Underfell

Underfell is an AU of the well-known role-playing video game Undertale where all of the good-natured monsters who don't actually want to hurt the protagonist, are replaced by vicious versions with opposite intentions and vice versa. One prime example of this is Flowey, who, normally shown as being an antagonist in Undertale, actually wants to help the protagonist escape the Underground safely.FAQ Underfell blog It presents a universe where the Underground monsters are darker versions of their originals. Some fans refer to these characters with 'Nega' but must refer the characters as 'Fell' as a prefix to differentiate from canon.
There are many interpretations of this universe, but most share similarities such as Frisk falling from Mt. Ebott and meeting Flowey, who isn't evil but rather a guide through the Ruins, and instead, King Asgore is the one that has instated the motto "Kill or be killed" and the one who poisoned Chara rather than themselves. 
Underfell was foremost created as a design aesthetic, so there originally wasn't a canon backstory to the characters outside of the idea that they are an alternative, evil version of the regular Undertale canon characters. However, there are some various ideas about the characters that are widely accepted, such as Sans getting easily flustered and irritated by flirting, puns, and having an obsession with mustard or Papyrus being a cold individual with no patience for failure (especially not from his brother). Later on when the creator of Underfell returned actual canon personalities got created.
All of the monsters are essentially malicious/more violent than in Undertale. They attack one another and don't all appreciate the fact that Frisk is befriending them. Instead of promising to protect the human, Sans is dared to kill them. Instead of the wide arrange or friendly colors, most characters tend to share a fashion of black, red, and gold, with red also being the color often used for battle sprites. Flowey and Mad (Sad) Dummy are pretty much the nicest characters/only nice characters (and some of the only monsters without black, red and/or gold in their character design). Monsters weren't always this way however, their evil nature is caused by the downward spiral the Underground got into.https://underfell.tumblr.com/post/185264510156/what-is-gaster-like-in-this-au-if-you-dont-mind
Even though the creator returned to the community, the AU still remains community-shared howeverhttps://underfell.tumblr.com/post/618197110014328832/what-are-your-thoughts-on-rynoggs-take-on as they have gone on to continuously state they are in full support of all non-problematic takes and interpretations,https://underfell.tumblr.com/post/184113502076/seeing-as-this-blog-is-hopefully-v-becoming very much enjoying them and asking fans not to send hate to AU takes and designs just for going outside Fella's personal interpretations.https://underfell.tumblr.com/post/184113967516/also
== Characters ==
=== Frisk ===
Frisk, together with Flowey, is a Pacifist-Run character in a world of Genocide-Run based monsters, trying to befriend the characters who are trying to kill them and refusing to stop trying to make everyone like them. While in most depictions of this AU they can be seen wearing a black shirt with a red stripe, they canonically wear a blue shirt with pink and black stripes. 
Frisk is a tired kid who doesn’t put up with nonsense sometimes. No matter how many times the monsters try to break Frisk, with the help of Flowey, they never really get to that point (with the exception in the Genocide Route). Their actions are humorous a lot more than the words they say. Frisk is very absent minded, but they accidentally display how they feel with the mannerisms they show in general.Bio on Frisk
=== Flowey ===
Flowey is Frisk's companion. It is confirmed that Flowey likes singing, but sometimes he gets carried away and gets too loud at the worst times.https://underfell.tumblr.com/post/618529107145375744/does-flowey-like-singing Flowey fears every other monster. Even though he’s been beat to the ground and nearing death, he’s always optimistic as he cheers Frisk on. There's also probably a box cutter in his pot.Bio on Flowey
=== Toriel ===
Toriel makes meat pies instead of baking due to being bad at it.https://underfell.tumblr.com/post/162622843291/whats-the-info-on-uftoriel-o-theres-so-much Before her children died, she cared for her family but was afraid of Asgore's hatred of humans so she took care of Chara with her husband's knowledge when she found out that Asgore poisoned Chara, she ran away to the Ruins where she lost her sanity. Toriel also has a very colorful rose garden, never manages to NOT get her top torn apart from going in to water/cut them. Toriel only does direct eye contact when you interact with her and never looks anywhere else unless you look away. Toriel was also the one who made Asgore's cape.Bio on Toriel
