- "Shiny, shiny..."
In "Secrets", it is revealed that Margaret Sorrow was afflicted with a mental disorder called Kleptomania; a compulsive need to steal. Eventually, she was caught and sentenced to ten years in Blackgate Penitentiary. She was able to reduce her sentence to two years when she volunteered for an experiment aimed at removing criminal tendencies from the subjects' minds. During the treatments by Joe Braxton and Dr. Bethanie Ravencroft, Maggie made friends with fellow prisoner and volunteer, Lunkhead. Eventually, the experiment seemed to work and Maggie's kleptomania was gone. The people behind the experiment gave her a new name, new face, and a new chance at life. Now calling herself "Cassie", Maggie got a job as a receptionist for the very psychologist that had performed the experiment on her. However an alternate personality emerged:Magpie. Magpie erased Joe Braxton's mind and kidnapped Bethanie Ravencroft. However she was stopped by Batman. In "Attraction" Batman began visiting her. After seeing him with Katana she flew into a jealous rage, manipulating Lunkhead into freeing her. Magpie went on a rampage, leaving Batman bat shaped piles of jewels. She captured Katana and buried her alive. Magpie attempted to kill Batman but was stopped by Batman and a freed Katana. In "Reckoning" she was freed along with Professor Pyg, Mr. Toad, Cypher, Phosphorus Rex, and Tobias Whale. Magpie battled against Phosporus Rex only to be controlled by Cypher. Magpie was last seen fighting Professor Pyg.
During the day she is a perfectly normal-looking young woman named Cassie with short cropped hair and grey eyes. She wears a black sleeveless shirt and a beige knee-length skirt when working as a receptionist. At night as Magpie she wears a white, shoulder length wig and black make-up around her eyes. She also sports a black leather outfit with feathery wing-like ornaments on her shoulders and wears black thigh-high heeled leather boots. Her fingernails can sprout into long razor sharp talons lined with the nerve poison curare, which she uses as her primary weapons. She is an extremely quick and agile fighter, easily keeping up with Batman. The experiments on her mind had the side effect of making her immune to pain, so she is much more durable than she appears and is able to ignore most injuries. She retains her original kleptomania and can't resist taking things that shine and sparkle much like her namesake.
