One Piece: 25+ Strongest Haki Users (Ranked)

The One Piece world has seen mysterious powers and abilities from some of our favorite characters. While some gain amazing power from devil fruits, others have learned to harness their own spiritual energy and use Haki in this anime. Every living being in One Piece has Haki, however, only a select few like Roger, Shanks, Garp, and others have managed to master this power. Haki, for those unaware, provides the user with different abilities, including future sight, armor-like protection, and even the ability to overpower others’ will. Based on this, we have curated a list of the strongest haki users in the One Piece anime. Read on to discover each character’s powerful haki and where your favorite character ranks in the list.

Spoiler Warning: This article contains spoilers about the Haki users. We suggest you watch the anime and read the manga first to avoid ruining your experience.

We have already discussed what is Haki and its three types in One Piece in a dedicated article. Read the article to learn about Observation Haki (Kenbunshoku Haki), Armament Haki (Busoshoku Haki), and Conqueror’s Haki (Haoshoku Haki). Each haki type has its own sub-forms and advanced forms as well.

So what all haki types can your favorite One Piece characters use? Find out in this list of the strongest haki users. This list will be updated regularly whenever there is a new addition or power change in the world of One Piece.

1. Gol D. Roger

• Haki they use: Observation, Armament, and Conqueror’s
• Devil Fruit: N/A
• Bounty: 5,564,800,000 Berries

As One Piece fans might have already guessed, the top position belongs to none other than Gol D. Roger, the Pirate King himself. There is a reason why he became the Pirate King and discovered the legendary “One Piece” treasure without devil fruit powers. He did the impossible and rose up to the top while conquering the seas with his supreme Haki powers.

Roger was the epitome of the greatest Haki user as he possessed all three major Hakis known in the world of One Piece. He was the captain of the famous Roger pirates, which consisted of powerful people like Rayleigh, Shanks, Buggy, and many others.

Roger was lauded by all the renowned figures like Kaido, Oden, Garp, and more in One Piece. Even after his death, Roger is still the talk of the town around the world for his powers. Roger used advanced forms of conqueror’s haki as he imbued his sword with conqueror’s haki and clashed with Whitebeard. He also used advanced armament haki for more powerful sword attacks. Additionally, Roger possessed the observation haki, thus, making him the strongest haki user of all time in One Piece.

2. Monkey D. Garp

• Haki they use: Observation and Armament
• Devil Fruit: N/A
• Bounty: N/A

Monkey D. Garp was regarded as the “Hero of the Marines” after the God Valley incident. He is the Monkey D. Dragon’s father and our beloved protagonist Monkey D. Luffy’s grandfather. Garp doesn’t possess any weapon or devil fruit power, but he beat everyone in his way with his “bare fists”. Garp mastered armament haki to such an extent that he earned the title of ‘Garp the Fist.’ He teamed up with Roger and put an end to the formidable Rocks pirate crew, consisting of Rocks D. Xebec, Whitebeard, Big Mom, and more, during the God valley incident.

Garp cornered the pirate king multiple times and Roger mentioned that they both fought to death countless times. Along with Whitebeard and Rocks D. Xebec, Garp also rivaled the pirate king with his haki powers. Garp’s mastery of armament haki was proven when he almost killed Don Chinjao (a great armament haki user who could split an ice continent into two) with a single punch.

In his prime, Garp managed to rival the most powerful pirates in One Piece, and he is still one of the strongest marines even in his old age. He can also utilize observation haki, and it is not confirmed whether he uses conqueror’s haki. We have to wait and see Garp’s powers in action again to learn more.

3. Edward Newgate (Whitebeard)

• Haki they use: Observation, Armament, and Conqueror’s
• Devil Fruit: Gura Gura no Mi (Tremor-Tremor Fruit)
• Bounty: 5,046,000,000 Berries

Edward Newgate, aka Whitebeard, was initially a member of the Rocks pirates but started his own crew later on and became the captain of the Whitebeard Pirates. He was introduced and widely known as the “Strongest Man in the World” in One Piece. Further, Whitebeard ate the Gura Gura no Mi (Tremor-Tremor Fruit), one of the most powerful paramecia-type devil fruits. Before his death, Newgate was one of the four emperors of the sea.

