Shanks is recognized as the master of conqueror's haki and the killer of observation haki too. He is also one of the few pirates who can use all three types of haki. Shanks has mastered conqueror's haki and made several members of the Whitebeard pirate crew faint during his visit.
Kenbunshoku Haki, one of the three Haki types in One Piece, grants the most powerful pirates unfathomable abilities. From sensing people's morality and emotions to being able to predict movements in battle, this form of Haki allows users to tap into a sixth sense that provides impressive precognitive abilities.
He is a specialist of Observation Haki, Ryuo, and also Conqueror's Haki. Among all the Haki types, however, Luffy is especially skilled at using Conqueror's Haki, which is his best Haki type.
Conqueror's Haki, also known as the Haki of the Supreme King, is the rarest form of Haki that only a few people in the world of One Piece are born with. Unlike the other two Haki types, Conqueror's Haki can't be learned through training and is only possessed by those who are born with the spirit of a king.
Monkey D. 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.
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.
Zoro was the first person who accepted Luffy's invitation and joined the latter on his journey to become the Pirate King. 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.
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.
As fans know, Nami doesn't wield any form of Haki in the story so far. Haki is a power that Rayleigh described to be the manifestation of the user's spirit. Every person in the One Piece world possesses Haki, however, not everyone is able to bring this latent skill out.
Luffy can use all the forms of basic Conqueror's Haki with great control and although his advanced Conqueror's Haki usage is a bit crude right now, he's sure to improve it in the future. During his fight against Kaido, he was able to hurt the Yonko and drop him to his knees with just a few punches.
What episode is Luffy Gear 5? Luffy's Gear 5 first made its appearance in the manga chapter 1044. So based on the current anime's progression, we will get to see Luffy Gear 5 in any one of the episodes between 1065-1070.
Gear 10th Luffy is Luffy's ultimate form from the upcoming speculative fan-made sequel to One Piece, Son of the Pirate King. Luffy has continuously trained his haki and Devil Fruit powers during his time as Pirate King until he achieved this gear.
Roger was the epitome of the greatest Haki user as he possessed all three major Hakis known in the world of One Piece. He was the captain of the famous Roger pirates, which consisted of powerful people like Rayleigh, Shanks, Buggy, and many others.
Throughout One Piece's two-year timeskip, Roronoa Zoro was trained by Dracule Mihawk on Kurainaga Island. The legendary swordsman's instruction primarily focused on Armament Haki, but by the end of their time together, Zoro was consciously able to use both Observation and Armament Haki.
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.
Those who have mastered the fourth form of Haki will be able to manipulate nature as they see fit. They can cause living organisms to grow rapidly or die rapidly (though not resurrect them), and make objects move with the force of their minds, akin to telekinesis.
While this is shown to be a very rare gift among the world as a whole, it is noted by Don Chinjao that the New World is filled with numerous others who possess the ability to use this Haki. He explains that Luffy will most certainly encounter them and fight them for the title of Pirate King.
These effects are a red aura (in Luffy's case) a green flame-like aura (in Sai's case), and a steam-like aura (black and purple for Zoro, Fujitora, Sanji, The Marines, purple for Kin'emon; and pink for Kanjuro). Also, when used to cover the whole body, users' Haki gets a purple luster instead of regular gray.
In the anime, the user of Haoshoku Haki has a dark purple aura around him.
So this purple tint to his haki could've been his spirit's nature, the same to Luffy where he got his own shade. This concept may rely on the anime but just remember that the anime does have connection with Oda. So it is very likely he told them to make it in that way.
The circumstances surrounding Zoro's left eye aren't a complete mystery; at the very least fans know that it happened sometime during the two-year time skip. During this time, each member of the Straw Hat crew committed to training and growing stronger.
Zoro wanted to see if he was worthy of Mihawks little knife necklace thing so he threw it it the air (like his cursed sword) and it slashed his eye which meant he still wasn't worthy to wield that knife.
In the two-year time skip, Zoro trained under Dracule Mihawk, popularly known as Hawk Eyes Mihawk. One of the popular theories is that the scar on Zoro's left eye is a training mishap. Many believe that Zoro lost his left eye during his training in some sort of accident or battle.
