Brook

"Soul King" Brook serves as the Straw Hat Pirates' musician and one of their two swordsmen. He holds the title of Senior Officer within the Straw Hat Grand Fleet and occupies the ninth position in the crew, being the eighth to officially join during the culmination of the Thriller Bark Arc. Brook consumed the Yomi Yomi no Mi, granting him the unique ability to resurrect after death. This Devil Fruit enables him to gain greater mastery over his own soul and the souls of others as he continued his journey.

Originally a member of the Rumbar Pirates, Brook met an untimely demise but was granted a second chance at life through the Yomi Yomi no Mi's power. Unfortunately, the passage of time left only his skeletal form, preserving his distinctive afro. Brook endured fifty solitary years in the Florian Triangle before crossing paths with Luffy and becoming a vital ally during the Thriller Bark Arc. His ultimate aspiration is to reunite with his long-lost friend, Laboon, residing alongside Crocus at Reverse Mountain. Brook's bounty reached 33,000,000 Beli during his tenure with the Rumbar Pirates, and it escalated to 83,000,000 Beli following the Dressrosa Arc. After the Raid on Onigashima, his bounty further increased to 383,000,000 Beli.

As a virtuoso musician, Brook's instrumental prowess extends to various instruments, with the violin being his favorite. After parting ways with the Straw Hats for a period, he mastered the guitar, becoming a globally renowned rock star within two years. His records on Tone Dials achieved immense popularity, drawing countless fans during his final world tour in the Sabaody Archipelago. Brook possesses the remarkable ability to play enchanting melodies capable of captivating even creatures like Laboon, who would harmonize with his music. In addition to his musical skills, Brook is a talented composer, responsible for hit songs like "Bone To Be Wild" and "New World," adored by music enthusiasts.

Brook's commitment to music extends beyond entertainment; he has harnessed its power for combat purposes. He employs a technique known as "Nemuriuta Flanc," strumming his violin with his shikomizue instead of a violin bow to create a soothing tune that induces immediate sleep in those who hear it. His music possesses the capability to influence emotions and attitudes, inspiring resistance in the face of adversity, as witnessed on Namakura Island. During a confrontation with the New Fish-Man Pirates, Brook demonstrated the ability to manipulate the mood to such an extent that he convinced his opponents they were in the midst of a festive celebration, leading them to misuse their cannons as fireworks.

With an acute understanding of musical elements such as rhythm, beat, and tempo, Brook possesses exceptionally sharp hearing, allowing him to discern sounds accurately. Even while dealing with invisible opponents like Zeo, he could pinpoint their locations based on sound alone.

Brook's consumption of the Yomi Yomi no Mi provided him with the ability to reunite his soul with his skeletal body after death. He can temporarily separate his soul from his body, enabling him to move independently and pass through solid objects. If his skeletal form is damaged, he can employ soul tendrils to reassemble the severed parts. Furthermore, Brook can exert his soul's power to overpower beings with weaker souls, such as Homies.

His soul energy emanates intense cold, referred to as the "chills of the Underworld," and he can imbue objects, including his sword "Soul Solid," with this freezing aura. This ability allows him to freeze his surroundings, as evidenced on Zou. Additionally, Brook's swordsmanship skills have evolved significantly, earning commendation from a samurai in Wano. He can now perform flying slashes comparable to those executed by Zoro and Kin'emon, even cutting through materials harder than steel, as demonstrated by his encounter with a dragon.
