Medusa

In Greek mythology, Medusa is a monster described as having the face of a hideous human female, with venomous snakes for hair. Her gaze is capable of turning any to stone.

She was beheaded by Perseus, after he used a reflective mirror to force her to turn herself to stone. He used her head as a weapon against his enemies, until he placed it on a shield and gave it to the Goddess Athena as a gift.

Medusa was spooked by the Ghost in the opening round, and immediately eliminated. Someone should tell her to not lose her head about such things.
