Luffy has mastered all three types of haki, including Kenbunshoku Haki (Observation Haki), Busoshoku Haki (Armament Haki), and Haoshoku Haki (Conqueror's Haki). He can even use several subforms of the hakis, which makes him one of the most powerful haki users in the One Piece world.
Luffy has mastered all three types of Haki, including Observation Haki, Armament Haki, and Conqueror's Haki, and many of its sub-types.
5 Armament Haki Subtype 4: Internal Destruction
The rarest subtype of Armament Haki, known as Internal Destruction, has only been demonstrated by two characters — Monkey D. Luffy and his mentor, Silvers Rayleigh.
7 Roronoa Zoro
Zoro is a very powerful fighter and he possesses all three types of Haki. Zoro was able to use Conqueror's Haki unknowingly against Kaido.
Ace might not have the strongest of Haki, but he was one of the few characters who were able to use all three kinds of Haki. Ace has been confirmed to be a user of both Armament and Observation Haki in his novel.
Akainu has two Haki (Busoshoku and Kenbunshoku). Akainu use Busoshoku Haki to imbued himself and defend himself such as blocking Whitebeard's attack (along with Kizaru and Aokiji).
Conqueror's Haki is one of the rarest powers to exist in the One Piece world. Unlike the other two Haki forms, this power isn't accessible by everyone but exists within only a chosen few. Its basic level allows the user to intimidate and overwhelm those who have weaker wills.
Nami is also a competent fighter, although among the weakest in the crew. She mainly makes use of her wits in combat to get the better of her enemies. Surprisingly, One Piece 1058 showcased her using Conqueror's Haki in what appeared to be a gag scene.
Sanji is also a skilled user of Armament Haki and he has displayed the skill on several occasions, especially in the Wano Country arc. To defeat Queen the Plague, Sanji used his Haki to coat his body and improve its durability against the high-temperature flames of Ifrit Jambe.
Three overarching forms of Haki (Armament, Observation, and Conqueror's) exist in One Piece, each of which is divided into further subclasses.
Roger used advanced forms of conqueror's haki as he imbued his sword with conqueror's haki and clashed with Whitebeard. He also used advanced armament haki for more powerful sword attacks. Additionally, Roger possessed the observation haki, thus, making him the strongest haki user of all time in One Piece.
Dragon is almost certainly going to be a user of Conqueror's Haki as well just like his son. In Marineford, Luffy's Conqueror's Haki was attributed to Monkey D. Dragon, meaning he is already implied to be its user despite not having used it so far. In the future, fans will certainly see him make use of this ability.
In the anime, some Haki users are shown surrounded by different color auras (such as red for Luffy, purple for Doflamingo or pink for Big Mom) even if they are not using Haki at that moment.
Nico Robin is the archaeologist of the Straw Hat Pirates and one of the crew's strongest fighters. While Robin should've been an Observation or Armament Haki user, given that she spent quite a lot of time around those who wield it during the timeskip, she doesn't equip this skill.
Appearance. Zoro is a tall, muscular young man with lightly tanned skin and black eyes. He always carries his three swords along with him, bundled up with a green haramaki over his right hip, allowing him to easily draw them with his left hand.
4 Hana Hana no Mi
The Hana Hana no Mi is a powerful Paramecia-type of Devil Fruit eaten by Zoro's crewmate, Nico Robin. This Devil Fruit allows the user to sprout any part of their body from anywhere. With advanced control, the user can even create an entire clone of themselves.
The real form of Luffy's devil fruit
Luffy awakened his powers during his fight with Kaido and transformed into a mythical being called Nika, the Sun God. This form is also called Gear 5. Once transformed, Luffy undergoes a drastic change where his hair and clothing turn white and his eyebrows resemble spirals.
Luffy has mastered all three types of haki, including Kenbunshoku Haki (Observation Haki), Busoshoku Haki (Armament Haki), and Haoshoku Haki (Conqueror's Haki). He can even use several subforms of the hakis, which makes him one of the most powerful haki users in the One Piece world.
The Nami Nami no Mi is a Paramecia-type Devil Fruit that allows its user to become a "Tearful Woman" (涙の女, Namida no On'na) as it enables them to change the the properties of their tears. "Nami" comes from the word "Namida" (なみだ), the Japanese word for "tears".
White Haki spirit color is the rarest color and cannot be obtained with robux.
