In almost every major Superman live-action adaptation, Lex Luthor is never far behind, being one of the Man of Steel's greatest villains for over 80 years. Wherever Krypton's Last Son appears, his extensive rogue's gallery follows him around. From major antagonists like Lex, Brainiac, Doomsday, Metallo, Parasite, and General Zod, Kal-El's mythology has some very dynamic and powerful foes he goes up against regularly. Even though Superman has to battle some incredibly dangerous threats, his biggest one may actually be the one without any superpowers, and that is Lex Luthor. As seen in the comics, Superman/Justice League cartoons, and every live-action Lex Luthor, the villain needs only his intelligence and sheer willpower to remain Superman's archenemy, posing a threat that Clark can't simply just punch his way through.
