Akaku

"Glancing down at the ground, he saw the icy snow...and then the raw, cold dirt underneath...and below that, a layer of rock crosscut with veins of minerals."

- Narration, BIONICLE Chronicles 1: Tale of the Toa

The Kanohi Akaku was the Mask of X-Ray Vison, also called the Mask of Vision. The Great Akaku gave its user the power to see through solid objects and substances in general. Akaku are commonly fitted with telescopic lenses to aid the user's sight.

Akaku were carved out of a mixture of Regeneration and Teleport Kanoka on Metru Nui.
