Après une route génocide, Flowey survie juste le temps de s'assurer le reset. Sans, ramené des ténèbres a gardé en mémoire la route précédente et décide donc de protéger son petit frère et les personnes qu'il aime de toutes menaces humaines. Mais y arrivera-t-il avec un nouvel étrange enfant dans les son sillage ? Et puis... Pourquoi cette enfant l'appelle "Gaster"!

Flowey thought everything was going to go right when he believes Chara came back, but when he had inadvertently summoned a real monster, things will probably go differently than imagined.

What if two humans were in the Underground at once? What if one human was DETERMINED to stop the other? What if they could both SAVE? What happens when an Unstoppable Force meets an Immovable Object? When a certain scientist pulls enough of himself together, he finally finds a way to stop the destruction of his world. (Undertale AU. Rewrite of DT.)

Two essences in one body, it was never meant to last. Two weeks after monsters' freedom, the unlikely cohabitation between Frisk and Chara within one body starts breaking down. Frisk's body pays the price while both of their consciousnesses slowly start blending together. As they become a kind of human amalgamate, the two begin losing themselves more and more with each passing day.

The End of the first arc is upon us!

DIRECT SEQUEL TO "PATCHWORK SOUL" — A few months later. A family of monsters and their little human kid try to start life anew beyond the confines of a giant mountain. Maybe they find something. Maybe they lose something. Time flows ever onwards, but sometimes it goes sideways, and it's heavier than they thought.

(This is a remake of the original What if) Down into the dark, Chara fell. Down into the dark, an experiment was run. What if she got to go home? But what if it wasn't to the world as she knew it? What if she was placed into another, at another time? What if that happened to be a version of Underfell?

This is an AU of Glitchtale, by Camila Cuevas. Enter the world of HopeTale as three monsters escape the grasp of the humans before the barrier is installed, and meet friends in strange places. For one of them, our main heroine, shall save them all with the power of the heavens and HOPE. The AUs shown in this AU aren't mine, but the AUs of my AU are.

Frisk falls in the underground at a time where Asriel and Chara are still alive and is first found in the ruins by the latter. Frisk being a human, Chara considers them as a threat to monsterkind, especially once they discover Frisk has the ability to go back in time and erase the consequences of their actions. Can Frisk show to Chara that not all humans are as bad as they think ?

An undertale AU where humans have stolen monsters' magic to power their machines, flowey also known as project FLWY, has tried to fit into a role he wasn't built for his entire life, will him meeting hen help him learn his true role?

It's Halloween in the Underground! Tricks, treats, screams, and magic fill the air, but for one human, he's feeling a bit left out. Lacking magic powers of his own to trick his friends, Frisk is in an odd position. Perhaps a spooky little DJ can help him out and give him the best scary night of his life!

The world of Avithan can be dangerous. Sinister figures roam the streets of Killmere-on-Sea, and the wildlands beyond hold treacherous secrets of their own. But for four brave adventurers, willing to face danger head-on for the chance to find mysterious, powerful artifacts, the world offers limitless opportunities! In retrospect, there probably should have been some limits.

Everyone knows the story, the story of how Frisk fell into the underground, made many friends, and eventually set the monsters free. But what if that wasn't the end of the story? What if there were someone who simply couldn't move on after the monsters were freed? Someone who's tired of being alone in the dark. Can Frisk avoid the consequences once again? Or is it already too late?

Taking place after the Neutral Run, it has been Fifteen years since Fisk fell into the underground. Now she is back and this time nothing will stop her from freeing the Monsters that have been trapped for so long, and if that damn flower tries anything then Frisk will make sure it has a very bad time.

Underfell AU. When dark memories of their time in the Underground intrude, nothing soothes Flowey more than hearing Frisk's heartbeat.

It's time for Luna to meet Muffet, but will she give the spider lady a chance? Gift story for paradise dazzleshine. :)

Eran las primeras vacaciones que se tomaba. Sans pensó que serian relativamente tranquilas, claro, si se ignoraba los gritos de su hermano, Papyrus, y el enamoramiento de este con Frisk; la molesta y deportista Undyne, intentando que se levantase del sofá y moviese el esqueleto; además de la familia Dreemurr, conocia a Toriel, pero sus hijos eran otra cosa. [Chara x Sans] [Chans]

We continue the Story in The Main Undertale Continuity… though there are some secrets the king would like to share…

This is my own story of Undertale. I do not own Undertale and I am not using others work.

Unwanted consequence of an experiment went wrong, prince Asriel Dreemurr finds himself reborn as a soulless flower unable to feel love or compassion. When confronted to death, he discovers himself a new power : Determination. The resolve to change fate. With the ability to travel through time and erase the consequences of his actions, the prince now held the power to play god.

The Underground, kind to neither human or monster, where adventures awaits and so much more. Join our chirpy protagonist as she braves this new frontier of excitement and peril with nothing but her wits and a sprinkle of magic. Rewrite.

At the end of the war, monsters don't have the choice : they have to join Mont Ebott for survive another day. Sans and Papyrus, forced to run away after the attack of their village, are delivered to the horror of the war without any help and this one objective. But as sons of the royal scientist, W.D Gaster, they are an easy target. Both of them start a dangerous journey.

Papyrus and Frisk share a peaceful morning together. Just a fluffy little drabble that's technically set in the Hopes, Dreams, And DETERMINATION universe but can very much be read alone.

The Underground is divided. Evil lurks in the darkness as hope slowly fades away. Only a human, a monster, and a dead prince can restore this corrupt kingdom, but not if it corrupts them first.

Wherein we find ourselves on the precipice of a deciding climax, yet presented with a denouement involving the practical usage of ascended training dummies.
