The Toa have acquired new armor; new tools, new powers, and a new name: Toa Nuva. But these new abilities do not mean that their mission is finished. They must still defeat Makuta. To do this, they will need to find six new masks. Known as the Kanohi Nuva, these are the most powerful of all the Masks of Power. The quest will not be easy. Makuta and his forces will try to stop them at every turn, but the Toa Muva must succeed if they are to save the island of Mata Nui.
