Later, it is revealed that the metal has grown out from where Nathan's amputated leg once was, forming metallic bone, muscles, and flesh. Waking in his hospital room, Nathan is shown to have superhuman strength. Dr. Mid-Nite informs Nathan that he is now a being of living steel, due to an unknown reaction to Reichsmark's blood. However, the steel tissues do not give Nathan tactile response, meaning he cannot feel textures or temperatures, nor gauge exerted pressures, and his weight has greatly increased, causing his footsteps to crack the ground. He is given a costume, a "second skin" of a stainless steel alloy developed by Dr. Mid-Nite and Mr. Terrific specifically to restrict his movements and reduce his strength to a more manageable level. They chose the costume's colors because of Heywood's heritage. He then joins the Justice Society to defeat the Fourth Reich. Afterwards, the press asks if he is the new Commander Steel. Nathan denies it, saying that he is just an ordinary citizen, so he is called "Citizen Steel" by Power Girl.
