Hau Nuva

"The Mask of Shielding protected us all! It could never do that before...!"

- Tahu, Comic 8: The End of the Toa?

The Hau Nuva was the Kanohi Nuva Mask of Shielding, formed when a destined Kanohi Hau was exposed to Energized Protodermis and transformed. The Hau Nuva gave its user and those nearby the power to shield themselves from physical harm, as long as the user(s) was aware of all attacks made at them. In the event of a mental attack, however, the Hau Nuva was useless. Additionally, various attacks, such as molecular disruption, could disrupt the shield. The only beings able to activate this mask were Toa Nuva.

Example Usage
In BIONICLE: Mask of Light, Tahu Nuva used his Hau Nuva to protect Takua and himself from a wave of lava.
