Humphrey is a large man with fuzzy black hair (with a bald spot in the front) and sideburns. He wears a white shirt that is unbuttoned.
Humphrey is first seen giving a drink to Nami after she returned to Sabaody Archipelago. He gave her some information on the New World, including the relocation of Marineford. He advises Nami not to mess with the Impostor Straw Hat Pirates, but his bar is all but destroyed when Nami strikes it with a thundercloud.
