Kai eventually arrived at the Jade Palace where he attacked the rest of the Five and Shifu, destroying the palace in the process. Kai destroying Oogway's statue in the Master Garden
Although the masters confronted and tried to fight Kai, they were, one by one, all easily defeated and had their chi stolen, along with all other masters in China, from the sea inward. He then summoned his warriors back to his side, and Crane and Mantis were ordered to investigate his current location, joining up with Masters Bear, Croc and Chicken, whose villages had also been attacked. They eventually found Po and the Furious Five, whom Kai witnessed through the "eyes" of his soldiers as they fought them. Upon his return, Kai ordered several of his jade soldiers to find Oogway's students. Kai swore to take the Dragon Warrior's chi and subsequently used Oogway's chi to return to the mortal world. Although nearly equally matched, Oogway was ensnared and his chi was stolen, but not before warning Kai that he had set another on the path to defeat him. In this time, Kai challenged Oogway to a rematch, in which he explained that he had taken the chi of every master within the Spirit Realm, much to Oogway's chagrin. In Kung Fu Panda 3 Rise to powerįive hundred years after his banishment to the Spirit Realm, Kai, having become vengeful and power-hungry over time, underwent a physical transformation : his mane grew longer and more unruly, and Kai's general regalia, consisting of an armored uniform, was gone. Seeing the damage Kai's obsession would cause, Oogway broke off his relationship with Kai, and the two former friends fought fiercely until Oogway finally triumphed, banishing Kai's body and soul to the Spirit Realm. Kai, however, became interested solely in using it to take over the world by increasing his own power, so he began taking chi from others rather than giving it. Fascinated by the power, Oogway was taught by the pandas on how to utilize it. They then happened upon a secret village of pandas, who used their knowledge of chi to heal Oogway. One day, during an ambush, Oogway was badly wounded and Kai carried him for days, searching for help. They were good friends and together they fought side by side, leading a great army into battle. Approximately five hundred years prior to the events of Kung Fu Panda 3, Kai was a warrior alongside Oogway, with whom he grew a brotherly bond with.
