History TearJerker / Undertale

* First, when you arrive at the Dog Shrine: if you played the UsefulNotes/PlayStation4 version and made the room full of life, seeing all its stuff used and broken can be depressing.

** Killing Toriel in the "neutral" path has her GoOutWithASmile, telling you one more time to be good and how strong you've become. This is especially easy to [[PlayerPunch do on accident]], because unlike many previous enemies, you can't spare her when her HP is low enough; attacking when her HP decreases enough will [[PlayerPunch suddenly do way more damage than usual and kill her]]. And if you feel guilty killing Toriel afterwards and you decide you want to restart and spare her, Flowey will call you out by saying this:

** An oft-overlooked but crucial detail that makes it hit even harder: Papyrus' fight is specifically designed so that you can't kill him on accident. Even with the best equipment and the highest LOVE you can get on a Neutral Run up until that point, it's impossible to reduce his HP to 0 before he offers to spare you. [[VideoGameCrueltyPotential If you killed him, you]] ''[[VideoGameCrueltyPotential have]]'' [[VideoGameCrueltyPotential to have done it deliberately]].

---> "02... I never told him..."\\
"01 holds his head in his hands."

'''Asgore''': I cannot take this any longer.\\
'''Asgore''': I just want to see my wife.\\
'''Asgore''': I just want to see my child.

* If you fail a Genocide Run at the Core, forcing it back into a Neutral Run with almost everyone dead, Alphys takes the throne. The first thing she says to you over the phone? ''"I just called to tell you. '''[[WhamLine I hate you]].'''"''. Not only is it so jarring to see from a normally very friendly ShrinkingViolet like her, it gets even worse when she mourns all of her deceased friends and fellow monsters whom you killed: hoping that [[SuicideByCop eventually, you would get her as well]] before Undyne's dying words (stated by her to be told in "[[OOCIsSeriousBusiness crazed desperation]]") made her realise that she had to evacuate the survivors to [[PlayingWithSyringes the True Lab]] and protect them, even if it meant them learning [[LiarRevealed the truth about her.]] She closes by musing ironically on the whole situation, that [[ForWantOfANail she could have saved everyone]] simply by [[CombatPragmatist killing you when she had the chance.]]

---> "02... I never told him..."

* Rounding out the Amalgamates is Endogeny. If you're at all a dog person, this one's going to ''hurt.'' The only way to end the encounter is to try to comfort and play with the bounding, blob-like dog monster. The fact that ending the encounter plays a slower version of the cheerful Dogsong, proving that there's still a dollop of delightful doggo in Endogeny, makes it hurt even more. What's more, the somewhat off-kilter tempo of Dogsong, which ordinarily lends it a goofy, jovial tone, makes it actually sound a little sad when slowed down — it ends up emphasizing that this big, weird, blobby dog is most likely in constant pain, but smiling through it all.

* She finally found a body she's happy not to possess, but to truly become, and this doesn't work: her raging outbursts, which were more ComedicSociopathy at this point, are actually the only thing she knew when she tried to become corporeal.

* The fight against Mad Mew Mew is an interesting SuddenGameplayChange and the character’s [[MoodSwinger mood swings]] may look funny at first, but then you realized how troubled she truly is: she is the ghost who used to possess the Mad Dummy, she found a new body which she considers her true self, and she tries to fuse with it by the only way she knows how: anger and violence.

* However, as the fight goes on, she doesn’t manage to fuse, grows distressed, and asks herself if something’s wrong with her.

** Even if the epilogue that follows is PlayedForLaughs, [[KickTheDog destroying the doll]] is a dick move: for the first time of her life, the ghost may have found happiness, and you take it from her. You can’t blame her for being pissed off.
* A bit of FridgeSadness here: even her sudden epiphany, where she asks your character to show her what love is, has darker implications: Mad Mew Mew’s JerkAss tendencies when she was Mad Dummy, which were only used as ComedicSociopathy, may be the only way she knew how to interact with people.
* Another detail: Mad Mew Mew isolated herself so she could fuse with her new body. Even if it makes her happy, she may actually fear other people’s reactions.

** Even if this is PlayedForLaughs, [[KickTheDog destroying the doll]] actually is a really hard move: for the first time of her life, the ghost may have found happiness, and you take it from her. No wonder she leaves more pissed than ever.

!!!Nintendo Switch Bonus Boss
The bonus boss of the Nintendo Switch version may look like a silly fight against a CatGirl, but it has much deeper implications.
* First, when you arrive at the Dog Shrine: if you played the UsefulNotes/PlayStation4 version and made the room full of life, seeing all its stuff used and broken can be depressing.
* The fight against Mad Mew Mew is an interesting SuddenGameplayChange and the character’s [[MoodSwinger mood swings]] may look funny at first, but then you realized how troubled she truly is: she is the ghost who used to possess the Mad Dummy, she found a new body which she considers her true self, and she tries to fuse with it by the only way she knows how: anger and violence.
--> "As soon as I saw this body, I just knew --\\
[[TransTribulations IT WAS ME!!! ME!!! ME!!!!]]"
* However, as the fight goes on, it doesn't work, and she starts to believe that she will never be the person she wanted to be.
--> "Enough. ENOUGH. ENOUGH!!!\\
WHY ISN'T IT WORKING!?\\
NO MATTER HOW MAD I GET,\\
NO MATTER HOW MUCH I FIGHT,\\
I JUST CAN'T FUSE WITH THIS BODY!!!\\
WHAT AM I DOING WRONG!?!?\\
[[DespairEventHorizon What am I doing wrong...]]"
* A bit of FridgeSadness here: even her sudden epiphany, where she asks your character to show her what love is, has darker implications: Mad Mew Mew’s JerkAss tendencies when she was Mad Dummy, which were only used as ComedicSociopathy, may be the only way she knew how to interact with people.

--> '''Alphys:''' God, I miss everyone. Now that they're gone, [[ItsAllMyFault it... it feels so clear what I should have done. What I should have said]]. Undyne... Asgore... Mettaton... at least Sans is here. He's... he's a good guy. And with him around, I... (''sigh'') You know. Just daydreaming here, but... [[YouBastard I really should have killed you when I had the chance]].

The fight with Asgore in the Neutral path is a hard moment for him. He starts by offering you tea, with a sad smile and saying it was nice to meet you. Then he averts his gaze and [[InterfaceScrew destroys the Mercy option so that you cannot spare him]]. Throughout the fight, [[HiddenEyes he refuses to make eye contact with you]]. However, you can still talk to him, and he will react to it, ultimately lowering his attack and defense, which shows that he actually doesn't want to harm you, but feels that there's no other way. If you bring Toriel's pie all the way to this fight and use it, the smell will remind him of Toriel, further reducing his attack and defense. The theme music that plays during the fight, "ASGORE", combines powerful orchestral segments with parts that sound melancholic and desperate, adding to the tragic atmosphere of the scene. And when you finally defeat Asgore, the Mercy command gets rebuilt, and choosing it makes Asgore talk about how you could all be happy together, giving a glimmer of hope... Which is immediately and mercilessly stomped on by Flowey, who attacks Asgore by surprise, either killing him and destroying his soul or destroying what's left of him if you don't choose mercy.

* There's also the fact that Sans boss fight is a HopelessBossFight; not for you, but for him, and in more ways than one. Even if he kills you (and [[ThatOneBoss he most certainly will the first few times, if not several]]), you can always just reset and try again. Even if you don't reset; nay, even if you ''couldn't'' reset anymore, what exactly does he have left to look forward to? Everyone he ever called a friend is now dead (except Alphys, and ''possibly'' Asgore, but even then it's ambiguous what sort of relationship the two may have had), any hopes of returning to the surface have been stripped away, and he is left practically all alone with no one left to help him. Being Sans in the No Mercy run ''[[TheChewToy sucks!]]''

* The fight against Mad Mew Mew is an interesting SuddenGameplayChange and the character’s [[MoodSwinger mood swings]] may look funny at first, but then you realized how troubled she truly is: she is the ghost who used to be inside the Mad Dummy found a new body which she considers her true self, and she tries to fuse with it by the only way she knows how: anger and violence.
---> "As soon as I saw this body, I just knew --\\

---> "Enough. ENOUGH. ENOUGH!!!\\

* While it looks like a silly bonus battle against a funny CatGirl, the Mad Mew Mew battle actually has darker implications.
** For context, the ghost inside the Mad Dummy found a new body which she sees as how she really is, as she tries to fuse with it by the only way she knows how: anger and violence.
---> "As soon as I saw this body, I just knew --\\
[[TransTribulations IT WAS ME!!! ME!!! ME!!!!]]"

