Vamprah

Vamprah, a male Makuta, is one of the Phantoka Makuta that try to conquer Karda Nui, along with Antroz and Chirox. For some reason, Vamprah does not speak--he doesn't like any kind or sort 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 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.

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.
 * As Matoro was reviving Mata Nui from death, Vamprah was there and saw it all happen.
