Voporak

Voporak was a former clan leader of Sidorak's species and Dark Hunter. Sidorak betrayed him to the Brotherhood of Makuta to gain power. Through experimental mutation, The Brotherhood transformed him into Voporak, a being sensitive to shifts in time that could locate the Vahi Mask of Time, if it ever came into existence. The Brotherhood of Makuta lent Voporak to the Dark Hunters to learn discipline.

Voporak had sensed the power of the Vahi when Toa Vakama had used it in his fight against Makuta. Voporak made his way to Metru Nui in search of the Mask of Time. He succeeded in snatching the mask for a short period of time, but Vakama got it back during a battle against the Shadowed One and Makuta. Currently, Voporak is working with "Ancient" to find the Vahi, following Toa Tahu's use of it against the Bohrok-Kal.

Powers and Abilities
Voporak gives off a temporal force field that ages any attack used against him. For instance, fire would burn out and thrown rocks would erode to dust before they can reach him. His touch ages anyone or anything if he wills to do so. He also has Rhotuka spinners that temporarily knock targets out of sync with time, leaving them a second or two behind the rest of the world. Only one weakness has ever been exploited against Voporak, which was taking away air so it could not breathe, Makuta thought of this approach during his battle with "The Shadowed One".

Trivia
