Cast Iron, real name Milos Stojakovic, is a Global Defense Agency hero who can convert his whole body into solid steel. He first appears during the Invincible War, bracing to defend Russia against the rampaging variant Prisonincible.
When he armors up, his skin takes on a gray metallic cast. His costume pairs beige across the chest with red running down the arms and legs, and a pair of crossed hammers marks the belt, lending him a rugged, working-class air.
Almost nothing is documented about his life before the cape, only that he took up heroics and signed on with the G.D.A. On the opening day of the Invincible War he stands ready to meet Prisonincible as the variant tears into Russia.
The country is left in ruins, suggesting the fight went badly for him, yet he pulls through and is later seen among the mourners at Rex Splode's funeral.
