Captain Nezumi (ネズミ大佐 Nezumi Taisa) is a Marine Officer stationed at the 16th Branch in the East Blue. His appearance and demeanor are reminiscent of a rodent, fitting for his name, which means "mouse" or "rat" in Japanese. He is characterized by his arrogance and corrupt nature. Nezumi accepts bribes from Arlong, allowing the Fishman pirate to operate without attracting much attention. Acting on information provided by Arlong, Nezumi discovers the treasure Nami had been collecting to buy back Cocoyashi Village and confiscates it. After Arlong's defeat, Nezumi tries to interfere with the Straw Hat Pirates but is swiftly defeated and forced to return everything he stole.
His report to his superiors about these events leads the Marines to issue Luffy his first bounty. First Appearance: Chapter 69; Episode 31. (Source: One Piece Wikia)
