The character Unicron first appears in the opening scene of 1986's "", 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 to Galvatron. He then uses the battered bodies of the other Decepticons and creates Scourge, the "tracker", from Thundercracker and his "huntsmen", the Sweeps, from Kickback and Shrapnel. Cyclonus, the "warrior" is then created, from either Bombshell or Skywarp (an animation error makes it unclear). 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.
