The KanohiAki was the Great Mask of Valor. It gave its user the powers of Shielding, Speed, and Strength. The mask powers could be activated individually or simultaneously by the user. An Aki can be formed by merging a Hau, Pakari, and Kakama together. The Aki appeared as a Great golden-colored Hau. If an Aki were taken off of its Toa Kaita, it would exist as long as the Kaita existed. Only Toa Kaita could form Great Aki. However, it was not possible to create a Noble Aki.
