Summary
I made a very canon-compliant Horror!Sans x Reader!Sans fanfic for those very picky readers such as myself. I did my very best to make Y/N ambiguous, so the immersion is top-notch. So it’s gender, bone color, and clothing neutral.

Summary
He was your worst enemy. You absolutely hated that little blue freak, that rip-off of the perfectly good Sans that you knew. His name was “Blueberry”. A version of Swap Sans, except smaller, and more… Soft? He was always making this one face, sort of like the cat emoticons he’d use through text. Apart from his cringe behaviour, he was also fucked up in some other ways. He would plan to do evil things, go through with them, and then get immediately stopped by all of the Sanses who protected (and destroyed) the multiverse. Yes. Even Nightmare wanted that little bitch gone. The little sadistic, wannabe soft boy brat.

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...

Summary
I've never seen another skeleton. Especially not like this...
They were injured. Their leg stuck in a bear trap. Every time they moved the deeper the jaws sink into their bones.
I should have just let them go and left them to their devices, but for some reason I couldn't. Maybe it was because he was an omega. Maybe it was my curiosity, but now I got more to worry about.

Stained Wax and Spilled Ink(Indefinite Hiatus) by FruityAllDay

Summary
Boredom and curiosity are both great motivators. For as long as you can (hardly) remember, you've been reluctant to traverse the AU's. Being an outcode, you had the ability to. However, you're aware of the "storylines" that the AU's have, as explained by your first and only friend, Ink. You happened to be out and about to take a breather when you bumped into the Guardian of AU's. Being the only person you've ever interacted with, you quickly became friends. Albeit he pushed that title on you when he found out you were an artist like him. As enthralled as you both were to learn about each other, he himself was a busy skeleton. A promise was born from then on. Every month, you'd leave the sanctity of your home and he'd take some time off to visit you. Over the course of time, you manage to discover quite a lot about him. Not enough to satisfy you. You felt as if there was still crucial information about himself he caged away, never letting it slip through the cracks. What a mystery he is. You want that to change. But how exactly would you get closer to him? You just need a chance, an opening. To open the floodgates and break open the barriers, to see what skeletons he's got hiding in his closet.

Summary
You don’t know what’s going on anymore.
Everything is blurring together, the constant movement, the cramped spaces. You can’t tell how long you’ve been sitting here curled in a ball. You don’t remember what you look like anymore. You miss someone, but you don’t remember what their name is, who they were. Their faces haunt you in the dark, but at least the dark was safe.
And then there was light, light that didn’t bring pain. And it wouldn’t go away. People talked to you and gave you things. They said they were sorry. They cleaned your skin. No your bones, free from the red stains.
They asked you if you knew someone called Sans and then you cried in their arms until you could cry no more.
