Buena Festa, titled "Master of Festivities," captained the Festival Pirates and acted as a key instigator in *One Piece: Stampede*. His background included fame as a pirate renowned for organizing grand parties that masked secret merchant networks and underworld deals. Before the film's events, he was presumed dead. Following Gol D. Roger's execution, Festa hid for 22 years until discovered by Douglas Bullet, a former Roger Pirates member. Together, they secured an Eternal Pose crafted by the Roger Pirates, directing them to Laugh Tale (formerly Raftel), the island holding the One Piece. Over two subsequent years, Festa and Bullet meticulously orchestrated the Pirates Festival, luring powerful pirates to Delta Island with the promise of Roger's lost treasure. Their ultimate aim was to harness Bullet's might to eliminate these pirates, terminate the "Great Age of Pirates" begun by Roger, and forge a new era under their dominion. Festa exhibited ambition, derangement, and warmongering traits. He burned with envy toward Gol D. Roger for creating an era—which he called the "greatest festival"—he felt he could never surpass. This envy drove his desire to bury Roger's legacy and incite global upheaval through chaos. His behavior was excitable and chaotic, demonstrated when he sprinted across a table upon spotting the Straw Hat Pirates' arrival. Festa showed deep investment in his schemes, growing annoyed when subordinates like Cidre deviated from his designs, such as attacking Monkey D. Luffy prematurely; Luffy was meant to be a central attraction. Festa's organizational prowess, evident in the elaborate Pirates Expo and treasure hunt execution, earned him his "Master of Festivities" moniker. During the Pirates Expo on Delta Island, Festa served as primary promoter and host. He collaborated with Bullet to manipulate participants into competing for Roger's treasure, later unveiled as the Eternal Pose to Laugh Tale. To trap everyone, Festa engineered a covert Buster Call by the Marines, intending to annihilate all gathered pirates and Marines once Bullet engaged them. From a hidden tower, he monitored the chaos and contacted the Emperors of the Underworld via video. He revealed Bullet possessed the Eternal Pose, declared their intent to end the pirate era, establish a new world order, and eliminate the Four Emperors. His plan relied on Bullet's overwhelming power and the treasure's allure to concentrate the world's strongest pirates for eradication. After Bullet's defeat by Monkey D. Luffy and allied pirates and Marines, Festa's scheme crumbled. He voiced regret over his failure, wishing he had allied with Luffy instead. In final defiance, he attempted to shoot Sabo of the Revolutionary Army with a flintlock pistol. Sabo swiftly defeated him using his "Hiken" (Flame Fist). Festa was subsequently captured by the Revolutionary Army and arrested, concluding his plot to reshape the world. His name, "Buena Festa," combines Spanish "good" and multiple languages' "party," reflecting his persona as a purveyor of grand, destructive celebrations.