!!!True Lab
* Alphys's backstory, revealed once you get to the True Lab. Apparently she was under so much pressure to get her Determination experiments right that she turned the bodies of dead monsters into living abominations fused together in agony. She had to lie to the families of these monsters and became so depressed over the situation that she shut herself in, lived in garbage, and was on the verge of suicide before meeting [[SugarWiki/HeartwarmingMoments Undyne]].
* In this exact place, you discover Video Tapes of Asgore and Toriel being excited for Toriel's pregnancy, The fallen child (who likely has a name you chose to represent yourself) and Asriel bonding like siblings, Asriel talking about how they accidentally poisoned their father with buttercups before the fallen child tells to turn off the camera, Asriel being extremely uncomfortable with "the plan" but going through with it for the fallen child's sake, and finally the fallen child on their death bed from [[DrivenToSuicide self-inflicted buttercup poisoning]]. Alphys's (or Gaster's...?) notes add to the tears on the nearby console as it sounds like she's (he's) protecting Asgore.
-->'''Entry 4''' : I've been researching humans to see if I can find out any info about their SOULS. I ended up snooping around the castle... And found these weird tapes. I don't feel like ASGORE's watched them... [[AwfulTruth I don't think he should.]]
* Alphys' journal entries say that she doesn't want to finish building Mettaton's body because she's worried that if she does, he won't hang out with her anymore. It's pretty depressing by itself, but given that she hardly has any friends to start with...
* In the True Lab, one of the Amalgamations — the one who hides in the form of a fridge — can be identified as the Snowdrake enemy's mother, at least as the primary consciousness. It can barely make an effort to attack you. Joking with it causes her to remember a part of herself, and should you 'Laugh' at the joke you told afterwards, you get this bit of dialogue.
--> ''You laugh, and [[LaughingMad keep laughing. It's SO funny, you can't stop. Tears run down your face]]. ... what? You didn't do that?''
--> '''''It's so cold.'''''
--> '''''sn...o...wy...'''''
** When you first see her "snowy" mumblings, you may assume that she's talking about her home, Snowdin. However, speaking to a green Snowdrake on Snowdin road reveals that he and his friends live in the forest and eat the lunches their parents bring them, but mentions that they share their lunches with "''Snowy''" since his parents aren't around. In the midst of losing her mind to the sixteen other monsters, she still has enough consciousness to remember her son without having to be reminded of him, unlike the other amalgamates.
** The Snowdrake amalgamate also has their own [[https://www.youtube.com/watch?v=K-EHmQHUwB8 unique battle music]], which is a broken version of the Snowdin Road theme that's been sporadically slowed down and sped up in random places. It fits the monster very well.
** The resulting text from attempting to laugh is an indication that you aren't in full control of the human's actions at that point as they refuse to laugh. They're so sympathetic for the poor amalgamation that they refuse to do anything that might hut their feelings.
* Another one of the Amalgamations, Lemon Bread, becomes this if you buy the 'Mystery Key' from Catty and Bratty and enter Napstablook's cousin's house. Its primary consciousness is Shyren's sister, who had "fallen down" and contributed to Shyren's timid personality. When it speaks, the words fill up the screen in [[VoiceOfTheLegion many separate text boxes]], saying things like "Welcome to my special hell" and "[[ArcWords But nobody came]]". It can hardly move, and you spare it by singing Shyren's song, reminding her of her sister.
* Rounding out the Amalgamates is Endogeny. If you're at all a dog person, this one's going to ''hurt.'' The only way to end the encounter is to try to comfort and play with the bounding, blob-like dog monster. The fact that ending the encounter plays a slower version of the cheerful Dogsong, proving that there's still a dollop of delightful doggo in Endogeny, makes it hurt even more. What's more, the somewhat off-kilter tempo of Dogsong, which ordinarily lends it a goofy, jovial tone, makes it actually sound a little sad when slowed down — it ends up emphasizing that this big, weird, blobby dog is most likely in constant pain, but smiling through it all.

-->'''Asgore''': I just wanted everyone to have hope... But...\\

* The fight with Asgore in the Neutral path. He starts by offering you tea, with a sad smile and saying it was nice to meet you. Then he averts his gaze and [[InterfaceScrew destroys the Mercy option so that you cannot spare him]]. Throughout the fight, [[HiddenEyes he refuses to make eye contact with you]]. However, you can still talk to him, and he will react to it, ultimately lowering his attack and defense, which shows that he actually doesn't want to harm you, but feels that there's no other way. If you bring Toriel's pie all the way to this fight and use it, the smell will remind him of Toriel, further reducing his attack and defense. The theme music that plays during the fight, "ASGORE", combines powerful orchestral segments with parts that sound melancholic and desperate, adding to the tragic atmosphere of the scene. And when you finally defeat Asgore, the Mercy command gets rebuilt, and choosing it makes Asgore talk about how you could all be happy together, giving a glimmer of hope... Which is immediately and mercilessly stomped on by Flowey, who attacks Asgore by surprise, either killing him and destroying his soul or destroying what's left of him if you don't choose mercy.
** Possibly even worse if this is another playthrough, and in the last one you killed Flowey (or if you spared him and got him to promise not to kill Asgore). He'll still give that same glimmer of hope... but he'll dismiss it, saying it's just impossible at this point. And then he'll force you to take his soul by [[DrivenToSuicide killing himself]]. [[YankTheDogsChain And]] ''[[YankTheDogsChain then]]'' [[YankTheDogsChain Flowey destroys his soul]].
** The lead-up to that fight as well, Asgore is nervous and heartbroken at the prospect of having to kill a child on his own. He spends the entire walk up to the final area doing his best to comfort a child on their way to their own execution (even making awkward small talk), trying to help the child cope with impending death in terms they can understand like being nervous about going to the dentist. At the end, he patiently waits until you are ready to get it over with. After the fight itself, he outright states that he doesn't care at all about power or revenge — he just wants his wife and son back.
** One of the least noticed but most powerful details of the fight: no matter how low your HP is, Asgore's attacks will NEVER kill you unless you have 1 HP left. On top of that, with 80 ATK and DEF, if he put his all into it, he could probably one-shot a low level Frisk with EASE, but he only does a little bit more damage than the average monster. He stalls as much as physically possible, holding back as much as he can, and only kills you when he has literally no other options.
--->'''Asgore:''' ...I so badly want to say, "would you like a cup of tea?" But... You know how it is.\\

*** Then as you keep restarting the fight, the last sentence will change to "He nods grievously." and finally "He nods pitifully."

** Before the fight, there's a save point in every single room, even though they're completely unnecessary as nothing really happens until the final showdown. It's possible that the Fallen Child really doesn't want to fight either and has to work up ''a ton'' of determination in order to confront their adoptive father. If the hand-knit sweater reading "Mr. Dad Guy" is any indication, Chara likely had a strong bond to Asgore in life. Note that these save points do not appear on the Genocide path.
*** Heck, at this point, put yourself in Chara's place. You cared for the one family implied to show you any kindness, tried to free them and everyone they cared about through ''killing yourself'' to cross the barrier and free them while getting revenge on humanity at the same time. Your plan failed horribly, and now you and this human you're stuck with have to kill your adoptive father, and you can think of ''no other way'' for you to get out of this situation. There's no advice you ''can'' give or ''want'' to give, and all you can do is watch on silently while this human makes the decision to kill or die to one of the monsters who showed you love.

* After you've defeated Photoshop Flowey and if you decide to spare the little flower, he repeatedly tells you that he hasn't changed or learned anything, and he'll keep coming back and keep killing. If you continue to spare him, his NightmareFace fades away as he starts to break down and cry:
-->'''Flowey:''' ... why? ... why are you being... ... so nice to me? I can't understand. [[EvilCannotComprehendGood I can't understand! I just can't understand...]]

** He has a [[FreudianSlip smaller breakdown]] after he reloads back to full health, though it's easy to miss until you learn his backstory:
--->'''Flowey:''' Call for help. I dare you. Cry into the darkness! "Mommy! Daddy!" "Somebody help!" See what good it does you!
** Flowey's screaming VillainousBreakdown as the [=SOULs=] betray him is a tearjerker, as his dialogue resembles a temper tantrum. It's a cold reminder that, despite everything, deep down, Flowey is ''[[WasOnceAMan still a child]]''.
--->'''Flowey:''' NO!! NO!!!!! YOU CAN'T DO THAT!!! YOU'RE SUPPOSED TO OBEY ME!! STOP!!! STOP IT!!!!! '''''STOOOOPPPP!!!!!'''''

* At the very end of [[ThatOneAttack his penultimate attack]], before he uses his special one, Sans [[NoHoldsBarredBeatDown absolutely loses it, and desperately slams you into the sides of the Bullet Board over and over again, his eye flashing with blue rage]]. He completely abandons the cold precision of his prior attacks. He has ''nothing'' left. No more patterns. No more Blasters. No more strength. No more strategy. No more Mercy. His only hope of survival is to mindlessly slam you again and again into the walls in a last-ditch attempt to end it before it's too late. But to no avail. Once you manage to survive that, it's over. You know it, and ''he'' knows it. His "special attack" will only stall you. It's the end for him.
** Worst of all, the penultimate attack actually cannot kill you, even if your life is already at 1. No matter how hard Sans tries now, he has no chance of actually winning once he whips that out.
* The No Mercy Path ending. Where to start?... After killing every possible enemy and Boss in the game, including the aforementioned and ultra-difficult Sans battle, Asgore is seen talking to a crying Flowey before greeting you. You're so far gone at this point, '''''Asgore's own brain doesn't even register you as human'''''. You immediately start a fight with him, despite him wanting to resolve things peacefully, and cut him down before Flowey finishes him off out of desperation to please you. Once he sees you're unimpressed, [[VillainousBreakdown he tearfully begs for his life before]] '''being brutally hacked to pieces.''' Chara then turns towards you, congratulating you for your hard work, before erasing the entire game world, leaving an empty void where there used to be The Friendly RPG Where No One Has to Die.
** Even the [[LastSecondChance last-second stop]] of No Mercy is heart-wrenching to say the least. You try to avoid killing Mettaton NEO, and in his last moments, he realizes you were motivated either by fear of monsters or simply didn't have enough hatred to be utterly evil. This one good-ish action results in Dr. Alphys surviving[[note]]By way of evacuating herself and several other survivors of the massacre to the True Lab, which meant they had to learn the AwfulTruth about the Amalgamates and Alphys' [[PlayingWithSyringes unethical experiments with Determination]].[[/note]] to become the new Queen... and she's in a complete HeroicBSOD, cursing her cowardice for not killing you when she had the chance and mourning her friends. It's made even worse in how she opens the call to the player by simply and coldly [[WhatTheHellPlayer stating that she hates them]].
--> '''Alphys:''' God, I miss everyone. Now that they're gone, [[ItsAllMyFault it... it feels so clear what I should have done. What I should have said]]. Undyne... Asgore... Mettaton... at least Sans is here. He's... he's a good guy. And with him around, I... (''sigh'') You know. Just daydreaming here, but... [[YouBastard I really should have killed you when I had the chance]].
** Flowey's brutal death is even worse if you know his true identity. In fact, when Flowey tearfully begs you not to kill him, Flowey's VoiceGrunting and face changes '''to Asriel's''' right before you kill him. If you're doing a No Mercy run after having completed a Pacifist run, where Asriel's character is explained, expect to feel nothing but misery.

