Brook's POP! figure captures the enigmatic musician with a stylish and whimsical flair. The skeleton is dressed in a tailored black suit with a crisp white shirt, a bow tie, and a long cape that drapes behind him for drama. His tall top hat sits at a jaunty angle, framing a bright, friendly skull face with a classic empty grin and rounded eye sockets. He holds a slender cane in one hand, while the other rests at his side in a poised, confident pose. The base is compact, providing stable display. Overall, the figure conveys Brook's suave, theatrical persona while staying true to his skeletal form.

Brook is the musician of the Straw Hat Pirates, a living skeleton who was revived after a long absence due to the Yomi Yomi no Mi's powers. He travels with the crew aboard the Thousand Sunny, sharing songs and a philosophical humor about life, death, and friendship. Despite his calm, elegant demeanor, Brook is playful and occasionally mischievous, using his sword and musical talents to aid his friends in battles and emotional moments. His love of poetry, curiosity, and loyalty make him a cherished ally, and his memory of his crew drives his actions.
