Your Fault ~ Underfell Fanfiction by DragonzRawesomE

{COMPLETED} Sans' life isn't easy, and living in an Underground society filled with torture, rape, and murder doesn't make it any better. Every single day is a struggle, and Sans tries so hard to fit in with other monsters and live up to his brother's standards, but sometimes it's just too much. Will Sans be able to pull through, or will the darkening thoughts that are engulfing his mind and Soul take control, and swallow him up into a void too deep and dark to ever imagine?

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

Given An Unwanted Second Chance by UndertaleFanatic981

(TW: unaliving thoughts and memories at the beginning. It gets better over time, don't worry! Trauma is difficult to overcome...) You didn't want a second chance. You didn't want to survive. You wanted the sweet release of death. But it seemed like the universe was far too cruel to allow you even that. It took away your memories, your free will to choose whether you live or die...hell, it took the one thing in life you owned! Your own name! And now it seemed like you had to live yet another cruel life, doing things you never wanted done to others. But...at least you could do things your way. Maybe this second chance wouldn't be so bad... (Reincarnated as Nightmare Sans, but unlike other stories, you have no clue what Undertale even is) (WE REACHED NUMBER 1 IN THE UNDERTALE TAG YOOOOOOOO) (9/13/25)

Error; Across the Multiverse (InsomniaSwitch/Fandoms/AU) by RainbowFluff24

(Cover is my Bobo drawing of the story I guess) when ink and nightmare came out to their groups, everyone was supportive... well besides some.... Especially Error who was that one since before when he asked... they laughed and said why would they? they aren't ones for that.... ink was more understandable since he doesn't feel much... When he was about to disappear, he was pulled away.... (this is a backstory to my BalanceBreak AU I guess? <-Ignore this cause you won't understand why... It's a reminder to me)

Reset Reality (Sans x Suicidal Reader) by katzarecoolz

You Decend deeper and deeper, farther away from the surface. Soon reaching the floor, you lie on a patch of flower petals. A yellow flower comes up and introduces him self... Howdy! I'm Flowey, Flowey the flower. Before he could finish his sentence you get up and run To where? You don't know. Hey guys I've never wrote an Undertale story nor have I played the game (tbh I've only really watched memes about it and a few series.) so I don't know much about the characters or the game in general. But I do know some stuff. I guess in a sense this is kinda my own AU but using the general theme of Undertale, Either way I hope you guys enjoy! and leave comments on chapters of ideas or what you would like to see.
