Keras (Earth-4001)

Keras are large coral crab Rahi that lived in the ocean of Ga-Metru, and in the reefs near Ga-Wahi. They are ferocious when protecting their home and were very hostile in general. Unfortunately, they are too hostile to train, save a few tamed by Ga-Matoran during the Bohrok War.

History
The history of the Keras is the same as their mainstream counterparts.
