A space freighter has crash-landed on Earth, bearing a particularly lethal cargo ... and that's just the beginning of the trouble! By cargo, we don't mean the mysterious package that the Decepticons' fuel auditor, Ratbat has sent to Earth for reason unkown. Although that in itself is yet another ingedient in the growing recipe for distaster that's cooking on Earth. Ratbat wants his cargo back, and he's willing to send the Decepticon Triple-changers - Blitzwing, Octane and Astrotrain - to Earth to find it. But like we said, this is only part of the problem. It's the much smaller, but potentially far deadlier cargo that's going to cause trouble for Autobot and Decepticon alike. They're called Scrpalets - and you've never seen anything like them before! Believe it or not, they eat robots! And, as if all this wasn't enough, into this mess walk Blaster and Goldbug - our pair of roving Autobots! Plus, the return of the Autobots' human friend, G.B. Blackrock!
