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.

Become Mine And Mine Alone by harrish6
5 parts Complete Mature
(REWRITE OF THIS BOOK IS UP! It is called "Obsessive Love".) (I do not own the cover, Undertale nor any of the characters besides my OC's, they belong to their respectful owner. For some reason, I just see Error in the front instead of passive Nightmare.) Error, Forced God of Destruction and Destroyer of Universes was largely unknown unlike Ink, the Creator and God of Creation. Their fights were unseen by the AU's, none of the Monsters knowing about the Destroyer as Ink doesn't want them scared and Error gave no shits if anyone knew him or not. But Error's job is a complicated one, one that he is forced into, and he has to get involved to destroy the worlds. He doesn't touch the Original AU's, but the copies that Ink makes have to go. It was only a matter of time before something happened. Ink, in a middle of one of their fights, blinded Error, hurting him much more badly then ever before. In panic, Error ported into one of the Original AU's. Ink, fearing what Error would do, tells Dream about the Destroyer. Now the hunt is on for the broken, blinded skeleton. Meanwhile a blinded Error has been taken under the wing of another powerful Monster who has fallen for the broken Destroyer at first sight. But sweet love is truly beyond him. It is a obsessive love, a unhealthy love unlike any other. Nightmare would do anything for Error, and would do anything to keep him by his side as he goes about taking over all the AU's. Now to convince Error that he should be his and his alone.
Depression... A Sansest Story. by Undercorn1
57 parts Complete Mature
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
Expectations and a Golden Stitch-A DreamError/Insomnia Fanfic by HappyWriter62
50 parts Complete
Dream always felt the weight of expectations on his shoulders and they've only grown worse now that he's a Star Sans. Save this AU, rescue that person, stop Nightmare over there, and make X person smile! It's a never-ending cycle of tasks and he gets asked more about why he hasn't done it sooner or defeated his brother yet than thanked for what he accomplished. He feels trapped in this position and doubts if he didn't have his positive aura that anyone would care for him. Most like him for the joy he brings or what he can give them. Nobody around him ever feels genuine without a doubt in his head. Add in the stress of protecting one Star Sans(Swap) and keeping the other(Ink) from starting trouble and you have a positive guardian ready to break under expectations. Then you have Error, the destroyer of AUs. His reputation speaks for himself and builds all the expectations he needs whenever he steps foot into another AU. He's as bad an omen as a black cat crossing your path. Others assume he is bad because of his "freakish" or glitching appearance. He has accepted these but it gets tiring when he already has the voices bossing him around or Fate reminding him that he should do more destruction. But he doesn't limit himself to destruction. He watches UnderNovela, admires the stars, and appreciates what he can. He pushes the limits of what is expected of him or disregards them completely. A trait that Dream eventually finds himself admiring in him, the known enemy of his friend. He knows that Error's feelings are genuine since he doesn't change in his presence(still an angry manchild). So when Dream gets wounded and stuck with Error on a whim, where will it take them? Will it be a mistake remaining in a hatred of enemies or will it change them both for the better? Could this admiration open Error up to corrupting Dream or will he be the influence Dream needs to against expectations and live for himself?
