* BigDamnHeroes:
** Asgore accidentally saves you from Temmie when they try and kill you, forced to flee when they hear him coming, and [[spoiler:when seven of them try to gang up on you, ''Flowey'' pops up to defuse the tension by threatening to call Asgore on them. In Ruthless, the Temmie that didn't flee tries to kill both Chara and Flowey, only for the flower to effortlessly one-shot them with a pellet and knock them away.]] [[spoiler: Flowey once again seems to do this when in the hotel attic on a Ruthless route, popping up just in time before some shadowy creatures could attack Chara.]]
** If you attempt to kill Muffet or Koffin-K in a neutral run, Crossbones will save them as soon as you try to finish them off.

* SeasonalBaggage: Undertale's four main areas seem to be themed around the four seasons, the Ruins fitting for Autumn, Snowdin being Winter, Waterfall being Spring, and Hotland being Summer. Team Switched shifted the seasons assigned to each area, so "the Ruins" swapped seasons with "Waterfall" and "Snowdin" swapped seasons with "Hotland". Ruined Home (the equivalent to the Ruins) is now Spring with golden flowers and lush greenery growing everywhere ([[FridgeBrilliance likely because]] [[CaringGardener Asgore]] is now the caretaker of Ruined Home), Starlight Isles (the replacement of Snowdin) is now Summer with {{pirate}} themes to bring to mind the tropics, Crystal Springs (the equivalent of Waterfall) will be Autumn, and Boreal Bluffs (the replacement of Hotland) will be Winter.

* AmbiguouslyEvil: Downplayed with [[spoiler:Flowey]] in the demo because his motives in the game have yet to be revealed. It's made pretty clear he's [[spoiler:still not a sweet and innocent flower even in this world, between him hinting that Chara will need to kill to survive, Temmie thinking he's put Chara up to their actions in Ruthless and admitting to envying him as a rival in that ending, and in Neutral him not perturbed in the slightest if Chara betrayal-kills Asgore, still saying that Chara is like him and admitting to being no better than the Temmies sometimes. Still, he chases the Temmies off before they can gang up on Chara when he didn't need to, makes no move to attack Chara and take their SOUL himself, and instead is set up as an ally to them and an enemy to the Temmies for the full game. Since his ultimate goals are unknown, it's not clear if Flowey is biding his time playing a longer con on Chara than his Undertale counterpart pulled on Frisk, or if he will be a sort of [[AntiHero morally lax ally]] leaving the active villainy up to the Temmies.]]

** [[spoiler:Asgore is still the one who declared war on humanity, with the difference being that Toriel did not leave him after this even though she disagreed. The reason he's in Ruined Home now is because she exiled him there for deciding he no longer wanted to through with the plan.]]

* {{foreshadowing}}:

** [[spoiler:Asgore is still the one who declared war on humanity, with the difference being that Toriel did not leave him after this even though she disagreed. The reason he's in Ruined Home now is because she exiled him there for being a coward after he gave up on the plan.]]

* BigShutUp: [[spoiler: The conversation with Papyrus after fighting Sans on a Ruthless route can result in Chara shouting one of these.]]

* DiesDifferentlyInAdaptation: The Justice SOUL and implicitly the other fallen humans. Chara finds the Justice SOUL's Cowboy Hat and Toy Gun in Ruined Home instead of the Patience SOUL's items, when in ''Undertale'' the Justice SOUL's items were found by Bratty and Catty in the dump at Waterfall. Obviously Justice didn't make it that far in their journey across the Underground in this world.

** [[spoiler:In the Ruthless route, Sans/Crossbones quickly swaps himself out for a cardboard cutout when you're about to land the last attack on him. Despite this, Papyrus still thinks he's dead, and Chara either thinks so as well, or just believes that his Crossbones persona is no more]].

* BigDamnHeroes: Asgore accidentally saves you from Temmie when they try and kill you, forced to flee when they hear him coming, and [[spoiler:when seven of them try to gang up on you, ''Flowey'' pops up to defuse the tension by threatening to call Asgore on them. In Ruthless, the Temmie that didn't flee tries to kill both Chara and Flowey, only for the flower to effortlessly one-shot them with a pellet and knock them away.]]

* KickTheDog: [[spoiler:Checking the note by Asgore's toilet while on a Ruthless run has Chara call it idiotic drivel.]]

* HelloInsertNameHere: We still get the opportunity to name Chara despite the role swap, and this time around it's a straight example because now they're unambiguously our player character. Like ''Undertale'', the game has some special responses to certain names. [[https://www.reddit.com/r/tsunderswap/comments/kjazkx/spoilers_naming_easter_eggs/ Here's a list.]]

