* [[spoiler:Po, after landing in his hometown, now in ruins from Lord Shen's invasion, finally completely remembers why he lost his parents. Filmed from Po's perspective, his mom, pursued by his soldiers, intentionally leaves him in a pile of radish cartons so he would at least be spared and undetected, and before she lured away Shen's forces and he never saw her again. This is especially moving considering how, previously, Shen tries time and again to convince Po that his parents did not love him, just like he believes his own parents did not as well. The sweeping music, combined with the switch from 2D to 3D animation, and his mom's pained expression from giving up her baby, pulls at the heartstrings even more and making it hands down the saddest moment in a Dreamworks Animation film.]]
** To make it more tear-jerking, this realization pulls Po out of his two-Act-long HeroicBSOD, and leads to him [[HesBack to return to save his friends and make Shen pay!]]
** Ditto combined with FridgeHorror as you realise Po's line from the first movie about him eating while he's sad. His mom left him in a Radish crate that was full, and when he got to Mr. Ping's restaurant it was empty. On the bright side, it also makes his other line in the first movie, "I'm not hungry" all the more epic.
** It's the little things that make that scene, [[spoiler:like how gold is the color of heroism in these movies and Po's mom is literally glowing gold as she leads the wolves away. Or the fact that she is last seen with Shen himself chasing her down.]]
** Even more sad is that it is implied that [[spoiler: Po's Mother was killed.]]
* [[spoiler: Master Thundering Rhino being blasted to bits by Lord Shen's cannon.]]
** Not to mention the followup: [[spoiler:While Po and gang are being led to Lord Shen's palace, they come across a big groove in the ground and Master Rhino's hammer stuck upright at the end (with a large dent in it from the cannonball, no less). Whereby Wolf Boss pats it and chuckles evilly...]]
** It's actually worse if you watch Master Rhino in the holiday and masters special's because you get to see how noble and benevolent he [[spoiler:was before he died]]. The masters special even shows us that for a long time he felt as though he could never quit live up to his father's Kung-Fu legacy.
* [[spoiler: Tigress' BigNo and [[FutileHandReach Futile Paw Reach]] as Po is shot. Later, Po finding a badly injured Tigress after she took the bullet for him.]]
* [[spoiler: Po's reunion with Mr. Ping.]] Also a CrowningMomentOfHeartwarming.
* [[TheAtoner The Soothsayer]] sincerely telling Lord Shen that she hopes he finds happiness someday. [[spoiler: It becomes sad if you know [[AllThereInTheManual that she's the one who pretty much raised him]], and she probably knew full well that that would be the last time she'd ever see him.]]
** [[spoiler:It becomes worse when he ''does'' find happiness and peace of mind eventually... [[FaceDeathWithDignity two seconds before]] [[DeathSeeker he dies]].]]
** Watch Soothsayer's face when he first reappears: she's surprised and is actually a little bit happy - before he starts making threats.
* Boss Wolf's expressions as he struggles with the need to obey his master and the need to [[AFatherToHisMen protect his pack]]. [[UpToEleven It's worse]] when you take into consideration that he had been childhood friends with Lord Shen, and then he is [[spoiler:thoughtlessly, instantly murdered by Shen when he decides to stand up to who had once been his friend in a hopeless effort to save his kin]].
* The sight of all ten kung fu masters, the most powerful and noble warriors in the land, in the aftermath of the battle completely drained and utterly defeated, seemingly without a chance in the world... the shot of Shifu watching Po- either a surrogate son or a dear friend to him- [[spoiler:looking as if he was preparing for a ''SuicideByCop'']] makes this troper's heart break.
* [[spoiler:"My son is alive."]]
** Makes it even sadder is that for a long time [[spoiler: Po's biological dad had believed his family was killed that night.]]
* Tigress when the Furious Five are [[spoiler: all in chains after seeing Po take a shot point blank from the largest cannon in Shen's arsenal.]] It's not hard to see that [[spoiler: the apparent death of her closest friend]] has completely broken her. The only thing she can muster when Shen comes to taunt them about their defeat is a low growl and a look of pure, undiluted ''hatred''.
* Shen's normally stoic demeanor when talking about his parents breaking, if only for a moment, when the Soothsayer told him that they loved him so much that sending him away killed them. For the briefest of instants, you see a look of regret and maybe a little sorrow on Shen's face before he tries to cover it up.
* Ping's freak out as he's worrying about Po will make anyone tear up. FridgeBrilliance takes it one step further, as you realize than even though Po's a giant, fully-grown panda, Mr Ping still thinks of him as a baby, like ''any parent'' would.
--> '''Mr Ping:''' Why'd he have to go and save China? I mean, I know '''why'''...but '''why'''? *voice breaking* He's just...one...little...panda...
** Mr. Ping breaking down at the end, when he thinks Po isn't coming back, and then Po reappears.
* It's a quick moment, but after Shen breaks through the barrier and sails into the harbor, Po swims over to check on Tigress, and realizing he's the last one left to stop Shen, pushes her away; she reached after him, as if to try and get him to stay.
* No one's mentioned the part where we see Shifu after Po gets shot? When it happens, it cuts to Shifu who is dozens of miles away as he falls from his staff and looks very distraught, implying he can sense how his students are doing and thus knew what had just happened. The fact that Shifu had spent so much of the first film disliking Po and trying to get rid of him, to this film where he looks completely heartbroken thinking he's been killed is both heartwarming- and wrenching at the same time.
