    Dummy 
https://static.tvtropes.org/pmwiki/pub/images/dummy.png
It doesn't seem much for conversation.

A cotton heart and a button eye, you are the apple of my eye.


  • Chekhov's Gunman: They turn out to be a ghost possessing a dummy, and Mad Dummy's cousin.
  • No Name Given: Even Mad Dummy doesn't remember their name.
    What was their name again...?
  • Screw This, I'm Out of Here!: They will tire of your aimless shenanigans and float away if you keep wasting your turns without talking to or attacking them. This is because they're possessed by a ghost.
  • Shrinking Violet: According to Mad Dummy; if you fled from the fight, Mad Dummy says they were "a shy sort" and that this "broke their little ethereal heart."
  • The Voiceless: They're a dummy. Even after you learn that they probably should be able to speak, you can never interact with them beyond your first battle anyway. There are talking Dummies in New Home, and their cousin is a dummy that talks.

    Froggit 
https://static.tvtropes.org/pmwiki/pub/images/froggit.png
Ribbit, ribbit.

Life is difficult for this enemy.


  • Book-Ends: Discounting Flowey and the Dummy, Froggit is the first actual "random"note  enemy to appear. A lone Froggit is the last monster to appear when telling you the story of Asriel and the Fallen Child, just before you meet Asgore. It is also the last monster (outside of Asriel) you see in a post-pacifist ending, where the Froggit that asks you to spare the monsters will say how proud of you it is.
  • Deliberately Monochrome: Curiously, it's always this, unlike virtually every other enemy outside of battle.
  • The Ditz: The Froggits that talk to you are not this, as they provide valuable advice to the player character. Any one that fights you, though...
    Froggit doesn't seem to know why it's here.
  • Eyes Do Not Belong There: Pay attention to a Froggit's animations (especially when Toriel scares one off for you) and you'll notice that it has eyes on its underbelly.
  • The Goomba: The first "real" enemy you encounter. It's not quite as easy to deal with as Whimsum, but given that you actually need to try to spare or defeat a Froggit, it serves the role better.
  • Punny Name: Its name is a portmanteau of "Frog" or "Frogger" and "Hermit" or "Kermit".
  • Zero Effort Mook: The first Froggit you face gets scared off by Toriel after one turn.

    Whimsun 
https://static.tvtropes.org/pmwiki/pub/images/whismun.png
Forgive me...

This monster is too sensitive to fight...


  • Apologetic Attacker: The only reason it's attacking you is because it feels obligated to do so, and it will let you know this with its battle dialogue.
  • Driven to Suicide: Seems to be on the verge of it, given how pathetic it is. One of its encounter lines is “smells like mothballs and lavender.” These substances are both used to kill moths, which Whimsun resembles.
  • Fragile Flower: So meek that attempting to console it is enough to make it flee.
  • Harmless Villain: If you can even call it that. It makes no effort whatsoever to harm you if you stand still.
  • Zero Effort Mook: As a direct consequence of the above point, it's extremely easy to spare.

    Moldsmal 
https://static.tvtropes.org/pmwiki/pub/images/moldsmal.png
*Sexy wiggle*

Stereotypical: Curvaceously attractive, but no brains...


  • Artifact Mook: Appears in Waterfall as a slightly stronger enemy... which is a moot point, because by now, you can probably tell that they can be Spared without even using the ACT menu. Their main purpose is to make Moldbygg a more surprising encounter (because Moldbygg looks like a Moldsmal at first, but can't be Spared instantly).
  • Blob Monster: One that looks like lime jello.
  • Brainless Beauty: A parody of the concept, as the description demonstrates.
  • Palette Swap: Parodied; according to Check, the Waterfall Moldsmals are a different color, which obviously means they're stronger. Not like you can see the former trait.
  • Portmanteau: Their name is a combination of "Mold" (as in a jello mold) and a misspelling of "Small" (reflecting their small size).
  • Spread Shot: It can do an "Exploding Shot" version, where it fires several bullets that split apart into eight smaller bullets in all cardinal and diagonal directions.
  • Underground Monkey: Slightly stronger variations appear in Waterfall, though there's no other differences between them and the Ruins versions.
  • Zero Effort Mook: You're usually able to spare them from round one. If not, you may be dealing with a Moldbygg.

    Loox 
https://static.tvtropes.org/pmwiki/pub/images/loox.png
Please don't pick on me...

Don't pick on him. Family name: Eyewalker.


    Vegetoid 
https://static.tvtropes.org/pmwiki/pub/images/vegetoid.png
Farmed Locally, Very Locally

Serving Size: 1 Monster. Not monitored by the USDA.


  • An Aesop: It constantly reminds you to eat your greens. The fact that its green attacks heal you takes this further.
  • Ambiguous Syntax: Vegetoid's here for your health.
  • Anthropomorphic Food: That apparently likes to offer monsters not-so-anthropomorphic food.
  • Creepy Good: It's a strange, frightening-looking sentient vegetable that pops up out of the ground to battle you. It also reminds you to eat your greens and will happily feed you if you ask.
  • Eating the Enemy:
    • One of the ways to defeat Vegetoid monsters is to use the "Eat" action on them. However, this doesn't kill them, since the player character only takes one bite.
    • In the demo, however, this kills the Vegetoids, especially when you cannot SPARE until its health is low enough.
  • Eat the Dog: In the demo, this was a (lethal) option to end the battle with a weakened enemy. In the final game, you'll simply take a bite out of its body, ending things relatively peacefully and restoring some of your health.
  • Edible Ammunition: Pelts you with lethal veggies, unless you ask for a meal, in which case it pelts you with lethal veggies and a single green one that heals you, instead.
  • Evil Laugh: It "cackles", anyway.
  • Helpful Mook: Enforced. One of the ways to spare it is to ask for "Dinner" and "eat your greens" (literally, one of its bullets turns green and restores 1 HP when it hits you).
  • The Voiceless: Averted, despite insisting otherwise.
    Vegetoid: Plants Can't Talk, Dummy

    Migosp 
https://static.tvtropes.org/pmwiki/pub/images/migosp.png
HEED THE SWARM.

It seems evil, but it's just with the wrong crowd...


  • Big Creepy-Crawlies: It's a large beetle that summons smaller bugs to attack.
  • Dance Battler: Subverted. While it will dance during battle, it's only after the other enemies are gone and it's just expressing itself. And since it doesn't move from its spot, the player can only take damage from the dancing Migosp by deliberately making contact with their SOUL.
  • Hive Mind: It calls the main character a "Filthy Single Minder." It itself, apparently, only is part of one when another enemy is on the field.
  • Peer Pressure Makes You Evil: It only attacks when other enemies are around. If it's the only enemy left on the field, it talks about how it can finally be itself and just starts dancing for the rest of the fight, becoming sparable.

    Snowdrake 
https://static.tvtropes.org/pmwiki/pub/images/snowdrake.gif
Ice puns are "snow" problem!

This teen comedian fights to keep a captive audience.


  • In-Series Nickname: He's called "Snowy" by the few people who talk about him. It becomes important when you encounter his mother, as her barely managing to say it confirms the two are related.
  • Kansai Regional Accent: Speaks with heavy Kansai-ben in the Japanese translation, due to the dialect's association with comedy acts and Kansai-speaking comedians.
  • Kick the Dog: One of the ways to "spare" Snowdrake is to just heckle him repeatedly. It eventually culminates in you telling him that nobody will ever love him the way he is now, at which point he becomes despondent and runs away.
  • Missing Mom: Mentioned by his father. She ended up as one of the Amalgamates in the true lab.
  • Pungeon Master: He constantly makes ice puns. His father is a comedian in Hotlands, and is ashamed of him for it.
  • Punny Name: His head is designed like a snowflake, and he's a dragon-bird monster ("drake"). Sometimes he'll realize mid-fight that his own name is an ice pun as well.
  • Unique Enemy: A minor example: if you kill him, all other encounters that would include him will have the functionally identical Chilldrake in them instead.
  • "Well Done, Son!" Guy: Laughing at his jokes prompts him to proudly proclaim that "Dad was wrong!"

