Bonbon

Bonbon stands at ordinary height and wears his blond hair in a pompadour. His outfit features a vest styled after a peacock, loose white trousers, dark boots, and a cape colored black and red.

Matching his siblings, Bonbon is a brilliant but cold-minded scientist who carries himself in a cerebral manner. Compassion escapes him entirely, since he was glad to use his fruit's power to brainwash Nami into marrying his brother. He dreams that wielding his elder brother's ability would hand him dominion over the world.

Where his brothers excel physically, Bonbon is only average and relies on Misutta for protection. He consumed the Hore Hore no Mi, a Paramecia fruit that lets him make others fall in love with him using light and song.

Acting on Bürst's command, Bonbon and Misutta set out to seize Nami so that Bürst could wed her. They struck at the Thousand Sunny, and Bonbon used his power to enthrall Nami and carry her off. At Marriage Greenland, Brook posed as the officiant to spoil the ceremony, and his reveal stunned Bonbon. When the Straw Hats and their allies crashed the wedding, the scientist brothers took on Luffy and Sabo, falling to a combined Red Hawk and Hiken. What became of Bonbon and Bürst Lab after Bürst's imprisonment in Impel Down is unknown.
