Scorpion is a middle aged man, with brown hair and a beard. He also has an arrowed-heart tattoo on his forehead. In his bounty hunter outfit, he has a black helmet with a red scorpion mark and wears a squared red shirt, black long-sleeved undershirt, knee-length overalls with pants underneath, and brown shoes.
The Prescorraci Rifle (消化作銃,Shōka Sakujū?) is Scorpion's personal weapon. It is a backpack weapon that can shoot acid (a compressed extinguisher foam in the 4Kids) from its target hose. Ace manages to escape the acid shot at him, but it is shown to be powerful enough to break through rock.
He can also shoot a very strong bomb, that, upon contact with a surface, will protrude spikes from its shell to stick to the surface before detonating. He also has a steel net that can be shot out of his bazooka.
After hearing his sons wishing for a better life, he tried to capture Portgas D. Ace (after luring him there with rumors that he had defeated Blackbeard). He fought with Ace using a bazooka that can shoot a steel net, a high pressure acid gun, and a polka-dotted bomb that can blow up a mountain. When a landslide was about to crush him and his boys, Ace saved him with his Hiken and he went back to raising his sons after telling Ace about Blackbeard's last whereabouts.
