History Undertale / TropesGToN

** On the Neutral (or imperfect Pacifist) path, [[spoiler:Flowey]] turns the fight into a ''real-time'' bullet hell, with the ACT and FIGHT buttons appearing at regular intervals.

** On the neutral path, after [[spoiler:Flowey kills the king]], the game window automatically closes. When reopened, the opening cutscene glitches out and then goes straight to his boss battle, where [[spoiler:Flowey]] even abuses savestates to try and mess with you.

** The track "Fallen Down" was one of Toby Fox's contributions to [[http://sleepytimejesse.bandcamp.com/album/i-miss-you-earthbound-2012 I Miss You]], an album of tracks made with VideoGame/EarthBound's soundfont back in 2011-2012.

* HellIsThatNoise:
** There's a very distinct and awful scratchy sound that plays whenever you interact with a Gaster follower immediately before they vanish into thin air, and that's not even getting into the hellish cacophonies used for any of the DummiedOut rooms.
** If you kill all monsters in an area, RandomEncounters still occur, but only display the words "But nobody came", and from there the music for the area is replaced with a demonically slowed down version of Flowey's theme.
** There are only two fully voiced lines in the entire game across all routes. The longer of these occurs [[spoiler:during a conversation with Flowey during the No Mercy run, where he mentions wiping out the world. Without appearing in the text box, a horrible voice says "that's a wonderful idea!"]] The other is [[spoiler:a robotic “OH YES” that plays when Mettaton premieres his EX form]]. Most players will find that two is ''plenty''.
** Flowey's EvilLaugh never fails to be creepy. [[spoiler:It gets ramped up to nightmare-inducing levels once he transforms into his SOUL-powered form. It even makes its way into the soundtrack! It gets even creepier if you complete a True Pacifist run after selling your soul in a Genocide run and choose to stay with Toriel.]]
** [[spoiler:The Fallen Child]] gets two really creepy themes. One is the menacing [[https://youtu.be/uGqvpMQQ48o "In My Way"]], which plays during two encounters with monsters that will not attack you and can be instantly spared… or instantly killed. And the other is a [[https://youtu.be/93q3irqZxxo warning drone]] noise that indicates [[VideoGameCrueltyPunishment you've finally met your match]] at the end of a Genocide run.
** An in-universe example: If you visit Napstablook, listen to one of their music tracks, keep it on when you leave, and go south, you'll encounter Aaron and Woshua. Their reaction is hilarious, and seeing the scene actually helps you get rid of Aaron quickly (and non-violently) if you run into him again.

* GameGourmet: This being a SpiritualAdaptation to ''VideoGame/{{Earthbound}}'', there is a plethora of different foods you can eat, all of which have {{Punny Name}}s and descriptions. Without spoiling anything, [[http://undertale.wikia.com/wiki/Category:Items#Consumables see for yourself!]][[invoked]]

* GenderNeutralWriting: The main character, Napstablook, Monster Kid, and [[spoiler:the Fallen Child]] are only ever referred to using gender-neutral pronouns.[[note]]It also makes translations to other languages outside English, Japanese, Korean, and Chinese next to impossible, since most languages don't have this.[[/note]]

* NeverTrustATrailer: Parodied.

* NeverTrustATrailer:

** ALL of the Underground during a Genocide Run, to the point that [[spoiler:Alphys takes all the survivors into hiding]].
** [[spoiler:The boss monsters when Flowey catches them in the GoldenEnding]] and again, all the monsters of the Underground when [[spoiler:Flowey absorbs their [=SOULs=].]]

** Several parts of the No Mercy route encounter with Papyrus are echoed by the one with Sans. For instance, [[spoiler:Papyrus tells the player that he believes anyone can be great if they try; at the end of the route, Sans paraphrases this as an ArmorPiercingQuestion, asking the player if they believe it.]] Additionally, throughout both conversations, the player keeps walking towards them without saying anything, while Papyrus and then Sans attempt to talk them down. And [[spoiler:like Papyrus, Sans eventually offers to spare you - though by that point he is ''not'' going to let you live if you accept.]]

** Asgore Dreemurr, which is pronounced ''Dreamer''. He's known for his dream of saving the monsters underground more than his person.

** You can't gain EXP by sparing enemies. You need to kill them if you want to increase your LV. (In the demo, you can spare injured monsters for EXP; this ability was removed in the full release, however, as it [[spoiler:[[GameplayAndStorySegregation contradicts certain events late in the story]]]].)

* MirroringFactions: The opening intro leads you to believe that monsters and humans are totally different and the monsters are painted as the evil ones. Should you spare monsters and talk to various [=NPCs=], you can see that they aren't really that much different from humans in terms of what they celebrate, what their favorite hobbies are, and so on, but very few character actually mention the similarities. [[spoiler:Should you get the GoldenEnding, the trope is further expanded upon where humans and monsters are able to coexist with each other peacefully and very easily since they're very much alike.]]