* AllWebbedUp: In the Compassion and Neutral routes, Muffet captures Chara, Crossbones, and Papyrus, having the former stuck in a large web where they can't reach their armor item at first, and the latter two tied up and dangling upside-down. [[spoiler:In the Ruthless route, she instead has Lesser Dog and Greater Dog tied up, and you fight her in the forest instead of her shop, where the FIGHT button is made inaccessible from her trapping Chara in webs during the battle, requring you to use the "struggle" act to free it.]]

* NonstandardGameOver: [[spoiler:Dying to Crossbones in Ruthless will have the usual Game Over music be replaced with something sillier, while a screenshot of the moment you died is shown as a photograph, with Crossbones commenting on it.

* AdaptationalBadass: In Ruthless, Asgore puts up a much better fight in the TS!Underswap demo than either Toriel or Asgore did against the player character in Undertale's Genocide, 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.

* AllWebbedUp: In the Compassion and Neutral routes, Muffet captures Chara, Crossbones, and Papyrus, having the former stuck in a large web where they can't reach their armor item at first, and the latter two tied up and dangling upside-down. [[spoiler:In the Ruthless route, she instead has Lesser Dog and Greater Dog tied up, and you fight her in the forest instead of her shop, where the FIGHT button is inaccessible at first.]]

** The Demo V2 has a setting that allows you to adjust the difficulty, affecting how much damage you'll take in battles in case you're having too much difficulty dodging attacks.

* 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 Ruthless 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.

* FunetikAksent: As shown by one of the naming EasterEggs below, Alphys seems to have a French or German accent that she didn't have in ''Undertale''. [[spoiler:It's implied by her dialogue on the naming screen if you try to use her name that it's just an act, and confirmed in the Ruthless route where she drops it altogether]].

* ImStandingRightHere: [[spoiler: After leaving Starlight Isles, Chara comes across three Temmie on the bridge, talking about what to do with them. When they finally notice Chara slowly approaching them, they immediately stop talking and let them pass by.]]

* BreakingTheFourthWall: Papyrus and Sans at the end of the demo's post-credits sequence, where Papyrus lampshades that people would've expected [[spoiler:to encounter him instead of Sans]] (referencing how vanilla Underswap has Papyrus [[spoiler:replace Sans in meeting the human first]]) and assuring fans that waiting for the full game to come out will be worth it.

* FunetikAksent: As shown by one of the naming EasterEggs below, Alphys seems to have a French or German accent that she didn't have in ''Undertale'' (although she seems to drop it when she says you can't use her name, implying that it might be an act).

** When fighting Asgore on a Ruthless run, [[spoiler: his final attack is taken from one of Toby Fox's earlier ideas as seen in the artbook, as is the terrifying face he makes during it]].
* NightmareFace: Temmie follows in Flowey's footsteps by busting out a few of these, complete with [[EvilLaugh evil cackling]].

* RecurringBoss: Downplayed with the Mad Dummy. We haven't actually fought them yet (unless you count the tutorial), but they reappear to chase Chara through Ruined Home and will likely show up for another fight in the full game since they haven't settled the score by the time Chara leaves Ruined Home.

* StalkerWithoutACrush: The Temmies stalk Chara around the Underground, intending to kill them and steal their SOUL. Unlike with Flowey in vanilla ''Undertale'', this isn't limited to catching them moving out of view upon backtracking back to the entrance of a room and they'll sometimes appear in plain sight too while exploring.
* TheStinger: [[spoiler:After the credits roll in the demo, you'll be treated to a sneak peak at the next area, Starlight Isles--after wandering through a forest, Chara finds themself cornered by Sans (in his Crossbones persona). The scene then ends, with Sans and Papyrus providing some [[BreakingTheFourthWall fourth wall-breaking commentary]] on the scene and telling the player to wait for the full game.]]

* Pacifist route
* Genocide route
* Aborted Genocide / "Evacuation Neutral" route

* AdaptationalBadass: 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: 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.

