Aliens capture Lex Luther, do something alien on his brain, and turn him into a civilized, nice guy. And he falls in love with Lois Lane, who initially rebuffs him as she's still pining for Superman. One day, her car stalls and she gets tired of waiting for Superman to rescue her, so she jumps off a cliff, incurring a severe brain injury. Lex Luther has just invented a device that will save her from death. When Lois wakes, she discovers LL saved her life, not Superman. She immediately marries LL and they start a family. They have a son who grows up to be a Juvenile Delinquent. And of course, the kid wasn't told about LL pre-alien change. He breaks into a locked room and sees all the mayhem his father caused, esp. against Superman. And the kid is so impressed that he wants to continue his father's legacy by attacking Superman.
