In this article, we will talk about a hypothesis that has been the subject of controversy among many followers of the manga One Piece Black Leg Sanji, and why exactly is this nickname? We've always seen great consistency in the events Oda narrates, leaving hints of all future events, and of everything that is supposed to happen. Oda has always been thought, clever, and malicious in changing fan assumptions.  The name Black Leg is associated with fire and heat. At the beginning of the story, and before joining the Straw Hat crew as a new member, he was working in a restaurant under the supervision of his critic, Ziff Red Leg.The person who taught him how to kick and use new techniques in one-on-one combat throughout his journey with Luffy, where he fought several battles, the first of which was against the crew of Arlong in the East Blue.

 

 

After this deadly battle, Sanji's fame increased and he gained a lot of experience, becoming the third man in terms of strength after both Luffy and Zoro.

But despite all this strength gained at the beginning of the story that Sanji still has a fatal weakness that has not always been an obstacle to him and his friends in the crew, namely the women, as we have mentioned in many situations that he cannot fight them and this has recently appeared in Wano in front of Black Maria one of the Tobiroppo Despite the two-year period and extensive training with Ivankov, he could not get rid of her.

As we delve into the story and reach the Water Seven Enies Lobby, Sanji's strength and courage began to grow as he was the first to confront Cp9 and stand in their way, to be able to demonstrate the diable jumbe technique for the first time, which was important in his fight against Jabra. As we entered Thriller Bark and in some battles, we caught fire sanji's feet, and this was shown more in Return to Sabaody where this fire was clearly and large, but the reason was unknown and illogical, how can a person who does not eat devil fruit set his feet on fire but I am in Zu and after kidnapping sanji by the Big Mom pirates and Germa66 appeared in the story, things started to become clear, especially after the appearance of Flash back sanji.

We have seen the miserable childhood that Sanji lived with his four brothers as he suffered from oppression and persecution because he was considered a failed experiment in the Germa66 scheme.

 

 

 But in the whole cake island arc and during the escape process by the Big Mom pirates, Sanji got his number 3 suit, which will be tried for the first time on Wano Island, which gave him high speed to the limits of invisibility, increasing the hardness and fire power. Wearing the suit was the catalyst that awakened the hidden power of the sanji and moved his hormones. The thing that gained him more power enabled him to dispense with the suit permanently. This was revealed in his fight against the queen to give us the terrifying toughness and ability to recover, which are the things that sanji was lacking In addition to the power of blue fire that was the only way to defeat the Queen .
