According to the search results, Tai Lung is the main antagonist of the Kung Fu Panda franchise. He was Shifus adopted son, a former student, and an accomplished Leopard Style kung fu expert. Tai Lung was defeated by Po when he used the Wuxi Finger Hold on him. The Finger Hold sends its opponent to the Spirit Realm, indicating that Tai Lung now resides there. After his defeat, he continues to be seen in flashback sequences. There are some fan theories that suggest Tai Lung may have survived his defeat, but there is no official confirmation of this. It has also been reported that Tai Lung will return in Kung Fu Panda 4, being summoned back to the realm of the living by a new enigmatic villain known as The Collector.
