Summary
You wake up as someone who has nothing left to lose, stranded in an Underground that's slowly dwindling in life. Despite being capable of crossing the barrier, you don't dare to, when you have a personal endeavor and promise in mind.
It's a different story when you're transported into an ideal alternate timeline, where your oath is rendered void. Here, with your various counterparts, you don't appreciate reliving the life of a prisoner-- especially when it's enforced by a reflection of what your Sans could've been.
(OR: In a pacifist timeline, an alternate Sans possessing a human soul appears, risking the newly established peace between humans and monsters. If Classic Sans had hair, he's pretty sure he'd still end up bald.)
[A Various x Sans!Reader fic.]

Summary
The human never killed, but they also never returned. Flowey never regained the power to RESET, but he also never lost his urge to try new things, no matter who it breaks in the process.
Denied the chance to get his old body back, Flowey decided to take one for himself. In the end, he settled on Sans.
Sans' friends come together to get him back. That turns out to be the easy part, because having your body hijacked by an evil flower isn't an experience anyone passes through unscathed in body or soul. The hard part is picking up the pieces of their friend and helping Sans fit himself back together.
Fortunately, he soon discovers that the people in his life aren't the sort of monsters to back down from a challenge.

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.
Tooth rotting fluff and bumbling idiots trying to pspspspsps and offer their hand for our bbg to sniff like a cat will ensue

Sans just can't win. His world is anything but kind to him, and it's only getting worse. Meanwhile, an estranged enigma is ceaselessly beckoning, promising truth or annihilation.

System Error: Accidental Acquisition of Children by Frikisbits231
Fandoms: Undertale (Video Game)

Summary
Error slid down, glued to the tree, his back to the ground, into the lush green grass on the ground. Later, he'd take a look at his current situation and possibly eliminate the place without a problem. Meanwhile, Error was resting, leaning against this comfortable, curvy tree, closing his eyes to feel something, something of the place.
Feel... the familiar ambient magic?
Still no monsters, humans, or standard souls around. Well, no one could hurt him if he got some rest, right?
This time, he mentally prepared himself and repeated the safety tests he felt like a mantra so he could get some rest.
He fell asleep shortly after.
…
Sweetness with hints of security, calm, and the tranquility of dawning rest captured his senses. Something... familiar. Like... like chocolate melting on his tongue. He didn't know how he recognized that either. Still, he pulled the tongue out of his space, to capture it. He caught the sensations, almost becoming overwhelmed by them.
(O: The one where Error acquires an abandoned baby bone, which is, of course, his offspring too, yay...)

Now you're here, in a house surrounded by other skeletons. Skeletons who don't understand you while the only human in the house keeps harassing you and you're new best friend. The only thing that can make this worse is for others to be dragged through the portal from similar places to where you were... Well shit.
