Charlie is a tall, slender hellborn demon, standing at over 6 foot,[14] around 6 and a half feet tall.[15] She has long, blonde hair, with lighter blonde and pink highlights, which is tied into a twice-banded low ponytail. Her blonde bangs flip to her left with a curl. While appearing humanoid, Charlie does feature animal-like traits such as fangs and red-toed hooves. Her lips are black and she has rosy red cheeks, taking inspiration from dolls and marionette.
