[celestial-requiem-au]

Recently i've been reading "the scientist" fanfic by talkingsoup on AO3 and its SO PEAK i had to make something

Oh + some classic Soriel shenanigans

[nyehhehhehs]

Question!

What's your headcanons for the coolest skeleton?

Your whole blog is mostly papyrus stuff

So I'd like to think you have some headcanons for the bonehead

Have a nice day! (I don't know how to end this blog)

I usually try to stick more to canon so none of my headcanons are really that interesting, but I did get to draw more papyrus, so that’s something!

Thank you for your curiosity!

Undertale Sans Headcanons: What soul trait they personally like and/or find attractive

Sans included in this post: Sans (Undertale), Red (Underfell), Blue (Underswap), Hop (Dancetale), Nova (Outertale), Dust (Dusttale), Axe (Horrortale)

================================================

Undertale - Sans

Perseverance

This is a man that likes to live peacefully. He's laid back and takes things slow. Some might say that he's a little too slow. Stagnant.

While Underground, he lost his will. He didn't have much purpose beyond taking care of his brother because he saw no point in having a purpose. He couldn't push through anymore.

He's familiar with soul traits. He used to work with someone who studied them intensely. And Alphys knows more about them than any other person in the world, nevermind the Underground.

He knows about Perseverance. Pushing through and moving on despite the setbacks and the hardships. It's resilience in it's truest form, and to Sans, it's a complete pipe dream. Yet, there are people out there who are defined by it.

They've gone through their own hardships and maybe they ended up as disheartened as he is. But they're still here, despite everything, and they carry on. They wake up in the morning. They may not get out of bed, or even open their eyes, but they still pushed through and woke up. He finds that more admirable than anything else in the world.

Underfell - Red

Kindness

When you come from a world that whole heartedly believes in 'kill or be killed', any form of kindness is seen as alien and more importantly, weak.

Back in the Underground, Red would have laughed at the concept of being kind. It's stupid, it's weak, and it's what gets people killed. He cannot afford to give or accept kindness.

Plus, he has a reputation to uphold.

It'll take a while but he can change his mind. He'll start to wonder how someone can afford to be kind. How can someone be so selfless and good that it becomes the core of who they are? And to be able to stand by that goodness, to be able to stay true to who they are despite the warped world around them?

A Kindness soul is physical evidence of a concept so foreign, he didn't think it was even possible. Yet it's staring at him in the eyes with a nice smile and a pretty face. Maybe being kind isn't so bad.

Underswap - Blue

Blue likes all soul traits.

He doesn't have a single preference because there's something in each trait he finds admirable.

Instead of liking a single trait, he likes that humans have traits at all. Monster souls don't have defining traits. They're made up of love, hope, and compassion which manifests as white. It's not possible for them to be any other colour (unless they absorb a human soul).

Humans on the other hand have an entire rainbow of colours. They are able to have a characteristic so strong, it literally makes them who they are. And he loves discovering what makes people, well, people.

Meeting humans is like a puzzle. The more you get to know them, the more you find out what makes them so unique. You get close with them and before they know it, they're best friends with the most magnificent skeleton in the universe.

It gives him two of the best feelings in the world: solving a puzzle and making a friend.

Dancetale - Hop

Integrity

The act of dancing is the purest form a monster can take. While the body is the physical form of a monster, dancing is the manifestation of the self. It is them, wholly and purely them. As such, it's not possible for a monster to lie about who they are. They can supress it, they can hide it, but they cannot lie.

Humans on the other hand have no such manifestation. Some can dance but it's not a sacred, integral part of your being. It's considered nothing more than a talent.

So if humans don't have dancing, how do they even know who they are? The answer is, they don't.

But some try. Some find themselves and try their damndest to protect that. They want to be themselves, wholly and purely. And it manifests into a pure soul. Being themself is who they are.

Hop wants to be like that one day. Maybe someone can show him how.

Outertale - Nova

Bravery

People often define bravery and courage as the ability to act even when you're scared. It's more than that. It's knowing that something is going to hurt and doing it anyway. It's trusting that you will be okay in the end.

It's being able to sit out and look at the stars, knowing there's a chance you'll never touch the ground again, yet cherishing the sight before you.

Being out in space for so long, he knows how terrifying the unknown can be. Out here, one wrong move and you're dead faster then you can blink.

