the third child that was given to XGaster.

what happens if you were there instead of sans in 0.0 ? what would have happened if cross took a human soul instead? would it change the entire timeline of underverse or just... leave it as it is? would you die in a try to stop the x event, or ,will you fail? ...and most of all.. who are you? ------------------------ just an idea i had while wanting to see what would have happened if there was reader insert and there isn't a lot of those online.. beacuse all season 2 didn't come out yet I'm going to focus on season 1 trying to not get too lazy and discontinue the story if you like it leave a comment it would mean so much to me see ya in the fanfic Also, y/n is using all pronouns(didn't want to only do they/them, and is aroace(don't expect ships at all in this fic, it is focused on the story) yours truly, A_worried_Lily

What if someone from our world became dream on the first day they were made and were determined to not lose their brother to corruption like the original dream did in the story/game/movie? Even if they had to hurt the villagers to keep them away from nightmare they will. They will also protect nightmare, their brother from those who want to hit him. They won't be naive and hopeful like original dream. He would even pretend to be the guardian of negativity. He would rather kill the villagers then let then hurt his brother. Yet he still kinda failed and gets turned into stone but not for the reason one may think because Unknown to him nightmare notices his brother keeps getting hurt and finds out the reason for it was that they think Dream his the guardian to negativity. This end up with dream getting a protective corrupted goop of a brother. Well not what he expected but oh well at least he still has his brother. (Things will be different etc, including personality)

Y/n l/n, a monster that can copy the ability of any magic used nearby, is great friends with the one who freed him and all of his relatives from the underground. shenanigans insue

What if someone from our world died knowing a lot from the undertale and their multiverse/underverse? What if that person also knew about the balance and didn't creat too many aus? Also they dont like creating sad au's like flowerfell or places they end up like dusttale or Horrortale. Yes they did make au's and may have not known what to call them so they took some names that they knew and remembered from the movie/game/their world like horrortale etc. But they also kept a better eye or eye sockets on his au's and their originals.

Sans au's and all the characters of undertale don't belong to me, all credits go to the og's.

(So you know how we got Glitchtale, UnderVerse and The Villian Sans Squad right?. Well what if I were to tell you guys that the three seperate series were the three horsemen of the undertale Fandom. That means if there were three then there's a forth horsemen, working behind the scenes that had started eons ago. Well ladies and gentlemen, we have got The Multiverses Soul on stage so cue in the introduction and let's see where this will take us. Also I don't own Undertale or any of these Aus, I only own the storyline, (Y/N), some of the enemies and five of her star pupils that I won't reveal for spoiler reasons). "(Y/N) we need you, please don't go!". "....But you don't need me anymore". (Y/N) is the goddess of the multiverse. She started everything off by creating her own universe using her soul but it wasn't always like that eons ago. There was a crazed enemy that wished nothing but DESPAIR and CHAOS from the multiverse she's created but (Y/N) had evaded the enemy's plans by saving five monsters that became her star pupils. However let's not focus on that, (Y/N) had awaken in her home to realize something is wrong with her multiverse eons later. What is wrong you shall ask?, well let's find out. (Also events take place after Glitchtale, Underverse and starting of the Villian Sans Squad so yeah the multiverse is in jeopardy when you think about it hehe, enjoy😉)

what would you do if all of a sudden some small skeletons appeared out of nowhere one night and we're so small and helpless you couldn't say no to. So your living with small skeletons for the popular games/fandoms of undertale! you would do anything to keep them safe and out of harm, and they would do the same for you!

It has been 10 years since the monster broke free from the barrier, and since then monsters and humans live together in peace. But for some reason, monsters have somehow got a mini version of themselves, no one knows how or why it just happened. And for some reason, the skeleton bittys are popular because of their many different versions. You are a 19-year-old girl who lives in New York City in your apartment the problem is that you're all alone( if you're wondering if your family is alive, you just live far away from them), you have a small dislike for people. You wish you could get a Bitty to hang out with it, but the problem is that it costs a good amount of money. So you could never get one or so you thought until one day you find a strange box. This is my first time posting here so I hope you enjoy it! Also note there is some swearing. Note the cover does not belong to me. It came from https://undertale-au-fanon.fandom.com/wiki/Bitty!_Sanses By The Edit Lord Also I do not own any of the characters. Undertale belongs to Toby Fox.
