#underswap hc

[thatsafuckeduptale]

The world put Swap sans and Swapfell sans in different universes because if they were in the same one they'd blow up several buildings because they felt a lil silly.

The world put Swap paps and Swapfell paps in different universes because their anxiety would bounce between them so fast it'd cause a demon core reaction.

[magic-hcs]

Got a lil funny scenario for you!

The boy had a lazy free day, sleeping in late. He hears his brother coming home and head downstairs to greet him, wearing only boxers and looking all disheveled. To his surprise his brother isn't alone but has a human accompanying him (for some service they are doing at their house as it's revealed later.)

Turns out this human is their soulmate and the boy is meeting them for the first time looking like this !

Fooooooor Syrup! 😂

I had so much fun writing this! thank you so much for sending in this ask.

Syrup: US Papyrus

Time to cast some magic and see what we'll get!✨

✨✨

Syrup: Ah…

ground, please swallow him whole now, please and thank you.

“bro ya back, did you bring the new coffee beansss witthh youuu…” His words slowly come to a dragging halt as he stares with wide sockets at the human next to Sky.

oh bollocks…

Syrup had been working for quite a while, a day or two trying to crack at this malware failure that his current contractor had given him to fix. And the coffee in his canteen had been running empty, so he decided to go downstairs and fix his canteen with a whole new lot of coffee - maybe a lollipop or fifteen to keep him busy - when he heard the front door close and the recognizable taps of Sky’s boots and his voice. Only wearing his hoodie and some underwear, a thoroughly chewed through lollipop stick hanging between his teeth and bags for days underneath his sockets, Syrup strolled towards the hall, already mumbling his question.

And here he stood now, standing in his hobo looking glory, staring at the human who returned his gaze with widened eyes of their own. A small tug inside Syrup’s soul soon followed, filling him with the feeling of elation like he just found something he had forgotten about but been searching for oh so long. Afterwards, the searing and chilling touch of mortification followed it. Burning his cheek bones a dark orange, and drenching his back with a cold sweat.

The chewed out lollipop stick slips from his teeth, landing on the floor with a tack and his jaw falls open with a clack. A few seconds of absolute silence.

And then, Syrup’s damned sleep deprive and social capabilities decided to merge and introduce itself. “ahooga.” (He had meant to say ‘hello’ or ‘goodbye’.)

once again, ground, you have permission to swallow him hole, please do it fast.

[pixiefeatherkw3]

Based on this headcanon I have

They are amicable but pretty awkward around eachother...

[darkpetal16]

Quick question for all the boys: what nickname would they give to their partner?

ALL?? OK BABE I GOT YOU. but like I can't do an "all" post again there's just too many now lol.

Underfell!Sans (Red): Babe (all), sweetheart (for the shy or introverted babes), doll/dollface (for the feisty babes)

Underfell!Papyrus (Edge): Love (but very sparingly, he’s not fond of nicknames):

Underfell!Wingding (Fell): My dear / My love / My other half / My heart (all emphasis on the my)

Underfell!Asriel (Prince): doesn’t use nicknames unless explicitly asked to. Might refer to you as partner / mate / spouse however.

Underfell!Grillby (Fellby): Sweet girl/boy/pup & Little firecracker.

Underswap!Sans (Blue): Not fond of nicknames but will occasionally call you his puzzle piece. If you ask him to call you something specific, he will.

Underswap!Papyrus (Stretch): Honey, honey bear, honey pie, spicy honey, and if he wants to be ornery / annoy others in public. . .honey bunny wunny.

Underswap!Wingding (Thread): My dear, my little patchwork, darling, marshmallow / cinnamon spice / pumpkin pie.

Underswap!Asriel (Buttercup): Dummy (affectionately). He gets embarrassed by nicknames.

Mafiafell!Sans (Hit): for feminine presenting partner: doll face, sweetheart, lil lady, cookie. For masculine presenting partner: pal, buzz, lil gent, dish. For neutral, mixture of both depending on his mood.

Mafiafell!Papyrus (Boss): He doesn’t do nicknames, per se, but instead waxes poetry for you about you in private. He’d also prefer it if you didn’t give him nicknames in public. Reputation is very important to him and his family and he expects you respect that.

