#5 – SENGOKU
Sengoku was the Fleet Admiral of the Marines before the timeskip, succeeding Kong and preceding Akainu.
He was also one of the major figures along with Whitebeard, Shiki, and Monkey D. Garp during the times when Gol D. Roger was still alive, and still continues to be in the present, even after his retirement from the Marines.
Sengoku is one of a very small number of people who can use all three types of Haki: Kenbunshoku Haki, Busoshoku Haki, and Haoshoku Haki.
#4 – BIG MOM
Big Mom was first seen using Haoshoku Haki at Sanji and Pudding’s wedding to knock a man out for questioning her relationship with Mother Carmel. When her portrait of Carmel was destroyed, a distraught Big Mom unleashed her Haki, which, along with her loud screams, incapacitated most of the party guests.
Big Mom has vast mastery of Busoshoku Haki. By hardening her arm, she easily blocked Luffy’s Gear Fourth Kong Gun with just one arm, a tremendous feat as Luffy’s Kong Gun is powerful enough to break through powerful Haki based defenses of highly skilled Busoshoku Haki users such as Doflamingo, Cracker, and Katakuri. Like Luffy’s Gear Fourth, her Busoshoku sports flame marks at its ending.
She also possesses the ability to use Kenbunshoku Haki.
#3 – SILVERS RAYLEIGH
Rayleigh is shown to possess great mastery of Haki, and made use of all three types while teaching Luffy about them, and training him in the basics.
Rayleigh has mastered Haoshoku Haki to the extent that he can render a specific target completely unconscious. He is able to do this without adversely affecting anybody else near the initial target. He disabled an entire hall room of hostiles with this power, save for the Kid Pirates and Heart Pirates.
Rayleigh has an extremely high level of skill in Busoshoku Haki, allowing him to effectively bypass the powers of a Devil Fruit user and touching the “substantial body” beneath whatever protection the fruit provides as seen when he used Busoshoku Haki to kick and redirect an attack from Admiral Kizaru. Rayleigh can utilize an advanced application of Busoshoku which enables him to emit his Haki a short distance without a medium. He is also able to use a high-grade version of this technique, where Rayleigh can channel his Haki into his opponent, letting him destroy them from the inside out, which he first used to destroy Camie’s collar.
Rayleigh is highly proficient in Kenbunshoku Haki, able to sense the emotions and nature of others. He could also use it to sense the strength of others on a wide scale. The incredible mastery Rayleigh has over this kind of Haki is also shown by the fact that he can sense people all over the island he is currently on while most people can sense only in their immediate vicinity.
#2 – SHANKS
Shanks has mastered to full extent all three types of Haki. Even Whitebeard complimented Shanks for his Haki when he used it on his visit.
Shanks showed great mastery over Haoshoku Haki on board the Whitebeard’s ship. A large number of Whitebeard’s crew (experienced men who have survived in the New World) lapsed into unconsciousness and the ship itself began to take physical damage from Shanks’ mere presence. Whitebeard’s men attributed this to his superior Haki.
Shanks has great mastery over Busoshoku Haki, as shown during the Battle of Marineford, with his Haki infused sword he easily block Akainu’s magma enhanced punch that is powerful enough to burn the strongest enemies such as Ace, Jinbe, and even the Yonko Whitebeard.
Shanks also has full mastery over Kenbunshoku Haki, though he was never seen using it.
#1 – WHITEBEARD
Whitebeard was known as “The Strongest Man in the World” and “The Man closest to One Piece” after Gol D. Roger’s death.
His Haoshoku Haki was displayed against his longtime rival, Gol D. Roger. Their joined Haoshoku Haki clash cracked the air, creating an effect akin to lightning and generating a shock wave larger than the island; repelling the giant trees around them alongside the crewmates of the Roger and Whitebeard Pirates and nearly capsizing the Moby Dick.
Whitebeard possessed an immense mastery of Busoshoku Haki. 30 years prior in his prime, his Busoshoku Haki coated Murakumogiri, was powerful enough to defend against both Enma and Ame no Habakiri, 21 O Wazamono Meitos, another superior Busoshoku Haki master who had hardened them using Hak. He also used Advanced Busoshoku, proving his mastery by hardening Murakumogiri to the point where a black flame-like aura as large as himself formed around its blade and emitted Haki from a short distance, causing a gigantic shock wave that spread across the island after clashing against Gol D. Roger despite their weapons not connecting.
Whitebeard was also masterful in using Kenbunshoku Haki. It was first shown 30 years prior after both he and the Whitebeard Pirates, as he could sense “something incredible” coming from a vast distance towards them. In the bay of Marineford, he predicted Crocodile’s sudden attack but did not move, knowing that Luffy would block it. However, due to both his age and worsening health, he failed to predict Squard’s betrayal and thus got injured, something which, according to Marco, was totally unexpected from the Yonko.
