History Characters / TSUnderswap

* AdaptationalJerkass: She insults you more frequently after her fight, but this is just due to the fact that she was frustrated that her bakery hasn't been doing well and two monsters[[note: Implied to be Mettacrit and Sir Scratchalot]] that helped her get her bakery successful in the first place had abandoned her.

A spider monster.

* HeroicMime: Zigzagged. We don't get to hear them directly respond to monsters talking to them, but they do provide all of the game's narration.
* HiddenEyes: Once you're firmly set on a Ruthless Run, Chara's sprite will change, causing their eyes to be covered in shadows (similar to [[VideoGame/{{Deltarune}} Kris]]).

* PlayerCharacter: Due to the nature of ''Underswap'', you control them instead of Frisk.
* RippleProofMemory: Similar to dying to Toriel in Undertale, they'll remember if they were killed by Asgore in his fight, but decides it's too complicated to explain to him.
* TrademarkFavoriteFood: Chocolate. They even have a chocolate bar with them when they fall into the Underground, which gives them an extra healing item right off the bat.

* BigDamnHeroes: He saves Chara from death when all the Temmies gang up on them at the end of Ruined Home.

* GetItOverWith: Harry's response to you pushing Larry to his death on the Ruthless route.

* FakingTheDead: [[spoiler:In the Ruthless route, he quickly swaps himself for a cardboard cutout of himself when you're about to kill him. Despite this, Chara and Papyrus still think he's dead.]]

* EmergingFromTheShadows: [[spoiler:Temmie's friends are introduced this way. [[ByTheLightsOfTheirEyes Their glowing eyes and teeth appear in the shadowed parts of the room]], one at a time, and then they slowly begin to close in on you. Strangely, even when they step into the light, [[SinisterSilhouettes they're still covered by shadows]]. Three of the new ones appear uncovered later in the game but the remaining three have not yet been seen out of the dark. Curiously, if Chara is on a Genocide Route, you can sometimes see a Temmie in their monster forms still covered in darkness if you backtrack on certain screens.]]

* StalkerWithoutACrush: Temmie is shown to be following Chara throughout the whole game, just like Flowey in ''Undertale''. However, rather than briefly being shown burrowing into the ground if you backtrack, they instead appear in other ways (such as hiding inside cracks in the walls and floating down rivers in their box). [[spoiler: In a Genocide Route, they can briefly appear at the edge of the screen if you backtrack in certain rooms, only to flee when Chara gets near. Three of them appear to watch Chara while they sleep if they rest at the abandoned inn in Starlight, only to be gone because Flowerly chased them off.]]

* OOCIsSeriousBusiness: Although the Pacifist and Neutral routes seem to portray him as not taking his life as a superhero seriously, the Genocide Route shows that Sans is willing to step up and become the hero the Starlight Isles needs, ranging from helping monsters evacuate with the use of his shortcuts to saving Harry and Larry from Chara when they try to provoke them. To get across how serious he is, Crossbones drops the banter, jokes, and gets straight to the point, which gets the duo to understand the gravity of the situation and they immediately comply.

* EmergingFromTheShadows: [[spoiler:Temmie's friends are introduced this way. [[ByTheLightsOfTheirEyes Their glowing eyes and teeth appear in the shadowed parts of the room]], one at a time, and then they slowly begin to close in on you. Strangely, even when they step into the light, [[SinisterSilhouettes they're still covered by shadows]]--whether this is how they normally look or if they're simply still hidden is not yet known.]]

* SevenDeadlySins: [[spoiler: As of the second update to the demo, the Temmies have updated designs and dialogue/personalities to match this theming. Their leader is dressed in a suit and believes they are better than their underlings and is the only reason anything gets done (Pride), one wears a red shirt and leather jacket and just wants to kill Chara ASAP on a Pacifist/Neutral Route and encourage Chara to embrace their rage and kill everyone in a Genocide Route (Wrath), one is constantly sleepy, always resting on a pillow and wears pajamas and a nightcap and suggests take a nap in Genocide Route (Sloth), the one dressed the same as the shopkeeper within the original ''Undertale'' tried to take Chara's soul for themselves with their elongated arms (Greed), one of the unrevealed Temmies have hearts for eyes (Lust?) and another has a huge jaw in their monster form and wonders what souls tastes like (Gluttony), and one other unrevealed Temmie who enjoys the quiet in a Genocide Route (Envy?).]]

* StalkerWithoutACrush: Temmie is shown to be following Chara throughout the whole game, just like Flowey in ''Undertale''. However, rather than briefly being shown burrowing into the ground if you backtrack, they instead appear in other ways (such as hiding inside cracks in the walls and floating down rivers in their box).

* FriendlyEnemy: To Crossbones. Their feud consists of Koffin-K trying to pull wins on Crossbones in whatever petty ways he can, and Crossbones being entirely amused by it and trouncing him, with no intent to actually hurt or kill on either side.

* ClarkKenting: No one seems to realise that Sans and Crossbones are the same skeleton, despite Crossbones' mask not hiding much, and him occasionally slipping into his regular voice.

* OOCIsSeriousBusiness: Although the Pacifist and Neutral routes seem to portray him as not taking his life as a superhero seriously, the Genocide Route shows that Sans is willing to step up and become the hero the Starlight Isles needs, ranging from helping monsters evacuate with the use of his shortcuts to saving Harry and Larry from Chara when they try to provoke them. To get across how serious he is, he drops the banter, jokes, and gets straight to the point, which immediately gets the duo to comply, now understanding the gravity of the situation.

* DarkAndTroubledPast: Implied. If you take a second nap after pushing Asgore on how to leave Ruined Home, Chara's inner monologue mentions that they feel terrified at the thought of returning to the Surface, though they [[AmnesiacHero can't remember why]].

