Being a doctor is quite a hassle, added that you're in charge of your family business. Now you barely have time for yourself, especially the chores around your mansion. You just don't know what to think about your skeletons friends who applied to be househusbands that your friends put up for jokes. ||GENDER-NEUTRAL READER||

this is going to be an edit and continuation of a story that I worked on in the 7th grade with a friend I had changed the sloppy mess that was the point of view to first person, which is so much easier, if I did swapfell or fellswap wrong I deeply apologize because I can hardly tell them apart

The Undertale Multiverse is collapsing. Monsters, magic humans, and those unfortunate enough to be caught are thrown in alternate universes; soul mates are meet in unexpected places; and soul leaches are everywhere. Humans are getting soul related illnesses and with monsters growing in numbers, Magic authorities aren't sure how much longer before humans strike back. But hey, we don't really care - we can read it all safely behind screens- Wait. What's this about being pulled into the multiverse? ******************* NOTE: Going through and editing, updates will be sporadic. Chapters edited: 4/9

Villain Sanses x reader story inspired by Phantom of the Opera A free Castle? Sign me up. (y/n) is offered a new home in a castle belonging to an old friend of hers but the creaking of floorboards and the sounds in the walls has you a bit paranoid. Is (y/n) alone in this castle? Or are there some Phantoms lurking the Castle's grounds?

this'll be like the first one but instead of Sane AUs, it'll be Payton AUs! The cover has Bone on it

Me rating undertale and their aus ships...this is my opinion, don't hate. If you have a different opinion, that's fine, I respect that.

You got stuck in another persons body. But their ghost is with you! You were told to go to the new highschool. You met skeletons! Then bla bla bla bla bla just read...

just some headcanons/ideas of how I think the different AU sanses and papyruses would act in a romantic situation :>

Pls read. I'm doing my best. I just want my ideas out there! When Nightmare's gang backs down years ago to raise kids. It's bin quite boring at the castle. Dream has also a kid and knowing that Nightmare hasn't bin doing nothing. It was safe for Dream to raise his kid. But recently Dream has gotten suspicious of Nightmare and has bin getting ready Incase Nightmare attacks. Well Night got an idea and.... instead of asking for his gang to come back. He took their kids. Art all by me. If I use someone else's art. I will make sure to credit them or at least say it's not mine and credit to the person that I have no idea who I'm crediting to. Game Undertale by toby fox. I never played the game. It all started bc of the comics and then the Au's 😭 The kids are my OC's while the au sanses in total (parents?) are not mine such as, Dream, Nightmare, Killer, Horror, Dust, Fell, Cross, Fellswap (or is it Swapfell?) Blue/Swap, Ink, and others aren't mine.

(As far as I know, no one has made a story about naturetale like this so..and the only reason why I writing one like this is because of fatal error part 5? Or part 4, go check fatal error out on YouTube if you haven't seen it already. This will invole the same names for lavender, thistle, and poppy, the others have the same names from other au's like undertale undyne, but I'll do it my way and possible personalities changes and thistle and lavender are twins in this story) also I looked up flowers and their meanings on google so don't get angry with me ok? What if...someone was reborn in naturetale as lavender? What if...other undertale au's meet naturetale from a complete different multiverse or universe? What if...they ended up in undertale original? What will the others think of them? And why is thistle, gaster, and poppy overprotective of lavender?

You'd just been fired from your job, but as luck would have it there's a maid position in a house fulls of Sans-es!!! Oh wait, no there isn't... But there is a position open for a house of Papyruses!!! This is a reader-insert fanfic, where the reader's gender is ambiguous. There will be more tags as things progress, as well as different Papyruses from other AU's; it won't just be three Papyruses the entire time. This is also based on House of Sans by Moontamble on Archive Of Our Own, so feel free to check it out!!! Cover made by cocodrawstuff on Tumblr!!! Go check out their art, it's really good!

Just headcanons about the characters of the different AUs. I do take requests! :) (LGBT+ Friendly!) And don't worry I'll have a proper cover soon.

Hi guys! First of all I should mention that the story pic isn't mine and of course Fellswap belongs to its original creator. A young hiker, Y/N gets lost and accidentally falls into a pit while stumbling in the dark. She wakes up to find herself in a whole new world that was never spoken of before except in children's stories. That's when she stumbles upon Barb (aka Mutt) and makes her first friend in the underground! But other monsters that live here aren't so welcoming.

Having little to no memories on what happens, you wake up to find two skeleton brothers who look awfully similar to yours. Confused and slightly disoriented, you later discover that you had been dragged out of your universe and into one that looks the same, except everything is Swapped Over. *Updated Description Average word count: 2000 to 3000. published: July 10, 2019.

This is for Oc's and Other characters please just follow the rules and have fun!

When Johanna is stuck in FellSwap, with no way to get back to her own AU, what will happen when she notices Raspberry Sans flirting with her?

Papyrus has a problem with his honey-addiction, and it's about time he stops before it gets worse. All attempts to better himself have failed, but all of that changes after he meets a real sweetheart. This is an Underswap/Fellswap AU that may include violent topics, fluff, and profanity altogether. This story was based on an RP on Tumblr back in 2016 (with some revisions). Read at your own discretion.

You didn't really understand what had happened. One minute you're taking a nap in the snow, the next you wake up in a house full of very familiar-looking skeletons from different games, You were already stressed out with trying to find out how you had gotten there in the first place, you didn't need the added stress of finding out that you were the soulmate to all of them coming in and facepalming you when you were already knocked on the ground. --- Rewritten because of plotholes and bad writing. (Black will now be named Razz to match fellswap)
