Master Mao is Jungle Fury Rangers' previous mentor and bearer of the Cat Animal Spirit.
Judging by his form after his death, he seems to control the Caracal spirit. In Now the Final Fury Master Mao along with Master Rilla, Master Guin, and Master Lope come through the Spirit World portal to join the Rangers in the Beast War. Calling on the full power of their animal spirits, the Masters are able to send the Beast Army back into the Spirit World. However, this victory is also moot when Dai Shi drains the Masters of their Spirits' powers. Master Mao eventually regained his powers following Dai Shi's destruction by Casey, Theo and Lily. Later, after seeing the Pai Zhuq Academy in good hands, Master Mao returned to the Spirit World.