[[OOCIsSeriousBusiness What am I doing wrong...]]"

* In any ending where the player didn't befriend Undyne, it's heavily implied that Alphys died, possibly [[DrivenToSuicide killing herself]] because of the weight of her past actions and [[ShrinkingViolet her trouble to socialize with people]]. To make things worse, the only ending where she's certainly

*** "You can't regret hard choices your whole life, right? Well, [[YourDaysAreNumbered not that I have much of a life left]]. But that's beside the point."

----> '''Papyrus:''' IT PAINS ME TO SAY THIS, BUT... YOU SHOULD PROBABLY NEVER COME BACK HERE. IF YOU DO, UNDYNE WILL DEFINITELY DESTROY YOU. NOT EVEN THE QUEEN CAN STOP HER. SO, UH... GOODBYE FOREVER. I'LL MISS YOU, MY FRIEND.

---> '''Sans:''' or maybe she's not feeling anything at all...? you'd better watch yourself, kid. things are lookin real bad for you.

---> '''Sans:''' i bet you're wondering why i'm not the ruler. eh. i'm not cut out for something like that. i like to take it easy, you know? ... that's a joke. [[ItsAllMyFault this is what happens when people like me take it easy]].\\
(additional lines if you killed 20 common monsters alongside the main bosses) hey, at least [[DeadlyEuphemism things are less crowded]]. 'cause of all the people you killed. [[YouBastard hope that was a good experience for you]]. ...just kidding. i don't really hope that. [[TranquilFury go to hell]].

* After you finish a neutral run, Sans calls you on your cell phone to tell you how the underground is doing. The contents of this call change depending on who you've killed during the game (if anyone). The worse endings can make you feel guilty. Even the better endings have some bittersweet element. The music that plays during this phone call is rather melancholic; it can make certain endings more heartwrenching.
** If you befriend Papyrus, Undyne, and Alphys, you will get the best possible neutral ending. Everyone is getting along and holding onto hope, thanks to you. However, Flowey tells you that, despite everything, your happy ending did not come, then [[HopeSpot offers you a chance to go back, as your journey is still not over]]. This heavily implies that Frisk dies in this ending; the Underground is a better place thanks to Frisk, but Frisk will never get to see the fruit of their sacrifice.
** If you spare all the major bosses but fail to befriend Undyne, she loses her job and her house and has to live with Sans and Papyrus. Because she hasn't gotten to really know you, she blames you for the disappearance of Asgore.
*** If you kill only Mettaton, Undyne is heavily implied to hit the DespairEventHorizon, since Alphys has also disappeared. Even when Papyrus suggests that they could plot revenge on you (just so he can see you again), it only prompts her to reply that it "[[OOCIsSeriousBusiness won't bring anybody back.]]" Remember, it's '''[[HotBlooded Undyne]]''', of all people who said that! Papyrus then pleads that you bring Undyne's friends back for her sake.
*** If you kill ''anyone'' (besides Mettaton) after befriending Undyne, she feels so hurt and betrayed and wonders why she ever let herself become friends with you. Papyrus delivers quite possibly his most heart-wrenching line in the entire game. He even appears as if he's about to cry-
---->'''Papyrus:''' IT PAINS ME TO SAY THIS, BUT... YOU SHOULD PROBABLY NEVER COME BACK HERE. IF YOU DO, UNDYNE WILL DEFINITELY DESTROY YOU. NOT EVEN THE QUEEN CAN STOP HER. SO, UH... GOODBYE FOREVER. I'LL MISS YOU, MY FRIEND.
** If you killed Papyrus, Undyne, or more than ten monsters, Toriel tries to rule and enact a policy which humans that end up in the Underground are treated as friends. Nobody is in favor of this, and she ends up having to return to the Ruins. Fortunately, Sans keeps her company.
*** If you spared Undyne, she spearheads the rebellion and banishes Toriel back to the Ruins before assuming the throne herself, more driven to destroy humanity than Asgore was. If you killed Undyne, Toriel resigns from her position to stop a coup d'état, and returns to the Ruins while the Underground falls into anarchy.
*** If you killed Papyrus, Sans mentions that Toriel still wants to see you again, but Sans doesn't have the heart to tell her that, because she protected you, you went on to murder his brother. He finishes up by curtly informing you that you're not welcome in the underground again and that you should never come back.
** If you kill Toriel but spare Undyne, Sans mentions that Toriel hasn't answered him. If you also killed Papyrus, Sans addresses the possibility that you killed Toriel.
--->'''Sans:''' or maybe she's not feeling anything at all...? you'd better watch yourself, kid. things are lookin real bad for you.
** If you killed Toriel and Undyne, Mettaton takes the throne. Though his dialogue is mostly lighthearted, he starts to break character when he mentions some of the kingdom's problems. He regrets how he treated Alphys and laments not being able to find her to apologize and ask her to rule with him. He creates a statue of her in her memory. Also, if you spared Papyrus, Mettaton lets him talk to you. Papyrus mentions that Undyne went missing, notes that people who don't like Mettaton's show tend to disappear, and seems to believe that Mettaton is responsible for Undyne's disappearance. Papyrus has no idea that ''you'' killed Undyne.
** If you kill every boss except Papyrus, he leads the underground since there is nobody else left to lead, but he laments that he misses his friends. To make things worse, Sans told him they all went on an extremely long vacation, as he doens't have the courage to tell him the truth: when you know Papyrus, you can legitimately wonder if he is clueless and will worry more and more about why they don't come back, or actually understand his brother's DeadlyEuphemism and resort to denial in order to cope with the sad reality.
** If you kill ''all'' the bosses and at least one other monster (without carrying a No Mercy run into Hotland), Sans' call is ''very'' creepy. The Underground falls into chaos as everyone gives up hope. To make things even worse, Sans himself clearly feels a touch of guilt over what happened:
--->'''Sans:''' i bet you're wondering why i'm not the ruler. eh. i'm not cut out for something like that. i like to take it easy, you know? ... that's a joke. [[ItsAllMyFault this is what happens when people like me take it easy]].
--->'''Sans:''' (if you killed 20 common monsters alongside the main bosses) hey, at least [[DeadlyEuphemism things are less crowded]]. 'cause of all the people you killed. [[YouBastard hope that was a good experience for you]]. ...just kidding. i don't really hope that. [[TranquilFury go to hell]].
** Just the fact that in the endings where the player has killed Undyne and/or Mettaton, Alphys disappears, with the strong underlying implication that the loss of them has resulted in her being DrivenToSuicide. Just let that sink in.
*** Should Mettaton become King at the end of a neutral run, he spends most of the call gloating about how his television show seems to have become popular across the whole Underground (that was almost devastated by your actions), but when he brings up Alphys, he seems genuinely upset about not having known where she had gone. It's also heavily implied that his decision to turn the Underground into a massive {{Egopolis}} is just to cover his pain and misery he gained from finding out the truth.
** If you fail a Genocide Run at the Core, forcing it back into a Neutral Run with almost everyone dead, Alphys takes the throne. The first thing she says to you over the phone? ''"I just called to tell you. '''[[WhamLine I hate you.]]'''"''. Not only is it so jarring to see from a normally very friendly ShrinkingViolet like her, it gets even worse when she mourns all of her deceased friends and fellow monsters whom you killed: hoping that [[SuicideByCop eventually, you would get her as well]] before Undyne's dying words (stated by her to be told in "[[OOCIsSeriousBusiness crazed desperation]]") made her realise that she had to evacuate the survivors to [[PlayingWithSyringes the True Lab]] and protect them, even if it meant them learning [[LiarRevealed the truth about her.]] She closes by musing ironically on the whole situation, that [[ForWantOfANail she could have saved everyone]] simply by [[CombatPragmatist killing you when she had the chance.]]
-->'''Alphys''': God... I miss everyone. Now that they're gone, [[ItsAllMyFault it... It feels so clear what I should have done. What I should have said.]]

-->"B-but I never got to...!" *BOOM*

-->'''Undyne:''' What!? No, we just became friends!! You can't already be that close...

