#i just saw ''underfell headcanons'' and went ham

[theradicalace]

Got any underfell headcanons?

FUCK YEAH I DO, YOU KNOW IT

okay okay, let’s do this in an Organized way, by character. under the cut cause it got crazy long

sans:

doesn’t slouch in public, cause that’s just asking to be attacked

personally i see him as being about an inch or so taller than the other au sanses, but it looks like way more cause he’s the only one who stands up straight other than swap sans

he’s super claustrophobic due to past trauma

his jacket was a gift from papyrus, and he’d be absolutely devastated if anything happened to it. 

it’s also waterproof! cause waterproof jackets are neato

he doesn’t wear a collar in my interpretation of the au, despite that being the popular fanon for him. i just think that all the connotations the fandom has given it are super weird and creepy, so i’ve ditched the collar entirely

he wears sneakers outside, not slippers. he doesn’t want to lose a slipper during a fight or something.

for the same reason, he cuts the ends off his shoelaces to make them short enough that he’ll never step on them

he has a neutral route fight this time, but it’s not super hard. still no pacifist route fight

the geno fight is still an asskicking.

papyrus: 

actually the shortest of all au papyruses by about an inch

wears those belts with the seatbelt buckles on em you know the ones

he’s scared of thunder when they get to the surface, bc it reminds him of the earthquakes underground that could FUCK things up. also it just makes him worry abt the ppl he cares abt

he cares SO MUCH about EVERYTHING and EVERYONE

more than once he pushes himself into a breakdown bc he cant fix all the corruption and problems in the underground

he makes sure the children of the underground are safe and as well fed as possible

he’s actually the older brother, because im a sucker for big bro paps

his scarf was a gift from sans, and he’d be similarly devastated if anything happened to it, the same way sans would be if anything happened to his jacket

he doesn’t wear the battle body in this au

he has real armor for in public, and casual clothes for at home

he hates the armor. 

he has no LV or EXP

he is in the royal guard, at sort of a mid-rank kind of thing.

he just wants to help people

he’s the owner of the mysterious lab and the broken machine inside of it. he built it himself. he’s a skilled engineer, after all.

he was working on it with sans, but eventually they ran out of resources for it, and had no time to work on it.

he’s aware of timelines and resets just as much as sans is. he remembers as much as sans does. they cope together. (i just don’t want either of them to suffer alone.)

he still calls everyone to the barrier in a pacifist route, but he ends up getting there before toriel, so he’s the one to stop asgore from hurting the human.

better friends with flowey in this au. sees flowey taking the souls, and keeps everyone distracted.

still spares the human on a genocide route. he doesn’t die in one hit, though. he takes a couple hits. he spares you the whole time.

toriel:

sad, afraid, angry.

she’s seen what anger has done to the underground, so she tries to keep her own anger in check.

it’s hard, but she tries to show kindness whenever she can.

her clothes still have some of the old purple, but they’re heavily patched with red and black.

it’s harder to get out of the ruins in this au, because if the human’s hp goes too low, she stops the fight entirely.

its similar to what papyrus does.

right down to the player waking up in a new room, except its back in the bedroom toriel tries to provide instead of a shed.

she tells the human they will always have a home in the ruins if they so choose.

she answers her phone ONCE outside the ruins, to tell the human to please not call again. she wont answer after that.

alphys:

owned up to the amalgamates very quickly. secrets that big take too much energy and effort to keep.

the amalgamates still spend a lot of time in the labs, but theyre free to leave if they wish. most of them are still waiting to see what else alphys can do for them. whether that means separation, or something else entirely, no one knows.

alphys has MUCH stricter standards for experiments after the amalgamates and flowey. 

