Chaos
Blast-Off discovers a wimpy alien using a very powerful cannon: a bazooka-device which shoots green explosive crystals. The crystals are "shed" from the body of Chaos, a giant humanoid monster that Kup met ages ago. Galvatron goes to Chaos's planet and builds a giant gun (with which he plans to destroy Cybertron). Kup and some other Autobots stop him, and Kup turns the gun on his old enemy Chaos.