* So Sorry's self-deprecation and death can be depressing. The RealitySubtext is even sadder: the character managed to get into the game because the owner of the character bought a $1,000 Kickstarter goal because he wanted to support Toby's game. Toby arranged that So Sorry be a secret character because Toby wanted to avoid controversy with the character... but, once Undertale's popularity exploded, his appearance became wide open. A lot of controversy happened because of the "furry fetish" character being in the game to the point of rumours forming that So Sorry can be killed without gaining EXP or ruining a Pacifist run. Add how the owner actually has depression and was bullied in his life, and...
* Killing Muffet. After she dies, a tiny spider wanders to where she was, before scuttling off screen. It then comes back [[TheTragicRose holding a rose, and slowly and gently places it down on the spot where she died before leaving the screen]]. It's as heartbreaking as it sounds.
** Oh, but it gets worse. If you kill Muffet, you know what you get? Exactly the amount of Gold you paid her during the fight (which can easily be zero). Muffet was telling the truth all along. She really did need that money...
* If you want to be ''really'' monstrous, you can let the two Royal Guards get together during the fight, and ''then'' kill them. Watching the survivor's reaction after the first one dies will make you feel completely awful.
** Killing 01 first only results in 02 saying "...! [[YouExclamation You!]]" but if you kill 02 first...
--->"02... I never told him..."
"01 holds his head in his hands."

-->'''Sans''': if you have some sort of [[gold:special power]]... isn't it your responsibility to do the right thing? \\

** If you kill every boss except Papyrus, he leads the underground since there is nobody else left to lead, but he laments that he misses his friends. Papyrus is innocent enough to believe that Undyne and the others were on an extremely long vacation. An alternative interpretation is that he is fully aware of what happened them, but he has resorted to denial in order to cope.

--->'''Sans:''': i bet you're wondering why i'm not the ruler. eh. i'm not cut out for something like that. i like to take it easy, you know? ... that's a joke. [[ItsAllMyFault this is what happens when people like me take it easy]].
--->'''Sans:''' (if you killed 20 common monsters) hey, at least [[DeadlyEuphemism things are less crowded]]. 'cause of all the people you killed. [[YouBastard hope that was a good experience for you]]. ...just kidding. i don't really hope that. [[TranquilFury go to hell]].

--->'''Flowey''': Clever. Verrrryyy clever. You think you're really smart, don't you? In this world, it's "kill or be killed". So you were able to play by your own rules. You spared the life of a single person. [[GigglingVillain Hee hee hee...]] But don't act so cocky. [[ParanoiaFuel I know what you did.]] You murdered her. And then you went back, because you regretted it.
** If you insist on [[SheatheYourSword sparing Toriel]], it'll take you a while before she can get over her loneliness, fear, and doubts to let you have your way. But not without a FinalFirstHug, after which she politely -- but firmly -- tells you not to come back, which can make a player feel horrible even on a Pacifist run, as she will just disappear and never even once pick up the phone until the Golden Ending where she gleefully enjoys sending you messages. Though the tearjerkiness kinda loses its impact if you find out that the annoying dog has her phone.

--->'''Toriel:''' Now I see who I was protecting by keeping you here. Not you... But them!!! Ha... ha...

--->'''Toriel''': You... ... at my most vulnerable moment... To think I was worried you wouldn't fit in out there... Eheheheh!!! You really are no different than them! Ha... ha...
** Toriel's battle theme is called "Heartache", and it fits perfectly since you broke her heart before the fight.[[note]]It's not the child who has the moral capacity to spare or kill her that has a heartache. ''Toriel'' is the one with the heartache because she cared for you and took you in. Now she has to fight you. Her heart is ''aching'' the entire battle, no matter what the outcome.[[/note]] This becomes doubly heart-wrenching when you discover near the end of the game that she lost both her own child and her adopted child at the same time many years ago, along with seeing potentially ''six'' other human children getting killed when they also tried to return home. It's no surprise, then, that she tests you so brutally to see if you are strong enough to survive on your own.

** If you kill ''all'' the bosses and at least one other monster (without carrying a No Mercy run into Hotland), Sans' call is ''very'' creepy. The Underground falls into chaos as everyone gives up hope. To make things even worse, Sans himself clearly feels a touch of guilt over what happened, as he says that things like this happen when people like him take it easy.
--->'''Sans:''' hey, at least things are less crowded. 'cause of all the people you killed. [[YouBastard hope that was a good experience for you]]. ...just kidding. i don't really hope that. [[TranquilFury go to hell]].

-->''...so... guess that's it, huh? ...just... [[IWarnedYou don't say i didn't warn you.]]''
-->''...welp. i'm going to grillby's.''
-->''papyrus, do you want anything?''

--->'''Sans:''' if we're really friends... you won't come back.

--->'''Sans:''' you can't understand how this feels. knowing that one day, without any warning... it's all going to be reset.

-->'''Sans:''' woah, you look REALLY pissed off. heheheh... did i getcha? [[DisappointedInYou well, if you came back anyway... i guess that means we never really WERE friends, huh?]] heh. don't tell that to the other sans-es, ok?

-->"please, if you're listening... let's forget all this, ok?"

-->'''Alphys:''' God, I miss everyone. Now that they're gone, [[ItsAllMyFault it... it feels so clear what I should have done. What I should have said]]. Undyne... Asgore... Mettaton... at least Sans is here. He's... he's a good guy. And with him around, I... (''sigh'') You know. Just daydreaming here, but... [[YouBastard I really should have killed you when I had the chance]].

* Once you've gone through the No Mercy ending, you will never be able to get the GoldenEnding again. ''[[PermanentlyMissableContent Ever.]]'' If you try for either one, the Fallen Child will simply remind you that they're in possession of Frisk's soul, and thus can destroy their happy ending at any time. Not even an uninstall and reinstall will reverse this; and it's ''[[YouBastard your]]'' curiosity and pursuit of OneHundredPercentCompletion that caused all of this. You can do a little trickery on the computer versions to undo this. For the [=PS4=], Vita, Switch, or Xbox One versions, this can only be undone by completely deleting its save data from the console storage.

--->"Huh? What are you doing...!? Wh... What did you do...? What's this feeling...? What's happening to me? No! NO! I don't need ANYONE! STOP IT! Get away from me! Do you hear me!? I'll tear you apart!\\

--->'''Asriel''': Frisk...[[ButNowIMustGo I have to go now]]. [[PowerIncontinence Without the power of everyone's souls...I can't keep maintaining this form. In a little while...I'll turn back into a flower]]. I'll stop being "myself." I'll stop being able to feel love again. So... Frisk. It's best if you just forget about me, OK? Just go be with the people who love you.
---->❤ [[AC:Comfort him]]\\

--->''(Frisk walks over to Asriel and hugs him. Asriel hugs back, while Frisk rubs his back)''\\

--->"Yo... Uh... Don't talk to me."

** If you're going for the No Mercy route, it becomes a SingleStrokeBattle, and ends with Toriel gasping and saying [[https://www.youtube.com/watch?v=JxfBP8zDhJQ#t=1136 "Y... you... really hate me that much...?"]]

* If the player has began a Genocide route, all of the monsters you encounter will make an attempt to fight back or will initiate a fight with you. And then when it's time to fight [[AllLovingHero Papyrus]], what's the first thing that happens?
-->'''Narrator:''' [[WhamLine Papyrus is sparing you.]]
** To expand upon this, killing Papyrus can be a heartrending introduction to the full game's path of No Mercy. Instead of fighting, he offers to become friends, reasoning that you are simply alone. You kill him with one shot. After that... he still believes in you. His final words are his telling you he knows you can be good if you try, before finally turning to dust.
*** If you kill Papyrus on Neutral and go back into Snowdin, the [=NPCs=] will remark that the atmosphere of the town feels "off" all of a sudden. Arguably the worst part is that the patrons of Grillby's will wonder why Sans hasn't come in for lunch yet, and the bear at the gift tree will say that a box for Papyrus has gone missing. [[HeroicBSOD Bear in mind that Sans is the only one who knows what happened at this point.]]
*** It's even worse when you realize that Pacifist!Undyne spoke the literal truth when she said he'd get ripped into little smiling shreds.
*** Even worse is that when you're inside Grillby's, there's no music whatsoever. Keep in mind that even in the Genocide route, Sans' theme would always be playing when you're at Grillby's. As minor as this detail is, it really makes Sans' HeroicBSOD all the more effective.

-->''"They must be here, playing a joke on me. I'll just wait until one of them admits it..."''

--->'''Snowdrake:''' [''if the player responds well to his jokes''] See!? Laughs! Dad was wrong!

-->"Please don't hurt my family."

-->"ALLOW ME TO TELL YOU ABOUT SOME COMPLEX FEELINGS. FEELINGS LIKE... THE JOY OF FINDING ANOTHER PASTA LOVER. THE ADMIRATION FOR ANOTHER'S PUZZLE-SOLVING SKILLS. THE DESIRE TO HAVE A COOL, SMART PERSON THINK YOU ARE COOL. THESE FEELINGS... [[BlatantLies THEY MUST BE WHAT YOU ARE FEELING RIGHT NOW]]!!! I CAN HARDLY IMAGINE WHAT IT MUST BE LIKE TO FEEL THAT WAY. AFTER ALL, I AM VERY GREAT. [[SuspiciouslySpecificDenial I DON'T EVER WONDER WHAT HAVING LOTS OF FRIENDS IS LIKE.]]"

