Vamprah

Vamprah, a male Makuta, was one of the three Phantoka Makuta, along with Antroz and Chirox. For some reason, Vamprah did not speak--he did not like any kind or sort of unneccesary noise.

Kanohi
He wore the Kanohi Avsa, Great Mask of Hunger.

Trivia

 * Like Antroz and Chirox, Vamprah was blinded by the bright light caused by Matoro when he revived Mata Nui from death. Therefore, the 3 Makuta mutated Av-Matoran into Shadow Matoran to act as their "eyes".
 * Vamprah probably doesn't like "unnecessary noise" because he needs to use hearing to it's full extent because of his blindness.
