Big Iron

Big Iron (ビッグアイアン, Bigguaian) is an A-Class criminal. He is the leader of the Iron Fist gang.

Appearance
Big Iron is a tall, muscular man with short black hair and large eyebrows that curl up and inward at their tips. Similarly to the rest of his gang, he wears a biker vest, white undershirt, jeans, and a belt with a large buckle. He is also equipped with a pair of iron gauntlets.

Personality
Big Iron is bold, aggressive, ignorant, and seems to be perpetually aggravated. He has very little patience and will resort to violence quickly. He sees outsiders as weak and tends to downplay and underestimate them. Big Iron is also very confident in his strength, and that of his gang. An example of this is when he tried to fight Tatsumaki despite knowing that she is the S-Class Rank 2 hero.

Psychic Sisters Arc
Big Iron and his gang hold Erika hostage. Feather attempts to save her but is beaten down after defeating several members of the gang. Before Big Iron can finish the hero off, Tatsumaki sends Saitama flying through the wall and knocks out Feather. The Iron Fist members recognize Tatsumaki as the S-Class Rank 2 hero. Undeterred, Big Iron sees this as an opportunity to take her down and boost their reputation. He orders his gang to assault Tatsumaki before attacking Saitama to get him out of the way, but Saitama punches Big Iron, sending him flying through the ceiling.

Not much is known about Big Iron's strength. However, as an A-Class criminal, he is presumably quite powerful.
