Sanji has only one obstacle on his way to find the All Blue

SUMMARY

Since childhood, Vinsmoke Sanji has dreamt of finding the All Blue, where all the four seas joined and there were several types of marine life to be found.
A ‘One Piece’ fan theories claims there is only one obstacle in front of Sanji on his way to fulfil his dream and the obstacle is none other than one of the Gorosei.
People with strong will and grand dreams can unlock Conqueror’s Haki, so Sanji might unlock it in his final fight against the Gorosei to find the All Blue.

The Egghead Island arc is approaching its climax, with Monkey D. Luffy having to face all the Five Elders at once. After Saint Jaygarcia Saturn summoned all the other members of the Gorosei, they instantly transformed into their Devil Fruit forms and started to wreak havoc throughout the island. One of the Gorosei, Saint Shepherd Ju Peter, tried to swallow Luffy but was saved by Dorry and Brogy.

With fan theories often popping up relating to several One Piece mysteries, the latest one claims that Saint Shepherd Ju Peter could Vinsmoke Sanji’s final opponent since he might know the secrets to All Blue. Since childhood, Sanji dreamt of discovering the All Blue. Being so close to finding it, he might not let it slip.

Sanji vs. Ju Peter Might Happen

After Ju Peter arrived on Egghead Island, he transformed into his Devil Fruit form, Sand Wyrm, which is a sandworm. He is the Warrior God of Agriculture, which could signify his Devil Fruit powers since sandworms travel through the soil and irrigate it for better plantation. Moisture is one of the greatest weaknesses of sandworms and earthworms since they die after drowning in water. So, he might have removed or hidden the All Blue since it was poison to his existence.

The fan theory claims Devil Fruit users become deadweight in the sea, but All Blue might have special qualities that cancel the Devil Fruit abilities and make the user flow on the water. In simpler words, it is a cure for the sea weakness of the Devil Fruit users. But the existence of such a thing could nullify the monstrous abilities of the Gorosei. So Saint Shepherd Ju Peter, being the Warrior God of Agriculture, removed All Blue or hid it somewhere so that they could reign supreme.

Vinsmoke Sanji’s dream is to find the All Blue, so Saint Shepherd Ju Peter could be his final opponent in One Piece due to the fact he might know All Blue’s whereabouts. It is one of the grandest dreams in One Piece. With both the parties present on Egghead Island, there is a possibility that the fan theory can take the shape of reality.

Sanji Could Unlock Conqueror’s Haki against His Final Opponent in One Piece

Monkey D. Luffy and Roronoa Zoro had one of the grandest dreams. People with strong wills and great ambition can unlock Conqueror’s Haki. Taking that logic into consideration, the One Piece fan theory claims Sanji could also unlock Conqueror’s Haki. It could be the perfect way to set up this ability. His unlocking the Conqueror’s Haki to fulfill his dream of finding the All Blue would be justice to his character.

The theory also claims Saint Ju Peter to have similarities with Liet-Kynes from Frank Herbert’s Dune. Their appearances are the same, and they are both related to agriculture. Moreover, there are giant sandworms in Dune, who are referred to as Gods, bearing similarities with the mentioned members of the Gorosei. One Piece chapter 1073 featured Saint Jaygarcia Saturn traveling to Egghead Island with Admiral Kizaru.

While serving him food, Kizaru ordered one of the Marines to check the food for poison. Saint Jaygarcia Saturn has instant regeneration and massive immunity, so there is no point in checking for poison in his food. It could be that a drop of All Blue could erase his abilities, and it is being referred to as poison.
Saint Shepherd Ju Peter’s Devil Fruit form
Eiichiro Oda has given several hints about Sanji unlocking Conqueror’s Haki soon. With Saint Shepherd Ju Peter in between him and his grandest dream, he might reach his full potential to defeat the monstrous member of the Gorosei. But hints won’t do since proper confirmation is required from the creator himself. Until then, fans will have to rely on theories.
