This story will contains things such as ABUSE, CAPTIVATION, VIOLENCE, ect. This is the only warning I will give, so if it's not your cup of tea- sorry about that!

. . .

Death.

War.

Violence.

A world torn apart by two separate races.

In a place like that, can peace even exist?

Will you fight for your freedom as a human? Or lose yourself in the arms of a monster?

[HIATUS] 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}

Universal Surface Angel by Lithriel

Reader insert. What if W.D Gaster didn't just get split between time and space, but actually ended up in your world in an abandoned hospital you called home? Your were a young child he decided to use as experiments to test human determination in said world and breaks physical laws to test human possibility? He knows of the powers you gained from his experiments... all but one, this one allows you to tear realities just enough to teleport into them. Knowing of Undertale you felt bad for the monsters stuck below in their world and wish to help them, but something goes wrong and you end up going to certain AUs and helping them, gaining the attention of some bad skeletons who now desire your power for them-selfish-selfs.

Undertale X Reader [In Remake] by Cat_Maipie

Let's get to the point shall we? So let's look at the list here... You're a... no information? Hm, interesting i guess, I'll have to base it off my observation. Whatever, you're a human, well kind of. You're a human and a monster at the same time, more like in between. Let's say... player? Better than nothing i guess. You're your own person. Sometimes you control frisk, sometimes you don't. You can also move through timelines, and also universes but that may be too risky huh? You'll find more about it soon... THIS CONTAINS VIOLENCE PLEASE BE WARNED! Lemons? Maybe. - #57 in sans 12/14/25 - #1 in floweyxreader 01/10/25 *** COVER : Credits to the person who made it GAME : Toby Fox

Love Me Instead [Sans VS Gaster!Sans X Reader] Part 2 (EDITING) by PineappleGalore001

Please read part 1 if you haven't! When a mishap in a reset happens and a character from another version is transported into the current world and timeline, what happens? Gaster!Sans, bad-skele-boy from EchoTale is confused to see that he had landed in a different, yet familiar world: Undertale! Apparently, in meeting with his 'original' version, they seem to be OK with one-another, UNTIL... (Thank you, @yourebluenow for the cover!) If you have not read part 1, look for it! It has the same name and cover, but without 'Part 2' on the title.

Why? • Gaster!Sans x Human!Reader by sansisnotonfire

'When I was 13, I killed someone. By accident of course... It was the day I found out I possessed some type of power.' You kept it to yourself for years until one day it all went wrong. For your own safety you run away to the depths of Mt. Ebott in hope that the legend was true. But once you fell down you start to realise that this may not be the first time... "You've been here before, Y/N. And this time I won't let you run"

Or will he have to start another one? As for you, will you be able to move on from the past?

WILTED: A Sans X Child Reader Story by Yusuka-chan

[I have decided to do what I always wanted 😄😄]:some people put warnings for these so.....CHILD ABUSE IS DISCUSSED You were, thought to be mute and was horribly abused by your mother and because of the psychological trauma , you can't bring yourself to trust people......youve fallen and you find yourself alone...until a punky skeleton decides to take you in and raise you himself. Maybe this is just what you need and you'll be able to finally warm up to others, or maybe it won't be that easy and there will be struggles along the way. 💖Just as dew refreshes the wilting flower, tenderness restores the grieving heart.💖
