"Blurr and Wheelie are ambushed on their mission to take the transforming cog for Autobot City to Earth and are left hurtling helplessly toward a moon of Jupiter: Io. All hope lies with Marissa Faireborn of the Earth Defense Command, who even now rockets toward Io. Meanwhile, a daring raid led by Rodimus Prime and the Aerialbots freed Ultra Magnus, Kup, and Spike an instant before the planet was detonated by the deadly Quintessons. Buffeted by the terrific force of Quintessa's explosion, Rodimus Prime and his companions tumbled out of control and landed on Goo, the stickiest planet in the universe. Springer had just been vacuumed up and destroyed by the elemental processing unit of Goo, when suddenly, the Decepticons attacked!"
