Haki Manga Infobox


Haki (覇気, Haki) is a mysterious power that is found in every living being in the world. It is not that different from the normal senses. However, most people do not notice it or fail to awaken it. Broadly, there are two types of Haki common to everyone, given the proper training; however, there is a third type that only a certain group of "chosen ones" are said to possess. In simple terms, Haki is an ability to sense spiritual energy and overpower enemies.


Haki, unnamed at the time, was first seen when Tiger used it against the Lord of the Coast to save Luffy when he was a child from the wrath of the Sea King. The term "Haki" was first coined and used much later when Blackbeard was commenting on Luffy's bounty in Jaya, and was hinted at during Tiger and Shanks' visit with Whitebeard.

The underlying concepts of Haki were introduced during the Sabaody Archipelago and Amazon Lily Arcs. The concept was clearly explained by Rayleigh to Luffy at the start of the latter's training on Rusukaina Island.

Haki is dormant in every living person, but it's rare for most people to ever awaken that ability. Intense training can awaken it, as can extreme shock, such as with Coby during the battle of Navyford. Two known people (Aisa and Otohime) were born with the ability.

Due to the fact that Haki originates from an individual's spirit and not their body, even if the user's spirit is transferred into another body, they are still capable of using Haki as if they were in their original body.

Known UsersEdit

So far the characters who have clearly shown the use of Haki or have been stated to be able to use it are:

Types of HakiEdit

Haki is separated into three categories, or "colors": Observation Haki, which grants users a sixth sense of the world around them and limited precognitive abilities.; Armament Haki, which allows the user to use their spirit as armor to defend against attacks or to make their own attacks more potent; and King Conqueror's Haki, a rare type of Haki only one in a million can use which grants the user the ability to overpower the will of others. Most people who can use Haki tend to have a type they are better at and as a result focus on that type. However, a person can improve their abilities with all the types of Haki, it just requires more work.

Observation Haki

Observation Haki (見聞色の覇気, Kenbun-shoku no Haki), also known as Mantora (マントラ, Mantora) on Skypiea, is a form of Haki that allows the user to sense the presence of others, even if they are concealed from view or too far to see naturally. With enough skill, one can use this Haki to predict an opponent's moves shortly before they make them, thereby making the attack that much easier to evade. This prediction appears to the user as an image or brief "premonition" of what the opponent will do in the user's mind's eye, and the damage the user will take if the attack actually "hits". It appears that the more killing intent the enemy has, the easier they are to predict. Although, more skilled users can predict future moves whether there are ambient murderous intents or not.

It was first introduced under the name Mantra when Satori used it to fight Sanji, Luffy, and Usopp as they went through the I.Q. Orb Test. Aisa is the only known Shandian who has this ability. It served as a plot point when she helped Luffy locate Eneru. It varied in strength between users, with Eneru's seemingly being the strongest. With his Cursed Fruit, the Rumble-Rumble Fruit, Eneru could pick up electromagnetic waves, allowing him to overhear conversations and everything around him; this extended the range of his Mantora to cover roughly all of Skypiea. By comparison, most of the other priests could only keep track of people nearby.

The first time it was seen being used and referred to as Haki was during Luffy's battle on Amazon Lily with the Boa Sisters. Later, Rayleigh explained Haki to Luffy and confirmed that "Mantora" is the Skypiean name for the ability.

Though the power allows the user to predict most attacks, it can be circumvented by various means. It cannot predict inherently random attacks; for example, Luffy managed to bypass Eneru's Mantora by bouncing his fists off a nearby wall, to prevent himself and thus Eneru from knowing where they would land. Tying in with the inability to detect random attacks, Observation Haki seems to be linked to the target's own awareness of themselves and their surroundings. Eneru failed to discern the presence of Luffy inside the giant snake Nola, only detecting him after he escaped. Similarly, Aisa could not detect how the battle was progressing with her Mantora while inside Nola and only found out what happened after she and Luffy escaped. It also does not make the user any faster than normal, so the user's ability to dodge is dependent on their speed; Eneru was unable to avoid Luffy's finishing move because it was moving too fast, even though he was able to predict it. Likewise, Luffy's Gear Second was able to outpace Sandersonia Boa, despite her ability to read his moves. It also seems to falter if the user loses their concentration. Satori lost the control of his Mantora when Luffy unexpectedly brought the string of exploding balls right to him, enabling Luffy to grab him from behind when the smoke cleared, and Gedatz lost to Chopper because he lost his concentration and his Mantora faltered.

This type of Haki can also allow the user to sense the emotions and nature of others. For example, Otohime used this Haki to sense the sufferings and emotions in the heart of a Mermen thief as well as hear the screams coming from Tiger Fisher's heart. Another example is that Aisa was able to sense Wyler's aggressive nature with this Haki.

It appears it's also possible for the user of this Haki to sense the strength of others as well. This was shown when Rayleigh used this Haki to sense that there were 500 creatures on Rusukaina who were stronger than Luffy at that time.

