Tzitzi-Ya-Ku is a medium-sized reptile Wyvern of navy blue coloration. It has long, powerful back legs, and muscular forelegs complete with three claws for grasping prey. Perhaps its most unique feature is the pair of retractable fins that line either side of its head, which are bright and vividly colorful in appearance. Its back is lined with a row of short spines, and it has wide sturdy feet.
