History Heartwarming / Undertale

*** Like Undyne, Mettaton trying to kill the character might leave a bad taste in anyone's mouth, but the reason why he is determined to do so is opposite to Undyne's but still has a valid point: he doesn't want to endanger his own people for an impending war that they will surely lose.

* The Winter 2024 Undertale/Deltarune newsletter that was released on Valentine's Day has several [=GIFs=] related to the day, one of which is of Papyrus opening his mailbox, only to find that it's still empty. Towards the end of the newsletter, the ''[[SitcomArchNemesis Annoying Dog]]'' of all characters [[PetTheDog gives Papyrus a letter]], which cheers him up.

* The Spring 2023 Undertale newsletter mentions that Grillby can't make a snowman due to being made of fire. Two children made a snowman of him, and he keeps a photo of it at Grillby's and considers it his prized photograph.

* Coming from ''[[{{Jerkass}} Flo]][[AxCrazy wey]]'' of all people, but in the [[https://undertaleqa.tumblr.com/post/150442381178/papyrus-whats-your-favorite-food Undertale Q&A tumblr]], Flowey seems to actually ''bother'' remembering what Papyrus' favorite food is. Given [[OmnicidalManiac how]] [[TheSocialDarwinist he's]] [[TheSociopath usually]] [[StrawNihilist like]], it's a bit endearing to know that he takes the time to remember what Papyrus likes.

* While befriending Undyne is primarily hilarious, her comments about not wanting to put Papyrus into harm's way because he's too nice for battle are surprisingly endearing. And, as you find during a No Mercy run, completely correct.

