The Ultra-Humanite's plan continues with the capture by the Secret Society of Super Villains of the heroes of Earth-One - Batman, The Atom and Firestorm, as well as those of Earth-Two - Hourman, Flash, Johnny Thunder and his Thunderbolt, and Superman who is defeated by the Ultra-Humanite himself. Transporting the heroes to his palace in Nepal on Earth-Two, The Ultra-Humanite begins the process that will banish them to limbo and apparently rid either Earth-One or Earth-Two of all other heroes.
