An Oath of Mercy || UnderFell Sans x Reader by StrawberryMilkSnake

[This is old & terrible. Read at your own risk] One clumsy moment and a broken leg are all it takes to leave you at the mercy of the very edgy and very hostile monsters of the underground. Thanks to your knowledge as a doctor (and oath to do no harm), you're able to convince the Great and Terrible Papyrus to keep you alive. But how are you going to find your way back to the surface with a bum leg and a short skeleton that doesn't seem to like you? | - UnderFell Sans x Human Reader - Enemies to lovers but Fell is the only one hating - Your leg privileges are revoked, and Fell needs to wash his mouth with soap - Flowey is an equippable companion and decides to help you cuz he actually gets something out of it - My own interpretation of UnderFell (tho from what I've seen it doesn't really have a narrative anyway)

Changing The Game by Starlessz

One month before Frisk falls into the Underground a different human falls, someone that is not from this world, but from ours, and now they have the power to change the world as they please. What will they do, will they do the genocide route and become a megalomaniac? Nope, they want to be everyone's friend and get their version of a perfect ending.

Chainsmoker [ Gaster!Sans x Reader ] by morrow-

Routine. The entirety of every living thing is dominated by it, human or monster. Everything HAS to be the same. It was in this that you were the exception. For you everything was new, every time line a detailed altered in order to satisfy your sadistic desire for a new ending, whether it be only a few details of dialogue altered or something else entirely. Monsters you once considered family you now butcher and slaughter without a second thought, after all, that's what the Reset is there for, right? And all at once it stops. Your small hold over the Underground is ripped away from you and you are thrown into a dying timeline, monsterkind's final attempt at self-preservation. You're alone, completely and utterly alone. Except one. And he has a bone to pick with you.

A Blind Tale [G!Sans x Oc!] by d-chibiusa

This is a Story about Tora (my OC) and G!Sans: This is a little project that I don't expect to blow up all like that. I'll post the chapters as frequently as possible, and I'll take AU requests when the time comes. I hope you enjoy this silly little Tale. ( ' ▽ ' ).｡ｏ♡

Reincarnated as Sans twin brother by Sansdoll123

The reader wakes up to a new life as a monster skeleton. In a new world, that's filled with monsters, humans, and magic. But instead of living their new life to the fullest, they will have to survive Gaster's experiments and war with humans. Just because Asgore became mad for absolute control over his citizens and the humans. Will the reader and his brothers find their freedom and a place to call home or die trying?

Don't Forget [Sans x Female Reader] by GabrielXander

You would think that with how shit your luck is, you would've been dead day one since falling into the Underground filled with scary monsters and a few spooky skeletons. However, much to your surprise, that did not happen (yet). You know how you ended up here, but you don't know... HOW. You're actually in the GAME Undertale now. And to make matters worse, there are some people who KNOW. You're surviving the best you can, but things are only going to get weirder from here on out. Gaster apparently needs your help? You're using the DJ to go to different AU's? You are gay now?- Okay, maybe that last one is just a joke, but still! You can only hope that your instincts are enough to keep you alive in these trenches. On God, they tryin' to drown you in this hoe! {Available on Patreon, Quotev, and Ao3 under GabrielXander}

The Real Me + You by KasiaKaliszka

You've been living in the Underground for the past 2 years as a powerful Spell Caster, you prefer living in the Underground than up top on the surface as you find Monsters to be better company but other Humans do pass through from time to time. Monsters can go up to the Surface but choose not too as Humans do not want them there and will attack them on sight but there are some curious Humans who will pass through the Underground and so to ease what ever discomfort they may have some Monsters can make themselves look Human. You the Reader didn't get to know all the Monsters, for the whole 2 years you just worked and relaxed at Waterfall until you met a certain Monster who changes your life and you change his.
