Lex Luthor is a fictional character, a supervillain who appears in comic books published by DC Comics, and the archenemy of Superman, although given his high status as a supervillain, he has also come into conflict with Batman and other superheroes in the DC Universe. Created by Jerry Siegel and Joe Shuster, he first appeared in Action Comics #23 (April 1940). Luthor is described as "a power-mad, evil scientist" of high intelligence and incredible technological prowess.[1] His goals typically center on killing Superman, usually as a stepping stone to world domination. Though he periodically wears a powered exoskeleton, Luthor has traditionally lacked superpowers or a dual identity.[2]
