The Supermen of the Multiverse are an army of alternate versions of Superman from different earths from the Multiverse. They were reunited for the first time in Final Crisis for different moments: first, assembled by Monitor Zillo Valla and later, gathered together by the Captain Marvel of Earth-5 and the Question from earth 0. Using the Ultima Thule as vehicle, their common objetive was fight against Mandrakk the Dark Monitor. They will reunite again to fight against the being know as Prophecy
The team choosed by Zillo Valla included Captain Marvel (from earth-5), Superman (native of earth-0), Captain Atom of Earth-4 Overman of earth-10 and Ultraman, under the promise to give each one a searched teasure. The Supermen land in Limbo, where Ultraman betrays them and joins with Mandrakk. After Ultraman's defeat, Superman tells Billy to go and gather Supermen, leading to the official formation of the Supermen of the Multiverse.
The team reunited by Captain Marvel arrived just in time to overcome Mandrakk and his ally, the vampirized Ultraman with their solar-based heat vision so that the Green Lantern Corps can stake them. The Supermen also help bring Earth back to its proper place from where Darkseid had drawn it.
The team of Supermen would be reunited again when the being know as Prophecy started to abduct the Supermen from several parallels earths. When the Superman of earth 30 crashed on earth 0, he encountered the native Superman, who was still recovering from the recent events of rebirth and was considering an anomaly, they were ambushed by the gatherers of Prophecy. They were helped by Justice Incarnate and by President Superman. After being defeated by Justice Incarnate, the gatherers went after Kenan Kong, the Super-Man from China and captured him. The SUpermen and Justice Incarnate then recruited the still free Supermen to fight back against Prophecy and rescue the prisioner Supermen. However Superman of earth 0choose to go to fight alone against Prophecy because he didn't want anyone else to risk their lives. But his effort was useless and he was defeated by Prophecy, who deemed him as an anomaly and was put whith the others Supermen who had their powers stolen.
However, Superman had used the Ultima Thule to sertve as a beacon so President Superman and Justice Incarnate could track him. The presence of the others Supermen reactivate the powers of all the prisioners Supermen and together they defeated Prophecy, who vanished surrounded by a blue halo, still claiming than he was the only who could spare the multiverse from oblivion.
