Life was one of the three Legendary Powers, along withTime and Creation. The only object able to control life was the KanohiIgnika, the Legendary Mask of Life. This means that no Matoran or Turaga of Life exist. In fact, no true Toa of life exist, as Toa Ignika was merely a body created by the Kanohi Ignika, and Mata Nui's body was created by the Ignika. This element is too powerful for any Toa to use and even requires the death of the user in order to be used.