[[folder:Meta]]
* Toby's tweets about ''Undertale'' frequently have comments like "People tell me that ''Undertale'' helped them through a hard time, or made them want to be a better person." It's an amazing show of just how this game has touched people who have played it.
* It's very clear that one of Toby's primary goals with ''Undertale'' was to give commentary on and open up questions about human morality, with it being such a massive DeconstructorFleet on tropes like VideoGameCrueltyPotential and the way SaveScumming can be used like an OmniscientMoralityLicense. Now, bear that in mind, and look at the way the video game community has treated Undertale: go to practically any message board, comment section, blog post, etc., and you will find many, many, ''many'' people saying things like "After only an hour of playtime, I knew I could never do the Genocide route", "I felt bad for telling Sans his brother isn't cool - how could anyone even ''think'' of doing the Genocide run?", and "I can't even bring myself to kill one Froggit." You'll also find people who started a Genocide run but [[HeelFaceTurn soon found themselves regretting their choices so deeply]] they Reset to [[SetRightWhatOnceWentWrong fix their mistakes]], with the citing breaking point often being [[IfYoureSoEvilEatThisKitten having to fight an especially lovable character]] like [[MamaBear Toriel]] or [[AllLovingHero Papyrus]], as well as people who talk about completing the Genocide run with [[MyGodWhatHaveIDone sincere, genuine regret]], like it's [[MyGreatestFailure the biggest mistake they ever made as a gamer]]. Sure, there's plenty of people out there who claim to have played the Genocide run without batting an eye, but for every person doing so, there's at least a dozen others saying the opposite. Considering this is the gaming community we're talking about, with all the ugly stereotypes and negative reputations it's spawned over the years, a response like this goes beyond just being refreshing - if you take Undertale seriously, as more than "[[MST3KMantra just a video game]]", as the moral commentary it was meant to be, then being part of the fan community can do [[RousseauWasRight incredibly healthy things to your faith in humanity]].
** In particular, statistics show that a majority people very likely stopped a Genocide Route at a very specific point. What was it? '''''Papyrus.''''' That's right, his nonstop kindness and understanding ''even if you kill him'' got a large percentage of people playing Genocide to pull a MyGodWhatHaveIDone and stop then and there. People say that even if they were slightly bothered about killing monsters before, at least they ''attacked you first'', so you could slightly justify it as self-defence. They just couldn't go through with killing a guy that just wanted to be your friend, or they felt massive guilt after doing so.
* The game has a massive fandom, and with a large fandom comes lots of Fanfics. What is, by far the most numerous (with several of them being by far the most popular) fanfics? Ones where Asriel is saved. People really want to give him the happy ending he can't get in the game.
* Scrolling to the Kickstarter page for ''Undertale'' reveals his amazement at the fact the game's concept proved so popular that it reached its funding goal ''instantly''. Toby is clearly very grateful to his fans and it's quite touching.
* [[http://undertale.tumblr.com/post/130409309755/greetings Toby Fox has a small message on the official tumblr blog about gaming responsibly]]
* The official Undertale artbook has commentaries from Toby Fox and the artists that worked on the character designs and some of the commentaries are quite heartwarming. Toby originally was going to have Toriel be killed by the player, but as he wrote her dialogue, he felt completely shamed about killing her off and wanted to make it possible to get past her without having to kill her. From there, he made the game be possible to complete without having to kill a single person.
* [[https://undertale.com/alarmclock/ The "Winter" dialogue]] from the currently delayed Undertale alarm clock app reveals more lore during the cast's time on the holidays.
** Papyrus held a Christmas party with his own... unique flair. While it got rowdy near the end, many of the characters came to appreciate the time they spent there.
*** Papyrus observed his brother sleeping on the couch by the end of the night, and tucked him in, despite Sans usually being the one to take care of his brother. Papyrus believes that, even if he never said it aloud, Sans must have been [[TheAntiNihilist very happy to be able to celebrate the holidays with so many friends]], and he can't even remember the [[StoicWoobie last time he could see his brother so happy]].
*** Sans, in turn, is proud of his brother for putting so much effort into celebrating with his friends.
*** Alphys enjoyed her time at the party with Undyne, singing karaoke and admiring how she looked with the Mew-Mew Earmuffs that she gave her.
*** Mettaton confronted Mad Mew Mew over concern over Napstablook, which unfortunately [[AlcoholInducedIdiocy escalated into a fight]] when they took too much "[[FrothyMugsOfWater ghost juice]]". When things settled down, Mettaton and Mew Mew looked on towards Undyne and Alphys, glad that they had each other and were happy together.
** Flowey remembers staying in the Ruins, watching Toriel live alone. His sadistic nature had led to him looking down on her for how she had fallen, but while falling asleep on the floor, she touched Flowey's face and said:
--->'''Toriel''': Asriel... I'll never let you go again...
*** Toriel recalls knowing ''someone'' that would fill their glass all the way to the brim, being "the most efficient way to fill it"; which Asriel would then mimic, and naturally spill about. When she woke up from the floor of the Ruins, she found a glass just like that. Passed out after she got too rowdy at the Christmas carol karaoke, she once again woke up to a glass filled to the brim with water. [[spoiler:[[AwLookTheyReallyDoLoveEachOther It's heavily hinted to be from either Flowey or Asgore]].]]
*** The very fact that Flowey's on the surface and still seems to care about his mother despite supposedly being "unable to feel love" shows that deep down, Asriel might still be in there somewhere.
*** Furthermore, when asked what kind of gift he would like for Christmas, Flowey states that he's too grown-up to want presents. He then goes on to give the specific example of "a red bike with a golden basket" as a gift that would be useless to him, with a coy smile.
*** Flowey then acknowledges that the reader's likely wondering about the ribbon he's wearing during the alarm clock dialogue, he deflects the question by saying "Who cares who gave it to me?" but vaguely hints it was Frisk who gave him the ribbon. Considering how none of the other characters reference Frisk in any matter, this heavily suggests Frisk is perfectly content sitting on the sidelines peacefully observing the hijinks of their new friends and family, who likely were not bringing them up in dialogue just to protect Frisk's privacy.
*** It's later revealed it's actually Papyrus who gave it to him, saying that he gave a matching red scarf to his friend who went missing later. That said, the fact that it's implied that the dialogue options are all directed at Frisk is heartwarming enough.
** After Undyne's hockey game, Toriel served everyone a thermos of alphabet soup.
** Asgore further recounts his old friend Rudy, following him from his youth to college and his twilight years, before he eventually [[NeverSayDie "fell down"]]. His favorite memories would include how they re-enacted Santa Claus and his reindeer, giving gifts to others in Snowdin. He laments that he was unable to show him the sun when the barrier was finally broken, but is glad to see that his daughters will not only get to see it, but grow up safe and happy in their now-hopeful world.
*** Hell, the very fact that the existence of the alarm clock shows that the Pacifist route is indeed the 'canon' ending, if there is one, as everyone's living happily on the surface with no worries about resets and timeline hijinks whatsoever.
** Everyone gathers at a massive super-tree they've set up, passing around warm soup and preparing to sing carols. They're all just so glad to be celebrating a wonderful winter... [[spoiler:[[Funny/{{Undertale}} even if the Christmas spirit is a bit unfitting for]] [[ChristmasInJuly September]].]]
* As a form of {{Woolseyism}}, the official Japanese translation of the game makes the brotherly bonds between Sans and Papyrus all the more touching. Not only are Papyrus' reactions to Sans' goofy antics toned down to be less vitriolic, but rather than referring to Sans by a first name basis, Papyrus instead opts refer to him as "Nii-chan" (big bro). And Sans is just as supportive of an older brother as he is in the original translation.
* Overlaps with SugarWiki/AwesomeMusic, but the song ''Hopes and Dreams'', which was inspired by {{Music/Anamanaguchi}}, would eventually be [[https://youtu.be/wAVjuzUeWD8 covered by the same band that inspired it]] in 2021, bringing it full circle.