Whitebeard is also one of the few people who could use all three types of haki as well as some of its advanced forms. Whitebeard was seen using advanced conqueror’s haki, with haki infused into his attacks. It was seen in his battle against Roger, where the conquerors clashed against each other. Whitebeard also used armament haki proficiently and imbued it into his weapon during his fight against Oden. Even in his sick state, he dealt damage to Akainu during the Marineford war.

And the one fact that might surprise fans is that Whitebeard could use observation haki even while sleeping. And that’s how he was able to counter Ace’s attack in the past. It’s no wonder that the strongest man in this world is well-versed in all three haki types.

4. Akagami Shanks

• Haki they use: Observation, Armament, and Conqueror’s
• Devil Fruit: Nil
• Bounty: 4,048,900,000 Berries

Akagami Shanks is the captain of the Red Hair Pirates and is one of the four emperors of the sea right now. He used to be a member of the legendary Roger pirates before they parted ways. Shanks is recognized as the master of conqueror’s haki and the killer of observation haki too. He is also one of the few pirates who can use all three types of haki. Shanks has mastered conqueror’s haki and made several members of the Whitebeard pirate crew faint during his visit. Such great use of haki was even lauded by Whitebeard.

In an interview, One Piece creator Eiichiro Oda confirmed Shank’s conqueror’s haki is twice as powerful as Luffy’s. That means Shanks could make over 100,000 people faint with his powers instead of the roughly 50,000 people Luffy knocked down. Even though he was on the outskirts of Wano, Shanks utilized his monstrous conqueror’s haki to stop Admiral Ryokugyu, who immediately froze in place.

All the incidents above prove why Shanks is the master of conqueror’s haki. As seen in his battle with Sakazuki, Shanks can use armament haki to imbue his sword with this power. Shanks can proficiently use observation haki as well, thus, making him one of the strongest haki users in the One Piece anime series.

5. Monkey D. Luffy

• Haki they use: Observation, Armament, and Conqueror’s
• Devil Fruit: Previously known as Gomu Gomu no Mi, but is called Hito Hito no Mi, Model: Nika
• Bounty: 3,000,000,000 Berries

Monkey D. Luffy, the main protagonist, is the captain of the Straw Hat pirates in One Piece and is also one of the four emperors of the sea. Luffy is also one of the very few users who has mastered all three types of haki. He first learned about haki from Silvers Rayleigh after the Marineford war and quickly mastered the basics.

Throughout his battles in the story, Luffy trained and practiced all types of haki and increased his powers gradually. In the Wano arc of One Piece, he learned about the advanced forms of haki, like Ryou, infusion techniques, and others. He leveled up and used everything in his battle against Kaido and emerged as the winner. After the events of the Wano arc, Luffy evolved into one of the strongest pirates in the world.

Luffy is proficiently skilled in observation haki and can foresee the future for a short period of time like Katakuri. He can also use advanced forms of armament haki and conqueror’s haki with ease. Luffy can also combine his haki powers with devil fruit powers, which you see in the form of Luffy’s gears. With the strongest haki powers in his arsenal, Luffy is one of the best haki users in the anime. And there is no doubt that he will climb up the ranks soon.

6. Kozuki Oden

• Haki they use: Observation, Armament, and Conqueror’s
• Devil Fruit: N/A
• Bounty: Unknown

Kozuki Oden was the daimyo of Kuri in Wano country and the leader of the strongest samurais known as the Nine Red Scabbards. Oden is the only person who served as a member of both the legendary Whitebeard pirates and Roger pirates (see One Piece Jolly Roger for popular pirates here). His immense strength was greatly recognized by both Whitebeard and Roger. He lived his life as a great samurai and became a legendary pirate.

Similar to other strong characters, Oden possessed all three types of haki. Oden is a powerful user of armament haki, where he used Ryou combined with his swordsmanship skills. He also used the conqueror’s haki against Beast pirates and used the infusion technique against Kaido and Whitebeard. It is also mentioned that he could use observation haki with ease.

