On the run, Speeda Demon realizes that the only way to keep Hero Factory from getting him is to get them first. From every corner of the galaxy, he assembles an army of criminals. Their mission: wipe Hero Factory right off the map. Outnumbered and outpowered, the heroes Furno, Nex, Stringer, Bulk, Breez, and Stormer XL must come up with a way to win--or else see the galaxy become an empire of crime.