Mafiafell!Wingding (Don): Muse, my dear, darling, puppet, marionette, toy

Mafiafell!Asriel (Heir): Meadow, my haven, my sunshine (if early riser) / my nightfall (if late sleeper)

Slumbertale!Sans (Slumber): Buddy, chum, pal, bucko, friend, fella who naps with me, pillow, blanket, kitten (if you nap often) / puppy (if you do not take naps often), the one who makes plans, my worser half (jokingly), my alarm clock, etc. He’ll come up with obscure and odd nicknames depending on your routine together.

Slumbertale!Papyrus (Mayor): MY RIGHT HAND! There is no bigger compliment because this fella HATES to rely on anyone so if you’re his right hand then you’re someone as invaluable to him as his own right hand.

Slumbertale!Wingding (Abyss): Dewdrop.

Slumbertale!Asriel (Unending): My dream come true, dreamer, buttercup, butterscotch, butter biscuit

Slumbertale!Grillby (Sleeby): His nickname will be dependent on your favorite drink. For example if you like pina coladas he’d call you his sweet coconut, and if you like soda he’d call you his pop-heart.

Horrortale!Sans (Axe): No nicknames unless you specifically tell him to. He just doesn’t think about it.

Horrortale!Papyrus (Sugar): My little meatball, Strawberry jam, rhubarb pie, my berry, love, heart, SOUL

Horrortale!Wingding (Ghost): my heart / our hope

Horrortale!Asriel (Yarrow): butterscotch, cinnamon bun, and sun drop

Horrortale!Grillby (Calcifer): no nicknames!

Reapertale!Sans (Reaper): Nothing set in stone. He'll come up with one time nicknames for puns. Like if you were burned alive & died to met him, he'd call you hot stuff. If you drowned he'd call you a mermaid with lungs. Things along those lines.

Sciencetale!Sans (Doc): he tried nicknames. It came out awkward because he kept stuttering and he was deeply embarrassed so he never did it again.

Sciencetale!Wingding (Professor): Treasure

Siren!Sans (Siren): That’s a human concept, so he wouldn’t choose any. You can tell him what you want him to call you and he’ll accommodate.

Siren!Wingding (Apex): Same as above.

Dustttale!Sans (Dust): Idiot, fool, daydreamer, dreamer, (and very rarely when he thinks you aren’t listening) my miracle

💑 for Blue?

💑 What are my muse’s requirements for a potential partner?

From THIS prompt

Underswap Sans - Blue 💙

In terms of appearance or personality traits I'd say Blue doesn't have many requirements in order for him to get to like you, love is often times surprising and a sudden occurrence in his life and it mainly depends on how well both of you fit together in his mind. He does tend to favor bubbly and curious personalities, however that by no means excludes someone more mature or reserved. Blue does however, has some requirements when it comes to actually being in a relationship with him. The pretty obvious ones would be that SO gets along with his brother, they don't have to be best friends, but he will not tolerate any long-term animosity between his brother and SO - he will always pick Stretch if push comes to shove, love or not. He does also sort of yearn for someone who can look past his innocent and cutesy persona. He does tend to play up his more naïve qualities because he's a bit of a manipulator in that regard, but he wouldn't be able to be in a relationship with someone who constantly treats him like a kid or some sort of pet animal all the time. He's a lot more mature than he seems so he'd most likely look for a partner who can recognize that in him and not make a big deal out of it. (By that I mean won't villainize him for playing up his innocent act) Another that comes to mind straight away is that his SO would have to be comfortable with being active. He's a ball of energy and often looks for new places to visit and new adventures to go on so he'd prefer someone who can keep up and share those experiences with him. If his SO is less active but willing to try and keep up with him it would make him really happy - he'd help you get in better shape and always stay by your side in social events if you're more on the introverted side. As much as Blue likes to mess around and trick people into doing things his way - he's also very much a no-nonsense type of guy. He wants a partner who will communicate with him whenever there is an argument or miscommunication, if his SO is the kind of person who lets arguments linger, shuts down or just refuses to resolve things I can see that being a definite deal breaker for him. He always tries to resolve any issues straight away because he absolutely HATES the anxiety over an argument lingering over his head for any amount of time. Those are the main few that come to mind, there are a few little things he'd also look for in a partner like matching hobbies or general chemistry but all of those are subjective. As long as his partner gets along with his family and close friends, can see him as an adult and communicates their emotions well I can see him falling for any type of personality. He's very flighty so doesn't have a strict type, its more of a sudden "OH! THEY'RE CUTE!" type of realization in his mind and then it escalates from there.

