Plot summary
A cosmic storm passes through the planet Earth, bringing with it a mysterious plague which kills nearly the entire male population (an event later referred to as the Fall).[2] The only two men who survive are Superman and his archenemy Lex Luthor. Superman was immune to the plague due to his Kryptonian DNA, and Luthor had sealed himself away from the storm's radiation in his battle armor.[1]
