Kung Fu Panda (2008)

In the first Kung Fu Panda film, Po (Jack Black) was dubbed as the Dragon Warrior by Master Oogway (Randall Duk Kim), much to the protest of Po and his fellow masters. During his subsequent training, Master Shifu (Dustin Hoffman) and the Furious Five made no secret of their disdain for Po, assigning him rough physical activities in hopes of discouraging him. However, with the encouragement of Master Oogway, Po endures the abuse without complaint, hoping that they could eventually change him into someone respectable. This display of indomitable tenacity, although frustrating to Shifu, soon impresses most of the Furious Five, who begin to warm up to Po, whom they also end up finding to be an excellent cook.

Shifu, discovering that Po can perform considerable physical feats when motivated by food, uses this to train Po with a custom training regimen. At the end of the training, during a chopstick-sparring match over dumplings, Po demonstrates considerable skill in combat—which includes Po's use of his bulk to his advantage—and some emotional maturity allow Po to somewhat reduce his emotional dependence on food. This is evident when Po eagerly gives the last dumpling back to Shifu after winning the sparring match, stating that he is not hungry.

Now convinced of Po's worthiness, Shifu presents the legendary Dragon Scroll to Po, only to find that it's just a blank reflective surface. Shifu and the team soon learn that the snow leopard Tai Lung (Ian McShane) has escaped from Chorh-Gom Prison, where he was held under maximum-security-like measures. In despair, Shifu orders Po and the Furious Five to help the villagers escape while Shifu buys some time by engaging Tai Lung in a fight to the death. As Po helps his father, Mr. Ping (James Hong), to escape, Ping reveals that the secret ingredient of his "Secret Ingredient Soup" is nothing; instead, people only had to believe it was special. With this advice, Po realizes that the scroll's true empowering symbolic value: whatever someone turns themselves into, with enough dedication, can make them the best version of themselves.

Encouraged, Po is then able to challenge Tai Lung in a climactic battle and defeat him with an improvised combat style, using his body fat not only to shield his nerves from qi strikes but also for deflecting attacks. Amazed by his new talent, the Furious Five finally acknowledge Po as a true kung fu master with respect, much to his surprise. Since the film's climax events, Po has now divided his time between practice, working at his father's noodle shop, and teaching children martial arts.

Kung Fu Panda 2 (2011)

In Kung Fu Panda 2, the villainous peacock Lord Shen's (Gary Oldman) wolf forces perform a raid looking for refined metal to use in Shen's cannons. The attempt of Po (Jack Black) and the Furious Five to stop the raid is thwarted by seeing the fealty symbol on the Boss Wolf (Danny McBride). The symbol gives Po a traumatic childhood flashback of the attack on his village and freezes him on the spot. He discovers that Mr. Ping (James Hong), a Chinese goose, is not his birth father; rather, he was only adopted by him. When Po asks about his past, Ping has no knowledge of anything from before he found Po behind the noodle shop.

When Po is sent with the Five on a mission to stop Lord Shen's attempt to conquer China, he is plagued with disturbing dreams about his parents replacing him with a radish. He is reluctant to talk about them, even to Tigress (Angelina Jolie), who grew to be Po's confidant among the Five. More seriously, Po is still hampered with his paralyzing flashbacks, especially at the sight of the same symbol on Lord Shen's plumage. This creates a subsequent obsession in Po to question Shen, which results in him almost getting killed.

Po survives Shen's cannon attacks and is rescued by the elderly Soothsayer (Michelle Yeoh), who heals Po's body with acupuncture and medicinal brew. Po, now able to recall all his memories of being orphaned, finds inner peace in light of recalling the happy and fulfilling life with his loved ones in the 'Valley of Peace.' By achieving tranquility, Po defeats Lord Shen's fleet—much to everyone's astonishment—by using a martial arts technique that counters Shen's cannon fire by literally grabbing the fired projectiles and returning them destroy their launchers. In doing so, Po saves China while cementing his reputation as one of the mightiest warriors. Afterward, Po returns to his adoptive father, Mr. Ping, and tells him that he is, in fact, his dad for having adopted him. However, Po is unaware that his biological father, Li (Fred Tatasciore), is still alive, living in a panda hideout with the other villagers revealed to be the secret panda village. He finally senses that his son is alive.

