There was once a Mania Hub Universe. It was a place where EVERYONE could go to and hang out with the AU's. It was just like the UT Universe, just full of AU's. And here at the Golden Flower patch, were the Portals to the AU's. Everything was calm and happy, until SOMEONE came along and threatened to kill UT Frisk. Then something even MORE strange happened. Find out in the Book itself Now!!

Murdertale by sansyboy11111111

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

Determination (Charisk) [OUTDATED] by AWholePerson

THIS BOOK IS BEING REWRITTEN ON MY PAGE! PLEASE READ THAT!!!! But if you want to read this one, I won't stop you. "I've carried this scarlet curse with me as long as I can remember. Maybe sharing it with you won't be so bad..." Highest ratings: #1 utau!!! #1 in ALL of Charisk!!!!! #226 in ALL of FANFICTION!!!!!!!!!!!! "Determination." Is a episodic story based on the events of 2015's hit game: "Undertale". Takes place in my Proem!Tale UTAU timeline. Be warned, for the first few chapters, my writing style isn't the best, as I have grown as a writer throughout the span of the book, and the quality of the writing gets much better as the story goes on. So keep reading, and your patience will reward you. This is a full-length fan-novel spanning the entirety of the True-Pacifist route of Undertale. So this is going to be a very long story, and this is only book 1. Don't expect to be here for a quick read. Trigger warnings: A lot. @Kae_Kae_uwu aka @kaelawrites2206 made the original cover art, go follow her! And yes! This is the same book! Just new cover art! Created 3-9-20 Completed 12-1-22 [VERSION 1 OF BOOK 1 OF 5]

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!)

- We are in it together partner. - Couldn't say it better. ============================================================================ Book inspired by au created by Rahafwabas. "Can you love someone that made your life a living hell? Someone like this can even love? Not knowing the truth behind it all it's easy to judge..." Action is taking place in Au (alternative universe) created by me. After a talk with Sans in the judgment hall, Chara reset the timeline however not everything seems as it should be. This way starts a journey that those two won't forget for the rest of their lifes. ============================================================================ Welp, here we go. Before we start I'd like to say that this is my first try to write a fanfic. I hope at least one person will like it.

Wait... I'm Nightmare!? I Thought I Died!? by Donut2460

(Cover made by me!) (!Updates 1-4 times a month¡) You died by cracking your skull open as you walked out of the shower. Godamnit life!!! To die in the most idiotic way!!! Which was very frustrating until you met a strange entity in the 'in between' that causes you to be reincarnated as Nightmare. Errr... sorta. What happens is that your soul merges with Passive!Nightmare and Corrupted!Nightmare, so they are now your buddies for life but in ghost form. God... kill you now (again), you never knew you were going to sign up for this when you died. ~Started Jan 19st, 2022~ ~Completed May 10th, 2023~ Highest rankings 🏅 #1- Dreamtale out of 1,000+ stories 4/19/22 🏅 #1- Dreamsans out of 1,000+ stories 5/12/22 🏅 #1- Nightmaresans out of 1,000+ stories 5/29/22🏅 #5- Comedy-drama out of 1,000+ stories 9/30/22 #1- Fandom out of 1,000+ stories 10/10/22🏅 #1- Aus out of 1,000+ stories 9/24/22 🏅 #1- Undertaleau out of 1,000+ stories 10/10/22🏅 #1- Reincarnated out of 1,000+ stories 9/30/22 🏅 #2- Guardians out of 1,000+ stories 1/26/25 THANK YOU SOOOO MUCH!!!

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: ???
