The top of the armour is decorated intricately with two snakes heads' meeting as each one arcs its back. She has a sand-green head with lime-green eyes with, dark-green lips, and fangs. Dark-green shading surrounds her eyes. She has a unique light-green hairpiece made to appear as if her hair consists of snakes.
