Genocide. Last corridor. Frisk with a knife in his hands, and on the contrary stands Sans. Everything is as always, but according to the law of meanness, everything did not go according to the standard development of events...

Just a short Undertale fanfic story. This story was written by a A.I chat system that someone told me about!

The adopted daughter of the King and Queen of monsters, a young girl who can't handle humanity, both abandoned the civilizations of their birth species, lived a century apart, now they must work together to free the Underground and allow the monsters to see the sunlight once more. But will they be able to succeed, or will a certain flower stop them? Time will tell. Charisk.

"The little girl just could not sleep because her thoughts were way too deep, her mind had gone out for a stroll and fallen down the rabbit hole." - A life of fear is not what Frisk ever expected to have. - Warning: this is a dark AU that tackles mature themes and is not recommended for sensitive readers.

Luna has heard a lot about Grillby, but hasn't met him yet. Mettaton decides it's time for his daughter to meet the fire elemental who is her uncle. Done as a request for paradise dazzleshine. :)

For Monsterkind, the Surface represented freedom. For Frisk, it's a return to some uncomfortable realities. It all began with a simple wish. When that wish faded, Frisk tried to move on. Except, 'moving on' was not so simple. Emerging from the Underground had put them in a worldwide spotlight. From an unknown child, they had become an icon of great value.

Solo era café. Su hermano le habia pedido traerle esa taza de la cafetería que tanto le había atraído durante esos días, sin embargo, termino conociendo al Comediante. Como decía su hermano, "La vida comienza despues del café" [Sans x Chara] [Chans] - Actualización 14/02/2023, Especial San Valentin

The story right after Undertale.

Break of day, the dawn is here, Anny's up and pacing. Compromise or persevere, his mind is racing. Seems like two romantically inept dorks can't confess their obvious as fuck feelings for each other What happens when they can't bottle them up no longer? Doubletale belongs to XWolf26 and Mako belongs to XRabbit

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.

A household full of skeletons are competing over the attentions of one love. This isnt that house though. Unknown to the group secretively wrestling with their unpredictable love lives and universe-meddling machine, another house a few doors down has been gifted with its own skeleton posse clamoring for the attentions of their own little lady. A little old lady by the name of Mabel

Frisk is coming home after having been gone for a week. Papyrus can't wait to have her in his arms again. Just a fluffy little oneshot I wrote a while back and finally decided to post. Based on the Tumblr prompt "Reunion Hug."

The Rescue Arc continues with more suspense!

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."

Papyrus and his wife are watching stars.

(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?

A story about Katie and how she will trying to find Frisk and help her

Sans' threat may have not caused any problems with Frisk, but the human in front of him when he makes his threat isn't Frisk. Sans' threat caused a seemingly pacifist to reset into a genocidal timeline.

Sequel to "New School, New Meetings". Luna meets her cousins and learns that she has another aunt and uncle. :) Surprise story for paradise dazzleshine. :)

Kids are capable of sad thoughts too, and one of her imaginary friends is good at comforting.

All a little girl wanted was a friend, and so what if her friend isn't real?

"Might controls everything. And without strength, you cannot protect anything." A man falls into the underground and finds himself face to face with a demon. But he doesn't have the strength to beat them. In order to protect the ones he loves, he swore to do what ever it takes. Even if it means becoming a demon himself. (Based on XWolf26's DoubleTale)

Sans is always there when Papyrus needs him. Even if it's for something as simple as carrying him to bed after he falls asleep working in his lab. Just a bit of fluffy Underswap brotherly schmoop I wrote for my awesome friend Kaorukeehl a while back.

Luna transfers to Miss Toriel's school. :) Birthday/request story done for paradise dazzleshine. :)