no amount of threats or bribery from the king will change her mind

she doesn’t have much time for anime. she still watches as much as she can, but she’s just so BUSY

mettaton:

relatively the same, actually, just with more limbs

flamethrower instead of a chainsaw tho

napstablook:

didn’t get the memo, so they’re still the same as undertale

undyne:

tall. really tall

frustrated

tries to get the human to understand, and to give up their soul willingly

actually relatively easy to spare in this au

once she finds out that papyrus is on the human’s side, she’s won over pretty quickly after that.

she’s quieter in this au, but not by much. only when she needs to be.

her spears are this really cool green-blue-white mix. i’d have to draw it, but just trust me when i say its really cool

her eye was actually not lost to a fight or infection or anything dramatic, she was just born without it.

monster kid:

skeptical of undyne from the beginning

“yo… undyne is… kinda mean. but i guess she’s just trying to protect us, right?”

doesn’t know how to feel

muffet: 

mostly the same, just Even More goth

her prices are still outrageous, but if you can’t afford it, she has a donation box you can give to instead :)

if you donate, her attacks in battle are much easier, and the fight is shorter, but you still have to fight her

buying a treat from the ruins bake sale is still the only way to skip the fight entirely

asgore:

not afraid to threaten or bribe people to get his way

doesn’t talk much. he prefers to only speak when he has to

he’s angry, not sad. his kindness is greatly subdued.

he is… difficult to win over.

ANY neutral route ends with him sacrificing his own soul so you can leave. flowey wont kill him in this au, so he must take matters into his own hands.

flowey:

very sad.

doesn’t have a lot of hope

goes along with the human just to see what happens.

doesn’t have the motivation to directly mess with anyone.

doesn’t follow the “kill or be killed” motto here.

doesn’t really do much of anything until he sees where asgore keeps the human souls for the first time.

suddenly, he feels like maybe…. maybe it can be different.

if it’s a neutral route, asgore sacrifices his soul before he can gather the courage to make the choice he needs to.

if it’s a pacifist route, he manages to snag the souls while papyrus has everyone distracted

the pre battle scene goes a LOT differently.

he doesnt sit around monologuing, he gets right down to business, takes the human souls, and takes the monster souls right afterwards.

“i’m sorry, but this is for the good of all monsterkind”

asriel (before dying)

he was alive when everything was happy.

basically the same

asriel (beginning of battle)

“you look so much like chara…”

“but you aren’t them, are you?”

asriel (first phase)

“you’re not like chara at all!”

“you’re just a cheap ripoff!”

absolutely FURIOUS

HATES the human.

asriel (second phase)

even angrier

“why won’t you just give up and DIE already?!”

lost souls:

sans:

talks about frustration

papyrus:

talks about not being able to fix anything

talks about unfairness and injustice

undyne

talks about her mixed feelings about humanity

alphys

talks about how she will never make the same mistakes again

toriel

doesn’t speak

asgore

talks about how this is for the goof of all monsterkind (similar to flowey, but not quite)

asriel (post battle)

“…you’re more like chara than i was willing to admit.”

“just go. i’m not worth talking to like this.”

“but hey. take care of flowey for me, yeah?”

chara (before death):

mostly the same, but probably could have been talked out of the buttercup plan if asriel had pushed just a little bit harder

chara (narrator):

horrified at what the underground has become

urges the human/player to try and help

mostly quiet during boss fights.

almost silent for a majority of the geno route

as a rule of thumb, the more the player kills, the less chara speaks

chara (genocide encounter)

“…i do not understand.”

“is humanity truly that twisted?”

“or have the new rules of the underground simply infected your head?”

“…your soul.”

“give it to me.”

“i will stop you from ever hurting anyone again.”

