Greetings...I am {REDACTED}, I see you are interested in my newest experiment. I can't blame you, I too am curious as well. Come, let us watch a new story unfold, let us see how our subject will use his time in the Underground. Let us see if he can do the impossible, let us see if he can save something on the verge of collapse. Let us see if he can stop a genocide run...

17 year old frisk kind has a small crush on sans. the romance between the two and the nightmares of the monsters watching over them creates an unbreakable bond with each other.

I was a Soul without a home. Created by accident, but loved nonetheless. However, without a body, I was destined to die. Then, I was sealed away in a mirror by my own father, Asgore. Father said I would be safer within the mirror. Over time, my role in life became painfully clear. To answer any question without complaint...To love without being loved in return.

Read RESET Failure and Mindswept first. My Underfeelings AU. Chara and Frisk get into a fight while in Flowey's area in the ruins. Their ways split and Chara heads into the area where they both fell. Chara saw somebody fell. She went to greet them, but went into fear when saw it was Bane, a man on the surface who abused and tortured her. T for emotions and gore. I hope you Enjoy!

Goth child of Reaper and Geno gets written out of existence. somehow the one Goth survived a combination of all Goths, only able to survive in the anti-void. Well at least Error takes cookie bribes well, mind you others reactions to himself were amusing. Now if only the 'bad boy' Sans were not the only ones to remember him. Sadly Reaper not included in this group.

Frisk and Dr. Alphys figure out a way to give Asriel his real body back. After recovering his true goat-kid form, Asriel adjusts to live above the underground with his parents and Frisk. But as things seem to be normal in the town of Ebott, a malevolent force arises. This is a story of brotherhood, caring for your loved ones, and of course... DETERMINATION. True Pacifist timeline.

Cela fait six mois que Frisk vit loin de Nouvelle Nouvelle Maison avec Toriel, récemment promue première institutrice pour monstres et humains. Les grandes vacances sont l'occasion de renouer avec sa vraie famille, celle qu'il a sorti du mont Ebott presque cinq ans auparavant. Sans semble être le seul peu ravi de ce retour improvisé. Mais pourquoi donc ? Frisk décide d'enquêter.

[Fanfiction Undertale] A la fin de la guerre, les monstres, en partie anéantis, n'ont d'autre choix que de gagner le Mont Ebott dans l'espoir de survivre un autre jour. Sans et Papyrus, contraints de fuir après l'attaque de leur village, se retrouvent livrés à eux-même. Les deux squelettes vont devoir affronter le pire et le meilleur de l'humanité pour s'en sortir.

"let's stop pretending for a moment that you're actually human." Sans said dangerously. "even if i don't remember, i know what you are. you... human? heh. no, kid, you... you are a demon. those red eyes from my nightmares. your twisted smile. you're a freak. a freak and a demon." So yeah. He'll hold 'em accountable. "just this once." Just this once they won't be above consequences.

Frisk after saving the monsters form the underground is left with a big question; What now? What does life hold in store for her, she had believed that her fate was to die during the fight with Asgore so that the monsters would be freed. Now nine years later Frisk is about to hear the fates calling, would the answer lead her to ruin or could it be better than she had ever hoped.

Tell me my friend. A story as my eyes fall, one last story of how it ends, how it begins... and once its over let my eyes fall peacefully, and then when we meet again you can tell me everything new. "Well... it all began with a tear."

Sans has had enough. He finds Flowey, who now remembers true resets, and can feel again. They have to stop the megalomania,before it is to late. May end up being labeled a crossover at some point

When you look at a Stained Glass window or a Mosaic, what do you see? Do you see only mismatched pieces and parts? Do you see a mess? Or do you see the story they have to tell? This story follows the frisk of this world. She is one such mosaic...Let's call her Alyssa. Will her soul ever be whole, or will she break apart and vanish?

After going through countless timelines and experiencing hundreds of different happy or outright genocidal endings, Sans has had enough. After finally fixing the machine in his workshop, he decides to travel back in time to stop the choice that made everything spiral out of control. He had to stop Chara's buttercup suicide. M for mature themes and situations.

In Undertale, the monsters get their happy ending, but do they really deserve it? What if the humans found out about what happened to the other humans that fell underground? What if the humans learn what the monsters did to Frisk? What would happen to the monsters then? What will the humans do to retaliate against this injustice? Can Frisk stop this? Would they really want to?...

Long ago, two races ruled over the Earth: humans and monsters. One day, war broke out between the two tribes. After a long battle, the humans were victorious. They sealed the monsters underground with a magic spell. Ever since then, every human has been told that those who climb the mountain will surely die. But is that necessarily true?

We've made it to the surface, so... now what? A collection of one-shots following the events of GroupTale. Some may take place before they fell as well. Their kids also may make an appearance (in any chapter labeled "TNG") ;D. No context needed to read most chapters. Canon characters are included, but the main focus is the SOULS, Frisk, Asriel, and Chara. K plus

It has been one week since monsters have been freed from the Underground. Frisk then remembered that he forgot someone in Mount Ebott. He goes to get them when he finds out that there’s more than one person he left behind. When he tries to save the other though, they get into some trouble..

[contains SPOILERS] Asgore lost his kids. His wife left. He just sip his tea.

So in the last couple years Undertale is still a big thing and the creative community have had tons of inspiration. Especially in the AU department. Here Mako will be going through the various AU's and help those new to the fandom by giving the basic info anyone needs when checking out our favorite skelebros.

An alternate universe where the war never happened monsters and humans live in peace. The world is kept in balance by a select few who die and get resurected as the embodiment of a attribute they showed much of throughout their lifetime. Frisk wakes up one day with no memories other than her name.

Taking place three years before the events of Undertale, Snowdin Logs features a year in the life of the quiet town of Snowdin, as seen through the eyes of its author, Clive Wyrmstroke. (Hopefully updated every Sunday)

The barrier is broken. Monsters are free. Take a deep breath, because between securing monster rights, integrating into a new society, and reviving the lost art of magic there's a lot to worry about. Meanwhile Frisk and their ghost friend Chara realize exactly what is needed to revive Asriel: no less than seven human souls, all given willingly. Sequel to How to Save a Soul.

The star faded. The king perished. Then Dr. Alphys disappeared, having supposedly given herself up to the abyss. Undyne is now a despondent, hollow shell of her former self, with only one person left for her to fall back on...But from these dark ashes, can something else begin to blossom? And...What's going on in the Ruins? (Eventual Undyrus; this ship is ridiculously underrated.)

Frisk and co. gather in the park for an Easter Egg hunt.
