Vamprah

"You know, I have discovered a way to force a being to shapeshift and then lock him permanently into just one form. Grab me again, and you will spend eternity as a very angry frost beetle ... with a broken arm."

- Mutran to vamprah, Shadows in the Sky

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 then used Gavla, a Shadow Matoran, as his "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.
