Undead Dragons are minibosses found in the Valley of the Drakes and Painted World of Ariamis in Dark Souls. They are the anterior remains of what was once a true dragon. They retain some of their original characteristics, but are in an advanced state of decomposition. They have no eyes and their wings prove useless. In addition to using bite and claw attacks, Undead Dragons also possess a toxic breath attack. It's unclear exactly why these dragons are undead, as the Curse of the Undead normally affects humans only. They may be the only modern "survivors" of the war waged against the Everlasting Dragons, possibly reanimated unintentionally by Nito's deadly plague or kept "alive" by the Dragon race's inborn vitality.
