History Characters / UndertaleSpoilerCharacters

* NiceHat: They wore the Cowboy Hat.

* StrangeSyntaxSpeaker: In the Japanese localization of {{VideoGame/Deltarune}}, you begin the game with a CharacterCustomization segment narrated in a bizarre combination of kanji and ''katakana'' in place of the usual hiragana. Katakana is usually reserved for loanwords, not basic sentence structure.

* Hope Spot: Possibly implied, There is a message in The Core that the cyan soul may have made it farther then some think. The message reads"(I cannot fight.) (I cannot think.)(But with patience I will make my way through.".

* TriumphantReprise: After reaching all of their hearts by calling for help, "Your Best Nightmare" changes from a terrifying to a joyous remix of "Your Best Friend".

* {{Leitmotif}}: A different remix of "Your Best Friend" for each of them plays when they are fought during the confrontation with Photoshop Flowey. Cyan's and Orange's versions are higher-pitched than the original, Purple's and Yellow's versions are lower-pitched, Blue's uses a whistle instead of chiptune, and Green's uses a piano.

* WordsCanBreakMyBones: During their attack phase, they send out negative words like "HATRED", "RUIN", "MURDERER", "DESPAIR", "TERROR", and "DESTROY". Calling for help changes them into positive words like "LOVE", "FREEDOM", "RELIEF", "MERCY", and "CREATE".

[[caption-width-right:136:Keep on persevering.]]

* BadassBeard: Although it's not known if they actually had one, the description of the Cowboy Hat says that it "makes you want to grow a beard."

* LuckilyMyShieldWillProtectMe: The green SOUL mode allows the player to block bullets coming from four directions, thereby implying that the green SOUL used their frying pan as a shield, rather than [[FryingPanOfDoom to beat people over the head with.]]

* AmbiguouslyEvil: The Old Tutu is described as "dusty" (in a world full of monsters, which turn to dust as they die) and the Ballet Shoes make the player feel "incredibly dangerous" after putting them on. Thus, it's implied that they killed at least one monster. However, it's not known if they did this out of maliciousness or simply self-preservation, since the monsters were also trying to kill ''them''.

* AmbiguouslyEvil: Their tutu is described as "dusty" (in a world full of monsters, which turn to dust as they die) and their ballet shoes make the player feel "incredibly dangerous" after putting them on.
* DanceBattler: Implied. The blue SOUL was wearing a tutu and ballet shoes, with the shoes being the weapons.

* BodyMotifs: Hands. Their weapon is the Tough Glove, the Ball Game describes them rushing "''fists''-first through all obstacles," their attacks consists of multiple hands, and their healing bullets are shaped like hands making the thumbs-up gesture.

* ChefOfIron: Implied of the green SOUL, who used a frying pan as a weapon and wore an apron.

* DanceBattler: Implied. The blue SOUL was wearing a tutu and ballet shoes, with the shoes being the weapons.
* DeliberatelyCuteChild: The Faded Ribbon, which belonged to the cyan SOUL, adds +5 defense and has the flavor text "If you're cuter, monsters won't hit you as hard."

* FryingPanOfDoom: The green SOUL's weapon is a burnt frying pan.

* HotBlooded: The orange SOUL, judging by their associated trait, Bravery, and the flavor text in the Ball Game.
-->'''Ball Game, orange flag''': You are the kind of person who rushes fists-first through all obstacles.

* KnifeNut: The cyan SOUL used a toy knife, which can be found in the Ruins.

* NiceHat: The Cowboy Hat belonged to the yellow SOUL.
* PlayingWithFire: Getting past the green SOUL during Photoshop Flowey's fight requires dodging waves of flames tossed from three frying pans.

* PowerUpFood: When turned to Frisk's side, the green SOUL tosses healing bullets shaped like fried eggs.

* DoNotTauntCthulhu: Implied. Trying to enter "Gaster" as the Fallen Child's causes the game to boot back to the title screen. Many of the Gaster followers are extremely hesitant in divulging information about him, only giving the player bits and pieces of his backstory at a time before shutting themselves up. However, when one of the Gaster followers arrogantly talks more than he should, he gets erased on the spot.

** His Entry Number Seventeen report in particular is completely inaccessible outside of hacking the game, which is interesting because it is a crucial piece of ProductionForeshdowing for ''Deltarune''. Its talk of darkness and the "garbage noise" that Gaster talks over are recurring plot points in that game.

