The Kanohi Crast was the Mask of Repulsion. It allowed the user to repel targets for offensive or defensive purposes. The Crast-wearer can achieve limited flight by repelling the ground.

- A Toa wouldn't normally use this mask, as it repels nature itself by using its power.
- The Crast worn by Krika was created out of protosteel.
- As a side-affect of being worn by shapeshifter, whenever Krika shapeshifted, his Crast would change appearance with him.
