Jin Ying is the deceased mother of Gene Khan.
Jin Ying told her son, Gene Khan, about his destiny to have the Makluan Rings. Later, for unknown reasons, she married Xin Zhang, who she said would help him on his journey to become the ever powerfull Mandarin. She disappeared soon after (it is not said specifically how) and, to Gene's rage, Zhang claimed the Makluan ring Jin wore around her neck for himself. Currently it is thought that Jin Ying is dead and Gene is looking for the Makluan Rings to bring Jin Ying back to life
