The perfect combination of brains and brawn, John Henry Irons was one of four different people to take up the mantle of Superman when Kal-El lost his life while saving Metropolis from the monster known as Doomsday. Initially referred to by the media using Superman's nickname, "The Man of Steel," Irons simply went by Steel when Superman came back from the grave.

A former weapons engineer, John Henry Irons moved to Metropolis to start a new life. There, on one fateful day, Superman saved his life. Forever grateful, John Henry paid it forward when the city's protector died. He took up the fight to protect the innocent in Superman's name, wearing his iconic "S" shield in tribute.

Irons used his scientific genius to construct a suit of armor that allowed him to fly and gave him superior strength. He also created a giant metal hammer in homage to his namesake, the folk hero John Henry.

Now a permanent member of Superman's extended family, Steel is living proof that everyone has it in them to become a Superman.
