Haki

Haki
Haki is a mysterious power that is found in every living being in the world. It is not that different from the typical senses. However, most people do not notice it or fail to awaken it. Broadly speaking, there are two types of Haki available to everyone, given the proper training; however, there is a third type that only a certain group of "chosen ones" are said to possess.[2][3] In simple terms, Haki is an ability to sense spiritual energy (Kenbunshoku), use life force (Busoshoku) and overpower enemies (Haoshoku).

Three types

 * 1) Kenbunshoku Hakié or Observation Haki
 * 2) Busoshoku Haki or Armant Haki
 * 3) Haoshoku Haki or Conquerors Haki
