"Seeker"

Seeker was once a part of the Brotherhood of Makuta and was assigned to to guard the Kanohi Avohkii after the Brotherhood of Makuta stole it from its creators. He gained a desire to own the Mask himself, but was beaten to stealing it by the Toa Hagah. He has since sought out the Rahaga in search of the Mask of Light. So far, he has been unsuccessful, since the Rahaga gave the mask to the Toa Hordika, and they eventually managed to get it to Takanuva who now dons the mask.

Seeker's primary weapon was his staff, which could weaken an opponent by delivering seismic shocks, and then sending an earth tremor, knocking the already-dazed foe out.
