Summary
Wake up buried in snow, alone, and with no memories?
Check.
Kepp seeingg numbers, words, and text floating around every object and surface as far as the eye can see?
Also check.
Why does every person he meets say he needs help?!
His perfectly fine if you ask him."I wonder what determination taste like"
Note from the author:
This is my take on Fatal Error—a much more none canon, this isbt even OOC this is just straight up diffrent person with the same name, amnisiec version of him.
He’s also not fully canon-compliant in terms of power scaling and has and maybe different origin and personality.
It’s my reimagining of him.
Glitchy, lonely, and filled with questions, bad puns, power to blow up annoying people and some more puns.-

Summary
𝙐𝙣𝙙𝙚𝙧𝙛𝙚𝙡𝙡 𝘼𝙐
---
(Y/N) had been in the underground for around a year now, she had done her best to keep herself hidden from the bloodthirsty monsters who sought her out for her valuable soul. She had grown accustomed to living in her small cottage deep in the wood outside of Snowdin in total isolation. She figured it better than daring to tread past the treeline and soon 𝙥𝙚𝙧𝙞𝙨𝙝.
---
"It's your funeral, doll. Harbouring someone like me ain't in your best interest." Sans said with a deep chuckle and a shrug of his shoulders. (Y/N) understood the truth in his words, she knew fully well what he was capable of and that allowing him to stay until he was strong enough was going to be her death sentence.(Y/N) didn't understand why she didn't just use the last flare in her gun and get rid of the problem. But, the thought of pulling the trigger brought a wave of nausea over her. She refused to become like the other monsters of the Underground, all clawing and fighting like vicious animals for the title of most feared.

Summary
Sans didn't know what his name used to be, All he knew was that he was a human at some point, and that he was older then he was mentally and physically.
And when he blinked and he had a tiny bile of living bones in his hands, he knew he would give his life for his new baby.
Even when war crashed on the nation, he took it along himself to fight in the war effort in hopes for a better future for his son, he had later found out the baby was his brother, but he would forever be his son in his heart.
Papyrus was the reason he kept going, to strive for a better future.
Becoming chief in command wasn't a surprise.
It's when he appeared in a basement is what surprised him.
Why is there so many versions of him?
Why are they so tiny?
Why do they keep looking at him like that?
He just wants his son back for stars sake
He needs retirement after this, he's getting too old for this.
------
Or in which a human is in the body of sans, goes to war for a couple of decades, and finds himself in a house full of versions of himself, and tries to take care of his son along the way.

I binged this in a day. it was messy, it was realistic, and it pulled on my heartstrings. read at your own risk because its one hell of a ride.
when i thought it couldn't get worse, it did.
do not read if you dont want to cry
BUUT IF YOU LIKE TORTURING YOURSELF WITH ANGST YOU SHOULD READ THIS!!! ITS SO GOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOD. it's a realistic relationship where things dont have perfect happily little endings. it lets y/n not immediately forgive anything. and for that, i admire.
this will definitely influence my writing.

Summary
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.

Where Have You Buried All Your Children? by Estel_dreamer
Fandoms: Undertale (Video Game)
30 Sep 2025

Summary
Ink was familiar with creating, it’s what he was created to do after all. It was woven into his very magic and essence. Every universe, every variant derived from him in some way, whether it be from being formed by his own hands or splitting off from his own creation into something new. But even so, they were never truly his own. He gave them tangibility, but they gave themselves form, they took his starting point and rushed headlong into the unknown. He loved them all the same, as fleeting as they were.
Ink knew he shouldn’t have done it. He was putting more than just himself and this new universe at stake. But he wanted something that he could call his own, he wanted to be selfish and greedy just this once. He’d seen others have children, have beings tied so closely to themselves that they loved and called their own. He wanted that, he wanted his own child, his own creation.
A choice to be selfish may be just what the multiverse needs though to start repairing broken bonds, to form a happy family once more. Or it might break it all apart once and for all. Only time will tell
