Lex Luthor

Lex Luthor's History
While Superman has gone toe-to-toe with heavily-armed robots, despotic aliens, and even gods in the past, his most constant enemy is a mere human: Lex Luthor. The two have a long history together, dating back to Clark Kent's childhood friendship with Luthor in Smallville, Kansas. A child prodigy, Luthor grew up to be a respected scientist and corporate head in Metropolis, running the multi-billion-dollar company, LexCorp. However, when Superman first appeared in Metropolis, Luthor grew jealous, and eventually hateful upon learning of the hero's alien origins. Believing humanity shouldn't rely on an alien being to solve their problems, Luthor declared war on Superman.

While constantly scheming ways to kill Superman and establish control over the human race, Lex Luthor usually remains respectable in the eyes of the public. Recently, Luthor ran for President of the United States, and succeeded. When Superman and Batman began to expose Luthor's criminal acts, he went insane with rage and attempted to kill both heroes. He failed, and was deposed. However, he later convinced the public that an alternate universe version of himself had been the criminal, and regained their trust.
