Gukko

Gukko were a large species of bird Rahi. Gukko birds were extremely swift, and generally peaceful though they would fight if threatened. The Le-Matoran on Mata Nui often tamed Gukko for their Gukko Force.

Trivia

 * The word Gukko may actually have been an insult in the bird's language, as told by Rahaga Kualus.
 * The word "Gukko" was originally Kahu and Kewa. However, due to a lawsuit by Māori activists, they were changed to Gukko. Strangely enough, the actual Kewa and Kahu models were different from the present Gukko's.
