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
Autobots, 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. 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, crashes a
Quintesson spacecraft through his eye. 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. Unicron was voiced by
Orson Welles. 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. 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's eyes (breaking one 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. Unicron's head is subsequently blown off into space by an explosion instigated by the Autobots. 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, and one of their number,
Strafe, severs enough of Unicron's neural connections to shut him back down. 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.
Unicron trilogy Unicron would appear in
Transformers Armada, voiced by Mark Acheson. In episode 23, several of the human allies discover Sideways within their computers, and attempt to stop him, but not before learning that his accomplice was Unicron within the mainframe acting as a failsafe. The final season depicts Unicron as the main antagonist. Called the
Unicron Battles, the Transformers Earth groups return to Cybertron. The humans learn Unicron had made the Minicons to take control of Cybertron, but the Minicons revolted and become part of the Transformers' own civil war. Unicron appears in the sequel series
Transformers: Energon, set 10 years after the Unicron Battles. The autobots successfully destroy Unicron, but Unicron manages to place his consciousness within Megatron. In the final episode, Megatron is corrupted by Unicron, leading to another confrontation with Optimus Supreme. Around this time, Primus, Unicron's sibling, creates an energon sun and attempts to trap Unicron's soul with it. Both he and Megatron are destroyed for good, and the energon sun recreates Alpha's planets that were destroyed long ago. ==Publication history==
