Overview
Steel is a superhero appearing in comic books published by DC Comics. He is a genius engineer who built a mechanized suit of armor that mirrors Superman's powers, and initially sought to replace him after he was killed by Doomsday. After Superman was resurrected, he accepted Steel as an ally. His real name is John Henry Irons and he wields a sledgehammer—this is a reference to the mythical railroad worker John Henry. He has a niece named Natasha Irons who is also a superhero in a similar mechanized suit of armour.
The character was portrayed by Shaquille O'Neal in the 1997 film adaptation of the same name. Wolé Parks portrays the character in the television series Superman & Lois.
