Conqueror's Haki is an incredible ability that exists in the One Piece world among only a select few people who are born with it. These are people destined for achieving great things, and having great leadership qualities. Conqueror's Haki is present only within one in a million people and, even among those, only a few can infuse this power. According to Kaido, only a handful of the strongest know how to infuse Conqueror's Haki, and those who do gain the ability to rise to the very top of the era.

These One Piece characters likely awakened their Devil Fruit powers, unbeknownst to the fans.

Among the many users of Conqueror's Haki Infusion, there are some swordsmen who have utilized this power in conjunction with their incredible swordplay. These are some of the very strongest fighters in the One Piece world who have made a significant mark on their respective eras.

5 Roronoa Zoro

Conqueror's Haki Infusion Used In Chapter 1033

Roronoa Zoro is an incredibly powerful swordsman in One Piece. He's one of the characters who can be considered to be a true swordsman and not just someone equipped with the sword but a user of a different fighting style. Zoro primarily utilizes swords in combat and he has his infamous Three Sword Style to help him defeat his enemies.

When Zoro makes use of Conqueror's Infusion, he relies on what is known as King Of Hell Three Sword Style. Essentially, Zoro infuses his swords with Armament and Conqueror's Haki and this is indicated by the green flame-like aura they start emitting. At times, they can also exude Conqueror's Haki sparks which fans have seen on many occasions in the story. Zoro first utilized this power against King in Wano and he certainly did incredibly well in that fight, managing to finish him off with a powerful technique known as 103 Mercies Dragon Damnation. Later on, in Egghead, he used this power once again in his fight against Lucci and this fight is currently still ongoing.

4 Silvers Rayleigh

Conqueror's Haki Infusion Used In Chapter 1059

The former right-hand man of the Pirate King, the Dark King Silvers Rayleigh is an incredibly powerful swordsman as well. He is a user of all three Haki types and given that he doesn't have any Devil Fruit, his Haki is, naturally, incredibly overpowered. Rayleigh is a user of Conqueror's Haki Infusion and he showed this when he confronted Blackbeard in One Piece chapter 1059. Just by a mere showing, Blackbeard decided that it was not worth fighting him.

Sadly, Rayleigh is beyond his prime right now and he himself confirmed that he wouldn't be able to defeat Blackbeard as he is. However, in his prime, he would have been much stronger and likely could have been placed higher up this list as well.

3 Kozuki Oden

Conqueror's Haki Infusion Used In Chapter 970

Kozuki Oden is a character who was capable of using all three Haki types. While many believe him to be not a user of Conqueror's Haki Infusion, he was absolutely a tremendous user of this skill and he showcased it when he managed to scar Kaido across his gut. This is indicated by the fact that Kaido immediately realized that Zoro made use of Conqueror's Haki when he scarred him across his chest.

The Admirals have powerful Haki, making them some of the top fighters in the world of One Piece.

This reminded him of how Oden used a similar ability to scar him, only on a much greater scale. Oden also wielded Enma, which is what allowed Zoro to bring out his Conqueror's Haki in the first place. Oden was an incredibly skilled user of Conqueror's Haki, such that Zoro, even after pushing himself to his very best, could not match the level at which he used his Haki. According to Zoro, Oden could wield Enma as if it were a feather and, for Zoro, it would kill him within a few minutes. Furthermore, Kaido himself considered Oden to be a pirate in the same league as the likes of Whitebeard and Rocks, and that in itself is confirmation that he's one of the strongest swordsmen as well as an incredibly amazing user of Conqueror's Haki in the One Piece world.

2 Shanks

Conqueror's Haki Infusion Used In Chapter 1079

Shanks is widely believed to be a master of Conqueror's Haki and it is no surprise to the fans that he can utilize Conqueror's Haki Infusion as well. When he clashed against Eustass Kid, Shanks infused his sword with Conqueror's Haki and utilized a technique called Divine Departure, or, Kamusari. This is a technique that he inherited from his mentor, Roger, the former Pirate King. This technique was performed at such a level by Shanks that it was able to knock out both Kid and Killer in the same attack.

This feat is incredibly impressive, especially since Kid had a bounty of 3 billion berries and Killer was no pushover either. Shanks is certainly one of the strongest users of Conqueror's Haki in One Piece, however, it must be remembered that when it comes to swordsmanship, Shanks doesn't rely on just that in combat and his fighting style isn't clear just yet.

1 Gol D. Roger

Conqueror's Haki Infusion Used In Chapter 966

Roger is another powerful Conqueror's Haki user who also used his sword in combat at times. Fans have seen him rely on his Supreme Grade Weapon, called Ace, in combat on many occasions. When Roger clashed against Oden for the first time, he made use of Conqueror's Haki with a technique known as Divine Departure, or, Kamusari. This technique was so strong that it sent Oden flying and dealt quite a significant amount of damage to him.

Later on, Roger charged his sword with Conqueror's Haki and clashed against Whitebeard, who also utilized this skill against him. These two went on to take part in an elaborate fight which ended in a draw. Given that he is the greatest conqueror in One Piece, he is also likely to have the strongest Haki, which can only be rivaled by the likes of Shanks at the moment.
