Zoro and Sanji’s rivalry in One Piece is a tale as old as time. The duo have engaged in so many petty quarrels that even their fans have become divided now. Every other day, you will discover a new trending post on why one of them is superior to the other.


Lately, Zoro’s power-ups have given One Piece fans a chance to drag down Sanji. This is especially influenced by the fact that Eiichiro Oda provided Zoro with Haoshoku Haki or Conqueror’s Haki, while Sanji is still relying on kicking as hard as possible.

The Secret Behind Conqueror’s Haki in One Piece

Conqueror’s Haki is famous for being the rarest type of Haki. While the other two types can be gained through training and willpower, the same cannot be said about Conqueror’s Haki. Only one in a million people are born with this ability.


Some of its current users include Zoro, Luffy, Hancock, Rayleigh, Sengoku, and more. Those who possess this Haki are considered Supreme Rulers and are highly coveted people. Now that the series is reaching its end, only the strongest are left and will engage in a historic clash.

A One Piece theory suggests that Conqueror’s Haki could be acquired just like the others, but to gain it, one must lose the fear of death. Blackbeard, being a coward, might not be able to access it. It makes little sense that two Hakis could be unlocked, but another one is only randomly distributed by birth.

There is a possibility that Conqueror’s Haki can also be unlocked but the necessary conditions are harder to meet. One might be able to unlock the power by conquering the fear of death. The individuals who have this Haki are fearless people who have won countless battles. Maybe for those who are slightly weaker, different circumstances forced them to overcome death’s fear, but they never realized it.


Sanji Might Activate Conqueror’s Haki

Zoro was not able to activate Conqueror’s Haki till his battle with Kaidou. During the battle, he was exhausted, pushed near death, and was still recovering from the previous fights. Yet, with everything he had left, Zoro attacked Kaidou with Ashura Bakkei: Moja no Tawamure.

Kaidou was shocked to notice that Zoro had unknowingly infused Haoshoku Haki when he struck the Emperor. As usual, Zoro was disappointed for not finishing the task, but Kaidou commended him for being able to scar him. Kaidou defeated Zoro soon after, but the discovery was already done. After the battle, Zoro slowly sharpened his new weapon for further use. A similar experience is likely to trigger the ability in another person.

If the previous theory is to be followed, it would mean that Sanji just hasn’t reached a stage where he is no longer afraid of death. Maybe in a future battle, he will have a near-death experience just like Zoro. Thus, it would enable him to activate Conqueror’s Haki.

The upcoming battles in One Piece will be the most fierce ones you have ever seen and Sanji will have plenty of enemies to fight. One of them could prove to be his ultimate nemesis, worthy enough to activate his Haki.

In fact, Sanji might be able to activate an advanced version of Conqueror’s Haki in order to not only match Zoro, but also overtake him.
