History TearJerker / KungFuPanda3

->'''Li:''' She was the love of my life. And then... just when I thought I couldn't get any luckier... along you came, my little Lotus. I really had it all. Until that... one moment... when I... lost everything.

-->'''Li:''' I already lost you once, I don't want to lose you again. I can't.
-->'''Po:''' You just did.

* Master Oogway's brother-in-arms who he cared for like family...turned into a power hungry psychopath who would steal people's ''souls'' for power. Imagine how Oogway had to feel when he sealed Kai away...
** To Kai's credit, it's clear that at one time, he genuinely cared for Oogway just as much. The guy carried him for three days straight through a raging blizzard when he got injured in order to find a healer, and his expression there is both sad and fearful. When Oogway "betrays" him, you can see a very hurt look on his face for a split-second before he fights back. He truly doesn't understand why what he did was wrong, and thinks that his brother just turned on him for no reason. When he explains this to Shifu, he looks and sounds like he's on the verge of tears, a complete contrast to every other moment he's on screen. To make matters worse, it's revealed that Oogway threw the first punch in his original conflict with Kai, so from Kai's perspective Oogway simply turned on him one day for no reason..
** Even in present day within the spirit realm, Oogway's reaction to Kai revealing his scheme and what has become of the other masters is not anger and revulsion, but merely sadness, realizing his former ally is still going even further down the slippery slope. His reply sounds more like pleading to see the better side of his old friend again, it's hard not to imagine him having a similar exchange in their earlier fateful confrontation:
-->'''Oogway:''' ''*sadly*'' When will you realize, the more you take, the less you have?

* Despite all of Kai's villainous actions, it's hard not to feel bad for him when he realizes nobody remembers who he is. Even though he ended up becoming a bad guy, he still did a lot of good with Oogway before learning about Chi, even saying that he was once known all across China. Over the course of the entire movie he's always upset that people don't remember him, to the point that when Po actually knows Kai's old nicknames and titles, Kai is so happy he almost wants to spare Po's life. What's worse, it's heavily implied that the reason nobody remembers Kai is because ''Oogway'' did something to force people to forget, or simply allowed his name to fade into complete obscurity.

-->'''Kai''': Why not? He destroyed mine.

* After Po explains the plan to the pandas, he looks at the jade scroll from Kai's backstory. His father, Li, sees the drawing of pandas using the chi to cure Oogway, and tries to imitate it. He's still saddened for the fact that he lied to his son and that he never teached him to use chi because he never knew how to do it. His expression and Bryan Cranston’s performance are truly heartbreaking.