Yet here humans are, doing stupid things anyway because they're curious. Curiosity is one hell of a drug and he'd be lying if he said he wasn't addicted.

He wants to know everything. He wants to know the science behind it all and the only way to do that is going out there and discovering it for himself.

And having someone by his side who'd go through hell and high water to discover it with him? Heh, he certainly can't complain about that.

Dusttale - Dust

Patience and Integrity

He likes these two better simply because the colour is so distinct compared to the others.

I headcanon Dust as colourblind due to his high LV. Don't ask me how that works, I just think it's neat.

As such, he sees red, green, yellow, and orange as similar/the same colours. Since he doesn't really like red anymore due to it reminding him so much of the player, any other colours that look similar are forever ruined.

Even if you told him that your soul is green, all he'd be able to see is the player. It'd take him a long time to trust you, and to repress his urge to kill you upon seeing your soul.

The only colours that are relatively safe are cyan, blue, and purple. I say relatively because while he can distinguish purple from red, the trait it represents reminds him of Determination.

Determination allows people to live on despite death, to push on and try again. Perseverance is the ability to push through despite the circumstances. They're too similar for Dust's comfort.

Integrity is fine though. It's a nice blue colour that he can't mistake for anything else and the trait itself is also something he quite likes. Staying true to yourself and standing by your principles is something he used to encourage.

He used to judge people on their principles so seeing someone he knows he can trust to not break them is a breath of fresh air.

Patience is probably the safest of the three. He easily mistakes cyan for white which remind him of monster souls. While he does have bad memories of seeing white souls, courtesy of wiping out the Underground thousands of times, he has faint memories of happy times with his brother. White has positive connotations to him. And if he were to meet a good human with a Patience soul, he can start to associate them with white as well.

Patience, he feels, is generally a good trait to have because he knows they won't mind if it takes years to get to know him. There's a chance they'll stick around because that's just what they do. They wait.

Horrortale - Axe

Kindness

Axe is a simple man. Decency was not something that was commonly practiced in the Underground so any form of politeness or general thoughtfulness makes him fold like a lawn chair.

Plus, Kindness is easier to manipulate than the other traits. It was the easiest way of doing what he needed to, whether that was to lure a human in, make them feel relaxed and catch them off-guard, or straight up toy with them until he's bored.

But when he doesn't need to do that anymore? When his brother doesn't need food or he doesn't need entertainment? When the Underground is safe on the surface with access to all the food and fun they could possibly want?

It makes him feel odd.

There are people out there that look at him, see the giant hole in his skull, the unnerving red eye, the bloodstained bones, the creepy grin, and still decide to hold out their hand and introduce themselves with the biggest smile on their face.

They tell him they thought of him the other day, they invite him to hang out with their friends, they pay for his food when they get take-out. And they do it not because they have to or because they want something from him.

They do it because they're kind.

He appreciates that more than they'll ever know.

Howdy!

I was wondering how the papyri boys (or whoever you’d like to write for!) would react to an SO who has major cuteness aggression and has no choice but to nuzzle them aggressively or bite them.

Thank you for your wonderful writing and I hope you have a lovely day/night!

I get cuteness aggression so bad sometimes

Undertale:

Papyrus:

He's a little shocked the first time you do it and just watches in mild concern as you nibble on him.When you explain it he is so pleased he's cute enough to trigger it in you. Will accept your nuzzles and bites like it's any other form of affection and might nuzzle back into you with a skeleton kiss.

Sans:

Oh wow he's a little surprised at first y'know he's just not used to being a chew toy. Definetly makes as many biting jokes as he can anything related to teeth(I'm not creative enough to come up with some bite me (hehe)). He'll nuzzle you back gently and just accept his fate when you attack him with love.

Underfell:

Edge:

He's a bit put off at first and thinks you're having an episode the very first time. Doesn't understand what's going on when you're knawing on his bones in affection. Concerned look and slight disgust over the saliva on him the first few times but he gets used to it and just accepts it with mild exasperation. The nuzzles he can deal with better and will nuzzle you back in skeleton kisses though not as aggressively.