(this ends up not being true, but damn if they dont try.)

it takes a lot longer for them to even consider resetting the world.

they want you to sit with what youve done.

it takes an hour for them to come back after you sell your soul.

if you do a second genocide run, you’re fucked. they’re not coming back, and you’ll have to fuck with the game code to reset again.

frisk:

not in control

can sometimes resist the player’s actions, but mostly just getting tugged along through the underground.

on a pacifist route, they’ll happily go along. 

on a geno route, they try so hard to resist, but they truly don’t have a choice.

after the game is over, they live their own life.

theyre a good kid.

none of this is their fault.

largely the same as undertale frisk, if a bit more tired.

theyre like 12 leave them alone

general headcanons:

hurting/killing a child is punishable by death

people mostly arent as murdery as youd think.

there’s a lot of fights, but asgore has put in a few regulations to prevent TOO much death.

dont want the underground tearing itself apart, right?

so mostly it’s just brawls and petty crimes. not a whole lot of straight up murder

still, you can never be too careful.

the “welcome to snowdin” and “welcome to hotland” signs now simply read “snowdin” and “hotland”

#ace rambles #anonymous #underfell #undertale #headcanons #long post #like really long #god im sorry for anyone who tries to look at this post in it's entirety #i just saw ''underfell headcanons'' and went ham #headcanons with a dash of canon

[popatochisssp]

Obviously no pressure, but if you wanted to share your ideas on house pets, there would be great interest from at least one person. But headcanons are closed and I totally respect that (this very ask aside sorry). No pressure to do anything!!! just wanted to let you know that it seems like fun info.

Sans (Undertale): Strongly inspired by a fantastic fanfiction I can’t recommend enough, he has a cat affectionately named Catsup (Norwegian Forest Cat). Of course he does. Pretty typical story here, he more or less went to a shelter, locked onto the biggest, fattest cat there, and filled out the paperwork to damn her to a life of having a pun for a name. He...may have only gone to the shelter because he was hardcore struggling with depression and his brother read somewhere that pets can help a little, but that's...that’s neither here nor there. Catsup turned out to be a perfect fit for Sans in spite of his initial attitude of, 'I'm only doing this to make Papyrus happy'-- she's probably just about as chill and lazy as the skeleton himself, content to flop over just about anywhere, anytime and hang out. Her laidback nature was a blessing for Sans, a first-time cat-owner who didn't really know what he was doing or what she needed right away. A more high-maintenance cat probably wouldn't have been as forgiving and there'd have been a lot more stress on everybody before he got it figured out. Now, he considers Catsup his best little pal and doesn't even need to be reminded to change out her bowls and her litter. He's surprisingly responsible, when he actually really cares about something.

Catsup’s Quirks: Likes it when you gently slap her belly, always gravitates towards the room with the most people in it, often appears in unusual places that it seems like she shouldn't have been able to get to

Papyrus (Undertale): He...begrudgingly missed working with the Canine Unit once the Royal Guard was officially disbanded... It took him awhile to be able to openly admit he was interested in getting a dog, and when he did, he had standards-- it had to be a smart dog, one that could learn tricks and follow rules, unlike a certain annoying creature that’s plagued his life and home and special attacks in the past!!! So he did a lot of breed research, found a local, ethical breeder for the kind he was looking for, and went to pick out a pup. Spike (Border Collie), so named for his incredible coolness, is a perfect fit for his energetic skeleton friend and loves to run, exercise, and learn new tricks all the time!

Spike’s Quirks: Learned to wipe his feet before coming inside just by watching Papyrus do it, hams up his tricks and sometimes does them without prompting, never leaves the park without an impractically large stick to bring home

Sky (Underswap Sans): You will literally never get him to admit the real reason he got a dog companion because he knows in his heart of hearts that it’s such a silly reason... He saw a video online of a dog delicately eating a watermelon and while most people would’ve had a kneejerk reaction of, “I NEED TEN,” but not gotten any, he had the same reaction and just...talked himself down to one. And so came Poff (Samoyed), a big ol’ floofer who’s a lot like her master when it comes to levels of energy and affection. She’s happy to follow him around on patrols, training sessions, and even through obstacle course...so of course, she tends to get very dirty very quickly. Luckily, Sky’s diligence in grooming her keeps her coat as white and fluffy as her namesake!

