Earth-0

Earth-0 was an alternate Earth from the pre-Crisis multiverse that resembled the Bizarro World. It was destroyed in the Crisis.

Post-Zero Hour

Earth-0 was recreated by Alexander Luthor during his efforts to create a perfect Earth from resurrected components of the pre-Crisis multiverse. It ceased to exist when his equipment was destroyed by Superboy.
