Alexander "Lex" Luthor Jr. is a fictional character owned by DC Comics.

Created by Marv Wolfman and George Pérez, Luthor Jr. has a prominent role in the DC Universe storylines Crisis on Infinite Earths and Infinite Crisis.

Alexander Luthor Jr. is born on Earth-Three, the son of that world's Lex Luthor (known as Alexander Luthor) and Lois Lane-Luthor. Luthor Sr. is Earth-Three's only hero, fighting the Crime Syndicate (an evil version of the Justice League of America). In the 1985 DC Comics 12-issue limited series Crisis on Infinite Earths, a being known as the Anti-Monitor destroys innumerable universes (including Earth-Three) with an anti-matter wave. To save their son, the Luthors place him in an experimental device which carries the infant to the relative safety of Earth-One.

Alexander materializes on the abandoned satellite which was formerly headquarters of the Justice League. Harbinger takes him in, at the request of the Monitor. His passage through the anti-matter storm grants him power over both matter and anti-matter, dramatically accelerating his aging process. By the end of Crisis Luthor is a young adult, despite the passage of only a few weeks. After the Monitor's death, Alexander helps lead the heroes and villains of the DC Universe against the Anti-Monitor.

After defeating the Anti-Monitor (with the help of Kal-L, the Earth-Two Superman and the Earth-Prime Superboy), Alexander reveals that he has saved Kal-L's wife, the Earth-Two Lois Lane, from being erased from existence when the multiverse was destroyed. The foursome, no longer having a place in the Post-Crisis universe, retreat to a "paradise dimension" (which Alexander accesses with the last of his dimensional powers).
