This article contains spoilers from the One Piece series.

Haki is one of the most important powers in the world of One Piece, and it goes without saying that in the Final Saga, its importance is greater than ever. In this segment of One Piece, Oda has made it quite clear that those with the power of Conqueror's Haki, also known as Supreme King Haki, dominate the most.

While there have been multiple powerful users of Haki over the years, not all of them are alive at this point in time. Among those who are currently fighting it out in the Great Pirate Era, only a handful can be considered to be at the top of their game when it comes to Haki.

Zoro

  • Haki Types: Armament, Observation, Conqueror's
  • Haki Advancement: Conqueror's

The swordsman of the Straw Hat Pirates, Zoro is a great user of Haki as well. He has access to all three types of Haki, with his specialty being Armament Haki, as confirmed by Oda himself.

Zoro also has access to Advanced Conqueror's Haki, although he doesn't know how to control it yet, which means that his Haki is quite weak at this point in time. With time, Zoro will certainly strengthen his Haki even further and reach newer levels.

Yamato

Among the many Haki users of One Piece, Yamato certainly stands out quite a lot. As the child of Kaido, Yamato has access to all three types of Haki. It is not a surprise to know that Yamato has fully mastered all the Haki types, and that their control over Conqueror's Haki Infusion is quite immense.

Yamato was able to deal deadly injuries to Kaido with their Haki, and that goes to show their immense mastery over it.

Dracule Mihawk

The world's strongest swordsman, Dracule Mihawk is a skilled user of Haki. Given that he does not possess any Devil Fruit power, it is a given that Mihawk has very strong Haki.

Zoro already having Conqueror's Haki means that Mihawk has access to this power as well, and that he can utilize it at a very high level. The true strength of his Haki remains to be seen, which is why he cannot be placed any higher, but he most certainly has very impressive Haki.

Boa Hancock

  • Haki Types: Armament, Observation, Conqueror's
  • Haki Advancement: Armament

When it comes to the power of Haki, the Kuja are especially known to be adept at using it. Most of the Kuja are known to use powerful Haki, even those who are not powerful pirates. For one reason or another, the Kuja are born with the natural ability to manipulate Haki at a very high level.

Their leader, Hancock, possesses the strongest Haki of all, and she commands incredible control over all three types. Her specialty is Conqueror's Haki, and it shouldn't come as a surprise to the fans to know that Hancock can infuse this Haki in her powerful attacks.

Monkey D. Dragon

  • Haki Types: Armament, Observation, Conqueror's
  • Haki Advancement: Unknown

Dragon is the leader of the Revolutionary Army and that alone gives him tremendous strength. Although he is highly implied to have a Devil Fruit, fans know that he possesses strong Haki as well.

Looking at his ambition, and the fact that he is the son of Garp and the father of Luffy, both of whom are very high-level Haki users, means that Dragon has Conqueror's Haki, and it shouldn't come as a surprise to the fans to see him manipulate this Haki at a very high level. He can be one of the strongest users of Conqueror's Haki, but until better feats are provided, he cannot be placed any higher.

Loki

  • Haki Types: Armament, Observation, Conqueror's
  • Haki Advancement: Conqueror's

Among the new characters introduced in One Piece in the Final Saga, Loki certainly stands out as one of the strongest. He is said to be a calamity strong enough to destroy the entire world. Loki has only ever been stopped by one person, and that is Shanks.

Fans know very well that Loki's powers are absolutely immense, and he himself confirmed recently that he can manipulate Conqueror's Haki at a very high level, enough to counter the immortality of the Holy Knights. His full Haki potential remains to be seen, but if his title of the Accursed Prince, and the fact that he can destroy the world are anything to take into consideration, he is likely very overpowered when it comes to Haki usage.

Monkey D. Luffy

  • Haki Types: Armament, Observation, Conqueror's
  • Haki Advancement: All Three

The protagonist of the series, Luffy has greatly strengthened his Haki over the years. When he was training, his Haki was quite weak. But by putting himself through a plethora of incredibly difficult battles Luffy has strengthened his Haki tremendously.

Right now, it can be said that Luffy's Haki is at a very high level. He can manipulate the advanced forms of all three types of Haki with room still to grow.

Garp/Scopper Gaban/Rayleigh

  • Haki Types: Armament, Observation, Conqueror's
  • Haki Advancement: All Three (Gaban)

Nobody manipulates Haki in the One Piece world quite like the elites of the previous era. The old men of One Piece are specifically highlighted by Oda to be around the same level. These include Garp, Scopper Gaban, and of course Silvers Rayleigh.

All three of them are relative in terms of strength and all of them rely on Haki in combat as their primary power source. All three of them utilize Conqueror's Haki on a very high level and fans have already seen a glimpse of their tremendous skill. Given that all of them are relative to Roger in terms of power, it might make sense to place their Haki mastery on the same level as Roger himself.

Shanks

  • Haki Types: Armament, Observation, Conqueror's
  • Haki Advancement: All Three

In the current era, it goes without saying that among the mortals of the One Piece world, Shanks has the best Haki. He is a user of all three types, but his control over Conqueror's Haki is extremely incredible.

Oda has also given Shanks some very rare Haki applications that no other character has shown so far. It goes without saying that his Haki is monstrously powerful, and he is the strongest when it comes to utilizing it among the pirates.

Imu

The overall strongest Haki in the Final Saga of One Piece belongs to Imu. Imu is a relic of the old era, but he still stands on top as the strongest.

Imu beat Joy Boy long ago, and a glimpse of their Haki was given to the fans in Elbaf, where it truly proved to be overpowered. Imu's full extent of Haki remains unclear right now, but it is already quite evident that they possess Haki that rivals Joy Boy.
