Conqueror’s Haki, also known as the Haki of the Supreme King, is the rarest form of Haki that only a few people in the world of One Piece are born with. Unlike the other two Haki types, Conqueror’s Haki can’t be learned through training and is only possessed by those who are born with the spirit of a king.
Conqueror’s Haki is known to allow a user to assert their willpower over others, knocking out the weaker ones in the process. In addition to this, those who are extremely proficient with the technique are able to coat their attacks with the rare form of Haki, making it one of the most devastating weapons shown in the series thus far.
Post-Wano One Piece Spoilers Ahead!
17 Portgas D. Ace
Arguably no pirate in the New Age was more destined for greatness than Portgas D. Ace. The son of Gol D. Roger first demonstrated Conqueror’s Haki at age 10, and by the time One Piece begins, he also commandeered the powers of the Mera Mera no Mi Devil Fruit.
Unfortunately, Ace’s life came to an end before he mastered either Conqueror’s Haki or his Devil Fruit. While it’s clear that his potential was off the charts, his lack of demonstrable control over the former makes him the series’ least-skilled user.
16 Eustass Kidd
Few characters are capable of rivaling Monkey D. Luffy. Yet, against all odds, Eustass Kid has come very close to doing so. The captain of the Kid Pirates played a major role in the defeat of Kaido and Big Mom, due in no small part to his Conqueror’s spirit.
During his standoff with Kaido, the intimidating Yonko remarked about Kidd’s ability to utilize Conqueror’s Haki, confirming his latent potential. Time will tell if he consciously starts to use the ability to advance his station.
15 Boa Hancock
Also known as the Snake Princess, Boa Hancock is the leader of the Kuja Tribe and one of the strongest characters in the series. As a Queen, it is no surprise to see that she has the power to use Conqueror’s Haki — an ability that is only possible for those with a regal spirit.
The entirety of the Kuja Tribe is known for its tremendous skills with Haki, so it would make sense for Boa Hancock to be an excellent user of its rarest form. While she hasn’t employed Conqueror’s Haki in any on-screen conflict, that seems primed to change in the near future.
14 Chinjao
At one point in time, Chinjao held the rare honor of being considered a rival to both the Hero of the Marines, Monkey D. Garp, and the King of the Pirates, Gol D. Roger. Since his name once carried the same weight as these two legends, it should come as no surprise that the retired pirate wields a devastating power like Conqueror’s Haki.
When fans first meet Chinjao, he is competing in the gladiator tournament for the Mera Mera no Mi. There, he knocks out multiple foes by exerting his will, demonstrating a level of proficiency with Conqueror’s Haki that few One Piece characters have been able to manage.
13 Donquixote Doflamingo
Given Donquixote Doflamingo’s domineering personality, it should come as no surprise that he possesses the rarest form of Haki. As shown during his conflict with the G-5 Marines on Punk Hazard, Doflamingo is capable of purposely using his Conqueror’s Haki to instantly KO his less-threatening opponents.
Doflamingo’s ability to purposefully employ his Conqueror’s Haki demonstrates a level of control that eludes many of the few characters capable of using the rare technique. The villain first awakened this form of Haki when he was only 10 years old, so he’s had plenty of time to familiarize himself with its usage.
12 Charlotte Katakuri

Until the Whole Cake Island arc, fans remained largely in the dark about the mechanics of high-level Haki usage. However, thanks to Monkey D. Luffy’s conflict with Charlotte Katakuri, they are able to see just how devastating these mysterious powers can be.
Katakuri is an expert at utilizing Armament and Observation Haki, and although his mastery over Conqueror’s Haki is far less developed, he is still capable of wielding it on command. As seen when Charlotte Flampe interrupts his fight with Luffy, the Minister of Flour can instantly put weaker opponents to sleep by utilizing this technique.
11 Kozuki Oden
Oden was the Daimyo of the Kuri region of Wano and the rightful heir to the position of Shogun of the land. As a samurai, Oden’s skills — which included the ability to generate Conqueror’s Haki — were beyond anything that the country had ever seen before.
While Kozuki Oden’s Armament Haki was his greatest strength, his conflicts with Whitebeard and Kaido proved that he was more than capable of using Conqueror’s Haki as well. Although he came up short in his battles against both opponents, the scar that he left on Kaido speaks to Oden’s dominating spirit.
10 Yamato
Yamato may not agree with their father, Kaido, and his approach to ruling Wano, but Yamato undoubtedly benefits from his powerful genetics. In addition to their natural strength, Yamato is capable of wielding Conqueror’s Haki — something that they likely owe to the influence of their father.
While running wild on Onigashima as a child, Yamato made a habit out of attacking (and often defeating) Kaido’s subordinates. Through this activity, Yamato awakened their Conqueror’s Haki. After practicing with it for years, Yamato was eventually able to coat their weapon with its devastating energy.
9 Roronoa Zoro
Prior to the Wano arc, Roronoa Zoro’s ability to use Conqueror’s Haki had remained dormant inside his body. However, after Kaido acknowledged the fact that Zoro possessed this skill, he rapidly developed the ability to employ it better than most characters in the series.
