One day, Sans fell sick. His sickness came out of nowhere and it cannot be cured no matter how many medicines Gaster gave him. Because of the sickness, Sans stayed still on the bed, just laying down or sitting on it under the blanket. The sickness can be seen from his face, half of his white skull was a little bit darker than the rest. Gaster and Papyrus had no idea what kind of illness Sans has, but they decided to take care of him no matter what, hoping that the sickness will soon gone either because of the medicines Gaster gave him, or disappears itself.

But alas, The sickness gotten worse...

A Different Kind of End - Book One - Reset by Toasty-Writer

Hatred is like an infection, if left to fester it only spreads and becomes worse, until there is little to no hope of return. Frisk had abandoned her life on the surface, she had no expected to survive the fall, even less so make friends with the monsters rumoured to live under the mountain. So what happens when she leaves and is all alone once again... What happens if she listens to the flowers advice..... Book one of A different kind of end. I do not own Undertale, or the characters used, simply the story concept.

Sacrifices (Undertale FanFic) [COMPLETED] by Brynwyth

Frisk has freed the monsters of the Underground. Finally, monster kind is allowed to return to the surface. It's been 3 years since then. Yet the monsters still struggle to find their place within the world. Most accept the monsters, but there are those who wish nothing more than the complete annihilation of monster kind. Merely sealing them away is not enough. As ambassador for the monsters, it is Frisk's responsibility to fight for everyone's right to live on the surface. But at the same time, an internal battle rages on within her. Not only that, her relationship with Sans is strained. Trust is not so easily regained after the slaughter of one's beloved, despite it all being erased. Or was it really? The memories are still there. *I have lost interest to complete pre story and post story parts. Please enjoy the main story and the extra tidbits.* Chinese Version: http://fav.me/db7h2kg DISCLAIMER: I do not own Undertale. TobyFox is the creator and owner. Cover art does not belong to me.

Memories - (Sans x Frisk) by BatBanana

"I feel that I'm living in a dream right now, and any moment I'll wake up and find myself back in another nightmare." I say, eventually. "Welp, if you ever do, just remember, dreams can come true," he tells me, bringing my face closer to his. - Chapter 7 The reset button. Just the word is enough to give Frisk nightmares. Temptation grows strong inside her, but if she were to disappear, would everyone else be saved from the peril that a reset brings? Cover art done by me, and I do NOT own all of the characters in this story. Undertale belongs to Toby Fox, but some of the characters in this story belong to me.

Cries of the Fallen (CANCELLED) by VeronicaS189

Rating M because of mild violence :) In the surface once again, Sans just can't be happy. He has seen this too many times, it's just not special anymore. Everyone seems to notice there's something wrong, even Papyrus, and when past ghosts start haunting the older brother, he will have to try with all his might not to let his soul break. A man forgotten by everyone but one. A broken soul. A world without RESETS. Everything could go wrong. HEAVILY BASED OFF CLANNAD. REALLY. AND HANDPLATES.

