Summary
You ended it all one fateful night, but instead of dying, were swept up in a world of war with a bundle of a skeleton in your arms. With a crazy scientists chasing you for something you don’t even remember doing, figuring out how to escape with your little brother still alive, a life that isn’t quite yours, lots of angst, and even more comfort… this will be quite the wild ride.
Now including a skeleton-house that is becoming VERY concerned for your mental wellbeing, (buried after the much-needed war-trauma,) you have to deal with a whole ‘nother group of wacky skeletons 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
You, dear reader, have been transported into your own AU — as Sans.
Just when you’d begun to settle into this new, bone-white life, one small mistake sends everything spiraling.A malfunctioning machine, a flash of blinding light, and suddenly you’re falling through worlds — each one a reflection of stories you once imagined, and others you never dared to write.
Gaster calls it an experiment. Papyrus calls it an accident.
But Sans — your Sans — knows it’s something deeper.Every jump takes you further from home, and closer to the truth behind the tether binding your souls.
Will you find your way back… or lose yourself to the story you created?Whatever happens — the worlds will never be the same now that you are part of them.

Summary
For as long as you remember, you've only known nothing but cold and the feeling of worthlessness. You once had a source of light in the dark but it no longer exists. Will you find it again with your clouded thoughts and memories? Or will you succumb to the rising waters and drown?
In which, you are an AU sans with severe depression, self worth issues and hazy memories of yourself—just wanting to go home…

Summary
The whiteness greeted you as you woke up again. It felt almost suffocating, especially when the only other people with you didn't exactly look or act normal. You just wanted them to emote, even a little bit.
All you wanted was to not be alone but no. You were reborn as Ink after you died in a lonely ditch. Now you have to navigate the vast Multiverse with your knoweledge of your last life. As you get friends and foes alike, you notice that not everything you know is trustworthy. Especially when you're a little lost skeleton with questionable ability to feel.
After all, anything could happen in a place this big.

Summary
You've been in The Void for so long that you can't recall anything. Then you find a way out in the form of a skeleton that uses the damn thing as an express highway. Well, sort of. Only he can see you. Your memories are being weird too, since everything seems so familiar even though you can't recall anything.
Then the human falls, and everything goes downhill.OC-centric fic written from second person, it's not all angst but there's basically no comfort for everything that goes wrong (at least at the story's current point). Arc 2 is multiverse stuff
Arc 1: Rock Bottom, 1-11

Summary
The taste is what drives you. The smell motivates you. The feel of dust between your fingers, the sound of screams and begs echoing in your ears, watching them dissolve right before your eyes.
The sensation of LOVE filling your body.
You had long grown used to the feeling of gaining level after level, over and over all for your entertainment.
When it was all ripped away from you, the emptiness was too agonizing for you to truly focus on your newfound lack of flesh and the magic seeping from your bones.
Kill first, ask questions later.

You were a normal human. You went to college, you had a life, friends, family, etc. Apparently, the void didn’t care much for happy endings, and you find yourself strapped to a table in an underground lab.
It’s fine, you have plot armor.

Summary
Getting up in the mornings is never an easy thing. Getting up in the morning to discover that you have taken over the body of Error isn't any easier, either. Now you are trapped in the Anti-Void with a constant stream of voices, confused, excited, and just a little hungry.

Just some short warm-ups that I have written. I might flesh them out into a proper story one day.Sorry guys for the massive time between updates, I am very bad at that apparently.

Summary
You lived an ordinary life, going with the flow, until at one point, you stopped living.
..
.
For some reason you are alive.
Hmm, not that you're complaining, but the last time you checked, you were definitely dead. And you definitely weren't a skeleton.-
A man is reborn into a Papyrus of an alternate universe, which, in fact, he created himself. Oh, if only it weren't for those memory lapses...

Summary
Sans did not remember his previous name, only that he had been human. Rebirth in Undertale was novel, but he adapted, until he realized that the universe he was in was not the original one.
Unfortunately, it was too late when the machine took him to another universe, into a room full of skeletons.
——————————————————————————————
Sans no recordaba su nombre anterior, solo haber sido un humano. Renacer en Undertale fue una novedad, pero se adaptó, hasta que cayó en cuenta de que el universo en el que estaba no era el original.Lamentablemente, ya era tarde cuando la máquina lo llevo a otro universo en un cuarto lleno de esqueletos.
Nota: Sé que suena como tragedia, pero en realidad es una historia bastante esponjosa de curación, o al menos eso intento. Nuestro protagonista tiene mucho trauma y lo va a sanar en una mansión llena de esqueletos incómodos

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
You really should try living a little, but it's kind of hard when you're literally Death. The other immortals might be your best shot at happiness, even if it'll probably look really bad to outsiders that the three dark sides of the multiverse's balances are hanging out.

Summary
Dust never wanted happy endings, he never needed them either. But after he lost his sense of purpose, is there hope? Maybe the infinite loops of resets and killing everyone dragged him into that conclusion. Maybe he could live in a sense of peace and tranquility. But the multiverse has other plans. The poor guy's torture of resets never ended, even after being dragged out of his AU. Essentially nobody remembers this. Nightmare thinks he's delusional and his 'friends' already know how crazy he is, so there's no point in asking really. He swears something bigger is going on here, and it's dragging him INSANE.
Maybe the guardians of creation and destruction have to do with this...

Summary
One day, or is it night, you wake inside a basement with a familiar skeleton staring down at you in shock. To your surprise, you know him, and the others that live within the complex. Each skeleton has a secret. Including you.
How would they react if they learned they are nothing more than fandom created characters from a beloved game? What would they do if they ever learned you were once a human?
