A band of supervillains (composed of Metallo, Kalibak, Livewire, Weather Wizard, and Toyman) team up to get revenge on Superman. While saving Batman and Wonder Woman Superman sacrifices himself and is seemingly vaporized. The League defends Metropolis without him, except Batman, who seeks the truth. In 30,000 Years in Future, Superman wakes up, but the sun has turned red, removing his superpowers. He encounters a humbled Vandal Savage, the only human left alive after an attempt at world domination staged a few months after Superman's disappearance.
