Undertalefanfiction Stories

Y/n, who was a member of the army in her universe before it was destroyed and she was rescued into the Omega Timeline, has seen some really rough stuff. The Omega Timeline isn't safe in her opinion, but a certain someone left an offer to join his 'crew' for a "chance to do things the right way." -I know the 'Nightmare Gang' thing isn't canon, but we all love them too much to get rid of it. -Y/n is badass, not a pushover like I seem to find everywhere. -I will try to keep characters as close to their canon as I can, just remember that if I did that perfectly then technically none of this would happen anyways. -Warning that there will be mentions and even hints at things that can be triggering or make readers uncomfortable. I will leave warnings at the start of each chapter where these things are discussed outright, but this is your warning that there is some deep stuff that happened to Y/n. -Is it an x Reader? I don't know as of now so we'll find out together. -Swearing on occasion but not a ton. Usually just when mentioning things the characters are passionately upset about. Like Colin >:D -Title may change -Also I suck at writing fight scenes so beware -Rule of thumb in my fics: if you think I just made a reference to something, yes I did.

Encre and Fallacy have exactly what they want. Peace, and a good life set ahead. But, a faint howl, and echo seems to remind them of something...

As fragile as glass. The definition of one's soul despite the being stoic and cold. Even though you're the toughest monster alive, your heart is soft as a pillow.

"I volunteer," Isabella had said. "I will give Asgore my soul." Isabella had a dark and confusing past. She was hurt by her father, homeless, and worse. One day, she is kidnapped and brought to Mt.Ebott, where she jumps down a hole to end her life. But she lived. And now some man with a blue eye calls her Frisk and tries to kill her. And now, here she is. Giving up her useless soul. Sans hadn't seen Isabella in any other timeline, in his dreams, or even from books. Nothing. He just couldn't tell if she was trustworthy. But he also couldn't bare to see one more human die, he had given up leaving the Underworld years ago. So he begged Isabella not to do it, to think about it for a week. So she did. But as she is getting ready to leave, Sans begins to feel something strange about her... That was also when disaster struck... (No strong langue. Includes hints of being abused, but nothing too bad. Includes romance, battles and death. NO LEMONS!) #RebelWritings

While exploring Mount Ebott(which was one of the mountains that surrounded Gravity Falls), the Mystery Twins Dipper and Mabel accidentally fell into a huge pit, which led them into the underground where the monsters lived and roamed around. Will they be able to make it out alive without hurting anyone? Or will one of them slowly turn into a megalomaniac? ===================================== I DO NOT OWN ANY OF THE CHARACTERS ALL OF THEM RIGHTFULLY BELONG TO ALEX HIRSH/DISNEY AND TOBY FOX

What if the information of how to leave the barrier came a little.... earlier in the game? This story tells the tale of Mettaton and you, the reader (not frisk!!), going through various journeys together on the surface. Will he choose fame and fortune? Or will he choose you, instead? --- note: the mettaton pixel is by wingsandantlers on tumblr! check them out sometime!

Y/n possess a unique soul a soul even more rare than determination,Chaos. What will happen when he happens upon two girls who peek his interest?

(This is my first time writing a story in a while, so it will most likely have a lot of mistakes. This story is based on a story I wrote on Quotev, called "Baby Bones," as well. I'm hoping to change the story from what it was on Quotev and to hopefully have the motivation to complete it.) (This cover photo is the best art I could find to describe my character, except imagine the baby bones having red eyes and a blue fluffy jacket, similar to Classic!sans's jacket. I also imagine that he would have red freckles, too.) The main character in this story is the "Baby Bones." This little skeleton monster, who I have yet to name, has been thrown into an AU called "Underfell". He finds himself in the care of a monster called "Toriel". ATTENTION!! - If you have any name suggestions for this little baby bones, after you have read the chapters, please comment them, I'd love to hear your suggestions!!

