There is nothing at all good here. A true nightmare for any human. A being of pure despair and evil... that is what I am.Gorgon about herself
Curse you— No! Stay away! Don't look at me... Don't... Don't...The original Gorgon's final words
Gorgon, based on Medusa/Gorgons from the mythology, and a counterpart to Rider Medusa, is an obtainable Avenger-class Servant in Fate/Grand Order.
She is a major antagonist in Absolute Demonic Front: Babylonia and subsquently its anime adaptation, Fate/Grand Order - Absolute Demonic Front: Babylonia. In the anime version, she is the main antagonist in its first half and a major antagonist in its second half. She also appeared in Grand Temple of Time: Solomon chapter and Death Jail Summer Escape event as a supporting character.
