#10 – MONKEY D. LUFFY
Luffy has gained an extremely high mastery of Busoshoku Haki. In Wano, he has advanced his Busoshoku Haki, allowing him to project it from his palm as well as progress even further by destroying objects he touches from the inside.
Luffy possesses Haoshoku Haki, a very rare type of Haki whose users are said to have the qualities of a king. This power was latent within him. Luffy initially tended to use Haoshoku Haki unintentionally.
Silvers Rayleigh then taught him about this power on Rusukaina, and Luffy trained to use it at will. After the timeskip, at Fish-Man Island Luffy was able to knock out 50,000 members of the New Fish-Man Pirates in an instant. When he fought against fellow Haoshoku Haki users Chinjao, Donquixote Doflamingo, and Charlotte Katakuri, their clashes created a notable effect similar to lightning. Even when unconscious, Luffy could still use Haoshoku Haki.
While fighting Kaido on Onigashima, Luffy came to understand that he could use his Haoshoku Haki to imbue his arms and legs and exponentially increase his attack power, becoming one of only a handful of Haoshoku users known to achieve this advanced technique. With this new skill, Luffy dramatically enhanced the destructive capabilities of the advanced Busoshoku Haki attacks becoming capable of striking Kaido with immensely powerful blows without even making direct contact with the Emperor’s body. When Luffy and Kaidou clashed again, the two of them split the clouds in the sky with their conflicting Haoshoku, a feat previously only seen achieved when two of the Four Emperors fought each other. This may indicate that Luffy’s Haki has ascended to the same level as that of the strongest pirates in the world.
Luffy first instinctively used Kenbunshoku Haki during the war at Marineford. After pushing his Kenbunshoku Haki to its peak during his fight against Katakuri, Luffy gained the ability to see into the future to a limited extent. He can now see the future as fluidly as Katakuri, as shown when he helped Hyogoro dodge multiple attacks from Alpacaman and Madilloman before they happened.
#9 – KOZUKI ODEN
Oden was an extremely powerful master of Busoshoku Haki, which is known as “Ryuo” in Wano. It is most noted as he was the only samurai who tamed the Meito, Enma despite its dangerous Haki-draining properties, which even Kin’emon, the Nine Red Scabbards’ Leader feared, displaying his supreme mastery compared to Zoro whose entire arm was emaciated after a single slash wielding Enma.
Even at age 18, Oden was masterful in using Ryuo, as he imbued both his swords (Ame no Habakiri and Enma) hardening them, letting him cleanly bisect the enormous Mountain God in a single slash. A true testament to his prowess, at age 39, Oden was able to wound the nigh-indestructible Kaidou while in his dragon form, giving him a permanent scar.
Oden also possessed the ability to use Haoshoku Haki and Kenbunshoku Haki.
#8 – YAMATO
Yamato possesses Haoshoku Haki, a very rare form of Haki whose users are stated to have the qualities of a king. Yamato was shown to have unleashed this Haki while running wild through Onigashima as a child, knocking out many of her father’s subordinates. As an adult, Yamato has demonstrated the advanced technique of imbuing Haoshoku, with her kanabo emitting streams of a dark lightning-like substance when performing the Raimei Hakke technique.
Yamato is a highly skilled user of Busoshoku Haki, having imbued her hand and kanabo with it while preparing to attack Hatcha, resulting in a lightning-like effect. She can use Busoshoku Haki to an advanced degree, being capable of projecting it a great distance forward and hitting faraway opponents with tremendous force with a simple kanabo swing.
Yamato also possesses Kenbunshoku Haki.
#7 – 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.
#6 – 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.
