Jean-Pierre Polnareff, a Stand user first introduced in *JoJo's Bizarre Adventure: Stardust Crusaders*, undergoes a harrowing transformation by *Golden Wind*. Severely injured in a clash with Diavolo, leader of Passione, he loses his legs and right eye, relying on prosthetics and a wheelchair. While investigating Passione, he unearths a Stand Arrow that inadvertently transforms Silver Chariot into Silver Chariot Requiem—a chaotic entity triggering soul-swapping and fatal injuries during another Diavolo encounter. Polnareff’s consciousness merges with Coco Jumbo, a turtle gifted to Team Bucciarati, after Silver Chariot Requiem’s soul-transfer ability activates. The turtle’s Stand, *Mr. President*, harbors a hidden room within its shell, serving as the team’s refuge. Irreparable damage to his original body permanently binds Polnareff’s soul to Coco Jumbo, allowing him to communicate and guide allies from this new form. In *Golden Wind*, Polnareff strategizes against Diavolo, leveraging knowledge of King Crimson and the Arrow. Despite physical constraints, he orchestrates pivotal actions, including guiding Giorno Giovanna to evolve Gold Experience into Gold Experience Requiem, ensuring Diavolo’s downfall. Post-battle, Polnareff’s soul remains within the turtle, guarding the Arrow and vital knowledge from the Stand-crafted room. His arc shifts from brash warrior to tactical mentor sacrificing his humanity, embodying resilience. Merged with Coco Jumbo, he personifies themes of identity and legacy, influencing events beyond his physical form.