During his fight with King, Roronoa Zoro imbued each of his blades with both Armament and Conqueror’s Haki, making him one of the deadliest threats on the entire Grand Line. Considering Zoro’s masterful use of Armament Haki, he should be able to further refine his usage of the ultra-rare ability.
8 Sengoku
Sengoku is the former Fleet Admiral of the Navy and a legend of the bygone era — as a result, he often takes a backseat to One Piece‘s younger generation of characters. He and Monkey D. Garp were the strongest Marines during the era of Gol D. Roger, which can likely be attributed to their masterful use of Haki.
Unfortunately, Sengoku hasn’t gotten many opportunities to showcase his abilities on screen. While he is obviously one of the most powerful characters to have ever appeared in the story, the limits of his Conqueror’s Haki are currently unknown.
7 Big Mom
Charlotte Linlin, also known as Big Mom, is one of the Four Emperors of the Sea and the strongest woman in the world of One Piece. She is the Queen of Tottoland because of her unparalleled strength, and although her Devil Fruit, the Soru Soru no Mi, is a big reason for her might, her usage of Haki is what truly makes her a threat.
As a Haki user, Big Mom is known to be magnificent. Her Conqueror’s Haki is so dense that it can damage the surrounding area, as demonstrated during her clash with Kaido, which split the skies of Wano apart.
6 Silvers Rayleigh
Famed as the Dark King, Silvers Rayleigh is the former First Mate of the Roger Pirates and the Pirate King’s right hand. He’s an exceptionally powerful fighter, and if his reputation along the Grand Line is any indication, then he is also one of the most skilled Conqueror’s Haki users in the entire series.
Rayleigh’s Conqueror’s Haki is said to be over twice as strong as Luffy’s was during the events of the Fish-Man Island arc, meaning that the former Roger Pirate could knock out over 100,000 New World pirates in a single instant. Since Silvers Rayleigh can also imbue his strikes with the Haki, he is easily one of the most impressive characters in the series.
5 Monkey D. Luffy
Monkey D. Luffy is the captain of the Straw Hat Pirates and one of the strongest people in the entire world of One Piece. His ability to use Conqueror’s Haki has been common knowledge since his time on Fish-Man Island, but following his battle with Kaido on Wano, his mastery over the technique has reached all-new heights.
Luffy’s latent potential is as high as anyone in the series, as shown when he used Conqueror’s Haki to knock out many of Kaido’s subordinates while completely unconscious. After learning how to imbue his strikes with the rare form of Haki during his fight with Kaido, the Straw Hat Pirates’ captain officially entered the upper echelon of One Piece‘s strongest characters.
4 Kaido
Also known as the “Strongest Creature in the World,” Kaido is among the strongest characters to ever exist in the world of One Piece. Prior to his defeat at the hands of Monkey D. Luffy, he had a bounty of 4.6 billion Berries — the highest for any active pirate shown within the series.
During the Raid on Onigashima, Kaido showcased the full breadth of his Conqueror’s Haki-related talents. He effortlessly coats his strikes with the technique, making him one of the most devastating threats shown in the entire series. Were it not for Monkey D. Luffy’s reality-altering Devil Fruit, Kaido’s Haki would likely still reign supreme.
3 Whitebeard
Edward Newgate, or Whitebeard, was once the strongest man in the world of One Piece. He was an adept user of all three types of Haki, and as the most powerful of the four Yonko, it goes without saying that he mastered the use of Conqueror’s Haki as well.
Upon clashing with Shanks, his Haki was able to split the skies themselves. What’s more, when he clashed with Gol D. Roger, the power of their Conqueror’s Haki was such that the air itself began to crack and fissure, blowing away everything in their surrounding area.
2 Gol D. Roger
As the King of the Pirates, Gol D. Roger is the strongest pirate to have ever lived in the world of One Piece. Roger had no equal while he roamed the seas, and although Edward Newgate matched him blow-for-blow in combat, the former’s unyielding desire to leave his mark on the world likely made his Conqueror’s Haki second to none.
When Roger’s blade — named “Ace,” an allusion to his only son — met Whitebeard’s in combat, their two weapons were unable to even touch due to the intense aura of Conqueror’s Haki that surrounded them.
1 Shanks
Shanks is the Captain of the Red-Hair Pirates and one of the Four Emperors, just like Big Mom and Kaido. He is an exceptionally powerful fighter and has earned a massive bounty of over 4 billion Berries in an extremely short amount of time — all without the aid of a Devil Fruit.
Shanks is possibly the strongest Conqueror’s Haki user alive in the series. He paralyzed Admiral Ryokugyu, one of the strongest Marines in the entire world, with his Conqueror’s Haki from miles away. In addition to this, the Red-Haired pirate also possesses the ability to counteract Future Sight, an ability made possible by highly advanced Observation Haki, proving that his Conqueror’s Haki is so adept that it can literally negate other characters’ abilities.
