The Omega Men are a team of extraterrestrial superheroes who have appeared in various comic book series published by DC Comics. They first appeared in Green Lantern #141 (June 1981), and were created by Marv Wolfman and Joe Staton.
After appearances in Green Lantern, Action Comics and The New Teen Titans, the Omega Men were featured in their own comics series which ran for 38 issues from April 1983 to May 1986. During its run, writer Roger Slifer and artist Keith Giffen created the mercenary anti-hero Lobo.
The Omega Men were assembled as a group of renegades and representatives of conquered Vegan worlds to fight Citadelian aggression. Pre-Infinite Crisis the team was based on the planet Kuraq. The Omega Men are important peacekeepers in their sector because the Green Lantern Corps is not allowed into Vegan space, due to a long standing agreement with the Psions.
