Challenge of the GoBots

The GoBots are forced into a grudging alliance to defeat a race of enormous, metal-eating spiders.

Cy-Kill has Braxis create a weapon that can induce stars to go nova, roasting all their planets, and the Guardians must stop him before he can use it on the Sun.

Cy-Kil reduces Leader-1, Scooter and Turbo to the size of toys, but when the tiny Guardians escape their enemies must shrink themselves to go in pursuit.

The Renegades try to take over GoBotron by replacing the Guardian leaders with robotic ringers.

Warlike insects invade the Earth thanks to Cy-Kill's space rift, but his plan backfires when the bugs prove too difficult to eradicate even for the Renegades.

The Guardians must defeat the invading aliens as well as the Renegades.

Nick, Matt and AJ are kidnapped at the heart of Gobotron, but when they escape the Renegades they fall into the hands of Wrecks, the leader of a gang of thieves, who enters Matt in a bizarre form of gladiatorial combat.

The Guardians try to help a planet whose elfin inhabitants have been conquered by the Renegades, who have stolen the elves' amazingly powerful Tramulet.

The Guardians launch an all-out effort to find and destroy Rogue-Star.

Dr. Frost and his nephew invent a device that can alter the Earth's weather, and Cy-Kill snatches it to plunge the Earth into a permanent ice age.

When a giant robot designed to protect humanity from the Renegades turns against its creators, the Renegades are quick to take advantage of the situation.

The Trindles recover their Tramulet with the Guardians' help, and turn Cy-Kill's plans against him.

The Renegades hold a town's children hostage to force the adults to build a giant Ultra Zod, which will conquer Earth and then GoBotron.
