 * The Justice League (Wonder Woman, The Flash, Cyborg, Green Arrow, Maxima, Vixen, and The Atom) learns that a copy of Project: Doomsday plans (thought to be destroyed in Wonder Woman: Amazons Attack) are in the hands of Professor Ivo (last appeared in Plastic Man).
 * They storm his lair, but are attacked by his creation, Amazo. Superman, Plastic Man and Aqualad arrive to assist the League. Amazo captures Superman, who was programmed to create a Superman clone by Ivo. The League captures Ivo and learn that Project: Doomsday was created to stop another Kryptonian from entering Earth, which satellites have detected. Amazo and a cloned Superman were to be created to stop it.
 * Shazam and Supergirl arrive to join the League in stopping Amazo, however the cloning process of Superman goes haywire, and forms Bizarro Superman.
