One Piece is in the Final Saga now and that means fans' most beloved characters are close to hitting their peaks and showing them the best versions of themselves. When it comes to the Straw Hat Pirates, Luffy has already become a Yonko of the Sea and, soon, he will rise to the same levels as the likes of Roger, the former Pirate King. The same logic applies to every other member of the Straw Hat Pirates as well and of course, Sanji is no different.
