In the 31st century, as the fight in Justice League headquarters continues, Earth-Man pushes a powerless Superman toward Earth, protected only by his flight ring. Superman's Legion colleagues free Chameleon Girl, and unhook Sun Boy from the machine. But the sun won't change until Sun Boy is awakened, which falls to Chameleon Girl. Earth-Man has destroyed Superman's flight ring in low Earth orbit, pushing him to plunge into the sidewalk in front of the old Legion headquarters. But as he approaches, the sun turns back to yellow, and he gets his powers back. He frees some aliens that were just rounded up, and scolds an officer for imprisoning them. But Earth-Man arrives, and uses the stolen Legionnaires powers to fight Superman. But the rest of the Legion arrives, and join the battle. Superman delivers the final blow, knocking out Earth-Man. He and the Legion then confront the invasion force, and convince them to stand down. As the Legion gets ready to return Superman to his time, he reminisces about the first time they did so, and he remembers not feeling so alone anymore.
