As a child, Christy was kidnapped by a demon working for the Triad and it is unknown exactly what happened to her during that time, although somehow the Triad brainwashed her and reversed her sense of good and evil. Christy believed that evil was good and good was evil. She received her witch powers from her grandmother, and she was tricked into using them for evil. Christy is a telepath and a firestarter. Her younger sister, Billie, a good witch, began searching for Christy when she learned that it was demons who kidnapped her. When Billie found her, Christy was scared and confused, and tried to fight through the brainwashing the demons had performed on her. She did not want to do what the demons had told her to. Unfortunately, she was kidnapped again, and it appears that during that time the demons completed the brainwashing which made Christy give in to evil, although she always truly believed she was acting for the greater good. She believed it was her destiny to destroy the Charmed Ones, and that she must stop at nothing to do it, and that it was the most important thing.
