He owns a wide selection of Noble Phantasms, like the Sandals that fly through the air, the Mantle that changes the appearance of the wearer (a helmet in the myths), the bronze mirror shield that Athena gave him (equipped with radar and sonar), the snake hunting sickle Harpe (kills immortals), the bag that stores the head of monsters Kibisis (a mirror world type bounded field), and the familiar Pegasus-handling bridle from FSN, Bellerophon. He is the very person who killed FSN Rider (Medusa).
