Medusa

Medusa is a gorgon, who appears in the Gorgon episode. She saves Hercules from drowing, and devolping a crush on him. She wanted to change the way she look, so she beseeches the gods for help. The only gods who answers her are Hades and Aphrodite.

Aphrodite advises her that real friends will love her for who she is, and gives her glasses that will prevent Medusa from turning people to stone. But scheming Hades has a different idea, he makes a deal with her. He will be happy to turn her human by day, but at night, she'll turn back into a gorgon and works for him. Medusa agrees, and changes into a human.

She arrived at Prometheus Academy as a new student and met Hercules and Nattie, who had her suspicions on her. At sunset, Medusa hid in the girl's bathroom and had been discovered by Nattie. When things couldn't get any worse, Hades arrived to take Medusa away to begin her work on Team Hades. Nattie realized what was going on and hated Medusa and Hades for it.

At the end of orientation, Nattie had to share a room with Medusa. As Medusa explained her reasons for turning human, Nattie felt bad about the way she treated Medusa and cut her some slack.
