Nina is intelligent, ambitious, egotistical, sadistic short, goth-like human girl with partially spiky black hair with side-swept bangs and a bluish skin color and a tiny dark red N, representing the first letter in her name, located on her forehead. She has a few freckles under her eyes and two buck teeth, and wears black mascara and lipstick. She also has a head with a slightly skull-like shape. She also has incredibly strong metallic hands that are capable of stretching for a long distance.