** On No Mercy, if you fall for [[spoiler:San's fake spare]], he'll insta-kill you and tell you to "geeettttttt dunked on!!!"... then tell you afterwards that if you're really friends, you "won't come back." [[MoodDissonance All while a sped-up version of "Dogsong" plays during the game over screen.]]

* MoralMyopia: To a degree; the ultimate goal of the monsters is to break out of the Underground, and thanks to the power of human [=SOULs=], [[PoweredByAForsakenChild killing you is the easiest way of accomplishing that]]. This leads to some moral issues when you consider that using force to stop them from doing this will get you criticized, even if you were in danger of being killed yourself, and you are always accused of doing this out of annoyance rather than self-defense regardless of the player's motivations for doing so. However, the number of monsters that attack you intentionally is rather low, and those that do are shown to be conflicted about it, as seen with Undyne ([[spoiler:who tries to look for a better reason to kill you before her fight]]) and Mettaton ([[spoiler:who is concerned Asgore will wipe out humanity if he gets a hold of your SOUL]]). The game seems to be a test of the player's patience, as Flowey mocks during a Pacifist Run, since he suggests that you might kill out of boredom or frustration after dying multiple times.

** [[spoiler:The Fallen Child]] gets two really creepy themes. One is the menacing [[https://youtu.be/uGqvpMQQ48o "In My Way"]], which plays during two encounters with monsters that will not attack you and can be instantly spared… or instantly killed. And the other is a [[https://youtu.be/93q3irqZxxo warning drone]] noise that indicates you've finally met your match at the end of a Genocide run.

* HeroicWillpower: In the True Pacifist final boss battle, [[spoiler:the captured monsters use their powers to protect Frisks's soul. They each give a RousingSpeech that the human can defeat Flowey]]. Undyne is also fighting back.

* HiddenDepths: ''Every'' major character has more to them than meets the eye. However, due to the game's extreme level of sensitivity to player choice, it's literally impossible to explore them all in a single run. In particular, going full genocide results in a very strong example of TheApocalypseBringsOutTheBestInPeople, exposing depths that would only be hinted at otherwise. On the flipside, just about ''everything'' about Flowey is kept hidden from the player until the end of a true pacifist run.

** If you chose to kill Undyne during a Non-Genocide run, she will continue attacking for a few rounds after her HP runs out, but her attacks will get progressively slower, while sad music begins to play in the background.

** The player character's name is actually [[spoiler:Frisk, and the character you named at the beginning is really the Fallen Child]] .

* InsurmountableWaistHighFence: To a certain extent. In New Home, you come across a long chain blocking the way downstairs to progress, requiring you to explore the house more to find the two keys to unlock it with. Why the Child doesn't simply crawl under it or jump over it and ignore it is never elaborated on, even on the KillEmAll path where they would likely much rather get past it and to the next battle as soon as possible.

* MultipleEndings: Now has [[MultipleEndings/Undertale its own page]].

