Lex Luthor

He’s the most intelligent man on Earth. But Lex Luthor has only ever used his brilliant mind for selfish gain and to further his own bitter vendetta against those he feels have done him wrong. A notorious sociopath and xenophobe in almost every one of his incarnations—be it scientist, businessman or even the President of the United States—Luthor always uses his power and influence not to help mankind, but to attempt to destroy the one man on the planet who makes him feel insignificant: Superman.
