Medusa Gorgon, simply known as Dr. Medusa while in the academy, is a witch, one of the three Gorgon Sisters, and the mother of the demon swordmaster, Crona. Formerly a nurse in the DWMA, she secretly plotted to release the Kishin from his sealing and succeeded with the assistance of her group of associates. When acting as DWMA's nurse, Medusa presents herself as a caring and supportive member of the staff. She was known throughout the academy for being a kind faculty member who not only treated students but also counseled them. However, Medusa in actuality cares little for anyone but herself. Being a scientist, she also tends to view things like a researcher to the point of using actual individuals such as her child, for experiments. In addition, she can be viewed as irredeemable, willing to manipulate anyone for her goals, and even abandon her own child after deeming them a "failure". Perhaps Medusa's greatest strength, however, is her cunning and intellect. Often enough, she forms complex plans that even the DWMA at times fails to counter and tends to learn from her own mistakes. She even feels blasphemy is part of the nature of being a Witch. However, despite these dark and manipulative traits, even Medusa can possess some love. However, she most likely cannot truly understand the concept of love. Medusa herself isn't infallible to even being subject to other emotions such as nervousness to the point of actually fidgeting. Oddly enough, despite her horrendous actions and rather odd tendencies, she finds the antics of the DWMA upper brass utterly absurd, and impossible to manage.
