Madam Satan was originally a mortal woman named Tyra. When she found out that her fiance's parents didn't approve of her impending marriage, she murdered them in cold blood. As they were dying, they managed to tell their son who had done the deed. Naturally, the fiance wasn't too terribly happy to hear that, and he wound up killing Tyra. The murderess went to hell, where she became a loyal servant to Satan himself. Her job was to seduce men into losing their souls. Her powers included hypnotic power over men and the ability to kill with a kiss.
