The Chaos Harpy was unleashed by Xiang after Xing and Xang merged together to become her. This Chaos Beast had the ability to poison people by shrieking at them, which could only be cured by using a Shriekward potion. Nevertheless, the AQW hero managed to defeat the Chaos Harpy, which set Xiang off into a rage-filled tantrum.
- The Chaos Harpy is based on the mythological monster Harpy, which had a female body and the legs and wings of a bird.
- The Chaos Harpy was not summoned until the Mirror Realm chapter of the 13 Lords of Chaos Saga, which occurs just between the Thunderforge chapter and the Swordhaven chapter (although the Mirror Realm chapter is listed after the Swordhaven chapter).