Using his powerful haki techniques, Oden delivered a huge X-shaped blow and gave Kaido the scar on his body. But unfortunately, he lost the battle and had to sacrifice his life. Nevertheless, Oden will always live in the hearts of One Piece fans as one of the greatest haki users.

7. Kaido

• Haki they use: Observation, Armament, and Conqueror’s
• Devil Fruit: Uo Uo no Mi, Model: Seiryu (Fish-Fish Fruit, Model: Azure Dragon)
• Bounty: 4,611,100,000 Berries

Similar to Whitebeard, Kaido was known as the “Strongest creature in the world” and was one of the former emperors of the sea. He led the infamous Beast pirates and was feared by many across the seas. He was also a member of the Rocks pirates along with Whitebeard and Big Mom. Kaido also possessed all three forms of haki and was an experienced haki user.

Kaido can use the infusion technique of conqueror’s haki and armament haki to imbue haki in his weapon. He already possessed immense natural strength but became an unstoppable force by combining it with his haki powers. Kaido also used observation haki to foresee all of Luffy’s attacks in their fierce battle. So yeah, Kaido was an extremely skilled haki user and deserves to be ranked high on this list.

8. Silvers Rayleigh

• Haki they use: Observation, Armament, and Conqueror’s
• Devil Fruit: N/A
• Bounty: Unknown

Popularly known as the “Dark King,” Silvers Rayleigh was the right-hand man of the pirate king Gol D. Roger. He served as the first mate in the legendary Roger pirates. Although Rayleigh has now retired, he is still one of the most important figures in the One Piece world. He also uses all three types of haki and taught the basics of Haki to Luffy, helping him grow into one of the strongest pirates like himself.

Rayleigh is proficient in using conqueror’s haki, as he can concentrate it on any individual he wants. He also employs infusion, an advanced conqueror’s haki technique, to release mighty attacks. Rayleigh showed off his armament haki skills against Kizaru and the wild animals on the Rusukaina Island, where he trained Luffy. Moreover, we saw him use advanced armament haki techniques such as Ryou and Internal destruction even before we got an explanation of these concepts in Wano.

Finally, Rayleigh showed his observation skills numerous times as he explained it to Luffy by fighting an elephant. Thus, Rayleigh makes it into the top 10 on our list of the strongest haki users.

9. Charlotte Linlin (Big Mom)

• Haki they use: Observation, Armament, and Conqueror’s
• Devil Fruit: Soru Soru no Mi (Soul-Soul Fruit)
• Bounty: 4,388,000,000 Berries

Charlotte Linlin, popularly known as Big Mom, was the captain of the Big Mom pirates. She was one of the former emperors and a former member of the Rocks pirates. She was the only female character to become an emperor until now. Big Mom could use all three types of haki, and she was also a highly-skilled haki user like Kaido.

We saw Big Mom use conqueror’s haki during Sanji’s wedding and later she also used the infusion technique when she clashed with Kaido in Onigashima, splitting the skies into two. Big Mom could also use armament haki flawlessly, even Luffy’s Kong gun did not work against her hardened body back then. It was also mentioned that she was an observation haki user. Her haki was mentioned as too strong by Law during their battle on the rooftops of Onigashima. Thus, she takes the 8th position in our list of strongest haki users.

10. Dracule Mihawk

• Haki they use: Observation and Armament
• Devil Fruit: N/A
• Bounty: 3,590,000,000 Berries

Dracule Mihwak is widely known as the “Strongest Swordsman in the world” and that automatically cements his place among the strongest pirates in the world. He defeated all the enemies in his way and earned the title of the greatest swordsman, beating our beloved Zoro. He is also the main rival of the emperor Shanks, indicating the immense strength he possesses. Mihawk’s swordsmanship skills are said to be higher than that of Shanks, even though he can only use two haki types, which are observation and armament haki.

Mihawk got his epithet “Hawk Eyes” due to his great eyesight, making full use of his observation haki. He can also combine his armament haki with his swordsmanship and employ his “Black Blade Yoru” technique against enemies. Moreover, he taught Zoro about haki, proving his experience and worth as a highly-skilled haki user.

