Zarglak are a very hostile species with sharp claws, teeth, and arm spikes. They will attack any foreigner, toa, or matoran with no mercy. Zarglak are known for their extreme agility and strength and are usually not very bright. They speak their own language and can understand matoran but can't speak it. A large population of this species are located on the small island of Nua-Fe where they seem to live on the southern side of the great mountain range. There have been recent Zarglak attacks on the matoran villages in the northern region of Nua-Fe with no reason, but seem to be looking for something. Some think that someone is ordering them to attack but who that someone is, is unknown.
