Brook

Brook (ブルック) is the musician of the Straw Hat Pirates and the ninth member of Luffy's crew. He meets the pirates when they found a ghost-ship while drifting in the Florian Triangle. Upon seeing him, Luffy immediately asked him to join his crew and Brook eventually agreed when his curse is lifted by Gekko Moriah's defeat.

Brook was once a member of the Rumbar Pirates. While traveling with them, Brook found a baby whale and named him Laboon. The whale could not follow them to Grand-Line and they had to leave him behind with the promise of returning one day. The crew of the Rumbar Pirates, including Brook, died in battle. Only Brook was resurrected due to his devil fruit ability, though his body became a skeleton by the time he discovered it.

Personality
While Brook claims to be a gentleman, in fact he possesses a very bad manners (such as regularly asking ladies to show their panties). Despite being a living skeleton, he is very afraid of ghosts. Also, he tends to make "skull jokes", which is based on the fact that he is dead. Brook, like many other characters, has his own distinct laughter (Yo-ho-ho-ho).

Being a musician, he is very fond of music and was called "Humming Brook" during his life.

Fighting Style
Brook is very capable swordsman and heavily relies on his speed during the fight. He can perform attacks so swift that some enemies may not even notice how much they've been cut until Brook sheaths his sword.
