"Eliminator"

Eliminator worked as a troubleshooter, if a Dark Hunter should fail a mission, Eliminator would hunt down and kill the Hunter and take over the mission himself. As a result, he was hated by all the other Hunters.

History
Back when Nidhiki and Krekka were operating in Metru Nui, it was Eliminator's job to kill the Toa that the false Dume sent out of the city on false missions. He is known to have killed Toa Mangai Naho and the four Toa of Ice on the team, not to mention Kodan, a Po-Matoran chronicler, whilst they were trying to seal off the gates to Metru Nui. All that was found was a Kanohi Kakama by one of the gates, suggesting it belonged to one of the Toa Mangai, or Kodan.

Powers and abilities
He had four Kanoka Disk Launchers mounted on his back, and could harness and combine the powers of loaded disks and fire them like lightning from his talons. He was fast for his size, and it seemed he could gather shadows around him and could easily hide in low-light.
