Zaethos

The Kanohi Zaethos was the Mask of Mimicry. It granted the user the capacity to duplicate the mask powers of not only his allies, but also his opponents, that were located in the immediately surrounding area. This lone Kanohi Zaethos was subsequently exposed to Energized Protodermis, at which point it transformed into a Zaethos Nuva, an enhanced version of the Great Mask of Mimicry, which now provides the user with the ability to boost the replicated mask power to Nuva levels.
