Wild Flower, voiced by Nicky Pugh. She is a young girl who died during the flooding of Tien's Landing. She is then used by the Heavenly Gate Guardian, Chai Ka, as an anchor to the world, so that he may help the Spirit Monk and safeguard a piece of the amulet. He cares greatly for Wild Flower, and protects her from harm. Ya Zhen, an evil demon with goals of world domination, also inhabits her body in order to counterbalance Chai Ka's existence. The two constantly battle for control, and they manifest from Wild Flower's body in order to fight.
