Doki Doki: Into The Multiverse by P_R_Official
8 parts Complete Mature
Join me as we delve deeper into the Alternate Universes kept within the "Into Madness" multiverse! Some of these AUs will not feature the full cast! Some will only contain one or two characters. //DISCLAIMER// These are only for fun. Some are completely original but most play off of already existing head-canons that i have for certain worlds and stories. Do not view these worlds as 100% my own. Also, the amount of worlds that appear in the multiverse do not match the amount of AUs that appear here! The ones that are here are just the big ones that are more noteworthy and some smaller ones that i thought would be cool to add. Enjoy! :)
Book 1: The First Fallen Human by carelesscreativity

(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!
Undertale X Reader [In Remake] by Cat_Maipie
13 parts Ongoing Mature
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
A Miscalculation In Space by Readern111
14 parts Ongoing
He knows he'll be dooming them if he falls, but he's tired, his body is breaking apart, held together on a higher being's whim only. He wonders if there'll be another to replace him. He wonders if there will be none. It's rather silly, really, since he won't even be around to witness that. The crowd, the rage and bloodthirst palpable in the air will ensure that. If he does not fall on his own, others will force him to. Or, in other words, the typical start of Error being forced to jump into the Void one way or another, in this case into the NaJ universe! The cover art belongs to irodimmatcha on deviantart(will take down if the artist asks me to)! Updates will be highly inconsistent.

Spirit of Bone & Metal (Undertale x FNAF) by BubblyShip
16 parts Ongoing Mature
They fucking reek. That's the first thing Sans notices about these animatronics. It doesn't take long until he notices other things about them, and after a lovely little meeting with the companies lawyer, Sans is blackmailed to keep working for the company. He thinks it'll be easy to collect some evidence and get the company to sink. It's... not that easy. With learning how to coexist with those who tried to kill him previously, every layer of the mystery he unravels only opens more and more questions. Sans is just trying to survive. --- Undertale x Fnaf crossover, updates the 1st of every month.

GlitchDust by adamabyss12

This is Glitchtale, but the beginning is different. Instead of Sans being his usual self, he turns into himself from Dusttale, where he killed all of the monsters and gained some of their magic. How will this affect the history of this fusion of 2 timelines, especially when Dust becomes a part of the outcome? And more importantly of all, what other surprises will wait for him when all is said and done, when he is finally through the huge torment? The pictures in the story don't belong to me. Alphatale belongs to Shadikal15, as well as the concepts he has made. https://vibeless15.tumblr.com
