Gobots title

Challenge of the GoBots (or simply GoBots) is an American animated series produced by Hanna-Barbera. It is based on the Gobots toy-line released from Tonka. The show was first broadcast 8 September 1984 in syndication, then the show joined the weekday/weekend programming block The Funtastic World of Hanna-Barbera on 15 September 1985. It was later rerun on the USA Cartoon Express.


GoBots dealt with two opposing forces of transforming robots from the planet Gobotron: the heroic Guardians and the evil Renegades. The Guardians were led by Leader-1 while the Renegades were led by Cy-Kill. The characters rarely had guns, instead shooting energy blasts out of their fists. The female robots on the series, such as Crasher, were built like the males, but with some distinguishing female features. The GoBots’ origin as GoBings accounted for the presence of genders among the robots.

The series generally focused on a small number of robots from each faction (Leader-1, Turbo, Small Foot, Sparky and Scooter vs. Cy-Kill, Fitor, Geeper-Creeper, Cop-Tur, Crasher and Tank) who were virtually ever-present with other characters seeming to rotate in “guest-star” roles. GoBots had no clear division between the two factions. The characters had no identifying insignias or markings to indicate their allegiance, although it was indicated on the toy packaging. Likewise, there was no commonality of design within each faction. The only “theme” to a side was that anything that turned into a “monstrous”-looking robot or vehicle was a Renegade.


Thousands of years ago on the planet Gobotron, there lived a race of human-like organic beings referred to as “GoBings.” Civil war erupted on the planet when the power-hungry terrorist group known as the Renegades arose, led by a madman dubbed the “Master Renegade,” who waged war against the peaceful Guardians.

When a Renegade sabotage operation inadvertently resulted in a gigantic asteroid colliding with Gobotron, the natural disasters that resulted from the asteroid’s impact pushed the GoBings to the verge of extinction. However, the genius who became known as the “Last Engineer” saved his people, taking his experiments to replace parts of his own body with mechanical substitutes to the ultimate extent and transferring the brains of the GoBings into large robots known as “GoBots.”

The GoBots possessed an additional ability; after being run through the device named the Modifier, the GoBots’ bodies were able to transform into other vehicles. His work done, the Last Engineer intended to retreat to a pre-prepared workshop elsewhere in the galaxy, but the Master Renegade stole his ship and escaped in his stead. The Last Engineer placed himself into suspended animation beneath the surface of Gobotron, while above, the war continued to rage between the Guardians and the Renegades, now all encased in GoBot shells.

In the last quarter of the 20th Century, the planet Earth became involved in the conflict between Leader-1’s Guardians and Cy-Kill’s Renegades. During one of these battles, one of Leader-1’s lieutenants, Turbo, became severely damaged. Unwilling to let his friend and teammate die, Leader-1 began his quest to find the legendary Last Engineer. Leader-1 found the person he believed to be the Last Engineer, but Leader-1 had unwittingly released the Master Renegade (though he did repair Turbo to gain the Guardians’ trust).

The Guardians later found the true Last Engineer, who was instrumental in frustrating the alliance between Cy-Kill’s Renegades and the Master Renegade. The Master Renegade later escaped the custody of the Renegades, and plagued both factions, notably attacking the UniCom colony of New Earth.
