Golden Age: Luthor was the arch-enemy of Superman from 1940 to the mid 1950s. His first name was never revealed. Pre-Crisis Earth-One: Alexis "Lex" Luthor has a younger sister named Lena Thorul, and a niece named Nasthalthia "Nasty" Luthor (the daughter of an unnamed older sibling). Lex married Ardora of the planet Lexor, and together they had a son, Lex Luthor Jr., however both wife and son were killed in one of Lex's acts of revenge against Superman. Pre-Crisis Earth-Two: Alexei "Lex" Luthor was a diabolical genius who often battled Superman. He was killed by Brainiac during the Crisis on Infinite Earths. Pre-Crisis Earth-Three: Alexander Luthor Sr. was the husband of Lois Lane and father of Alexander Luthor Jr. He and Lois died when a wave of antimatter destroyed his universe. Post-Crisis New Earth: Alexander "Lex" Luthor was born and raised in the poverty-stricken "Suicide Slums" by abusive parents. As a child he was equally ambitious, charismatic, vengeful, and manipulative as he is in his adulthood. When he was a teenager, Lex, contracted the mechanic his parents used to rig their car for an explosion, so he could profit from the large insurance policy he took out in their names. With this windfall he began his company, LexCorp. Lex grew this business into the dominant corporate force in Metropolis and he often leverages his power as its owner in his favor. Lex Luthor's nemesis is Superman, who came to town and has been an obstacle to Lex's plans ever since. Buying the only known piece of Kryptonite on Earth, Lex wore it in a signet ring to keep Superman at bay for a long time, but it eventually gave him cancer and he had to have his hand amputated and replaced with a prosthetic. He managed to develop a way to combat the side effects of using Kryptonite so he could employ it to fight Superman. Lex was eventually elected to the Presidency of the United States, but he was later impeached. After his impeachment, and with LexCorp operating under Talia Head as CEO, Luthor's business assets were sold to the Wayne Foundation. Having gone underground, Lex was impersonated by Alexander Luthor Jr. from Earth-Three who recruited a group of villains he called "The Society". Lex was outraged and took on the mantle of "Mockingbird", the mysterious leader of the Secret Six, so he could recruit a new team to combat The Society and defeat his imposter. Alexander Jr. was eventually de-powered and stopped by a team of super-heroes. Post-Crisis Earth-0: Following the Infinite Crisis, Lex Luthor tracked down Alexander Jr. and had Joker kill him. He used the body of the imposter to get cleared of the crimes of which he had been accused. New 52 Earth 0: New 52 Earth 3: Alexander Luthor was the hero known as Mazahs in this universe. He was killed by the Earth 0 Lex Luthor.