11. Sengoku

• Haki they use: Observation, Armament, and Conqueror’s
• Devil Fruit: Hito Hito no Mi, Model: Daibutsu (Human-Human Fruit, Model: Buddha)
• Bounty: N/A

Sengoku, widely known as “Sengoku the Buddha,” was the former fleet admiral of the marines before Sakazuki and was highly regarded by Roger. He is a powerful marine and an important figure like Garp in the One Piece universe. He has the ability to use all three types of haki and is the only person in the Marine who can do that.

Sengoku possesses some extreme powers, but we have not seen him use any of his powers until now. Thus, he certainly belongs in this list of strongest haki users, and we hope to see his haki powers in action soon.

12. Kizaru, Akainu, and Aokiji

• Haki they use: Observation and Armament
• Devil Fruit: Pika Pika no Mi | Magu Magu no Mi | Hie Hie no Mi
• Bounty: N/A

Everybody knows that one needs to master Haki to become a Vice Admiral or Admiral in the Marines in One Piece. The higher the position, the superior the mastery of haki they hold. With that said, the three supreme forces of Marines when combined together were totally scarier back at the Marineford Arc (although they have gone in different paths now). Previously, these three admirals trio showcased their brilliant mastery of Haki against Whitebeard.

Though they can use only two types of haki (Observation and Armament Haki), and we haven’t seen them use them in action many times, we can say that they possess devastating Haki abilities in the palm of their hands. It’s a no-brainer that the greatest powers of Marines will have a greater haki power for sure.

13. Fujitora

• Haki they use: Observation and Armament
• Devil Fruit: Zushi Zushi no Mi (Press-Press Fruit)
• Bounty: N/A

Issho, popularly known as Fujitora, is one of the admirals of the marines. Along with Ryokugyu, he is mentioned as a powerful monster in the Marines by Doflamingo. One should note that he earned this title despite being completely blind. That tells a lot about the Observation haki skills he possesses. Like a few other admirals, Fujitora can also use observation and armament haki. He can combine his magnificent haki skills with his swordsmanship and devil fruit powers, making makes him a big deal in the One Piece world.

Although he is blind, Fujitora has mastered Observation Haki to see the world with the powers of haki. He can sense the presence of people around him and sense any incoming danger precisely. By using this type of haki, he overcomes the weakness that comes with his blindness. Also, Fujitora can sense other people’s emotions like Luffy and Princess Otohime, as demonstrated at the end of the Dressrosa arc. Fujitora is also extremely skilled at using armament haki, as he was seen imbuing his sword Shikomizue with haki in his battle against Sabo.

14. Charlotte Katakuri

• Haki they use: Observation, Armament, and Conqueror’s
• Devil Fruit: Mochi Mochi no Mi (Mochi-Mochi Fruit)
• Bounty: 1,057,000,000 Berries

Charlotte Katakuri is one of the sons of Big Mom and is also one of three sweet commanders of the Big Mom pirates. He is known to be the strongest pirate in Big Mom’s crew and went undefeated until he met Luffy. Just like his mother, he possesses all three types of haki.

Katakuri awakened his conqueror’s haki when saving his sister, and we saw it in action during his battle with Luffy. He is also extremely skilled in armament haki as he combined his devil fruit powers with his haki powers and created more powerful attacks. But Katakuri’s most powerful haki has to be his observation haki. He can foresee the future for a short time during a fight and predict surprise attacks, as seen in the Whole Cake Island arc. Katakuri belongs on this list for his superior observation haki abilities.

15. Roronoa Zoro

• Haki they use: Observation, Armament, and Conqueror’s
• Devil Fruit: N/A
• Bounty: 1,111,000,000 Berries

Roronoa Zoro was previously known as the “Pirate Hunter Zoro” as he was a bounty hunter before meeting Luffy and joining the Straw Hat pirates. He is the right hand of the future pirate king Luffy and a loyal member of his pirate crew. Like his captain, Zoro is also proficient in all three types of haki, as per recent revelations. Using his three-sword style and sword collection, Zoro aims to beat Dracule Mihawk and become the strongest swordsman in the world.

