Summary
Monsters came out of the mountain last year. An unknown number societies filled with creatures small enough to be held with one or two hands. Without their Core, their Souls need to gain ‘magic’ from Human Souls caring for them. So of course, shops popped up all over the place advertising different ‘varieties’ of ‘Bitties’ for Humans to ‘adopt’.
I’ve seen plenty of these poor little creatures up close and I’m telling you, these are tiny people who deserve more than pet status. Not to mention the fighting rings. There’s intelligence in their eyes that I don’t even see in half the Human people I encounter. Not that I’m particularly interested in encountering people. My street cat Emily and I prefer staying at home, making just enough money off of my video game streaming to stay afloat.
Emily is an odd cat. She came into my life freshly pregnant and demanding to be my cat. Her cool as fuck skeletal pattern gave me the idea to keep my identity online a secret by slapping on skeletal face paint. The viewers love it.
Sadly, Emily gave birth just a few nights ago, to a litter of stillborns. She’s been beyond miserable. She goes out every night now, I’m really worried about her.

Summary
“Oh?” Mutt repeated, confused.
“That’s all you have’ta say?” Red exclaimed, bemused. “Your home is gone, and you’re literally stuck in another universe! What do you mean, ‘oh’!?”
“Red!” Edge scolded, shocked at his outburst.
“What!? He should be freakin’ out right now!” Red defended.
“Maybe he’s in shock?” Mutt offered, just as lost.
—
You were reincarnated to a world of war with a bundle of tiny bones in your arms. With a crazy scientists chasing you for something you don’t even remember doing, trying to escape with your little brother, living a new life that isn’t quite yours, lots of angst, NEW skeletons that probably think you’re crazy, and even more comfort… you are in for quite the wild ride.
The new chapters are now including a skeleton-house that is becoming VERY concerned for your mental wellbeing, (buried after the much-needed war-trauma,) and you have to deal with a whole OTHER group of crazy people judging you. AGAIN.
But… in order to have the best comfort fic, you sometimes need to have the worst angst beforehand.
Or, as Gaster once said… you need to break a few eggs in order to make an omelette. :]-

Summary
In a world where soulmates exist, monsters and humans have one thing in common: the first time two soulmates touch, a mark randomly appears somewhere--anywhere-- on their bodies to represent their match.
It still doesn't make relationships easier...but maybe it does make them a little more interesting!
* A collection of Soulmate AU vignettes for the Sanses and Papyri of various multiverses -- Undertale, Underswap, Underfell, Swapfell, & Horrortale *

Summary
You fell into the Underground as a child. You spent a few years there, growing up with the skeleton brothers. Life wasn't great, painful at times, however you had your family with you. A change came to your life, one where you were surrounded by alternates of your skeletons. They were nosey, pushy, and much louder than Papyrus. They were nothing like your skeletons, and you very much didn't approve. You didn't know how to act, you didn't know if you could trust them, didn't know how to trust them.
There were too many factors. Monsters were there that you couldn't be around. But maybe.. some can help you?

Summary
You lived a normal life trying to pursue a medical degree to help others, but when you end up in a hospital needing help, a group of skeletons appears, and they are determined to help you. Wait, Skeletons? No, that wasn't right, monsters don't exist.
But they do
For some reason, anytime you try to face the reality of your situation and remember the time before monsters, you suffer from a debilitating headache. Even memories you don't remember living, classes with or about monsters seemed to appear in your memories! Everyone around you swears that monsters have been on the surface for years, and yet, you can hardly remember monsters existing all the years they've been aboveground. You can no longer trust your memories, can you trust these skeletons?
Will you discover the cause of your new memories? And will you discover why the skeletons all seem to be intent on staying by your side?

Summary
“what’dya mean the surface? i-” As I speak, I try to take a step forward, but it doesn’t work. Which doesn’t make sense, because when people try to walk, they walk, but for some reason, instead of walking, I fall to my knees in frickin’ PAIN. “aghk-!”
My cervical vertebrae throbs and I cough up dust, trying to keep myself steady by keeping my hands planted firmly on the hard concrete floor. Right, I wasn’t done healing earlier.
“papyrus!” I hear Sans shout the name, one that causes me to look up. But it’s not my name… is it? I don’t think so? I need to focus on healing myself, having been rudely interrupted from said process when I suddenly showed up here.
Or, I love the tag “reader is a sans”, or in this case, papyrus, and this is entirely self-indulgent.

Summary
A night out with your roommates' sorority sounded like a good way to wind down from exams season, but your good intentions to keep from ruining someone's nice carpet have you end up in the middle of the forest. In the middle of the night. Very, very drunk.
Good thing you found a random house to sidle up to and ask to use their phone. Less of a good thing that the skeleton monster that lives in it is only placated by your sloppy jokes.

Eventually going to culminate in a "Six Skeletons" sort of set-up, but you don't get off as easy by knowing Classic Sans first.

Summary
There's something terrifying about change, even when it's for the better. In that shithole of an underground, you at least knew it's in and outs. You knew the rules, how things worked, even if you didn't know where your next meal was coming from or when the day would come that would be your last. It was still the same thing. Wake up, go scavenging, reset the traps, come home. Rinse and repeat.
Nothing new happened in an inescapable prison with slowly depleting resources. Just the inevitability that it'd all run out someday.
You knew, intimately, that you'd die there. Accepted it.
Until you didn't.
Until everything changed.

Summary
After your best skelefriends disappear on you with only a shitty phone-call goodbye for 'closure', you find yourself spending months looking for them everywhere -- failing, failing, failing until one certain trail led you to getting lost in a forest on a mountain, had your life threatened more times than you could remember, and made what were only two skeletons at first suddenly multiply in count.
What no one expected, however, was how your SOUL made you hold a secret nobody was aware of, and just how it made every single thing connect to you.
...Unless, of course, you were Sans.
Almost unless, anyway.
Just an advice though, dearest Reader?𝘿 𝙤 𝙣 𝙤 𝙩 𝙙 𝙞 𝙚 .
Boy, are you in for a ride.

Inspired by a tumblr ask that posed the following: "What if the skeles had a SO that dyed their hair pretty frequently. One day they dye their hair color to the skeles magic color saying, " it's my favorite color now since it reminds me of my favorite skeleton!""
If you're interested in a Sans or Papyrus from Undertale, Underswap, Underfell, Swapfell, or Horrortale, there's a chapter in here for you! ;)
