Summary
Your name is Sans Serif. Your identification card says so. Your work permit says so. Your residential assignment says so. Your brother’s dependency papers says so. The Ministry says so, and so it is true.
But when you and your brother are rudely pulled into a peaceful alternate universe at the worst possible moment, the entire foundation of your identity is put into question. You are one of several. One of possibly more. You don't trust any of this, especially not that human, yet you can't help wondering... should you even try to go home in the first place?
Or
An old fic I started in 2018 and decided, hey, why not revisit it in the good old '26? Machine troupe but you are a Sans, and make it an Anti-Harem.
...Oh, and did I mention totalitarianism?-

Summary
Waking up as a skeleton surrounded by more skeletons - all of whom you have no idea who they are- is definitely not your cup of tea. Even more unpleasant, the person whose body you stole is still inside and now your stuck with a very unhappy human-hating skeleton! Yikes, sucks to be you...

Where is my "how to raise a babybone for dummies" book again ? [REWRITTEN] by NtBub

Summary
It was cold, so cold, too cold.
You were draining, slowly, as an orange whose juice would be taken....
the warm juice, the warm and red juice. Leaking, through a dam's rift.
You felt like an empty Shell, empty of what it contained, empty, too empty.
You couldn't see anymore, couldn't hear anymore, couldn't feel anymore.
You were surrounded by emptiness. An emptiness that took everything, and nothing at once. Then, Came the light.
and you were no longer… empty.

Summary
You are a skeleton monster who’s lived your whole life on the surface in a small hidden enclave of monsters, the descendants of monsters who escaped the persecution of the War and avoided being sealed underground altogether.
But when the barrier breaks and underground monsters begin to resurface again, your communities begin to emerge as well and begin to integrate back with the general public, underground monster and human alike.
Looking forward to starting a new life free from hiding, you still can’t help but wonder…there’s no way you were the last of your monster kind, right? Where in the fresh hell were there more skeletons?
….and then you suddenly meet ten of them.

Summary
You had forgotten what you used to be like before the war. Who you were before Sans.
You resigned yourself to dying like the rest of the rotting corpses on the battlefield, glorified title of the "Judge" nothing more than another meaningless name to be forgotten. Everyone you cared about was dead and gone, and Papyrus no longer looked you in the eye. You were ready for it to end in a blaze of glory.
You hadn't anticipated being caught in the crossfires of a malfunctioning machine, bringing you to an alternate, peaceful universe with other versions of yourselves.

“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
Nathaniel Walker was an ordinary man who worked as a construction worker to support his elderly parents, but unfortunately met a sudden end during an accident at work. Upon awakening in what he assumed to be limbo, his regrets and attachment to his life keep him from passing on yet unable to go back since death holds a cruel finality. In the end, the void takes his soul and he fades into nothing.
...Only for him to wake up in an underground lab, confused and afraid, while questioning why he's a skeleton... and a child at that.
Nathan has never heard of Undertale, so he's experiencing this world for the first time, unaware that his mere presence has a drastic change on the story you might be familiar with. Regardless, his goal eventually aligns with all of monsterkind, which is to reach the surface so that he may try and find his family again. However he may just find a new family while he's down there.

Summary
Life is a funny thing. Sometimes people grow up and go to school and have a career, some become travelers, and some find solace in a domestic lifestyle. Others are born and then turn into a Monster when they were seven. (Hey. Thats you.)
Monsters were released from the mountain 16 years ago and when they were released, boom! A small percentage of the world turned into monsters overnight. You considered yourself a monster more so than a human. Especially after your mother dropped you off at the facility, and didn't look back. And after all this time, all there is to do is look forward.