Red:

Absolutely thinks you're fucking weird but you're his weirdo so he's okay with it. Does not get you at all when you're straight up chewing on him but he understands this is one of your ways of showing love so he's just taking it with a grin and a head pat. Gets the nuzzles and will aggressively nuzzle you back with skeleton kisses while he holds you down so you're forced to accept them.

Underswap:

Stretch:

Thinks its nice and loves this form of affection as much as any other kind. Will aggressively skeleton kiss you back. 100% willing to return the energy. Doesn't really think of himself as cute so when he does something that's clearly adorable he's always a little surprised when you basically affectionately attack him.

Blue:

Also has cuteness aggression so he understands you. Nuzzles and bites you back just as aggressively and with just as much love. Sometimes he'll "fight" back and gently push you away or pin you down so you can't do anything and then he'll cause a counter attack.

Horrortale

Willow:

His brother has the worst case of cuteness aggression out of all the boys I write for so he's used to this. Will return the nuzzles and let you bite away at his bones as he gently pets your head. He doesn't understand what you two find so cute about him but it's kind of nice to think he's cute enough to cause an aggressive response.

Axe:

Oh yeah he loves this. Just stares at you with his big ass eyelight as he purrs loudly while you nibble on him. Nuzzles into you affectionately and so hard he knocks you over sometimes, he doesn't stop when he does either just climbs on top of you and continues the love attack.

[glitching-time-bomb]

How would the UF, HT(if you right for both of them), and US Bro's deal with an s/o who's really touched starved anc tends to follow them around like a lost puppy/duckling?

UF, US, and HT Brothers' with a Touch Starved S/O

Underfell:

Edge:

Please be patient with him... Edge isn't exactly someone who's accustomed to physical touch being seen as a positive thing

In his underground, the most "affection" given out was typically some kind of fight or something similar as to avoid being seen as weak

But as soon as you're able to convince him that touch doesn't have to be violent, that it doesn't make him weak for accepting and giving it, he makes it his number one goal to give you every bit of affection you want

You want to hold hands? He'll do it. You want to cuddle with him? He'll scoop you up and carry you around with him as he goes about his day, because we all know he isn't the type to sit still for long

While he may be a tad bit reluctant to do anything in public (again, everything in the underground taught him it was a good way to make both of you seem like an easy target) he'll still try to slowly warm up to the idea of holding your hand while out on your daily errands

Red:

Just like every other monster who was raised in the underground, Red is reasonably wary about touch

He's easier to convince than his brother, and as soon as it clicks in his mind that it means he gets to be close to you, he's never going to leave you be

It isn't uncommon for him to hug you from behind while you're going about your day, whether it be chores or otherwise, and you can feel the way he sags against you

Most people wouldn't expect skeletons to weigh all that much, but oh boy is he heavy when he does that. It's usually enough to make you have to stop what you're doing to pry him off of you

Red will usually snag you by the wrist or something to pull you onto the couch while he's lazing about for cuddles - even if he says he's doing it for you more than for him

Out of all of the boys on this list, he's the most smug when it comes to PDA and will show you off to anyone he can

Underswap

Blue:

This poor skeleton never, and I mean never, sits down for more than a few minutes at a time during the day, so good luck convincing him to stay for cuddles

That said, he is all for giving you the affection you're clearly starved for. It doesn't matter if he's busy or if you're both out and about doing things together

He's the type to give you little skeleton kisses all throughout the day, any time and any place

As for you following him around like a lost puppy, Blue would probably think it's the most endearing thing in the world

Even if he's doing things for the royal guard after the monsters have been freed from the underground, he'll always find a way to involve you somehow so you don't feel so awkward just kinda... standing about

After all, the more time he gets to spend with you, the better

Stretch:

Oh boy are you in for a ride, because he's in the exact same boat

While he might be a little too lazy to actually follow you around everywhere you go, he's one of the most affectionate skeles yet

He likes to drag you to the most random places for the two of you to cuddle and nap at, it doesn't matter where

More often than not, he'll be touching you in some way - whether it be by holding hands, linking arms, or even one of his hands on your knee while the two of you sit together

Stretch can and will throw himself on top of you to cuddle if he ever sees you laying down on the couch or bed on the rare chance that he isn't there first

Horrortale

Skull:

Don't get me wrong, Skull is another one of the skeles who would be thrilled to give you all of the affection you could ever wish for and more