Poff’s Quirks:  Loves baths, tap dances at the mention of treats, doesn't chew her toys and just hoards them instead

Paps (Underswap Papyrus): He wasn’t really in the market for a dog, himself. He was just along for the ride when his bro was picking up Poff, when he happened to hear the most hilarious sing-screaming sound he’d ever heard in his life. He followed it all the way to the little fellow who would soon be known as Smoochie (French Bulldog), and he sure seemed upset about...something? He never really figured out why, he was laughing too hard from hearing a sound like that come out of something so small and weird-looking. He didn't try to adopt Smoochie that day, much as he loved his sound, but he found himself going back to the shelter a couple times just to check on and play with him. After two or three months with no one else adopting the little prima-donna, he figured he might as well commit and take him home. He's a fun little dude and Paps hasn't regretted it for a second, but he's forever in denial about just how much of a Dog Dad he's become since. It's totally normal to carry your dog around in the hood of your sweatshirt, isn't it???

Smoochie’s Quirks: Screams a lot, will eat food out of peoples’ hands if they’re not paying attention, jumps higher than it seems like he should be able to

Jasper (Underfell Sans): Like most things in his life, he didn’t put a whole lot of planning or forethought into getting a dog. He was out one night, decently drunk, and a friend of a friend of a friend of a coworker was talking about this dumb dog he had that was supposed to be a guard dog but couldn't do it worth a damn because he was too friendly. The guy was yammering about how to get rid of it and something about that struck a chord with Jasper. It was pretty soon after monsters surfaced and maybe that's why it felt...important to him? He was probably just drunk and emotional and soft that he even stepped in or said anything, but it is what it is. He’s a skilled enough conman that it didn't take him long to talk the guy around in circles until he was willing to pay Jasper for the privilege of taking this animal off his hands and in short order, he was almost bowled over by the big dog that planted its paws on his shoulders at their first meeting. Jasper immediately renamed him from something cliché and 'intimidating' to Tubbs (Rottweiler) for how heavy the goofy bastard was and then brought him right home. His brother wasn't particularly pleased and swore he would not be caring for this beast, but he never had to; Jasper kinda missed having something trusting and affectionate to take care of, and Tubbs has been daddy's little fatty ever since.

Tubbs’ Quirks: Shreds even the heaviest duty toys, lays on people as if he were a lap dog, drools rivers if somebody's eating food around him

Pyre (Underfell Papyrus): Who am I to defy literal years of fanon...? His first meeting with Doomfanger (Persian) was about as clichéd as it gets-- a scrawny, dingy, scraggly and matted cat scurrying out of an alley in the rain. She went right up to him and, well... it was love at first mew. He scooped her right up, bestowed a fittingly intimidating name upon her, and took her home with him, in spite of the fact that she looked more like a mutant rat than a cat at the time. After shaving the mats off, bathing the dirt away, and getting her some regular food, though, Doomy actually ends up being an exceedingly beautiful feline! He credits his attentive care and grooming for her pristine, silvery fluff and will brag about it at a moment's notice, but he's just ever so slightly in denial about her sweet and gentle nature. Doomfanger is a vicious killing machine, a true apex predator that nothing stands a chance against! That's...that’s obviously why he carries her around so much... And why he plucks her away from any other animal that comes near her like some sort of mother hen-- he's minimizing the bloodshed! If he let her loose, there would be no survivors!

