Lady is a succubus who can change forms into anything she pleases, but typically makes herself look like a woman in her 30s/40s with long blonde hair and pink eyes. She is 6ft tall in her human form, though her frequent wearing of heels makes her taller. She often wears elaborate gold jewellery with short or revealing dresses.

In her demon form, she is often 9ft tall or larger, with four arms, four eyes, four breasts, and four lbat-like wings. She has mandibles extending from the sides of her mouth, sharp talons for feet, and has a long whip-like tail. In this form she rarely wears clothing, instead being garbed in even more elaborate adornments as a status symbol to show she doesn't have to fight.

Her 'true' form is much larger and far less 'human' in appearance. She can be as tall as a building, with more teeth, arms, and wings. Her hair turns darker and with a more fur-like consistency.

Lady can be quite manipulative and cunning when she wants something and usually acts rather childish and selfish. Often she'll put on a 'dumb blond' act to make her seem more vulnerable but she is far more intelligent than she lets on. She does have a caring and motherly side, as shown by her attempts at affection with her sons.