    Chilldrake

NEVER do your homework!!

Rebels against everything!! Looking for its friend Snowy.


    Ice Cap 
https://static.tvtropes.org/pmwiki/pub/images/icecap.png
I just loooove my hat, okay?

This teen wonders why it wasn't named "Ice Hat".


    Jerry 
https://static.tvtropes.org/pmwiki/pub/images/jerry.gif
Man, you guys SUCK at this.

Everyone knows Jerry. Makes attacks last 2 seconds longer.


  • Asshole Victim: Should you choose to kill them, they pretty much had it coming given their unpleasant and annoying personality.
  • The Friend Nobody Likes: The battle text notices that the other monsters sigh exasperatedly whenever Jerry is around. You can even conspire with the other monsters (unintentionally) trying to kill you in order to ditch it. It's taken to the point where it doesn't even get a place in the end credits.
  • Full-Frontal Assault: As revealed by its Tarot card, Jerry is completely naked while fighting you.
  • Gonk: Has an intentionally-gross design to match its personality.
  • Hate Sink: Jerry is deliberately obnoxious and hard to get rid of (lethally or otherwise), so you can understand why its "allies" hate it. Sparing it, while possible, is far more difficult than plain ditching it when it's not looking. You and the other monsters celebrate escaping Jerry.
    (After ditching Jerry) You and the other monsters celebrate Jerry's Disappearance.
    • Even Chara hates Jerry, as in a Genocide route they can spare it so they can find another monster to kill rather than spend time with Jerry.
  • Jerkass: It acts obnoxious during battle, so you can see why the other monsters hate it.
    Jerry eats powdery food and licks its hands loudly.
    Jerry sneezes without covering its nose.
    Jerry tells everyone that he's going to the bathroom.
  • My Friends... and Zoidberg: It's introduced separately from other monsters, usually in a derogatory or at the very least dismissive manner ("Jerry came too").
  • The Scrappy: In-Universe. Not a single creature even remotely likes it; it's rude, unhygienic, and generally a jerk.
  • Screw This, I'm Outta Here!: The main way to SPARE it, via the "Ditch" ACT. The other monsters in the fight join you because they don't want to deal with it either. Take too long in Fighting or Sparing them, and Jerry will return to the fray.
  • Shaped Like Itself: Some flavor text says, "Smells like....... Jerry."
  • Stone Wall: Has 0 attack, but very high defense for that point in the game. This was likely done to make even Genocide players despise it. Makes the one way you can spare it much easier, though.
  • Support Party Member: Its only combative function is to lengthen the attack phase of its "allies".

    Gyftrot 
https://static.tvtropes.org/pmwiki/pub/images/gyftrot.gif
Hohohoh! Go ahead and laugh...

A much-maligned monster.


  • Butt-Monkey: Teenagers have covered its antlers in junk, and it's put it in a bit of a foul mood. You can remove the junk yourself, but it'll just accumulate more later.
  • I Choose to Stay: It stays in the Underground during the True Ending so it can finally have some peace and quiet. If you removed all of its decorations, it'll leave eventually and become a Christmas display.
  • An Ice Person: Can attack with snowflakes.
  • Kick the Dog: You can put even more decorations on it, much to its dismay. You can only put googly eyes on it. Attempting to decorate more will have the flavor text declare "You can't improve on perfection." If you remove decorations from Gyftrot and then redecorate, it'll feel betrayed.
  • Pet the Dog:
    • The citizens of Snowdin have noticed its plight and dedicated a tradition to him where they decorate a big tree and put presents underneath it. Gyftrot doesn't appreciate the sentiment, especially since they haven't actually helped it at all.
    • You can give it money once you've removed the decorations off its antlers.
  • Shell Game: One of its attacks is this, with gift boxes. The correct box in this case turns into a blue projectile, meaning you can just stand still and dodge it when it flies upwards with the other boxes.

    Snowdin Canine Unit 
https://static.tvtropes.org/pmwiki/pub/images/dogs2.png
♥ * Pet

Doggo, Lesser Dog, Greater Dog, Dogamy, and Dogaressa (the latter two often being called the "Dogi"). A series of armored dogs guarding the path from the Ruins to Snowdin.


