Jude is the typical idealistic hero. He was born in the traquil village of Ciel with his mother Ethelda. Eventually, as the Brionac forces take the city in an effort to claim a missing ARM, Jude, along with Arnaud Vasquez wind up liberating the captured Gene Driver, Yulie Athreide. Unfortunately, Jude follows up this heroic rescue by activating the "Shapeshifter" arm, when then promptly destroys Ciel, which he then discovers is an isolated orbital bio-dome and not a real village at all!