Introducing my designs for Blue and Axe/Horror in the little AU i've been brainstorming!

I wanted to add a few details that would make them distinct enough for the AU, and at the same time keep enough design elements to still make them recognizable.

Here's some more of my ideas for the AU!

The stars all wear a gold star-shaped pin somewhere on their clothes (Blue on his scarf, Ink on his bandolier, and Dream swapped out the pink brooch thing holding his cape). Ink made it for them.

Similarly, the bad sanses wear a brooch that's shaped like a sharpened bone over a crescent moon, given to them by Nightmare.

Upon first arriving in the classic universe, Blue and Axe actually don't recognize each other because they usually hide their pin/brooch when in their own universes (for safety and secrecy reasons). Without those, they're pretty much unrecognizable from other Swaps and Horrors.

In fact, one early arc that I have planned will be focused on Blue and Axe thinking that they're the only one in the stuck-in-the-classic-verse group that's fully aware of the multiverse. It isn't until a bit later that they recognize each other.

[howlsofbloodhounds]

(Headcanon) I think one of the main reasons Error HATES interacting with Ink is because he has a very good memory. So he gets very frustrated with the fact that Ink has a fish-like memory, and it also doesn't help that Error is very spiteful. Even if unconsciously, Error ends up being a box of memories for Ink, since they spend a lot of time fighting and neither of them can shut up. It seems to work in a way.

I honestly love that idea, it’s kinda cute. Imagine if Ink is yapping to Error during one of their fights, maybe something about Dream or Swap or one his dads being cagey or like they’re hiding something from Ink, and Error mentions that it’s probably the surprise birthday party, and Ink’s like “birthday party?”

And Error’s goes like, “did you seriously forget your own birthday tomorrow?!” and Ink goes “Did you seriously spoil my surprise birthday party?!?!”

Underswap Muffet and Undyne!

My headcanons for underswap can be found here

[magic-hcs]

*climbs out of a manhole* hello!, a few minutes ago I got hooked on a song called “be around me”, and I think if ut sans, ht sans, uf sans us sans called s/o baby by accident, kinda they still aren't dating...yet ;)

Thank you for the ask! I've listened to the song and I hope this scenario is what you had in mind. its short.

Bear; Horrortale Sans

Red: Underfell Sans

Sky: Underswap Sans

Time to cast some magic and see what we'll get!✨

✨✨

Sans: You’re very lucky if he didn’t shortcut out of there the second you said “what..?”. You’re also lucky if he did stay and didn’t just deflect and avoid the topic like he avoids picking up his sock. 

In a perfect scenario Sans openly will explain why he called you that. But this isn’t a perfect scenario. So your best bet to get any answers as to why Sans called you that is to ask Papyrus. And what you’ll do with the information you’ve acquired is something only you can decide.

✨✨

Bear: Perfect copy of that meme that goes:

“What?

“what?” 

He could’ve gotten away with it if his bone cheeks didn’t slightly flush that faded blue and if he didn’t sweat like he always does when he feels like he wants to be everywhere except here. Please help the poor Bear. 

✨✨

Red: Man is sweating bullets internally but looking smug on the outside. You see, Red has an advantage, and that advantage is that he always flirts. He’s flirty, even with friends, using nicknames like ‘doll’, ‘darlin’, ‘snack’, etc. He just hadn’t used ‘babe’ before.  It just slipped to be honest. So if he just pretends that it's just another nickname he’ll be in the green…As long as you don’t mind the nickname that is.

Stars, Red really wants to shortcut the fuck out of this conversation, but it will be suspicious if he does. So stuck toughing it out it is. 

There won’t really be any change to the relationship between you, unless you mention it. 

✨✨

Sky: Sky is committed to what he says, he made his bed and he’s going to lie in it. And hope for the best mainly. If you missed it, he’ll just go along with that. But if you did hear it, Sky won’t deny what he said. 

He’s the only one you’ll be getting an honest confession from without needing to prod. Sky leaves the ball in your court. 

✨✨

Thinking something for a while now

That Blueberry goes with The Star Sanses while Blue (more base swap) goes with Red and Classic

One has gone more multidimensional flare than the other because of reasons respectively but they still regard eachother friendly enough
