Laffitte

Laffite (ラフィット, Rafitto) first appeared when he joined, unannounced and uninvited, at the meeting of the Shichibukai to determine the replacement for Sir Crocodile in order to recommend his captain. 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. He is incredibly pale and sickly looking, yet is very stealthy and tap-dances while he walks.

He is seen again in chapter 433 with the rest of his crew. Mainly, he acts as a bystander, doing nothing to try to hinder Ace's progress, unlike his fellow crewmates Van Auger and Jesus Burgess.

According to his character discription in Volume 46, he was revealed to be a navigator for the Blackbeard Pirates.

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