  • Achievements in Ignorance: Lesser Dog can be found at Grillby's playing a game of Poker against itself. And losing. By the Playable Epilogue, it finally manages to beat itself.
  • Admiring the Abomination: In the True Pacifist Ending, Doggo has no problems at all with his long-lost relative. Said relative is Endogeny, who is more or less an undead blob monster, and Doggo's happy that he can see it since it's constantly moving.
  • Ambiguous Gender: Lesser Dog and Greater Dog are only ever referred to as "it".
  • An Axe to Grind: Dogamy and Dogaressa wield giant axes that have eyes on them. They slam them down for one of their attacks.
  • Animated Armor: Or maybe a Mini-Mecha. The big, hulking Greater Dog is actually a normal-sized dog riding a massive suit of armor.
  • Battle Couple: Dogamy and Dogaressa are married.
  • Big, Friendly Dog: Greater Dog looks gigantic and intimidating, but all it wants is some TLC, and will gladly leave you alone when it gets some.
  • Blade on a Stick: The Greater Dog's weapon. It even has a dog face on it! Lesser Dog uses them to attack, but it holds a dogger in its battle sprite.
  • Boss Remix: The song that plays during Greater Dog's fight is a slowed-down version of "Dogsong", the regular fight theme re-orchestrated using dog barks from the Mario Paint soundfont.
  • Canis Major: Greater Dog, and to make the reference to the stars complete, Lesser Dog. Subverted when it turns out it's just a sort-of big dog riding around in a disproportionately large suit of armor.
  • Critical Hit: Parodied when you pet Lesser Dog enough to spare it, at which point the game text informs you that it's a "critical pet!"
  • Dark Is Not Evil: Doggo looks like a typical gangster with wacky clothing and knives as his signature weapon. He's just as friendly as the other dog-type monsters. It's been speculated that he only dresses up like that because his reverse motion blindness (can only see moving things) makes him unaware of what he's wearing.
  • Department of Redundancy Department: Lesser Dog has six Act options; "Check", "Pet", "Pet", "Pet", "Pet", and "Pet". Hmm, how could it possibly be Spared...?
  • Dogs Are Dumb: Varies. Lesser Dog and Greater Dog have mental capabilities only slightly higher than a non-anthropomorphic dog (although the latter is a non-anthro dog). Doggo is smarter, but his inability to see unmoving things hampers him, and he thinks the former two dogs are much smarter than they actually are. The Dogi seem to be the smartest overall, but even they aren't too complicated, allowing you to fool them into thinking that you're some kind of puppy if you roll around in the snow.
  • Dual Boss: Dogamy and Dogaressa, reflected by their attacks having two parts. Depending on which one you kill first (if you decide to kill them), the other will change their attacks based on their reaction to the other's death. Dogaressa flies into a rage; Dogamy just mourns...
  • Evil-Detecting Dog:
    • The Dogi have great noses when it comes to smelling for potential human intruders, which is why they attack you in the first place. Fortunately, wallowing in the dirt will get rid of the human scent and help when Sparing them.
    • Doggo can't see things that are standing still, with one exception; he will feel something very wrong and become afraid when the player approaches him on a No Mercy run. This is the first true sign of how the player's Killing Intent works.
  • Foreshadowing: When in battle, the Dogi may reveal that they were runner-ups in a nose-nuzzling championship. You later learn who came first: Asgore and Toriel.
  • Fun T-Shirt: The Dogi have each other's faces on their robes, unseen on their overworld sprites and only noticeable if you SPARE them or kill one of them, as their axes cover the other's chest in their battle sprites.
  • Gameplay and Story Integration: Doggo's inability to notice stuff that isn't moving is reflected in his blue attacks, which cannot harm a stationary player. If the player does get hit by them, they got noticed and he uses regular white attacks.
  • Gentle Giant: The Greater Dog is described as such when spoken about in Grillby's, and if played with and petted is more than content to lie down in the Child's lap... while wearing its hulking suit of armor.
  • Go Fetch: Use the Stick on any of them, and they'll run after it, allowing them to be Spared instantly.
  • Gratuitous Japanese: When you pet Doggo, the word WAN floats around him as he freaks out. 'Wan' is the Japanese onomatopoeia for a dog's barking.
  • The Guards Must Be Crazy: While none of them are weak, they seem to have a hard time actually guarding anything, thanks to their dog instincts. Papyrus comments on it while talking about Lesser Dog in one phone call.
    Papyrus: This dog loves to be pet. That's its defining personality trait. Wait, why are they a Royal Guard and not me!?
  • Happily Married: The Dogi. One of the battle comments is that they are "saying sickeningly sweet things to each other".
  • Heroic BSoD: Killing Dogaressa will cause Dogamy to become depressed, and his attacks become completely impotent. On the flipside, Dogaressa slips into an Unstoppable Rage and gets even more powerful if Dogamy dies.
  • Incest Is Relative: Since all the dog parents were fused together into the Endogeny Amalgamate, Dogamy and Dogaressa ponder the implications of how they are technically related now. They dismiss it because it is common among dogs.
  • Keet: Lesser Dog, who gets excited when you pet it. Really, really excited.
  • The Last of These Is Not Like the Others: Lesser Dog is considered "separate" from the others in several ways. It doesn't play poker with the others, It is a random encounter instead of appearing with a cutscene, and it doesn't appear outside of Grillby's with the other dogs and Endogeny in the True Pacifist ending.
  • Leaning on the Fourth Wall: Doggo can't see things that aren't moving. If you try to talk to him, he gets jumpy and asks "Who's there?!" He can't see who's talking to him... because you can't move during dialogue.
  • Leitmotif:
    • The Greater Dog has "Dogsong" playing during its encounter.
    • "Dogbass" plays as the Dogi investigate the area, just before they attack.
  • Living Motion Detector: Doggo can only see things that are moving, a point very much stressed in the early-game to teach you about blue attacks.
  • Long Neck: Most of the humor value of a pacifist Lesser Dog encounter. The more you pet it, the more its neck telescopes out. With enough patience, its head can even go out of the top of the game screen, back down, and through the bottom.
  • Mini-Boss: All of them sans Lesser Dog are unique and are required encounters. Only the Dogi and Greater Dog take much effort to Spare or Fight, however.
  • More Deadly Than the Male: When fighting the Dogi, if you kill Dogaressa first, then Dogamy loses almost all will to fight and becomes a pushover. However, if you kill him first, Dogaressa becomes much more dangerous and harder to beat.
  • My Friends... and Zoidberg: Lesser Dog seems to be the Zoidberg of the Dog group. None of the other dogs mention it, and it appears as a random encounter enemy rather than a mini-boss encounter. It's also the only dog not to meet Endogeny; at the end of the game, it's still inside playing poker against itself. The NPC near Lesser Dog's station can also comment that Lesser Dog always ends up playing poker alone because it doesn't know how to express itself with the other dogs.
  • My Instincts Are Showing: Despite all of them being at least intelligent enough to wear clothes, they all love being petted and chasing sticks.
  • The Nose Knows: The Dogi depend almost entirely on their sense of smell to identify intruders. A crucial part of sparing them involves rolling around to disguise your scent.
  • No Smoking: Played for Laughs (considering smoking occurs elsewhere in the game), Doggo has a fondness for smoking dog treats, of all things.
  • Not So Stoic: Doggo seems pretty serious when you first meet him... and then you pet him, and anything that made him imposing vanishes.
  • Oh, Crap!: Doggo has this reaction when he's pet by something he's inferred to not exist. (Or at least not see.)
  • Overly Long Gag: Lesser Dog's neck-stretching gag can go on for a very long time and yield unique lines long after you can Spare it. It will also keep cropping up during the game afterwards.
  • Punch Clock Villains: Once the player reaches Snowdin, they can all be found hanging out at Grillby's, and don't seem to care at all that you're there.
  • Punny Name:
    • "Dogaressa" is the female form of "doge". "Italian ruler" doge, mind you, not that doge.
    • "Dogamy" is a pun on the suffix "-gamy" being used for different types of marriage (monogamy, polygamy, etc.), as Dogamy and Dogaressa are married.
    • A subtler one in Doggo's case — "doggo" is somewhat archaic slang meaning "to remain motionless and quiet to escape detection" (i.e., exactly what you need to do when facing Doggo).
    • In a very downplayed example, Lesser Dog's 'dogger' is made of 'pomer-granite'.
  • Quirky Miniboss Squad: The royal guard all have weird quirks. Doggo's vision problems, Greater Dog's tendency to act like a regular dog, Dogamy and Dogaressa being Sickeningly Sweethearts, and Lesser Dog's increasingly long neck.
  • Real Men Wear Pink: Doggo, the most threatening of the dogs in appearance, wears a pink shirt with a dog face on it.
  • Roaring Rampage of Revenge: If Dogamy is killed before Dogaressa, Dogaressa flips out and becomes much more relentless in her attacks.
  • Rummage Sale Reject: In contrast with his squadmates (who wear armor or cloaks), Doggo wears a ridiculous outfit of a pink sleeveless shirt with a dog face on it and leopard-print pants. Fans tend to agree that his inability to see still objects causes him to wear things like this.
  • Saying Sound Effects Out Loud: Unsound Effects, rather. Lesser Dog's speech, if one can call it that, consists of sounds spoken out loud, like "pant pant" or "excited noises." As you keep petting it, it starts making sounds that no dog can or should make, including "plane takeoff" and "kettle whistling".
  • Screw This, I'm Outta Here!: If you ignore Greater Dog for several turns, it will leave out of boredom.
  • Shields Are Useless: Despite carrying around a shield the size of itself, Lesser Dog has the lowest Defense out of all of them.
  • Sickeningly Sweethearts: The Dogi are said to call each other overly cute names during battle.
  • Spell My Name with a "The": In-battle text refers to the female of the Dogi as "the Dogaressa".
  • Stealth Pun: They're guard dogs.
    • One of Greater Dog's attacks is a tiny sleeping dog. If you move at all, you'll wake the dog and cause it to attack. Let sleeping dogs lie.
  • Stellar Name: Lesser Dog and Greater Dog's names derive from the English translation for the names of the dog constellations, Canis Minor and Canis Major.
  • Tertiary Sexual Characteristics: Dogamy has Big Ol' Eyebrows and a pseudo-mustache, while Dogaressa has long eyelashes. They're nearly identical otherwise.
  • Theme Naming: All of them have "Dog" in their names. This carries over to Endogeny late in the game.
  • Tiny-Headed Behemoth: Greater Dog initially seems to be this. It's actually a normal-sized dog wearing a giant suit of armor.
  • Top-Heavy Guy: Greater Dog, whose chest and arms are gigantic compared to its positively tiny head and legs. Except that it's actually just a regular-sized dog in some sort of pilotable armor.
  • Truth in Television: Doggo's inability to perceive static objects is a real-life disorder.
  • Unique Enemy: Lesser Dog, unlike the other dogs, is fought in a random encounter on one screen. It's otherwise still a mini-boss, albeit one of the simplest ones.
  • Vocal Dissonance: The Greater has a very deep bark, which is fitting for the kind of person who would normally wear armor as big as it does, but not for the average-sized dog it actually is. Unusually, this goes both ways, in that Greater Dog introduces itself from its snow poff by sticking its head and tail out, then giving a couple of high-pitched, yappy barks, which makes it seem cute... until it reveals that it somehow hid its entire massive body underneath the snow. This makes it seem like a squeaky-voiced titan instead.
  • Warm-Up Boss: All of them teach you a different mechanic that's important to know going forward. Doggo teaches you about Light Blue attacks that don't hurt you if you stand still: if you didn't encounter a Vegetoid in the Ruins, this is the first non-white bullet you'll see. The Dogi teach you that certain ACT commands change in response to other ACT commands and thus you'll have to do this sequentially to get to them to back down. Lesser Dog's use as a tutorial is questionable, since it stops fighting after the first pet, but repeatedly petting it shows that repetition can have different effects. And Greater Dog combines all of these, using Light Blue bullets, having ACT commands that change in response to previous ACT commands, and requiring the same ACT to be used multiple times to spare it.
  • Weaksauce Weakness: Petting plays a significant role in scoring a Pacifist victory against all of them. They're also all vulnerable to a thrown stick. Doggo, in particular, can't hurt you if you hold still.
  • Weapons-Grade Vocabulary: One of the Greater Dog's attacks is a tiny sleeping dog that, if woken up by moving, will send damaging "BARK"s at your SOUL.
  • What Kind of Lame Power Is Heart, Anyway?: Doggo is really good at sensing motion. And that's literally the only thing he can see, so anyone standing perfectly still is completely invisible to him (and this is reflected in his attacks, which are all of the blue variety and can be avoided by standing still).

