Akaku Nuva

The Akaku Nuva was the Kanohi Nuva Mask of X-Ray Vision, created when a Kanohi Akaku was dipped in Energized Protodermis. It gave the user and those nearby the power to see through objects and illusions. They were fitted with telescopic lens to give the user(s) enhanced viewing. The only beings able to use this mask were Toa Nuva. For some reason, this mask's power cannot pierce the mist in Karda Nui.
