Iron Munro

Iron Munro (Arn Munro) is a superhero character appearing in American comic books published by DC Comics. Roy Thomas created the character in 1987 for Young All-Stars. He largely served to replace Superman in stories set during World War II after the Crisis on Infinite Earths storyline eliminated continuities in which Superman was active in this period.

Following the cancellation of Thomas' World War II-set comic All-Star Squadron, a follow-up series was created following a new team, the Young All-Stars. Iron Munro was one of several new characters Thomas created as analogues for popular superheroes written out of the continuity, with comparable powers and appearance to Superman's. He was inspired by two 1930s pulp fiction characters who in turn prefigured Superman: John W. Campbell's science fiction hero Aarn Munro, who appeared in comics as "Iron Munro", and Hugo Danner, the protagonist of Philip Wylie's 1930 novel Gladiator, who had powers similar to Superman's and is sometimes seen as an inspiration.

Young All-Stars did not achieve the popularity of All-Star Squadron, which had featured better known characters from the Golden Age of Comic Books, and the series was cancelled in 1989 due to low sales. Iron Munro continued to make occasional appearances in DC Comics.
