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.

When Nightmare said he wanted a group of monsters that would be loyal to only him and cause mayhem, he didn't mean four babybone brats. Now he has to take care of them while also trying to train them to become the perfect group of monsters that he wanted when they grow up.

Want to talk about falling into the wrong place at the wrong time? Y/N definitely scored big time on that one. One moment she's falling, the next she finds herself trapped underground with a monster that wiped out his own kind. He's a cold-blooded killer that never shows any emotion. Though, as time passes, she finds out that Sans isn't as heartless as he plays himself to be. Hello! Writer~San here! Cover art and Undertale AU/Characters aren't mine, but the story definitely is. I hope you enjoy it!!!!

Note to self: Never make jokes about getting reincarnated into a video game character because it'll actually happen. Welp too late to go back now, considering I'm already dead. Aka: Character gets reborn as Swap!Sans

Cold. Everything was cold. And dark. I was so alone... how could I have wanted this? This couldn't possibly be better than before... the warmth, and the light, and the smiles, however scarce. I cried out. I screamed, but it was muffled. I wanted it back. I wanted everything back. I regretted my decisions, my plans, my dreams. I wanted a second chance. **Reborn as a ??? Sans** !!READ THE FINAL ANNOUNCEMENT IN THE FIRST CHAPTER FOR IMPORTANT INFO BEFORE STARTING PLEASE!!

(I do not own Undertale or the picture, they belong to their respectful owners.) In this AU, Error never left the Anti-Void. Error never remembered his past or anything before living in the Anti-Void. Only knowing he was a error, what The Voices told him, and how to talk and sleep. He never met Ink, never had the need to destroy worlds. All Error had was the Voices. Nothing but screams of how worthless he was and whispering of how he should give up. In this AU, Error never became the Destroyer of Worlds. All he wanted was to stop feeling so lonely, to understand and belong. Error wanted to leave the Anti-Void. But Balance is needed. Error never became the Destroyer, so someone else would have to. In this AU, Fresh is more vicious, more violent. He can feel anger, hatred, and jealousy. Fresh became jealous of all the other Monster's being able to feel happiness, being able to feel love. To be loved. He wanted feel that, but couldn't no matter how he tried. In this AU, Fresh became the Corrupter of Worlds. Spreading his fresh virus across the Multiverse, possessing whoever he wanted, and turning worlds into a fresh paradise. All he wanted was to feel happiness and love, to love and be loved in return. To stop feeling so empty. In one world, their romance would have many hardships, but still stay nothing but sweet. In this AU, their romance becomes twisted, unhealthy, and dependent. In this AU, the Multiverse will tremble before them.

reader is transported into an old au they made when they were younger read as they go through there daily life in a new form and dealing with new but familiar faces p.s this is one of my first fanfics that I'm posting so if you have any nice criticism I'll take it p.p.s this story is not gonna have much angst it's mainly just for shits and giggles because I got bored and inspired(hehehehe -from future) inspired by the stores "reincarnated as a voice" by IHamTiredAndBored and "reincarnated as sans from inclinetale" UmbraM4un by two great stories that I definitely recommend and on that note enjoy