=== Napstablook ===
Napstablook loathes anyone who is affiliated with Alphys and Asgore. They tend to giggle a lot. Napstablook also has enough confidence to tell you the truth or their opinions. They take "fake it til you make it" too far when it comes to expressing their emotions. Napstablook is not jittery, he is just very, very, awkward and will awkwardly laugh through awkward silences. They aren't evil, but are just very passive about Frisk and doesn’t believe they’ll make it out of the underground alive.Info about NapstablookMore Info about Napstablook
=== Sans ===
Sans strives to be the cool and collect brother of Papyrus. Sans can also be sarcastic as well. Sans calls Papyrus any variation of the word boss but in a very stupid way.https://underfell.tumblr.com/post/185334214951/if-were-gonna-say-sans-refers-to-papyrus Instead of saying "You're gonna have a bad time", Fell!Sans instead says "I'm going to have ONE HELL OF A TIME!!!".https://underfell.tumblr.com/post/185949100506/i-needed-to-get-this-out-before-my-hand-fully He makes and sells chimichangas rather than hotdogs.https://underfell.tumblr.com/post/685059433571794944/what-did-underfell-sans-sells-instead-of-hot-dogs Sans got his jacket from Grillby when he actually got him to laugh, even though it was unintentional. https://underfell.tumblr.com/post/187195149586/did-sans-get-grillby-to-laughsmile-and-earned-his
Sans's red eye shows to reflect how “corrupt” (mainly emotionally hopeless) he’s gotten, so when it flickers, it would be yellow and orange.https://underfell.tumblr.com/post/189812801461/does-sanss-eye-turn-the-classic-colors-when Sans plays the trumpet instead of a trombone.What does Sans play in Underfell? Sans holds in a lot of emotional stress, so he’s constantly radiating his powers, which mostly affects his jacket fur. Sans is technically one of the most powerful monsters, but with the consequence of hurting himself the most.Bio about Sans
=== Papyrus ===
Instead of spaghetti, Papyrus will cook lasagna, and instead of laughing "Nyeh heh heh," Papyrus doesn’t really laugh. Instead, he snorts or says “MWAH HAW HAW HAW”. He also “hmph”s as well.https://underfell.tumblr.com/post/189806916921/its-ya-boyzzzz-revamped-redone-finalized-funhttps://underfell.tumblr.com/post/187807885116/oh-man-it-took-me-ages-to-finally-realize-it-for He is also a great cook, therefore his lasagna is very good. Papyrus would try to kill frisk with a many layered cheese lasagna that is both delicious and gruesomely bad for them.https://underfell.tumblr.com/post/187295395936/is-papyrus-liking-lasagna-canon-in-the-uf-au-or Papyrus actually is one of the monsters who would have any remorse of killing someone.Papyrus has remorse Papyrus also has a huge responsibility being in the royal guard, in which he takes very seriously, especially considering that he's only in it to protect his own brother. He presents himself like him killing is for “sport” to be menacing so he could be on everyone else’s good side. However, this doesn't mean he actually likes doing it. He knows that the huge weight he carries isn’t from his armor, but from his guilt.
He also loves evil puns. However, if you tell him a joke that isn’t evil, he will not understand it. Papyrus also tries to be the cool and collect brother. He’s actually almost matched with Undyne’s strength. He also gloats a lot, for absolutely no reason. If he’s being decent, he would do some humble bragging. Papyrus can be obliviously considerate at times and can be awkwardly supportive.
Absolutely no one knows how he has so much leg. His boots were given to him from Alphys, which makes him even more insanely tall. He’s presumably the third tallest of the main monsters. His wrestle mania belt was given to him by Undyne after he beat her in sparring.
Sans and Papyrus's relationship does have some fighting, but not in a very violent way.https://underfell.tumblr.com/post/184182369551/since-this-blog-is-starting-to-take-back-traction Papyrus is not abusive towards Sans. Instead, he cares for Sans a lot. He actually wants to help him but Sans continuously makes excuses not to accept it which annoys him.https://underfell.tumblr.com/post/189829211671More stuff about Papyrus The only reason he even joined the royal guard was to protect Sans from Asgore.