    Glyde 
https://static.tvtropes.org/pmwiki/pub/images/glyde.png
Sorry... for NOTHING *ollies*

Glyde is thinking of new slang for the word "cool," like "Freakadicious."


  • Attention Whore: Worse than Ice Cap, even. To Spare it, you have to deliberately deny it attention after giving it some.
  • Bonus Boss: Considering it's as much an Easter Egg as it is an actual enemy, defeating Glyde isn't acknowledged in any way besides the money you obtain.
  • Boss in Mook's Clothing: Doesn't have a unique battle theme and doesn't take that long to defeat, but it's effectively invincible, deals a lot more damage than anything else in the area, and is difficult to find on your own.
  • Eyes Do Not Belong There: Its "defeated" sprite reveals that the spot on its tail is a third eye.
  • Lady Not-Appearing-in-This-Game: Downplayed. The release trailer showcases a battle with Glyde, but unlike every other monster shown in the trailer, it's a Bonus Boss you actually have to go out of your way to find, and it's not easy to encounter even if you know hownote , on top of the fact that it can't be encountered after fighting Papyrus.
  • Metal Slime: Effectively. It only appears in a single room, and even then with a very low encounter rate (and only before you fight Papyrus on top of that), but is easily the most lucrative single enemy in the game to spare.
  • Totally Radical: It weaponizes this trope, thanks to its attack explosions turning into "cool" words.
  • Weapons-Grade Vocabulary: Its larger projectiles explode into words like "Nicey" and "Chill".

    Woshua 
https://static.tvtropes.org/pmwiki/pub/images/woshua.png
Wosh u face
Wosh u hand
Wosh u leg

This humble germophobe seeks to cleanse the whole world.


  • Almighty Janitor: Woshua becomes a literal example when his Golden Ending is achievednote .
  • Helpful Mook: Enforced. You have to get him to Clean you (that is, send an attack with two or three bullets healing you instead) to spare him.
  • Literal Metaphor: Mettaton's news ticker has a line that says Woshua cleans up crime by dousing criminals in soap and water. "Crime doesn't go down but it smells amazing."
  • Neat Freak: Extremely obsessed with cleanliness, to the point that letting him clean you is the main way to spare him. It even turns out that he regularly visits the trash dump just to clean the trash and organize it into identical piles.
  • Only Friend: Implied to (rather reluctantly) be this to Aaron.
  • Out, Damned Spot!: Randomly says this trope near-verbatim. ("out, darned spot!")
  • Police are Useless: He tries to clean up crime, according to one MTT news ticker... but all he does is make the criminals smell nice.
  • Punny Name: More like Wash-you-a, and likely based on the name Joshua.
  • Terrified of Germs: The reason why he tries to clean everything, and can only be spared if he cleans the player. If you hug Moldbygg (and get covered in slime), then try to touch Woshua, he will run away terrified.
  • True Companions: The bird is his best friend.
  • Try Not to Die: He advises the player to do this if you talk to him after going through Waterfall once, since he has to clean up the dust you make when you die. (Apparently, he doesn't realize that you're human or doesn't realize that humans don't instantly collapse into dust when they die.)
  • You Monster!: Will potentially call your SOUL unclean if you've killed anyone.

    Aaron 
https://static.tvtropes.org/pmwiki/pub/images/aaronstaticbattle.png
CHECK all you want! ;)

A large, muscular monster who is disliked by other monsters.


  • Character Development: After the event where he's scared by Napstablook's music, he will leave battles when shooed away. Before then, shooing him just causes him to say something creepy. note 
  • Character Tics: He's always winking, even when he's scared.
  • Emoticon: He uses these while talking (in every single sentence he says, to the point where they replace periods), possibly to heighten his obnoxiousness ;)
  • Expy: A muscular horse-based creature that prominently sweats? Sounds familiar, and given Toby Fox's past work, probably not coincidental.note 
  • Flexing Those Non-Biceps: Although his sprite doesn't change, flavor text says, "Aaron's muscles droop comically" when he's at low health.
  • The Friend Nobody Likes: He's disliked by most other monsters in Waterfall. Temmies will leave if he shows up, and Shyren flat-out avoids him. Woshua barely tolerates him.
  • Helpful Mook: Likely unintentionally. If encountered with Woshua, he'll turn the latter's bullets blue.
  • Ironic Hell: He considers the cavern being filled with spooky music to be this for being obnoxious. He also considers anime being real to be similar to his nightmares becoming true.
  • It's All About Me: Visit him after defeating/sparing Undyne but before entering New Home, and he will conclude that you're visiting Waterfall again just to see him flex.
  • The Missingno.: If a hacker tries to hack in one of the unfinished monster battles, any monsters who lack a "hurt" sprite upon being spared will use Aaron's as a placeholder.
  • Occult Detective: He becomes inspired into becoming a paranormal investigator if he gets spooked by Napstablook's songs.
  • Testosterone Poisoning: He's very muscular and loves to show himself off. You can spare him by flexing, which he then turns into a flex-off... and flexes himself right off the screen.

    Shyren 
https://static.tvtropes.org/pmwiki/pub/images/shyren_turned.png
se re, se re se mi se mi

Tone-deaf. She's too ashamed to sing her deadly song.


