Scorpion

Scorpion (スコーピオン, Sukōpion) is a bounty hunter who lives in the Badland in Alabasta after retiring there to raise his two sons, Chip and Dip.

After hearing them wishing for a better life, he tries to capture Portgas D. Ace (after luring him there with rumors that he had beaten Blackbeard). He fights with Ace, using a bazooka that can shoot a steel net, a high pressure acid gun (changed to water in the 4Kids dub), and a purple polka-dotted bomb that can blow up a mountain. When a landslide is about to crush him and his boys, Ace saves him with his Fire Fist technique and he goes back to raising his sons, after telling Ace about Blackbeard's last whereabouts. He also has an ostrich named Popo that he rides around on. He fights with a weapon he created called the Prescorraci Rifle.

Prescorraci Rifle
The Prescorraci Rifle is Scorpion's personal weapon. It is a backpack weapon that can shoot acid from its target hose. Ace manages to escape the acid shot at him.