Instead of being trapped underground,The monsters were cursed of never seeing the sun ever again. Hopeless and miserable from the previous war, they retreated back to their village. Unfortunate for the humans, the village of the monsters were near the road that leads to the city. With no more outside connection and a sudden loss of resources the humans became independent, building farms and factories. Although they can get out, whenever someone passes the tunnel into the wall of mountains, they never came back. Now a human child named Frisk with the help of their ghostly friend Chara will find a way to those monsters.Only then will they choose whether to kill them for the sake of the village or befriending them all and to make a new family of their own.

The timeline keeps resetting...nothing else matters but her brother; Luke...was what Jane ever cared about. "WHAT WOULD YOU EVER DO WITHOUT ME, MY DEAR SISTER...?" Luke's words repeated in her head as she took a sip of alcoholic ketchup from the bottle... On one deathly silent winter, a figure emerged in the fog...that, was when everything changed. . .

Frisk wakes up from a nightmare and finds Sans outside their bedroom door for the same exact reason. They spend a night talking it out, and Sans makes good on his promise to not suffer alone. A continuation of "Raise You Up"

The collapse of a timeline can be a life changing event. What happens to someone when they manage to survive such an event? What about the collapse of their entire Universe? Or their entire multiverse? What happens when someone survives such an event only to find them self in a parallel dimension? A dimension that reflects their own in many ways but is clearly not their home? What do they do? How do they move on? How do they keep moving forward, when they wake up to find that everything they knew was a lie? Everyone they loved is dead? Where do they end up? Where do they go? Welcome to the Crossroads.

Pharmacist prescribed drugs for themself and overdoses "You believed in me when nobody else did."

In a world where it is the law to take joy pills, puff is a reporter, who writes up the news and publish said writing to the public. Edge is a cop, who takes care of troublemakers or those that get off their pills. Puff stopped taking his medicine, he saw something disturbing in the paper that he shouldn't have seen. Now Edge has Puff under close watch after capturing the reporter. (Inspired by we happy few)

Well I've been reading for quite a while these crossovers where Sans (undertale) suddenly ends up in the My Hero Academia universe, so I decided to write one as well! Just wanna say that it's the first story for me to write, I wonder it will be even a little bit good. Anyway, enjoy reading! I do not own any of art used here! Same for Undertale and Mha! To understand this story you probably need to know the story of MHA, same goes for Undertale, though THE STORY WONT BE EXACTLY THE SAME AS THE ONE SHOWED IN ANIME/MANGA. Some of the incidents won't take place at all, so just to let you know, this story doesn't show the same story just with Sans participating in all the events that happened in MHA.

There were eight humans who fell underground. Minus determination, there were six. What happened to them? How did they get here? What happened to them after the barrier broke? Any art in this book will be original, please don't steal it. This is my first fanfic, so be nice! Undertale is owned by Toby Fox. (See original here: https://www.wattpad.com/story/272017662-minus-determination)

Mad Dummy possesses a dummy in the hot topic store you work at. Shenanigans ensue. Headcanon/idea from @stickfigurewar I do not own Undertale or its aus and this was meant to be a bit of a crack fic. Undertale is owned by Toby Fox. MC is unowned and mostly a self-insert Read at your own risk.

You're drifting... far away... in a world wet, unknown, and very dangerous. The dangerous, mysterous, Bermuda Triangle. Long ago, a storm meaning to clense the world of their sins washed throughout the lands. The fortunate humans believed the gods were infuriated with the monsters and began a menacing plot. When the storm clouds waivered, the water did not clear. The humans, vengeful and delirious with fear, declared war on the monsters. The humans lost the war. A godly being, however, came from the depths of the water and casted the monsters into an endless loop spell region of water. Welcome to the Bermuda Triangle.

I can recall the day, Mt. Ebott, the hole in the surface, and how it felt to fall. But I can also remember what it was like to be caught. I will always smile at those who managed to catch me. Our journey is about to end now, everything is so close. My demise, the king, the heat of flames. But I cant let any of them win, because deep inside I still have determination, and hope. Hope that soon, they can all smile with me.
