"Krika triggered his mask power. The Kanohi Crast, or Mask of Repulsion, sent Gorast hurtling away from him at high speed. She smashed into a nearby stalactite with a sickening thud and hit the mud, dazed."
— Narrator, Swamp of Secrets
|Title||Mask of Repulsion|
The Kanohi Crast is the Mask of Repulsion. It allows its user to repel other objects for offense or defense; the target cannot touch the user and is flung away with considerable force. The user can also achieve limited flight by repelling the ground. This power cannot be used on more than one target at a time.
- Toa would not normally wear this mask because they generally regarded its power to repel nature itself as immoral.