A monster that claims to be a supervillain, who's arch-nemesis of local superhero Crossbones.

A monster who claims to be a supervillain.

* SevenDeadlySins: [[spoiler: As of the second update to the demo, the Temmies have updated designs and dialogue/personalities to match this theming. Their leader is dressed in a suit and believes they are better than their underlings and is the only reason anything gets done (Pride), one wears a red shirt and leather jacket and just wants to kill Chara ASAP (Wrath), one is constantly sleepy, always resting on a pillow and wears pajamas and a nightcap (Sloth), the one dressed the same as the shopkeeper within the original ''Undertale'' tried to take Chara's soul for themselves with their elongated arms (Greed), one of the unrevealed Temmies have hearts for eyes (Lust?) and another has a huge jaw in their monster form and wonders what souls tastes like (Gluttony), and the last unrevealed Temmie has multiple eyes (Envy?).]]

* CorruptTheCutie: Seems to be the case, [[GainingTheWillToKill influenced by LV]] [[spoiler:and [[DemonicPossession being under the control of the player]]]] in Genocide.

** [[spoiler:This [[AmbiguousSituation may]] be happening in Genocide as well. Chara's face becomes shadowed like Kris' when we are controlling them, and [[https://tsunderswapofficial.tumblr.com/post/178011527125/will-chara-speak-or-have-optional-dialogue this]] response on Tumblr indicates that the team sees the player as responsible for Genocide, not Frisk. Since we are now controlling Chara, they may also be controlled by the player in-universe for Genocide.]]

* HiddenEyes: Once you're firmly set on a Genocide Run, Chara's sprite will change, causing their eyes to be covered in shadows (similar to [[VideoGame/{{Deltarune}} Kris]]).

* HorrifyingTheHorror: [[spoiler:When Genocide Chara makes it clear that they have no desire for a partnership, all but the un-shadowed Temmie retreats, [[TooDumbToLive who doesn't think that Chara's that bad]]. Had it not been for Flowey popping up, they might have regretted those words.]]
* InLoveWithYourCarnage: [[spoiler: The Temmies are absolutely ''delighted'' by a Genocidal Chara and will offer them their assistance. Unfortunately for the Temmies, it becomes apparent that their help isn't wanted or needed...]]

* AdaptationalBadass: [[spoiler:In Genocide, Asgore puts up a much better fight in the TS!Underswap demo than either Toriel or Asgore did against the player character in ''Undertale'', despite both player characters being about the same LV. Especially impressive since he is physically older than his counterparts from passing his life-energy onto Asriel.]]
* AdaptationalHeroism: [[spoiler:Asgore makes a genuine effort to kill Chara and stop them from killing his people in Genocide, whereas both Toriel and Asgore in ''Undertale'''s Genocide were mowed down in one hit without realizing how dangerous the player character was until it was too late.]]

* BewareTheNiceOnes: Even though he's a warm, fatherly goat man, he'll still fight you near the end of Ruined Home to keep the other monsters from getting your SOUL. [[spoiler:He also won't hesitate to kill you on a Genocide run, with stronger attacks to boot.]]
* BigGood: In the demo. He is a leader to the Ruined Home monsters even without an official position, Temmie and the Mad Dummy are both afraid of messing with Chara more directly if he's around them and [[DirtyCoward resort to waiting until he's not around to help]], and he does everything in his power to [[spoiler:[[LetsGetDangerous stop Chara if you go Genocide]], being by far the most difficult challenge in the game thus far]].

* HeroicBSOD: [[spoiler: Asgore is just completely speechless and shocked if you abort a genocide run by sparing him. [[note]]You have to hug him after his final attack.[[/note]] He will just kneel on the ground in complete silence. If you leave and come back, he will lock himself in his home and refuse to talk to you.]]

* LastDitchMove: [[spoiler:In Genocide only. Just before he runs out of health, he will perform a final, super-difficult-to-dodge attack--first he performs a rapid series of jabs with his trident, then he slams it into the ground to create giant rings of fireballs.]]

* NightmareFace: [[spoiler:He makes a pretty terrifying face during his final attack on a Genocide run, as a reference to one of Toby Fox's original concepts.]]

* ReasonYouSuckSpeech: [[spoiler:If killed in a Genocide run, he tells Chara will be alone in their "special hell" when they're done killing everyone.]]

* WillfullyWeak: It's pretty obvious that Asgore is holding back when you fight him, since he doesn't really want to hurt you. [[spoiler:Should you decide to do Genocide, [[LetsGetDangerous he'll stop holding back]].]]

* AgentPeacock: He may be very flamboyant and campy, but Mettacrit is the last mini-boss of Ruined Home, meaning he's considerably more challenging than the previous ones. It's downplayed in a normal run since he's not really trying to kill you, but played straight on the Genocide Route where he tries holding you off so the other monsters can escape.

* FakingTheDead: You can "kill" Mettacrit, but it's blatantly obvious from what we know from the original game and what a show Mettacrit puts on as he does it that it's just an act. In a neutral run, he'll even tell you that ghosts are immune to your attacks, but in a genocide run, the journal will list him as dead even though he faded away rather than dusted, and you didn't gain any EXP from it, implying that Chara believes they really killed him.

* AdaptationalBadass: His ''Undertale'' counterpart is shown being easily knocked away by Toriel with a fireball, banks on getting [=SOULs=] to power himself up to god-like levels before he fights Frisk again, and dies without putting up a fight if you choose to kill him in Neutral or Genocide. In comparison, if [[BigGood Asgore]] is already dead, this Flowey can scare off the BigBadDuumvirate ''himself'' by threatening them with a fight - that's seven Temmies he's willing to take on with only Chara as potential backup - and in Genocide, he's the one who easily knocks away the attacking Temmie with a single friendliness pellet.