It's just that he's afraid of hurting you in some way. He's always seen humans as fragile, no matter how true or not that might be, and ever since his head was messed up, he has a hard time gauging just how much strength he's using

It's because of that that he'd most likely have you be the one to initiate cuddling or affection. He'll say that he doesn't care when or why, and if he isn't up to it at any time, he'll let you know

It takes him a long while to trust himself to ever initiate anything without the fear of accidentally breaking you, but when he does, you'd better bet he's hooked for life

As for you following him around while he goes about his day, he might be a little bit worried that something he's doing is making you anxious, and that will make him anxious in turn

He'll more than likely turn around to look at you every few minutes to check in and make sure that everything is okay

Sweets:

Like most of other monsters who managed to survive the famine, Sweets's body is kind of twisted. He knows that he tends to tower over basically every human he's met, he knows that his bones are just a little bit more pointy than they once used to be, and he's afraid of hurting you just like Skull is

Of course, that doesn't change the fact that he would do anything and everything to keep you happy

He'll get used to just... scooping you up and carrying you around with him. It doesn't matter if he's in the middle of doing something like gardening or cooking, though it isn't uncommon for him to set you down on the counter or something similar so he can have both of his hands free

Even if he has a hard time sitting still or relaxing, it's easy to calm both of you down when he lets you sit in his lap while he plays with your hair/gives you a scalp massage

He might even joke about getting a wig, saying that he's always wanted hair

Undertale Skelebros Headcanons - They Have A Crush On You

(WIP!!)

Check my bio

Sans -

Pretends that he doesn’t. If anyone asks? It’s a casual denial.

*what? me and (Y/N)? as humerus as that would be, we’re just friends.

He makes an effort to keep you from hearing about any speculation, if someone suspects it that is.

Sans is good at keeping his true feelings hidden a majority of the time. Not even Papyrus knows, but of course, he pries about everything.

A part of why he keeps it to himself is because he assumes it’ll never happen. Why the hell would anyone want to date a chronically lazy skeleton? He can’t even be bothered to pick up his own socks, he’d be a horrible boyfriend.

But, he loves your company.

He’s always popping out of nowhere to “surprise” you.

It’s more or less an excuse to try to weasel his way into spending time with you.

He’ll show up with those god damn “water dogs” or another gag food item to try to get a rise out of you.

Dear God, does he love getting a rise out of you. It’s his version of some kind of self-destructive flirting. Plus, he loves seeing you react in any kind of way. Frustrated, confused, endeared or entertained.

He thinks about you a lot despite trying not to.

Has contemplated intentionally reading your emotions to see if you feel the same but never has. That wouldn’t be fair.

The skeleton is facing a lot of internal conflict, okay?

Doesn’t want to see you get hurt, even if that might mean never expressing his true feelings.

He might be using “protecting you” as an excuse not to be vulnerable too. But who knows, right?

Laying his true emotions bare in front of you sounds like a recipe for disaster, and he’s already been dealing with Papyrus’s cooking everyday for many years.

Papyrus -

When Papyrus likes you, you’ll know.

He’s always around, he’s always trying to talk to you or show off.

Puffs out his chest a lot

If any of his friends asks if he likes you, he’s not going to deny it. He is going to get into dramatics about how wonderful you are.

He’s taken up reading books like “Dating 101” and “How To Attract Your Soulmate In 30 Days”

His new literary interest starts bleeding through the way he talks too. Based on what the books say, it should be more attractive!

No matter where you guys are or who you’re with, if it doesn’t step over anyone else’s toes, Papyrus is going to be opening the door for you.

You show the slightest interest of going somewhere or leaving? He’s jumping to swing it wide open for you.

He often offers for you to come over to his house. Playing host is the perfect opportunity for him to show you what a domestic life with him would be like.

He’ll cook for you (always spaghetti), clean for you before you even have time to finish making the “mess”.

And you better believe he has every intention of keeping that up if he manages to woo you. Not that you’re asking for it in the first place.

Sometimes, when he thinks you won’t notice, he’ll just stare at you and imagine what it would be like to kiss.

Yes, he has the most stupid look on his face when this happens.

He wants a shower of kisses from YOU!

For months, he’s been trying to find a way to tell you how he feels. Nothing ever seems to feel adequate enough though. The depths of his feelings are TOO GREAT for the words he’s tried to use.
