Bartolomeo, nicknamed "The Cannibal," commands the Barto Club as a pirate captain and serves as a key member of the Straw Hat Grand Fleet. Once a ruthless East Blue mob boss, his life pivoted when witnessing Monkey D. Luffy’s near-miraculous survival at Loguetown’s execution platform—an event that ignited his fervent devotion to the Straw Hat Pirates. He venerates Luffy and his crew with exaggerated honorifics like “-senpai,” often tearing up during encounters with them. His personality blends vulgarity, provocation, and nonchalance, marked by taunting adversaries and flouting societal norms. Yet he fiercely protects allies, exemplified by his intervention to rescue Bellamy from execution in Dressrosa and brutal retaliation against Vice Admiral Maynard for attacking his subordinate Gambia. He adheres to a personal code, prioritizing loyalty over profit and refusing to desert comrades. The Bari Bari no Mi Devil Fruit grants Bartolomeo the power to create near-unbreakable barriers by crossing his fingers, capable of deflecting even the King Punch. Limited to one barrier at a time, he employs these shields strategically, baiting foes into overextending before countering with calculated precision. During *One Piece: Stampede*, Bartolomeo joins the Pirates Festival’s hunt for Roger’s treasure on Delta Island, collaborating with the Straw Hats and deploying moves like “Barrier Bulls.” His ship, the *Going Luffy-senpai*, boasts dark crimson sails and a Luffy-shaped figurehead. After Bartolomeo burns the Red Hair Pirates’ flag, Yasopp destroys the vessel, though Shanks grants him clemency. Distinctive traits include his speech suffix “-dabe,” a cackling “Hehehahahaha” laugh, a light-green Mohawk, sharp fangs, septum piercing, and tattoos beneath his right eye. He typically wears a plumed dark-purple coat and checkered trousers. Narrative arcs highlight his transformation from reckless gangster to a Straw Hat Grand Fleet cornerstone, melding crude antics with unshakable loyalty to Luffy and his own crew’s survival.
