Kewa were large bird Rahi that could be found in three varying breeds. Gukko birds were extremely swift, and generally peaceful, though they would fight if threatened. Le-Matoran often tamed Gukko for their Gukko Force. Rahaga Kualus insisted that "Gukko" is the incorrect name for the species, and may even be an insult in their language. Two of the breeds were previously called Kahu and "Kewa."
