Sanji is one of the most beloved characters that fans have seen in One Piece and he is certainly a very important part of the Straw Hat Pirates. Sanji possesses tremendous strength, and while much of that is down to the incredible training that he has gone through over the years, Sanji has also acquired scientific powers more recently. This is simply down to the fact that he was experimented upon when he was in his mother's womb, along with his other siblings.
