Zyglak

The Zyglak are a reptilian race accidentally created by the Great Beings out of the remains of the process that brought the first matoran villagers to life. The Great Beings were seeking to create intelligent orginisms called Krana, but found that some of the material they used turned into Zyglak instead. Shunned by their creators and hated and feared throughout the universe, the bitter, savage Zyglak retreated to the dark places. There they wait, brooding over their fate and hating the Matoran and all who honor Mata Nui. Those who encounter them rarely survive to tell others the tale.
