|Title||Mask of Hunger|
|Powers||Drains energy, Light, or positive emotions|
The Kanohi Avsa is the Mask of Hunger. It allows its user to drain light, energy, or positive emotions from a target at a distance. The user will absorb the energy removed from their target. This mask can be used to make lightless beings such as Shadow Matoran. The Kanohi Avsa automatically places a psychological barrier in its victims that keeps their light from returning, although the light drain must be complete before the barrier is set. The power scream of Klakk can reverse this by breaking the barrier.
- Vamprah used his Kanohi Avsa on Toa Nuva Kopaka to drain his energy in Realm of Fear.
- Vamprah also used his mask to drain Radiak's light, turning him into a Shadow Matoran in Shadows in the Sky.
- Gavla - Formerly; replaced with a different mask
