REIGN OF THE SUPERMEN!
The third act in the Death and Return of Superman saga. Beginning in the final pages Adventures of Superman #500 (June, 1993) under the teaser "first sighting," four men appear bearing the Superman emblem. Actually, three men and one boy appear.
Each creative team on the four Superman titles had their own ideas on how Superman could return. The editorial decision at the time was to use all four ideas, with four very different Supermen appearing in Metropolis.