** The original version of ''Deltarune'''s website in [[https://web.archive.org/web/20160817183540/http://www.deltarune.com/ December 2015]], ''unnoticed by the entire player base back then'', was a pitch-black page with a hidden message in Wingdings:

* KarmaHoudini: No matter what bad thing you will do, the in-game characters will be the ones punished. Nothing bad happens to you.

* SentientPhlebotinum: As they're the souls of humans who double as a source of inmense power they naturally qualify. This saves you against Omega Flowey when you get them to help you.

* NoSell: They're completely unable to die[[note]]by normal means at least[[/note]]: trying to attack any of them just causes red text to quickly flash by, bragging about the attack being ineffective, instead of damage numbers, and the HP bar of the one you attacked extends beyond the dialog box afterwards. Fortunately, this means you can't ruin your Pacifist run by accidentally killing one. While Snowdrake's Mother ''does'' take damage from attacks normally, she's still effectively unkillable as her health regenerates at the start of each turn.[[note]]She ''can'' be killed if you hack your ATK to the maximum value, but she's worth no XP, as this clearly wasn't intended to be a possible outcome of the fight.[[/note]]

* RecurringExtra: Reaper Bird's Everyman, named "strangeman" in the game's files, has two suspicious appearances in ''Deltarune'' — as a cameo in two boss fights (the {{Superboss}}' carousel attack in Chapter 1 and Queen's social media attack in Chapter 2) and as graffiti in the Light World. Toby Fox referred to him both on Twitter and the artbook as [[SuspiciouslySpecificDenial "Just a good guy that shows up on occasion"]], as if suggesting some ''kind'' of importance…

* HeWhoFightsMonsters: It's pointed out by [[spoiler:Sans]] that the more you kill, the more emotionally distant you grow, in an ItGetsEasier manner. Considering that all monsters display FantasticRacism with a few rare exceptions and most of them are activaly try to kill you, it's not too weird to start killing in self defense and then just keep doing it.

* LackOfEmpathy: While you aren't forced to sympathise with the cast even in the Pacifist route, not getting attached to the characters is pretty much a requirment in the Genocide route as you have to kill all of them, oftenly in horrible ways, while most of them are standing before you as paragons of virtue.

*** Interestingly, on a Full Pacifist Route, the game does this to you again with Asgore, but in reverse. Asgore's boss fight plays the RPG trope straight, you ''have'' to fight and beat him within an inch of his life to Spare him, but by then you've played almost the entire length of the game having adapted to its new rules. You end up frustrating yourself trying to find a hidden (non-existant) trigger for a non-violent Mercy Condition just as you've done all game for every other monster. [[DoubleSubversion Wrong Wrong Genre Savvy?]]

** To Sans, thanks to his Gasterblasters and scientific interests, with this often extending to Papyrus via proxy. General consensus is that Sans knew Gaster, but the exact nature of their relationship is never adressed.

** Whether the Riverperson's warnings about "the man who speaks in hands" and/or "the man who came from the other world" refer to Gaster is questionable. He is the most likely candidate for both quotes, as his speach relies in [[PaintingTheMedium hand signals]] and he doesn't reside in the world of ''Undertale'', but there are issues with this. For the former, not every symbol Gaster uses is a hand. For the latter, well, Gaster isn't really ''from'' another world as far as we know, he's just not in this one.

* PaintingTheMedium: Initially it was necessary for players to make a quick fix to the game's save file to enable the content related to Gaster. After a number of patches and ports this content was made available by default and ''expanded''. The announcement of ''Deltarune'' was later made by an unknown entity who remarks they and the audience have been looking for each other for a while, and that they look foward to connect with them.

* MirrorSelf: Goner Kid and Monster Kid have their (assymetrical) horns on opposite sides. Interestingly enough, Goner Kid's horn side ''does'' match Monster Kid's horn side in ''VideoGame/{{Deltarune}}''...

* TheUnreveal: It's never explicitly stated which of Gaster's creations caused him to become scattered across space and time. Possible candidates are the CORE, the Determination Extractor[[note]]Alphys' Entry #5 states that she used blueprints to use the Determination Extractor, but never says that she built it.[[/note]] and the mysterious machine hidden in Sans' basement, but it's also possible that it was none of these and was something else entirely.

