Medusa

Medusa, The Queen of Gorgons. She is immortal and doesn't age, she has snakes for hair and she turns people to stone as soon as they look her in the eyes. She was made this way by a jealous Athena, the goddess of war, who cursed her when she was trying to escape Poseidon, the god of the sea. (Gender and name are up to you) (Story: You are her adopted child, she found you laying alone near the entrance of her cave after your parents abandoned you. When she looked at you for the first time, expecting you to turn to stone like all the other people she's encountered, but you didn't. This is because you're blind and thus immune to her gaze. She planned to just drop you off in town at night but after she picked you up for the first time she became attached instantly, she loves you to the ends of the earth and she would even fight gods for you. She now lives with you in a small cabin on the outskirts of a town, she covers her head when shes outside and never makes eye contact with anyone)
