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!!!!

It's only been a few years since monsters have been released from their underground prison. In some towns, monsters are welcomed with open arms. Others? Not so much. Y/N is a 22 year old girl that lives a pretty simple life. Sleep, eat, work, relax at her daily cafe, go home, sleep. Then the routine starts again. However, her routine is thrown off when she keeps running into a skeleton, supposedly named Sans. She would like to get to know him more herself, but there's one problem.. He doesn't talk. Of course, Undertale belongs to Toby Fox, not me lol

You would think that with how shit your luck is, you would've been dead day one since falling into the Underground filled with scary monsters and a few spooky skeletons. However, much to your surprise, that did not happen (yet). You know how you ended up here, but you don't know... HOW. You're actually in the GAME Undertale now. And to make matters worse, there are some people who KNOW. You're surviving the best you can, but things are only going to get weirder from here on out. Gaster apparently needs your help? You're using the DJ to go to different AU's? You are gay now?- Okay, maybe that last one is just a joke, but still! You can only hope that your instincts are enough to keep you alive in these trenches. On God, they tryin' to drown you in this hoe! {Available on Patreon, Quotev, and Ao3 under GabrielXander}

The only way to the top in this world, this world born of war, born of death, the only way of ascension? ...is to become someone you don't want to be. And so I've got to break a promise. Because I've got a job to do. And there's no-one who's going to keep me from it. ~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~ How can something so enticing have such awful side affects? All the itching and the scratching from withdrawl keeps me out of check, I am fixated on all of the things that we were together, but those are fragments that are better off lost forever. (Crystalline- Gumi English)

You were an average kid, somewhat having a older mind than most of your classmates. you had always been into the undertale fandom, and even knew almost everything about the aus and soul colors. while what seemed like a normal day at school quickly turned around after a huge bang struck the class room next door. in this story y/n is nonbinary and 12-16 years old. But more interpreted as 14 I post a new chapter every 3 day and 5 days at the maximum. WARNING: this story will mention some forms of slight emotional harm. And Sexual abuse. Readers be safe. Please if you are in any danger, contact someone. You are not alone. With that aside enjoy the story . This story is finished as of September 1 2022, I encourage you to read my other story "Our Disturbing Love" And in the next month or couple weeks I plan on creating another bad sanses x reader.

(REWRITE OF THIS BOOK IS UP! It is called "Obsessive Love".) (I do not own the cover, Undertale nor any of the characters besides my OC's, they belong to their respectful owner. For some reason, I just see Error in the front instead of passive Nightmare.) Error, Forced God of Destruction and Destroyer of Universes was largely unknown unlike Ink, the Creator and God of Creation. Their fights were unseen by the AU's, none of the Monsters knowing about the Destroyer as Ink doesn't want them scared and Error gave no shits if anyone knew him or not. But Error's job is a complicated one, one that he is forced into, and he has to get involved to destroy the worlds. He doesn't touch the Original AU's, but the copies that Ink makes have to go. It was only a matter of time before something happened. Ink, in a middle of one of their fights, blinded Error, hurting him much more badly then ever before. In panic, Error ported into one of the Original AU's. Ink, fearing what Error would do, tells Dream about the Destroyer. Now the hunt is on for the broken, blinded skeleton. Meanwhile a blinded Error has been taken under the wing of another powerful Monster who has fallen for the broken Destroyer at first sight. But sweet love is truly beyond him. It is a obsessive love, a unhealthy love unlike any other. Nightmare would do anything for Error, and would do anything to keep him by his side as he goes about taking over all the AU's. Now to convince Error that he should be his and his alone.

"Do you not want to go back home? To the surface?" °°°°°°°°°°°°°°°° "No." °°°°°°°°°°°°°°°° "Why?" °°°°°°°°°°°°°°°° "Because my home is right here, sitting next to me." _______________________ You were used to the unfortunates of life. Everyone had them, it was normal, but life decided to take a lemon, freeze it, then throw it at your face. But, it wasn't like it was THAT bad... Until you fell into the Underground that'd been sealed for over a hundred years, of course. Friends along the way help you through the sudden changes in your life, and a bone-ified family as well. (82,110 words) (Undertale does not belong to me, only the characters I added for plot reasonings. You belong to yourself, of course.)

