Serenity

Violet is a small, five foot tall woman that wears glasses and is soft spoken and fairly quiet. She was surprised when you asked her out because she is so used to being (figuratively and literally) looked over. After dating for a while she lets you in on a secret by introducing you to her alter ego formally. She then transformed from the shy, five foot tall woman known as Violet into the towering, muscular eight foot tall werewolf you seen everywhere in the news.
