Alexander Luthor, Jr.

Alexander Luthor, Jr. is a fictional supervillain from DC and a major player in the Crisis storyarc.

Alexander Luthor, Jr. was born on Earth-Three, the son of that world's Lex Luthor and Lois Lane. The senior Alexander Luthor is Earth-Three's only hero, fighting the Crime Syndicate, an evil version of the Justice League of America. During the Crisis on Infinite Earths, the being known as the Anti-Monitor destroys innumerable universes, including Earth-Three, with an anti-matter wave. To save their son, the Luthor’s place him in an experimental device that carries the infant to the relative safety of Earth-One. Alexander materializes on the abandoned Justice League of America's Satellite. 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, although the exposure also dramatically accelerates his aging process. By the conclusion of the Crisis, Luthor is a young adult, despite the passage of only a few weeks. After the Monitor's death, Alexander helps lead both heroes and villains against the Anti-Monitor. After defeating the Anti-Monitor with the help of Earth-Two Superman, and Earth-Prime Superboy, Alexander reveals that he has saved Earth-Two Superman '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 new Post-Crisis universe, retreat to a "paradise dimension" Alexander accesses using the last of his dimensional powers. The four survivors spend years in the dimension after the crisis. Alexander, who has rapidly aged to his mid-30s, grows frustrated, and becomes colder and detached from the well-being of the universe's living beings. Superboy-Prime also becomes frustrated as well, and Alexander uses this opportunity to convince him to help fix reality.
