The Ultimate Vampire Resource and Directory

L.E.G.I.O.N., is a team of fictional extraterrestrial superheroes, a science fiction comic book published by DC Comics. They first appeared in Invasion! #1
(December 1988), and were created by Keith Giffen, Bill Mantlo and Todd McFarlane. The original series chronicled the formation and activity of an interplanetary police force founded and led by Vril Dox whose mission was to act as a peace-keeping force in the galaxy much as the Omega Men and Green Lantern Corps had done before them. They are the 20th century forerunners of the Legion of Super-Heroes, and some of the 30th century Legionnaires are descendants of L.E.G.I.O.N. members.
