Mask of Light and Shadow

"Then a huge head rose from the steaming mercury. Makuta? No, it wasn't the dark one — at least not completely. It was the merged face of Takanuva and Makuta — half Mask of Light, half Mask of Shadows."

- Narration, BIONICLE: Mask of Light (book)

The Great Mask of Light and Shadow was a Kanohi that gave its user all the powers of the Avohkii and the Kraahkan. The Mask of Light and Shadow was created along with Takutanuva after Takanuva and Teridax fell into Energized Protodermis. When he was crushed, the mask split back into the Avohkii and the Kraahkan as Takutanuva also split back into Takanuva and Teridax.

Powers
Since the Great Mask of Light and Shadow was created from the Avohkii and the Kraahkan, it possessed all of the powers of both masks. As such, while it did gave its user the powers of Light and Shadow, it did not boost any preexisting Light and Shadow powers of its user. Additionally, it also gave its user the power to sense the moral light and darkness in others.

Known Wearers

 * Takutanuva - Formerly; now unmerged.

Trivia