=== Grillby ===
Grillby is green with purple hues within while working, and purple when he is off work. He’s not mean, he just doesn’t care about what goes on and will show he doesn’t. Grillby is also more stoic and serious. However, if you can crack a chuckle out of him, he’ll give you a smaller version of his own jacket.Example of what happens if you make Grillby chuckle Sans actually pays Grillby in socks, even though it does get on Grillby's nerves from time to time, he still accepts it to pay Sans’s tab. He also always wears those socks too.Info about Grillby
=== Undyne and Alphys ===
Undyne and Alphys are already in the process of dating by the time of the human's arrival.https://underfell.tumblr.com/post/184204703166/can-you-believe-it-fun-facts-under-read 
Alphys is very confident monster who never second guesses her own decisions. She is also arrogant, almost as much as Asgore. Alphys conducts terrible experiments on everyone (mainly fashion for the main cast). If the intro to the anime is on par with Nyan Cat, she would play the Mew Mew Kissy Cutie intro for 24 hours, with no breaks. 
Undyne actually gave Alphys her glasses because Undyne saw an anime. Alphys doesn’t really have sympathy or empathy for others outside her circle. She also has an adorable laugh you wouldn’t expect if you actually managed to make her laugh.Info about Alphys
Undyne is the captain of the Royal Guard. She loves sparring with Papyrus, but doesn’t admit it. She has lost to Papyrus once and gave him a wrestle mania belt. Undyne is insanely fast, insanely strong, and is the strongest in combat. Her matte lipstick was given to her by Alphys. Undyne doesn’t get angry easily and doesn’t get in a fight immediately either. However, whenever she does get into a fight/battle, she will never let down. Undyne is also merciless, almost as much as Asgore.Info about Undyne
=== Mettaton ===
Mettaton is often seen having four arms in his box form, but canonically he only has two arms in his box form. Mettaton is still famous and beloved by the majority of the monsters. Instead of acting like a genocidal robot, he acts like your good friend, but later attempts to betray you. Mettaton also shows disgust very plainly, he sometimes shows it when he tries to “befriend” you. He is hilariously dramatic, swoons, and has blush taped on his front. He also says "teehee". 
Unlike original Mettaton, Underfell Mettaton, in fact, hates how he looks and is very disappointed of it. Alphys has forcefully programmed him to have confidence in his looks. However, the malfunctions he occasionally has in him gets him out of the forced program. Mettaton's yellow gloves are actually one of the limbs he has no full control of, as those arms are only controllable by Alphys. Whatever you do, don’t stare at him too long. If you do, things will get dark fast.https://underfell.tumblr.com/post/185398325246/the-man-the-myth-the-legend-mettaton-instead He always has a smile on his face.Info about Mettaton
=== Muffet ===
Muffet is often depicted wearing red and black clothes, however she actually wears black and purple clothes. Muffet's extra two limbs (the black ones that have three claws) are actually robotic limbs that were given from Alphys. She is is the richest of all the monsters in the underground, even being richer than Asgore. She likes to flex on any monster in existence, especially Asgore and Sans. Muffet is also a jewelry fanatic. If you find a rare stone for her maybe she’ll have an opening for you to talk to her. She likes tea great, but she also likes coffee that has non-dairy alternatives (she never takes black coffee). Her pastries are delicious but there might be venom in them. However, if you mess with with any of her spiders, you're dead.Info about Muffet
=== Burgerpants ===
Burgerpants absolutely hates his job and doesn't even care about it. You could steal everything in the store and all he’d say is “Oh nooo, don’t do that” while his eyes are glued to a magazine. 
He only cares about your presence as a customer if you leave him a pretty generous tip. However, If you steal the tip jar, he will murder you.Trivia about Burgerpants
=== Asgore ===
Asgore is the tallest and cruelest character in Underfell (by far). He’s doesn't only collect human souls, but also collects monster souls as well. He treasures his garden so greatly that if you decide to ruin so much as a leaf in it, he will kill you instantly. Asgore’s boots help improve his agility as well. Asgore is also entirely apathetic towards everyone. However, even if he almost always never shows it, he still holds a soft spot for Toriel. He will rarely have a moment of uncertainty. Asgore will have a cup of herbal tea at his garden, contemplating whether or not he will ever be forgiven for what he's doing.Info about Asgore 
Asgore poisoned Chara because he thinks that all humans are evil.Why did Asgore poison Chara He is also the one responsible for making Papyrus's scar and why Sans has uncontrollable powers.Evidence that Asgore is responsible for what happened to the skelebros There was also a time where Asgore wanted to crush Sans's head for insulting him.Asgore has tried to kill Sans 
=== Asriel ===
Asriel is very similar to his Undertale counterpart, but is more rude (accidentally) and is mildly arrogant. He is also normally confused, yet will understand if convinced. At first, he distanced himself from Chara until seeing how kind they were to him. 
