The cook of the Straw Hat Pirates, Sanji is an incredibly important member of the group. Joining up with Luffy in the Baratie Arc, Sanji has since then gone on to establish himself as one of the most important members of the crew. Not only is Sanji the cook of the ship, but he is also an incredibly powerful fighter, consistently being one of Luffy's two strongest men, alongside Zoro. Sanji's also a brilliant strategist, quite easily being the best in the crew in this regard.