* You'd think that killing the Mad Dummy on a No Mercy run would be something to look forward to, right? Well, when you approach it, it will become corporeal — its lifelong dream — and instead be known as the ''Glad'' Dummy. It's so hard to kill it when it's finally become so happy.
** Now knowing that the Mew Mew doll body would end up being the true body she desires, theres also the idea of the ghost permanently fusing with a body that they would ultimately not like anymore.

* Another one of the Amalgamations, Lemon Bread, becomes this if you buy the 'Mystery Key' from Catty and Bratty and enter Napstablook's cousin's house. Its primary consciousness is Shyren's sister, who had "fallen down" and contributed to Shyren's timid personality. When it speaks, the words fill up the screen in [[VoiceOfTheLegion many separate text boxes]], saying things like "Welcome to my special hell" and [[ArcWords "But nobody came"]]. It can hardly move, and you spare it by singing Shyren's song, reminding her of her sister.

** Going through New Home on a No Mercy run has Chara personally recognize a lot of their childhood items. When you check the family photo, they have nothing to say, "...".

[[folder:Genocide Final Boss and Ending]]
* The battle with Sans on the Genocide path. After a long, hard, gruelling battle, Sans realizes that he can't beat you, so he simply does nothing but never use his turn. But if you wait long enough, he falls asleep from exhaustion — the Player can then move the entire box over to the Fight menu to finish him off. Sans dodges the attack, beginning to boast — only to dodge into and be struck with another fatal slash across the chest. Sans painfully coughs up blood (or ketchup?) and then [[TheDyingWalk very slowly saunters away]], making sure to [[DueToTheDead ask his deceased brother if he would like anything to eat]] before he finally dies off-screen.
-->''...so... guess that's it, huh? ...just... [[IWarnedYou don't say i didn't warn you.]]''
-->''...welp. i'm going to grillby's.''
-->''papyrus, do you want anything?''
** What makes this battle even more heartbreaking is that, [[StepfordSmiler while Sans's trademark smile never falters,]] you can clearly see the anguish and exhaustion in his eyes, even before the fight begins. Reach the end of the fight, and he'll refuse to end his turn, knowing that as soon as he does, he's done for... so the only way to save everyone is to stall long enough for you to get bored.
** Sans' last words to you are sad in and of themselves. He's not giving you one last boast of hatred or defiance, he's not despairing over how he's failed to protect everyone, he just calmly accepts that he's failed and that you're going to bring the end of everything. Granted, it's hardly even surprising -- he's already taught himself not to care for a long time now.
** The most depressing thing of all, though, is how his sprite looks as you kill him. When you ''finally'' hit him, he looks as shocked as you might expect him to, his smile slipping — and then he falls down, SymbolicBlood starts coming out of his wound and mouth as he clutches his chest in pain, [[http://56.media.tumblr.com/d36a25ca2df0afba147d84db1314d11f/tumblr_inline_nzbhubMGfa1tepv7x_250.png and the way he looks at you and at his wound with that expression is absolutely heartbreaking]]. The fact he's ''still'' smiling as he stares at you with such anguish in his eyes that it looks like he's about to cry, will make you feel absolutely awful regardless of how many times you cursed him beforehand for [[ThatOneBoss how many times he screwed you over]].
*** To elaborate, yes, his smile does indeed ''slip''. Which is heartbreaking in and of itself, because it reveals that yes, [[StepfordSmiler Sans' smile is voluntary]]. Every moment of every reset, Sans is smiling. Forcing himself to keep a jovial, happy expression, even though he gave up a long time ago. Forcing a joke and smile just to get through the endless resets. It makes his character that much more tear-jerking, the fact that he smiles, not because he doesn't have a choice, but because it's his only way to cope with [[YouBastard the hell you put him through]].
** Immediately after [[ISurrenderSuckers "dunking"]] you, Sans also reveals his true bitterness and disappointment:
--->'''Sans:''' if we're really friends... you won't come back.
** This line:
--->'''Sans:''' you can't understand how this feels. knowing that one day, without any warning... it's all going to be reset.
*** To elaborate, Sans is the only person other than the human child who is aware of the resetting timelines. He simply [[AwesomenessByAnalysis reasoned it out between his research and from reading your expressions]]. That means that he knows that there is a happy ending, and that it can, has been, and will be, snatched away. In the same way, he has seen Genocide. He knows it can, has, and will happen. No wonder he has to force a smile. ''No wonder'' he's given up.
** Sans's attacks are beefed up versions of Papyrus' attacks — not a surprise, given their relationship. What is saddening is what can be extrapolated from them: the game states that a monster's thoughts can affect the form of their magic attacks. Check out the first proper attack of the battle — it's Papyrus' small bone rush attack, but paired with taller bones. We already know Papyrus' small bone rush shows up in his battle when he's thinking about his brother, which by extension means that the ''first'' thing that the boss is thinking about here is his brother and himself. The next attack after that is a sped-up version of Papyrus' tall light-blue bone/short white bone attack. Some fans have taken to calling the light blue attacks that can be avoided by non-movement 'ghost' attacks, which means that now Sans is thinking about Papyrus and himself again... except this time the tall bone is a 'ghost.' No wonder this battle is all TranquilFury and VideoGameCrueltyPunishment.
** Think about ''why'' Sans uses Papyrus's attacks. Even though Sans is older than Papyrus, he looked up to him and loved him dearly. Papyrus was also the one of them with proper fighting training. Not only had Sans most likely no idea how to fight without referring to what he knew from Papyrus, but by using Papyrus' attacks against you, [[ItsPersonal he wants to punish you double]] by reminding you that the coolest person in the world is dead, that it is ''your'' fault, and that you will die with the ironic fate of being killed by the very abilities of one of your early victims.
* If you get dunked on by Sans, reset and re-fight him, reach the mid-point where he offers to spare again, and then attack him, he notices how mad you look. Sans concludes that he successfully tricked you, before noting with [[MirthlessLaughter an unhappy chuckle]] that since you reset to try and kill him again after that, then you were never really his friend to begin with. And ends it by asking you to not “tell that to the other sans-es”, as if to say his alternate timeline selves would’ve been heartbroken to realize that you never really cared about him.
-->'''Sans:''' woah, you look REALLY pissed off. heheheh... did i getcha? [[DisappointedInYou well, if you came back anyway... i guess that means we never really WERE friends, huh?]] heh. don't tell that to the other sans-es, ok?
* One more note on the fight, Sans at the midpoint will say that somewhere, inside the player character, is the "memory of someone who wanted to do the right thing"... and ''pleads'' for them to remember him and abandon this. He knows about the "anomaly" (IE ''you''), and he can see Chara/The Fallen Child in front of him. He's not talking about ''either'' of you. ''[[IKnowYoureInThereSomewhereFight He's calling out to]] '''[[IKnowYoureInThereSomewhereFight Frisk]]'''.''
-->"please, if you're listening... let's forget all this, ok?"
** This brings his [[ISurrenderSuckers offer to "spare" you during the battle into another perspective]]; he wasn't trying to bluff Chara into letting their guard down, he was attempting to [[DyingAsYourself give]] ''[[DyingAsYourself Frisk]]'' [[DyingAsYourself one last opportunity to take over]], just long enough for Sans to [[RedemptionEqualsDeath end it on both their terms]].
* Everything Sans reveals about himself during the final battle with him is a pure, unadulterated marriage between FridgeHorror and TearJerker: imagine having to live with the knowledge that the universe you exist in can be manipulated on a whim by a God-like, all-powerful being who treats you and everyone in said universe like their own personal toybox. Imagine this being has the ability to either bless you with the perfect happy ending or brutally kill you and everything you love, [[AboveGoodAndEvil not out of any desire for good or evil]], but just because [[ItAmusedMe they're bored]]. Now imagine that being has the ability to reset the timeline you live in and erase all but the faintest memories of both these things; you know you're missing ''something'', but can never fully grasp what it is, just that it was taken from you as easily as it was given. Imagine gradually losing hope at trying to fight this power, until eventually you've been run into such a state of nihilism you have no choice but to [[StepfordSmiler force a joke and a smile everywhere you go just to make it through the day]]. Imagine never being able to confide in anybody about this because doing so would either mean burdening them with the same existential nightmare, or being treated as if you've lost your mind. Imagine living with the knowledge that your beloved little brother, [[LivingEmotionalCrutch the one thing in your life that truly makes you happy anymore]], is at the mercy of this being every time the world is reset. Imagine not even being able to fully numb yourself to the repeated anguish of his death, because you can never quite remember enough each time it happens. Now, as a cherry on top of all this misery, imagine that your only possible means of escape are entirely in the hands of this hedonistic god. If they don't feel like letting you keep your happy ending, nothing can let you leave, not even the cold embrace of death. Every time your heart stops beating, you suddenly find yourself thrust back to the beginning of it all, struggling to remember whatever it was that just happened. [[AndIMustScream Sans' life is a living Hell]], and if he never manages to get out of it, [[YouBastard there's nobody to blame but you]].
* There's also the fact that Sans boss fight is a HopelessBossFight; not for you, but for him, and in more ways than one. Even if he kills you (and [[ThatOneBoss he most certainly will the first few times, if not several]]), you can always just reset and try again. Even if you don't reset; nay, even if you ''couldn't'' reset anymore, what exactly does he have left to look forward to? Everyone he ever called a friend is now dead (except Alphys, and ''possibly'' Asgore, but even then it's ambiguous what sort of relationship the two may have had), any hopes of returning to the surface have been stripped away, and he is left practically all alone with no one left to help him. Being Sans in the No Mercy run ''[[TheChewToy sucks!]]''
* Chara becomes a victim too if you hold to the theory that they weren't actually a bad person. In a Neutral/Pacifist run, their narration can be enthusiastic, snarky, and even warm and loving. However flawed they may have been in life, they weren't a demon until you corrupted them into becoming one.
** It gets worse when you think about the Genocide Route from Chara's perspective. Imagine waking up after getting brutally murdered by the same humans you tried to get away from, in an attack that killed your adoptive brother and best friend, because of a [[ThanatosGambit plan you came up with]]. The plan that [[AllForNothing failed, meaning that you and your brother died for nothing.]] Now imagine being [[ForcedToWatch forced to follow this human as they indiscriminately slaughter everyone in their path, including your adoptive parents, your personal hero, and finally, your adoptive brother and best friend.]] With all the [[GainingtheWilltoKill LOVE they gained]] and the [[ConditionedtoAcceptHorror horrors they saw]], [[WoobieDestroyerofWorlds it's no wonder they chose to destroy the world.]] They have literally nothing left to live for.
** Even the interpretation that Chara, not Frisk, was responsible for the automated attacks on Asgore and Flowey becomes this if you believe that they loved (and perhaps still love) their family. Chara's corrupted narration has them [[TookALevelInJerkass start reacting coldly and dismissively early in the Genocide Route]], yet they still go quiet when checking the family photo next to their bed and they seem happy to be reunited with the Locket implied to have been given to them by Asriel. Consider that at the time, they are strongly implied to be soulless and also are at LV 19, just ''one'' level away from the max — but they fall silent over the family photo of happier times where "everyone is smiling." They're so far gone by the time you get them to LV 20 and lead them to Asgore that they'll attack him automatically, but even at LV 20, they [[MoralityPet seem to falter at Flowey crying with Asriel's face and voice]], and you have to step in again and choose to deal the first blow, leaving Flowey in shock and pain but still alive, before Chara suddenly jumps back in to finish him off. At this point, perhaps that's the only [[MercyKill "mercy"]] they can give him.
*** The encounter with Asgore is also saddening because in other routes, Frisk clearly reminds him greatly of Chara — he admits it before trying to give Frisk his SOUL to let them escape so they can free the Underground, before that spends his fight avoiding eye contact with them, and staring into his eyes causes him to remember Chara and helps save him as a Lost SOUL — but here, Chara has become so deeply corrupted from the person they'd once been that their own father doesn't recognize them as ''human'' anymore, much less as ''Chara.''
** Really, the absolute '''''cruelest''''' thing about the Genocide Route might just be how '''deeply''' you fuck up Chara with it. You take this kid the Underground had cherished, this child who had hope shining in their eyes and finds hope again if you don't kill anyone, who likes silly jokes and chocolate and playing in the mud with their brother and eating pies with their bare hands, who once killed themself to give their family and their people a shot at sunlight... and you turn them into THE villain of Undertale, an unfeeling, nihilistic, power-hungry OmnicidalManiac even Flowey is terrified of who's witnessed you hunt down and slaughter their family and their people, who's learned from you that people are nothing but ways to increase their stats, who's so far gone they actually ''thank you'' for what you did to them and call you their friend, and who ''can't'' be saved or turned back to who they were[[note]]at least without cheating by editing the game files[[/note]]. You think Asriel's fall from grace into becoming Flowey was tragic? Congratulations, ''you forced that on another kid.''
* In Sans's penultimate attack, at the very end, right before he uses his special one, [[NoHoldsBarredBeatDown he absolutely loses it, and desperately slams you into the sides of the Bullet Board over and over again, his eye flashing with blue rage]]. He completely abandons the cold precision of his prior attacks. He has ''nothing'' left. No more patterns. No more Blasters. No more strength. No more strategy. No more Mercy. His only hope of survival is to mindlessly slam you again and again into the walls in a last-ditch attempt to end it before it's too late. But to no avail. Once you manage to survive that, it's over. You know it, and ''he'' knows it. His "special attack" will only stall you. It's the end for him.
** Worst of all, the penultimate attack actually cannot kill you, even if your life is already at 1. No matter how hard Sans tries now, he has no chance of actually winning once he whips that out.
* The No Mercy Path ending. Where to start?... After killing every possible enemy and Boss in the game, including the aforementioned and ultra-difficult Sans battle, Asgore is seen talking to a crying Flowey before greeting you. You're so far gone at this point, '''''Asgore's own brain doesn't even register you as human.''''' You immediately start a fight with him, despite him wanting to resolve things peacefully, and cut him down before Flowey finishes him off out of desperation to please you. Once he sees you're unimpressed, [[VillainousBreakdown he tearfully begs for his life before]] '''being brutally hacked to pieces.''' Chara then turns towards you, congratulating you for your hard work, before erasing the entire game world, leaving an empty void where there used to be The Friendly RPG Where No One Has to Die.
** Even the [[LastSecondChance last-second stop]] of No Mercy is heart-wrenching to say the least. You try to avoid killing Mettaton NEO, and in his last moments, he realizes you were motivated either by fear of monsters or simply didn't have enough hatred to be utterly evil. This one good-ish action results in Dr. Alphys surviving[[note]]By way of evacuating herself and several other survivors of the massacre to the True Lab, which meant they had to learn the AwfulTruth about the Amalgamates and Alphys' [[PlayingWithSyringes unethical experiments with Determination]].[[/note]] to become the new Queen... and she's in a complete HeroicBSOD, cursing her cowardice for not killing you when she had the chance and mourning her friends. It's made even worse in how she opens the call to the player by simply and coldly [[WhatTheHellPlayer stating that she hates them]].
-->'''Alphys:''' God, I miss everyone. Now that they're gone, [[ItsAllMyFault it... it feels so clear what I should have done. What I should have said]]. Undyne... Asgore... Mettaton... at least Sans is here. He's... he's a good guy. And with him around, I... (''sigh'') You know. Just daydreaming here, but... [[YouBastard I really should have killed you when I had the chance]].
** Flowey's brutal death is even worse if you know his true identity. In fact, when Flowey tearfully begs you not to kill him, Flowey's VoiceGrunting and face changes '''to Asriel's''' right before you kill him. If you're doing a No Mercy run after having completed a Pacifist run, where Asriel's character is explained, expect to feel nothing but misery.
** During the final cutscene of the run, the Fallen Child takes control and kills Asgore and Flowey on their own, with no input from you, which can be NightmareFuel... but there's a single moment of reprieve from it. When Flowey reverts to Asriel's face and voice, and begs not to be killed, the Fallen Child falters. ''You'' have to push the button to prod them into finishing the job and brutally murdering their adoptive brother.
* Once you've gone through the No Mercy ending, you will never be able to get the GoldenEnding again. ''[[PermanentlyMissableContent Ever.]]'' If you try for either one, the Fallen Child will simply remind you that they're in possession of Frisk's soul, and thus can destroy their happy ending at any time. Not even an uninstall and reinstall will reverse this; and it's ''[[YouBastard your]]'' curiosity and pursuit of OneHundredPercentCompletion that caused all of this. You can do a little trickery on the computer versions to undo this. For the [=PS4=], Vita, Switch, or Xbox One versions, this can only be undone by completely deleting its save data from the console storage.
[[/folder]]

