Ask and Dare the Sanses!!! (And Me- ) by Undercorn2

(I'm leaving everything as-is, but this book is old and strictly only still here for memory purposes. If you wanna read you can but it's really bad:P) Yeah yeah, another one of THESE books, yada yada. Just saying, this is not a normal book. Wow, so original right? I am obsessed with plots, so around 40-ish chapters is when everything just FALLS apart. Oh, and yeah... uh... be warned. DatOneArtKid and I-approve-this spams, and i reply to any comment. I will flip if there is another reader cause This is the MOST I've ever done and gotten this much. So like, just know. Oh, and ships........ Golly. You can ask to be shipped with someone, and i'll tell you if they're taken or not! Under is me, by the way, lol. Undermare. Bai! Oh uh... Welcome! I hope you enjoy your stay at the A+D hotel! ~Under~

A Strange Feeling (Sans X Reader) by Sak423

Do not expect consistent updates as life gets busy 🙃. This is rated mature because of strong language. You are a 24 year-old in college and have loved Undertale since the beginning. You enjoy all the aspects of the game; the story, the lore, the music, the backgrounds, and most importantly the characters. You've started having a strange, almost malicious feeling related to the Genocide run and that creeps you out. So, you start a pacifist run and after a while, you fall asleep. You wake up in Undertale and thus begin your new journey. Through your travels, the strange feeling comes back, but as a different emotion. Perhaps the only one that can help you with this feeling, is a certain punny skeleton. (I tried my best I'm not very good at summaries 🥲.) (Also I am so sorry for the kinda weird writing this is my first time writing a story. So I welcome constructive criticism.) Started: January 26, 2025 Ended: ???

Determination Of Others | RWBY × Seraphim Sans Reader• by TheKingOfToast

Hello! this is my first story so please don't criticize me and instead give me tips on how to be a better writer! anyways. (WARNING!: DISCONTINUED) You are Y/N Wingdings, and you are trapped in an eternal time loop of death and genocide so after getting tired of seeing everyone you care about die you decide to take matters into your own hands by absorbing the 6 human souls plus the one that put in this time loop, frisk. This basically follows the storyline of "the Thought" undertale comic but after your fight with Gaster an attack from Chara caused a rip in space and time sending you to a completely different multiverse. all the stuff I use in this story is not owned by me RWBY belongs to Rooster Teeth, and Undertale belongs to Toby Fox

The New Exchange Student (AU Sans x Reader) by OreosAndAvocados

⚠️ WARNING!⚠️ Viewer discretion is strictly advised! Dark themes such as suicide, self-harm, depression and others will be mentioned and some will be heavily descriptive. There will be foul language up ahead. And whole load of them. If things like these disturbs you in any way. Please proceed with caution! That's all! Thank you! ⚠️END OF WARNING⚠️ A SENIOR HIGHSCHOOL THING WITH DORMS!!! :D Yeah, I know, lame description. But I'm lazy. I assure you that the story isn't as lame as the description. Just... Don't judge the book by it's cover. Alright? Good. Now... ONWARD MY MIGHTY STEED AND READ ON!! :D ~*~*~ DISCLAIMER! I do not own any of the characters and AUs/ATs mentioned in the story and chapters! The only thing that I own is the plot and story itself! The reason why I chose to make this as "All rights reserved" is because if I put in "Public Domain" or perhaps "Creative Attributions" and etc, people will get the idea that they can edit this story of mine, or even claim it as their own. And I don't want that, I've gone through a lot of shit through me making this story overall. And knowing all that hard work will go to waste upsets me so fucking much dammit. Thanks for reading my rant n stuff. See ya. ~*~*~ INSPIRED BY MY HOMIE'S BOOK: "UNDERVERSE HIGH", so she was inspired by another peep's book which got ME inspired to make THIS book XD. Anyway, check her out! This is her profile; @Fanfomtrash

Grouptale AU - Undertale Fanfiction by aquanell

{Can everybody PLEASE stop reading this awful story so I don't feel bad about deleting it?!} This is an AU where all 7 human souls fall down to the Underground at the same time. DISCLAIMER: Several things I have decided on for this fanfiction. Toriel and Asgore got divorced after the death of Chara and Asriel and Asgore's declaration of war. The human souls will be called by names I have decided on for them, not by their soul traits. (Cody and Clover are from the fangames Undertale Green (Kindness) and Yellow (Justice) respectively. The others are Hannah (Perseverance), Amy (Integrity), Echo (Patience), and Leo (Bravery). Chara is a ghost only visible to those that remember (I'm going with Sans, Alphys, and Mettaton (since the latter 2 probably have their research to gain clues of the past timelines. I'm not saying they remember everything, but...), as well as Frisk and the other fallen humans.

Fifty Shades Of RED | Underfell Sans X Female Reader by darkpsychoangel87

You are in a contest to become part of the Undertale Multi-universe. The first part of the series, you are part of Underfell. Will you be victorious? Of course you will, or there wouldn't be a story. Find out what happens. If it goes well, or I can think of ideas I will do the other Sanses and Swap Papyruses. Note: This story contains: Sexual content, violence, swearing, and crude humor. Note: Also on my end, it says it only has 9 parts... there are 16... Well 15, one is an update.

Flowerfell Sans x Abused! Neko! Reader by Suki004

I made this book for @KawiiPotao6678 they have never read a flowerfell x reader so I made this book for them. But all you other people can enjoy as well. Sorry if some of the information on here is wrong I am not very familiar with the Flowerfell AU. I will look up what I can and learn more about it while making it. I will also fix what mistakes I have made because some people are so picky about spelling (not saying any names). I own nothing but the story!!!!!!!! I don't own you!!!!!!!!! I don't own undertale!!!!!!!!! I don't own Flowerfell!!!!!!!!!!! Nothing is mine!!!!!!!!!!!!!
