Three overarching forms of Haki — Armament, Observation, and Conqueror’s — exist in One Piece, each of which is divided into further subclasses. Unsurprisingly, there are five Haki users in the Straw Hat Pirates, most of whom are skilled in the application of this power. Their combined abilities have already played a major role in their rise to prominence post-timeskip. Moving forward, the crew will almost certainly continue to develop their Haki-related abilities as they employ its various forms.

Updated on December 27, 2023, by Ajay Aravind: With the conclusion of the Raid on Onigashima, One Piece prepares to move into uncharted waters, ushering in what has been confirmed to be its final saga. As such, we’ve updated this list with more information about which Straw Hats can use Haki.

5Usopp Can Now Perceive The Aura Of His Target With Haki

Traditionally, Usopp has proven himself to be the weakest member of the Straw Hat Pirates, generally being matched against the weakest members of enemy forces. Further, he’s arguably the most cowardly character in the story, even if he occasionally rises to the occasion. This is why fans have wondered if Usopp has Haki in the first place. However, as One Piece‘s narrative has progressed, so have the mischievous sniper’s abilities as a sharpshooter. Alongside Jinbe, Sanji, Zoro, and Luffy, Usopp is one of only five Straw Hat Pirates who has unlocked the ability to use Observation Haki.

Armed with Observation Haki, Usopp is able to hit targets far more effectively than before. During the Straw Hat Pirates’ battle against the Donquixote Pirates, Usopp was forced into a situation where he needed to snipe Sugar, one of the crew’s executives. Unfortunately, he was extremely far away from his target, and a variety of buildings, objects, and people were in his path. By awakening his Observation Haki, Usopp succeeded in perceiving the aura of his target, allowing him to hit his target and assist in the takedown of the dastardly Doflamingo. All things considered, however, Usopp still doesn’t have access to the other two forms of Haki.

4Sanji Is Bound To Learn Conqueror’s Haki At Some Point

The Straw Hat Pirates are all powerful fighters, but when it comes to combat, Luffy, Zoro, Jinbe, and Sanji stand head and shoulders above their companions. Accordingly, it only makes sense that the latter of this quartet would possess an impressive level of Armament and Observation Haki. Although his genetic modifications as a member of the Vinsmoke Family are dangerous on their own, they are made significantly stronger thanks to Sanji’s Haki skills. Ultimately, these abilities are what enable the world-class chef to defeat a monstrous threat like Queen of the Beast Pirates without any assistance.

One Piece‘s two-year timeskip was not kind to Sanji, as he spent almost 24 consecutive months avoiding the inhabitants of Kamabakka Kingdom while away from the Straw Hat Pirates. However, in the course of doing so, he unlocked the ability to consciously use Observation Haki, allowing him to remain on high alert at all times. Presumably, Sanji also unlocked the ability to use Armament Haki while in the Kamabakka Kingdom, as he almost immediately used it to defeat a Pacifista upon his return to Sabaody Archipelago. It’s only a matter of time before Sanji figures out how to use Conqueror’s Haki.

3Jinbe Knew Two Forms Of Haki Before Joining The Straw Hats

As the latest addition to the Straw Hat Pirates, Jinbe is one of the most experienced fighters aboard the Thousand Sunny. The helmsman joins Monkey D. Luffy’s crew during the Wano Country arc. However, prior to this arc, he served as the captain of the Sun Pirates. Jinbe’s time as a captain eventually led him to become one of the Warlords of the Sea — a position that allowed him to practice his use of both Armament and Observation Haki on a regular basis. During his fight with Who’s Who of the Beast Pirates, Jinbe’s skill as a Haki user became apparent, as he was ultimately able to defeat the Ancient Zoan-type Devil Fruit user by infusing his Fish-Man Karate skills with his Armament Haki.

Unlike the other Haki users in the Straw Hat Pirates, fans don’t know when or how Jinbe learned Haki. Two years before the events of One Piece, the talented fish-man used Armament Haki to fight against Portgas D. Ace, allowing him to bypass the Logia-type Devil Fruit user’s natural defenses. While it seems unlikely that Jinbe would have learned how to use Haki during the life of Fisher Tiger, he almost certainly awakened these abilities before his appointment as a Warlord of the Sea. This also raises an important question: Does Jinbe already know Conqueror’s Haki but just hasn’t used it yet?

2Roronoa Zoro Might Have Been The First Straw Hat To Use Haki

Roronoa Zoro is the resident swordsman of the Straw Hat Pirates and is second only to Luffy when it comes to strength. Like his captain, he also possesses the power to use all three types of Haki. Given his goal of becoming the World’s Strongest Swordsman, Zoro will need to master Armament, Observation, and Conqueror’s Haki if he hopes to eventually defeat Dracule Mihawk. Considering the fact that Zoro is already exceptionally skilled in the application of Armament and Conqueror’s Haki, he’s not far from his life-long goal.

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. However, by the end of their time together, Zoro was consciously able to use both Observation and Armament Haki. That said, it’s possible that he awakened these abilities much earlier. The Wano Country Arc revealed that Zoro’s Ashura technique, which was first used during the Enies Lobby Arc, stems from his latent Conqueror’s Haki. This, as well as his defeat of Daz Bones in Alabasta Kingdom, is potentially the first time that any of the Straw Hat Pirates have used Haki — an impressive feat for such a distinguished crew.

1Luffy Has Mastered The Applications Of All Three Haki Types

As one of the strongest pirates in the world of One Piece, Monkey D. Luffy is, unsurprisingly, a user of all three types of Haki. By the end of the Wano Country Arc, the captain of the Straw Hat Pirates demonstrates extreme proficiency in Armament, Observation, and Conqueror’s Haki, placing him firmly on the level of his fellow Emperors of the Sea. With his Observation Haki, Luffy can see the future itself; with his Armament Haki, Luffy can emit his power over short distances; and with his Conqueror’s Haki, Luffy can even coat his attacks with the power of a true King.

Although Monkey D. Luffy primarily learned how to use Haki under the tutelage of Silvers Rayleigh, he actually awakened it several arcs before the series’ timeskip. During the Sabaody Archipelago Arc, Duval and his pet bull Motobaro threatened Luffy, unintentionally causing the Supernova’s Conqueror’s Haki to erupt in the process. Over the course of the next two years, the Straw Hat Captain went on to master the advanced applications of each Haki type, making him one of only two One Piece characters (the other being Kaido) to demonstrate such prowess.
