Underswap Stories

Being part of a group dedicated to helping protect AUs against harm can take a toll on someone, specially if that someone is insignificant to his teammates. The self deprecation, and self doubt, can make the worrier feel unuseful to his team. And with the importance of the job it could make this regular mortal long for their old, simple life. Will Swap overcome his uncertainty of being a star sans and continue to help save AUs from those who seek to cause harm to them? Or will he resign his position and go back to being the 'regular' sans in his AU? (Art by Jael Peñaloza (Jakeiartwork on YT)

Monsters like you are the reason we will never be able to coexist peacefully. And for that, your end Must come. Is that all you have to say? I knew some of my creations were stupid. But you truly are idiotic. You are but a fraction of my creativity with none of my power.

[Cover art not by me - credit and love to the artist] THIS STORY IS BAD! IT'S OLD! Thank you all for the support, this story has taken me a long way, but I'm going to re-write it as an Error x reader! As soon as I finish the cover art, you'll see it on my profile. I love you all, and I hope you come along with me for the journey ahead!

In Underswap AU chara fully gained control in her body and stopped frisk to erase this timeline. she did a pacifist route and in end saved everyone.(includes MK too) Although frisk didn't like this after all she was filled with hate.

Ships; - Errorink/Errink (Error x Ink) - Dustberry (Dust x Blueberry/Swap) - Kreme (Killer x Dream) - Crossmare (Nightmare x Cross) - HorrorLust (Horror x Lust) Trigger warnings; - Self-harm - Eating disorders - Violence - Sexual scenes - Strong language - Mentions and suggestions of rape After ending their fake relationship, Ink and Dream's friendship is tense and unhealthy. It doesn't help that the Multiverse disapproves of their breakup, and Nightmare has grown stronger thanks to the negativity that stemmed from the event. However, things start to turn around after Ink and Error's 'friendship' takes a turn for the better as they realise their feelings for each other. But, what about the others? Will they eventually get together, or will their conflicting personalities collide with each other and make it impossible for them to get closer?

The swap brothers stubble upon not one but two other skeletons. Both in serious condition Who are they and where do they come from ? Underfell,Underswap and Swapfell doesn't belong to me or Undertale internally Also all art in this book doesn't belong to me unless I flat out say it And thanks to those who read this book the summary is complete garbage ~_~ But the story is better Hopefully....

The monsters are on the surface. Read, child.

After helping horror leave the bad sanses, swap sans takes horror to an au where no one can bother them and where they both can live a peaceful life for a little while. I want something different no babying!! he's not blueberry and blues probably the same height of most of the sanses in the multiverse maybe a lil taller not rlly idk Horrorswap. HORRORSWAP 🙇 Possible Errorswap in the future or swap x dream 😏 there was no proof reading whatsoever if there's a word that's spelled wrong don't mind it there's so much more errors that will happen :p I do not know how to write properly and I struggle to focus so the chapters may be super lame or out of character.

Questo libro sarà puntato a far presenti alcuni degli errori più frequenti nelle XReader, migliorandone quindi la leggibilità e la originalità. Mi impegnerò a portare almeno un capitolo a settimana, scriverò le storie Canon di tutti gli Au di Undertale, in particolare i veri caratteri dei Sans e darò inoltre vari consigli su come scrivere la trama di un libro incentrato su questo Fandom. Questo libro non è scritto a scopo di offesa. Warning: Parolacce

An Underswap Fanfiction. ×♪× This was it. The end. But why does it seem like someone was pulling you back from doing so? That you were meant to live? When you've finally made a decision to end it, something miraculous happened. As if magic, a certain monster came and took all the pain you felt with him. You've had a miserable life for as long as you could remember. But why? Why the sudden change of everything? The kindness. The peace. The love. The care. They were all there. In a place where you least expect them to be. But . . . something doesn't seem right. It's like . . . you weren't meant to be living in this world. ×♪× Sup, guys? This is the FOURTH BOOK to the series; GOOD TO BE ALIVE(1st), KILL OR BE KILLED(2nd) and I'M GLAD YOU CAME(3rd). If you haven't read the first three parts then please pick your ass up and do so. Sorry. I didn't mean to be rude. You might get confused in the middle of the series. I-It's not like I'm concerned or something. So, yeah. See ya.

So, this was my first book I made on here! This story is unfinished, and I don't make parts very often..But I still try my best to make the parts of some quality at least when I do! No sense in putting out a part just for it to be something like 10 words long, ahah- (No offense to anyone that may do that) Don't expect it to be professional or anything, though in my opinion I'd say it's a good start!

No lemon to be found here, but there'll be occasional suggestive content! This book is exactly as named - it's Sanscest one-shots! Cover art drawn by RuneTunnels on Twitter!
