Nivawk

Nivawk is a Rahi from the Bionicle storyline of 2004.

Nivawk is a large bird which is Turaga Dume's (The imposter, who is Makuta). Dume can understand Nivawk's language, which Dume had learned many centuries (maybe more).

In Bionicle 2: Mystery of Metru Nui, Nivawk served as a spy for Imposter Dume on the Toa Metru. Later, Makuta fused Nivawk, Nidhiki, and Krekka with himself to create Ultimate Dume to fight Vakama.
