** The Riverperson's warning to "beware the man who speaks in hands" is almost universally believed to refer to Gaster, but it's not as clear-cut as the fandom would have you believe, considering that this would make the Riverperson the only character to talk about Gaster besides his followers, and not every symbol used by Gaster is a hand. Another of the Riverperson's warnings, "beware the man who came from the other world", is similarly questionable; it could refer to Gaster since he doesn't reside in the world of ''Undertale'', but he also isn't really ''from'' another world as far as we know, he's just not in this one. Unlike the former quote, there are alternative candidates for this, mainly Sans, So Sorry, or Chara.

* 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 actively try to kill you, it's not too weird to start killing in self defense and then just keep doing it.

* KnightOfCerebus: In any kind of run that's not Pacifist (a.k.a. did not kill everyone). Not only is there a good chance you have a huge body count behind you, but the Underground changes hands, and always for the worse — it can devolve from tyranny to anarchy to becoming an {{Egopolis}} and everything in-between. And you are the one who started it. And that's not even getting to the Genocide/No Mercy run, where you basically [[spoiler:destroy reality]].

* HopeSpot: They made it the farthest of all the humans who came through the Underground...but in the end, they still died, just like those who came before them.

* TheLastOfTheseIsNotLikeTheOthers: Inverted with the Memoryheads being the first thing you encounter. Unlike the other Amalgamates, the Memoryheads do not share different parts of monsters you've seen throughout the Underground and cannot be spared with the actions according to their component species, instead being spared by interacting with your cellphone, and their ACT menu is lifted from your overworld menu.

* TheLastOfTheseIsNotLikeTheOthers:
** Gaster Follower 3 is the only one who is not a PaletteSwap of another NPC... [[SubvertedTrope that is, until]] ''VideoGame/{{Deltarune}}'' released, as a hunched-over bird NPC in that game appears to be the "normal" version.
** Clam Girl transforms into her goner counterpart, rather than existing separately from her.

* ManBitesMan: Lemon Bread's primiary method of attacking you is by distorting the bullet board into their fanged mouth and using it bite down on the soul.

* TheDarkSide: You '''are''' the Dark Side, feeding Chara power and corrupting them into evil and being the Antichrist to your SatanicArchetype at the same time. (Only in the genocide run or when you kill somebody, really.)

* GoodIsNotSoft: While it is encouraged to be spare as many monsters as you can, however, [[LoopholeAbuse there is nothing from stopping you from]] [[PayEvilOntoEvil beating up the ones that want or deserve to be beaten up,]] and [[SaveTheVillain you can still spare them once their HP is low enough.]]

** It's possible for the trope to still be played straight after the player accepts Sans' false offer of mercy, ''if'' the player takes the skeleton's words to heart and RESETS after getting dunked on. Of course, this depends entirely on you.

'''No'''\\

* VillainousBSOD: A very, ''very'' common reaction — the [[IntendedAudienceReaction intended reaction]], even — for those who play the Genocide route, especially those who had no idea what they were getting into. Some choose to [[HeelFaceTurn reset and undo their mistakes at that point]], while others choose to [[IgnoredEpiphany grit their teeth and press on anyway]].

* OurZombiesAreDifferent: They are essentially undead monsters.

* AllThereInTheManual: In VideoGame/Deltarune, we are give the names of a few of the monsters that compose the amalgmates as they are written on the tombstones of their [[DeadAlternateCounterpart expired selves]]. The name of Snowdrake's Mother is Crystal, Shyren's sister is called Shyra, and the biggest dog within Endogney is named Muttler.

* DarkReprise: Unlike the other Amalgamates, which use the DrumAndBass track "Amalgam" as their battle theme, Endogeny and CrystalDrake are respectively fought to heavily distorted versions of the goofy "Dogsong" and the tranquil "Snowy".

* GeneticAbomination: Although ultimately LovecraftLite, their powers are definitely more on the EldritchAbomination end of the fence. Their encounters play out like video game glitches, with bizarre names and strange dialogue. The Memoryheads' ACT options are your menu buttons until you use the "CALL" command. The Reaper Bird's flavor text and dialogue is multiple overlapping lines of text, and is initially only called ",". [[NotMakingThisUpDisclaimer Yes, just that one punctuation mark.]] Lemon Bread's dialogue comes from 12 separate speech bubbles covering the top of the screen. If you try to ignore Endogeny, the flavor text says he appears everywhere you look, and trying to talk to Snowdrake's Mother will often result in the dialog box describing you as doing things much more extreme than the command suggested.

* KnightOfCerebus: Their appearance marks one of the darkest and scariest segments of the game and its backstory.

* PunnyName: En'''dog'''eny. It's comprised of the parents of the Royal Guard dogs.

* TheUnintelligible: The Reaper Bird begins speaking with multiple dialogues overlapping over each other. It eventually separates into the individual components if you spare it. The Memoryheads can also speak in a [[BlackSpeech horrible distorted screech that resembles a dial-up modem]], but comes in fine through the cell phone.

* BlobMonster: Endogeny is described as being amorphous, and is a vaguely dog-shaped blob that can disperse itself into floating particles. Much of the other Amalgamates tend to be more Downplayed cases, having a sort of "melting" effect from the experiments and having the ability to shapeshift.