Summary
You were quiet for a long moment. “i’m supposed to be dead,” you told the skeleton.
“… you’re not,” he replied, after pausing for only a second. “there’s no supposed-to with you. you were in the anti-void, not an au. you nearly died, but i fixed you.” His voice was quieter than before, and his head was slightly tilted, like a curious dog. “i don’t normally bother to do that.”
“then why did you?” The words hurt in your mouth instead of your throat. It felt like carbonation below your tongue, and it took concentration to keep that static from leaking into your words. You weren’t used to talking. But this was important.
“why’d i fix you?” The skeleton paused, expression going blank for half a second, gaze flitting down to his scarf. “oh!”
The corners of his mouth tugged up again. “because i want a little brother of my own, of course!”
xxx
You used to be human, before what you called the Blank. You were a teenager, and you liked dogs and the sun and couldn’t remember much more than that. Then you were made into something else.
After your rescue, you try to adjust to living again - and attempt to understand why so many weird skeletons keep trying to adopt you.

Summary
Sometimes life throws you a curveball. For you, your curveball was going to bed looking like a human, and waking up looking like a monster.
A skeleton monster to be precise.
With the barrier breaking, a large surge of magic descended on the town you live in, and transformed you overnight. Unsure what to do with you, and the others changed, you're ushered into a facility until a monster with similar magic can take you to teach you how to wield the now uncontrollable magic you've been given. After waiting in this place for four years, you'd given up hope that anyone would ever want to take you.
What a surprise for you when you find out that someone does. A lot of someones.

You watch them suggest names and argue with each other as you stand there dutifully like a newly-adopted dog. Rus sidles up close to you and looms over you like a hanging specter. His smile does not look friendly.
“How about..Snowy,” He suggests, his grin widening at the twitching grimace on your face.
How to survive a blizzard and nonconsensual teleportation to a dilapidated sci-fi basement.

Summary
The Monsters emergence to the surface had changed the life’s of many.
There were some who had a hard time believing it wasn’t just a hoax, the only changes in their lives being the occasional glimpse of a Monster shopping at the local grocery store.
For others, the change was more severe.
Mimics. Humans whose soul reacted to the wave of magic that circled the world over when Monsters broke the barrier.
Their souls altered their bodies over night, mimicking the appearance of random Monsters. Their very DNA changed, leaving millions scared and confused.
She was one of them. Gathered up and put into the Omega Mimic Adoption Agency until a pack decided to ‘adopt’ her.
She can’t except this new life.
She won’t.
She’s still a human- right?
Or: soft and angsty recovery/found family/romance A/B/O skeleton poly fic where everyone is actually in the poly. Everyone is healing, 50 something years post emergence Swapfell, Horrortale, Underfell, Underswap and Undertale mashup, plus one very traumatized skele MC learning to live and not just survive.

Where you, as the reader, are Sans. And your best friend is.. Papyrus? And now theres Sans? And Papyrus? And Papyrus and Sans and.. This guy says his name is Dust? And that guy looks like he's covered in gunk, and why is this Papyrus calling himself Stretch?
Blurb;
“Do we call each other Sans and Papyrus?” He beats you to the question the moment you open your mouth, startling a chuckle out of you. You walk over to him, draping yourself over his shoulders with a long-suffering sigh. “I guess I could just call you bro. Are you the older of us now?” You blink, looking at him through the mirror.
No update schedule, I can barely remember to write. Ill try though!

Summary
The world was turned on its head when monsters emerged from Mount. Ebott. Not only because of the whole other civilization that laid forgotten under the mountain, but the magic that was released with them. It didn't just change the world, it changed the people. Literally. Over a third of the world's population turned into monsters, horns and fur and tails sprouting from their skin. The lucky ones were further away from the mountains, their turning being gradual and generally painless.
You were unlucky enough to be in Ebott City when the monsters emerged. Your turning was recorded as one of the worst cases, turning you into a skeleton. The turning was so bad that you had stayed behind in the converted mental hospital for a full year, learning how to cope and adjust to your new form.
You can't stay forever, though, and it was now time to go out, to be released back out into the real world. It was time to get back to it. And you had a very generous house of monsters ready to welcome you in and help you get back onto your feet.
Content/trigger warnings will be at the start of every chapter if they apply.