Kung Fu Panda 3 (2016)

In Kung Fu Panda 3, Po (Jack Black) is promoted to be a teacher when Shifu (Dustin Hoffman) decides to retire from active duty to focus on honing qi. However, in his first lesson, Po's attempts to train the Furious Five ends disastrously, with the Five injured as a result. Po, demoralized and full of doubt, goes to Shifu for advice, who reveals that he'd deliberately set Po up to fail to help teach him a lesson and advises him that he must be himself. When Po also tries talking about his problems with his father, Mr. Ping, they are interrupted by the arrival of Li Shan (Bryan Cranston), Po's biological father, who breaks Po's dumpling-eating record at the restaurant. After recognizing each other, Po and Li Shan bond, much to Mr. Ping's jealousy. Shortly after bringing his father to the Jade Palace and introducing him to his friends, the Valley of Peace is attacked by living jade statues (referred to as "Jombies" by Po and Monkey) resembling kung fu masters both past and present. After the statues retreat, Po and the others learn that they were sent by Kai (J.K. Simmons), a ferocious warrior who was once Master Oogway's ally. From Oogway's journal's they realize that Kai and Oogway learned the secrets of chi from the pandas from Li Shan's village some 500 years prior. Oogway then banished Kai to the Spirit Realm after Kai tried to take the pandas' powers of chi for himself. As Kai can only be defeated by a master of chi, Po decides to learn the power of chi on Li's suggestions as it was an innate ability of the inhabitants of the panda village. Po is told, however, that he must learn to live like a panda, which he takes to upon arriving in the village and is glad to be a part of.

Later on, Tigress arrives at the Panda Village, revealing that Kai has taken the chi of all the kung fu masters, including Shifu, Crane, Mantis, Viper, and Monkey (she is the only one to escape) and that Kai has destroyed the Jade Palace. Terrified, Li begins evacuating the village while Po demands to be taught how to utilize chi. Li then admits he lied about knowing how to use chi to bring his son home and that all the pandas have forgotten how to use the ability. Hurt by his father's deception, Po isolates himself and trains rigorously to fight Kai, with his self-doubt returning. After talking with Tigress and discovering that Li and the other Pandas have decided to stay and help, Po trains the village to use kung fu. When Kai attacks the village with his jade army, Po's unorthodox forces and tactics initially gain the upper hand. However, when Po tries to use the Wuxi Finger Hold on Kai, he is told by Kai that the technique only works on mortals. Kai then overpowers Po and prepares to take his chi. In a last-ditch effort to save his companions, Po grabs Kai and sends them both to the Spirit Realm, where they battle again and Kai prepares to take Po's chi. After learning from Po about who they are, Li, Tigress, Mr. Ping, and the other pandas use their chi to save Po, causing him to generate a dragon-shaped avatar composed of chi and defeat Kai by overloading him with the flow of chi from within him.

In the aftermath of the battle, Oogway appears to Po and reveals that Po's journey has come full circle; Oogway reveals that he specifically chose Po as the Dragon Warrior because he is a descendant of the ancient pandas who helped him centuries ago and that Po is the physical embodiment of the Yin and Yang, the right successor to the legacy that Oogway has built. Oogway also reveals that he was responsible for alerting Li Shan to Po's survival and is proud to see how Po has grown and matured. Oogway then presents him with a mystical jade staff that he had earlier when he enter the Spirit Realm to help him return to the mortal world and calls him a master of chi. Upon returning to the Mortal Realm, Po reunites with his family and friends and returns to the Jade Palace, gazing proudly at his legacy and the place where his journey first began. He then instructs the pandas, the kung fu masters and the Valley of Peace residents in giving chi, which spreads good chi across the land.

Afterward, Po began to consider other possible career paths, such as a cleaner, comedian, dancer or doctor and made a list of them on a scroll. This scroll later inadvertently ended up in Tigress's hands (Kari Wahlgren), who mistook it for a list made by Shifu of four warriors she was to gather to face the villainous Boar. This led to her recruiting Crane (David Cross), Monkey (James Sie), Viper (Lucy Liu) and Mantis (Seth Rogen), who was quickly dismissed by Shifu, who also ordered the evacuation of the valley.

During this time, Po revealed to his father that he had caused Shifu's illness, which his father took as good publicity, and was then sent to gather ingredients for meals to be served to the fleeing villagers. From the hilltop his father had specified, Po then watched as the future Furious Five battled Boar and quickly determined what he wanted to do with his life: practice kung fu. He later made a set of Furious Five action figures, which he treasured for years.

In "Bad Po," it is revealed that Po has a split personality: one is kind, considerate, caring, polite, sensitive, very positive, helpful, hard-working, selfless and compassionate (which makes him "Good Po") and the other one is rude, very negative, lazy, sadistic, unhelpful, heartless, abusive, mean-spirited, selfish, manipulative, mischievous, cruel, uncaring, destructive, misbehaved and devious (which makes him "Bad Po" or "Evil Po"). Both of his personalities have been split when he gets infected by the Mystical Mirror of Yin and Yang.