Armament HakiEdit

Armament Haki Anime Infobox

Armament Haki

Armament Haki (武装色の覇気, Busō-shoku no Haki) allows the user to create a force similar to an invisible armor around themselves. Similar to Iron Body, this allows the user to defend against attacks that would otherwise cause them harm. Only significant physical force can overcome this defense; for example, Luffy striking Marigold Boa hard enough with Gear Second techniques to send her reeling.

Naturally this "invisible armor" can be used as a weapon to strike others with. It can be used to augment the user's own attacks, projected ahead of the user as pure brute force, or imbued in weapons to increase their effectiveness. Any attack enhanced by Armament Haki hits immensely harder than it would normally be without it. The Kuja's Haki-imbued arrows, for example, are capable of penetrating solid stone.

This type of Haki also has the ability to bypass the powers of a Cursed Fruit user, touching the "substantial body" beneath whatever protection the fruit provides, such as the case of body-altering Cursed Fruits such as Logia users. However, unlike Sea-Prism Stone, it does not negate a user's Cursed Fruit powers, allowing them to defend themselves, and continue fighting normally. By the same effect, this Haki can also be used as a higher level of offensive, more so than just bypassing a foe's Cursed Fruit powers. It can be used to harden parts of one's body, turning the area black, making the user denser and more formidable, and giving their attacks greater power. This was first used by Luffy to harden his arm and later his forehead, a technique he called Armament Koka. This technique wasn't seen again until Vergo used it on Punk Hazard, followed shortly thereafter by Chaser Smoker.

Armament Haki works independently of the user's Cursed Fruit, as shown when Luffy uses it to enhance his Gear Third attack underwater. This type of Haki may not be equipped to attacks that are not from one's body except for weapons, or anything generated from one's own body (like Kizaru's laser beams, Marco's flames or any other energy/non-solid attacks based on Cursed Friuts). So, those who attack with parts of their body can combine their Haki and Cursed Fruit powers.


  • Armament: Hardening (武装色 硬化, Busō-shoku: Kōka): This technique somehow uses Armament Haki to harden the body (or parts of it) and weapon which the user is holding. It was first seen used by Luffy D. Monkey, in combination with Gear Third, in order to use his Gum-Gum Iron Elephant against the Kraken. The arm became black and shiny and notably did not cause the usual side effect for Gear Third on release. Vergo, Chaser Smoker and Zephyr are able to either use this technique or do something similar to it as they have demonstrated an exact likeness of this Haki technique; Zephyr had earned the nickname "Black Arm" because of his mastery of it. It can also be imbued into weapons, as Vergo utilized it on a bamboo stick, and Chaser on his Nanashaku Jitte, the latter indicating Armament Haki can be used in conjuncture with Sea-Prism Stone.
    • Head: Hardening (頭武装, Atama Busō): Used by Luffy, he imbues his forehead with Armament: Hardening to harden it.
    • Gear 2nd: Armament (ギアセカンド 武装, Gia Sekando Busō): Used by Luffy, he imbues his fist with Armament: Hardening while under the effect of Gear Second to harden it, which also seems to have the added effect of igniting it. It was first used in preparation for Gum-gum Red Hawk against Hordy Jones.

King Conqueror's HakiEdit

King Conqueror's Haki Anime Infobox

King Conqueror's Haki

King Conqueror's Haki (覇王色の覇気, Haō-shoku no Haki) is a rare form of Haki that cannot be attained through training and only one in a million people carry it. It was first demonstrated by Tiger, when he used it to scare off a Neptunian. Later on, during a meeting with Whitebeard with Shanks, he used it to knock out most of the crew, which the few still standing attributed to his superior Haki. Luffy first displayed the effects of this type of Haki against Duval's bull, Motobaro, much to everyone's confusion. He displayed it again on Amazon Lily while battling the Boa sisters, knocking out a large portion of the audience observing the match. This is also the first time it is referred to by name. Luffy's exhibition of it during the Navyford War was enough for the Marine admirals to become wary enough of him that they prioritized his elimination afterwards.

After the timeskip, Luffy is proficient enough to tame monsters, as well as knock out a selected group of individuals without affecting any of the bystanders using King Conqueror's Haki, displaying his new-found proficiency in the skill.

This type of Haki grants the user the ability to dominate the wills of others. The most common usage in the series so far is knocking those with weak wills unconscious. Whilst inexperienced users are restricted to merely overpowering the will of one individual or blindly knocking out weak-willed people around them, those with more expertise can pick out weak-willed individuals in a large group and knock them out without affecting those around them. However, those with stronger wills can resist or even ignore the effects of King Conqueror's Haki. The ability to knock someone out depends on the difference in strength between the person using Haki and the person or persons the user is trying to knock out. The greater the power gap, the easier it is to knock the victim out. According to Rayleigh, while this type of Haki cannot be attained through training, it can be improved through training, as it grows as the user's spirit grows. It seems that upon recovery, victims of King Conqueror's Haki experience the sensation of chills running through their body. However, it presumably wears off after a short period.
