Big Iron

Big Iron cuts a tall, muscular figure with cropped black hair and heavy eyebrows that curl upward and inward at their tips. Like the rest of his crew he sports a biker vest over a white undershirt, jeans, and a belt with an oversized buckle, and he arms both hands with iron gauntlets.

Loud, aggressive, and seemingly stuck in a permanent bad mood, Big Iron has almost no patience and reaches for violence at the first opportunity. He writes off outsiders as weak and routinely underestimates them, all while brimming with faith in his own might and that of his gang. That overconfidence runs so deep that he squares up against Tatsumaki even after learning she is the S-Class Rank 2 hero.

Big Iron and his gang take Erika hostage, and when the hero Feather tries to free her he cuts down several members before being beaten to the ground. Just as Big Iron moves to finish the hero, Tatsumaki flings Saitama through the wall and knocks Feather out. The Iron Fist members recognize the S-Class Rank 2 hero standing before them, but rather than back off, Big Iron sees a shot at glory and orders his crew to swarm her, striking at Saitama to clear him aside first. Saitama answers with one punch that blasts Big Iron up through the ceiling. He fights hand to hand, leaning on his iron gauntlets, and as an A-Class criminal is presumed to hold real strength, though little of it is ever shown.
