× [Sickness] × || Undertale Fanstory || The Gasters/Skeleton Family by Nanaz_Nazmaki

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... -------- UNDERTALE (c) Toby Fox --------- This have nothing to do with Undertale's canon characters or story. This is just a fan story I made because the idea stuck in my head for a few while and I'd like to share it with all of you. So, enjoy!

Nobody knows who the Riverperson is... nobody but a single Skeleton erased from space and time. So when he's pulled out of the Void, what secrets will be told? What is the mystery behind the Riverperson and the Skeleton family?

Bloodfall (An Undertale AU) by BlackStormWolf

Ever since the death of his younger brother. Things have gone downhill in the surface world for Sans. Alphys died a few months after Papyrus to a disease, Mettaton and Undyne, especially Undyne, had fallen into a depression. Flowey dissapeared into mt. Ebott, not to be found and Sans is fighting depression and insanity. One day, Sans discovers a suspect to his brother's death. A being that is trapping anyone who had either fallen into Mt. Ebott or stayed behind in snowdin for a while. Sans, along with Frisk and Undyne, go into the underground themselves to confront this being. They must encounter the Bloodfall that traps and kills anyone who dares pass by waterfall. (This takes place after a true pacifist run if one killed Sans in a Genocide run, but reset their game before getting to Asgore(I did this in a way to quit the Genocide route). This is if Frisk choses to do this the Pacifist way. I might make a Genocide one in Story Shorts. Also, My Sans is a human, but feel free to interprate him as a Skeleton if you ever choose to use this AU. Just credit me!)

Undertale : Secrets (REMASTERED) by ItIsComic

Sans has had an interesting past. A past that even his beloved brother barely even knows of. A past that, despite being so long ago, always finds a way to bite back. A past that defines who he is - but he longs to erase. A past that doesn't let go, it clings to him despite his endless attempts to escape. And when someone finally attempts to uncover the veil, and fails in the process, what happens next? This book is a complete remake of the original Undertale: Secrets that was made nearly 3 years ago. By remake, I mean that this book takes the general plot of Secrets and basically "tries again". This will reuse elements of the original and cut out the parts I don't like while adding my own new ideas, effectively creating a new book. Whether you liked the original or didn't even read it, I hope you like this!! Inspirations: The "Better Times" trilogy by: @ANinnyMouse42 "Royal Blue" by: @dealialestine Started: 17 March 2024 Finished: Not yet! Undertale by Toby Fox

You run through the forest with your younger sister and kitten up the mountain. You couldn't believe that the hunters found you that quickly. You are (Y/N). You're one of the few mages left alive and have a soul of justice. Mages used to be everywhere but from fear were hunted to near extinction. A cave is near and you duck into it to rest a moment. As you walk further into the cave with Frisk you don't notice the big hole and fall into the underground. Can you show the monsters that not all mages are bad? Or do you not make it out?

Begin Again (Sans X Older!Frisk) by GennacideWrites

COMPLETE *This story takes place after an ending in which everyone is alive but they cannot reach the surface*

(DISCONTINUED) Where Were You? (UnderTaleXFNAF) (SansXReader) by 12DawnLight21

You are (Y/N), a tortured/abused girl who ran away from home bearing a terrifying secret. After falling into the King's Castle, you meet Sans, Papyrus, and their father W. D. Gaster. One year after staying with them, you suddenly disappear. Will you ever get to see your 'family' again, or will you fall under the influence of your terrifying 'secret'?

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!

A few months has passed since Frisk the human broke the barrier and all monsters returned to the surface once again. Join Frisk along with her boyfriend, Sans, and the rest of her friends on another adventure on the surface. (NOTE: This story has its own way so I'll do my own scene first.) (NOTE 2: Same rules again, don't ship - Don't Read and GET OUT!)

Fallen Under is a full-length fan-novel of the game 'Undertale' set in 'Underfell'. This work will not have anything sexually explicit, though there is a (major) gore warning. It is light of heart, but some dark themes including suicide, abuse, and murder are explored. Mt. Ebott is famous for the woods that a child may wander into and never return. In legend, monsters snapped up children from villages, hid in dark corners, and ate the souls of the weak or unprepared. When a young child chooses to flee into the mountain rather than face human capture, they find out that these monsters might not just be characters in old children's stories. Frisk Foster, an eight-year-old child cursed by hereditary blindness, falls into a cavern full of merciless monsters, all of which want nothing more than to steal their soul. Armed with only their sense of justice and kindness, Frisk must travel across the underground to get back home. Yet when faced with the terrible truth of the consequence of their escape, can they truly find the will to complete their mission?

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.

Most Powerful Monster by thundersnake2375

I'm writing a fanfic on the popular game, Undertale. You fell down into the Underground at the age of 11, but little do they know that you had secret powers, at least until you got carried away. None of the pictures or videos belong to me.

Finally. They made it to the surface. But after an attack on the monster king, Undyne reveals a hidden secret that destroys the group. Can they bring themselves back together, or will their friendship break even more. (I suck at writing descriptions [~_~] )

The First Human [X Sans] {COMPLETE} by RaeTheStar

Imagine Undertale, but Chara never showed up. Chara wasn't the first human in the Underground. What if a glitch occurred, and you fell down instead? You fell into the Underground, but you cant remember your previous life. Now, you are surrounded by strange monsters, who have also never seen a human before. Will they let you live? [written 2017]

~Five Night's Of Unforgiveness~ by Bluefire20

Hidden things and Hidden lies. The truth of it all lies in one place. No one knows what happen, No one will. But Nothing is Unforgiving. Cover By Meh~ ((ps: I am really bad at desc))

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

Ok, I'm just saying this is going to be rough, a part three to my Undyne'in love because I can. (Warning odd ships lie ahead). Alphys is dead, she knows that. But then why is she still here? Why won't anyone notice her? Why? Alphys soon finds that only one person can see her, and he helps her in her life as a ghost. The two watch many odd things happening in the world they know. But soon when something happens to Alphys friend Frisk, maybe she will be the only one to save her. Read to find out.
