Rua Nuva

The Kanohi Nuva Rua Nuva is the Mask of Wisdom. A Rua Nuva can be formed by immersing a destined Kanohi Rua in Energized Protodermis or by merging Miru Nuva, Kaukau Nuva, and Akaku Nuva together. It would give its' user and those nearby the enhanced powers of Levitation, Water Breathing, and X-Ray Vision. The mask user(s) would be able to activate the powers separately. The only beings able to use this mask are Toa Nuva.

Bearers
The Rua Nuva is theoretically worn by the Toa Nuva Kaita Akamai Nuva, but he has never been formed. Thus, it is believed that an Aki Nuva has likely never existed in the Matoran Universe.
