Wu Xiong was the only one that survived the events of Lei Ting's grandfather's plots. She escaped back into the jungle with the gorillas after Duan Chang Ren sacrificed himself to seal away the dimension-travelling door. Ten years after, she became the only clue to the events that happened ten years before. While Geng Lie was doing a mission, he used his Yi Neng to fight. Sensing Yi Neng, Wu Xiong saved Geng Lie and mistook him for Ya Se until he returned her her lost memories with his Yi Neng. Wu Xiong remembered herself as an 18-year-old and led the new generation of the Ultimate Class to find out what happened to all the power users in the Gold Dimension.

Physical AppearanceEdit

In the initial episodes that she appeared in, she had long hair that covers her face and wore clothes that made her look like a gorilla. But later on, she changed her image when Ya Se reminded her that she is living in a human society. Her human outfit gave impression to everybody around her, including Ya Se, who did not like her at first.


Because of her gorilla-like appearance and behavior, everyone in class refer to her as "Jin Gang Mei Mei" (金剛妹妹 / Little King Kong Sister).

Bear Pearl

Wu Xiong is the bearer of the "Bear Pearl" (熊珠), a special orb given by the gorillas when she was young. With it inside her body, she is given invulnerability and rapid regeneration; an ability that accelerates the healing process if the damage is too much for her invulnerability to take. It also has the power to disperse or block any form of demonic energy.

When she gave it to Ya Se, she began to fall ill and eventually collapses. The doctor discovered that she had begun to age rapidly because of the lack of the Bear Pearl and needed it back within one month, by which she would die of old age. Ya Se returned it in episode 21. However, shortly after it was returned, she used it once again to end the battle between the Martial Arts Syndicate and the KO fighters. she is later seen in K.O one 2 where she has forgoten everything.
