Mata Nui (Being)

Mata Nui is the Great Spirit.

History
In the ancient past, the Great Spirit Mata Nui was sent by the even more powerful Great Beings to care for all life. He came to the Matoran people and gave them the Virtues of Unity, Duty, and Destiny. In this time, Makuta and his Brotherhood were some of Mata Nui's closest allies.

But Makuta became jealous of Mata Nui's status among the Matoran, and so hatched a dark plan. Invoking some unknown ceremony, Makuta placed Mata Nui into a deep slumber and tried to make the Matoran forget their Great Sprit and become their savior in his place, this event is known as the Great Cataclysm. As a result, Mata Nui can no longer maintain the universe as he once could, and the world has been decaying ever since. It has also been discovered that Mata Nui is in fact dying from the attack, and if he dies the universe would die with him.

But Mata Nui did see the attack coming, and manipulated events to make sure things could be made right. When new Toa Metru were about to be chosen by Toa Lhikan shortly before the Cataclysm, Makuta wished to influence the choices to his advantage. Knowing this, Mata Nui and his Order falsified prophesies regarding the identities of the new Toa. Makuta believed these prophesies, and influenced Lhikan to choose others to become the new Toa. But as these "others" were fake to begin with, the ones that Makuta influenced Lhikan to choose were in fact the true destined Toa Metru.

It has only recently been discovered that Mata Nui is dying. The Toa Nuva have been sent to Voya Nui to find the Ignika Mask of Life that could heal Mata Nui. Six Matoran followed them determined to help, and were transformed into the Toa Inika. Now both teams are racing against a group of thugs called Piraka to claim the mask before the universe dies.
