Medusa

Medusa is a Rider-class Servant in the Fate franchise, based on the Gorgon of Greek mythology. In Fate/stay night and Fate/hollow ataraxia, she is summoned as Sakura Matou's Servant, though control may be transferred to Shinji.

Medusa as the Rider-class Servant

Reserved, loyal, and protective of Sakura, Medusa fears the monstrous identity associated with her past. She enjoys ordinary reading and domestic peace when circumstances allow.

Mystic Eyes, Bellerophon, and loyalty to Sakura

Medusa uses superhuman speed, the chained dagger Nameless Dagger, mystic eyes that petrify targets, and the Noble Phantasm Bellerophon. Her relationship with Sakura distinguishes this adult Rider form from younger or fully monstrous Gorgon variants.