As for his haki abilities, Mihawk was the one who taught Zoro about haki. He then used observation haki to detect a wild beast on Fishman island and confirmed its existence. He was also seen using armament haki by imbuing his swords with haki against Monet in Punk Hazard and started using it frequently in the future.

Zoro awakened his dormant conqueror’s haki power in the Wano arc, where he used his Nine Sword-style attacks against Kaido. Later, he learned to use the infusion technique to coat his three swords to increase their attack power against King. Zoro is also one of the upcoming and talented haki users, who will jump up the list in no time.

16. Marshall D. Teach (Blackbeard)

• Haki they use: Observation and Armament
• Devil Fruit: Yami Yami no Mi (Dark-Dark Fruit) and Gura Gura no Mi (Tremor-Tremor Fruit)
• Bounty: 3,996,000,000 Berries

Popularly known as Blackbeard, Marshall D. Teach is the captain of the notorious Blackbeard pirates and is one of the four emperors of the Sea alongside Shanks, Luffy, and Buggy. He is the only person to possess two devil fruit powers in the entire One Piece world. He is already scary enough without accounting for his haki powers, isn’t he?

Well, Blackbeard can use observation haki and armament haki, making him one of the most powerful pirates in the world right now. He showed his armament haki techniques by hardening his body parts in the recent manga chapters against Seraphim (New Pacifista). He can also use observation haki as he sensed Luffy’s increased power levels during his raid on Impel Down. New updates about Blackbeard’s haki powers have started to show up in recent manga chapters, and we will see more of his powers sooner for sure. For now, he remains in the 12th position due to the unknown possibilities of his haki abilities.

17. Donquixote Doflamingo

• Haki they use: Observation, Armament, and Conqueror’s
• Devil Fruit: Ito Ito no Mi (String-String Fruit)
• Bounty: 340,000,000 Berries

Donquixote Doflamingo was a former celestial dragon and went on to become the infamous broker of the underworld with the codename “Joker”. He was also previously regarded as one of the seven warlords of the sea. Right now, he is the captain of the Donquixote pirates in One Piece. Doffy is one of the most loved antagonists in the anime series, and that’s all because of his pure evilness, ideals, and dialogues. He is also one of the strongest haki users who can use all three types of Haki.

Doflamingo awakened his conqueror’s haki when he was 10 years old and was chased by the people who wanted to hurt his family. Later in Punk Hazard, he was again seen using conqueror’s haki to knock down the marines. He can also use observation haki, and his armament haki skills are a lot better too. Doflamingo hardened his body during his battle with Luffy, reduced all incoming damage, and even sent Luffy flying afterward. He is currently a prisoner, but let’s hope he gets out to treat us with his excellent powers in the future. He remains in the 18th position on our list of strongest haki users for now.

18. Yamato

• Haki they use: Observation, Armament, and Conqueror’s
• Devil Fruit: Inu Inu no Mi, Model: Okuchi no Makami (Dog-Dog Fruit, Model: Okuchi-no-Makami)
• Bounty: Unknown

Yamato is the daughter of Kaido, and her addition to this list might come as a surprise to some. Kaido aimed to make Yamato his heir, but she expressed her admiration for Oden by announcing herself as Oden after his death. Hence, she started identifying herself as Kaido’s son and started impersonating Kozuki Oden. Like her dad, she also has all three types of haki at her disposal.

Yamato awakened her conqueror’s haki when she was just a kid. Now, she is capable of even performing the infusion technique, which she imbues on her weapon. She can perform powerful attacks like Raimei Hakke and Shinsoku Hakujaku with this technique. Yamato can also perform observation haki, but we haven’t seen her use any advanced forms yet.

Yamato used armament haki in her fight against Ace when he visited Wano to bypass the logia’s impalpable body. Yamato’s strength was proved in the Wano arc, and we hope she will join the Straw Hat pirates in the future. Thus, we rank her in the 18th position for now.

