    So I am not that good with descriptions so here it goes. A Monster that Ink didn't create came out of a portal that Ink doesn't know where it leads. The monster started destroying AUs and Ink doesn't know how to stop it so Ink gathers up every Sans from the leftover surviving AUs and tries to get them to go through the closing portal and explore the new Multiverse to find a way to stop the monster. With Sans exploring the new Multiverse, the somewhat docile Error stays in Sans' AU to protect Papyrus from the Genocide run. *the cover isn't mine! It's MaliceAndMacarons, I just edited it!* *Also none of the Characters in this story are mine they belong to their rightful owners* *only this story is mine*

    A usual day,it was supposed to be when the ERROR!Skelebros began messing with the inhabitants of UT and UF.Brought on by their claimed boredom,they bring UT Sans to Underfell and UF Sans to Undertale.With this switch in mind,can either of the Sans survive in the universe they are placed in?And what will happen,should they both return to their respective universes?What could have or would have changed? .3. I certainly doubt their survival.Why?The feels policy,that's why. Also,there is gonna be some ships in this story and they are all non-con actually .-. If you do not know what that means,it means rape so yeah :/

    This is an AU for undertale in which all of the humans survive. I understand there is probably someone who already thought of it but this is my take on it and I haven't really seen a whole lot even remotely suggesting the idea. Basically what happens is during a true happy end something happens to make it reset all the way back to Right before the first child fell, and then the children start surviving

    [This is old & terrible. Read at your own risk] When a situation with a dying human ends up with you absorbing their soul, you panic (like any unprepared monster would). Suddenly Undyne is hunting you down, so you rope the mysterious skeleton next door into helping you. Which he does--in a very Sans way. And who knows? Maybe pretending to be his girl will pay off. | - Classic Sans x Monster Reader - Fake dating turns into real dating - One (1) very mysterious skeleton & one (1) very awkward reader - Papyrus is so sweet and innocent, I love him - Monsters really are in the wrong for killing children tho - I love happy endings and hate tension so expect an easy, relaxing read

    Aka maybe I would add some Kustard in here ( ͡° ͜ʖ ͡°) This is based on the fact that the books that I wrote are like films and movies, and that they were actually acting as both Sans and Red are actors. And they had a Q&A session! Highest Rankings: 453th in #ask and 251th in #underfell

    This is a book dedicated to perseverance's experience in the underground or stories that have to do with her. They probably will not be in order either. She is one of the six humans that fell in to the underground. You see me and my friends made ocs for all of the six souls the specific one we got is the one that we have the most of. Mine was perseverance so the character is the same age as me and has the same name. Oh and one last thing it does get feelsy so careful.

    UT Papyrus was just walking around, talking to his friends, US!Papyrus (AKA Carrot) and UF!Papyrus (AKA Edge), and they saw a really weird-looking tree with an aura that can't be explained. By the way, the category might be mystery, but this is also a comedy lol Also - laziest excuse in the book, I know - this is my AU, where UT Papyrus knows about resets and AUs. Hope you enjoy, as it's getting updated!

    I'm adding an OC character as frisk's daughter. yes I know that button tale has characters from under swap, but just imagine frisk in chara's place. in my version of the story, the button eyed papyrus is just as kind and sweet as he looks, he's just being controlled by error sans. please don't hold it against him. you don't know what he's been through. read to find out what happens. you'll be surprised what happens.
