The shield flared to life around Kopaka. Stone rained down upon it and shattered to harmless fragments, while the ancient energies of the Kanohi kept the Toa of Ice from harm.

Nuva Mask of Shielding
Power(s)Gave user(s) enhanced Shielding
Notable Wearer(s)The Toa Nuva (except Tahu)
PronunciationHOW NOO-vah

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, attacks such as molecular disruption could disrupt the shield. The only beings able to activate this mask's power 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. Later on, Tahu attempted to deflect Panrahk's fragmentation beam, only to have it blast him backward through a stone wall.
