[[caption-width-right:350: ''He remembered...'']]
* For an opener that runs pretty quickly over the main parts of the game series thus far, the fact that they decided to include Xion's mini-flashback to when she, Roxas, and Axel were eating sea-salt ice cream atop the clock tower - and the subsequent smirk on Xion's face that lasts about a half second before she disappears - says a lot about her significance to Roxas' story, especially since Roxas' part of the opener purely consists of Xion and Axel. It practically yanks at the heartstrings because despite her significance, anyone who's played 358/2 knows that NOBODY WILL REMEMBER HER AT ALL.
* The first cutscene involves Terranort watching as Even and Ienzo fade into darkness. Ienzo is a child, and his little body lying next to Even's...
** It's not at all hard to imagine [[ParentalSubstitute Even]] tried to save Ienzo from Xehanort and failed, getting his own heart stolen for his trouble, thus leaving Ienzo easy prey.
* The chronicle summarizing Days basically confirms Xion's suicide attack, stating: "The two fought and Xion got her wish: she was defeated."
* [[{{Film/TronLegacy}} The Grid]]. Don't let it's cool appearance fool you. It's the second saddest world in the game, behind only The World That Never Was. Of the characters found here, only two (Sam and Quorra, like the movie) survive to the end. And not only that, many, MANY, fans cried after defeating the boss in Side: Sora.
** Every worry comes true and then some. Tron[=/=]Rinzler serves as a boss for Sora, just to make things worse for the teen, and after Sora defeats him and uses the Keyblade to free Tron from Clu's control, Clu [[MoralEventHorizon tries to derezz them both with his disc]] [[IfICantHaveYou out of jealousy!]] While Tron was able to protect Sora from Clu, the disc creates a hole underneath him, causing him to fall into it. Sora tries to [[TakeMyHand reach out for his friend]], and Tron reaches back to him, but Sora ''can't save him'', resulting in the program ''falling to his death''. Sora even realizes that "Rinzler" was reaching back to him and what it meant, but they couldn't reach far enough. Worst of all, Clu was [[KarmaHoudini able to get away with this]]!
*** And then there's [[https://youtu.be/-b1p6TJpAC8?t=2540 Everglow's version of the battle]] for his "Kingdom Hearts Timeline" series. From the point Rinzler was about to lose the battle until his fall, Tron-centric clips from Kingdom Hearts 2 were edited in.
** Only [[HarsherInHindsight made worse]] by the fact that Tron was probably one of the past party members Sora was closest to (he even ''hugged'' Sora goodbye in his last appearance!).
** Just the idea that not only did the Grid fall to darkness and not wake up until Sora and Riku arrived, but it was already in ''Legacy's'' {{Dystopia}}n state by then, with its Tron reprogrammed by Clu, the [=ISOs=] aside from Quora derezzed, and Flynn having been in exile for 20 years. [[{{Understatement}} Life has not been kind to this place...]]
* In the [[WesternAnimation/MickeyDonaldGoofyTheThreeMusketeers Country of the Musketeers]], when Donald and co. realize they've been played for fools by Pete as he's managed to successfully kidnap Minnie, Donald via his pessimistic attitude bails on the whole thing. Mickey trying to call out to him running away with the music playing in the background just hurts.
* While it builds up [[Awesome/KingdomHearts3DDreamDropDistance a group shot of made pure awesome]], there's a moment during [[https://www.youtube.com/watch?v=NgncTPlWoJQ this cutscene]] that is one of the few tearjerkers able to punch players in the gut with ''one word'':
--> '''Sora:''' ''[[TheWoobie "Wait...!"]]''
** Worse still is a moment later, when Riku's voice just ''barely'' cuts through the nightmare. He's ''begging'' Sora to stop following the dreams, and [[HopeSpot it almost looks like it's going to work,]] but he ''just keeps running.''
* After Sora meets Roxas, he is made to know what happened in 358/2 Days, much like what happened near the end of coded. However, it's even sadder than the equivalent scene in coded. Sora is basically staggering under the weight of all that he just learned, and he comes out with this line:
-->'''Sora:''' Not again... Did ''they'' cause all this pain...? ''...WHAT DO YOU WANT ME TO SEE?!''
