In terms of ranking criteria for this list, we’ll be considering not only the strength and effectiveness of each character’s Conqueror’s Haki, but also their overall power level throughout the series.
Without further ado, let’s dive into our list of the top 10 most powerful Conqueror’s haki users in One Piece!
Reminder about Conqueror’s Haki
Conqueror’s Haki, also known as Haōshoku Haki, is a rare form of Haki that only the strongest individuals possess.
The power is so intense that it can influence the weak-willed and knock out anyone in the vicinity. Only those with immense strength and mental fortitude, such as Kaido or Gol D. Roger can possess Conqueror’s Haki, which emanates from their spirit and willpower.
With the ever-increasing number of characters in One Piece, there are many potential Conqueror’s Haki users. However, the next users to make it into the top 10 rankings will have to possess exceptional strength and leadership qualities to showcase their Conqueror’s Haki skills.
Criteria for selection of Conqueror’s Haki users
In determining the top ten most powerful Conqueror’s Haki users, we have ranked them based on their feats in the anime and the strength of their Haki.
We’ve also considered the magnitude of the impact they’ve had in the One Piece world.
10Donquixote Doflamingo
Donquixote Doflamingo, also known as the “Heavenly Yaksha,” is one of the most notable villains in the One Piece universe. As a Shichibukai and former World Noble, he was a major player in the underground world of pirates and mercenaries. But what sets him apart from his contemporaries are his formidable Conqueror’s Haki abilities.
From his younger ages, the “Celestial Dragon” displayed his latent talent for Conqueror’s Haki, as he was about to be burnt alive, along with his family.
Later on, Doffy attested his mastery of Haki to knock out swarms of Marine soldiers, or even to enhance his strikes.
In addition, his blind overconfidence fuels his willpower as a fighter, and perfectly portrays his Puppet Master’s mindset.
9Roronoa Zoro

Roronoa Zoro, the swordsman of the Straw Hat Pirates, also possesses the rare and powerful ability that the Conqueror’s Haki is.
Zoro’s Conqueror’s Haki hasn’t been fully displayed before the exhilarating Wano Country arc. In this arc, Zoro awakened the Conqueror’s Haki imbuement with on his katanas to bleed Kaido himself.
The latter acknowledge this value of his Haki, in some stunning scene.
8Monkey D.Luffy
Monkey D. Luffy is one of the few powerful users of Conqueror’s Haki and deserves his place in the top 10 list. From a young pirate with no knowledge of Haki to one of the strongest beings in the New World, Luffy has come a long way.
After awakening this skill in the pre-time skip events, and sharpening it during the two-years pause, Luffy became a skilled Conqueror’s Haki master.
We got palpable proof of this statement during his clashes against Doffy at Dressrosa, Katakuri at Whole Cake Island, and more recently at Wano against the Yonko Kaido.
It is also confirmed that Luffy reached the formidable level of Golden Haki. Kaido himself was heavily impressed by Luffy’s feats.
7Yamato
Yamato is one of the most powerful characters in One Piece and has been a fan-favorite since his introduction.
Many fans have wondered, does Yamato have Conqueror’s Haki?
The answer is an overwhelming yes! Yamato was capable to put out of action some of his father’s warrior with absolute ease. He/She can also use it to create immense physical strength, allowing him to overpower opponents without their knowing.
Additionally, during his fight against Kaido, he used this power to support Luffy in a stunning animation in the anime. Given these feats, it seems clear that Yamato is among those who possess the strongest levels of Conqueror’s Haki in the entire world of One Piece.
6 Monkey D. Garp
Monkey D. Garp is known for his incredible strength, speed, and fighting skills, as well as his mastery of the Conqueror’s Haki.
Garp’s Conqueror’s Haki is so strong that he can knock out thousands of weak-willed individuals with a single shout, and even cause physical damage to his surroundings. He has also been known to use his Haki to intimidate and deter opponents, making him a formidable opponent in battle.
What sets Garp apart from other Conqueror’s Haki users is his unique perspective on the ability. As a Marine, Garp believes that Conqueror’s Haki is not just a tool for intimidating and defeating opponents, but a responsibility that comes with great power.
He sees it as his duty to use his Haki to protect others and maintain order in the world of One Piece, rather than to conquer and dominate. Surely why he refused the Admiral rank.
One of the most impressive feats of Monkey D. Garp involving Conqueror’s Haki was his recent Galaxy Impact against Blackbeard.
It cemented Garp’s status as one of the most powerful and respected characters in the series, and showcased the true potential of Conqueror’s Haki in the hands of a skilled user.
5Big Mom

Charlotte Linlin, better known as Big Mom, is a pirate and one of the Yonko who rule over the New World.
Big Mom is considered among the strongest users of Conqueror’s Haki, on par with Kaido’s. With this power, she can knock out weakling opponents simply by staring at them or intimidate multiple people at once using only her presence.
Her overpowered Devil Fruit abilities, coupled with her Conqueror’s Haki mastery, and her hunger crisis make her a force to be reckoned with.
It is clear that Big Mom should be placed high up on any ranking list for powerful Conquerors Haki users. In comparison to other characters like Katakuri and Mihawk whose abilities are similar to hers, it is safe to say that Big Mom stands head and shoulders above the aforementioned Haki users.
4Kaido

Kaido’s power puts him high up on any ranking of conquerors haki users but there are still several contenders that remain ahead of him. In the recent events, he clashes with Yamato who was trying to stop him from killing Momonosuke.
With such immense power at her disposal it’s no wonder why he ranks so highly among conquerors haki users worldwide.

Shanks is an influential figure in the world of One Piece, renowned for his great strength and commanding presence. He has been shown to possess all three forms of Haki: Busoshoku (Armament), Kenbunshoku (Observation) and Conqueror’s Haki making him one of just a few characters who can use each type.
Shanks was also seen using his Conqueror’s Haki to knock out foes, just as he did when he paid a visit to Whitebeard and his crew.
Recently, Shanks managed to immobilize the admiral Ryokugyu from miles away from Wano. This alone speaks volumes about how much skill and control he has over it. Shanks stands out amongst all conqueror haki users due to the uniqueness of his Conqueror’s Haki.
His influence stretches far beyond what we have already seen from him, which makes him both feared and respected by others who have encountered him – or simply heard tales about him!
2Whitebeard

Widely known as ‘The Strongest Man in the World’, Whitebeard was one of the most powerful pirates to ever set sail. His fame and strength came from his legendary Conqueror’s Haki, an ability that only a select few could master.

His legacy continues to live on through those of his crew and anyone else who has mastered this difficult skill. Even after death, Whitebeard remains an inspiration for all those who can use Conquerors Haki – proving that no matter what life throws at you, never give up hope!

His mastery over Conqueror’s Haki is well-known throughout the world; even after his death, it seemed like no other pirate would ever match up to him.
His use of Conqueror’s Haki allowed him to become akin to a legend amongst those who sailed the Grand Line.
