× [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!

Secrets by SatanTM

Undertale AU... After the ordeal years ago. Frisk and Asriel started to date. They seemed happy and everyone in the kingdom loved them together. But when Sans, a well known funny guy with mysterious abilities who everyone loves starts to make advancements, Frisk doesn't know how to handle it. After the years of friendship with the funny skeleton she didn't expect this. But worse was coming and Sans knew it. Soon she's stuck choosing between the Sweet and Innocent Asriel and the Rambunctious and Frisky Sans all while fighting the worst opponent she's ever had to. (TRIGGER WARNING.) Suicide Self Harm Depression (Side notes) Frisk is a female in this so stfu with the complaining. I have to have at least two votes on the recent chapter in order to post another.

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.

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!!!!

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!!

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.
