Volta is a short woman with tiny features. Under her baggy clothes, she is very thin. She has curly, reddish-brown hair that pokes out from beneath her hat, and her skin is a sickly greyish color. Among her most notable features, she has a sharp snaggle-tooth sticking up from her bottom lip, as well as a lazy right eye that is completely white in color, appearing to be blind. Her left eye is a tawny brown color.
She wears a large black robe with a white turtleneck and a white cornette hat.
