DiC cartoon Overkill made his first animated appearance in the
DiC-produced
G.I. Joe animated series, voiced by
Dale Wilson. Here he appeared to be fully robotic, and his appearance was that of his first action figure. His key episode in this series is "The Eliminator", in which he receives an upgrade via the Eliminator chip, which makes him stronger, faster and smarter. This puts him in Cobra Commander's good graces. DiC appearances include: • "The Eliminator"—Overkill gets an upgraded laser in his chest (Laser is included in his V1 action figure) and becomes 'The Eliminator'. • "The Sword"—where he's sent by Cobra Commander to retrieve the Sword of Destiny from
Night Creeper Leader (who, naturally enough, wants it for himself). • "El Dorado: The Lost City of Gold"—where he's possessed by the spirit of Commander Fernando Luiz Jorge Pizarro, cousin to the explorer
Francisco Pizarro. • "Kindergarten Commandos"—Overkill shows up to help Cobra Commander fight off the forces of six small children and the G.I. Joe
Mercer. His appearance in this episode is relatively minor. • "Keyboard Warriors"—Another minor appearance.
Valor vs. Venom Overkill returned in the CGI movie
G.I. Joe: Valor vs. Venom by
Reel FX, now clearly a half-human and half-machine cyborg version, with a variety of robotic appendages and a tendency to repeat the end of his sentences in a manic tone of voice. He serves Cobra as
Doctor Mindbender's lab assistant and BAT commander. Overkill looks down upon "organics", and believes he and his BATs are better candidates to rule the world. In a series of fortuitous circumstances, he makes an alliance with "Venomous Maximus", a mutated and brainwashed
General Hawk. Together, they attempted to remove
Cobra Commander from power, and control Cobra themselves. The Joes are able to turn Maximus back into Hawk, and the Cobra base begins to explode around Overkill, who IS seemingly crushed in the ensuing explosion. However, following the credits, Overkill's robotic hand rises up on the screen. This has been theorized as a preview of the abandoned
Robot Revolution line rumored to be following
Valor vs. Venom.
Sigma 6 Overkill returns in
G.I. Joe: Sigma 6, he is now inside a rejuvenation tank and wearing new armor, appearing far more robotic than when he last appeared. He is also revamped from a monotonous automaton lab assistant to Cobra's chief scientist. He is smarter and more devious, with a free will of his own. Overkill is still attempting to overthrow Cobra Commander with his new B.A.T.s, this time in secret, and has a new more powerful BAT called Overlord Vector, which he uses to kidnap General Hawk's son, Scott. Overkill believed Scott had hacked into Cobra's computers, and possessed a formula which would allow his B.A.T.s to evolve as they fought. His kidnapping of Scott ultimately led the Joes to Cobra's underwater headquarters. However, when Overkill scanned Scott's mind, he found that his discovery was just pure dumb luck. Overkill fled as
Snake Eyes battled his creation, Overlord Vector. Overkill managed to escape, and still resides in his tank inside his lab in the underground Cobra base, now planning to get hold of the power stones sought by the Joes and Cobra, to launch his Robot Revolution. With the foiling of Cobra's power stones plot, Overkill has apparently given up that quest. During the second season of the cartoon, Overkill is finally able to create himself a body, and is removed from his healing tank. ==Video game==
