Lex Luthor is one of the most dangerously intelligent men on the planet- a super-villain, a brilliant scientist, a billionaire industrialist, and Superman's greatest enemy. This combination makes him an extremely powerful and formidable opponent; he is ruthless, efficient and creative. In addition to his personal vendetta against the man who thwarts his every scheme, he despises the alien Man of Steel from an ideological standpoint for contradicting his human achievements. He has always been a controversial figure in the public eye due to LexCorp's corrupt business dealings, but he has also maintained political popularity. He has been a member of the Injustice Gang, the Injustice League, the Secret Six, the Secret Society of Super-Villains and Project 7734. Lex Luthor was created by Jerry Siegel and Joe Shuster and has had a lengthy publication history.
