"Dead Bones" Brook, is a musician. Brook is a living skeleton, resurrected by the Paramecia-type Revive-Revive Fruit, which grants the user a second life. He is an excellent musician, who claims to be able to play any instrument, although he is usually seen playing the violin. He is also a skilled fencer, who uses a shikomizue (a Japanese cane sword), in battle. Brook can hypnotize people with his music. His lightweight skeleton body allows him to jump extraordinarily high and to run across water. He has a very childish and energetic personality.