PLEASE READ BEFORE GETTING INTO THE STORY Description: Your name is (Y/n) and you are originally from an au called Dreamtale! Your life hadn't been the easiest however, but you were quick to always move forward despite this... Before Nightmare had become corrupted, you were his best friend and lover. You kept him from his breaking point, you maintained his sanity and most importantly... returned his love. One thing that is definitely important about yourself is that you are a selective mute... And your only desired partner for conversation is the King of Negativity himself... But what will happen once the true evil lurking within your lover drowns out whatever light he had left? What will happen when you discover that the Nightmare you knew was replaced by a monster that still somehow holds love for you? "And even with the evil finally in control of Nightmare, if both his sinister side and his old self agreed on something- then it would always be his priority... They both love her." This is practically my first story that I have ever decided to share online. It is quite a terrifying experience for me, so I hope that anyone who decides to read this will enjoy it. Anyway, I should probably inform my readers about a few things. First off, my primary language is not English, however, I will still be making an effort with my grammar! Second off, I will try and update this as frequently as possible... Even though I can get somewhat shy or concerned about how my work goes. Otherwise, all you will need to know is this: (Y/n): Your name (F/n): Friend name (E/c): Eye color (H/l): Hair Length (H/c): Hair color (S/c): Skin color (F/c): Favorite color Some things I will likely determine for the reader, but what is posted above will be the basics. Please also note that this story may contain some content that would be best for more mature audiences. Also, the cover image belongs to me, please do not use it without permission or steal it.

Gaster is the current royal scientist, set with a mission to break the barrier and free monster-kind from their underground prison. His loyalty and persistence to the task is clear, since he'll make whatever sacrifice necessary to complete it. However, even a perfectionist can be blind to some of their own flaws. Gaster has a habit of pushing things or himself too far. An accident occurs in the lab. Whilst trying to save him; one of his lab assistants, Y/N, gets injured. Burdening himself with even more pressure and guilt to fix it, Gaster thinks that doing all of her work for her will cover up the incident. Still, the sad reality is that the damage can't be undone. Well, Gaster ends up spending more and more time with her. As a result, both of them gain an entirely new perspective of the other, they aren't just another monster in a lab coat anymore. Hey! It's Oreo aka Writer~San! Undertale, it's characters, and it's fanart do not belong to me. However, the story does!!! I hope you enjoy it! (^w^)~

You've been doing the same True Pacifist / Pacifist Run over and over in a place called the "Underground". Though you like the Underground, you can't help but feel weary.. Every time you [SAVE] everyone, the World just..[RESETS]... And with that, you're back at the beginning again. You just want to go home... Why won't this "Underground" let you leave? ... Well, if you can't leave... Something 'new' should happen sooner or later, right..? (You hope that something exciting or different will happen in the Underground.) (You are filled with DETERMINATION.) --- ;) ~~~Disclaimer: I don't own those (MULTIPLE) pictures used in the Cover. I just mixed them up for a spicy cover. ( ͡° ͜ʖ ͡°) Mash-up covers are the best. ;') (I spent up to 3 hrs mixing stuff around editing adding light and shadows...*Dies*) If you have a problem with the Cover, I'll change it.

W.D.Gaster,the previous Royal Scientist,has been traped in the void all this time.However when he learns of Frisk and the destruction of the barrier,he knows he needs to help his fellow monsters survive mankind's judgement.But how? However,despite all odds,Gaster obtains something that may allow him to help save both humans and monsters,not only from themselves but from something else... Gaster got a hold of a Grey Human Soul.... Note:This will be a fanfic about the True pacifist ending of undertale.However,some characters will either be my OC or OCs by others who I will credit.All other rights of the characters go to the creator of the game,Toby Fox.Also this will contain major spoilers for the game so don't read if you do not wish to be spoiled.And lastly,a lot of the content is my personal headcanon,like the genders of the fallen children,so do not take what is said here as confirmed by the game. Now that we got that out of the way,i hope You Will enjoy this story and have fun while reading it!

Instead of you being a human, you're a monster in the Underground. I will continue to go back and edit or merge parts until I have completed the story. Parts that I am actively working on will be labeled "[under editing]" Also, art cover is an action figure off of fangamer.com. they have more action figure characters that are so cute. I am not affiliated in any way with fangamer.com. This is my 1st story in a VERY long time. I like to do things a little different as far as reader inserts go. 1. Instead of Y/N for your name, I use _______. Why? Because when I'm reading a story and read Y/N I think Y/N and then have to remember the name of the character I've made in my head, where as if I see _____, I immediately replace it with the name because there is no word for me to read. Love it or hate it, comment. I can be persuaded if the masses disagree. 2. I don't do H/C, E/C, etc., because it does the same thing that Y/N does for me. Instead, I will be as vague as I can on insert character descriptions giving the reader more freedom to imagine what they look like without forcing it down their throats. 3. For undertale specifically, I am more inclined to make monster!reader inserts, because that makes more sense to me. This will not always be the case. If the masses prefers human!reader inserts, comment so that I may be persuaded to do so. Also, feel free to ask for requests. The more requests I get, the more inclined I will be to do more stories. They don't just have to be undertale related. I will give you credit for any requests at the beginning of the story.

