General Kai (also known as The Collector) is the main antagonist of Kung Fu Panda 3. He was a warrior and the general of an army, which he led alongside his brother-in-arms, Oogway. Kai fought alongside Oogway as best friends, but after he learned how to steal the chi of others, Oogway banished him to the Spirit Realm. Across five hundred years, Kai stole the chi off of every kung fu master that entered the Spirit Realm, turning them into Jombies. Once stealing Oogway's chi, Kai returned to the mortal realm as a Spirit Warrior and sought to steal the chi from all living kung fu masters and destroy Oogway's legacy. With the help of his jombies, he nearly accomplished his goal, but he was eventually defeated by Po.
