Vamprah

Vamprah, a male Makuta, was one of the Phantoka Makuta that tried to conquer Karda Nui, along with Antroz and Chirox. For some reason, Vamprah didn't speak--he didn't like any kind of unneccesary noise. He, along with Chirox and Antroz, was blinded by the light from Matoro, when he used the Ignika to save Mata Nui's life. Vamprah made Gavla, an Av-Matoran evil, by sucking all her light. Then, Gavla began to serve as the blind Makuta's "eyes".

Vamprah was the true hunter among the Makuta, who delighted in silently stalking his prey. Even his allies were uncomfortable around him. Thanks to his mask power and his own experiments, he literally fed on the hopes and dreams of others.

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

Trivia

 * Because of his mask power, Vamprah does not need Shadow Leeches to drain the light out of Matoran.
 * Vamprah was derived from "vampire".
