Kaido of the Beasts was feared as the “Strongest Creature in the World.” He was a master of all three types of haki — Conqueror’s Haki, Armament Haki, and Observation Haki. His most devastating ability was combining Advanced Conqueror’s Haki coating with his raw physical power, allowing him to split the skies with a single blow.
During the Wano arc, Kaido fought against the Nine Red Scabbards, the Worst Generation supernovas, Yamato, and finally Luffy — all in a single prolonged battle. His durability, stamina, and haki mastery were unmatched. Even in defeat, Kaido cemented his place among the greatest haki users in history.
⚡Haki Moments – Constantly used Conqueror’s Haki in battles, especially in his clash with Luffy. His Haki-coated Thunder Bagua could destroy entire mountains and overpower even Gear 4.

Whitebeard – Strongest Man in the World

Known as the “Strongest Man in the World,” Whitebeard’s haki was nothing short of legendary. His mastery over Busoshoku Haki (Armament) allowed him to clash evenly with Roger, while his Haoshoku Haki (Conqueror’s Haki) could knock out countless enemies with sheer presence.
Even in old age and hooked up to medical equipment, he went head-to-head with the Marines at Marineford, using haki to withstand attacks from admirals and shatter the battlefield itself. Whitebeard’s haki wasn’t just powerful—it carried the weight of a king, a father, and a warrior who could crush mountains and defend his crew till death. He’s not just a top-tier haki user—he’s a legend etched in One Piece history.
⚡Haki Moments – Clashed equally with Roger using Conqueror’s Haki. Even in his old age, he had enough Haki to overpower Vice Admirals and rival Yonko-level opponents.

Silvers Rayleigh – The Dark King

Silvers Rayleigh, the former first mate of the Roger Pirates, is a true master of all three haki forms. Even decades after Roger’s era, Rayleigh displayed immense skill by stopping Admiral Kizaru at Sabaody Archipelago and intimidating a Marine fleet.
He was also the mentor who trained Monkey D. Luffy during the two-year time skip, teaching him Advanced Observation, Armament, and Conqueror’s Haki. Rayleigh’s combat experience and mastery make him one of the most respected haki users in One Piece.
⚡Haki Moments – First shown using Conqueror’s Haki to save Camie the mermaid at the Human Auction House. Later, he stopped Admiral Kizaru on Sabaody and scared off a Sea King with just his presence.
7
Monkey D. Garp – The Hero of the Marines

Known as the “Hero of the Marines,” Garp is a living legend who rivaled the Pirate King without ever eating a devil fruit. His haki-infused punches, famously known as “Fist of Love,” could destroy mountains and battleships.
In his prime, Garp fought alongside Roger to take down Rocks D. Xebec, proving his strength and mastery over haki. Even in his old age, he showcased monstrous power during the Hachinosu rescue mission.
⚡Haki Moments – Never confirmed, but fought Roger and Rocks on equal terms. In the Egghead arc, his sheer presence and strength made many believe he has latent Conqueror’s Haki.

Monkey D. Luffy – Joy Boy Reincarnation

The current Joy Boy and future Pirate King, Luffy has unlocked the full potential of all three haki types. His Advanced Observation Haki allows him to see a few seconds into the future, his Advanced Armament Haki can destroy opponents from the inside, and his Advanced Conqueror’s Haki coating lets him fight without making physical contact.
In the Egghead arc, Luffy even repelled Saint Saturn and Gorosei manifestations, proving his haki is strong enough to challenge the highest powers in the world. With Gear 5 and his ever-growing abilities, Luffy’s haki mastery is still evolving.
⚡Haki Moments – Knocked out 50,000 Fish-Men on Fishman Island with a single burst of Conqueror’s Haki. Later, in Wano, he mastered advanced Conqueror’s Haki and used it to fight and defeat Kaido.

Shanks is feared across the seas despite having no devil fruit powers. His god-tier Conqueror’s Haki can knock out thousands of enemies instantly and even paralyze Admirals from a distance. He once stopped Kaido from reaching Marineford without a fight, purely through the pressure of his haki.
In the manga, Shanks’ haki clashes have split the skies, a feat only the strongest conquerors can achieve. His skill and aura make him one of the deadliest haki specialists in history.
⚡Haki Moments – He displayed overwhelming Conqueror’s Haki in Wano by knocking out Admiral Greenbull from miles away. His haki mastery is unmatched and feared by even top-tier characters.

Before Roger’s era, Rocks D. Xebec ruled the seas as the captain of the most dangerous pirate crew ever assembled. Legends like Whitebeard, Big Mom, and Kaido once served under him — a testament to his overwhelming power and charisma.
It’s believed Xebec mastered all three haki forms, especially Conqueror’s Haki, which he used to command and control some of the strongest individuals in history. His defeat required both Roger and Garp to fight together.
⚡Haki Moments – Led a crew of Kaido, Big Mom, and Whitebeard—only possible with immense Haki and dominance. Likely rivaled Roger and Garp in raw Conqueror’s Haki during the God Valley Incident.

Gol D. Roger – The Pirate King

Roger conquered the Grand Line without any devil fruit power, relying solely on his haki and swordsmanship. His Advanced Conqueror’s Haki allowed him to clash equally with Whitebeard, splitting the skies with each blow.
He was also one of the few who could read the Poneglyphs, guiding his crew to Laugh Tale and uncovering the True History. Roger’s haki mastery, combined with his leadership and will, secured his place as the Pirate King.
⚡Haki Moments – Fought evenly with Whitebeard using only Conqueror’s Haki clashes, without touching each other. His haki was powerful enough to shake the seas.

Imu-sama – The Eternal Ruler

The mysterious sovereign of the World Government for over 800 years, Imu’s existence is shrouded in secrecy. Surviving since the Void Century suggests an unnatural level of power, possibly including god-tier mastery of all three haki types.
Though their abilities remain unrevealed, Imu’s dominance over the Gorosei and the entire world hints at a power greater than any current character.
⚡Haki Moments -Though not shown yet, Imu commands the Five Elders and erased islands with god-like power. It’s highly likely Imu possesses Conqueror’s Haki at a divine or transcendent level.

Joy Boy (Void Century) – The Original Warrior of Freedom

Joy Boy was the legendary figure who stood against the 20 Kingdoms and fought Imu-sama during the Void Century. Known as the original warrior of liberation, he possessed haki on a scale that could shake the world.
It is said that even a small fraction of Joy Boy’s haki, locked in a single knot of will, was enough to send all Five Elders (Gorosei) flying back and force Imu-sama to kneel. This shows just how overwhelming his Conqueror’s Haki was — not just in strength, but in the sheer dominance of will.
With Advanced Conqueror’s Haki and the will to free the seas, Joy Boy’s legacy has been carried forward by Luffy. His feats remain in myths, but his name still inspires rebellion against tyranny even 800 years later.
⚡Haki Moments – When Luffy awakened his Devil Fruit in Gear 5, the Gorosei themselves withdrew, fearing what he had become. This transformation likely involved an ancient, supreme level of Conqueror’s Haki inherited from Joy Boy’s will.
🔥 Final Thoughts
From mythical figures like Joy Boy to modern legends like Shanks and Luffy, haki continues to shape the destiny of One Piece’s world. As the Final Saga unfolds, we may finally witness the full extent of Imu’s powers and the true history behind Joy Boy’s fight.
