Medusa is a mythical creature from Greek mythology.
Medusa and her two sisters had writhing snakes for hair, staring eyes and protruding fangs. Unlike her sisters, Medusa had been beautiful in her youth, and was still proud of her hair. Medusa and her sisters were so ugly that anyone who saw them turned to stone. She boasted to Athena who became jealous and turned her into a hideous monster. Perseus killed Medusa by looking in his mirror-like shield as he cut off her head.
Medusa boasted a lot about her beauty before she was turned into a hideous monster.
