In the One Piece series,haki is a power systemthat separates the strong from the weak. It is not just about haki only because it is the ultimate measure of the characters’ willpower and dominance during battle.
One Piece: 8 Characters Who Deserve More Screen Time In The Final Saga
The final saga of One Piece is here, but some characters must get more screen time to fulfill their roles before the story reaches the endgame.
However, only a handful of characters in the series have mastered the control of haki to its utmost extent. This ranking is not just about strength but about those who pushed haki to its limit. These are the most incredible haki users in One Piece, showing that this power system has made them stand above the rest.

10Charlotte Kantakuri
The Strongest Sweet Commander
The son of Big Mom perfected his haki to an extreme level. In the battle against Luffy in the mirror world on Whole Cake Island, we saw the extreme level of his observation haki.
Kantakuri refined his haki to the extent that he ensured that even his enemies never had a chance to touch him. Kantakuri might not have the world-breaking power of someone like Shanks or Kaido, but his excellent observation haki mastery, which can see into the future, put him above some other users in the series.

He can also use other forms of haki, including conquerors, which means he was also born with the potential to rule and a strong will.
9Charlotte Linlin (Big Mom)
The Iron Lady Of Totto Land
Whether you love or hate Big Mom, you can’t deny that she is one of the most terrifying forces in the series. While her monstrous size is enough to make any enemy think twice about confronting her, her mastery of haki also sets her apart.
She can coat her attacks with haki, which always amplifies each strike with more brutality and force. Armaments haki make our body nearly impenetrable that even law and kid had to push their abilities to the limit to take her down in Wano.

WhileBig Mom mastery of hakiis excellent, she could not achieve the same level of finesse and efficiency as Roger, nor was she ever on par with the pirate king like Whitebeard. However, she’s still a monster who became an emperor.
The King Of The Beast Pirates
Kaido mastered all three types of haki and fought against Luffy, Zoro, and many top-tier fighters duringthe Onigashima raid in Wano. He is the strongest creature in the world, but his downfall comes from the overconfidence in his powers.
He had future sight and advanced armament haki, yet Luffy, Zoro, and Oden could still hurt him. Even his conqueror’s haki was not enough to keep him on top.

However, his position as the strongest in the world and someone Doflamingo fears should not be taken lightly. After all, Kaido was defeated by fate and a manifestation of a mythical power bigger than him.
7Edward Newgate (Whitebeard)
The Last Figure Of The Old Era
At his peak, Whitebeard’s haki was terrifying, and the only reason he was not ranked higher was that age had taken its toll. The Whitebeard we saw at Marineford was a dying man, but the man stood up to Roger as an equal in his prime, which means he could have easily been in the top four if he died duringthe old era.

The Gura Gura no mi devil fruit also made him rely more on the destructive abilities of his fruit rather than pushing his haki to the extreme. He maintained dominance for decades, and no one dared challenge him despite his illness.

6Monkey D. Garp
The Legendary Hero Of The Marine
Garp is almost purely an armament haki specialist, but his mastery of it is so powerful that it puts him in the top five. The hero of the navy is a title given to Garp alone in the Marine, and he achieved that through haki alone.
At God Valley, Garp fought against Rocks D. Xebec’s pirate crew, which had Rocks, Whitebeard, Kaido, Big Mom, and others without a devil fruit. Even at 78 years old, Garp walked into Hachinosu and fought Blackbeard’s commanders at once, and they were terrified of him.
He unleashed the Galaxy Impact on Hachinosu and flattened the entire city from a distance without making any contact. If Aokiji hadn’t been there, he might have wiped out the entire Emperor’s crew.
5Monkey D. Luffy
The Future Pirate King
Luffy being number four might seem low for someone who defeated Kaido and awakened as the god of liberation, but the reality is thatLuffy is still growing. Luffy’s placement is not about weakness because he is already one of the greatest haki users in history; however, his abilities are still progressing and reaching a top-tier level.
Luffy has advanced mastery of all three forms of haki, which is something few characters in the series have accomplished. His haki growth post-time skip has shown in fights against Donquixote Doflamingo, Charlotte Kantakuri, and particularly Kaido.
Currently, Luffy stands just below Joyboy, Roger, the five elders, and Shanks, but he is already a legendary Haki user and hasn’t reached his limit. This means the day might come when Luffy’s haki will surpass them all.
The Man Who Humbled Eustass Kid
Red-haired Shanks is the only emperor of the sea who relies solely on haki and has no devil fruit. The mere fact thathe rose to emperor statuswithout a devil fruit proves just how strong he is, just like his ex-captain, Roger.
Shanks hasn’t gotten much screen time in the series, but his power level has been shown a few times. The emperor’s conqueror’s haki was demonstrated during one of his meetings with Whitebeard on Moby Dick and his stress-free battle with the Divine Departure against awakened devil fruit user, Eustass Kid.

From Zoro to Franky, these are some One Piece characters who are inspired by real people.
Shanks can also use all three haki, and his power has impacted the world of One Piece. He has prevented an all-out war in Marineford and has control over the balance of power as the Marines always hesitate to fight him.
3The Five Elders
The Gods Of Mariejois
The five elders are bureaucrats running the world from the shadow. They were forced out of their abode in Mariejois because the balance of power was at stake on Egghead.
Their haki on Egghead Island was like no other that evenLuffy’s Gear 5and the giants' haki could not penetrate their bodies. However, despite their immense haki, the haki of a mythical legend of the past, Joyboy, stored in a robot, was able to force them back to their dwelling in Mariejois.
While the elders stood at the peak of power in the series, they could not withstand Joyboy’s haki, and Roger also conquered the sea on their watch.
2Gol D. Roger
The Man Who Conquered The Sea
Gol D. Roger is second only because Joyboy’s haki still influences the world 800 years later. During Roger’s time, his haki was so powerful that he could rival Whitebeard’s Gura Gura no mi, a fruit capable of destroying the world.
Also, he repeatedly clashed against Garp, conquered the seas, and created a legacy that even the World Government feared that someone would inherit his will. Roger performed all these great feats without a devil fruit.
Roger had all three haki: armament, conqueror, observation, and extraordinary mastery of this power system without any devil fruit, which showed why he was called the king of all pirates.
A Haki That Transcends Time
The number one spot belongs to a figure that is so powerful that his haki still echoes across time. Haki is not just about willpower alone, but a manifestation of someone’s will, and for Joyboy, his will was strong enough to survive the void century.
Joyboy stored his hakiin a knot for Emet to use when it was most important. On Egghead, the five elders proved to be formidable enemies even for Luffy’s Gear 5, but it was Joyboy haki that subdued them.
In the story, even though the likes of Roger, Shanks, and Garp are feared across the world, they haven’t shown a haki that can last for a long time and still influence the battlefield. This feat is enough to question what kind of haki he wielded during his time.
