Medusa is a Greek mythological figure described as a winged human female with living venomous snakes in place of hair. Those who gazed upon her face would turn to stone. With her older sisters Stheno and Euryale they made up the three Gorgon Sisters who inhabited the Shapeless Isle. She came into existence thanks to the thoughts and prayers of humans who desired a perfect goddess but she was cursed for her beauty and turned into a monster hated by all. She is thus not a Heroic Spirit but a monster closer to a Divine Spirit. Due to her nature she can manifest through different aspects depending on which disposition is predominant more or less monstrous In Fate/Stay Night In Fate/Stay Night: Heavens Feel In Fate/Grand Order First Order In Fate/Grand Order: Absolute Demonic Front Babylonia
