A variant form of Plaga. It, too, bursts fourth from the body when the Majini takes enough damage, but unlike the
Cephalo the Duvalia bursts out of the host's upper half, leaving the Majini's entire torso hanging uselessly below. The Duvalia is covered by a hard exoskeleton to protect the fragile parasite beneath. When it gets close, however, the exoskeleton retracts enough to reveal a mouth-like protrusion, which it uses to try to swallow its enemies.
