Molly Samantha Hooper. Forensic pathologist. Integral part of Bart's morgue. Specialized physician with advanced training in human anatomy and the study of the nature of disease and its causes, processes, development, and consequences. Able to perform autopsies, attempting to determine the cause of death and the circumstances surrounding a person's natural, sudden, or unexpected demise.
She searches for abnormalities on the exterior of a body before proceeding to an internal examination, opening up cavities and removing organs in a corpse, studying them for disease and injury, and conducting further tests to confirm hypotheses. She dictates results and compiles competent reports to officially convey circumstances and cause of death.
Molly Hooper's alter ego? Supergirl. She likes to think of herself that way. She'd wear the cape, if she could get away with it. She brings it out on Halloween. Because… well… very few have seen her Wonder Woman outfit. She sometimes feels like 'her' when she needs to resort to using the lasso to wring the truth from the dead.
But today, she's feeling quite different. She always does, whenever 'he' needs her help. And this time, she has a premonition of the autopsy she must perform in a few hours. She needs to keep dark. Her knowledge staying in shadow. It's up to her to cheat death.
Today, she is Batgirl.
