|Mask of Disruption|
|Power(s)||Makes target lose control of a power|
|Notable Wearer(s)||Gorast (formerly)|
The Kanohi Felnas was the Mask of Disruption. The Felnas allowed the user the ability to tamper with a foe's powers to an extent where they would backfire on the user upon physical contact.
Gorast used her Felnas on Icarax in The Final Battle to make his teleportation power backfire, causing him to be teleported everywhere at once and destroying him.
- It was not a mask Toa would wear, as they thought the power immoral.
- Her mutation gave Gorast a stinger on her mask that could drain a being's light. However, the stinger was not part of the mask.
- The Felnas worn by Gorast was created out of protosteel.
- As a side-affect of being worn by shapeshifter, whenever Gorast shapeshifted, her Felnas would change appearance with her.
