Haki is an incredible ability that stems from the spirit of the user in One Piece. This power is found inside every individual; however, not everyone can awaken it. The strongest individuals in the One Piece world, such as the Yonko, the Marine Admirals, or even the likes of the Vice Admirals and other veteran pirates, seem to be avid users of Haki. However, there are also individuals who might not be all that strong, but still possess this ability up their sleeve.