Colors | Chara x Papyrus by NoellaBerry

~~~ [COMPLETE] After being set free from Frisk, Chara finds herself shoved into a new life that she didn't ask for. She's cold and distant for days, void of a SOUL and seemingly proper emotions. However, there's a certain somebone who refuses to tolerate it anymore. Unlike her, he's kind and unfortunately, always around. When Chara finds herself dealing with unrecognizable feelings, he knows just how to help her. ~~~

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

Undertale:Secrets by ItIsComic

Remaster on my page - check it out! Sans has had an interesting past. A past that even his beloved brother barely even knows of. A past that he wishes could remain a secret. But when the questions start being asked, what does he do? These questions seem so little, yet they cause so much to happen. One little question. "Who is ??????" can change so much. A chain reaction from a single sentence can cause an entire world to crumble. Or maybe two. This is my first book so dont expect anything great. Inspirations: The "Better Times" trilogy by: @ANinnyMouse42 "Royal Blue" by: @dealialestine Started: 24th May 2021 Finished: 29th December 2021 A full 7 months of great fun with this book!

Flowey x Reader: Teach Me how to Feel by xXGalaxieXx

"I told you, can't feel right!" The feeling you get when you're on a roller coaster jolted your stomach as you fell from the edge of the cliff... you hit the ground... and everything went dark. That's the first thing you remembered when you woke up in that honey-scented patch of flowers. "There's no sunlight down here." There's no sky. There's no birds singing in the morning. Everything was different in this new world that you had fallen into, and you were determined to get back to your world. Until someone decides to help you. Now you were determined to get both of you to the surface. Nothing could stop that. "Right...?"

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.

Determination - G!SansxFrisk by Toasty-Writer

Frisk just wants to save monster and humankind, but does she have the determination to do everything she wants? Especially as she has now been blamed for the terrible crimes committed by her sister. G has stopped caring, but can this infuriating woman who becomes his neighbour pull him back into the world and seek for justice again. I'm so bad at descriptions :/ I'm delving headfirst into fanfiction. You guys may not like this story or even read it but I'm going to try. This is a Gsans and frisk story, there will be an attraction between them but it may be slow :P I do not own the characters or their respective AU's. I'm simply throwing my own twist into the mix hoping you like. I do not own any of the art featured in this book, they are just all amazing. Will involve some moderate language, violence and trigger warnings, hence the mature rating, I will warn at the beginning of chapter if there is a trigger warning.

My Fault - Underfell Fanfiction (Sequel to Your Fault) by DragonzRawesomE

{COMPLETED} It has been just two weeks since the event that changed Papyrus' life forever. Too late, it seems, he realized what he had. And now that it is gone, he has fallen to pieces. How, or if, he will be able to cope, he truly does not know. And as if that wasn't enough, there are countless mysteries in store for this burdened skeleton-- coming from people he thought he could trust, and in places he thought that he knew. Will Papyrus ever be able to solve the mystery behind this devastating chain of events? Or will he, too, fall prey to the ever-expanding void that is engulfing the souls of himself and everyone around him? PLEASE NOTE: This book is the second in its series. It contains major spoilers to the first book, as well as this book may not make much sense without having read it first. So, if you want to keep the excitement of the first book without any major spoilers, I HIGHLY suggest going and reading that first. It is titled Your Fault.

An Illness ~ A GasterBlaster Sans Story by JoymerLeMessiah

Sans is struggling with an unexpected, and incomprehensible...illness. With the help of Papyrus and other friends Sans will surely make it out of this conundrum... right? ~Characters belong to: Toby Fox/creators of Undertale ~Any and all character thoughts/descriptions/etc. are from me -cover original image: https://img00.deviantart.net/8d12/i/2015/329/1/c/it_s_okay__you_can_cry_now_by_lemonsandlemonade7-d9i1gq9.jpg

FurtherDown by THEANIMATEDFOX4

Was this truly the last RESET? Sans wondered. But he knew only Frisk would tell, only this young girl would decide his future. He hated the thought of it at first, but hatred began to grow numb after he figured out he had no say in his own future. He had to admit though, Frisk was pretty reasonable, it was Chara who was the maniac. But she was gone now, so what was the anticipating, eerie, feeling that he had in his bones? The feeling that something wasn't right, of course, this timeline was already incredibly strange. The feeling sat in his in the pit of his stomach, tying itself into knots, until that fateful rainy day when all of his questions would be answered. So basically, this is a fanfiction of a fancomic of the game Undertale. Look, I'm gonna admit, I'm little stuck in the Undertale fandom, so this is my of slowly crawling out of it. Anywho, I strongly suggest you read the fancomic which this fanfiction is based off of, DeeperDown, before reading my story. Here, I'll give you a link. http://gettingdeeperdownwithundertale.blogspot.com/ Anyway, enjoy the story, it took me about 11 months to write, so please consider enjoying it, seriously. - Ya Boi, Fox

