Toa Nui

The Toa Nui is a being of almost limitless power, to the point that even the great being made it physically impossible for the Toa to activate this form. In my take of this being of legend, the six Toa Mata have fused together to become the ultimate form of Kaita. Their armor turning mostly light gray to represent the elemental shift from the six primary elements of their universe, to that or Protodermis. Now capable of shaping the universe, they are able to bring life wherever they go, grow islands with a wave of their hands. Wearing the mask of unity, allowing them to obtain this form, forged by Artakha himself. Before their fusion, the Toa Mata were gifted the mask of unity split into six, and when all pieces were activated they would become the Toa Nui. Toa Nui is a pacifist due to the melding of the minds of the Toa Mata. They know they are far too powerful to fight, and to do so would cause untold damage, so the Toa Nui only chooses to help the people of the Matoran Universe.
