The eigth Soul (Undertale AU) sans x reader (Dark Soul) by QUEENDUBSTEP

A surface AU I made up myself! Summary: You lived your boring life as always until monsters finally reached the surface and spiced things up. You gained a new job through them as a scientist and never thought you would get to meet so many of them in person. Little did you know that monster magic brought up a completely different side inside of you that you didnt even know exsisted, especially a certain skeleton monster who seems to be having the same problems. Can you turn back to normal together, will you stay the way you are or will you be able to part forever in order to live perfectly normal lives? There is no smut. A few small kissing scenes, but not more. I tried to focus more on story telling and relation (I think). [This is really not one of my best stories, so pardon me for the Quality to the end. I hope you enjoy it none the less!]

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

Resets (Sans X Reader) by Memovie360

The humans sealed the monsters underground with a magic spell, after a long war many long ago and thats where they stayed until about a hundred years ago. The monsters had broken the barrier, and the humans were just beginning to get used to the new creatures roaming alongside them. This had caused havoc on your family, your parents hated you, and each other. It all troubled you, so you decided to end it. You stared at the hole leading to the underground, you closed your eyes and fell forward, but what happened next left you wondering, bewildered beyond compare. Now that you have the option to reset, your deciding if you should end everything, but you knew he'd remember. You knew it would phase him, but then you realize your not the only one with this power, and must stop them from misusing it. But will you be able to? Read to find out. (Cover created by me, story may contain a few slightly graphic scenes but anything erotic will not make its way into the storylines, minor tigger warning, suicidal theme IS inside this story, please continue reading, updates weekly, also READ THE PROLOGUE!!! It has background info that is relevant to the plot line)

Conduit Tale-An Undertale Fanfiction Novel by Serena_Walken

(Complete)Hopeless and in despair, Sans never thought he could escape the resets and continues caused by FRISK that tormented his life. But, when he thinks the kid is possessed and stops FRISK once and for all he finds out ... that he never really knew anything after all. No more resets. No more saves. No more hiding. Life will never be the same for the Underground. Souls and Science can be an unforgiving bitch. Relationship: Because of the nature of the way this fanfiction works, there are several Frisks. He knows all of them, but Sans only falls for one, and she is definitely over the age of 18. This doesn't blossom until some time later though, as this is way more than a sweet romance. Buckle up for some tragic dramatic scifi-twisting to the fantasy world of Undertale!
