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.

Vamprah is the true hunter among the Makuta, who delights in silently stalking his prey. Even his allies are uncomfortable around him. Thanks to his mask power and his own experiments, he now literally feeds on the hopes and dreams of others.

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.
 * Where Vamprah flies, he spreads shadows.
