When Undertale Sans, Gaster, and Alphys discover a way to interact with the other Alternate Universes, they had no idea just what they were walking into.
It started with a theory, which evolved into a hypothesis, which turned into a plan. 
Now what started as a simple curious idea had transformed into a reality- a universe for the various Sans and Papyrus' that were unhappy. 
At least, that was the agreement. 
Sans had gone to Ink, (Inktale Sans) for a request to let Red (Underfell Sans), come to the Undertale universe to escape his brother, Fell. (Underfell Papyrus). 
When Ink refused, Sans came up with the next best option. 
Open, The Multiverse
But when you start up space-time shenanigans, even with good intentions, you never know what -or who- might come through to play.
Trouble begins to brew from the instant Sans brings the first member of the Multiverse to the new universe. But can Ink and the AUs stop the chaos? 
Or will it take one of them-
Then destroy them all?

**DISCLAIMER** I DO NOT OWN ANY OF THE ALTERNATE UNIVERSES. THEY ALL BELONG TO THEIR RIGHTFUL OWNERS. I JUST USED THE CHARACTERS FOR MY OWN STORY
SHIPS SHALL BE INVOLVED IF YOU DON'T LIKE DON'T READ! SORRY!

No Empty Promises [Ink X Error] FINISHED by ReaperK
31 parts Complete Mature
'It's all my fault...' 'Now he's gone...' 'If I would have listened, and believed him....' "I'm sorry," He let out a choked sob. ERROR cried, falling to his knees in his house. The ones he loved most were just taken from him. How could he live with himself? He left for groceries, and when he came back his greatest enemy he thought he killed a few months ago was in his house, holding the ones he loved. On the ground layed the one he loved, dying and becoming dust. "I-Im S-s-So s-s-O-r-RY..!!" He wailed out, dust laying on his lap. Nothing could bring them back, it'd take a miracle to find out how to revive a skeleton after he became dust. And it'd take forever to hunt through EVERY SINGLE AU to find the only ones he loved that were still alive. He LET him take them. But if he went and looked for them, they'd die. He took one deep, shaky breath as he wispered, "I'm sorry...." Then shock took over. Another voice just forgave him. Shakily, he turned around as tears stopped flowing. His eye sockets widened, and he started to sob the most he ever has. "HOW CAN YOU SAY THAT?!" "I LET YOU DIE!" "DON'T FORGIVE ME!!" "I LET HIM TAKE THE TWO AWAY, DAMMIT!!!" -WARNING- Rated R/18+ for Violence, Swearing, and suggestive content. CONTAINS: Deprsssing things, murder and gore, sexual content and more. READ AT YOUR OWN RISK. Cover art does not belong to me, only the storyline and ERROR's kitten. P. S. THANK YOU FOR AAAAAALL THE READS, LIKES, AND FUNNY COMMENTS. IT MEANS A LOT, YO. ~RK
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

I've seen some Undertale fanfictions where readers and original characters are sucked from our reality and transported in to the reality of Undertale and it's several aus. I got inspiration from some of the stories, I don't exactly remember the name of the stories I apologize but I give credit of the original idea to who ever came up with it first. any how, instead of the character staying human, once they are transported they're turned to skeleton, so the magic in their body can get use to not only the transfer through the void, but so their body can be use to the magic drifting around in the monster world. cover art is made from a picrew dress up/make a character site. all credit to the creator of the picrew! slight trigger warnings for those in need racism towards monsters harassment transphobia homophobia slight panic attacks here and there onwards to the story!
