Brook is the musician of the Straw Hat Pirates. He is a skeleton the Straw Hats found on board a ghost ship after drifting into the Florian Triangle. He is a Devil Fruit user who ate the Yomi Yomi no Mi and is an undead being brought back into a pseudo-immortal state because of its powers. He fills the role of the long awaited musician that Luffy wanted for his crew since his journey began.
Brook is a great lover of music. Whether it be through happy or sad times, music is what generally keeps Brook going. As a result, his love for music often reflects itself in various other aspects of his character such as in his fighting style wherein the names of his attacks are derived from various musical songs and dances. He gave himself a musical theme so noticeable that while he was alive in his first life, he was called "Humming Brook" by the authorities.
Brook's devotion to music not only helped him to pass the lonely days but also serves as a combat tool. Most of the techniques that he deals out are named after or related to music. One of them even acts as a hypnosis that sends his enemies to sleep, however, this can also affect allies. Due to his musical background, Brook also moves according to the rhythm of music to assist him in battle, and soon became a world famous rock star during the past two years, at which point his records in tone dials were sold in millions and his fans on his final world tour in Sabaody Archipelago were either crying or fainting at his presence.Make Brook Playlist
