L.E.G.I.O.N. is the Licensed Extra-Governmental Interstellar Operatives Network, an inter-galactic police force that is hired by different planets. Their founder and leader is Brainiac 2, who runs the organization out of their headquarters on planet Cairn. There is also a related team called R.E.B.E.L.S., who were formed to oppose L.E.G.I.O.N. when it was taken over by the evil Brainiac 3. Their descendants in the 30th Century became the Legion of Super-Heroes. L.E.G.I.O.N. was created by Keith Giffen, Bill Mantlo, and Todd McFarlane, first appearing in Invasion! #1. (1988)
