Warrior Cats x Undertale Multiverse Crossover
~~~~~~~~
Since the Multiverse was created, the Creators have been fighting over the AUs non-stop. It was a horrible, bloody war that lasted centuries. Many were killed and many were cast away as outsiders.

One day, the Creators met in an AU called Dreamtale, and after another battle, the dead came down from the sky as spirits, and the fighting ceases. They told the Creators that were alive to unite, or they would die.

So that's what the Creators did. They united. They- and their AUs inhabitants- created Clans. They all lived in Dreamtale, surrounding the Tree of Feelings.

Generations passed and the Clans had never seen a war so horrible since the War of the Multiverse. They lived in an almost-harmony.

Until Nightmare came along, that is.
~~~~~~~~
Hiya! It's me, Sighnerd.
This idea came to me in a dream, so I'm making it a reality. I love Warrior Cats, and I love Undertale, and I tried once before to merge the two, only that didn't work because I wasn't as experienced in writing as I am now.
You don't need to understand Warriors to read this! It'll all be explained. The only similarities are the fact that the Sanses (and some not-Sanses) live in Clans, follow the Warrior Code (which will be explained in the introduction), they aren't cats (that's just weird), they have the same roles (tweaked a little because they aren't cats), they follow the same customs, and some other small similarities.
Kind of a slow burn. That's what I'm going for, anyway.
There may be a few toxic moments, but it's Nightmare, so it's fine. Right?
Art and characters (except for the Empathverse Sanses and Sigh) do not belong to me! Neither does Warrior Cats. Cover art belongs to ProductionRoxy. :D
My interpretation of the characters, but I'm keeping it as canon as possible. They're tweaked a little to match the Warriors setting.All Rights Reserved

Y/N the Creator (Alphatale Fanfic) by DynamicCiocea

An Undertale fan gets reincarnated into the Alphatale Multiverse. Will they use the knowledge gathered from their first life to their advantage? Or will they perish, fighting against the Gods of Alphatale? The writing in the first chapters is pretty bad, but it gets better. Reader x SS!Chara in the later chapters. This is my first book and English isn't my Mother Language, but I'll try my best. This story takes place in the Alphatale Multiverse. It is not the same as the original Multiverse, so some things may be different. Published: 12 August 2023 Completed: 20 January 2024 I do not own any pictures shown in this book.

The Rogue Rebellion [Nightmare!Sans x Reader] [[SEQUEL TO FORBIDDEN]] by sighnerd

Warrior Cats x Undertale Multiverse Crossover ~~~~~~~~ None of the clans have seen Ash or the other rogues in years. Peace has settled among the clans, apart from the common small border skirmish. Nightmare and Y/N are expecting a daughter to arrive any minute. But there's always a calm before the storm. The eye of a hurricane. Ash is secretly planning his revenge, and when he comes, a darkness will fall over the clans like no other. Ash will not give up easily, and his band of rogues will fight by his side until their victory, or their death. ~~~~~~~~ Hello! It's me, Sighnerd. This is the sequel to Forbidden, so you should probably read that first!! I still don't really have drawings of ALL the characters, but I have some, so you'll have to deal with text descriptions until I have them all. If I find the motivation to make them all, that is. But I'll try to make the descriptions better and not forget characters one fourth of the way through the book haha. Again, you don't need to understand Warrior Cats. Everything is explained. I don't own most of the characters, but I own some! Nor do I own Warrior Cats. Cover art is by ProductionRoxy. Trying to keep the characters as canon as possible, but it's difficult when some of them- like Swad or Bird- don't have much information on them. But I'm trying!! It's easier with characters I own :]

UNDERVERSE by isimpforanimeboys1

!THIS BOOK WILL NOT BE UPDATED!FOR FULL STORY, CHECK OUT JAKEI ON YOUTUBE AND PATREON!

With the help of Ink -the guardian of the AUs- Sans will travel through the Alternate Universes to recover his soul while he discovers the origin of Cross and the imminent danger that will put the Multiverse at risk: The Overwrite button.

