Cray

クレイ

He served as Father Cornello's right-hand man and was a devout follower of his religion. Shortly after Ed and Al arrived in Lior, Cornello informed Cray that Ed was actually a State Alchemist and was likely in Lior for reconnaissance. As a result, Cornello ordered Cray to eliminate the Elrics in the name of their god, but he failed when a shot intended to sever Alphonse's head only revealed his empty armor. During the siege of Lior, Cray was devoured by Gluttony after he went looking for Cornello and encountered the Homunculi instead.
Cray's skeleton can be seen in Gluttony's stomach near the end of chapter 50.
