Vakama

Vakama was a toa of fire and the former leader of the Toa Metru who was chosen by the great spirit Mata Nui to save the matoran. He was once a crafter who was approached by Toa Lhikan, the sole protector of the city of Metru Nui, and given a toa stone. Vakama later traveled to the Great Temple in Ga-Metru where he met five other matoran: Nokama, Matau, Onewa, Nuju, and Whenua, where they were transformed into toa and were sworn to save the matoran. After completing their mission, Vakama and the other Toa Metru sacrificed their toa power to awaken the matoran and became turaga.
