Brook is rendered as a striking living skeleton wearing a tailored black tuxedo, crisp white shirt, and a glossy red bow tie. The Grandline Men styling captures his signature charm, including an impeccably sculpted skull with a friendly, mischievous smile and the iconic round glasses perched on the nose. His large afro hair is carefully shaped, with subtle shading to suggest texture and volume. The figure balances on a slender, ornate cane that doubles as his weapon, with a poised hand resting on it. The suit shows detailed lapels, waistcoat, and crisp cuff details, while the legs and feet are shaded to reveal bone structure beneath the fabric. The paintwork highlights tiny bone joints and dramatic black-to-silver transitions on the cane and shoes. A thematic display base completes the pose, suggesting motion and stage presence.

Brook, known to the crew as the music-loving, perpetually upbeat living skeleton, hails from an era long past yet remains inseparable from his friends who sailed with him. He joined the Straw Hat Pirates after a fateful voyage that sealed his friendship with them and helped him recover from a lonely, half-century slumber. A gentle scholar of melody, Brook spends his days weaving tunes from memory, cherishing every note as a link to comrades lost and ships that drifted from sight. His revival by the Revive-Revive Fruit left him with a love of laughter, a haunting sense of irony, and an undying devotion to friendship. In Wano Kuni, Brook continues to perform, share stories of the sea, and face dangers with a poised grin, translating his cool demeanor into both humor and courage as his crew survives beside him.