He still goes to the surface, but for different reasons. He place Chara on the flowers at their home after being poisoned by Asgore. However, Asriel still meets the same fate as his Undertale counterpart.[https://underfell.tumblr.com/post/187301427306/cant-draw-on-cpu-yet-so-heres-a-brief Info about Asriel and Chara
=== Chara ===
Chara is very sweet and considerate child who puts monsters before themselves. They don't like or hate humanity since they knew what the humans did was wrong, but is hopeful of monsters and humans living together. They also wish to change Asgore's mind about humanity. 
=== Fella ===
Annoying Dog is replaced by a white dog dressed as a black cat,https://underfell.tumblr.com/post/185276072656/do-you-have-like-a-dog-oc-like-toby-is-being which is the representation of Vic the Underfella.
=== Chrome ===
Chrome (Full name: MonochromeSome info about UF's secret boss) is a secret boss and is the graveyard shift bar tender that cares about his boss a lot. Not much is known about him at the moment.UF secret boss Chrome is a very shy and reserved guy who has grey skin. He was actually inspired by Animal Crossing and "Cream on Chrome" by Ratatat. Chrome uses like every color of the rainbow in the fight.Chrome fight He also has a move called DISARRAY, where he screeches and the sound waves that come from it are a random combination of white and blue.

* There is no Genocide, Neutral, or Pacifist Routes. Instead there are routes, such as the Trust Route (Where Frisk and Flowey manages to Befriend all the Monsters, and monsters now begin to trust each other and the barrier is destroyed), Closure Route (Where Frisk manages to befriend all of the monsters and manages to make them realize the wrongs they have committed, finally finding closure within each other), and the Betrayal Route (Where Flowey pins all the monsters against each other resulting in Frisk getting blamed by the monsters).https://underfell.tumblr.com/post/651913101407584256/embedhttps://underfell.tumblr.com/post/651963560389378049/betrayal-fight-concepthttps://underfell.tumblr.com/post/665613001988145152/a-note-real-quick-about-betrayal-route-busy-atmhttps://underfell.tumblr.com/post/652221672606384128/more-more-morehttps://underfell.tumblr.com/post/652050092213370880/battle-against-a-true-rivalhttps://underfell.tumblr.com/post/651913101407584256/these-are-just-thoughts-and-im-spewing-ideas-ihttps://underfell.tumblr.com/post/689646093419659264/just-shootin-the-shits-at-12-am-for-betrayal-route

== Trivia ==
* Vic The Underfella and Sour-Apple Studios (the creator of Horrortale) are fans of each other's AUs.https://underfell.tumblr.com/post/654639226123616256/this-like-a-year-old-but-now-that-im-aware-both
* The reason why the creator had left for a while was that they had so much going in my life, which stresses them out at the time.https://underfell.tumblr.com/FAQ
** Other reasons was due to that there were too many edgelords harassing anyone who enjoyed the AU and an outbreak of NSFW that everyone directed their attention to instead of what the AU was supposed to be, which they decided to shut it down for everyone’s own good at the time.
* The AU was acknowledged in a BuzzFeed article published on 30 March 2017, alongside various other AUs.https://web.archive.org/web/20231128032141/https://www.buzzfeed.com/wiltingdaisy/10-undertale-aus-that-have-taken-over-the-fandom-2k6ni

* The AU's creator made the fanon designs from Omega Flowey and Temmie as canon, since in his words, "the designs are already perfect".https://underfell.tumblr.com/post/185354748096/fanon-canon
* When asked about proposed battle sprites, the AU's creator said: "Both can work, when frisk first battles them they’re the color their design is most associated to and once you beat them their sprite turns gray. You get to see some important design details when they fight, after you beat em they are now gray, calm, and tired. so... why not both!" Albeit they prefer a darker tone of red, with more color focus over fanon's much brighter red tones.https://underfell.tumblr.com/post/617841409598406656/uh-im-not-sure-if-you-have-been-asked-this
