Summary
What if the player never existed?
What if instead of Kris, Noelle fell into that dark fountain with Susie?
What if Kris has no association with the Knight and knows nothing of the dark worlds?
What if the soul that was desperately needed to seal fountains was Kris's and Kris's alone, yet the human is blissfully unaware of how desperately they are needed? Of the leadership fated for them?
...
Kris watched as Noelle walked out of the classroom with Susie, sighing softly.
Whatever. Honestly...they knew they should care more but...Susie never bullied Noelle anyway....
However...for some reason after that, Noelle and Susie completely disappeared for the rest of the fucking day!?!?! And for some goddamn reason when they came back Noelle is randomly seeking them out and Susie is acting weird as fuck, and they're somehow a lot closer??? And for another unknown goddamn reason Susie WILLINGLY asked to do their project.
What the fuck is going on??????
Whatever. They don't need to be a part of this bullshit. At least Berdly is just as confused as to what the hell is going on with their project partners.

Summary
It was bad enough that Sans could remember the resets, but the kid had been doing nonstop genocides for a while now. It didn't help that after their latest reset the tremors started. Folks swore the mountain was caving in, luckily there had been no casualties. Sans hoped that if Alphys found anything in her and Asgore's investigation of the unusual tremors she would come to him
On a whim, he decided to check his timeline reader. Maybe the anomaly did something? What he saw shocked him: The resets had stopped (for now). He almost celebrated when he looked further ahead and his heart dropped; there were more resets and timelines than ever before. When he next saw the kid he was going to give them a bad time
Months later, Tori asked him to make a promise that he would protect any human that walked out the ruin door. Finally. The kid must have reset about 100 times just in the ruins alone.
The next day, Sans shortcut in the woods to wait for Frisk's arrival.
The door opened and a short figure walked out. Before Sans could "greet" the human, he caught sight of pink hair.
That wasn't Frisk. What the fuck?

Summary
Killer piensa que cada una de las decisiones que ha tomado hasta ahora han sido las incorrectas, pero aún así acepta el trato con el guardián de Au's, quién tiene la teoría de que el asesino puede redimirse si está dispuesto a cambiar.
Le entrega viales con la esperanza de que sentir algo nuevo lo motive a superarse y le regala un diario para que escriba en él.La historia está narrada en base a lo que él escribe ahí con excepción de uno que otro capítulo extra desde la perspectiva de otros personajes...
Intento apegarme lo mejor que puedo al canon de cada personaje...sus personalidades, ideales e historia, pero obviamente, por mera ficción, hay cosas que salen de eso.

Summary
A little bird flies the coop, clipped wings longing to soar, if only until she hits the ground.
Can she pick up the pieces her shattered heart and relearn how to live?Just, pure self-indulgence, really. Expect lots of fluff and shenanaganery.
My own spin on post-pacifist timeline. The monsters are free, but confined to one city, and kept secret from the world. A social experiment is run to see how humans hold up under long term magic exposure and if coexistence is really possible.
Our character, Robin, accidentally gets involved, and discovers a lot more than just magic as her life becomes increasingly intertwined with the lives of monsters of Mountainside. -

Summary
Nine strangers. One fall. A power none of them understand.
When eight teens and a young girl follow a mysterious light into Mount Ebott, they expect adventure. What they find is a crumbling underground world of monsters, magic, and ancient conflict. But that’s not the strangest part.
Each of them awakens with a glowing SOUL—a trait linked to their heart, their will, their essence. But these SOULs don’t stay still. They shift. Swap. Sync. And with every battle, their bond grows stronger… or more dangerous.
As they struggle to understand this new power, they’ll face old threats, cryptic warnings from a familiar talking flower, and a world that remembers the war they never fought.
They just wanted answers. Now, they’re part of something much bigger—and something down here is watching.
Welcome to the Underground. Stay determined… or get creative.

Summary
There’s a limit to the things you can do today. Accepting this is healthy. Thankfully, there’s always tomorrow.
It has been five months since the barrier broke, and Monsterkind was freed. Frisk is trying to make sure no one gets left behind. Some Monsters willingly stay behind, and others struggle to make the move. After some failures and successes, Frisk will begin to realize that getting to the surface is not enough. To save Monsters, no, to truly save everyone, it takes more than just a little sunlight to solve problems.
It takes risks. It takes knowledge. It takes patience. It takes friendship. And, sometimes, it takes someone else to help.
A post-pacifist ensemble story that focuses on Frisk still trying to SAVE everyone- monster and human alike.