19. Trafalgar Law

• Haki they use: Observation and Armament
• Devil Fruit: Ope Ope no Mi
• Bounty: 3,000,000,000 Berries

Trafalgar D. Water Law is the captain of the Hearts Pirates and is one of the most popular characters in One Piece. He is also known as the “Surgeon of Death” for his devil fruit powers. He also belongs to the group of Worst Generation Pirates like Luffy, Kid, and Zoro. Although we hardly witnessed Law use Haki in the anime, he’s starting to demonstrate his powers in his fight against Blackbeard in the recent manga chapters.

Law can use Armament and Observation Haki with ease. Currently, it is unknown at the moment if he can perform advanced forms of haki. But, after his clash with the two ex-emperors of the sea, he learned that “the devil fruit powers can be countered if you use a great deal of Haki.”

Right now, he is toe-to-toe with the mighty Emperor Blackbeard with his haki and devil fruit powers combined. Law has been shown using his armament haki against Vergo and other highly skilled haki moves. He can also perform Observation haki, and it was seen recently when he was able to sense the defeat and awakening of Luffy. Therefore, Law is starting to rise in our list of strongest haki users.

20. Jinbe

• Haki they use: Observation and Armament
• Devil Fruit: N/A
• Bounty: 1,100,000,000 Berries

Jinbe is the latest addition to the Straw Hat Pirates and is the Helmsman of the crew. He is famously known as the Knight of the Sea and is a formidable master when it comes to Fish-Man Karate. He was a member of the Sun Pirates and became their second captain. But he has now joined the Straw Hats to help Luffy become the Pirate King. Jinbe can use the Armament and Observation Haki.

As a great veteran pirate, Jinbe has a great experience and knowledge about battles. He can perform his mighty Fish-Man Karate moves along with his Haki powers. For example, his Kairagi move. Recently, he showcased his Armament Haki abilities against Who’s Who, who is a proficient user of Armament Haki himself. Jinbe was able to sense Shanks’ Conqueror’s Haki, confirming his Observation Haki ability.

21. Sanji

• Haki they use: Observation and Armament
• Devil Fruit: N/A
• Bounty: 1,032,000,000 Berries

Vinsmoke Sanji is the cook of the Straw Hat Pirates and the left-hand man of the future Pirate King Monkey D. Luffy (read the significance of D in Luffy’s name here). He is popularly known as Blackleg Sanji for his usage of his fiery legs in the battle. His cybernetic enhancements were awakened during the Raid on Onigashima, and he has become much stronger since. Sanji can use the two forms of Haki — Armament, and Observation.

Sanji heavily relies on his legs and uses his own Blackleg style in his battle. He was previously using “Diable Jambe” attacks, but during the Raid on Onigashima, he combined it with his Armament Haki to produce a more red-hot powerful attack known as “Ifrit Jambe,” which helped him beat Queen of the Beast Pirates. Sanji is also an extremely skilled user of Observation Haki in One Piece as he was seen people’s emotion and their presence in Fishman, Dressrosa, and Whole Cake Island Arcs.

22. Boa Hancock

• Haki they use: Observation, Armament, and Conqueror’s
• Devil Fruit: Mero Mero no Mi (Love-Love Fruit)
• Bounty: 1,659,000,000 Berries

Last but not least, we have Boa Hancock on our list of the most powerful haki users in One Piece. She is widely regarded as the “Pirate Empress” and is the captain of the Kuja Pirates. Currently, she is the Snake Princess of Amazon Lily Island, but she used to be one of the seven warlords of the sea before the world government took down the organization. She remains one of Luffy’s powerful allies and is also in love with him. She also possesses all three types of haki and is the only female character to become a warlord.

Boa Hancock’s haki powers are yet to be showcased in both the manga and the anime. But the powers have been confirmed already in the One Piece databook. We have already seen how powerful she is in the Marineford war, and hopefully, she will reunite with Luffy and show off her true powers again.

23. Eustass Captain Kid

• Haki they use: Observation, Armament, and Conqueror’s
• Devil Fruit: Jiki Jiki no Mi (Magnet-Magnet Fruit)
• Bounty: 3,000,000,000 Berries

Eustass Captain Kid is the captain of the Kid pirates and belongs to the Worst Generation of pirates alongside Luffy, Law, and nine others. He is a brave and fearsome pirate who even went on to challenge Shanks, one of the emperors of the sea. Kid’s powers started to increase gradually as he trained and developed his abilities over time. He is also among the few individuals who can use all three forms of haki.

