Kualus

Kualus was the Toa Hagah of Ice before he become a Rahaga.

Rahaga
Kualus was fiercely protective of all flying Rahi, and even spoke in their language at times, adding clicks and whistles to his sentences. He taught this language to Nuju. He used his staff to summon flying creatures or warn them of danger. His boomerang spinners could latch on to a flying Rahi and bring it to him.
