Facing defeat on Gobotron, renegade GoBots Cy-Kill and his cronies Crasher and Cop-Tur, steal an experimental GoBot weapon called Astro-Beam and fly off to Earth to regroup and try conquer that planet first instead.
The Guardians contend with the monster Zod when the Renegades attack the Arctic island of Stolbovoy to obtain the energy source sorium.
Cy-Kill attacks the US military and uses the sorium to power a device that seizes control of the minds of every human on Earth.
With the world against them and Leader-1 captured by the Renegades, Turbo and Scooter go on the run.
The reunited Guardians must break Cy-Kill's hold over Earth in order to save GoBotron from a mass-produced fleet of Zods.
In a freak accident Scooter's holo projetion unit is damaged in battle.
This animated adventure follows the shape-shifting GoBots as they are recruited by Solitaire, a robot that can transform into a rock, to help out with a power struggle among her kind. Leaving their home planet, Gobotron, the heroic GoBots travel to Solitaire's world to fight Magmar, the ruthless Rock Lord, and his minions. The GoBots must also battle the scheming Renegades, who decide to ally themselves with Magmar, making the GoBots' quest to vanquish evil that much more difficult.
