A long time ago.. After the First and Last Overwriter Reset the entire Universe of the Underverse, It all went to hell.. 2 Parallel Universes were next to each other.. Undertale, and Kaiju Paradise.
One Day between the two Parallel Universes an Unofficial Overwrite took place which pull both of them to each other eventually colliding into one universe. Now known as the Experimental Universe.

The FUN Value of it is very random that every reset makes more genocide routes. And more Suffering.

Failed Experiments caused by Trauma..

And so The Error Overwriters, Nightcrawlers, and the rest of the Sans AUs teamed up to take them down.

The Timeline goes from 25XX to 30XX..



This is a mix of Kaiju Paradise, Undertale AUs.
This is not canon, it's just Alternative.
The Main Character is Nightmare Mode Sans.
The Overwriters, and Nightcrawlers are mine.
The Sanses and their AUs belong to their rightful creators.
The Slimepup OCs and Kaiju Paradise AUs belong to these people:

(Adult Lazarus here - I wrote this when I was like 14 years old. Forgive me.) Sometimes life gets to the point where you feel like you're a paper airplane. One minute you're soaring, feeling as if nothing could ever get you down. But then the next thing you know, you're falling slowly and nothing that you can do can possibly help you. You end up falling and crashing into whatever's below you and the heights that you had once reached. Then it starts all over again - becoming a vicious cycle. Someone picks you back up and throws you, making you soar yet again. But then they watch as you fall, not stopping you or saving you from the hard impact you meet with the ground. The process repeats itself over and over and there's no way you can stop it. After all, you're made of paper - you're delicate, fragile. You're thrown, you soar, you fall, you're picked back up, then it happens all over again until you break - becoming bent and broken from your head to your toes. Until you crash so much that you're ruined - then you're thrown away. At those times, you know that you at least have one person who will fix you. He calls you his queen, as any king would whilst in power of the empire you both strive to build together. This person is your home - your empire. - #6 in Quotes [03.12.21] - #2 in Sans [10.21.21] - Undertale does not belong to me. - Artwork/Music does not belong to me. - Also, I apologize for any of the spelling errors. I type quickly and so I do not really realize if I misspell a word or two. Sometimes I do go back and edit out the mistakes with spelling and such.

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.