* MultipleEndings: Three basic variants, though the phone call at the end of a Neutral run has several sub-variants of its own. None of these have official names.
** Neutral: Basically the default ending, you get this if you don't qualify for the other two. First, you fight Asgore. [[spoiler:Then, you can kill him or spare him — but if you spare him, Flowey kills him himself, and then shatters his SOUL either way so you can't use it to escape the barrier. Then he steals the human [=SOULs=] and goes OneWingedAngel to fight you as Photoshop Flowey — unless you've gotten this ending before, in which case he figures, why bother?]] Either way, you end up outside the barrier, somehow, and much later, you receive [[https://pcy.ulyssis.be/undertale/endings.pdf a phone call]] from Sans.
*** Toriel ending, sometimes "Neutral Pacifist": Don't kill Toriel, Papyrus, or Undyne, and don't kill more than 10 {{Mooks}}. Toriel takes over as queen, and makes a policy that humans who fall into the underground are to be treated as friends, not enemies. She also disbands the Royal Guard (except for Papyrus). Minor dialogue changes occur if you hung out with Undyne, killed anyone after hanging out with Undyne, killed Mettaton, or hung out with Alphys. If you spared Flowey and hung out with Alphys, he'll clarify here that to get the GoldenEnding, you have to "finish the date" by entering the True Lab. If you didn't kill any Mooks and spared Asgore and Flowey, you can just reload the save to accomplish this, but otherwise you'll have to start over.
*** "Exiled Queen": Don't kill Toriel, but do kill Papyrus, Undyne, or more than 10 Mooks. [[spoiler:Toriel tries to take over as queen, but is overthrown by monsters who hate humans due to your actions. If you didn't kill Undyne, she spearheads the revolution, otherwise Toriel realizes her policy is unwanted and leaves peacefully. If you killed Papyrus, Sans chews you out for it and tells you never to come back.]]
*** Undyne ending: Kill Toriel, but not Undyne. [[spoiler:Undyne takes over and plans to wage war against humanity. If you didn't kill Papyrus, she assigns him to "The Most Important Royal Position", which consists of standing around and looking cute. If you did kill Papyrus, Sans chews you out for it and tells you that things do not look good for you.]]
*** Mettaton ending: Kill Toriel and Undyne, but not Mettaton. [[spoiler:Mettaton takes over as king and makes the underground into his {{Egopolis}}. Sans and (if you didn't kill him) Papyrus are his agents, which Sans thinks is ridiculous but Papyrus thinks is awesome.]]
*** Papyrus ending: Kill Toriel, Undyne, and Mettaton, but not Papyrus. [[spoiler:Papyrus becomes king, by process of elimination. He seems to be doing pretty well by just telling everyone to work hard and making spaghetti for them, but it's implied that Sans is doing the real work.]]
*** [[DarkHorseVictory Annoying Dog ending]]: Kill Toriel, Papyrus, Undyne, and Mettaton, but absolutely nobody else. Somehow, a small white dog becomes the ruler of the Underground. It spends all its time sleeping on the throne and does absolutely nothing important. Somehow, this works out pretty well.
*** Anarchy ending, also known as the "No Mercy" Route: Kill Toriel, Papyrus, Undyne, Mettaton, and at least 1 Mook, but don't go full KillEmAll: [[spoiler:With the death of everyone important, the Underground descends into despair. Sans laments that this is what happens when people like him take it easy. If you killed more than 20 enemies, he also chews you out for that and tells you to go to hell.]]
*** Alphys ending: Abort a Genocide run by not depopulating the Hotlands + CORE area[[note]]The actual coded requirement is to kill Toriel, Papyrus, Undyne, and Mettaton, and have a "murder level" of at least 12 but below 16. The [[https://www.reddit.com/r/Underminers/comments/3r1hcc/using_undertaleini_to_activate_flags_specifically/cwl1n4g?context=3 murder level calculation]] makes it clear that this is the only way to do that; specifically, murder level 12 is reached by killing Undyne the Undying, at which point the only ways back onto Neutral for this ending are to spare the Royal Guards 01 and 02, spare Muffet, or fail to exhaust the random encounters in Hotland and the CORE. In all cases, you will face Mettaton NEO, who cannot be spared.[[/note]]: [[spoiler:Sans hands the phone to Alphys, who declares she has to do ''something'' about your murder rampage, and for what she does (and a lack of better candidates), the monsters elect her as their new leader. She only called to tell you she hates you for what she did, and laments that she should have killed you when she had the chance.]]
*** "Dirty hacker", or "error handler": This ending [[DummiedOut can't actually be reached]]; every possible game state will somehow lead to another one. If you ''could'' reach it, Sans would admit that he has no clue how you did it, and suggest telling Toby how you got there — but then admit you're probably only seeing it because you hacked the game.
** GoldenEnding, mostly known as "True Pacifist", though the naming screen EasterEgg indicates it was probably supposed to be something like "mercy run". After getting a Neutral ending and sparing Flowey, he'll give you a hint as to how to get here — kill 0 enemies, and hang out with Papyrus, Undyne, and Alphys. You can't actually hang out with Alphys unless you've gotten a Neutral ending, which ensures that you can't get this ending first, but if you killed 0 enemies and gave Undyne the water, you won't have to reset, just reload. You go through the True Lab and learn of Alphys's failed experiments, and how Flowey came to be. Then, when you face Asgore, Toriel interrupts the fight and tells the two of you that there will be no killing today. All of your friends gather… putting them in place for the final boss to take advantage of them. [[spoiler:Flowey appears to steal all of their [=SOULs=]. With six human [=SOULs=], and the SOUL of every monster in the Underground making up for the seventh, Flowey can finally take on his true form — Asriel Dreemurr. After an intense fight, you save all of your friends' souls, allow Asriel to make peace with himself and you, break the barrier on the underground, and live a life with all your friends, and every monster on the surface in harmony with humans. You either live with Toriel taking care of you, or remain in contact with her as friends.]] Arguably the true ending, as it's the only one with a credits sequence.
** The "Genocide" or "No Mercy" route[[note]]Not to be confused with the Anarchy/No Mercy Neutral path above[[/note]], occasionally called "[[LevelGrinding Max LV]]" or some variant on "a bad time", and the naming screen EasterEgg indicates it was probably meant to be called something like a "murder run". In each of the four areas (Ruins, Snowdin, Waterfall, Hotland+Core), kill RandomEncounters until the AntiGrinding kicks in, making sure not to miss any UniqueEnemy, then kill the boss. [[spoiler:The tone of the game changes wildly, and every boss except Undyne goes down in one hit. Save points outside the Ruins just read "X left", and then "Determination" once you've killed them all. The monster history sequence in New Home is replaced with Flowey explaining his personal backstory. He caps it off by saying he appreciates you because like him, you're the kind of person who'd just kill anyone who got in your way, including him. Then he realizes, OhCrap, ''you're probably going to kill him''. Sans's judgement in the Last Corridor is replaced with an incredibly difficult boss fight, and when you finally overcome him, you kill Asgore in one hit and brutally murder Flowey. Then the Fallen Child appears. They explain that your actions convinced them that their UnexplainedRecovery was a chance for them to kill the enemy and grow strong, and now that you've killed all enemies, it's time to destroy this world and move on to the next. (This means to move on to the next video game. After all, you're done with this one, right?) You don't get a choice in the matter.]] After getting this ending the first time, the entire game is replaced with a blank screen. [[spoiler:If you wait 10 minutes, the Fallen offers to restore the world, if you give them your SOUL. This lets you play the game again, but permanently alters both the GoldenEnding and the No Mercy ending. If you Kill everyone again, the Fallen Child is baffled that you'd do so after selling your SOUL to restore the world, since it was doing this once that necessitated that exchange in the first place. In fact, they're so baffled that they restore the world for free and tell you to take a different path next time. If you ''do'' take a different path and go for the GoldenEnding, the very last scene gets a {{Stinger}} reminding you that the Fallen is the one in control now, and implying that they're going to Kill them without you.]]

