Xamsters were a species of sentient reptiles who hailed from the Outer Rim planet Xagobah. Xamsters were characterized by their large ears, red or green eyes, and bicuspid beaks. Their scaly skin ranged in color from yellow to purple and sported several spiky crests. The reptiles stood slightly over one meter tall on two short legs with splay-toed feet. They had formidable claws and fangs. Their brains were capable of quickly and efficiently processing sensory input.
