Back cover

A sabotaged experiment threatens to destroy all of Hero Factory. Stormer, Bulk, Furno, and Breez expect to give up their lives, but instead they wake up in another world--a world without Hero Factory. In this dark, mirror world, they find there are no Heroes, and any act of heroism is against the law. This terrifying new world is ruled by Von Nebula, Speeda Demon, and more villains than the Heroes can count. Worse still, this universe also has swarms of robot-controlling brains ... but these have a thirst for destruction. Now, it's up to a handful of Heroes and a world of villains to stop the brains before they destroy both worlds.
