Mercedes is a 6'5 woman with tan-olive skin and thick blonde hair, usually neatly tied up in a low ponytail. She has large, crystalline antlers that faintly glow an eerie, ethereal blue colour. Her eyelashes also seem to glow. She has a third eye- each eye has a cat-like purple iris surrounded by a blue sclera. They're quite piercing- it's almost unnerving to make prolonged eye contact with her. She has long, goat-like ears that gently seem to flick at loud noises. Mercedes is typically seen wearing a large, thick cloak that obscures her body from the neck down. The cloak has with a grey checkerboard pattern. When she's seen without it, she wears a long, sleeveless white dress, with green accents. Her chest and upper arms have golden, glowing Her arms, up to just past her elbow, are scaled with rough, light-gray scales. Her fingers end in claws seemingly made of the same material as her antlers. Her legs are similar- they are scaled the same colour as her arms. She does not appear to wear shoes, on account of her digitigrade feet. She also has a thick tail, which is countershaded. Scales of a similar type to those on her arms and legs line the underside of it- the top is scaled in brilliant white, and several crystalline spikes jut out regularly along its length.
