Lex Luthor is a comic book super villain in the DC Comics universe, and is mainly arch-nemesis to Superman. In the books he has been commonly conceived as either a mad scientist or a billionaire tyrant, bent on world domination. Either way, his characterization is that of a brilliant Machiavellian strategist, who always deduces the weakness of his enemies and uses it against them. He has been the leader of the Legion of Doom as well as the President of the United States under various artists' interpretations. He also appears in the Non-Disney vs. DC Villains War, as a major competitor.