After becoming friends with none other than the guardians of the tree of feelings, you realize more things are going on than the guardians care to reveal. After attempting to help them you end up corrupted and your friends trapped in stone for 500 years. . . Currently rewriting!! This is a sans x reader fanfic so don't like don't read. Reader is gender neutral and there is 18 stuff in this book so please keep scrolling if you're under 18! So minors please avoid this like the plague There will be warnings at the beginning of chapters, if there's something I should put a warning for please tell me. Y/N = your name F/C = favorite color See anything else to put ill put it here /|\ ---WARNING--- This is mainly for fun and ideas put together from what my brain spews so continuity errors may happen and i will try to fix them accordingly. Again this is just for fun and nothing is really planned just improv to be honest. Still hope you enjoy! The cover was made by me

WARNING: THIS CONTAINS HIGHLY MATURE CONTENT (BLOOD, VIOLENCE) READ AT YOUR OWN RISK Money can change a lot of things. It can even change your destiny. Plunge yourself into a life of romance, science, disappearance and misunderstanding. ________________ "When you get better, I'd like to kiss you" ... Gaster only wanted to conduct an experiment. He surely didn't want his life to be taken over by weird feelings. He also wanted the only thing he couldn't really have. He wanted you. What will he obtain? Will his research finally be completed?

In the midst of Tokyo's bustling streets, you led a life that appeared ordinary, despite your role as a leader in a prominent gang. Yet, beneath the façade of normalcy, you carried the weight of profound loss-your mother, your father, your brother-all taken from you, leaving behind a void that seemed impossible to fill. Determined to shield yourself from further heartache, you resolved to protect the one remaining person you held dear: Frisk. Their presence brought light into your shadowed existence, offering a glimmer of hope amidst the darkness of your past. But fate had other plans. The dissolution of your gang shattered the fragile stability you had built, leaving you adrift in a world that suddenly seemed hostile and unfamiliar. Yet, in the aftermath of this upheaval, you found solace in Frisk's unwavering companionship, their presence a beacon of comfort in a sea of uncertainty. Then, in a cruel twist of fate, you lost Frisk. Cast into the unfathomable depths of the underground, your path collided with Aliza's, a chance encounter marked by the ominous presence of Horror Sans. Emerging from the shadows, his hollow eye sockets bore into your soul, his grin sending shivers down your spine-a chilling reminder of the darkness that lurked within the depths of the unknown. With each loss, the world seemed to grow colder, more indifferent to your struggles. Yet, amidst the despair and desolation, a glimmer of resilience flickered within you, a quiet determination to reclaim what had been taken from you, no matter the cost.

'When I was 13, I killed someone. By accident of course... It was the day I found out I possessed some type of power.' You kept it to yourself for years until one day it all went wrong. For your own safety you run away to the depths of Mt. Ebott in hope that the legend was true. But once you fell down you start to realise that this may not be the first time... "You've been here before, Y/N. And this time I won't let you run"

"What's that look for? Are you perhaps unhappy to see me?" "Oh no. Oh no, quite the contrary, my love. I've craved to be with you for the longest time" ***** You were sure that you would have captured a Monster, at all costs. But were you sure that you would have captured not a Monster's body, but a Monster's heart? ***** The Barrier is broken • Frisk has saved the Monsters • But not all things went according to plan . . . . ...... It is renowned that Frisk fell into the Underground. They spared everyone, they had [Mercy] for everyone. In the end, they have chosen to be an ambassador for monsters, to represent them in front of all the other humans. Frisk was full of [Mercy]. But the humans weren't as merciful as them. Humans completely forgot about Monsters, and now they had to deal with what they considered an ancient enemy, despite the Monsters' friendly intentions. What will Monsters do, if they suddenly are persecuted by Humans? Will they seek help? Will they search for old friends? ... Was it reality? Or was it a true living Hell? Things always went according to plan, so why? This time, why did it have to end like this? You are a spy, working for the most powerful secret Organisation of the Human Government. Your job is to find your targets and bring them back at the Organisation, but if you have the order to, then you have to kill them. This time however...you underestimated the enemy. ***** The new plan was quite simple: bringing him back in exchange for your freedom. Falling in love with him was not part of the deal though. ********* Word count: 110.473 Cover by Earth Garden on tumblr!!
