Brook

Brook (ブルック) is a musician of the Straw Hats 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. Once seeing him Luffy immediately asked him to join his crew and Brook agreed. He later aids the Straw Hats in their fight against Gekko Moriah.

Brook was once a member of the Rumbar Pirates. While being with them, Brook found a baby whale and named him Laboon. However, Laboon could not follow them to Grand-Line. They had to leave him behind, promising that they'll return to him one day. Unfortunately, the crew of the Rumbar Pirates, including Brook, died in battle. Only Brook was resurrected due his ability, but ended up being a skeleton and later had his shadow stolen by Gekko Moriah. With Luffy's help, he was able to obtain it back and decided to follow his lead.

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.