** "You tell ASGORE that you don't want to fight him. [[NecessarilyEvil His breathing gets funny for a moment."]]

*** This makes a depressing amount of sense that is even more tear jerking when you realize that Asgore is working up the courage to kill a child who is the spitting image of ''his own adopted child who committed suicide.''

*** If you kill only Mettaton, Undyne is heavily implied to hit the DespairEventHorizon, since Alphys has also disappeared. Even when Papyrus suggests that they could plot revenge on you (just so he can see you again), it only prompts her to reply that it [[OOCIsSeriousBusiness "won't bring anybody back."]] Remember, it's '''[[HotBlooded Undyne]]''', of all people who said that! Papyrus then pleads that you bring Undyne's friends back for her sake.

** If you fail a Genocide Run at the Core, forcing it back into a Neutral Run with almost everyone dead, Alphys takes the throne. The first thing she says to you over the phone? ''"I just called to tell you. '''[[WhamLine I hate you.]]'''"''. Not only is it so jarring to see from a normally very friendly ShrinkingViolet like her, it gets even worse when she mourns all of her deceased friends and fellow monsters whom you killed: hoping that [[SuicideByCop eventually, you would get her as well]] before Undyne's dying words (stated by her to be told in [[OOCIsSeriousBusiness "crazed desperation"]]) made her realise that she had to evacuate the survivors to [[PlayingWithSyringes the True Lab]] and protect them, even if it meant them learning [[LiarRevealed the truth about her.]] She closes by musing ironically on the whole situation, that [[ForWantOfANail she could have saved everyone]] simply by [[CombatPragmatist killing you when she had the chance.]]

*** It's hard to say what's more rare: finding a LetsPlay where someone picks [[AC:"Do Not"]] or finding one that doesn't get choked up at the aforementioned FinalFirstHug...

