The Phantom Zone

It is the shadowy realm discovered by Superman's father, Jor-El, into which the doomed planet Krypton consigned the worst of her criminals. Yet long after the destruction of Krypton, the Phantom Zone has persisted - and now General Zod, Faora, and the Zone's other Kryptonian convicts have found a way to escape their twilight prison and wreak deadly havoc on Earth, with Superman powerless to stop them!
