Lex Luthor, Jr. is the name of several characters from the DC Universe.
The most notable of them is Alex Luthor; the son of Lex Luthor and Lois Lane from Earth-Three. After his universe was destroyed by the Anti-Monitor during the Crisis on Infinite Earths, Alex became a hero to defeat this cosmic entity, but he became embittered by the failures of the other heroes, intent on restoring the original Multiverse at any cost. After escaping from his doomed world, Alex was given power over matter and anti-matter, which he can use to create bursts of energy and control dimensional portals. He created the Secret Society of Super-Villains and later became a member of the Black Lantern Corps after being killed by the Joker.
Lex Luthor, Jr. was created by Marv Wolfman and George Pérez, first appearing in Crisis on Infinite Earths #1 (1985).
