Powers and Abilities Edit
Steel: Tetsutetsu's Quirk allows him to turn his body into steel, which gives him a great defensive ability as well as resistance to extreme temperatures such as heat and cold. He can also use it offensively to increase the strength of his unarmed attacks. Upon losing an arm wrestling match he mentions that he should have had more iron that morning, possibly implying that his quirk strength is fueled and affected by his diet containing iron.