* MythPrologue: The game opens with the tale of how the war between humans and monsters started, and how the monsters were sealed underground. It then tells the myth of how those who climb Mt. Ebbot never return.

*** Alphys ending: Abort a KillEmAll run by not depopulating the Hotlands + CORE area[[note]]The actual coded requirement is to kill Toriel, Papyrus, Undyne, and Mettaton, and have a "murder level" of at least 12 but below 16. The [[https://www.reddit.com/r/Underminers/comments/3r1hcc/using_undertaleini_to_activate_flags_specifically/cwl1n4g?context=3 murder level calculation]] makes it clear that this is the only way to do that; specifically, murder level 12 is reached by killing Undyne the Undying, at which point the only ways back onto Neutral for this ending are to spare the Royal Guards 01 and 02, spare Muffet, or fail to exhaust the random encounters in Hotland and the CORE.

She only called to tell you she hates you for what she did, and laments that she should have killed you when she had the chance.]]

** KillEmAll ending, commonly called "Genocide" or "No Mercy"[[note]]Not to be confused with the Anarchy/No Mercy Neutral path above[[/note]], occasionally called "[[LevelGrinding Max LV]]" or some variant on "a bad time", and the naming screen EasterEgg indicates it was probably meant to be called something like a "murder run". In each of the four areas (Ruins, Snowdin, Waterfall, Hotland+Core), kill RandomEncounters until the AntiGrinding kicks in, making sure not to miss any UniqueEnemy, then kill the boss.

If you ''do'' take a different path and go for the GoldenEnding, the very last scene gets a {{Stinger}} reminding you that the Fallen is the one in control now, and implying that they're going to KillEmAll without you.]]

* KillEmAll:
** The monsters you meet in random encounters aren't infinite. If you keep killing them, even the monster [=NPCs=] will disappear. [[spoiler:[[EarnYourBadEnding Doing this for all areas, though incredibly tedious,]] will give you a vastly different (and [[DownerEnding darker]]) ending.]]
** If there are leftover monsters remaining, they will flee for their very lives.

* GreenGators: Bratty is a bluish green alligator monster.

* HumansKillWantonly: There are many monsters trying to kill you. Maybe they want your soul [[UtopiaJustifiesTheMeans so Asgore can break the barrier and free the monsters]]. Maybe they want to prevent Asgore from getting your soul and destroying humanity with it. Maybe they think [[PoorCommunicationKills that you're a horrible monster]] just because you couldn't afford to spend money on that overpriced bake sale. Or maybe they actually don't want to kill you, but are simply unaware that their actions risk hurting you. You, on the other hand? You kill because you ''can''.

** If you replay the game on [[NewGamePlus Hard Mode]] and kill [[spoiler:Toriel]], it gets stopped after the battle and the Annoying Dog shows up, saying that's where Hard Mode ends. [[spoiler:Toriel then casually brushes off death to bake another pie, as if the whole fight never happened.]]

* NotQuiteBacktoNormal: [[spoiler:A True Reset will erase every single event from every characters' memories and the game will be as if it was just installed. However, if the player completes the Genocide route, Chara will take over. A True Reset will never truly remove their presence from the game.]]
