Jasper has a long neck signature of his race. He has a thin, yet muscular body. His curtained purple hair messily frames the sides of his face.

He wears a scarf resembling a coiled snake that completely obscures his neck because of his insecurities over it, and a camouflage long-sleeve shirt with beige-colored pants tied by a sash and tucked into boots.
