From the back of the book: "Costumed crusaders fighting against the forces of evil...monstrous villains terrorizing the world...your creations are limited only by your imagination! Duplicate your favorite comic-book hero, or design almost any super ability you can think of! Become a Blaster, hurling bolts of fire or lasers; a Ninja, blindingly fast and trained in the dark combat arts; or a Tank, strong enough to go toe-to-toe with a battleship. Anything you can imagine, you can be!"
