Bukini has blonde hair with a red-dyed fringe. He wears a golden necklace, a white jacket with yellow edging and red lining, and pants with red flames on them. He also wears a belt with a Donquixote Pirates logoed buckle.
Bukini is a manipulative person, capturing a child's parents and forcing her to work for him and trick others into being captured as slaves to work in his weapons factory. He took on the persona of a show host to trick Paradise Island's visitors and tempt them with promises of fulfilling their dreams and giving them treasure. He would even try to remodel contest participants into loyal soldiers when they tried to use strength to win.
Working for the Donquixote Pirates, Bukini captured Homey;s parents and forced Homey to work for him. He developed the "KANAEMA SHOW", a fake contest to trick Paradise Island's visitors into competing for a large cash prize, but, in reality, participants were captured and forced to work in the island's underground weapons factory.
When the Straw Hat Pirates came to Paradise Island, Bukini pretended to be the host of the KANAEMA SHOW. However, Trafalgar Law was investigating the contest, suspecting that Donquixote Doflamingo had been funding it. Bukini was attacked by Lawa and the contest was interrupted, revealing Bukini's plot. Bukini's weapon factory was destroyed by Monkey D. Luffy, and the young pirate defeated Bukini with Gomu Gomu no Red Hawk. Bukini fell into a blast furnace in the factory's ruins below, causing a huge explosion.
His name may be a play on the Italian car manufacturer Lamborghini.
Bukini draws many parallels to the anime-only character Bill. Both are pirates who ate the Gutsu Gutsu no Mi, work for large antagonists to produce and provide resources (weapons versus silver), and are defeated by Luffy before falling to their doom into their own operation (factory versus mine).
