Mata Nui (OU location)

Mata Nui was an island on Aqua Magna that formed on top of the Great Spirit Mata Nui's face.

History
The island of Mata Nui was formed on top of the Great Spirit Mata Nui by automatic camouflage systems in his face that activated when he fell asleep beneath the waves of Aqua Magna.

The Legion Makuta and its allies pursued Ynot to the island of Mata Nui when he betrayed them by allying himself with Zev Raregroove. Ynot escaped from his enemies by appearing to blow himself up, but in reality he had just dispersed his essence, which travelled back into the Matoran Universe.

The island of Mata Nui was eventually destroyed in an unknown event.
