|Title||Mask of Wisdom|
The Kanohi Rua was the Great Mask of Wisdom. It gave its user the powers of Levitation, Water Breathing, and X-Ray Vision. A Rua can be formed by merging a Miru, Kaukau, and Akaku together. The powers could be activated separately or in combination. The mask appeared as either a silver Kanohi Miru or as a silver Kanohi Hau. If the Rua were to be taken off of its Toa Kaita user, it would continue to stay together for as long as the Kaita existed.
In 2001, a chrome-colored Hau-shaped Rua was included in the Power Pack.
- It is not possible to create a Noble Kanohi Rua.
