Rayleigh joined the Roger Pirates as one of its founding members, becoming Gol D. Roger’s most trusted companion and first mate. As the “Right Hand of the Pirate King,” Rayleigh played a pivotal role in their journey to Laugh Tale, where the crew uncovered the secrets of the world and Joy Boy’s treasure. After Roger’s execution and the disbandment of the crew, Rayleigh chose a quieter life, settling on the Sabaody Archipelago and working as a ship coating mechanic.

Despite his retirement, Rayleigh maintained his influence and connections. He became the husband of Shakuyaku, a former pirate, and befriended Hatchan, a former Arlong Pirate. When the Straw Hat Pirates arrived on Sabaody, Rayleigh’s involvement reignited his connection to the next generation of pirates, particularly Luffy.

Rayleigh is an older man with a muscular build and a distinctive long, silver beard and hair, reflecting his age and nickname, the “Dark King.” His round glasses and casual attire, including a cloak draped over his shoulders, give him a relaxed but commanding presence. Despite his age, Rayleigh exudes vitality and strength, underscoring his legendary status.

Rayleigh is a calm, wise, and confident individual with a laid-back demeanor. His vast experience and knowledge make him a mentor-like figure to those he encounters. While retired, Rayleigh remains fiercely loyal to his friends and principles, willing to step into danger to protect those he cares about. He has a playful side, often displaying humor and humility despite his immense reputation.