* DarkReprise: Unlike the other Amalgamates, which use the DrumAndBass track "Amalgam" as their battle theme, Endogeny and Snowdrake's Mother are respectively fought to heavily distorted versions of the goofy "Dogsong" and the tranquil "Snowy".

* EyeScream: Snowdrake's Mother has ''Vegetoid faces'' in the place where a Snowdrake's eyes would be.

* DarkIsNotEvil: They're terrifying to look at, the reason behind their existence is horrifying, and the sequence in which you meet them is probably the closest the game ever comes to being a straight-up horror game… but none of them seem to sincerely ''want'' to hurt you (outside of ''maybe'' Lemon Bread, and even then that's more you being the first target for… [[PronounTrouble their]]… frustrations in years), they all back off once Alphys tells them to, and at the end of the pacifist route, their happy ending is simply being with their families again. They're creepy, sure, but not truly malevolent, or are only truly dangerous [[CentralTheme should you panic and not attempt to understand them]].

* MeaningfulName: Lemon Bread is named after a type of pudding, and one of its constituent parts is Moldbygg, a gelatin monster.

* ThrowTheDogABone: Talking to him while holding an umbrella makes him feel less miserable about his situation.

* FightingAShadow: The main reason why no one can hurt ''you'', no matter how badly they want to. You'rre in Real Life, a literal higher plane of existence, using Frisk as your avatar in the game world; how are they supposed to reach you, much less do you harm?

* 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, ''Su[[InconsistentSpelling sie]]'' debuts as a deuteragonist in ''VideoGame/{{Deltarune}}''.

* UnknownCharacter: Clam Girl's neighbor and their daughter Suzy. No information is revealed about either of them, for all we know they could be just an InventedIndividual. We do meet ''Su[[InconsistentSpelling sie]]'' in ''Deltarune'', but we haven't gotten any information on Susie's family yet, and it's not even clear if [[OneSteveLimit this is the same Suzy]].

'''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]]\\

* 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, Su''[[SpellMyNameWithAnS sie]]'' debuts as a deuteragonist in ''VideoGame/{{Deltarune}}''.

* UnknownCharacter: Clam Girl's neighbor and their daughter Suzy. No information is revealed about either of them, for all we know they could be just an InventedIndividual. We do meet Sus''[[SpellMyNameWithAnS ie]]'' in ''Deltarune'', but we haven't gotten any information on Susie's family yet, and it's not even clear if this is the same Suzy.

* NominalVillain: Similar to the above trope, you don't have to be genuinely malicious while going through a Genocide route because of an obligation to see everything the game has to offer.

[[folder:Dr. W.D. Gaster]]
!!Dr. W.D. Gaster

The enigmatic Dr. W.D. Gaster was the original Royal Scientist, before Dr. Alphys. Can't find him? Well, that's no surprise--he's barely in the game.

Either way, what follows is the mysterious tale of a brilliant mind who fell into a creation of his that accidentally caused him to be shattered across reality, with his fate uncertain. Even to this day, no one knows the complete story of W.D. Gaster... well, no one that wants to talk, anyway.

* KarmaHoudiniWarranty: DoubleSubversion. If you reach the end of the Genocide Run, you'll have essentially used Frisk to wipe out the entirety of the Underground, only to meet The Fallen/Chara, who proceeds to kill you alongside ''the entire world'' with one swing. If you wait long enough in the post-Genocide Run game window, Chara will give you a choice to start anew in exchange for your soul, which ''seems'' like a subversion at first. Get to the end of the True Pacifist route here, however, and Chara/The Fallen will take control of Frisk and kill everyone anyway, ensuring you ''can't'' get the happy ending you worked so hard to get.

Originally, if one were to explore the game's files, they'd come across a few odd [=NPCs=], rooms, and messages that appeared to be cut content... though after the Internet took note of them, they were changed to extremely rare {{Random Event}}s instead.

** 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 does seem to be the best match for them, as his speech 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. (An alternative candidate for the latter quote is Sans.)

* RatedMForManly: The Manly Bandanna has abs drawn on it, and the Tough Glove summons a bunch of fists in its attacking animation.

** room_water_redacted, or Room 272, is a blank, empty room with a mysterious figure in the middle of it. Regardless of whether the character itself has ties to Gaster (it only says a single word in Wingdings, being "[REDACTED]"), the room's exit leads to the Sound Test, the one place in the game where you can listen to Gaster's Theme.

The enigmatic Dr. W.D. Gaster was the original Royal Scientist, before Dr. Alphys. Can't find him? Well, he's not really around anymore. Originally, if one were to explore the game's files, they'd come across a few odd [=NPCs=], rooms, and messages that were cut. Eventually, some of these were reinserted into the game as incredibly hard to find EasterEggs that depended on luck.

* TheGhost: Suzy, the Clam Girl's neighbor's daughter. [[SurpriseCreepy Goner Clam Girl]] [[WhamLine hints you]] [[VaguenessIsComing might meet her soon]]...

* SurpriseCreepy: The Clam Girl, when she transforms into her goner counterpart, appears with a single, bloodshot eye in place of her head.
