Jude is an enemy character from the prototype version of Fire Emblem: The Sacred Stones. He appears in Chapter 8 and seeks to capture Eirika. He introduces himself as Jude Rubert, one of the seven imperial generals of Grado, and Seth recognizes him as the Obsidian. A placeholder boss is used in Jude's place in the prototype, so his intended class is unknown.
Saint Jude, also known as Judas son of James and Judas (not Iscariot), was one of Jesus' twelve apostles.
