The island of Mata Nui was once a paradise – until the entity known as Makuta arrived, transforming it into a land of darkness and evil. The natives, called Tohunga, have waited and hoped for heroes who could conquer Makuta and save their home. Now their waiting has come to an end. Six mighty warriors, known as Toa, have arrived on Mata Nui. Each controls a force of nature – fire, air, earch, water, stone, ice. But to triumph over Makuta, they must gather the Kanohi Masks of Power, which give them greater skills, abilities, and wisdom. The more masks the collect, the more powerful the Toa become.
