Conqueror’s Haki is a rare form of Haki that allows the user to exert their own willpower over others. Unlike the other types of Haki, Conqueror’s Haki cannot be attained through training, instead its users must be born with the ability and can only learn to control it after discovering that they have it.
Basic Tecniques of Conqueror’s Haki are:
Conqueror’s Haki can be used to temporarily dominate the psyche of others, intimidating them to point where they are frozen with fear and/or forcing them into submission, causing the victim to retreat, or obey the users commands for a short time.
By simply staring intently into an victims eyes, a Conqueror’s user can immediately inflict tremendous fear into the creature’s psyche, causing it to either run away or immediately become docile; the animal may also pass out shortly afterwards.
By overpowering the will of those around them to an even greater degree, a Conqueror’s Haki user is capable of knocking people and animals in their vicinity unconscious. Whether or not a person is rendered unconscious depends on the degree of their strength in comparison to the user’s.
Sufficiently powerful Conqueror’s users are frequently capable of going up against large hordes of enemies and incapacitating most, if not all of them in an instant.
If used with a sufficient degree of power, Conqueror’s Haki is capable of damaging inanimate objects and structures in the user’s vicinity. This was first shown when Shanks used Haoshoku on the Moby Dick to such a degree that it not only knocked out many of the Whitebeard Pirates around him, but also slightly cracked some of the wood composing the ship, which had withstood the incredibly harsh sailing conditions of the New World since the era of Gol D. Roger, more than two decades ago.
When two Conqueror’s users clash, they will generate thin lightning-like streams of colored energy that crackle.
Additionally, the force of a Conqueror’s Haki clash will create shockwaves that will shake the surrounding area and can even blow away nearby people and objects. When Gol D. Roger and Whitebeard clashed, the resulting impact blew back all of the flora and fauna on the entire island and even exerted tremendous force on their ships on the coast. When Kaido fought Big Mom for half a day, Kaido’s subordinates were extremely concerned that they would destroy the fortress they were in and even the entire island of Onigashima in the course of a long battle.
Additionally, when Whitebeard and Shanks, and later Kaido and Big Mom, clashed with their Haoshoku, the resulting impact created a massive rift in the sky above them.
We recently discovered that there are also Advanced Techniques of Conqueror’s Haki. So far we only know one:
A very small number of particularly powerful Conqueror’s Haki users, stated to only be a “handful” by Kaido, are able to “infuse” their body and weapons with their conquering spirit in a way that is very similar to Armament Haki, greatly augmenting the power of their attacks. After infusing themselves with Conqueror’s, the Haki is emitted from the part it is focused at in the form of small dark lightning. This application provides such an immense boost in power, it allowed Luffy to clash evenly against Kaido, the man known as the strongest living creature in the world.
Luffy was able to strike Kaido without making physical contact with him and even deal him damage, whereas his earlier use of advanced Armament-enhanced attacks were “too shallow” and had no significant effect.
So far, only Roger, Whitebeard, Oden, Zoro, Kaido, Luffy and Big Mom have all been seen infusing Conqueror’s Haki.
