Alexander "Lex" Joseph Luthor () is a supervillain appearing in American comic books published by DC Comics. Created by writer Jerry Siegel and artist Joe Shuster, the character first appeared in Action Comics #23 (published on February 22, 1940, with a cover date of April that same year). He has since endured as the archenemy of Superman. While Superman represents hope and selflessness, Luthor personifies unchecked ambition and the supremacy of human intellect over the superhuman. Unlike many supervillains, Luthor is an ordinary human with no superpowers or secret identity.
