In her guise as Mary Wardwell, Madam Satan appears to be a Caucasian female in her mid-forties, tall, with dark hair and blue eyes. Her true demonic appearance consists of green skin, skull-studded eyes, no nose, and razor sharp teeth. Madame Satan is a cold, sadistic and deeply determined individual who is extremely loyal to the Dark Lord and is completely relentless and guiltless over any action she commits. She's as ancient and powerful than most witches.