I wrote this in 6th grade, and I'm not very proud of it. There are multiple mistakes, such as me calling Underswap!Chara Frisk, and referring to X!Chara as they/them. PLEASE DON'T PAY ATTENTION TO THESE MISTAKES. THANKS FOR READING THIS.

Justice (Ink!Sans x Reader) [COMPLETED] by the_pacifist

Heya! This book will be a bit of a slow burn, which means that all the ~romance stuff~ won't happen until a little later in the story. ~~~ Twenty year old (Y/N) has sworn her undying loyalty to none other than Nightmare, one of the most feared villains in the multiverse. She's been working with him for years, since she was seventeen, but she's never encountered the infamous Star Sanses.

Her ultimate goal is to impress her boss and to prove herself to everyone who told her that she wasn't good enough. Will her wish change when she encounters the Star Sanses? Completed 12/24/2021 ~~~ Pronouns used in this story are she/her Disclaimer: None of the art used belongs to me! If you see your art/know the person who made it, feel free to let me know so I can credit them :) *Cover art belongs to RyuuseiRissu on DeviantArt*

Depression... A Sansest Story. by Undercorn1

Everything was running smoothly for the Star Sanses on this amazing day. Ink was drawing happily, Blue was running around chasing butterflies, and Dream was reading! Until we look a little... deeper. Dream was fine. But Ink was thinking about things much darker than his smile gave off. Blue, on the other hand, was thinking all happy thoughts! To an outsider. To anyone else, he would never have depression. To others, he was a cute little innocent boy. But only he knew the truth. Dream was the happiest out of the bunch. Not really surprised, are you? Let's check in on the 'villains' as you may call them. Dust and Cross were running from Killer, who was tightening his strings on his hoodie, NIghtmare was reading just like Dream, skimming over the page, Horror was playing with his ax, and Error was knitting. Who is depressed? Ha. You really are blind, dear, dear reader. Have you yet to notice that the strings were on Killers wrists, so they wouldn't show? Or the way Nightmare never turns a page in his book? Geno was running away from Reaper at that moment, who was laughing. Reaper was slightly sad because he had to reap some souls, but Geno was the one suffering. Fell was being beaten by his brother at that moment, and no one would save him... "You can't be saved without help." This involves Crossmare, Dustberry, Errink, Afterdeath, Kreme, and Scifell. No, I will not be using Horrorlust in this book because I just don't get the ship. Sorry Horrorlust shippers... I really got this whole sanscest thing from Bubblyship and __Purple_Fluffball__ so go check them out AFTER you read this. Please read... This is very depressing, as you can probably tell. 0-0

The Boy Who Doesn't Speak (Sans AUs) -- BEING REWRITTEN by SKSuperKitty

For some reason, Ink, the Creator and Protector of the Sans AUs, has decided that some of the Sanses of the Multiverse should go to highschool again. Honestly, no one really liked the idea, especially the Bad Sanses, including Ink's enemy, Error. Prince Nightmare is one of the AUs that must repeat these years of treachery. He basically only finished his actual highschool, and is NOT looking forward to having to do it again. Luckily his brother, Prince Dream, will be coming along the journey beside him. But Nightmare and Dream Are polar opposites, so Nightmare can't really get along with his brother's friends, nor Dream get along with Nightmare's, if he had any. With rules to follow and secrets to keep, Nightmare must go through highschool and not let slip the terrible things that happen at home. But then suddenly the two princes disappear. There's no trace as to who might've taken them, either. The only one that doesn't seem concerned is their own father, the king. King Sun-Beam. What is he hiding underneath all of those jewels and fake smiles? A/N: There is lemon/smut. So all you innocent people out there-- don't worry! Because I warn you at every chapter, and right before it happens. I designed the cover, but did the not the amazing artwork of Nightmare Sans. So credit goes to that person for the art. :D Update!!!!: This story is being rewitten. I'm making another book that'll just be this one but a little different. Once that's posted, I'll make another "chapter" in this one, giving a link to the rewrite. Thank you to everyone who still reads or checks up on this book. <3333
