Haki

Haki is a mysterious power found in the world of "One Piece" that allows individuals to sense, strengthen, and even bypass defenses. There are three main types: Observation Haki, which enhances perception and allows sensing others’ intentions; Armament Haki, which hardens the user’s body or objects, granting offensive and defensive strength; and King’s Haki, a rare form that grants the ability to overpower others’ Haki and even incapacitate those with strong willpower. Haki is essential for combat beyond physical abilities, serving as a spiritual and mental force that complements fighting skills and can be developed with training.
