The tale of how two twins from Gravity Falls, Oregon fall down Mt. Ebbot, and experience what most other humans have never seen before, and now, all three books are in one place! DISCLAIMER: I DO NOT OWN GRAVITY FALLS OR UNDERTALE, ONLY MY IDEAS AND PLOT TO THIS FANFICTION. THANK YOU

Welcome to this story! ⚠️NO REQUESTS⚠️ But otherwise enjoy:)

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!)

This isn't a typical sans x reader(now papyrus x reader too). It's got more than that, well at least a different plot device first chapters will be about, just you(but it'll be good, I think so)and it's about you dear reader, you are now reborn as a Sans of a different au, but you don't have time to marvel how you're been reborn as your favorite character, because if you want to live you better focus because unlike frisk you're not coming back a second time when you die. (Short, and I mean short chapter, but this will ensure I can post more -w-) (Edit: this is context of your previous life is that you are originally female, aged 15, you had died during a car accident, you were sleeping in the back of the car, while you had a road trip to visit your family in Canada. The car had driven off the road because of black ice your father did not see in the dark of night. You heard the sound of your fathers scream then lead by your mothers then little brother's scream. You banged your head in the chair in front of you making you pass out, and when you open your eyes you had found yourself be popped out, but you didn't know that at the time. Art always be done by me. Edit: discontinued

After climbing down Mt. Ebott, papyrus's first stop is the local cemetery. He plans to dig up the bodies and infuse them with magic in order to find a Font that can wake his fallen brother or release Horror from their imprisonment. He is shocked however to find that all the bodies are missing! To make matters even worse, his stupid friends went and got themselves in trouble with a bunch of Fonts and now he and Flowey have to go rescue them before they get themselves killed. Can Team Cute Truth save everyone from the Fonts? Or is the real danger yet to be awakened? If you haven't read Fonttale, this won't make sense. So go read that one first, alright? Also this story is a Horror/Comedy and contains REALISTIC pictures not cartoony shit, so not only is the humor and story dark, but the pictures are made to make it look more like a movie than an actual book...like this cover art for example. That's what you can expect almost throughout the entire story. That being said, enjoy. :)

(DISCLAIMER: THIS IS AN UNDERTALE AU) Allow me to describe this in the simplest way I can. There is a fanfic-like covering, but with a much darker, twisted undertone. Sanscest, if that's what you're for, but also a juicy amount of story with it. Enjoy!

this is a love story between swap sans and the reader, the reader falls runs threw MT.Ebott trying to escape her twisted guardians when she is shot into a massive hole. Lost and hurt in an unknown place she is saved by a kind man who takes her in and treats her like family. Obtaining powers and learning about herself in the underground she uses them for good and helps get everyone out. Determined to help the people she Loves and holding onto her Hope she fights to survive and free everyone. this is my 1st Undertale fanfic and I wanted to start with underswap~ (if I get some things mixed up I'm sorry)

An Undertale AU i created... All the characters are overly aggressive(except Flowey) and try to kill every human they see. the last human to fall into the underground is Frisk, and they meet many monsters who initially try to kill them, until Frisk teaches them the benefits of being nice. this takes at the same time as Undertale, but is completely different. it is also similar to horrortale because that is the AU that inspired me. all the characters belong to toby fox The cover art was created by RenSabre

A story where you are roomies with the Au sons of sans. I dont really like introducing them again and again.Kinda like your harem..so uh good luck..lets see who you'd pick. *wink*

Y/N, meets a new coworker that changes her life forever. A monster, doing his best to make a living after moving out of the underground. Sans is this ecstatic, cheerful, absolutely innocent skeleton, smiling despite any given situation. However, Y/N finds out that Blue's wearing a different attitude outside of work. He's exhausted and working himself to the bone, using all he earns to pay for countless medical treatments and bills. He claims that they aren't for him, but keeps silent and won't give more details. Who's bills is Sans paying for and could Y/N find a way to help? **WARNING- Small Depressive episodes will be presented in this book. Read at your own consent.** Hello! It's Writer~San! None of the art/undertale au is mine, but the writing 100% is! Enjoy!!!
