Haki is a mysterious power that is found in every living being in the world. However, most people do not notice it or fail to awaken it.
In simple terms, Haki is an ability to sense spiritual energy (Kenbunshoku Haki/Observation Haki), use life force (Busoshoku Haki/Armament Haki) and overpower enemies (Haoshoku/Conqueror’s Haki).
There are very few people who can use all 3 types of Haki. Let’s have a look at them:
#10 – CHINJAO
Chinjao is one of the very small number of people who can use all three types of Haki.
He is highly proficient in Busoshoku Haki, which he uses to harden his fist to augment the force of his punch and clash evenly with Luffy. The clash of their Haki enhanced strikes resulted in the air itself crackling. He prominently uses it to harden his head in order to split open the Jewel Ice Sheet.
Chinjao has also shown the ability to use Haoshoku Haki when he knocked out many of the competitors in Block C without laying a finger on them, an impressive feat considering that most of the participants in the Corrida Colosseum are strong fighters.
Chinjao also possesses the ability to use Kenbunshoku Haki.
#9 – DONQUIXOTE DOFLAMINGO
Doflamingo used Haoshoku Haki to knock out the majority of G-5 soldiers at Punk Hazard. His Haoshoku Haki first awakened when he was around ten years old, when being pursued again by North Blue citizens who tried to continuously torture his family in revenge, knocking them all out, thus saving him.
Doflamingo has significantly high skill in Busoshoku Haki. His Busoshoku Haki is strong enough to counter Law’s spatial slicing powers, though it still not strong enough to defend against the sharpness of Law’s sword as he cut his hand slightly after grasping the blade.
Doflamingo also possesses the ability to use Kenbunshoku Haki.
#8 – BOA HANCOCK
Boa Hancock possesses Haoshoku Haki, which she can use to knock out a weak-willed people with a massive burst. Her exact level of mastery has yet to be demonstrated.
She is highly skilled in Busoshoku Haki which she can combined with her kicks to bypass a Logia’s intangible defenses as she kicked away Smoker, a physically powerful Marine with sufficient force to release his stranglehold on Luffy, whom Smoker pinned to the ground.
Hancock possesses also the ability to use Kenbunshoku Haki.
#7 – CHARLOTTE KATAKURI
Katakuri has extraordinary mastery of Kenbunshoku Haki, having trained to such a degree that he can see slightly ahead into the future.
He is also an extremely powerful Busoshoku Haki user, as shown when he imbued his mochi leg with it in order to bludgeon and injure Luffy. When his Haki is compressed and focused when performing his Zan Giri Mochi attack, Katakuri’s Haki becomes flame-shaped like Big Mom’s Haki and Luffy’s Haki when he uses Gear Fourth and the luster of it is light blue.
Katakuri is also able to use Haoshoku Haki, as shown when he released a large burst along with Luffy’s own Haoshoku Haki in order to knock out Charlotte Flampe and her subordinates as punishment for their interruption.
#6 – MONKEY D. LUFFY
Luffy is able to use Haoshoku Haki, a type of Haki possessed only by one in a million people. Luffy used this ability several times in the series, as it was the type of Haki that manifested the earliest. Before training under Rayleigh, Luffy displayed limited to no control over this ability, and did not seem to realize he had it, but used it on instinct whenever it seemed to be most needed, and could still use it even when extremely injured. This Haki has become Luffy’s specialty.
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.
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.
