Kanohi Tetrux is the Minionicle signature mask. It features a "M" for "Minionicle" in the face and is inspired by some classical kanohi mask, so that it feels recognizable. The mask power of the Tetrux is compressing, making things smaller while keeping it's mass. It is worn by Minionicle mascot toa Riyat, a toa of stone with a hammer.Â
