Laffitte

Laffite (ラフィット, Rafitto) is the navigator of the Blackbeard pirates.

Appearance
He is incredibly pale and sickly looking, yet is very stealthy and tap-dances while he walks.

Abilities and Powers
As a navigator, Lafitte guides the rest of the Blackbeard pirates through the open seas. He apparently ate some sort of Devil Fruit that allows him to transform his arms into wings and fly.

Past
He used to be a policeman in West Blue, but he became a pirate after being exiled from the police force and banned from the West Blue for being excessively violent and cruel.

Jaya Arc
In the current storyline, he first appeared when he joined, unannounced and uninvited, and not to mention for a while unnoticed, at the meeting of the Shichibukai to determine the replacement for Crocodile in order to recommend his captain.

Post-Enies Lobby Arc
He is seen again when Ace appears having finally caught up to Teach. Mainly, he acts as a bystander, doing nothing to try to hinder Ace's progress, unlike his fellow crewmates Van Auger and Jesus Burgess.

Trivia

 * His name may have been inspired by Jean Lafitte, a famous real-life pirate.
