Sanji, born Vinsmoke Sanji, serves as the Straw Hat Pirates’ cook and a pivotal member of the crew. The disowned third son of Germa Kingdom’s former ruling family, he renounced his lineage after enduring their cruelty and rejection of his humanity. Rescued by the pirate chef Zeff, he honed his culinary mastery and martial artistry under his mentor’s guidance, forging the Black Leg Style—a combat philosophy prioritizing kicks to safeguard his hands for cooking.  
Driven by the quest to discover the mythical All Blue, a sea merging the world’s oceans, Sanji adheres to an unwavering chivalric code, refusing to harm women despite his flirtatious demeanor. Dormant genetic modifications, suppressed by his mother’s sacrifice, later awaken, granting him enhanced resilience and regeneration, though he grapples with the moral weight of these inherited powers.  
In the *Take Aim! The Pirate Baseball King* special, Sanji joins the crew’s baseball team as second baseman against the Fish-Men Pirates. His focus wavers under Nami’s attention, costing crucial plays, yet he unleashes a blistering kick that tears through his shoe and pant leg to strike the ball. Despite the spectacle, he forgets to run the bases, securing an out.  
His bounty escalates from 77,000,000 to 1,032,000,000 Belly, mirroring his infamy. Fiery rivalry with Zoro contrasts his fiercely protective loyalty toward Nami and Robin, reflecting his layered persona. Sanji’s journey weaves reconciliation of his traumatic past with Zeff’s teachings of compassion, rejecting his family’s legacy while embracing resilience. He frequently risks himself strategically, infiltrating enemies or shielding allies.  
In battle, Sanji ignites flames through friction with Diable Jambe and ascends air currents via Sky Walk, yet vows never to wield weapons or fists—his hands reserved solely for culinary artistry. Though prone to comedic romantic pursuits, his resolve to defend his crew and champion justice stands unshaken across every ordeal.
