For the chapter, see Chapter 1010.

Haoshoku Haki is a rare form of Haki that allows the user to exert their own willpower over others. This type of Haki cannot be attained through training and only one in several million people are born with this ability.[2]

It is said that whoever possesses this type of Haki has the qualities of a king,[3] and are known as Supreme Rulers (覇王, Haō?).[4]

Haoshoku Haki is considered an extremely dangerous threat and a highly valuable asset by powerful groups such as the Marine Admirals and the Four Emperors.

It was first demonstrated by Shanks, when he used it to scare off the Lord of the Coast, though it was not fully explained and revealed.[1] Later on, during a meeting with Whitebeard, he used it to knock out most of the crew,[5] which the few still standing attributed to his superior Haki.[6]

Luffy first displayed the effects of this type of Haki against Duval's bull, Motobaro, much to everyone's confusion. He displayed it again on Amazon Lily while battling Sandersonia and Marigold, knocking out a large portion of the audience observing the match. This is also the first time it is referred to by name.[7] Luffy also used it to knock out the wolves attacking him and Bon Clay in Impel Down, although he was poisoned badly by Magellan at the time and still had no control over it. Luffy exhibiting it during the Summit War of Marineford was enough for the Marine Admirals to become wary enough of him that they prioritized his elimination afterward.

After the timeskip, Luffy is proficient enough to tame monsters, as well as knock out a selected group of individuals without affecting any of the bystanders using Haoshoku Haki, displaying his new-found proficiency in the skill. Luffy was even able to use it while unconscious.[8]

It has been implied a number of times that this Haki is based on lineage. Doberman, for example, noted that Luffy possessing Haoshoku Haki made sense since he is the son of the Monkey D. Dragon, the Leader of the Revolutionary Army. It is later shown that Monkey D. Luffy, Portgas D. Ace, Charlotte Katakuri and Yamato also possess this Haki type just like their parents and grandparents (Monkey D. Garp, Roger, Big Mom and Kaidou respectively). However, not all children from the same parent are born with Haoshoku Haki, as Donquixote Doflamingo, Boa Hancock and Katakuri are the only ones among their siblings to possess it.

The shockwave-like effects of clashing Haoshoku Haki users.

It has been shown that when two users of this Haki clash, it causes a rippling or shockwave effect, cracking the air similar to the Gura Gura no Mi. This is simply referred to as a Haoshoku Clash (覇王色の衝突, Haō-shoku no Shōtotsu?, literally meaning "Supreme Ruler Color-Clash"). The shock waves from the Haoshoku Haki clash between Luffy and Chinjao were strong enough to blast people out of the coliseum arena into the water below.[9] The Haoshoku Haki clash between Luffy and Doflamingo produced shockwaves that pushed Trebol and Law's incapacitated body away from them.[10]

During a battle between Gol D. Roger and Edward Newgate, the Haoshoku Haki clash between these two legendary pirates resulted in a massive shockwave that spread across the island and nearly capsized the enormous ship, Moby Dick.[11]
