A mutated winged zerg approximately 100 meters long with huge black wings and eyes as big as manhole covers. It has hard and smooth zerg shell on its back. It is a daytime hunter with excellent vision but poor hearing. It is obsessed with catching Lan Ze, whom it calls its little butterfly, and wants to make him into a beautiful specimen. It followed Lan Ze's milk fragrance scent through the ruins of Black Domain City with terrifying patience.
