What Is Lex Luthor’s IQ?

Lex Luthor has an IQ of 225, which is quite a bit higher than the average person, and higher than Superman of course. He uses his superhuman intelligence to build armor and weapons for himself with the main goal of killing the Man of Steel, but they also help him fight against Wonder Woman and Batman. Superman takes the adoration of the public away from Luthor and the villain wants nothing more than to kill him.

Lex Luthor is considered the smartest human in the DC Universe: some of his inventions include armor to rival Iron Man, steroids made from venom mixed with liquid Kryptonite to give him super strength, the Amazo Virus that strips heroes of their powers, and the Superman clone Bizarro – who ended up becoming more of a good guy than Lex ever would’ve predicted – but fought Superman brilliantly.
