"Black Leg" Sanji,[12] born as Vinsmoke Sanji,[21][22][23] is the cook of the Straw Hat Pirates and one of the Senior Officers of the Straw Hat Grand Fleet.[5] He is the fifth member of the crew and the fourth to join, doing so at the end of the Baratie Arc. 

He first gained a bounty of 77,000,000 for his role in the raid on Enies Lobby. It increased to 177,000,000 after the Dressrosa Arc, but the condition of his bounty was changed to Only Alive due to his biological father's interference. After he escaped from Big Mom's territory, his bounty condition was reverted back to Dead or Alive, and its value increased to 330,000,000.[19] Following the Raid on Onigashima, his bounty was increased to 1,032,000,000.[5] Despite renouncing his surname Vinsmoke,[22] the World Government labels it as part of his name on his wanted poster.[23]