  • Actually Four Mooks: The monster you meet in combat is actually two entities. Shyren herself is only the 'head' of the monster and her 'body' is an un-named monster (in the files it's named "shyren_agent", suggesting that it's her talent agent). This is supported in the official Mettaton Live poster.
  • Flying Seafood Special: She 'swims' effortlessly in the air.
  • Friendship Song: If you continuously hum to her, you become very famous and good friends.
  • Increasingly Lethal Enemy: By humming to Shyren, you help her overcome her shyness and she'll become confident enough to sing. But this happens in a fight, and the more she sings, the more you have to dodge.
  • Portmanteau: Her name is a portmanteau of "shy" and "siren".
  • Shrinking Violet: She's exceedingly shy. The player can help her get over her insecurities by continuously humming to her.
  • Unique Enemy: There's only one encounter with her, but unlike a miniboss, she's no more difficult than your average random encounter. Despite this, three of them appear in New Home, all with agents, even!

    Moldbygg 
https://static.tvtropes.org/pmwiki/pub/images/moldbygg.PNG
*Chaste wiggle*

A Moldsmal with some odd lifestyle choices.


  • Blob Monster: Since it's another version of Moldsmal.
  • Hates Being Touched: You spare it through the 'Unhug' command.
  • Mind Screw: Wait, how exactly do you "unhug" something?!? You either hug it or you don't.
  • My Species Doth Protest Too Much: It's a Moldsmal that has strict personal boundaries, instead of sexily wiggling all the time.
  • Portmanteau: Like Moldsmal, its name is a portmanteau of "mold" and a misspelling of an adjective that describes size.
  • Spot the Thread: Moldbygg doesn't move while disguised as Moldsmal; a real Moldsmal jiggles. Additionally, Moldsmal can be spared immediately while Moldbygg can't.
  • Spread Shot: A bizarre inversion; it can do a reversed version of Moldsmal's exploding bullet, with eight bullets combining into one and flying upwards.
  • Underground Monkey: A more powerful Moldsmal. In fact, it appears to be a Moldsmal at first before erupting from the ground.

    Mad Dummy 
https://static.tvtropes.org/pmwiki/pub/images/mad_dummy.png
Futile.
Futile!
FUTILE!
Click here  to see the Nintendo Switch version's form.

A dummy that hates boring people.


  • Ambiguous Gender: A non-corporeal ghost (that was never a living person), only ever referred to as "them". Until becoming Mad Mew Mew, who is referred to as a girl.
  • Become a Real Boy: Wants to truly unite with their physical vessel, rather than merely possessing it. In the Pacifist route, becoming a real girl is still their goal. This time however, they're trying to become one with a life-sized Mew Mew Kissy Cutie doll, and realizes that they can't do so through extreme anger.
  • Belly Mouth: Instead of a stitched seam, they have a jaw of teeth below their midsection. Averted as Mad Mew Mew, since the doll has an actual mouth, though the dialogue box occasionally says a tinny, pre-recorded voice is coming out of a speaker in Mew Mew's chest.
  • Bonus Boss: Reappears in the Switch version as Mad Mew Mew, having stolen and possessed Alphys's life-sized Mew Mew Kissy Cutie figure.
  • Clingy Jealous Girl: Averted. After learning that Undyne and Alphys have already hooked up, she looks like they're going to go down this route, but instead decides that they'll respect their relationship and is glad that Undyne's happy.
  • Colour-Coded for Your Convenience: The battle in the Switch version gives three different colored orbs to avoid, based on the colors of the Nintendo Switch's Joycon controllers. Red and blue orbs can be dodged only by the corresponding-colored half of the player's SOUL, while white orbs have to be dodged altogether.
  • Combat Sadomasochist: As Mad Mew Mew, she makes it clear that - as Undyne's training dummy - she harbors a crush on Undyne and relishes the thought of getting stuck full of spears.
  • Comically Missing the Point: Mad Dummy "rescued" the Mew Mew Kissy Cutie doll from "a science-y place" after assuming that whoever owned it performed nasty experiments on it, apparently unaware of Alphys's Otaku nature.
  • Chekhov's Gunman: They're the cousin of the Training Dummy in the Ruins, and their reason for attacking you relates to how you handled the fight with them.
  • Despair Event Horizon: If the player survives long enough in the battle against Mew Mew, she'll sadly wonder what she's doing wrong, since she can't seem to fuse with anything. It's only then that a player can talk to them and calm them down.
  • Deadly Dodging: You can only hurt them with their own bullets, which come from other dummies that they summon.
  • Death by Irony: They spend the whole fight trying to kill you out of revenge for how you treated their cousin, sort of. In the No Mercy route, they're so furious at your terrible personality that the raw anger causes their spirit to bond with the dummy, making them corporeal and perfectly killable for the first time.
  • Death Glare: Implied by one message in between turns:
    Dialogue Box: Mad Dummy glares into a mirror, then turns to you with the same expression.
  • Disproportionate Retribution: Their reason for trying to attack you if you wasted time until the Training Dummy flew away? You're really boring, and boring people don't deserve to live.
  • Everyone Has Standards: Despite Mad Dummy being a Self-absorbed Jerkass as Mad Mew Mew she draws the line at interfering with Undyne and Alphys' relationship out of jealousy, instead vowing to respect their love and only wishes the best for Undyne.
  • Evil Laugh: When they realize that you can't harm them and they can't beat you, they laugh at the prospect of keeping you stuck in battle forever.
  • Foreshadowing: They try to do the same thing Sans does at the end of Genocide route: make their turn last forever so you can't have yours.
  • Ghostly Goals: To fuse with their current vessel so they can achieve a form along with using your SOUL to leave the Underground and try to find work as a shop window dummy. The battle with her as Mew Mew also reveals that she wants to become Undyne's training dummy again, just in a much cuter form. If spared, she makes additional plans to go into public performances and rival Mettaton.
  • Hair-Trigger Temper: No matter how you dealt with the Training Dummy, they will get angry regardless of your action. There's a pretty good reason why they're called the Mad Dummy.
  • It's All About Me: Their goal in trying to kill you? Leave the underground and get work as a dummy in a department-store window. (They also says they're trying to avenge their cousin, but can't even remember their name.) Even Mettaton is trying to save humanity while becoming a star.
  • Jerkass: They pretend they're attacking you to avenge their cousin, but that's just an excuse. Really, they just want the player character's soul for their own selfish ends. They never show remorse for it, either. Even on Genocide, they're immediately okay with you and let you go once they gets what they wanted, and their supposed rage at your murderous actions disappears completely.
  • Jerkass Realization:
    • In the True Pacifist ending, they're grateful that the monsters are free and finally admit they acted like a dummy.
  • Knife Nut: Once they get tired of getting Hoist by His Own Petard, they will try to throw knives at you. They only have one, though.
    Mad Dummy: I DON'T NEED FRIENDS!!! I'VE GOT KNIVES!!!
    Mad Dummy: I'M... Out of knives.
  • Large Ham: Between their furious yelling and Verbal Tic, Mad Dummy is definitely one of the more over-the-top monsters in the Underground.
  • Laughing Mad: Naturally. They truly break into this after their last attack, cackling loudly to the point that their separate pieces start to fly apart out of a combination of anger and borderline craziness.
  • Leaning on the Fourth Wall: In the Switch version, she uses a new SOUL mode based on the Nintendo Switch Joy-Cons.
  • Leitmotif: "Dummy!", a remix of "Ghost Fight". Her theme as Mad Mew Mew is also a remix of the same song.
  • Mathematician's Answer: The 1.001 update changes their CHECK description so that, instead of a numerical value, their defense is simply listed as "YES".
  • Mean Boss: To say that they're upset at their mini-dummies for accidentally shooting them is putting it lightly. They fire all of them mid-battle because they're sick of getting shot by them.
  • Mecha-Mooks: They will eventually dismiss the regular bullet dummies for hitting them instead of you, causing them to replace them with robotic dummies that fire homing projectiles instead (they're not much better, though).
  • Mini-Boss: Has more pomp and circumstance than a regular enemy, but doesn't have an effect on the overall plot.
  • Misguided Missile: In their second phase, the missiles their dummies fire must be redirected so they can hit the Mad Dummy. These missiles stop tracking you after a few seconds and continue flying off; this is required to hit them because the missiles usually don't leave the range of your SOUL's movement.
  • Musical Spoiler: If her name didn't tip you off, Mad Mew Mew's boss theme is another remix of Ghost Fight with the more aggressive tones of Dummy!, giving away that she's Mad Dummy.
  • Nigh-Invulnerability: Being a ghost possessing a dummy, they are immune to physical attacks. Subverted in a No Mercy run, where they manage to become one with the dummy through sheer anger, thus making them corporeal enough to hit.
  • No-Sell: Hit them with your own attack and they'll just rebuild itself, no worse for wear.
  • Off with His Head!:
    • If attacked, they'll smash into pieces (head included), and then just reform back together since they haven't actually fused with the training dummy yet. Attacking her as Mew Mew causes her head to fly off. However, because she's still Nigh Invulnerable as a ghost, the attack doesn't do any damage, and she just puts her head right back on.
  • The Power of Hate: The dummy believes they can Become a Real Boy if they become angry enough. This only works in a Genocide run, as every other time, the Dummy can't get angry enough to fuse with their vessel.
  • Puzzle Boss: They're immune to physical attacks (since they're a ghost) and refuse to back down and let you spare them. The only way to progress is to trick them into using their own magic projectiles against them.
  • Rule of Three: They tend to repeat their words three times before they make any progress. This even drips into their song (a remix of Napstablook's theme) which constantly repeats chords three times before continuing on with the song.
  • Screw This, I'm Outta Here!:
    • Finally decides they've had enough when Napstablook cries their magic tears on them.
    • In a No Mercy run, the Glad Dummy will make the same kind of exit as the standard Dummy if you fool around too much. This is one of the less obvious ways to cancel a No Mercy run without resetting.
  • Shout-Out:
    • It's pretty much the only monster in the Underground without a shred of decency: they're immortal, they throw knives as a desperation attack, and they frequently shout one word or phrase three times in a row that either directly means or is a synonym of "useless". MUDA MUDA MUDAAA!
  • Suddenly SHOUTING!: Their speech pattern goes normally voiced, louder, and finally ALL IN CAPS.
  • Surrounded by Idiots: Their mini-dummies that shoot magic attacks. After they take too many of them, they get angry(er) and fire them in a huff.
  • Tactical Suicide Boss: Their attacks are the only reason they can be hurt. To their credit, they realize this and change up their attacks twice in an attempt to avert it. However, all of their good attacks are the ones they can be hurt by; the one that can't hurt them (the knife) only has one shot, and the battle ends after they throw the knife.
  • Transgender: Mad Mew Mew is implied to be Agender to Female through her usage of she/her pronouns after taking on her new body and her dialogue absolutely dripping with Transgender sentiments.
  • Verbal Tic: Repeating themselves three times, each getting progressively louder, is their Verbal Tic. Even referenced in their battle theme where certain lines play three times before carrying on with the rest of the song.
  • Victory by Endurance: The only way to win in the battles with them, including the Switch version, is to survive long enough. In the Mad Dummy battle, Napstablook's tears drive the Dummy away. As Mew Mew, she hits a Despair Event Horizon after her second attempt at fusion fails, allowing the player to talk to her.
  • We Will Meet Again: If the player kills her as Mad Mew Mew, she'll vow revenge against the human in the future before her broken, busted body flies offscreen. Somehow.
  • Wins by Doing Absolutely Nothing: At the end of the fight, they try to do this to you. Since you can't hurt them (directly) and they can't hurt you (anymore), they decide that the only way to keep fighting you is to refuse to end their turn, keeping you trapped "forever." It fails miserably when Napstablook starts damaging them with their tears.

