Summary
(Dustbelief rewrite, may differ quite a lot from the original comic)
Papyrus stares at his reflection on the river, willing his body to stay still and not look away.
His eye sockets are swollen, devoid of life; he also doesn't fail to notice how most of the scattered dust is located on his gloves.He took innocent lives with his very own hands.
Papyrus was not the same.

Summary
Your friend, Aloria, abandoned you-well it’s more like drifting away but she ghosted you for no reason- for her boyfriends even though you were the one who helped her through everything she’s been through. The one to comfort her when she bullied. The one to help her get of her toxic relationship. The one who let her cry on your shoulder till she fell asleep. But you aren’t going to fight for her anymore. You’ll just accept your role as a side line character in her story.
Until you found a creepy pair of skeletons.

Summary
“How much would it take for even the worst of people to change? For some, it’s for another to pull off the blinds over their eyes. For others, it’s for someone to beat the soul out of them.
Sans was faced with the former by a human who fell into the underground. Killing everyone there over and over again until Sans decided to fight fire with fire. Doing his own genocide route in order to finally stop the human in their tracks.
But once the human helped him take care of the true evil of all these genocides, they had a mutual agreement to be more…pacifist moving forward. And so, they RESET. But oddly enough, the RESET had Sans sent somewhere more…Sweet. But with fallen heroes trapped inside trees and darkness all around.
But the question remains, Will Sans have enough DETERMINATION to SAVE them and fight through the dark? Or will his FIGHT not be enough after all? But no matter the answer…He’ll make sure to have a FUN time…”

Summary
(Minha própria interpretação de Dustbelief, tem bastantes divergências do canon)
Papyrus olhou para o seu reflexo no rio de Waterfall, sua expressão vazia e sem nenhum vigor.
Ciente de como a poeira de monstros estava em grande parte aglomerada em suas luvas.Ele tirou vidas inocentes com as suas próprias mãos.
Papyrus não era mais o mesmo.

Summary
A human roommate of Sans, Kov. He decides to fuck with the machine that’d had brought his alternate versions here—instead of his attempt at helping speedrun the process of getting the others home he brought himself a twin.
They looked exactly like him.. Except for the fact they seemed a bit more feminine. And anxious. Very.
Now the skeletons have to send back another—which will set them off for longer and we also have the casual “Heather” stereotype but she isn’t dating all the skeletons quite yet. But she is targeting Kov’s alternate and making everyone hate her. That’s quite successful.
Kov n2 is starting to hate this world more than the one he originally lived in.
But then things get worse when you are also transferred from the world YOU stayed in.
Let’s see how long you’ll last.
(I made this for fun so it probably won’t make much sense,,, and it’ll be shorter and random..)

Summary
Papyrus hadn't been worried! ...Well. Maybe he had been, just a bit.
It'd been a while since anyone had heard from the human, so he called to check on them. But when a conversation revealed just how young they were, he realized things had to change. They were all on their own down here. And... They had nowhere to go.
Well! If there was no one else to take care of the baby bones, Papyrus would just have to do it himself!
—
Sans was trying to get through life and ignore the apathy that had settled over him for Papyrus’s sake. It was just so hard to care about anything when he knew none of it mattered. But when Papyrus had him bring the anomaly home like a lost puppy, things stopped adding up.
How could such a sweet kid be responsible for the relentless time loops?
—
Frisk was used to being on their own, and they were pretty good at taking care of themself. But—Well. ...Dying hurt. They just wanted to get back to the surface! With Undyne in the way, they were hopeless.
So when a phone call from Papyrus somehow ended with an offer for them to crash at his house, Frisk could only be relieved for the break.
They could afford to rest for a while, right?

Summary
“Not so fun being stuck in some loop right? Trying to fight to protect what ya got, not getting a choice in it. If I had the choice I wouldn't remember either.” The words oddly felt comforting. Link let out a slow breath, closing his eyes for a brief moment.
He didn't feel alone for the first time in a long time.
And that?
That was terrifying.
“To be honest, I kinda gave up a while ago. Just sat back and let the chaos go on, felt like nothing I did mattered anymore. Everything would just be reset anyways. Stopped caring what happened, that was until you showed up.” The skeleton’s eyes bore back into the Hylian.

Summary
Papyrus knew something was wrong with his brother—people didn't drop their HP Cap for good reasons, after all. But last he'd checked it was much higher than ONE. With terror in his marrow and his brother staying stubbornly silent about whatever was going on, Papyrus decided it was time to call in the cavalry, because he would be damned if he stood back and watched his brother Fall Down and Dust without doing anything.
OR
Papyrus realizes that being on the Surface hasn't helped his brother's crippling depression, because his HP is still 1. So he decides to bring the others in on his brother's stats to try to help.

Summary
Once upon a time many centuries ago, the world was ruled by two species: Humans and Monsters. Both of these creatures thrived together using their special talents to help one another. That was until the humans declared war on the monsters out of the blue. This led to the monsters to be banished beneath a mountain.
But rest well when I say the humans suffered their karma. Without monsters they soon lost their magic, along with their way of life. They developed their own powers called quirks, with this power came the raise of heroes and villains. Quirks were quick to spread until only 20% lacked them.
It wasn’t long before magic and monsters were reduced to legend. This led many to climb the mountain to see if the legends were true, only to never return. This was because of the heartbroken monster king who put a bounty on every human who fell.
When the last human fell, the monsters were ecstatic. Finally they’ll be free to wander the surface and feel the sun and the rain again! But unbeknownst to them, they have become even more trapped than they had before. With each reset the monsters were forced to live the same day over and over without anyone knowing ... .Well, almost everyone.

Summary
It was hard to explain, exactly.
A feeling. Walking into his room and his clothes not being where he left them, the bed messy and unmade. His favorite seat having a new indent in it. Mostly-empty bottles of condiments in the fridge, a spare pair of shoes by the doorway. A glimpse of bone as he walked up the stairs. His brother talking about things that Sans didn’t remember. Hearing people use his name for someone else.
A ghost living in their house.

Summary
Someone claimed that the principles of justice are chosen behind a veil of ignorance. But when it comes to the time to choose, can Sans make a just one?
He didn’t understand why he had done it. Standing in the freezing winds of Snowdin, with snowflakes swirling like silent witnesses to his hesitation, he came to the horrible realization that he never understood anything.
But now, under a blazing sun that cast no shadows, Sans would squint at the open sky and wonder if his choice had meant anything at all—or if it was simply another link in an unbroken chain of futility. The warmth on his bones did nothing to erase the cold from his memory. And he will, yet again, remember the distant day when he made the choice.
Snowflakes falling. Moments dissolving.
A sky too bright to understand.
