"Reign of the Supermen!" is a major story arc that ran through DC Comics' Superman titles in 1993, forming the third and final part of the landmark "The Death of Superman" crossover event. Written primarily by Dan Jurgens, Roger Stern, Louise Simonson, Jerry Ordway, and Karl Kesel, the arc picks up in the months following Superman's fatal battle with Doomsday. With Metropolis descending into chaos and the world mourning its greatest hero, four mysterious new figures emerge, each claiming to carry on the Superman legacy in their own way.
The four contenders include the cold and visor-wearing Last Son of Krypton, the technologically armored Man of Tomorrow (who is secretly the villainous Cyborg Superman), the brash teenage clone Superboy, and the steel-wielding John Henry Irons, known as Steel. The storyline explores themes of grief, legacy, and what it truly means to be Superman, as Lois Lane and the supporting cast investigate which of these new heroes—if any—is the genuine article.
The arc was a massive commercial success, continuing the sales surge that began with Superman's death. It introduced the character of Steel, who would go on to headline his own series and later be adapted into a feature film, and reimagined Superboy for a new generation. The entire "Death of Superman" saga remains one of the most famous and influential comic book events ever published, fundamentally reshaping how the industry approached crossover storytelling and character death.
