Shirley had been inspired by the famous female outlaw Belle Starr and a mixture of Disney villains like Vanessa (Ursula), Maleficent, Cruella Deville, and Madame Medusa. She first appeared in my mind as a mean, tempered old woman in one of my dreams, but then I thought she would be defeated too easily if she came out like that, so I had her changed into a woman in her 30s. She is manipulative and seductive around men who become spellbound by a pretty face, making it the perfect opportunity to carry out her dastardly deeds in secret.
