Golden Kanohi

"Then there was a peal of sound, like great bells blended with laughter. Onua gasped in amazement as a new mask suddenly appeared on the face of each stone carving--a golden Kanohi, glowing with light and power. Onua carefully lifted the golden Kanohi from the carving's face and placed it on his own. He staggered back a step as waves of power blasted through him. Then he smiled. This united all the powers of the other six--only it was even stronger!"

- Narration, BIONICLE Chronicles 1: Tale of the Toa

The Golden Kanohi were six Great masks, each giving the user the powers of the Hau, Kaukau, Pakari, Miru, Kakama, and Akaku.

History
These Kanohi appeared only once, when the Toa Mata collected their Great Masks, brought them to the Kini-Nui, and placed them onto life-sized carvings of themselves.

The Toa Mata used these masks to fight and defeat Teridax, and the Bohrok swarms before finally losing them when they became Toa Nuva. Takua also once discovered a Golden Hau in the Great Mine of Onu-Wahi.

How the Golden Kanohi were created is still unknown, although it is known that they were created by Artakha.

Example Usage
In Comic 4: The Bohrok Awake, the Toa Mata all used their Golden Kanohi's Speed power to travel from Kini-Nui to Ta-Koro in moments.
