his body, leaving only his head, which becomes a moon of Cybertron.<ref>{{Cite book | title=Transformers: The Ultimate Guide | last=Furman | first=Simon | date=2004 | publisher=DK Publishing Inc.| isbn=1-4053-0461-8 | pages= 40–51}}</ref>

Unicron was voiced by [[Orson Welles]].<ref>{{Cite web|title=Welles' last role?

"He came in... and said, 'I'm playing an entire planet!'" Dille recalled on a DVD of the film released last year.}}</ref>

The third season of ''The Transformers'' animated series continues Unicron's story where the movie left off, as the planet-eater's deactivated head settles into orbit around Cybertron. His head is visited by Cyclonus, who accesses the memory bank to discern the fate of Galvatron.<ref>{{Citation |title=Five Faces of Darkness, Part 1 {{!}} Transformers: Generation 1 {{!}} Season 3 {{!}} E01 {{!}} Hasbro Pulse | date=11 September 2021 |url=https://www.youtube.com/watch?v=Rp7qxd3c31s |language=en |access-date=2022-12-11}}</ref> Later, the ghost of the deceased Decepticon [[Starscream]] reactivates Unicron's head and enters into a bargain with him, performing three labors in exchange for the restoration of his body. Starscream (inhabiting and controlling Scourge's body) gathers for Unicron [[Metroplex (Transformers)|Metroplex]]'s eyes (breaking one<ref>{{Citation |title=Generation 1 - 80 - Ghost in the Machine 1/2 HD | date=3 October 2010 |url=https://www.youtube.com/watch?v=Ne2fwp53ZTo |language=en |access-date=2022-12-11}}</ref> and replacing it with one from [[Trypticon]]) and Trypticon's transformation cog. He begins to connect his head to Cybertron, which would become Unicron's new body. Starscream demands that Unicron restore his own body so that he can complete the required connections. Once Unicron does so, Starscream double-crosses him and refuses to finish the job.<ref>{{Citation |title=transformers episode 81 - ghost in the machine part 3 | date=16 February 2008 |url=https://www.youtube.com/watch?v=j8QUF0c5Qzk |language=en |access-date=2022-12-11}}</ref> Unicron's head is subsequently blown off into space by an explosion instigated by the Autobots.<ref>{{cite episode |title=Ghost in the Machine |series=The Transformers}}</ref>

Later, when searching for a new supply of positrons (anti-electrons), the Decepticons venture to Unicron's head, where Cyclonus and Scourge accidentally awake the slumbering demi-god. At the same time, [[Grimlock]] constructs the [[Technobots]] from pieces of Unicron's head,<ref>{{Citation |title=Birth of the Technobots (Computron Merge!) | date=3 March 2018 |url=https://www.youtube.com/watch?v=CvCnt4X0CDg |language=en |access-date=2022-12-11}}</ref> and one of their number, [[Strafe (Transformers)|Strafe]], severs enough of Unicron's neural connections to shut him back down.<ref>{{cite episode |title=Grimlock's New Brain |series=The Transformers}}</ref>

Although Unicron himself does not appear again, his origin in the animated series is later revealed. Unicron was created near the beginning of the universe by the diminutive genius known as Primacron, who intended for him to devour all life in the universe, leaving a blank slate that Primacron could use as he saw fit. However, Unicron turned upon Primacron, deciding that ''he'' would rule the universe and subsequently set out to achieve that goal.<ref>{{cite episode |title=Call of the Primitives |series=The Transformers}}</ref>
