Synopsis
Master Oogway (Randall Duk Kim) is residing in the Spirit Realm. There, he is attacked by Kai (J.K. Simmons), a large yak who was Oogway's ally, but turned against him 500 years ago. Oogway sent him to the Spirit Realm, where he collected the chi of every warrior there. He beats Oogway, and takes his chi, turning him into a jade amulet which Kai wears on a belt along with the rest of the warriors. With Oogway's chi, he is able to open a portal to Earth.At the Jade Palace, Po (Jack Black), Tigress (Angelina Jolie Pitt), Monkey (Jackie Chan), Mantis (Seth Rogen), Viper (Lucy Liu) and Crane (David Cross) order lunch at Mr. Ping's (James Hong) noodle shop, and then go back up the mountain. Po tries to get them to do a dramatic entrance into the palace, and demonstrates by moving to kick open the door, when Master Shifu (Dustin Hoffman) appears in front of him. Shifu does a real dramatic entrance, and then breaks the news that this will be his last day teaching, and that from now on, Po will be their teacher.Po tries to shout out commands to the team to guide them through an obstacle course, but his commands only make them crash into the obstacles and each other. Po goes to a statue of Oogway and apologizes, and Shifu pops up next to him. Po tells Shifu that he is done with teaching, and Shifu tells him that Oogway named him the Dragon Warrior because he could do more than just fight. Shifu harnesses chi energy to make a flower bloom. Po says he'll never be a good teacher like Shifu, and Shifu replies that he's not trying to turn Po into himself, rather, he's trying to turn Po into Po. Po is thoroughly confused.Kai goes through the portal and lands on a farm. He tosses his jade amulets on the ground, and they turn into warriors. He instructs them to bring him Oogway's students.Po is at home taking a bath, and he gets interrupted by Mr. Ling, his adopted father. Po tells him what happened earlier, and that he can't be a teacher. Mr. Ling tells him to take the job, and then Mr. Ling can sell noodles inside the palace. A pig pokes his head in and tells them that someone is about to beat Po's dumpling-eating record. They go downstairs, but can't see who is eating the dumplings. Once the record is broken, Po sees that it is another panda, bigger even than him. The panda introduces himself as Li Shan, (Bryan Cranston) and tells Po that he is looking for his son that he lost many years ago. Po tells him that he lost his father when he was a baby. They wish each other good luck and start to walk away. The other animals in the restaurant shake their heads.Po and Li stop and look at each other again. They notice each other's green eyes and huge bellies, and realize they're father and son. They hug each other, and Po introduces him to Mr. Ling. Po is unsure what to call them, since they're both his father. Li teaches Po the Belly Gong, where they bump bellies together, and both bellies shake. Po asks an artist to make a sketch of him and Li, but Mr. Ling puts himself in the picture. Li tells Po that there is a secret panda village where he had been living, and that he got a message from the universe that Po would be here. Po leads Li outside to show him around, and Mr. Ling sadly looks at his Po action figure.Po takes Li to the Jade Palace, and they both get winded climbing up the stairs. Po shows Li all the cool artifacts in the Hall of Heroes. Shifu and the others walk in, and Po introduces his father. Shifu asks if he will stick around to watch Po teach, but then a gong goes off, signaling that the village is under attack. They all go to the village, and find Kai's jade zombies. In battle, Po recognizes that they're fighting the great warriors of the past. The group gets the upper hand and pins down the "jombies," and they all start speaking with Kai's voice. They say that Po's chi will soon be Kai's, and then vaporize and fly away. Shifu tells them he doesn't know who Kai is.In the scroll room, Shifu finds a scroll that has information about Kai,