    Vulkin 
https://static.tvtropes.org/pmwiki/pub/images/vulkin.png
Ah! I'll help! Healing magmas!

Mistakenly believes its lava can heal people.


  • Betty and Veronica: As a joke, when fighting a Tsunderplane and a Vulkin, they will be introduced like this.
  • Helpful Mook: An inversion of the "accidentally-assisting" type. It wants to help you, but isn't particularly effective at it...
  • Magma Man: It believes that its lava can heal people (it can't).
  • Mundane Utility: It can be seen next to Sans's hot dog stand using its magma to heat up a hot dog.
    "Toasty bun!"
  • Punny Name: "Vulcan" (god of the forge) or "Volcano" with "kin".
  • Shock and Awe: It has an attack where it summons a smiling cloud to rain down lightning bolts on you. This is because of a possible Genius Bonus: Any particlate cloud of sufficient size can create lightning, due to charge built up in the cloud. This includes ash clouds from volcanoes, which tend to be called 'dirty lightning'.
  • Unwanted Assistance: In-Universe. It's a kind monster and wants to help you, but it doesn't realize its attacks hurt you.
  • Video Game Caring Potential: Two of the three ways to spare it are to encourage it (making its attacks harder to dodge) or hug it (reducing your defense). Alternatively...
  • Video Game Cruelty Potential: You can tell it that its attacks aren't helpful at all, lessening its attack, but leaving the poor thing heartbroken, and if you do it again, it runs away crying.

    Tsunderplane 
https://static.tvtropes.org/pmwiki/pub/images/tsunderplanebattlestatic.png
It's not like I LIKE you.

Seems mean, but does it secretly like you?


  • Anguished Declaration of Love: It can be coaxed into blurting out its feelings in the midst of battle.
  • Clingy Jealous Girl: If paired up with a Vulkin during battle:
    Tsunderplane attacks! Not because it's jealous Vulkin is paying attention to you!
  • Death from Above: One of its attacks is to send planes that drop firebombs at you.
  • Defeat Equals Explosion: It's unique among monsters in that it will explode instead of fading away.
  • Incredible Shrinking Man: When spared, Tsunderplane will become tiny in the upper right corner of the screen. Vulkin insists it does this all the time.
  • In Love with Love: Tsunderplane claims to have this in the epilogue to excuse its earlier attempts to get closer to you.
  • Killed Mid-Sentence: If the player kills Tsunderplane, it will let out an anguished cry before it explodes.
    "B-but I never got to...!" (kaboom!)
  • Late for School: In a parody of a common anime romance trope, the epilogue mentions at some point it was late flying to school and bumped into someone while having toast in its mouth.
  • Made of Explodium: One of the few monsters that doesn't turn to dust upon death on-screen. It instead spirals out of control, crashes, and explodes.
  • Master of the Mixed Message: A news ticker in a Mettaton section says that it gave a cashier hours of confusion by telling him it "didn't want to buy these products or anything."
  • Punny Name: Tsund-Airplane. Its name is also a near-homophone of Cinder-Plane.
  • Sentient Vehicle: A sentient Tsundere airplane.
  • Size Shifter: Able to appear as large as a real-life Airbus plane when it wants to.
  • Tsundere: The Tsunderplane is a tsundere airplane that apparently has a crush on you. If you find it later after the barrier's been destroyed, it admits in a lengthy, probably rehearsed speech that it was only in love with the concept of romance, although the yellow credits suggest that it's still in denial.
  • Weaponized Exhaust: It can push its exhaust clouds horizontally.

    Pyrope 
https://static.tvtropes.org/pmwiki/pub/images/pyropebattlestatic.png
Hot enough for ya!?

