Brief

Brief is a character that appears in the sixth movie, Baron Omatsuri and the Secret Island.

He is an unofficial occupant on Omatsuri Island, first seen spying on the Straw Hats during the "Goldfish Dipping" game. He later meets up with Luffy and ask him to join his crew called the Moustache Pirates, also warning Luffy to be wary of the Baron. He later saves Luffy from being captured by the Baron during the "Shooting" game, and again when the Baron is on the verge of killing Luffy.

It is later revealed that his Moustache crew fell victim to Lily, and he begged the Baron to spare his life. However, he refused to let it happen to Luffy's crew and helps Luffy by first snapping him out of his despair when he believes his crew dead, and then distracting the Baron while Luffy gets close to the monstrous Lily carnation.
