Error404 is having a wonderful day in his multiverse! Error is actually keeping his criteria, Alphatale is going along well, Bill!sans is nowhere to be seen, and that DAMNED BASTARD INFECTED!sans isn't anywhere near him. Things couldn't be going better. But what's this? Where did he just end up? Who's this arrogant lady in front of him? And why can't he get back to his part of the multiverse? !!DISCLAMER!! I OWN NONE OF THE SANSES SEEN IN THIS FAN-FIC Undertale was created and is owned by Tobyfox Fgod was made by Harrish6 The art on the cover is done by @Rtaeing on twitter (check them out for amazing art like fr it's so good ^^) A/N I have no idea what I am doing.

You're Frisk's friend, who jumped down the Underground. Not wanting to leave him alone, you jumped after him. After a lot of pacifist routes and resets, you woke up in a place which seemed to be the ruins you knew, but soon you realized that you were wrong. You'll switch between different AUs, everytime something serious happens. Like a reset or you die. Or even something else happens? (Y/N) = Your Name (H/C) = Hair color (E/C) = Eye color (S/C) = Soul color (everything except red, becuase you're not determined) (F/C) = Favourite color This is my first fanfiction, so don't think too much of it. Even though, I don't think that anyone would ever find this. XD

This story takes place after the player vanishes from their fight with the bad time trio aka Sans, Shift, Stretch. The three got stuck there for a very long time until a strange occurrence happens which causes them to land in the world of Boku no hero Academia where lies a world of quirks with this world what will this trio be able to accomplish let's find out === Well.. i may or may not get lazy so.. Yeah this can be cringe and please be aware that typos can be basically littered everywhere and English is not my first language. Moreover, this book has really slow updates... Honestly I'd doubt that I'll finish this story...

As long as Classic can remember, he's always had feelings for Fell. He's not sure when these feelings started but he knows he would do anything for Fell. He swore to himself to love and protect him no matter what, but what happens when he reaches Fell's house and he's bleeding unconscious? The sight leaves him with two question, who? And why? Btw, Horror and Blue are another couple in this story. They have been a couple long before this story started. Let me know if you want to know how Blue and Horror became a couple.

This story will not have any sexual content..but then again i have yet to actually make a story containing sexual content as in a lemon or just plain out sexual/dirty moments in any of my stories but maybe i will in the future. C; this is my first Underswap Sans x Reader story but i'm putting a lot of work into for you guys so hopefully you will enjoy it. And i'm thinking about making a Error Sans x reader one along with an Underfell or maybe Aftertale Sans x Reader one if you guys want~ ;)

With the resets jumping back and forth, it seems to simply set the same path once more. However, this pattern breaks when the code seems to restart - and this time, there are a few more unfamiliar changes. How will Red react to the new MERCY filled Papyrus? And how will Honey adapt to the brother he loved continuously flinching away? Updates every Sunday!

Hi this is my first fic on here. I probably won't update it often. I'm sorry if it's really bad.

In this story Dusttale Sans is the only evil sans. The others don't exsist or are good. Dust was turned to stone for his crimes by the Guardians but managed to escape. Three years following his escape from his stone prison, Dust returns and will only relieve The Multiverse of his havoc in exchange for a bride. But who would be brave enough to accept such an offer?

Error is a glich , there is no question about that and because of that he is also verry powerfull to the point he can destroy a AU with one move . He was modified by creators that he can hear , the creators normally give them their unfinished world but when a curtain sanses with out AUs start going to other aus and they create new timelines Error has to fix that . -----------•------------ Error in this doesn't know about Ink , Dreams or Nightmares existance . In a away he is forced to destroy the AUs where people live in , he also can still get angry easily but he isn't insane as some might asume . But is he powerfull ? yes he is , even in his base powers he can over power a lot of sanses . And a lot of sanses in this multiverse aren't here cause they don't fit with my story like Error 404 like i don't need him here and he won't exist in this world . This is my multiverse so i give a few senses new powers they in cannon don't have . Only really bad sans is i guess Bill Sans , i might add few people to this list but most are just misunderstood . The creators are the most powerfull once in this world thats all i will say . The creators are voices only Error hears and no one else and his Power comes from them , he littererly cleaning their Mess cause creators are lazy to do that themself so they have Error to do that . Thats should say everything you need to know , now enjoy and remanber i am not native English speaker and please do not mansion Gramarly or Whatever that is .. i wanna learn on my own > .>

Chara is a young human who has decided to live in the Underground with her skeleton friends Papyrus and Sans. What will happen when she finds out that one of those skeletons is crushing on her? (An Underswap fanfiction) This book has lemons, dirty children!

I have a lot of random Undertale ideas I want to write, but I want to finish "Haunting a Reaper in Training" first, so I'll just write some here. I'll probably expand some of these stories in the future, but if you want to use some of them go ahead. Just let me know so I can read them! Warning: there are ships you may not like. Don't hate. That's all.

(Discontinued) This is a dust berry story Blueberry does remember the resets in his world but pretends not to know about it for Carrot (US Papyrus) to suspect thing's. ------- One day a skeleton wakes up in a forest, wondering what he was doing there he had looked around and just remembered that he was pushed through a portal by a skeleton he calls "Boss" for a prank. Soon the individual was found by another skeleton that was his enemy, soon he finds him self falling for the enemy but wants to keep it a secret from his friends brother. Will the brother fine out about this secret love and his brother's knowing about the resets and more or not.... ------- P.S. This is my first book, and their will be other ships in it too, the cover is not mine, the characters don't belong to me the characters belong to the rightful owners, and there is no sin in this if you were wondering

So I'm doing a DustBerry story- uhh It may have some... 18+, tho I'm not good at writing that in stories.*cough* maybe not- most likely not! I don't have the guts to make 18+ stuff. It's in a highschool timeline I guess. Not like Naj, I think that is like a type of AU where there are in school. BUT it isn't Naj, it's my own version I guess. Dust is male, Blue is Female- and some other characters Note, 6/10/2022; It's been like years. I read this at times, over and over. I can't seem to get an idea of what to do now. So this book is somewhat dead. I hope you enjoy what is available. I suppose people could attempt to continue writing it in another book of their own. It would be nice to see where the idea goes. I like the idea of it, but a shame I can't think of anything more. Maybe I'll start a new book if I get bored. Who knows what its theme will be. Thank you to those who have taken the time to read this. This story is my most seen one.

It all started when you fell down that hole. You met a new "father". Some new enemies. Some new friends. It seemed so great, but soon it'll all go downhill. Monsters disappear one by one. It's all because of your best friend. Your crush. The innocent one.

!WARNING! This Story Contains: - Manipulation - Brainwashing - Death - Violence - And an Insane Yandere Skeleton Info: Blue has woken up in the Anti void. He doesn't recall any past memories of his loved ones. He can't even remember his own name. But, an glitchy skelton may have the answers including the disappearance of his memories. And won't stop at nothing to keep HIS Blueberry from remembering the truth.

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)
