Brook (ブルック, Burukku), nicknamed "Dead Bones", is the musician of the Straw Hat Pirates. He is a skeleton, resurrected by the Revive-Revive Fruit (ヨミヨミの実, Yomi Yomi no Mi), a paramecia-type devil fruit, which grants its eater a second life. He is an excellent musician, who claims being able to play any instrument, and a skilled fencer, who uses a shikomizue, a Japanese cane sword, in battle. His lightweight skeleton body allows him to jump extraordinarily high and to run across water. His gentlemanly impression stands in stark contrast to his incredibly bad manners: He bluntly requests to see women's panties, helps himself to people's food, and belches out loud on the dinner table, he also likes to make jokes like "I'm going to die; wait, I'm already dead". When Brook's former crew, the Rumbar Pirates, entered the Grand Line, they left their pet whale Laboon behind at Reverse Mountain, promising to return after sailing around the world. Fifty years later, Brook, being the only survivor, considers it his duty to fulfill his former crew's promise.
