Sanji And The All Blue

Sanji from One Piece
Each member of the Strawhat Pirates has a unique dream they work towards. Luffy, the captain, aims to find the One Piece and become the Pirate King. The chef Sanji desires to discover the All Blue – a legendary sea with various fish from the four seas.

As the head chef of the Strawhat group of Pirates, Sanji’s dream is closely linked to his passion for cooking. He believes that finding the All Blue would be the ultimate achievement of his culinary career.

The Five Elders and The All-Blue

Developments in the manga showed that someone may have been hiding the All Blue in the Grand Line. The culprit is someone from the Gorosei.

In the present Egghead Island Arc in the manga, The Five Elders invaded the island and revealed their devil forms to attack Dr. Vegapunk. One of the Gorosei, Saint Ju Peter, seemed to resemble a creature from another famous book, the sandworm from Dune. 

These creatures are known for their weakness to moisture and can be killed if drowned in water. Fans on X, formerly known as Twitter, speculated that of the Gorosei, Saint Ju Peter seems the most likely of them to hide the All Blue as it could be his ultimate weakness. But a fan had an interesting theory in mind about the real purpose of why the all blue is hidden.

Devil Fruits and the All Blue

Sanji from One Piece
Any viewer of One Piece knows of one of the most famous weaknesses of the powerful devil fruit users: the sea.

The condition for receiving the power of a devil fruit is that the user will forever lose the ability to swim. Any contact with seawater renders the user unable to activate his powers and defenseless. Seastones extracted from the sea can also nullify the powers of devil fruit users.

A fan on X theorized that the All Blue, the body of water where all the seas intersect, could have a higher effect on devil fruit users than normal seawater. It could have the power to completely lift the curse of a Devil Fruit, rendering the user accessible of their powers.

Could the All Blue possess the power to erase the existence of every Devil Fruit power that ever existed? We hope the mystery of the All Blue receives a deserving conclusion.