** Notably, he did cry when he met Xion, [[ImCryingButIDontKnowWhy although he didn't know why.]] Just seeing her raven-colored hair was enough for those who ''did'' [[DownerEnding know why]] to continue mourning.
* In relation to Sora's Dreams in The World That Never Was it ''HURTS'' to see Terra and Aqua turning away from Ventus.
* The revelation that Nobodies ''did'' manifest hearts without knowing it puts Axel's dying lines from ''KHII'' in a new depressing light.
-->'''Axel:''' I wanted to see Roxas. He...was the only one I liked. He made me feel...like I had a heart. It's kind of...funny...you make me feel...the same...
** Hell, it makes some lines from ''KHII'' more depressing in hindsight...
-->'''Demyx''': Oh, we too have hearts, don't be mad...
* Just the fact how genuinely ''upset'' Sora sounds when he asks how Xemnas could lie to the Organisation about not having hearts. It's made even worse when you remember how Sora constantly looked down on the Nobodies for not having real feelings in ''KHII''...
* After Sora defeats Xemnas, [[https://www.youtube.com/watch?v=shSewy-veQQ this scene]] shows he is absolutely winded. Peppiest guy in the world, never shows he's tired for a second, actually allowing that shell to crack. Even worse, his heart has finally snapped, and has given into the darkness, ending his side of the story in the [[{{TheHeroDies}} most tragic]] [[{{DownerEnding}} way possible]].
-->'''[[{{DyingAsYourself}} Sora]]:''' [[SayMyName Riku]]...
** It's almost as if he's using the last of his strength to call out for Riku to come save him... because Sora knows that it's too late for him to save himself.
** And Ansem [=SoD=]'s conversation with Riku shortly after implies that he could ''feel'' Sora's heart breaking and falling into darkness.
* Master Xehanort's ButForMeItWasTuesday speech on Terra, Aqua, and Ven. Talk about KickThemWhileTheyAreDown. Master Xehanort admits that he messed up in ''Birth by Sleep'' and acted rashly, and goes so far as to dismiss his actions as "little mistakes" in the Japanese dub. This ''enrages'' Mickey, who snaps back that his "little mistakes" ruined the lives of his friends.
** FridgeHorror - Tearjerker, the first line of said speech "But destiny is never left to chance", we seen it before, it was one of the lines appearing in the ''Birth By Sleep'' trailer, we had this very speech foreshadowed since before we got to know the trio in the first place. Whereas then it was a cool ominous tagline, Master Xehanort's speech here cruelly retcons it into seemingly being about how the trio were doomed to suffer horrible fates at his hands - and ''he doesn't care''.
* The look on Lea's face when Isa attacks him while he is rescuing Sora.
** And for that matter, the revelation of what ''really'' [[FateWorseThanDeath happened to Isa]] after he became a Nobody.
* From the ending bits of ''VideoGame/KingdomHearts3DDreamDropDistance'': It's gut-wrenching seeing Sora end up exactly like Ventus. Sure, Lea comes in as a {{Big Damn Hero|es}} and saves Sora from becoming a Xehanort clone, but again, Sora=Ventus right now. Comatose with a shattered heart teetering on oblivion. It was scary finding that we were so close to losing him... to losing EVERYTHING...
** Just looking at him [[{{PeacefulInDeath}} sleeping peacefully]], back in his true form, in Yen Sid's Tower, is heartbreaking.
** And finally, when a comatose Sora is brought back to Mysterious Tower, Mickey worries that history is repeating itself with what happened to Ven. It shows that Mickey has never really gotten over what happened back in ''Birth by Sleep'', and the he's worried to lose someone else the same way as Ven.
* The fluffy, happy feelings tears here - Eraqus wrote Terra off for having Darkness in him. Yen Sid ''did not'' write Riku off for having Darkness in him as it's part of him now. He appointed Riku a Keyblade Master because he was ''worthy'', regardless of Darkness or not.
