In Greek myth Bellerophon was the hero who tamed Pegasus, and Fate/stay night borrows the name for Rider Medusa's Noble Phantasm, a bridle given power by her legend. Medusa first appeared as Rider in Type-Moon's 2004 visual novel, later reaching wider audiences through the anime adaptations and Fate/Grand Order. Clips of her calling the attack circulate among Fate fans as a shorthand for a desperate, all-in strike, and the short shout is shared in edits and soundboards far beyond full episode scenes.
