Team Luthor was a privatized civilian security force developed by Lex Luthor. At the time of its formation, Luthor established this security force to replace Superman during a period when the Man of Steel was in self-imposed exile from the planet Earth. Although Luthor seemingly perished in an airplane crash shortly thereafter, Team Luthor continued to function. During the "Reign of the Supermen!", Luthor had Matrix use her feminine wiles to convince the neophyte clone hero Superboy to join Team Luthor as well.
