Comics Street and Smith Aarn Murno was renamed as Iron Munro in
Shadow Comics #1 in 1940, published by
Street and Smith, the same publisher behind
Astounding Stories. In this version, set in the distant future of 2093 AD, a colonization expedition to
Ganymede becomes stranded after their ship is caught in Jupiter’s immense gravitational field. Unable to escape, the crew settles on the inhospitable moon. There, a child is born and raised under high-gravity, this child becomes Iron Munro, a space-born hero of immense strength and agility, who eventually makes his way to Earth to fight evil.
DC Comics In 1987, Roy Thomas reimagined the character for DC Comics as part of the
Young All-Stars, following the events of
Crisis on Infinite Earths. Now spelled
Arn Munro, he was reintroduced not as a space hero but as the son of
Hugo Danner, the protagonist of
Philip Wylie’s 1930 novel
Gladiator,a work widely regarded as a precursor to
Superman. In this post-Crisis continuity, Hugo Danner fakes his death after a life of isolation and pain caused by his superhuman abilities. He briefly returns to Colorado, where he fathers a child, Arn, with his former love Anna Blake. Raised in secret and aware of his powers, Arn promises to keep them hidden until adulthood. As a teenager, he earns the nickname “Iron ” while playing baseball and eventually joins the Young All-Stars during World War II as Iron Munro. == Trivia ==
