Antharahk

Antharahk was the official Makuta of Powai Nui.

History
Antharahk was created along with the other Makuta and joined the Brotherhood of Makuta. He seemed to be acute at creating deadly diseases and pest Rahi. Other Makuta looked down upon him for making simple microorganisms. After Miserix was overthrown he became loyal to Teridax.

After Nephix and Tetradon turned rogue, Antharahk was appointed the new Makuta of Powai Nui. However, he did not have much impact on the island's events.

Powers and Equipment
As a Makuta, Antharahk is able to create, control, and absorb the element of Shadow. He wears the Kanohi Jemena, the Mask of Replication, which allows him to create an exact duplicate of himself or another being with the same memories, personality, powers, and strengths.

Antharahk lost his right arm at some point, and in place of it he now has an axe blade. He has also adopted two extra arms, each tipped with a razor called a Pestilence Razor, although they have no disease-related powers and simply emit beams of shadow.

Personality
Antharahk is never loyal to his obligation. Ever since he was assigned to rule over Powai Nui he has done nothing to alter the island's history. It is not known what he does in his free time, although it likely involves some sort of virus. He has a list of those who have crossed him. Nobody knows what he plans to accomplish with this list, but the last being other than Antharahk to see it says it had at least 200 names. He enjoys sadistic experiments, creating creatures and then seeing how they react to the thousands of plagues he hold in bottles in his lair. Some question which he holds more interest in; seeing the results or the suffering.

Trivia

 * Antharahk's name has a resemblance to Anthrax, a deadly disease. This fits in with his plague-based powers and personality.
 * Antharahk's Pestilence Blades and his flagellum-like tail are likely his own doing.
