Aki Nuva

The Kanohi Nuva Aki Nuva is the Mask of Valor. Aki Nuva can be formed by immersing a destined Kanohi Aki in Energized Protodermis or by merging Hau Nuva, Pakari Nuva, and Kakama Nuva together. It would give its user and those nearby the enhanced powers of Shielding, Strength, and Speed. The mask user(s) would be able to activate the powers separately. The only beings able to use this mask are Toa Nuva. This mask appeared as a Hau Nuva.

Bearer
The Aki Nuva is supposed to be worn by the Toa Nuva Kaita Akamai Nuva, but he has never been formed. Thus, an Aki Nuva has never existed.
