learned that Damage was actually the son of the Atom, Al Pratt, and his wife. Iron Munro continues to serve as an adventurer and apparently benefits from extended youth. During the massive war between Imperiex and Brainiac 13, the Justice Society's Sand recruited an army of All-Stars, which Arn joined. Afterwards, he joined the Human Bomb and Damage in the Freedom Fighters. This group was doomed and Arn lost his good friend Roy when several of the F.F. were slaughtered by the Society. Recently, Sandra Knight also learned the fate of the child she gave up for adoption, Walter Pratt. Pratt became a homicidal maniac. His daughter, Katherine Spencer has now become Los Angeles' Manhunter. Pratt died when he was cut in half midstream in teleportation. Sandra met Kate Spencer, and months later brought Arn to Kate for an introduction to her and Ramsey, his great grandson. Iron Munro became part of a network called Supermen of America after Superman learned that he cannot be everywhere at once. Along with other heroes, like Steel, Super-Chief, Supergirl and Superboy, he has a signal watch that can be used for summons in emergencies. Iron Munro also works closely with the rehabilitated super-being Livewire and S.T.A.R. Labs employee Serling Roquette. Livewire also is accepted into the team. Powers Munro is endowed with superhuman strength and speed, is invulnerable to the point where small firearms will only bruise him, can leap almost an eighth of a mile, has enhanced reflexes, and ages at a slower rate than an ordinary human, hence why despite being in his nineties, he still looks to be in his thirties.
