In Which You Become a Multi-Dimensional Pen Pal With Yourself by Idontevenknowwhatthisis
Fandoms: Undertale (Video Game)

Tags
Summary
"Resets", which you only actually learned about this morning, were a freaky time phenomenon which allowed something to travel to the past repeatedly. That "something" was a human, and that human wasn't actually human at all. That was what your journal explained to you.
(Or, Sans doesn't remember the resets, but he knows about them and he has to deal with it.)

Summary
Frisk, a child who previously gave up on living due to having a hard time on the surface, falls into the Ruins. After spending time in Toriel's care, they find the strength to go on. To them, this means they need to leave the Ruins. After facing their first death during a confrontation with Toriel, they address the elephant in the room (or rather, the extra human in their brain): Chara. Chara has no memories of their life and no motivations in particular, but as they get to know the other human kid that they're stuck with, they can't help but get attached. Frisk reminds them of themself, somehow, as if they were two sides of the same coin.
Together, they traverse The Underground in their now shared body, meeting foes, friends, and foes turned friends along the way. Despite having previously considered themselves good as dead (or actually dead in Chara's case,) they find their hearts crying out that they want to live, no matter what that ends up meaning to them.

Summary
Something is wrong.
You don't know where, why, or how, but you know something happened.
You can feel it, the claws that grab onto your skin, threatening to pull you apart and under to a world of the void.
The universe is screaming, you're screaming.
But you know nobody will come.Why is it that when something is so close, you still can't grab it?
Why is it so hard to keep one promise?
You're trying, you swear. But no matter what, you can hear it calling you.
You don't want to be alone, but yet it's better that way... right? -

Summary
Sans wakes up with a strange feeling regarding the latest Reset, but it takes him awhile to figure out why. Papyrus wasn't expecting the tables to be turned like this. Undyne just wants things to be simple and quick, what the hell? Alphys didn't know what to do with all of this strange acceptance... All because in the end, for Frisk, it really wasn't worth it...

Summary
This is the sequel of my work "How you SAVED me", so there're spoilers ahead for that work!
"Our final travel through the Underground was the best thing I've ever experienced. You were so relieved, so euphoric and excited. And there were so many funny, heartwarming and instructive moments that it's definitely enough for an entire new story."
Having received forgiveness for their previous genocide, Frisk has just reset the timeline once more (see the end of part 1!) Now, Frisk and Chara are on a mission to save no less than every monster, flower and other living being in the Underground. And they have collected all the necessary knowledge for that during the previous timelines. However, that still does not mean that things are always going to be easy.

Summary
There is a great difference in motives between doing a genocide after doing a pacifist route, and doing a genocide first.
Well, maybe not first. Death comes first.

Summary
"Happily ever after" includes a lot of fumbling and false starts. Chara and Frisk know this better than anyone else.
One of these days, they might even get it right.

How Do You Kill a Time Traveler by ZJFoster (toxicnuts69)
Fandoms: Undertale (Video Game)
15 Jun 2025
Tags
Summary
let me describe to you a hypothetical situation. you are a time traveler. you work in the business of space and time and whatever distortion that may be caused by any such anomaly. timelines jumping left and right and the space-time continuum would be bursting at the seams if this loop wasn’t trapped in its own bubble, making your job of discerning who being positioned where in time in space irrelevant and admittedly— a lot easier. your job is to do whatever it takes and whatever you can to shut this down, even at the risk of your own life. you just wish he wasn’t here with you. even though he needed to be. couldn’t he have taken the day off? you can’t help but wonder how many times you’ve stepped out that door.

Summary
Saur is a strange human, always has been, always will be. But her list of things that were on her 212X bingo card NEVER included finding a hidden civilization in a mountain that was not only still reeling from the last human to come down, but also ruled by a skeleton guy who doesn't really seem to embody the will of his people. Oh, and did I mention that her soul is deformed and never inside her body for some reason? Yep, this is about what you're getting into.

Summary
Frisk didn't want to reset. They hated having to do everything over and over again. On one run, the thing controlling them starts killing their friends... But they could persist and stop it... they hoped.
---Or, this started out exploring the fact that Sans was banking on the fact that Frisk would be in control when sparing and getting killed by him in the genocide route, but spiralled out of control into this.

Summary
Frisk's determination was a helpful, powerful gift... before it became a curse.
When a dangerous entity known as "The Player" takes over, Frisk is helplessly left at the mercy of a power much higher than theirs. One outside reality, guided only by an insatiable curiosity.
At first, The Player's control would muffle their feelings and force them back underground after they escaped. Very soon, the experiments and runs become much worse.
First it was death, then manipulation. There's always something new, unfound secrets to quench The Player's endless thirst for more.
Will it ever be over? We can only wait and see...

Or, Sans and Papyrus get a new houseplant.
