Growing up, John Henry Irons was always inspired by heroes, and after his parents' death he realized they named him after John Henry because they wanted him to be hero like the John Henry of legend.[1]

After progressing through graduate school, Doctor Irons was hired by General Sam Lane to create a weapon capable of protecting the Earth from an alien invasion. After Lex Luthor joined the operation Doctor Irons kept the prototype war suit called Metal-Zero hidden for himself, while working with Luthor on a new Metal-Zero suit. When Luthor managed to capture Superman Doctor Irons turned in his resignation upon witnessing the torture the unfortunate hero was under going.[2]

Shortly afterwards during the Terminaut invasion of Earth led by Brainiac Doctor Irons put on the original Metal-Zero armor to help protect the city. Surveying the attack Steel noticed Superman in pitched combat with the newly armored John Corben and intervened with the intent to destroy the new Metal-Zero armor. After winning a short battle against Metallo, Steel helped Superman determine the speed he'd need to reach in order to propel himself into space to save New Troy from Brainiac.[3]

While Superman took the battle to space, Steel remained on Earth to help manage the destruction caused by the abduction of the New Troy district of Metropolis.[4]

After this he and Superman partnered up several more times to fight crime and a menace known as the Kryptonite Man, Steel managed to aid Superman in the villain's defeat and even found a way to deactivate the villain's powers.

After facing the villain Doomsday alongside Superman he was infected with a strange otherworldly toxin, in a bid to prevent further such infections he coated his skin in a malleable liquid steel film, which would protect him from otherworldly infections but did limit his emotional responses.


  • Organic Steel Coating: Steel is covered in an organic steel that prevents otherworldly infections.[5] The steel can be used to limit heart rate, effectively limiting emotional responses.[6]
  • Power Distribution: On touch, Steel can coat others in this substance, with its effects transferred to them as well.[7]

John Henry is dating Superwoman (Lana Lang).
