Biology and appearanceEdit
Xandu had a physiology that seemed to incorporate both humanoid and bat characteristics. They had a large head with fanged mouth, six eyes, and large protruding ears that could pick up signals of prey from a distance. Their body appeared somewhat humanoid in that it had a torso, with two thin arm and leg appendages. From the back of the arms were two wings which provided them with the ability to fly. There were two more wing-like formations protruding from each leg. These "wings" did not appear to be critical to the xandu's ability to fly. They would snatch prey in their talons, and dash it against rocks.
During their search for an antidote to the Blue Shadow Virus, Obi-Wan Kenobi and Anakin Skywalker encountered a xandu while climbing down a cliff wall to obtain reeksa root, the key ingredient. Skywalker was able to leap from the cliff face and grab hold of one of the xandu's legs. Kenobi then grabbed the other leg and their combined weight seemed to force the xandu's descent to the canyon floor.
