When Worlds come together by Honey_Bee669

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!
An Underswap AU: A Tale of Seven Book 1 by sabermoonlight1616
66 parts Complete
The Multiverse is vast, expanding continuously as more alternate dimensions are being created. Each world possesses it's own unique laws, stories and inhabitants. This world in particular, based on the well known Underswap Canon Universe, happens to revolve around three important questions. What if the first six humans who fell after Frisk never left the Ruins? What if the world is slowly succumbing to the corruption caused by the RESETs? And. . . What if Sans' cooking improved? A/N This is my own interpretation of Grouptale, in the Underswap Universe. Please read the Disclaimer and Warnings.

Remaster on my page - check it out! Sans has had an interesting past. A past that even his beloved brother barely even knows of. A past that he wishes could remain a secret. But when the questions start being asked, what does he do? These questions seem so little, yet they cause so much to happen. One little question. "Who is ??????" can change so much. A chain reaction from a single sentence can cause an entire world to crumble. Or maybe two. This is my first book so dont expect anything great. Inspirations: The "Better Times" trilogy by: @ANinnyMouse42 "Royal Blue" by: @dealialestine Started: 24th May 2021 Finished: 29th December 2021 A full 7 months of great fun with this book!

The human. It was all the human's fault. Everything I (we) gone through was all because of the human, so much resets, so much time stuck somewhere, so much Insanity. But now. Its different. 💣︎⍓︎ ◻︎●︎♋︎■︎ ♍︎♋︎■︎ ☞︎✋︎☠︎✌︎☹︎☹︎✡︎ ♌︎♏︎♑︎♓︎■︎✏︎ "THE DUST WILL FINALLY SETTLE!" "Judgement is inevitable, and you will face right here right now!"