* AmbiguouslyEvil: Downplayed with [[spoiler:Flowey]] in the demo because his motives in the game have yet to be revealed. It's made pretty clear he's [[spoiler:still not a sweet and innocent flower even in this world, between him hinting that Chara will need to kill to survive, Temmie thinking he's put Chara up to their actions in Genocide and admitting to envying him as a rival in that ending, and in Neutral him not perturbed in the slightest if Chara betrayal-kills Asgore, still saying that Chara is like him and admitting to being no better than the Temmies sometimes. Still, he chases the Temmies off before they can gang up on Chara when he didn't need to, makes no move to attack Chara and take their SOUL himself, and instead is set up as an ally to them and an enemy to the Temmies for the full game. Since his ultimate goals are unknown, it's not clear if Flowey is biding his time playing a longer con on Chara than his Undertale counterpart pulled on Frisk, or if he will be a sort of [[AntiHero morally lax ally]] leaving the active villainy up to the Temmies.]]
* AmbiguousSituation: Whether it is [[spoiler:the player or Frisk compelling Chara to leave Ruined Home]]. Since Chara and Frisk are swapped, it would make sense for Frisk [[spoiler:to have more of a presence in Neutral and Pacifist like how Chara has more of a presence in Genocide]], but statements from Team Switched indicates the [[spoiler:player may be an InUniverse force and since '''we''' want to progress the game by leaving...]]

* BewareTheNiceOnes: Asgore will not hesitate to kill you on a genocide run, and if you spare him and then try to enter his house, he'll angrily yell at you to GetOut

* BigDamnHeroes: Asgore accidentally saves you from Temmie when they try and kill you, forced to flee when they hear him coming, and [[spoiler:when seven of them try to gang up on you, ''Flowey'' pops up to defuse the tension by threatening to call Asgore on them. In Genocide, the Temmie that didn't flee tries to kill both Chara and Flowey, only for the flower to effortlessly one-shot them with a pellet and knock them away.]]

* CorruptTheCutie: Seems to be the case with Chara, [[ThisIsYourBrainOnEvil influenced by LV]] and [[DemonicPossession under the control of the player]], in Genocide.

** [[spoiler:Chara's dialogue options in Neutral and Pacifist show they want to stay with Asgore and are confused and scared when the dialogue keeps changing to them pressing him on how to leave, with them trying to plead for help by the end. Regardless of whatever [[AmbiguousSituation the possessing entity's]] intentions are, it's clear that Chara is frightened all the same]].
** This [[AmbiguousSituation may]] be happening in Genocide as well. [[spoiler: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]].

* EvilVersusEvil: Temmie wants to work with Genocide Chara just like Flowey did in the original game, only here they find out a lot quicker that Chara isn't interested in being friends.
* FaceFramedInShadow: Chara's face becomes covered by a shadow once Genocide is triggered, with their [[HiddenEyes eyes hidden]]. In an aborted Genocide run, Chara's eyes become visible again but their face remains eerily shadowed, creating the appearance of them having a ThousandYardStare.
* 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.

* 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.]]

* KidnappedByTheCall: [[spoiler:Happens to Chara in the Pacifist and Neutral routes, with them forced by a force controlling them to leave a happy life with Asgore in Ruined Home.]]

* MonsterCompendium: One part of the journal is dedicated to the monsters that are encountered in the game, with the information changing depending on what you do. For example, if you flee from the first type of enemy you encounter, there won't be much information until you encounter another one and don't flee from it right away, and if you're playing a neutral run then any monsters you kill will have their status as "killed", but if you're doing a Genocide run it will instead say "eradicated". Some monsters that aren't fought when you first meet them (or even at all) will also have entries added.

** Chara's [[FaceFramedInShadow shadowed face]] in Genocide might reference up to three! Their face is hidden this way in flashbacks showing them from the front in ''Undertale'', in the debug build of ''Undertale'' there exists a sprite that looks like a cross of Frisk and Chara with a shadowed face who you can make show up instead of Frisk's reflection,[[note]]Especially interesting considering the run this shows up in for TS!Underswap is that the debug build sprite is commonly theorized by fans to have been a scrapped feature where Chara (or this faceless mishmash of Chara and Frisk) would've replaced your reflection after you completed Genocide and sold Frisk's SOUL[[/note]] and Kris has an almost perpetually shadowed face when you're controlling them in ''Deltarune''.
** When fighting Asgore on a genocide run, [[spoiler: his final attack is taken from one of Toby Fox's earlier ideas as seen in the artbook, as is the terrifying face he makes during it]].

** [[spoiler: Asgore makes a scary face during his final attack on a genocide run, as a reference to one of Toby Fox's original concepts]].

** and Pacifist, when you chose not to fight and spare everyone.
** Genocide, when you exhaust the kill count in Ruined Home.
** Aborted Genocide, when you exhaust the kill count in Ruined Home, but spare Asgore.
