In 1992, heroes from Centaur Publications (a Golden Age publisher whose properties fell into the public domain) were revived in the form of the Protectors (Airman, Amazing-Man, Aura, Arc, Arrow, Ferret, Man of War and Mighty Man, among others). Several of these characters had short-lived spin-off titles of their own. The Centaur heroes and other characters from Adventure (Miss Fury and Rocket Ranger), Aircel (Cat & Mouse and Men In Black) and Eternity (Dinosaurs For Hire, Ex-Mutants and Shuriken) plus Dead Clown and Widowmaker were put together in one Universe to form the Genesis line.
