Medusa Gorgon (メデューサ・ゴーゴン), simply known as Dr. Medusa while in the academy, was a witch, the middle of the three Gorgon Sisters, and the mother of the demon sword master, 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.
"You're horrible! Commenting on my appearance like that! I don't have to listen to this from you! It's sexual harassment!"
When acting as DWMA's nurse, Medusa presents herself as a caring and supportive member of the staff, even to the point of comforting Maka Albarn when she displayed her insecurities as a meister and showing "concern" for other students within the academy such as Soul. She was known throughout the academy for being a kind faculty member who not only treated students but also counseled them. However, as Franken Stein pointed out, Medusa herself is "full of lies" and in actuality cares little for anyone but seemingly herself. Being a scientist, she also tends to views things like a researcher to the point of using actual individuals such as her own 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 strengths, however, are 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.
