Into The Game >> (Sans X Reader) Undertale FanFiction by Melody4164

It was just a normal Saturday. (Y/N) was playing Undertale for the millionth time. She was obsessed. (Y/N) had played all of the routes. True Pacifist, No Mercy/Genocide, Neutral. She experimented with killing certain characters doing different things. Then, as (Y/N) started a new game, she felt a falling sensation, as if she just fell out of her chair. She blacked out soon after. When she woke up, she was lying on a bed of golden flowers. She knew this place. (Y/N) was in the game. She had taken the place of Frisk and was in the Underground. •Disclaimer I do not own Undertale. It belongs to Toby Fox. I do not own you. You own yourself. I do not own the cover or any of the pictures that will show up in this book• *If you're reading this as a guy please just change the pronouns to he/him/his. I find if a lot easier to just put female pronouns. Thanks! :3 *

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.

Bringing people back into existence doesn't generally have negative repercussions. Not for an entire world at least. So why don't we use the same idea for an all powerful entity and see what happens? Unfortunately, this world might not be up to the challenge. ---- What's this? An Undertale fanfiction? Yes, that's exactly what it is. This takes place after a True Pacifist route so spoilers if you haven't played it (which you totally should, go play now!) Currently being edited...

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

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.

Tomorrow is another day by Comical_Peculiarity

A year after the events of the True Pacifist timeline, a lone flower sits atop a hill. Forgotten and given only the option to wait until the occurrence of another universal reset, he encounters an individual with the potential to incite profound feelings once thought forgotten The story concept is pulled from a friend on Undertale Amino, this is simply a rewrite with his structure of events. Think of it as an expansion. The art used in the pfp is 'Memory' by Hnai on deviantart

This is an Undertale AU I originally planned on making back in 2019 but, I wasn't capable of making all the character designs and forgot about it for two years. A few months ago, I thought about redrawing the only two designs and reviving it as well as changing most of the original plot and instead of making a comic series, I'm writing it so it will be easier to think about more designs. OCs are included in this AU. If you would like yours to make an appearance, message, or tag me to discuss when they can appear. This is season 1 of the series and it will basically follow the events of Undertale because there was a strange, unexpected reset after 10 years of living on the surface. Now, it's up to Frisk to help her friends remember their lives before the reset and save the world before Flowey tries to kill all of humanity as well as monsterkind and Mystickind. Can the determined human survive yet another perilous journey through the Underground or will everyone fall to Flowey's hands (leaves?)?

Write A Note (Sans x Female!Reader) by OreoDaSkeleton

It's only been a few years since monsters have been released from their underground prison. In some towns, monsters are welcomed with open arms. Others? Not so much. Y/N is a 22 year old girl that lives a pretty simple life. Sleep, eat, work, relax at her daily cafe, go home, sleep. Then the routine starts again. However, her routine is thrown off when she keeps running into a skeleton, supposedly named Sans. She would like to get to know him more herself, but there's one problem.. He doesn't talk. Of course, Undertale belongs to Toby Fox, not me lol
