Medusa

Medusa was one of three gorgons that arrived on Earth during Humanity's early history.

She was the better known of the three and was often depicted as being a beautiful women with snakes for hair(though this was dramatized). Like all gorgons, she was noted for having the power to turn anyone who looked at her to stone. In a challenge, she was killed by the Greek hero Perseus. (SJA: Eye of the Gorgon)

The Medusa Cascade may be named after Medusa.

The Medusa was also in the land of fiction. (DW: The Mind Robber)
