*UNLESS OTHERWISE STATED, I DO NOT OWN THE ART I USE IN THIS BOOK OR ANY CHARACTERS*

This one-shot book will have random short stories of characters from Undertale and other AU's. Don't know what an AU is? Alternate Universe. Don't know about them? Google them and search for their wiki page. Like I said before though, this book will have RANDOM stories in it. Most of it may be smut, and I'm sorry if that's not your thing. Just a warning for everyone, so if you don't like that particular one then don't read it. I will make sure that the chapters will have a warning just in case. 

I will be accepting requests from time to time so here I will have an 'X'  next to the current status. 
(X) Accepting requests

Transformers/Undertale Oneshots 😏😏 (Requests OPEN) by Sparky_The_Wolf

The lovely transformers and undertale working together as one. Just kidding, pretty much I love both of the fandoms so I decided to write some, I am always open to requests. I will do fluff and....other sinful things you people want. Another thing, I might be slow on updating just because of how life is. This is my first onshots/story, so please don't be mad if it's bad and please do tell me if I am doing stuff wrong. The stories will get better as time goes on, hopefully. Anywho, please enjoy. -Sparky (aka ME)

Soriel One-Shots (COMPLETED) by Mwendesa

READ DESCRIPTION Hi! This is a Soriel one-shot book! I haven't seen many in the community (I've only seen 1), so I've decided to make one myself! You can request anything except smut and stuff like that. You can also request AUs. Happy reading! UPDATE This book is now completed/discontinued. I've moved on from Undertale to a new Fandom. Thank you for reading and be on the lookout for my new book!

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

Undertale AU Oneshots (I guess this is considered Book 3) by The2tailedfoxy

heLLO. Since my two other Undertale Oneshots did so well, and I was wondering if Undertale is still relevant, I thought why not post a chapter, see if people wanna see chapters, and start writing. I've been in a good mood lately thanks to my Oneshot books and I thought "Why the heck not!?" Hope to see your guys' requests! (Also, I'll do lemons, smut, fluff, depressing stuff, whatever you like)

To Hell and Back (Gaster x Reader) by xsfolia

"What's that look for? Are you perhaps unhappy to see me?" "Oh no. Oh no, quite the contrary, my love. I've craved to be with you for the longest time" ***** You were sure that you would have captured a Monster, at all costs. But were you sure that you would have captured not a Monster's body, but a Monster's heart? ***** The Barrier is broken • Frisk has saved the Monsters • But not all things went according to plan . . . . ...... It is renowned that Frisk fell into the Underground. They spared everyone, they had [Mercy] for everyone. In the end, they have chosen to be an ambassador for monsters, to represent them in front of all the other humans. Frisk was full of [Mercy]. But the humans weren't as merciful as them. Humans completely forgot about Monsters, and now they had to deal with what they considered an ancient enemy, despite the Monsters' friendly intentions. What will Monsters do, if they suddenly are persecuted by Humans? Will they seek help? Will they search for old friends? ... Was it reality? Or was it a true living Hell? Things always went according to plan, so why? This time, why did it have to end like this? You are a spy, working for the most powerful secret Organisation of the Human Government. Your job is to find your targets and bring them back at the Organisation, but if you have the order to, then you have to kill them. This time however...you underestimated the enemy. ***** The new plan was quite simple: bringing him back in exchange for your freedom. Falling in love with him was not part of the deal though. ********* Word count: 110.473 Cover by Earth Garden on tumblr!!

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.
