American Thugs

This trio of hired guns hails from the USA and consists of three siblings: an unnamed eldest, the middle brother Joey, and the youngest, Aldo. Orphaned when the Gun Devil's first rampage claimed their parents and grandmother, the survivors drifted into assassination as a means of survival. A string of brushes with death, being eaten by a devil, having their home torched, surviving food poisoning, hardened them into the conviction that they simply cannot die, a belief they wear like armor.

The American government contracted the brothers for two million dollars to track down the Chainsaw Man's heart and bring it back to the States. During the International Assassins arc, they ambushed a carload of Japanese hunters, Michiko Tendo, Yutaro Kurose, and Subaru, gunning them down after forcing the vehicle off the road. The eldest used the Skin Devil to impersonate Kurose and infiltrate Denji's escort, but he was accidentally killed when Power rammed the group with Kobeni's car, exposing the disguise. Joey was slain shortly after by Hirofumi Yoshida. The lone survivor, Aldo, kept up the Kurose persona, even spending an evening with the dead man's grieving friend Tomono. Aldo later resurfaced at the department store battle, firing on Long to free Denji before Quanxi flung him out a window, after which he witnessed the Hell Devil banish everyone inside to Hell. He is last glimpsed among the crowd of puppets murmuring Halloween, seemingly mind-controlled, though his expressions hint he may simply be playing along to stay alive.

The eldest brother, who remains unnamed, led the group and wielded the Skin Devil's shapeshifting before dying first. Joey, the middle sibling, was killed by Yoshida while attempting to return to the crowd in a rage. Aldo, the youngest, is the only one of the three to survive the events of the arc.
