Luffy's unaware Conquerors Haki at Marineford [One Piece]

Haoshoku Haki (覇王色の覇気) is a rare form of Haki that allows the user to exert their own willpower over others. Unlike the other two types of Haki, this type cannot be awakened through training and only one in a million people are born with this ability.

It is said that whoever possesses this type of Haki has the qualities of a king, and thus are known as Supreme Rulers (覇王, Haō)

Haoshoku Haki is considered an extremely dangerous threat and a highly valuable asset by powerful groups such as the Four Emperors, Marines, Seven Warlords of the Sea and Five Elders.
Also called: Conqueror's Haki and Kings Haki.
