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

"Not Quite Determined" Sans x Human/Monster Reader [COMPLETED] by FloweyTheGrouch

You've lived your life without ever knowing your parents. Despite that you dream big because you don't have much; aiming to become a famous singer and prove anyone who has doubted you wrong. Monsters have been freed from the surface. Of course, you happen to meet a certain Skeleton and his joyful brother as well. But will their past continue to haunt them and will it 'hunt' you as well? Will crossing paths with the monsters lead to self discovery? And what happened to the timeline?! You'll just have to read it to find out. (Contains Smut!) This story is based on Toby Fox's game "Undertale". So I don't own anything from this.

Remembrance - An Undertale Story-DISCONTNUED by MEJ2235

Long ago, two races ruled over the Earth. Humans and monsters. At least, that's the story we all know. There was another race. Technically, they were monsters. Skeleton monsters to be exact. Humans shunned them because they were monsters. Monsters shunned them because humans had skeletons. In retaliation, the skeletons split into two different races. The Surface Skeletons and the Abyss Skeletons. The Surface Skeletons reaches out to both monsters and humans. However, when the war started, they were some of the first monsters attacked and many were killed when they fought with the other monsters. Only a handful were sealed underground but without the Sun to strengthen their bones, the skeletons suffered until they received anonymous help. Very few survived to this point and slowly, they died out. The Royal Scientist at the time and his wife tried to have children. Each time left them severely weakened. Each child dusted until the wife gave up her life to bring a great skeleton into the world. That child is the last of his kind. The Abyss Skeletons shunned all other monsters and humans, considered them all demons. Their society was alike human society long ago. Divided. They believe they are strong and emotions only weaken. The class system was rigid and they possessed a kill or be killed attitude to all other monsters and humans. They thrived underground and ended up building their society in the Underground's own Abyss. It is a shame that only their leader can reclaim their heir from the corruption caused by those demons. Warning: Rated Mature for possible smut and probable gore. I'm sorry I don't know what I'm doing but this ain't for little kids. Also, cover doesn't belong to me. Credit to creator. Found it randomly when I searched up Undertale.

Undertale Determination by StorageLibrary

Casted out by their village and fallen into the depths of the Underground, Frisk has to get quickly used to the fact that they not only have to survive against monsters, but also have to figure out who that Ghost Chara is, that helps them through the darkness of the unfamiliar world... WARNING: PUNS AND JOKES AHEAD!! AND SOME VIOLENCE, cause this is Undertale! If you hated Sans puns, you will hate this story even more. And yes dear readers, your soul will be in shambles. GET IT?? Cause with determination it splits apart! Haha...hah...

EnergyTale-Xenophobia (discontinued) by Inxonix

When Frisk is sent to the underground, and being the pacifist they are,they won't hurt anybody...Or will they?Will the monsters be free from the barrier that the humans placed?Or will they be murdered in cold blood. The fate of the underground is in Frisk's hands now. (IM SO SORRY I SUCK AT DESCRIPTIONS and yeah. this is my first real book.)

UnderAsriel by FatalityWanes

Chara has one objective: RESET back to when they themself fell, and save Asriel from his demise. With all the Genocide Runs the now-free Frisk goes on for them, they're able to amass a big enough collection of SOULs to do exactly that. The only problem is, Asriel remembers everything that happened when he was Flowey. And he isn't too happy about it... In this new timeline, Kelsa, the SOUL of Bravery, falls into the Underground shortly after Frisk. Determined to save her only friend, Kel teams up with a mysterious flower with a face to find them and rescue them from Asriel's notorious freezing chambers. Betrayed by many, and uncertain who to trust, Kel finds herself in the midst of an iron-fist dictatorship, fighting to restore the Underground to the peaceful place it used to be. But... all is not as it seems, and there may be things about Frisk that Kel will wish she'd never discovered... Cover art by yours truly :3 This story takes place after the events of Underhappened. You may wish to read that first if you haven't already :D

Reset (Sans x Older!Frisk) by error-code-707

There are some things you just can't take back. No matter how many times you reset. After breaking free of Chara's grip, Frisk decides to do one final reset before defeating Sans or proceeding to the throne room. But some memories last longer than others, and broken trust isn't easy to repair. Female, aged-up Frisk. Starts out canon and then diverges. Eventual Sans x Frisk. Undertale was created by Toby Fox. I do not own Undertale, nor any of the characters. Some violent action scenes. Cover art is by amazing artists at http://www.zerochan.net/Undertale,Fanart and http://www.zerochan.net/Chara+(Undertale),Fanart

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 *

The Faults in Our Souls ~ Gaster x Reader (Under editing) by _T3chn0_

"Do you not want to go back home? To the surface?" °°°°°°°°°°°°°°°° "No." °°°°°°°°°°°°°°°° "Why?" °°°°°°°°°°°°°°°° "Because my home is right here, sitting next to me." _______________________ You were used to the unfortunates of life. Everyone had them, it was normal, but life decided to take a lemon, freeze it, then throw it at your face. But, it wasn't like it was THAT bad... Until you fell into the Underground that'd been sealed for over a hundred years, of course. Friends along the way help you through the sudden changes in your life, and a bone-ified family as well. (82,110 words) (Undertale does not belong to me, only the characters I added for plot reasonings. You belong to yourself, of course.)

What Went Wrong? by AngelOfTheDead80

~'Disclaimer: This story has a lot of profanity and covers some very very intense or touchy subjects that may disturb some readers. You have been warned.'~ ((Unedited)) After Chara fell into the Underground, they met Asriel a monster inhabitant of the Underground. Soon after that, Chara joins a new family, but their ambition to keep everyone happy goes a little overboard and Chara is flung into a reality of destruction and hopeless wonder. Then many long years later they meet the beloved Frisk, who fell into the Underground, similar to themselves. Eventually everything Chara thought they knew correctly is turned upside down and they as a person are changed forever. ~'The game Undertale belongs to Toby Fox and some of the dialogue is ripped straight from the game itself, too.'~
