Nokama

Nokama was a toa of water and one of the Toa Metru chosen by Mata Nui to save the matoran. Nokama was once a matoran who was approached by Toa Lhikan, sole protector of the city of Metru Nui, who gave her a toa stone. She later went to the Great Temple, where she met five other matoran: Vakama, Nuju, Onewa, Matau, and Whenua, and they were transformed into toa. After rescuing the matoran, Nokama and the other Toa sacrificed their toa power to awaken the matoran and became turaga.