* VoiceGrunting: The oddest sounding variety of it in the game: a jumble of random text-to-speech programs speaking in gibberish, only heard in the hidden Entry #17. They're actually fragments of a text-to-speech message from Toby Fox asking players not to spoil the game's secrets. The "Version 1.01" patch replaced the message with a bunch of text-to-speech voices [[LaughingMad laughing, one after the other,]] which sounds pretty much the same when jumbled up.

** Gaster Follower 3 = DoubleSubverted, as the "normal" version of this character later appears in ''VideoGame/{{Deltarune}}''
* WhamLine: The followers all speak of Gaster in the past tense, and the snippets of his story you hear all imply that he's dead, gone, or {{Ret Gone}}d. That is, until you speak to follower #3, whose final line suggests something [[TheOmniscient much stranger]]:
--> "Well, I needn't gossip. After all, it's rude to talk about someone who's listening."

* TemptingFate: Gaster Follower 2 says they have nothing to fear from Gaster, since he has a piece of him. They vanish ''immediately'' after they're done talking.[[note]]Notably, his disappearance is accompanied by the same sound that plays when the "Mystery Man" vanishes. The sound was also used for Goner Clam Girl.[[/note]]

* ProductionForeshadowing: Mentions her neighbor Suzy. Then says we will meet Suzy soon in the Nintendo Switch port. Not too long after the port's release, Sus''[[SpellMyNameWithAnS ie]]'' debuts as a deuteragonist in ''VideoGame/{{Deltarune}}''.

* WhamLine: Appears suddenly at the end of the exchange with Clam Girl to deliver a foreboding message.

* WhamLine: His followers all speak of Gaster in the past tense, and the snippets of his story you hear all imply that he's dead, gone, or {{Ret Gone}}d. That is, until you speak to follower #3, whose final line suggests something [[TheOmniscient much stranger]]:
--> "Well, I needn't gossip. After all, it's rude to talk about someone who's listening."

* TemptingFate: Gaster Follower 2 says he has nothing to fear from Gaster, since he has a piece of him. He vanishes ''immediately'' after he's done talking.[[note]]Notably, his disappearance is accompanied by the same sound that plays when the "Mystery Man" vanishes. The sound was used [[/note]]

* ProductionForeshadowing: Mentions her neighbor Suzy. Then says we will meet Suzy soon in the Nintendo Switch port. Not too long after that port's release, Sus''[[SpellMyNameWithAnS ie]]'' debuts as a deuteragonist in ''VideoGame/{{Deltarune}}''.

'''Goner Clam Girl''': ... is fast approaching.[[note]]Notably, this text box is displayed on the upper half of the screen, rather than the bottom.[[/note]]

* AboveGoodAndEvil: Since the world of Undertale is fictional and you're not, you are essentially this. However, the game will attempt to tell you that you aren't, especially in the No Mercy route.

* GreaterScopeVillain: …Also in a meta sense. With the Narrator Chara theory gaining more and more supporters, the ''Undertale'' fandom in general has come to the consensus that it's not Chara's fault — [[WhatTheHellPlayer it's yours]] for making Frisk do the genocide route and causing the world's destruction. These days, you'll find much more Website/YouTube comments along the lines of "Chara is evil in a Genocide Run, ''[[YouBastard but so are you and/or you made Chara that way!]]''" than the latter. Heck, there's even [[https://www.youtube.com/watch?v=rDLKqxNE59E a YouTube video out there]] with the song [[Music/{{Voltaire}} "When You're Evil"]] regarding ''the player'', not Chara. Given that there's no WordOfGod on the issue currently though, it's all open to interpretation, much like many other aspects of ''Undertale''. This trope only applies if you're going for a No Mercy/Genocide run.

* WorldsStrongestMan: According to [[https://undertale.fandom.com/wiki/W._D._Gaster the wiki]], his datamined stats are [[NumberOfTheBeast 666666 [=HP=], 66666 [=ATK=] and 66666 [=DEF=]]]. Compare this to the stats of the second strongest enemy[[note]]9999 [=HP=], 8 [=ATK=], and 9999 [=DEF=] for Asriel's FinalBoss form.[[/note]] and you see they're all comparably paltry. [[SubvertedTrope However]], seeing as Gaster technically does not exist in the world of Undertale, he also ''isn't'' the strongest monster.

* CanonForeigner: Only appears in the Nintendo Switch version of ''Undertale''.
