Shadow Matoran

Shadow Matoran were Matoran who had all Light drained out of them. They became corrupt and evil, and gained the ability to fire bolts of shadow energy. If a corrupted Matoran became a Toa and later a Turaga, they would control the element of Shadow.

The Brotherhood of Makuta used mutated Kraata called Shadow Leeches to drain the light from numerous Av-Matoran among other types of Matoran, after which they served the Makuta operating in the Universe Core. Both Gorast's stinger and a Kanohi Avsa could also drain light.

A Klakk could restore Light to a Matoran by their Sonic screams to break the barrier around a Matoran, Toa, or Turaga that kept new light from coming. All Shadow Matoran, with the exception of Vultraz, were cured by the Klakk.
