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
Existe uma história que todo mundo conhece, uma que não precisa ser repetida. Mas o antigo misturou-se com o novo, dando à luz uma obra composta pelo imutável e por aquilo que mudou. Oito humanos caíram. O primeiro foi perdido, assim como seu irmão. Mas último não era mais o mesmo. E um dos outros seis era um pecador. A história que todo mundo conhece ainda existe, mas mudada. Transformada. Não é mais a mesma história, mas, ao mesmo tempo, é. Medos antigos e memórias ruins transformaram-se em agressividade e raiva. Certezas e fé transformaram-se em dúvidas e receio. Uma jornada difícil transformou-se numa jornada ainda mais difícil... mas muito mais recompensadora.
E com tantas coisas iguais misturando com coisas transformadas, eu não consigo não me questionar: o que mais vai se transformar? E o que se tornará?

Summary
Or: The one where an adult Frisk wakes up after their funeral, back at the beginning of everything. Of course, they know how to navigate all their adventures underground, but... Does anyone want to tell them what kind of sin they committed? After waking up each time, in different timelines, some of which they even know they generated, and others that they themselves didn't commit? Yeah, this isn't going to happen (it happens anyway).

Summary
Monsters have been freed from their prison underground. They are finally able to explore and enjoy the world that humans refused to let them live in. Everything is going great!

He's a tough guy! Nothing can get through his sharp bones. Not even an unexpected meeting with a human, that leads them both to an alleway and... huh, Papyrus can't seem to remember what happened next. That can't be right! His memory is sharp and always relliable!
...
Why are his clothes on the floor tho...?
...
Oh god.------------------------
Papyrus meets a stranger that's going to change his life. Not for the better unfortunately. But he has a family that will always help him!
As long as Papyrus lets them.

Summary
Papyrus already knew that dreams and many words were meaningless. Still, that didn’t stop him from endlessly dreaming of things that would never be. Nor would it stop his cascading flow of words, should anyone stop to listen. But Papyrus knew that his words were idle chatter. They were crafted to make the few people he cared about happy and not worth much otherwise. And for the new people he’d meet, he’d put on quite a show of words for them. Because otherwise, he was quite forgettable, wasn’t he?
A character study, of sorts.

A FINE LINE BETWEEN ORANGE AND YELLOW by Fantasy_Artist
Fandoms: Undertale (Video Game), Original Work
09 Oct 2025

Summary
While Aneira didn't necessarily believe monsters existed, she did find the fact that everyone and their dog still did might mean something. Her childhood town of Beddgelert believed in monsters trapped under the mountains near their home that would need a seventh soul now to break out and destroy lands.
Aneira also knew that she needed to figure out what happened to the kid she was friends with who went missing. Which was how she found herself having fallen (probably) hundreds of meters below a mountain inside a cave system. Was she stupid for leaving without telling people where she was going, definitely, but, to be fair, she didn't expect to fall; she couldn't even see the hole.
Injured and wanting to go home, Aneira braves through the underground cave systems, finding MONSTERS both friendly and foes, learning about what happened to all the previous (children) HUMANS that fell.
tldr: Aneira falls instead of Frisk, is injured and is too stubborn not to use this chance to find out what happened to a friend (definitely dead by now, but she still wants to confirm), the Undertale cast feels like something is different, but not what. They also live in Wales here because why not?

a·me·lio·rate
To make something bad or unsatisfactory betterPapyrus has been hiding his knowledge of the resets from everyone. Well, everyone but Flowey. ...that should probably change.
Flowey needs to heal, but doing so is made extremely difficult when no one trusts you or actually wants you there. Besides your only friend, I guess.
OR: Papyrus and Flowey are besties who needs to Improve Their Mental Health™. Everyone else has issues too, I guess, but still. This is Papyrus and Flowey-centric so who cares/jSeries

Summary
Papyrus returns from training late one evening, and decides to ask Sans if he wants anything.
Sans is not there.
Papyrus shrugged it off, knowing Sans was probably at Grillby's, eating that disgusting, greasy food again. He was probably safe, drinking ketchup, telling puns and stories...
But Papyrus had a grim feeling that was not the case.