You and Your Bitty Pals by Blueprint15778

It has been 10 years since the monster broke free from the barrier, and since then monsters and humans live together in peace. But for some reason, monsters have somehow got a mini version of themselves, no one knows how or why it just happened. And for some reason, the skeleton bittys are popular because of their many different versions. You are a 19-year-old girl who lives in New York City in your apartment the problem is that you're all alone( if you're wondering if your family is alive, you just live far away from them), you have a small dislike for people. You wish you could get a Bitty to hang out with it, but the problem is that it costs a good amount of money. So you could never get one or so you thought until one day you find a strange box. This is my first time posting here so I hope you enjoy it! Also note there is some swearing. Note the cover does not belong to me. It came from https://undertale-au-fanon.fandom.com/wiki/Bitty!_Sanses By The Edit Lord Also I do not own any of the characters. Undertale belongs to Toby Fox.

What Lies Inside (Gaster!Sans x Reader ) by Jaethefallenhuman

"You know sweetheart, lying doesn't get you anywhere with me." He said lighting a cigarette and placing it in between his teeth. Vanilla, leather, and smoke is quite the intoxicating smell. "I'm not lying, also who gives you the right to judge if I'm lying or not?" Something flickers inside me, a warm burning feeling that fuels my anger with this asshole. Walking up closer to me he pins me against the wall, smoke dances around his skull in a vary of swirls and curves. "Let's get something straight dove, I am your worst nightmare and I am your best daydream. I can see right through people, ironic right? There's something about you, I know you're hiding something inside." He really is good at seeing through people, but the thing is I'm not like anybody else. The media I use in this book does not belong to me, they belong to their rightful owners! Gastersans is NOT my original character ! He was created by Borurou Undertale was created by Toby Fox Highest rankings #1 Gatersansxreader #1 Gastertale #19 Gastersans

Uwa! So Fate♫ [Sans x Frisk] by calmlypanicking

"what tori said, is it... true?" I paused, and I didn't say anything for about a minute. "earth to fri-" "Yes. It's true. So what?" He was silent. "... so what? it means a lot to both of us, and you know that." I continued blushing. But my face was welcomed to a brush of his bony fingers. I stared into his sockets. "but, it would've been better if you told me sooner." My first story, so don't expect anything good lol. None of the pictures I use in this story are mine. All credits go to their rightful owners. Ranked #1 in #friskundertale! Thank you all so much!!

What Is Love? by Rosu-chan

For many years, Frisk never once knew about Valentine's Day. What?!! That's probably what you're thinking. Anyways, Frisk has a huge crush on a certain skeleton who's also crushing on someone else. Will she be able to confess her love to him and live a happy ending? Also...Frisk is a girl in this story ;) UNDERTALE DOESN'T BELONG TO ME. IT BELONGS TO TOBY FOX. None of the used pictures&gif's are mine. And that's about it. Plz follow, vote, and comment in my books. I'll be happy to hear from you. Buh bye!!!!

Dual Stones - Undertale Fanfiction (COMPLETED) by IcyDuelist

Duska has something most people would call a traumatizing childhood which she only escaped from a few months ago. Now she finds herself beneath the very mountain she was born in with monsters around every corner. She decides to start her life again here, in the house with Papyrus and Sans, but monsters don't live the most ordinary of lives either. Duska's past is catching up with her but the wall of friends in front of her may be hit by the impact first. No pictures, videos or any other media belong to me unless specifically said. Will have some swearing in it. Undertale belongs to Toby Fox. Thank you for creating such a beautiful game! I FINALLY FINISHED IT!!!

Origin Of The Bros (Fontcest) by BubblyShip

(Toby Fox owns UnderTale, the cover is my own art, and I'm trying out unusual ships and Fontcest is the next in line following Sansdyne. Why not?) Papyrus used to have trouble making friends, so his Dad decided to new addition to the family would be a great way to make Papyrus a perfect brother! Or, if things spiral out of control, a perfect boyfriend. Gaster really should have considered making Sans' personality not fit so perfectly with Papyrus' before he created him.
