Synopsis:
The Justice League and the Silver Sorceress discover that the creator of Wackyworld, Mitch Wacky, is still alive. Mitch put himself into cryogenic sleep because he was suffering from a deadly disease. This allowed him to survive the holocaust which destroyed his world. Wacky uses his computers to learn that his robots constructs robot duplicates to populate the amusement park. They even created robot versions of the Extremists. The real ones died in the holocaust.

The Silver Sorceress brings Wacky and the Justice League back to Earth. Wacky's illness is treated. The Justice League then attacks the Extremists, who still threaten the Earth with a nuclear arsenal. Wacky uses a button to deactivate the robots. However, Dreamslayer is not a robot. He is the real villain who now tries to destroy Earth. The Silver Sorceress who was disguised as Crimson Fox during the fight stops him.
