Luffy is one of the most proficient Haki users that fans have seen in One Piece. Although he properly tapped into Haki only recently, Luffy has advanced this skill to an extremely high degree in a very short period of time.

In terms of using Haki, Luffy can be considered to be a genius and he is still progressing at a blistering speed when it comes to utilizing these powers. Over the many battles that he has fought in the New World, Luffy has demonstrated some of the most incredible Haki feats, however, only a handful of them can be considered to be amazing.

6Knocking Out 50,000 Fishmen

Arc: Fishman Island

One of the most incredible displays of Conqueror’s Haki that Luffy has shown in the series came in the Fishman Island arc. There, he went up against Hody and his men. Luffy was able to knock out 50,000 Fishmen in a single second using his incredible Conqueror’s Haki.

This showed the fans that Luffy’s Haki had advanced to a very high degree where he could knock out these powerful enemies quite easily. As has been clarified by Oda on many occasions, the higher the difference in power between the individuals, the greater the chance to knock them out.

5Using Ryuo To Damage Kaido From The Inside

Arc: Wano Country

In the Wano Country Arc, Luffy advanced his Haki tremendously. Before this arc, Luffy’s Armament Haki was great, however, it wasn’t all that impressive when compared to the top tiers of the world. When Luffy lost to Kaido for the first time, he realized that he had to strengthen his Haki and take it to the next level. That is precisely what he did in the Prisoner Mine in Udon, and he managed to advance his Haki to a higher grade where he could channel it inside others and deal damage from the inside out.

This grade of Haki was far better and it allowed Luffy to damage Kaido on the rooftop. When Luffy launched a powerful Red Roc, Kaido was left reeling and completely collapsed on the floor, with blood gushing out of his mouth, signifying Luffy’s incredible mastery over this Haki.

4Seeing The Future To Dodge Thunder Bagua

Arc: Wano Country

Luffy awakened the ability to see the future in the Whole Cake Island arc, however, it wasn’t until Wano that he managed to improve it to the same level as Katakuri. Luffy was able to use this power in the Udon Prison Mine as easily as Katakuri, seeing frequent futures whenever he wielded it. However, and the fight against Kaido, he took this power to the next level.

At the beginning of the fight against Kaido, Luffy was able to see the future and barely avoid a Thunder Bagua, however, he was still hit by the after-effects of the attack. When Luffy lost to him once and returned, his Haki had strengthened even further, and by this point, he was easily able to avoid a Thunder Bagua from a close range by seeing the future. This is a clear indication of the fact that Luffy’s ability to see the future has become even more refined than ever before.

3Using White Star Gun To Knock Out Kizaru

Arc: Egghead Island

When it comes to the usage of Conqueror’s Haki, Luffy has quite a lot of feats, and one of them came in the Egghead Island arc, which is currently going on in One Piece. When Luffy fought Admiral Kizaru, he was able to hold him at bay despite not being at his maximum strength.

To conclude the fight, Luffy utilized the power of Conqueror’s Haki-based technique called White Star Gun. Essentially, Luffy was spinning at a very high speed and then coated his fist in Conqueror’s Haki, connecting directly with the skull of Kizaru and knocking him out in the process. This was an incredible technique that took down a 3 billion berry man in a single blow, concussing him to a point where he couldn’t even sit up for several minutes.

2Splitting The Skies With Kaido

Arc: Wano Country

Of course, one of the greatest Conqueror’s Haki feats by Luffy came in the Wano country arc, when he managed to split the skies above Wano itself. Usually, only emperor-level characters can split the heavens with a clash of their Haki. This has been seen in the story when Shanks clashed against Whitebeard, and later, when Big Mom clashed against Kaido.

In the Onigashima War, Luffy clashed against Kaido after learning better Haki control, and this time, he managed to split the skies, signifying his ascend to the level of an Emperor of the Sea. This is, by far, one of the greatest Haki feats by Luffy.

1Doing Internal Damage With His Armament And Conqueror’s Haki With Bajrang Gun

Arc: Wano Country

The greatest Haki feat that Luffy has produced in One Piece so far is the utilization of the technique called Bajrang Gun. The scale of this technique is absolutely immense. Luffy was able to create an island-sized fist and coated it completely in Conqueror’s as well as Armament Haki. The first part of this technique in itself is a ridiculous Haki-based feat.

However, what’s even more ridiculous is the fact that Luffy used this incredible ability on Kaido and crushed his Flaming Dragon Torch with it. He then channeled Conqueror’s Haki and Armament Haki inside Kaido’s body without making contact with him, thanks to using the application of Ryuo, and completely destroyed him from the inside out. This technique did incredible damage to Kaido and completely crushed him in a single blow, making it the strongest technique that Luffy has in his arsenal right now. It is, by far, one of the greatest Haki feats not just by Luffy, but by any character in One Piece so far.
