In fact, by specializing in a certain type of Haki, one can attain strength enough to reach the highest of levels in the world ofOne Piece, as shown by many fighters over the years.
Updated Jul 18, 2025 by Rei Penber: Haki is an incredible ability in the One Piece world that is continually gaining importance as the story moves forward. Although Devil Fruits hold tremendous importance and are, arguably, the main power system in the series, Haki is what conquers all and truly makes one stand out. This list already includes the ten best Haki specialists in the One Piece world, however, with the ongoing Wano Country arc, fans have witnessed some new specialists pop up, and with that in mind, we’ve updated the list.
14Sentomaru
Sentomaru is a high-ranking member of the Marines and he joined their ranks officially during the timeskip. On Sabaody Archipelago, Sentomaru showed his incredible skill with Haki and made it known that he is, in fact, a specialist at using Ryuo.
According to him, he has the tightest defense in the entire world, meaninghis Haki is quite powerful. While the full extent of his powers hasn’t been seen yet, fans will surely see what he is fully capable of doing when he returns.
13Sanji
Sanji is the cook of the Straw Hat Pirates and also a member of the Monster Trio, making him one of the most dangerous people on the seas in the whole world. During the Wano Country arc, fans saw Sanji gain several new powers, such as his exoskeleton, that allowed him to easily overpower Queen the Plague, one of Kaido’s right-hand men.

However,Sanji’s true skill lies in his Observation Haki, which is extremely impressive. Even though Luffy can see the future, he has openly admitted to his Haki being inferior to Sanji in some aspects, which just goes to show how great a user of this ability he is.
12Charlotte Katakuri
The strongest of the Three Sweet Commanders of the Big Mom Pirates, Katakuri isa man worth 1.057 billion berries, which is a huge figure. Although he wields the power of the Special Paramecia type Mochi Mochi no Mi, Katakuri’s real skill lies somewhere else.
Over the years, he has trained his Observation Haki to sky-high levels. By breaking all his limits, he gained the ability to look several seconds into the future, making him the best specialist of Observation Haki in the story so far.
11Roronoa Zoro
One of the strongest characters in the Straw Hat crew, Zoro is an incredibly skilled swordsman who heavily relies on the usage of Haki in combat. In the Wano Country arc, Zoro received Enma, one of Oden’s swords, which allowed him to bring out his strongest Haki forms.
Along with high-level Armament Haki, Zoro was also able to use Conqueror’s Haki to coat his blades in combat. Although Zoro can only use these abilities unregulated for a few minutes, he’s an extremely skilled user of both and is one of the strongest Haki users in the series currently.
10Yamato
Kaido’s son, Yamato has inherited his father’s incredible conqueror’s spirit and has the ability to use high-level Haki as well. Although his Observation Haki skills haven’t been seen so far, Yamato has used the advanced forms of both Armament and Conqueror’s Haki.
Yamato’s strongest skill is certainly his Conqueror’s Haki, which he can channel into his club while fighting. Using this power of his, Yamato was able to fight Kaido on an even footing for a while and even inflict injuries upon him. Without a doubt, Yamato is a specialist in Haki.
9Dracule Mihawk
Mihawk is the strongest swordsman in the world ofOne Pieceand it goes without saying that he’s among the top tiers of the verse. He wields the Saijo o Wazamono grade sword called Yoru, which is also a black blade, thanks to the constant imbuement of Haki into it.
Given that Mihawk is far more skilled than the likes of Zoro and that he doesn’t have a Devil Fruit ability, he is an exceptionally skilled user of Haki. Mihawk is, more likely than not, a user of the advanced forms of both Armament and Conqueror’s Haki.
8Silvers Rayleigh
The former right-hand man of the Pirate King, Silvers Rayleigh stillranks among the most ferocious peoplein theOne Pieceworld. In fact, his bounty is still active despite having left piracy years ago. Rayleigh’s strength is considered to be legendary in theOne Pieceworld.
Yet, he doesn’t possess any Devil Fruit power. It is quite evident that his biggest strength is his control over Haki. Rayleigh seems to specialize in the usage of Armament Haki, as seen when he destroyed Camie’s explosive collar on Sabaody Archipelago.
7Monkey D. Garp
The Hero of the Marines, Garp is another legend in the world ofOne Piece. He is known to be the strongest Marine to ever live and is the only one in their ranks, along with Sengoku, who is capable of rivaling the likes of Gol D. Roger and Whitebeard.

Garp doesn’t possess any Devil Fruit power, but he does have access to Haki. It seems that he specializes in the usage of Armament Haki as that’s what he used to crush 8 mountains and, later, to flatten Don Chinjao’s head.
6Boa Hancock
Renowned as the Pirate Empress, Boa Hancock is one of the most powerful characters in theOne Pieceworld. She possesses the powers of the Paramecia type Devil Fruit called Mero Mero no Mi, however, her true skill lies in the usage of Haki.
The Kuja, in general, are considered to be a tribe of Haki specialists. Hancock,being a user of Conqueror’s Haki, is likely a specialist of this power. Her true skill in combat hasn’t been shown yet, however, she is one of the very few people in the world whose strength is acknowledged by many.
5Kaido/Big Mom
Both Kaido and Big Mom are members of the Four Emperors of the Sea and are fearsome pirates, having the highest and the second-highest active bounties in the story, respectively. While both of them possess Devil Fruit powers, they are also highly skilled in the usage of Haki.
Kaido, in particular, makes use of Conqueror’s Haki in almost every attack of his, implying he is a specialist of this power. Similarly, Big Mom can alsomake use of advanced Conqueror’s Haki, however, she tends to use it less often.
