This article contains spoilers from One Piece's Elbaf Arc.

The Final Saga of One Piece is well and truly underway, and fans know that in this part of the story, the Straw Hat Pirates will go on to reach their maximum potential as well as fulfil all their dreams. This applies to everyone, including the chef of the Straw Hat crew, Sanji. Fans know Sanji to be one of the strongest members of the Straw Hat Pirates, being one of the Wings of the Pirate King who will help Luffy reach the very top. His importance has already been established by Oda as second only to Luffy in the crew, equal to Zoro, and that goes to show his value in the Final Saga.

Sanji is already an incredible asset to the crew, but it goes without saying that the level at which he is at the moment is not enough. If Luffy truly is to become the King of the Pirates and, more than that, topple the regime of Imu, then Sanji needs to be much more than what he is at the moment. That is precisely why Sanji will go on to reach newer heights in the next arcs of One Piece, and Oda has already readied his Yonko-level power-up that will help him fight the elites of the One Piece world with ease.

Sanji Is Closing In On Yonko Level

  • Sanji Has Powerful Haki At His Disposal
  • His latent Germa powers have awakened
  • Sanji's full powers are slowly showing

It is no surprise to know that Sanji is closing in on Yonko level with each enemy that he fights. Before the Wano Arc, Sanji was already quite strong, but he hadn't received any major power-up apart from the two basic Haki types during the timeskip. However, Wano marked a significant change for Sanji's character. He received the Raid Suit from Germa 66, and this power allowed him to activate the latent genes inside his body, unbeknownst to him. When Sanji destroyed the Raid Suit, he believed that he had bid farewell to the Germa forever, but little did he know that his body's latent modifications had awakened.

I gained an exoskeleton, a high regeneration rate, and muscle mass. Combined with the highly refined Armament Haki that I've developed over the years, my legs can sustain hotter flames. — Sanji

Sanji gained a powerful exoskeleton and an incredible regeneration rate, but he did not go on to lose his emotions like his brothers. When this power of his was combined with his incredible Armament Haki, Sanji was able to develop new powers such as Ifrit Jambe, and destroy even a Queen in battle with low difficulty. Sanji's strength was such that it couldn't be matched by even Yonko Commanders, and logically, one would assume that this is his peak. But, Oda is clearly establishing even greater power-ups for Sanji.

Unlike the other Yonko, Luffy has to go beyond and become the Pirate King, just as Sanji must go beyond the average Yonko Commander as well and close in on Yonko level. In the Egghead Arc, Sanji clashed with Kizaru and absolutely shocked him by destroying his lasers completely. This was a glimpse of what Sanji can achieve in the future, and fans cannot wait to see what comes next for him in Elbaf.

Sanji Will Finally Get His Yonko-Level Power Up In Elbaf With Conqueror's Haki

  • Oda has set up Sanji getting Conqueror's Haki as his biggest power-up
  • Sanji will grow significantly in the Final Saga

The Elbaf Arc has laid heavy focus on Conqueror's Haki already. Given that the Holy Knights and the Demon Army are the enemies in this arc, it is quite clear to see that the usage of Conqueror's Haki is going to be absolutely essential here. That is precisely why the likes of Luffy, Zoro, and Sanji will be very important. Luffy has already mastered Conqueror's Haki to a certain degree. Zoro, despite not knowing he had it, was using it thanks to Enma. Meanwhile, Sanji never used this power before in his life, but Oda has clearly highlighted the fact that Sanji is closing in on this power and will go on to unlock it very soon.

I feel that I have the power of the Supreme King Haki in me. — Sanji

This arc is going to be the training ground for both Zoro and Sanji to master their Conqueror's Haki and be able to damage the Holy Knights of the One Piece world. If they truly are to stand side by side with Luffy and become worthy of being the Wings of the Pirate King, then they truly need this power-up. While Zoro only needs to control it, Sanji first needs to awaken it, and that is precisely what the Elbaf Arc is for.

Once Sanji awakens his Conqueror's Haki and goes on to utilize it in battle, fans will truly see him as an elite pirate who can stand his own even against the likes of the Yonko of the One Piece world. Whether fans like it or not, Sanji will be a Yonko-level individual come the end of One Piece, and that is a given. He has to surpass the likes of Scopper Gaban and Rayleigh, because the new era always topples the old one.

If Sanji masters Conqueror's Haki in the Elbaf arc, then it can safely be said that at the end of the arc, he will be one of the strongest on the seas. Sanji should be able to fight and defeat the Admirals after Elbaf which means that he should also be Yonko-level. This doesn't surprise any fan, given where One Piece is at the moment.

In the future, the biggest enemy of the Marines is going to be me, Black-Leg Sanji! — Sanji

The Elbaf Arc will mark the beginning of the Great War, and Luffy will only be one step away from the Final Island, Laugh Tale. It is at this point that all the Straw Hats need to reach their maximum potential, and that includes Sanji as well. Zoro should be at the level where he can fight and beat Mihawk after Elbaf, and, as such, it shouldn't come as a surprise to any fan that Sanji would be Yonko level as well.

It is only a matter of time before Luffy and his wings make a great name for themselves across the seas. In the war against the World Government, these three will shine as some of the strongest individuals in the entire world, and they will dismantle Imu's demon army. Truly, it is an incredible time to be a fan of Zoro and Sanji, because these magnificent fighters will go on to reach incredibly high levels in the Final Saga as it moves forward.
