On a distant arid planet orbiting a red star, Luthor challenges Superman to a fight since Kryptonians lose power when exposed to red sun radiation. Befriending the planet's inhabitants, Luthor aids them in rediscovering lost technology that restores the water supply and helps the society rebuild. As a result, Luthor becomes a hero in the eyes of the planet, whereas his enemy Superman is detested as a villain. The people rename the planet Lexor and it becomes a regular home base and retreat for Luthor in-between his efforts to fight Superman and take over Earth. He later meets a local woman named Ardora (first called "Tharla" but renamed "Ardora" in later stories as well as the reprint of her first appearance). The two eventually fall in love and marry.