This mischievous monster is never warm enough.


  • Cartoon Bomb: Drops them in one of its attacks. They even explode into a cartoon "BOOM".
  • The Dividual: If two appear at once, they are called "The rare and threatening Double Davis."
  • Fire of Comfort: You can turn up the temperature to make Pyrope happy at the cost of making their attacks more powerful. Oddly enough, this applies to the player as well, since his fire is completely harmless as long as the player's soul keeps moving.
  • Having a Blast: As well as using them in one of its attacks, one of the items in Mettaton's news ticker says it would've loved the bomb scenario that the player is in.
  • Interface Screw: Should you turn the heat up, the screen wiggles in a heat haze. This gets worse the more you turn the heat up.
  • Meaningful Name: Pyro + Rope = Pyrope. Not to be confused with Terezi Pyrope, or the gemstone pyrope (the name was most likely taken from the former, due to Toby Fox's work on Homestuck).
  • Stealth Pun: Rope burns occur when a rope runs across your skin quickly, causing great friction, and thus have nothing to do with fire. Pyrope, however, is literally a burning rope. It can be subverted, though, since some of the flavor text makes the pun more explicit ("Smells like rope burn").
  • Violation of Common Sense: The only way to avoid his attacks is to aim your soul through the fire instead of avoiding it.

    Royal Guards 
https://static.tvtropes.org/pmwiki/pub/images/royal.png
Like, team attack!

... team attack.

Guards. Royal ones.


  • 24-Hour Armor: Except for when 02 takes off his breastplate because of the heat, they are never seen without their armor.
  • Big Damn Heroes: If you spare them, they both become this to the Nice Cream Guy as they buy out his entire stock, persuading him to stay in business.
  • Black Knight: In appearance thanks to their glossy dark armor, large swords, and face-concealing helmets. Ultimately, however, 01 is a loud frat boy and 02 is his shy wallflower friend.
  • Despair Event Horizon: In contrast with 02, if only 01 is left alive, his reaction basically goes from swearing vengeance, to anguish, to despair.
  • Everyone Calls Him "Barkeep": They're only referred to as "01" and "02," even when speaking to each other!
  • Fratbro: 01's characterization, being mostly this with a dash of Surfer Dude thanks to his constant use of the words 'like' and 'bro.'
  • Getting Hot in Here: The Royal Guards are located in Hotland, and use cooling dirt to keep their suits of armor cool. Washing it off causes one of them to get overheated, so he takes it off. It also gets the other guard overheated and too distracted to fight, but in a different way.
  • The Guards Must Be Crazy: Literally. When you first meet them in Hotland, both warn you about a dangerous human Undyne warned them about and put a kill-on-sight order on them, and the reason why they try to catch you the second time on a neutral run? They're evacuating the area and try to bring you to safety. RG 02 picks up on this, however.
  • "Just Joking" Justification: When 01 confesses his love to 02, and it momentarily looks like that the latter doesn't reciprocate, the former backpedals and claims it was a joke. 02 does reciprocate, however.
  • Like Is, Like, a Comma: 01 has a habit of saying "like" when it isn't necessary.
  • Manly Gay: If 01's interactions with 02 say anything. Humorously, Undyne of all people seems to be completely oblivious to it if you call her in the area they're fought, referring to their "platonic friendship."
  • Mini-Boss: You need to fight them to move forward and their battle is unique, but they're secondary characters and beating them isn't particularly hard.
  • Petting Zoo People: It's pretty hard to tell at first glance, especially since they're wearing all-encompassing armor, but 01 has rabbit ears and 02 has draconic fins on the sides of his head and his chest is covered in scales. If you call Undyne standing in the area where you fight them, she confirms them as a rabbit and a dragon.
  • The Quiet One: 02, who just mumbles things and sighs where 01 is shouty and enthusiastic.
  • Red Oni, Blue Oni: 01 is red, 02 is blue.
  • Roaring Rampage of Revenge: Killing one of them results in the other's attacks becoming much more fierce, though 02 seems more angry in the flavor text and 01 just seems to be in despair.
  • Shirtless Scene: 02 gets very hot and sweaty during your fight and decides to take off the top of his armor. This makes 01 very nervous.
  • Those Two Guys: Mostly interchangeable? Check. Completely inseparable? Check.
  • Together in Death: If they are killed. Checking them in No Mercy nets this dialogue: "I see two lovers staring over the edge of the cauldron of hell. Do they both wish for death? That means their love will end in hell. I couldn't stop laughing."
  • Tranquil Fury: If you kill 01, 02 is implied to have this, as he doesn't say much but the flavor text paints him as furious at you.
  • Video Game Cruelty Potential: You can kill them after you get them to admit their feelings for each other.
  • What the Hell, Hero?: Killing 02 when they can be spared gets 01 to ask you why you had to do that.
  • You Are Number 6: Their names really are 01 and 02.

    So Sorry 
https://static.tvtropes.org/pmwiki/pub/images/so_sorry.PNG
Ahhhh!!! I'm late!!! I'm late!!! I'm so sorry!!!

This creature is definitely in the wrong time and space!


  • Adorkable: A clumsy, nervous, constantly-apologizing artist that's constantly Shy Finger-Twiddling, and is a cute, chubby, floppy-eared dragon wearing a vest and a bowler hat.
  • Apologetic Attacker: He's not even trying to attack you; his "attacks" are just being generally clumsy in his attempts to draw you a picture, with a tail strike or tossing paper around. As if his name wasn't a more obvious indication.
  • Apologises a Lot: It's in his name!
  • Art Initiates Life: He's an artist with a magic pencil, but accidentally draws some monsters that come to life in an attempt to draw a picture of you.
  • Author Avatar: Of one of the Kickstarter backers.
  • Bleached Underpants: Outside of Undertale, he appears in a lot of fat-fetish art. There's zero indication of this in his appearance here. We're not judging, though; like Sans says, people who like hot animals keep people like Toby in business.
  • Bonus Boss: So Sorry (yes, that's their name) is very obscure to find. There's a hidden path in Hotland near Sans's hot dog stand. The encounter still doesn't trigger unless all of the elevator stops are available and the internal clock is set to October 10, 8:00pm.
  • Breaking the Fourth Wall: Reduce his health to a certain amount and he'll try to persuade you not to kill him because he doesn't even give out enough EXP to level you up at level 1. He's right. He only gives one EXP.
  • The Cameo: One of several characters added to the game by a Kickstarter backer.
  • Fixed Damage Attack: Inverted. All your attacks do exactly 1/11 of his HP.
  • Flunky Boss: He'll accidentally summon a few crudely drawn monsters partway through the fight, though they can be sent away easily.
  • Guide Dang It!: Reaching So Sorry requires having your computer's time set to a very specific setting and going through the secret path that opens up in a specific place. It is very unlikely to have this happen by accident.
  • His Name Really Is "Barkeep": One of the first things he says when encountering the player is "I'm so sorry!" He is So Sorry.
  • Holiday Mode: Fighting him at all also requires a specific date and time.
  • Leitmotif: "Wrong Enemy !?"
  • Motor Mouth: Noticeably during the fight, his text prints much faster than any other character in the game.
  • Mundanger: See Apologetic Attacker above.
  • Only Known By His Nickname: He does have a real name, being a preexisting character, but that information isn't anywhere in the game. This might be to avoid family-unfriendly Google associations.

    Final Froggit 
https://static.tvtropes.org/pmwiki/pub/images/final_froggitbattlestatic.png
Robbit, robbit.

Its future looks brighter and brighter.


