Brief

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

Appearance
He is a relatively short middle-aged man with brown hair and a thin toothbrush moustache. He wears a beige safari helmet with a dark-brown band around it. His formal attire consists of a white shirt with bow tie under a black jacket with yellow shoulder pads. He also wears thick black spectacles at all times.

Personality
Brief comes across as a kind individual but his stay at the 'vacation' island has clearly had an effect on him: he seems quite lonely with the loss of his crew and asked Luffy to join him several times at no success. He is also clearly compassionate and friendly as, despite these refusals, he still helps Luffy through his despair and then aids him in taking down the Baron.

Monkey D. Luffy
While hiding on the island, he meets and befriends Luffy who bands together with him and the other remnants in order to defeat Omatsuri.

Crew
Not much is known about the Moustache Pirates beyond that they were very close and not against goofiness on occasion (if the call-sign is any indication). Brief seems to have had a very positive relationship with them and misses them greatly, but not so much that he will not befriend any others.

Abilities and Powers
As a captain of a crew of pirates, it can be assumed that Brief possessed a reasonable amount of fighting skill, or at least leadership skill. He is also quite adept at the construction of tunneling passageways through the ground.

History
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 asks 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.
