Character appearing in Fate/Grand Order. He first appeared as an NPC during the Okeanos before being released as a Saber-class Servant during the 5th anniversary. A Greek mythological hero who was the leader of the Argonauts, and was married to Medea.
It should be noted that Fate's version of Jason is particularly abusive and cowardly, especially towards Medea, though he considers Heracles as his best friend. In combat, he directs Medea lily, Atalanta, and Heracles to attack for him on his behalf.
