 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 GoBeings 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.
