A cosmic storm passes through the planet Earth, bringing with it a mysterious plague which nearly kills the entire male population (an event later referred to as the Fall). The only two men who survive are Superman and his archenemy Lex Luthor... Superman and Lois Lane's son, Adam Kent, is the first newborn male since the storm hit, and more are born through Superman's DNA, granting them Kryptonian powers.
