Inspired by Superman's selflessness, John Henry Irons used his engineering genius to reinvent himself into a champion in his own right. 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.