** And if you are doing a No Mercy Run, Papyrus won't even fight you but instead say that he believes you have the potential to become a better person... ''even after you kill him!'' This skeleton is basically MERCY incarnate. And it works. On a meta level, he's the main reason many people turn back on their No Mercy runs.
** Another meta example. What's Papyrus' greatest desire? To join the Royal Guard... namely, so everyone will respect, admire, and love him. For all his boasting, it quickly becomes clear that Papyrus desperately wants friendship and love above all else. And in the fandom... Papyrus is ''universally'' beloved. You'll be hard-pressed to find a fan that dislikes him, and most players rank him as one of their favorite characters, if not their absolute favorite. People love him for his showboating, his {{Adorkable}} personality, and his unrelenting kindness. So, in a way, Papyrus got what he always wanted, just by being himself.

** You'll know you're on the True Pacifist route when Toriel shows up to intervene when the fight with Asgore is about to start. She says that every creature deserves mercy -- [[WomanScorned even if she personally is not ready to befriend the person you were just facing.]]
*** During the credits, it shows Asgore trimming a bush of Papyrus in front of Toriel's school, which could mean that the two are slowly trying to become "friends" again.
*** A subtle one is added onto this. During the battle with Papyrus, he says a multitude of things that one can write off. Undyne liking him, him becoming captain of the Royal Guard, the king trimming a hedge in the shape of his smile, and having friends. In the end, Papyrus gets everything he ever wanted. Well, except for becoming captain of the guard.
---->'''Papyrus''': [[SugarWiki/FunnyMoments TRULY, THIS IS THE WORST]] [[LeaningOnTheFourthWall POSSIBLE ENDING.]]
** In the True Pacifist Ending, after spending the entire game unable to call Toriel because a dog stole her cell phone, Toriel will learn how to text message you. Most of the messages go from silly to ridiculously sweet and heartwarming.
** Your last choice on the True Pacifist route is a prompt from Toriel. If you choose to stay with her, there's one last post-credits scene where she sneaks into your room while you're asleep to leave you a slice of pie, looking at you adoringly before closing the door again.

* Frisk is (if chosen) HappilyAdopted by Toriel in the True Pacifist ending. The final scene is Toriel bringing a slice of pie while the child sleeps in their new room. Toriel stares back adoringly at them before closing the door quietly.

** The fact that Toby was able to layer on just how utterly dedicated Sans is to his brother [[http://thestarjar.tumblr.com/post/129810528270/sans as thickly as he did]] while still retaining enough subtlety and balance to keep it from being unrealistic or [[TastesLikeDiabetes annoyingly schmaltzy]] deserves a mention in and of itself.

* During the fight with Sans, he offers you a chance to stop the fighting. Accept his offer, and he...[[MoodWhiplash proceeds to kill you with an unavoidable attack]]. While this appears cruel at first glance, and rightfully so considering you [[KillEmAll killed just about everyone in the Underground]], there's more to it than that. A common interpretation is that he's appealing not to the player ''specifically'', but to Frisk, the character you control. [[IKnowYoureInThereSomewhereFight All he wants is to get through to his buddy and convince them to start all of this over again.]] And when he says "get dunked on" after killing you afterward? That's Sans going back to his usual jokey self, content that he got through to Frisk.

* Cheering up [[TheEeyore Napstablook]]. It takes some effort, but they finally become happier. They even show you a trick where they make a NiceHat out of [[SwissArmyTears their own tears]]!

Undertale is very well known for touching people's hearts, and these moments definitely prove so.

* Really, seeing all the main characters interact and chat is very sweet. Even if they didn’t know each other before, they still befriend each other extremely quickly. Special mention goes to Alphys. After being so anxious, shy, and fearing everyone would hate her, everyone gets along with her well. She also stutters a lot less, and is more jokey and a lot more relaxed. Nobody has to be alone again...

* Overlaps with SugarWiki/AwesomeMusic, but the song ''Hopes and Dreams'', which was inspired by {{Music/Anamanaguchi}}, would eventually be covered by the same band that inspired it in 2021, bringing it full circle.

* It makes sense that Snowdin is the first location in the game. While every location is meant to evoke the Underground's lovely-yet-melancholy feel, Waterfall gives a beautiful tone and Hotland/The Core gives a badass tone. Snowdin, however, sets the game's "warm and fuzzy", adorable tone so well that (between the Christmas motif, the sweet background music, and it being the place that you see just how sweet everyone in the Underground is) it's SugarWiki/SweetDreamsFuel.

* Forgiving and embracing Asriel when he feels he doesn't deserve a damn thing and is absolutely awful and worthless, even though he was only how he was because of Frisk's DETERMINATION. It's made better by the fact that it's a [[VideoGameCaringPotential legitimate choice of the player to do this--you're still given the options to not forgive or comfort him]][[note]]Although admittedly very many people do comfort him[[/note]], which makes the emotional impact of doing so much stronger than it would be if the player was forced to via a cutscene or ButThouMust.
