Gorilla

Captain Gorilla (ゴリラ大佐, Gorira Taisa) is a Marine officer who was sent to investigate the Nightmare of Barujimoa accidentally caused by Franky.
His face remarkably looks like his namesake, a gorilla. He has hairy sideburns and a big, particular nose that resembles those of gorillas. On his head he has a standard Marine cap. He is dressed in an attire fitting the cold climate of the island he was sent to investigate. He sports a fur-lined cape with the Marine insignia on it and epaulets over what looks like a long coat with pockets on it. On his back he carries a standard flintlock rifle.
First Appearance: Chapter 596
