It can be divided into three types— Armament Haki, Observational Haki, and Conqueror’s Haki. The first two types can be learned with enough training, however, Conqueror’s Haki cannot be awakened with training. Only a person who is innately born with Conqueror’s Haki can use it, which makes it the rarest type of Haki in OnePiece.

UPDATED on February 18, 2022, by Suzail Ahmad:As the Wano Country arc progressed, the fans received more information about the use of Conqueror’s Haki in fights. Conqueror’s Haki can be infused in attacks, which drastically increases their power. It takes a great degree of skill to use Conqueror’s Haki in combination with attacks. Only a handful of characters have shown such mastery over Conqueror’s Haki. We have added the biggest feat of every Conqueror’s Haki user so far.

17 Luffy

The captain of the Straw Hats, Luffy unknowingly used Conqueror’s Haki during the Marineford arc. When Ace was about to be executed by the Marines, Luffy’s desperateness awakened his latent power. He used Conqueror’s Haki and knocked out the executioners, thus saving Ace. Since then, Luffy has learned to use all three types of Haki.

Biggest Feat: Luffy’s biggest feat so far is undoubtedly being able to fight against Kaido 1v1. At the beginning of the Wano Country arc, Luffy was immediately knocked out by Kaido, but currently, he can fight the “Strongest Creature in the World.”