** An easily missed bit of fluff, but speaking to Gerson has him reveal that Asgore and Toriel are a special type of monster that can't grow old unless they have a child. When the player character asks if they would work as a surrogate child, the shopkeeper scoffs and assures them "If you were Asgore's child, he'd certainly [[OutlivingOnesOffspring outlive you."]] It puts a sobering twist on what seemed like a perfect ending.

-->''"Sorry, Blooky. My dreams can't wait for anyone..."''

-->(''mimicking Toriel'') "Where oh where could that child be...? I've been looking all over for them..." (''in Flowey's shaky, crazed voice'') ...Hee hee hee. THAT'S not true. [[ReplacementGoldfish She'll find another kid, and instantly forget about you. You'll NEVER see her again.]]
* If you kill Papyrus, Undyne ''will'' call you out for it. On top of that, [[OOCIsSeriousBusiness it's the only situation in which she doesn't engage in a]] HotBlooded [[OOCIsSeriousBusiness fight intro]]. Note that as she says that final line, she ''[[SlasherSmile smiles,]]'' clearly very eager to rip you apart after [[WhatTheHellPlayer what you've done.]]
-->"[[DispenseWithThePleasantries ...Forget it.]] Look. Papyrus didn't come to his meeting today.\\

...what did you do to him? What did you '''[[SuddenlyShouting DO TO HIM?]]'''\\

Go ahead. Prepare however you want. But when you step forward... (''smiles viciously'') [[TranquilFury I will]] '''[[TranquilFury KILL]]''' [[TranquilFury you.]]"

* Alphys's backstory, revealed once you get to the True Lab. Apparently she was under so much pressure to get her Determination experiments right that she turned the bodies of dead monsters into living abominations fused together in agony. She had to lie to the families of these monsters and became so depressed over the situation that she shut herself in, lived in garbage, and was on the verge of suicide before meeting [[SugarWiki/HeartwarmingMoments Undyne]].
* Also in the True Labs you discover Video Tapes of Asgore and Toriel being excited for Toriel's pregnancy, The fallen child (who likely has a name you chose to represent yourself) and Asriel bonding like siblings, Asriel talking about how they accidentally poisoned their father with buttercups before the fallen child tells to turn off the camera, Asriel being extremely uncomfortable with "the plan" but going through with it for the fallen child's sake, and finally the fallen child on their death bed from [[DrivenToSuicide self-inflicted buttercup poisoning]]. Alphys's (or Gaster's...?) notes add to the tears on the nearby console as it sounds like she's (he's) protecting Asgore.
-->'''Entry 4''' : I've been researching humans to see if I can find out any info about their SOULS. I ended up snooping around the castle... And found these weird tapes. I don't feel like ASGORE's watched them... [[AwfulTruth I don't think he should.]]
* If you kill Mettaton on a Neutral run, his almost [[PerpetualSmiler constant smile]] disappears and he concedes that you are indeed strong enough to defeat Asgore. He then tells you not to worry, that even though it looks like he's dying he's merely running out of batteries, and that [[BlatantLies Alphys can fix him]]. The saddest moment comes afterwards, where he tells you that although he might not have what it takes to be a star, he still got to perform for one human and thanks you with a sad smile on his face. When the game returns to the overworld, Mettaton's previously invincible rectangular body lies on its side, completely busted.
** To make it even worse, the dialogue for the employees at the resort change if you do this. Most of them are worried that Mettaton hasn't shown up, with some having no idea what to do without him.
* Alphys insisting that even if you had killed (or ''did'' kill) Mettaton, she could always rebuild him, becomes this once you know that she literally couldn't — she could only rebuild the shell that ''houses'' Mettaton, who is actually Napstablook's cousin and apparently an old friend of hers.
** Napstablook is the one to call at the end of the fight, complimenting their cousin on the show. Mettaton realizes this and tries to tell them to wait, saying "Wait, Bl..." before the shy ghost hangs up, struggling to keep his cousin's call anonymous when referring to them afterwards.
** After finding out Alphys was tricking you the whole time, it's easy to feel a sting of betrayal, but seeing her initial shock at the state Mettaton is in, and how worried she was that this ploy could have left Mettaton hurt or dead, is incredibly touching. You can't help feeling for her at that point.
* Also, the encounter with Mettaton NEO on a No Mercy run. Mettaton has to know perfectly well that he's no match for you, and if you've played the normal route you know that the power consumption for that form is so high that he couldn't survive a serious fight anyway. But he fights you anyway and pretends to be strong to try and bluff you into faltering, because as he says, there are people he wants to protect.

* In the True Lab, one of the Amalgamations — the one who hides in the form of a fridge — can be identified as the Snowdrake enemy's mother, at least as the primary consciousness. It can barely make an effort to attack you. Joking with it causes her to remember a part of herself, and should you 'Laugh' at the joke you told afterwards, you get this bit of dialogue.
-->''You laugh, and [[LaughingMad keep laughing. It's SO funny, you can't stop. Tears run down your face]]. ... what? You didn't do that?''
-->'''''It's so cold.'''''
-->'''''sn...o...wy...'''''
** When you first see her "snowy" mumblings, you may assume that she's talking about her home, Snowdin. However, speaking to a green Snowdrake on Snowdin road reveals that he and his friends live in the forest and eat the lunches their parents bring them, but mentions that they share their lunches with "''Snowy''" since his parents aren't around. In the midst of losing her mind to the sixteen other monsters, she still has enough consciousness to remember her son without having to be reminded of him, unlike the other amalgamates.
** The Snowdrake amalgamate also has their own [[https://www.youtube.com/watch?v=K-EHmQHUwB8 unique battle music]], which is a broken version of the Snowdin Road theme that's been sporadically slowed down and sped up in random places. It fits the monster very well.
** The resulting text from attempting to laugh is an indication that you aren't in full control of the human's actions at that point as they refuse to laugh. They're so sympathetic for the poor amalgamation that they refuse to do anything that might hut their feelings.
* Another one of the Amalgamations, Lemon Bread, becomes this if you buy the 'Mystery Key' from Catty and Bratty and enter Napstablook's cousin's house. Its primary consciousness is Shyren's sister, who had "fallen down" and contributed to Shyren's timid personality. When it speaks, the words fill up the screen in [[VoiceOfTheLegion many separate text boxes]], saying things like "Welcome to my special hell" and [[ArcWords "But nobody came"]]. It can hardly move, and you spare it by singing Shyren's song, reminding her of her sister.
* Rounding out the Amalgamates is Endogeny. If you're at all a dog person, this one's going to ''hurt.'' The only way to end the encounter is to try to comfort and play with the bounding, blob-like dog monster. The fact that ending the encounter plays a slower version of the cheerful Dogsong, proving that there's still a dollop of delightful doggo in Endogeny, makes it hurt even more. What's more, the somewhat off-kilter tempo of Dogsong, which ordinarily lends it a goofy, jovial tone, makes it actually sound a little sad when slowed down — it ends up emphasizing that this big, weird, blobby dog is most likely in constant pain, but smiling through it all.

* It's hard not to feel bad about Asgore once you learn everything that happened to him. He lost his two children in the same night and on a grief-driven fit of anger declared war on humanity and that he'd use their souls to break the barrier and kill them all... then he calms down and finds out he actually doesn't have the heart to bring his plans to come to fruition, and Toriel leaves him. He can't even back out of his plan because it's the only thing that keeps his people hopeful that one day their torment will end, but when you get him close to death, he accepts it, even begging you to do what you need to do.
-->'''Asgore''': I just wanted everyone to have hope... But...\\
'''Asgore''': I cannot take this any longer.\\
'''Asgore''': I just want to see my wife.\\
'''Asgore''': I just want to see my child.

* The fact that Asgore has left all of his family's items exactly as they were, despite the fact that there's no longer anyone around to use them, is possibly one of the saddest details of the game. There's still a reading chair by the fireplace, three extra chairs at the table (two of them child-sized), clothes and toys and neatly-made beds in the children's bedroom... and it's all been left untouched for years.

--->'''Toriel:''' Now I see who I was protecting by keeping you here. Not you… But them!!! Ha… ha…

** To expand upon this, killing Papyrus can be a heartrending introduction to the full game's path of No Mercy. Instead of fighting, he offers to become friends, reasoning that you are simply alone. You kill him with one shot. After that… he still believes in you. His final words are his telling you he knows you can be good if you try, before finally turning to dust.

*** If you kill both of them, the bear at the tree will talk about the couple's Christmas tradition. One of them would give the other a bone and the other would act like it's the first gift they've ever received even though they get it every year. Papyrus would then come and demand his bone back. Although it's a bit funny to think about the implication of where their yearly Christmas bones come from, it quickly goes back to being sad when he then wonders where the two are…

** Even the first time around, his comments about his father are this in a "Hahaha— ''[[CrossesTheLineTwice oooooh]]''…" sort of way.

* Despite being a silly bonus battle for the UsefulNotes/NintendoSwitch version, the Mad Mew Mew battle almost ends on a sad note.

IT WAS ME!!! ME!!! ME!!!!"
** However, as the fight goes on, it doesn't work, and the happy epiphany she had before sounds like a cruel twist.

** She loves to sing, but refrains from doing so because she isn't very good at it (her description outright calls her 'tone-deaf'). She also hides herself in a corner due to her shame over her 'scary' face, and only turns around to give you a nervous smile once you hum to her. Her sister has "fallen down" and was injected with Determination, causing her to meld with an Aaron and a Moldbygg. On top of all that, she's apparently started taking singing lessons… only to potentially be killed by you.

