Sanji is one of the most important characters in One Piece and certainly among the strongest on the seas. Although often mistaken for being just a cook, Sanji is actually a cook who fights, given that he grew up on Baratie, which was often frequented by the mightiest of pirates and Marines at the same time. As such, Sanji was always going to be one of the biggest fighters in the story, and among the most important ones in the Straw Hat Pirates as well.