Kid’s armament and conqueror’s haki powers haven’t been shown in the manga but it was confirmed that he has it by Kaido. But he used observation haki to sense Luffy’s defeat against Kaido and even found out that Luffy had awakened his devil fruit powers later on. Like a few other characters on this list, we hope to see Kid’s ultimate haki powers in the near future.

24. King

• Haki they use: Observation and Armament
• Devil Fruit: Ryu Ryu no Mi, Model: Pteranodon
• Bounty: 1,390,000,000 Berries

King is the right-hand man of Kaido and is one of the three members of the All-Stars of Beast Pirates. His real name is Alber, but he went on to earn the title of King the Conflagration. He is a descendant of the Lunarian race of the Red Line. Hence, he has wings and can create fire at his will. King’s hefty bounty directly indicated how powerful he is and no wonder he is the right-hand man of the legend Kaido.

King possesses the ability to use both the Armament and Observation Haki. However, he is regarded as a highly skillful user of Armament Haki as he can harden his sword, imbuing it with haki. We haven’t seen his Observation Haki powers, but he is confirmed to possess them. Therefore, King is currently ranked 24th in our list of strongest Haki users.

25. Benn Beckman

• Haki they use: Observation and Armament
• Devil Fruit: N/A
• Bounty: N/A

Benn Beckman is the loyal right-hand man of the Legendary Shanks. Just like how Zoro is a loyal first mate of Luffy, Ben is the same to Red hair Shanks. He is known to have the highest IQ of any character in the East Blue Saga. It is unconfirmed whether he has any devil fruit or not, but he is confirmed to have Armament Haki for the moment.

As the right-hand man of Shanks, we can’t underestimate Ben, he is certainly one of the powerful characters in One Piece, though, we have seen only little of him. Just as a swordsman imbues armament haki in the sword to harden it, Ben imbues haki into his rifle’s bullets. That is a well thought technique, and he was able to hold freaking Kizaru at gunpoint in the Marineford arc. Due to the unknown nature of his haki powers, he is currently ranked in the last position.

26. Rocks D. Xebec

• Haki they use: N/A
• Devil Fruit: N/A
• Bounty: N/A

Rocks D. Xebec is an important figure in the One Piece world. He was the captain of the Rocks Pirates, which had Whitebeard, Big Mom, Kaido, Shiki, and several other amazing pirates as its members. He had three ex-emperors of the seas as his crewmates previously, which tells us much about his power levels. Although nothing is known about this man at the moment, we certainly believe he can top our list of strongest Haki users once more information is revealed.

It took Roger and Garp’s powers combined to beat this man in the God Valley Incident. He was one hella scary pirate back in the day, and we can’t wait to see more of him soon.

27. Monkey D. Dragon

• Haki they use: N/A
• Devil Fruit: N/A
• Bounty: N/A

Monkey D. Dragon is the father of Monkey D. Luffy and the son of Marine Hero Garp. He is infamously known as the “Rebellious Dragon” and is regarded as the most wanted criminal in the whole world of One Piece. He is the supreme commander of the rebellious Revolutionary Army and one of its founding members.

One Piece world’s greatest power that is the World Government is chasing him, and we are sure that he possesses stronger combat abilities than Haki. Many fans predict that Monkey D Dragon will be confirmed to have Conqueror’s Haki like his son in the future. Like father, like son, right? Monkey D. Dragon can storm his way to the top half of this list once his powers are revealed.

So that’s all for our list of strongest haki users in the One Piece anime. We hope we were able to distinguish each and every character’s haki powers and suitably explain them to you fans out there. We have made this list based on all the current information sources, but we hope to see Luffy and Zoro move up the list as the story progresses. As new information about haki types and their users is revealed in the anime or manga, we will make sure to update this list regularly. In the meantime, let us know if you think we have missed out on any characters that should belong on this list. Also, who is your favorite haki user in the One Piece world? Do let us know in the comments section.