  • Combat Compliment: It will be impressed if you stand up to Astigmatism.
  • Eyes Do Not Belong There: Overlaps with Wingding Eyes; Much like its lesser cousin, Final Froggit has eyes on its underbelly.
  • Hard Mode Perks: Will appear in the Ruins on Hard mode.
  • Hired Guns: Mettaton hires some to attack you in the CORE.
  • Ironic Echo: Most of its lines are dramatic inversions of lines that concerned Froggit.
    "Final Froggit knows exactly why it's here."
  • Seen It All: It has this attitude when you fight it. You spare it by mystifying it and show that there's much left in this world to see.
  • Shell-Shocked Veteran: If its flavor text of the battlefield being filled with the smell of mustard seed is any indication.
  • Underground Monkey: A more powerful version of Froggit.
  • Wall Jump: Its frog "bullet" that it attacks you with can jump again after hitting a wall.

    Whimsalot 
https://static.tvtropes.org/pmwiki/pub/images/whimsalot.png
Not this time.

A guilty mercenary monster.


  • Despair Event Horizon: They lost their conscience because they view life as having no hope.
  • Driven to Suicide: Its check text reads “smells like nightshade and bleach”, both of which are used in suicide attempts.
    • Notably, its lines tend to have a resigned feeling to them. "I've made my choice. I've made my peace." And you spare them by praying for safety — but for who? You, or them? Perhaps their spare is a compression of talking them out of suicide?
  • Face Framed in Shadow: Removing its mask reveals its face to be mostly hidden.
  • Glass Cannon: Has a high amount of attack, but the lowest defense of any Core monster. Before the January update, it was a negative value.
  • Hard Mode Perks: Will appear in the Ruins on Hard mode.
  • Hired Guns: Mettaton hires some to attack you in the CORE.
  • My God, What Have I Done?: You can spare it if you manage to make it "remember its conscience".
  • Underground Monkey: A more powerful version of Whimsun. Notably, it actually has the emotional fortitude to attack properly.

    Astigmatism 
https://static.tvtropes.org/pmwiki/pub/images/astigmatismbattlestatic.png
Pick on me.

This manipulative bully ALWAYS gets what it wants.


  • Hard Mode Perks: Appears in the Ruins on Hard mode.
  • Hired Guns: Mettaton hires some to attack you in the CORE.
  • Manipulative Bastard: To spare them, you have to do whatever they say. In the credits, this enemy becomes a "domineering glasses salesman".
  • Oculothorax: A walking eye-monster, just like Loox, although occasionally it will close its eye, form teeth on it to make it look like a grinning mouth, and gain another set of eyes on the vertical lines above its main eye.
  • Underground Monkey: A more powerful version of Loox.

    Madjick 
https://static.tvtropes.org/pmwiki/pub/images/madjick.png
Please and thank you.

A mercenary monster that uses magic.


  • Armless Biped: What looks like two floating hands are actually two magic orbs.
  • Death Glare: You can glare at the orbs to weaken them. Staring at them twice incapacitates them.
  • Dressing as the Enemy: Wielding the Stick against him will trick him into thinking that you're a wizard like him.
  • Energy Ball: Two of these float around it during the fight. You have to stare them into submission to spare it. One of its attacks also involves three orbs chasing you, which can phase through the box and teleport to the other side.
  • Eye-Obscuring Hat: Its eyes are covered by its wizard hat.
  • Hired Guns: Just like Knight Knight, Astigmatism, Final Froggit, and Whimsalot.
  • Interface Screw: It can reverse your controls, which can be stopped by clearing your mind.
  • Magical Incantation: Spouts these during their fight. It includes the classic 'Hocus Pocus' alongside 'Please and thank you'.
  • Mundane Utility: In the True Ending, it can use its magic to become a better bowler.
  • Punny Name: Mad Jick = Magic.
  • Shout-Out: One of its magic words goes, "Tinkle Tinkle Hoy!", a reference to Oyasumi Punpun, in which "tinkle tinkle hoy" are the magic words used to summon a god.
  • Sword and Sorcerer: Often appears alongside Knight Knight.
  • Troll: It can be satisfied into being spared by letting it interrupt you when you try to talk to it.

    Knight Knight 
https://static.tvtropes.org/pmwiki/pub/images/knight_knight.png
Adieu.

This megaton mercenary wields the Good Morningstar.


  • Boss in Mook Clothing: While not as proportionately powerful to the player upon encounter as Glyde, she does have the most health of any non-boss monster in the game, and she takes several turns to spare (only two if the player previously hummed to Shyren). Her attacks are also very elaborate for a non-boss enemy.
  • Cyclops: Appears to have one giant, single eye.
  • Eyes Do Not Belong There: She has an extra set of eyes and a beak on her abdomen.
  • Hired Guns: Just like Madjick, Astigmatism, Final Froggit, and Whimsalot.
  • Magic Knight: She uses a mace as well as sun and moon spells.
  • Painting the Medium: She is unique among monsters in that she does not have text boxes and instead has large, free-floating white text.
  • Pre-Mortem One-Liner: Most of her lines are permutations of "Goodnight/goodbye".
  • Punny Name: You have the option to sing Knight Knight to sleep. Nighty-night! Also, her weapon is the Good Morningstar.
  • The Quiet One: She only speaks in single short sentences. Even when appearing in New Home to tell the monsters' story, Madjick is the one to tell most of their segment.
  • Samus Is a Girl: You wouldn't be able to determine her gender if it weren't for the flavor text describing her swinging her weapon around.
  • Solar and Lunar: She has an attack where she summons a Sun which fires bullets, or a Moon which causes a hail of bullets.
  • Sword and Sorcerer: Often appears alongside Madjick.

Hisssss
Hersssss

This cobrafied carrot has a headful of tasty snakes.


  • Anthropomorphic Food: It's still a vegetable, albeit only in the loosest sense.
  • Eat the Dog: Bizarrely, this is still an option. (The protagonist will slurp the snakes up like spaghetti.)
  • Edible Ammunition: Similar to asking Vegetoid for "Dinner", you can ask it for "Snacks"... which it will mishear as "Snakes." You can still eat the green one, though.
  • Hard Mode Perks: Only appears on Hard mode.
  • Helpful Mook: Enforced. Asking it for "Snacks" works exactly the same as asking Vegetoid for "Dinner".
  • Medusa: Has snakes for "hair" instead of leaves, anyway.
  • Nightmare Face: Its visage is intimidating, to say the least.
  • Punny Name: "Parsnip" with the suggestion of the word "snake".
  • Sssssnaketalk: A few of its lines are this, as seen in the quote above.
  • Underground Monkey: A more powerful version of Vegetoid.

    Moldessa

(slime sounds)

Can't decide on a face.


  • Blob Monster: Notably more humanoid than the other blob-shaped monsters.
  • Hard Mode Perks: Only appears on Hard mode.
  • Helpful Mook: If Moldessa appears with other monsters, the "Lie Down" ACT will make them all spareable.
  • Underground Monkey: Another variant on Moldsmal.
  • Wingding Eyes: Takes this trope to the logical extreme with an entire Wingding Face. Since its facial features are constantly shifting around, you have to help it settle on a face to spare it.

Honk. HOOONK!

This messed-up clownbug thinks battle's a performance.


  • Big Creepy-Crawlies: Like Migosp, it's a large insect that can summon bugs in its attacks.
  • Hard Mode Perks: Only appears on Hard mode.
  • Monster Clown: Literally a monster who also happens to be a clown. It drops the goofy facade if it's the only monster remaining in battle.
  • Sad Clown: It pretends to be happy in the presence of other monsters, but as soon as they leave, they show their sadness. Apparently, it laughs to hide its pain.
  • Underground Monkey: A more powerful version of Migosp.