Doomfanger’s Quirks: Meows in peeps, avid shadow-chaser, extremely receptive to handling

Mal (Swapfell Sans): Hey, anyone remember FGTC? This one cameo’d in that fic, she may seem familiar~ So...he wanted a pet. At first, he thought a cat would be good, fierce independent hunters that they’re reputed to be...but after spending time with a lot of cats and not really clicking with any, he was forced to concede that he was just more of a dog person. In hindsight, of course that’s what he was looking for: a loyal companion to (literally, ha!) dog his steps and follow his orders. Before he can actually, intentionally start looking for one, though, the universe works its magic and he finds one digging around in the garbage out behind the house. The emergency vet he brings the scarred and skeletal stray to tells him that, judging by her injuries, she was probably bait in some dog-fighting ring somewhere and got thrown away when she wasn’t useful anymore. Well. Fuck that, Princess (Pitbull) deserves better than that, and she’ll have it! He takes on the duty of nursing her back to health and earning her trust and it isn’t long before she shows her true colors as the loviest sweetheart of a dog that ever was. She’s utterly useless as an attack/guard dog, but her barks are loud and intimidating, and she obeys commands at the drop of a hat, so Mal doesn’t hold that against her. She goes with him just about anywhere she’s allowed and he shows her off with the same enthusiasm you’d expect for a pedigreed Best in Show dog.

Princess’ Quirks: Wags with her entire butt, will kiss the moment someone’s face is in range, barks at doorbells both real and on TV

Rus (Swapfell Papyrus): He didn’t mean to get a cat, not really... He was just following along with his brother when Mal was kicking around the idea of getting one, and Mal may not have clicked with anybody there, but he sure did. Actually... Kitkat (Manx) may have picked him and he’s just along for the ride. Kitkat was kinda young at the time, a little smaller than all the rest and also...no tail??? But what a personality, loud and playful and super sweet and...when it was time to leave the shelter, he just...he couldn’t bring himself to do it without her, he was in love! It’s mutual, at least-- she latched right onto him pretty much instantly and is pretty much never not with him whenever he’s at home, following him around from room-to-room.

Kitkat’s Quirks: Bone-rattlingly loud purrs, loves to play fetch, prone to 3AM zest for life and zooming all around the house accordingly

Slate (Horrortale Sans): I actually wrote about this one! But the gist of it is...he likes cats. Eventually got confident enough to go get one and zeroed right in on the weirdest-looking, least adoptable cat in the shelter he volunteers at. Slinky (Cornish Rex) was deaf, kinda ugly, and a whole lotta weird, but hell, she’ll fit right in at home, yeah? And so she does! She wrecks a lotta shit and is loud as hell, but stuff is only stuff and Slate’s never had an issue with noise. Actually...she really helps him out with his sleep and focus issues, it’s hard to drop off or dissociate when you have a cat in your lap, yelling at you at batting your face because it’s Play Time or Dinner Time, wake the fuck up!!! She’s a bastardous gremlin, but he loves her to bits.

Slinky’s Quirks: Clumsy and bad at judging distances, loves ankle-looping, insists on sniffing all people-food but never actually tries to eat it

Papy (Horrortale Papyrus): Following the trauma of the underground and the ensuing massive outpouring of empathy from humanity at large, monsters were made aware of many therapeutic resources that they could take advantage of, one of which was therapy animals. Papy naturally thought this was a wonderful idea...for other monsters, who were of course far more psychologically-damaged and not quite so good at enduring as himself. But...his brother does volunteer at an animal shelter, and he goes to visit him on occasion so he's made friends with a lot of animal people. This is how he hears about a therapy dog in need of a new forever-home due to complicated circumstances with her former owner, and well... it would be rude not to offer the Lady (Borzoi) a place to stay! He’s surprised by her appearance at first, having expected something more like a golden retriever or some kind of shepherd??? But he's very quickly charmed by her and actually feels more than a little bit of kinship with her no stranger to being long and oddly proportioned, himself-- and they're both doing their best to make it look graceful instead of weird. Since Lady proves to be a sweet and gentle-mannered dog, Papy just sort of...never bothers trying to find other accommodations for her. She’s welcomed wholeheartedly into their home, which she repays with plenty of unconditional love and effortless emotional support!

Lady’s Quirks: Spins in circles when excited, very polite when begging for table scraps, never barks but howls often
