Superboy's nemesis, Lex Luthor, was introduced in "The Jewel of Techechal" (the first episode broadcast) as Clark's classmate at Shuster University. This version of Luthor was more interested in fixing basketball games and humiliating Superboy than anything else. But the season one finale, "Luthor Unleashed", completely changed his character. This episode adapted Lex Luthor's silver age comic book origin, in which Superboy rescues Lex from a lab accident that causes him to lose all of his hair, becoming the familiar bald villain Superman fans have come to recognize. Luthor blames Superboy for his hair loss and gains a new, more intense hatred for the Boy of Steel. From this point on in the series, Luthor is determined to destroy Superboy, rather than just humiliate him.
