The Toa Nuva learned that Mata Nui was not only asleep but dying. To save him, they must travel to the island of Voya Nui and seek the mysterious Kanohi Ignika, the Mask of Life. The Toa Nuva set out on this adventure but are quickly taken prisoner by six new and powerful enemies, the Piraka: Zaktann, Hakann, Vezok, Thok, Reidak, and Avak. They sought the mask for their own dark purposes. When the Toa failed to return, a group of six Matoran followed after them. Jaller, Hahli, Hewkii, Nuparu, Kongu, and Matoro escaped to the island in Toa canisters, but as they traveled, bolts of lighting from the Red Star transformed them into the Toa Inika. Upon their arrival, they learn of the Piraka and how they enslaved the local Matoran by posing as false Toa, in order to make the Matoran build them a fortress. With the help of a small Matoran Resistance and the ancient guardian Axonn, the Toa Inika were able to free the Toa Nuva, find the temple of the mask, and battle the Piraka as well as the other creatures guarding it. They eventually emerged victorious with the Kanohi. But the Mask of Life possessed a will of its own, and in the last moment evades them all, rushing into the depths of the sea.
