He is the navigator of the Blackbeard Pirates.
He lived in West Blue and worked as a policeman, but was exiled because he was excessively cruel and violent. Like the rest of the Blackbeard Pirates, Laffitte believes strongly in luck, fate, and dreams.
It is expected that he is a reasonably good navigator to navigate through the Grand Line. Interestingly enough, despite his occupation, he is not seen wearing a Log Pose, which is essential for navigating in the Grand Line.
He also is able to move in a similar fashion to the Soru technique as shown in Blackbeard's fight with Ace. He infiltrated Mariejois and bypassed detection from several high ranking Marines and Shichibukai while wearing tap shoes (anime-only feature), until he intentionally made his presence noticed. It was stated during the Marineford Arc that he was able to hypnotize marines to open the Gates of Justice for them.
