Official character text from packaging... 
Trusting but dumb, CRUMPLEZONE is often drawn into serving as the muscle to back up the paranoid plotting of his partner RANSACK. Huge, powerful and superfast, CRUMPLEZONE is sometimes surprised by sudden turns. Not that it matters—he’s the biggest guy on the SPEED PLANET, and crashing straight ahead through whatever gets in his way is his specialty. Twin-turbine ramjets can propel him at nearly the speed of sound, and selective thrust reversal allows him to fire hypersonic, high-explosive slugs nearly 12 miles.

UNLOCK THE POWER! The race to save CYBERTRON is speeding up! Change awesome three-wheeler from futuristic barrier-buster to evil DECEPTICON warrior and back again! He features cool electronic sounds and “high-explosive shell” launchers that really fire! When it’s time for a speedy getaway, convert back to vehicle mode and use the CYBER PLANET KEY to flip the thrusters forward!

Crumplezone is a massive Transformer. He loves to blast things, loves to crush things and LOVES to race as fast as he can all day long and all night long. But what he really loves is hanging out and causing all sorts of trouble with his best buddy Ransack! From putting grease on Overrides wheels, to Giving Clocker an atomic Speed Planet wedgie, Crumplezone is a punk that LOVES to cause trouble wherever he goes!

Speed Planet: The pure racing culture of the Speed Planet is about to change forever, as it becomes the first battleground in the war for the lost Planet Keys, ancient artifacts missing for eons on the lost colonies.  In order to save Cybertron Optimus Prime sends Hot Shot and Red Alert to face the untold dangers of this lost planet and an army of Decepticons, who seek the planet keys for their own evil ends.  

The speed planet is a tangled mass of roads, trails and aerial race tracks, ruled by the dazzlingly fast Override.  For millions of years, the inhabitants of the Speed Planet have been devoted to the pursuit of perfect acceleration, tuning their vehicle forms for optimum horsepower, displacement and torque.  It is a turbo-charged world of cold air intakes, narrowed air flow profiles and stiff struts, where only the fastest survive, and the slow are left behind, grills choked with the dust of a thousand street battles.
