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
There, standing tall, and incredibly intimidating was someone in full armour with a huge sword stuck in the ground. It was pretty much dark except for the stars, and the fire magic from the King and Queen.
Their black cape was difficult to see in the darkness, but Sans was reminded of those action figurines Papyrus liked to collect, particularly the knight ones.
And, that sword was glowing.
Sans cursed and hoped that he wouldn't have to fight, he doesn't the energy left after the climb.
"..Tell me," the voice was husky and feminine, and Sans suppressed a shiver at the tone.
"Will there be a war?"

Summary
Escaping humanity isn't something everyone thinks about, much less wish for- but the fae realm is notorious for allowing those who wish for safety into its mysterious home.
You're going to find yourself anew, rebirthed into the fae realm with more power then you assume at your finger-tips. Hopefully you realise sooner rather then later how much power you hold at your finger tips.

This is a bad sans reverse harem fic, whilst MC is an oc of mine, it can 100% be read as a reader-insert fic.

Summary
Reader is an exhausted retail worker with nothing in life to look forward to but finishing her shifts daily, coming home, and playing her new RPG VR dating sims game called The Skeletons’ Castle.
She knew she was probably weird for preferring a monster romance simulator over the ones with the usual ‘hot’ anime male options, but it had just the perfect amount of horror and mature themes she was looking for.
One particularly hard day in her life, reader turns to her game to escape, this time restarting a save file after a particularly brutal ending that leaves her disappointed. What she doesn’t realize, is this is her last and final play through, because she gets transported into the game as a random side character, not even as the main character! And now she can’t exit!
How will she survive this intense game, or rather, her new reality?

Summary
You and your family have been free for five years. And it feels like a lifetime compared to that hell. It still doesn't feel real to you. You keep expecting to wake up and be in that fucking cell.
But, you don't. You all got out, relatively safe and sound. You even had a real home now. No more scientists, self-proclaimed researchers, experiments, or punishments. You didn't live in a lab anymore, you lived in a big house deep within a forest. Everything was amazing and nothing could change that.
Then you got some new neighbors. And one, in particular, was seemingly hellbent on getting you all to abandon your home. You may have never met them, but you already pitied the poor bastard for starting a war with you.
Nobody fucks with your family and gets away with it. Nobody.

Like Sans Through The Hourglass [On Hiatus] by ShaggySkull
Fandoms: Undertale (Video Game)
13 May 2025

Summary
If the vague and not-so-vague threats hadn’t scared her enough already, a towering, scarred, evil-looking version of the super-strengthed Papyrus she knew charging towards her was enough to cause Em to panic an understandable amount. The blue skeleton prepared himself, the purple skeleton looked on in annoyance, the orange skeleton hung on for dear life, Rus and the red skeleton looked on in bored, sadistic amusement, and Evil Papyrus took no heed of her pleas.
“Stop!” Em yelled, throwing her hands up. A tingling, twitching, trembling sensation not entirely unlike what she had just experienced tumbled from her chest, spreading to every inch of her body in a flash. Now separating her from all of the other skeletons was a faintly glowing dome of light, just barely perceptible to the eye.
What was not barely perceptible to the eye, and unfortunately very, excruciatingly, perceptible was Emery’s pants falling down to her mid thigh and her accompanying screech before she righted herself. Though... mid thigh may not have been the correct vernacular used here. Mid femur would suit the situation much more accurately.
It would seem as though Em was now a skeleton monster.
