Name: Sandra Lynn Livingston (possibly an alias)
Codename: Nightmare

Nightmare was being hunted by the Halls County Sheriff's Office in Texas when Phoenix Team recruited her. Prior to that, she was responsible for a series of brutal deaths and injuries, starting in her home and then tracking through a series of foster homes -- always in response to abuse, neglect, or other mistreatment (not always of herself). Headmaster Saint-Vincent and the other faculty have been working closely with her to help her develop better social relations and coping methods, with mixed results; she still tends to turn into a beast and stalk away into the forest at the back of the mansion when she gets frustrated. 

Nightmare is powerful and subtle shapeshifter, able to assume animal forms, mimic individuals, and assume a "nightmare form" that seems to be an expression of her rage. In her nightmare form she is nine feet tall, mostly humanoid but with pitch-black skin and blood-red eyes, covered in spikes, and equipped with wings, a prehensile tail tipped with a stinger capable of delivering various poisons, and clawed hands and feet that are also capable of delivering powerful bio-electric shocks. She is both stronger and tougher than ordinary flesh should be, and is capable of flying at roughly seventy miles per hour. She acts as Jade's second-in-command, but has not formally accepted the position; she just finds it encouraging that people listen to her in emergencies.
