|Mask of Diminishment|
|Power(s)||Allows user to reduce in size|
The Kanohi Pehkui was the Mask of Diminishment. It granted its user the ability to compress their form in order to reduce their size. A user of this mask could shrink down to a minimum size of approximetely six inches.
In addition, while in their shrunken state, the user would retain the same amount of strength and power capacity.
- The Pehkui that Norik wore was in the shape of a Kanohi Kiril. This was primarily due to the fact that his set was originally intended to be Toa Dume. However, since Norik was released instead, it was also due to the fact that he honored a past hero with the shape of his mask. This past hero was not Toa Dume, rather another Kiril-Wearer.
- The picture used above is not a picture of the Pehkui's actual form as that remains unknown due to its only release being in the shape of a Kiril.
- The Standard Kanohi Pehkui would usually be made from a Shrink Kanoka on Metru Nui.
