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 take a look at them:
#16 – EUSTASS KID
Eustass Kid is one of the few people in the world who is capable of using all three forms of Haki.
According to Kaidou, Kid can use Haoshoku Haki. According to the new Vivre Card he can also use Busoshoku Haki and Kenbunshoku Haki.
#15 – CHINJAO
Chinjao 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.
#14 – 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.
#13 – 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.
#12 – 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.
#11 – RORONOA ZORO
Zoro can use Haoshoku Haki, a very rare form of Haki whose users are stated to have the qualities of a king. As of now, this power has laid dormant within Zoro and he is unaware he possesses it; he was first noted to have used it by Kaido after the Emperor was struck by Zoro’s Kyutoryu attack. During Zoro’s battle against King, he ended up using its advanced application, infusing it into his three swords, with all three emitted streams of black lightning signifying its infusion. As their battle continued on, Zoro managed to gain conscious control over the advance technique, infusing it into all three swords, or infusing it into Sandai Kitetsu to deal significant damage to King
Among the Monster Trio, Busoshoku Haki is Zoro’s area of expertise, having mastered imbuement under Mihawk over the two-year timeskip, and almost always uses it in serious battles.
Zoro’s proficiency in Busoshoku Haki was shown once again in Wano, when he imbued three individual weapons with Haki. It was further shown, as after receiving the Meito, Enma, a sword renown for rapidly draining the wielder’s Haki, despite having his Haki drained from his arm after using it once, he was able to retake his Haki in seconds, then within a couple days, he learned how to wield the sword comfortably.
Realizing he was at his limits, having taking too much damage, Zoro strengthened his Kyutoryu: Asura using Busoshoku and Haoshoku Haki, which has allowed him to leave a permanent scar on Kaido in his hybrid state.
Zoro can also use Kenbunshoku Haki, as shown when he was asked by Luffy if he could sense a “wild animal” in the Ryugu Palace, which he stated he could. Zoro also detected Batman attempting to kill Tsuru with an arrow fired from a far distance in the air.
