Kalju

The kanohi Kalju is the Mask of Reversal. The great version can reverse any transformation, including energized protodermis, hordika venom, pit mutagen, and a mask or mutation. Whether or not the the reversal is temporary or permanant, and how long it lasts if it is temporary, depends on the mental strength of the user. The noble can only reverse transformation temporaily and can not reverse energized protodermis. Neither can be used to reverse transformed objects.

Trivia

 * Toa would consider this mask immoral; they veiw it as snuffing out a being original destiny and replacing it with a differant one.
