Avenger-class Servant seen in Fate/Grand Order, first seen during the Russia Lostbelt. A composer who was the target of accusations concerning the death of Mozart, although there is no actual evidence of murder. Thus, Salieri is classified as an Innocent Monster. He doesn't call himself 'Salieri', but rather the 'Man in Grey' since this Servant is a personification of the concept of 'Mozart's murderer', a supposedly jealous man who took away God's gift to the world of music.