-->(''mimicking Toriel'') "Where oh where could that child be…? I've been looking all over for them…" (''in Flowey's shaky, crazed voice'') ...Hee hee hee. THAT'S not true. [[ReplacementGoldfish She'll find another kid, and instantly forget about you. You'll NEVER see her again.]]

…what did you do to him? What did you '''[[SuddenlyShouting DO TO HIM?]]'''\\

* Everything about Undyne is even worse if you're going for a No Mercy run. She takes an attack meant for the Monster Kid, and is mortally wounded… but her HeroicWillpower and desire to protect her friends and the rest of the world from you brings her back as Undyne the Undying. The song "Battle Against a True Hero" plays throughout the fight, conveying the feeling of hope. Although she's much more difficult to beat in a No Mercy run, it isn't impossible to kill her, and you will probably feel bad for doing so:

-->'''Entry 4''' : I've been researching humans to see if I can find out any info about their SOULS. I ended up snooping around the castle... And found these weird tapes. I don't feel like ASGORE's watched them… [[AwfulTruth I don't think he should.]]

* So Sorry's self-deprecation and death can be depressing. The RealitySubtext is even sadder: the character managed to get into the game because the owner of the character bought a $1,000 Kickstarter goal because he wanted to support Toby's game. Toby arranged that So Sorry be a secret character because Toby wanted to avoid controversy with the character… but, once Undertale's popularity exploded, his appearance became wide open. A lot of controversy happened because of the "furry fetish" character being in the game to the point of rumours forming that So Sorry can be killed without gaining EXP or ruining a Pacifist run. Add how the owner actually has depression and was bullied in his life, and…

** Oh, but it gets worse. If you kill Muffet, you know what you get? Exactly the amount of Gold you paid her during the fight (which can easily be zero). Muffet was telling the truth all along. She really did need that money…

** As you wander through the house in the end of a Neutral run, you begin to encounter monsters. They begin to tell you about how long ago, a human fell down and was adopted by the king and queen, and raised as their own alongside their real son. One day, the human child fell sick and died, their last request being to see the yellow flowers in their village again. The monster child absorbed their soul and took them back… only to be attacked by the humans in the village. He refused to fight back, and walked back home, still holding his sibling, and died as soon as he got to the throne room. The king, in his wild grief, declared war on humans and would destroy the barrier, murdering any human that came through. The monsters then describe how Asgore has given them hope again, and with the fact that a human is passing through the Underground, it won't be long before they're free again.

** In an odd way, the No Mercy version of this trip also qualifies. Flowey himself actually opens up to you directly about his experiences with turning into a flower and how distraught he was that he couldn't feel affection for Asgore, or anyone. His desire for love caused him to be DrivenToSuicide, in which he learned how to [[SaveScumming SAVE]]. At first, he used it for good, then [[VictoryIsBoring got bored with the world never changing,]] so he decided to kill everyone. But even that got boring to him until he met the protagonist, who was unpredictable enough to keep things interesting. At this point, he compliments you for being the only one that understands him, for sharing his merciless "[[SocialDarwinist kill or be killed]]" philosophy… [[BeCarefulWhatYouWishFor until he realizes]] that meant [[ChronicBackstabbingDisorder he too wasn't safe from you.]] It says a lot that the only person he could relate to was an OmnicidalManiac, and hearing his backstory straight from his own mouth is depressing in a distinct way from only hearing it second-hand in the other paths.

* The fact that Asgore has left all of his family's items exactly as they were, despite the fact that there's no longer anyone around to use them, is possibly one of the saddest details of the game. There's still a reading chair by the fireplace, three extra chairs at the table (two of them child-sized), clothes and toys and neatly-made beds in the children's bedroom… and it's all been left untouched for years.
* When Asgore first turns around to see you in a Neutral/Pacifist run, he is shocked at the sight of you and backs away for a moment. While it is possible that he is frightened at the last human appearing and the notion of having to make good on his declaration of war, some fans believe that like Flowey does, he might have momentarily mistaken you for his dead human child, Chara. He does admit in one ending to being reminded of Chara when he looks in your eyes, so perhaps he can't bring himself to look at you in the ensuing fight for more reasons than shame…

** Sans's attacks are beefed up versions of Papyrus' attacks — not a surprise, given their relationship. What is saddening is what can be extrapolated from them: the game states that a monster's thoughts can affect the form of their magic attacks. Check out the first proper attack of the battle — it's Papyrus' small bone rush attack, but paired with taller bones. We already know Papyrus' small bone rush shows up in his battle when he's thinking about his brother, which by extension means that the ''first'' thing that the boss is thinking about here is his brother and himself. The next attack after that is a sped-up version of Papyrus' tall light-blue bone/short white bone attack. Some fans have taken to calling the light blue attacks that can be avoided by non-movement 'ghost' attacks, which means that now Sans is thinking about Papyrus and himself again… except this time the tall bone is a 'ghost.' No wonder this battle is all TranquilFury and VideoGameCrueltyPunishment.

* One more note on the fight, Sans at the midpoint will say that somewhere, inside the player character, is the "memory of someone who wanted to do the right thing"… and ''pleads'' for them to remember him and abandon this. He knows about the "anomaly" (IE ''you''), and he can see Chara/The Fallen Child in front of him. He's not talking about ''either'' of you. ''[[IKnowYoureInThereSomewhereFight He's calling out to]] '''[[IKnowYoureInThereSomewhereFight Frisk]]'''.''

** Even the [[LastSecondChance last-second stop]] of No Mercy is heart-wrenching to say the least. You try to avoid killing Mettaton NEO, and in his last moments, he realizes you were motivated either by fear of monsters or simply didn't have enough hatred to be utterly evil. This one good-ish action results in Dr. Alphys surviving[[note]]By way of evacuating herself and several other survivors of the massacre to the True Lab, which meant they had to learn the AwfulTruth about the Amalgamates and Alphys' [[PlayingWithSyringes unethical experiments with Determination]].[[/note]] to become the new Queen… and she's in a complete HeroicBSOD, cursing her cowardice for not killing you when she had the chance and mourning her friends. It's made even worse in how she opens the call to the player by simply and coldly [[WhatTheHellPlayer stating that she hates them]].

* The fight with Asgore in the Neutral path. He starts by offering you tea, with a sad smile and saying it was nice to meet you. Then he averts his gaze and [[InterfaceScrew destroys the Mercy option so that you cannot spare him]]. Throughout the fight, [[HiddenEyes he refuses to make eye contact with you]]. However, you can still talk to him, and he will react to it, ultimately lowering his attack and defense, which shows that he actually doesn't want to harm you, but feels that there's no other way. If you bring Toriel's pie all the way to this fight and use it, the smell will remind him of Toriel, further reducing his attack and defense. The theme music that plays during the fight, "ASGORE", combines powerful orchestral segments with parts that sound melancholic and desperate, adding to the tragic atmosphere of the scene. And when you finally defeat Asgore, the Mercy command gets rebuilt, and choosing it makes Asgore talk about how you could all be happy together, giving a glimmer of hope… Which is immediately and mercilessly stomped on by Flowey, who attacks Asgore by surprise, either killing him and destroying his soul or destroying what's left of him if you don't choose mercy.
** Possibly even worse if this is another playthrough, and in the last one you killed Flowey (or if you spared him and got him to promise not to kill Asgore). He'll still give that same glimmer of hope… but he'll dismiss it, saying it's just impossible at this point. And then he'll force you to take his soul by [[DrivenToSuicide killing himself]]. [[YankTheDogsChain And]] ''[[YankTheDogsChain then]]'' [[YankTheDogsChain Flowey destroys his soul]].

* A lighter Fridge Sadness than most things on here, but several dialogue lines from Papyrus make it clear that he's not just overconfident, he's ''lonely''. He doesn't really have anyone other than Sans and Undyne (and you, later on) and the townspeople of Snowdin only vaguely know about him compared to his brother. The guy attempts to capture you and become popular but really he just wants [[IJustWantToHaveFriends friends.]]

** One bit of FridgeHorror that makes her neutral death worse: Her body melts throughout her final moments, meaning she's generating Determination just as she did in the No Mercy run. The difference between the two? Since you haven't gone completely Genocidal, there's still some doubt in her heart as to whether or not you truly deserve to die — you could have killed out of naiveté or self-defense and could still be a good person at heart. Considering that, on a Pacifist Run, deciding that "You're a wimpy loser with a big heart" is enough to get her to stop trying to kill you for good, and that even on a Pacifist Run, her pre-fight dialogue sounds like she's grasping for reasons to try and kill you, the idea that you're not 100% bad could very likely be enough to keep her from going full [[SuperMode Undyne the Undying.]] You may have dealt the last physical blow, but what ultimately killed her was her own internal conflict.

* Alphys' journal entries say that she doesn't want to finish building Mettaton's body because she's worried that if she does, he won't hang out with her anymore. It's pretty depressing by itself, but given that she hardly has any friends to start with…

** Remember at the end of the Ruins when Toriel said that Asgore will kill you if you venture out? This may create imagery of Asgore being some sort of malevolent all-powerful god-like entity. Yet as you travel through the Underground, many people speak of Asgore as a kind-hearted and fluffy guy who wants what's best for his people. When you finally reach him...it turns out "Asgore will kill you" and "Asgore is a NiceGuy" are ''both correct'', in the most gutwrenching way possible.
