Niazesk

Niazesk were insect-like Rahi created by the Brotherhood of Makuta in order to keep larger Rahi in check by their venomous bites. The Makuta then spread them all across the Matoran Universe in order to do so.

Mutran took several of these Rahi to Karda Nui when the Makuta invaded it. They were mutated by the swamp water in the Swamp of Secrets and enlarged several times and their venom strengthened.
