Sanji is one of the most crucial members of the Straw Hat Pirates, both in terms of the role he serves on the ship and the battlefield. Sanji is a force to be reckoned with, and rightly so, given that he is one of the Wings of the Pirate King, and Luffy's very own number 3. He is incredibly powerful, and over the years, he has gone on to fight many characters and surpassed them as well.
