Challenge of the GoBots (also known as simply Gobots) is an American animated series produced by Hanna-Barbera Productions, based on the GoBots toy line released by Tonka. Most of the toys were imported from the Japanese Machine Robo toy line.

The GoBots originally debuted in animated form as a five-part miniseries, which aired in syndication from 29 October to 2 November 1984. A regular series followed the next year, premiering 16 September 1985. The series was later rerun on the USA Cartoon Express.


Thousands of years ago on the planet GoBotron, there lived a race of human-like beings known as Gobots. 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 GoBings brains into large robot bodies known as "GoBots". The GoBot forms 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.

Comparisons to Transformers

The franchises of GoBots and Hasbro's Transformers have often been compared due to the obvious similarities between the products. Although GoBots were technically first to reach the market, Transformers became the clear leader in both the marketplace and in popular culture.

Examples of the similarities between the brands' backstory include:

  • Both are opposing forces of robots engaged in civil war which transform between robot and vehicle-based forms which represent good and evil respectively.
  • GoBots hail from Gobotron where Transformers hail from Cybertron
  • Both franchises introduced female robot characters. However, GoBots featured these characters in the premiere and maintained the character(s) as regular players. Transformers did not introduce female robots until the second season and used them only sparingly before the movie.
  • Both TV series featured veteran voice-actors Frank Welker and Peter Cullen,the leaders of the Decepticons and Autobots respectively.
  • While most likely coincidental, the Last Engineer is similar in concept to the Transformer 'god', Primus, whose consciousness also dwelled deep within their homeworld.

DVD Release

Warner Archive has released the entire Challenge of the GoBots TV series on DVD. There are no DVD plans for the movie, GoBots: Battle of the Rock Lords.
