    Summary

    Papyrus... might have messed up.

    To be fair, it wasn't like he had a manual or anything for how to take care of a babybones (he'd looked, but had yet to find one), and Sans certainly never seemed to mind.

    Nothing even seemed out of the ordinary... until a throwaway comment by Alphys made Papyrus realize exactly how poorly he'd been taking care of his precious baby brother, and he was determined to fix it- whether Sans liked it or not.

    Summary

    A story following the first Sans; before anybody was freed, before anybody died, before ever meeting a human, before he got stuck in a time-loop and outgrew his big brother.
    How will he act when he has no idea what will happen next…?

    Summary

    It was a bit...ironic, honestly.

    He (was he a 'he'? or was he a 'she'? he- she- they- didn't remember the life before all of this...) was just a regular person, as so he thinks, he didn't remember much of his actual past life. Just that he was human and..just normal.

    He didn't really expect to die and reincarnate, again and again and again and-

    Well, his reincarnation just repeated, over and over and over and over and over....

    Well anyways, he found it a bit ironic. why? well, he'd never thought that reincarnation was a thing, and that he've been practically daydreaming about it in his past life.

    But he was envious. Just slightly, he didn't wanna be rude, besides, other people aren't experiencing what he's experiencing. If they don't know his problems, that's fine.

    That was fine, at least they didn't have to die so gruesomely or lonely everytime they die. And at least they didn't have to wake up, knowing that this was a new life and that the people around you didn't know you weren't yourself as a whole.

    That was fine, at least THEY didn't want to die one final time everyday.

    That was fine.

    Right...?

    Summary

    Papyrus was seventeen when his and Sans' father ...left. But that isn't too important. What is important is that monsters age slowly compared to humans. And while Papyrus is still the human equivalent of seventeen, Sans has yet to reach what the humans would consider two years old. With mother doors and human garbage this will be a wild ride. Please do not riot over the inadequate description if anyone has anything better please comment it.

    Summary

    “All the world will be your enemy, Prince With A Thousand Enemies, and whenever they catch you, they will kill you. But first they must catch you—digger, listener, runner, prince with the swift warning. Be cunning and full of tricks and your people shall never be destroyed.”

    ― Richard Adams, Watership Down.

     

    Chara was a freak of nature, a human born with the soul of a monster— one in a million, an unfortunate stroke of luck. It would only be fitting for them to end up befriending the one monster with the soul of a human and enough determination to force the timeline to bend to his will. Perhaps, with enough grit and resolve and a leap of faith, they can end up freeing the Monsters from the Underground, or die trying.

    Emphasis on the ‘dying’ part.

    Summary

    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.

    Summary

    The feeling, the sight, the smell, and the memory of rainfall on the paved streets was so bittersweet, now. He felt lost, terrified. His darkest secrets were still underground yet he felt as if the guilt of them trailed behind him and weighed him down the farther away he walked from them. This place he once called home felt so foreign now...It was as if the dirt itself had rewritten its history after his people's imprisonment, mourning their absence. But he learned, from his first step into this familiar world, that nothing was ever truly gone. Memories, the sun, the moon, the stars...even hate, violence, discrimination.

    But there were always exceptions. Rare ones. Like the one that stood beside him under the rain, and offered his soaked figure her umbrella with a kind smile; who looked at his hands with such wonder that his Soul churned in guilt and embarrassment as he quickly hid them in his pockets. He could only wonder why the spring rain's mist and her warm grin sent a tremor of melancholy and shame through his Soul.

    Summary

    During the Great War, humans drove Monsters underground. Not one remained above, and the years passed by fast, until the day came that the barrier was broken.

    Unbeknownst to everyone, there existed one single Monster who managed to escape being imprisoned. He was raised with humans for the entire time, at first begrudgingly accepted, and then honored as a magical seer.

    When the Monsters break free, what will he do now? Not a human, yet unaware of what being a skeleton could entail, he faces a destiny not even he could foresee.

    Summary

    A remastered retelling of my original story, "Why all the abuse?"
    Believe me, this story will be much better.

    Abuse comes in many forms and when it comes to Sans, he's experienced almost all of them. He can't tell half the time when someone's being nice or just pulling his leg.
    Regardless, this is a story about an abused Underfell Sans who falls into another universe. One full of comfort and no cruel jokes to accompany it. A place he finds himself loving more and more each day all while his brother is back home and is left alone for the first time in years with no one to keep him sane.

    'What if Sans never comes home again?' He wonders.
     
    Still bad at summaries, my bad.
    Also, don't let the first chapter's word count discourage you. The other chapters are 1,500 - 3,000 words each.

    Summary

    I turned back, I was so close to heaven already, but leaving him behind would definitely add the glittery bow to the rejection letter the angel is probably writing for me.

     

    I stole the Glittery bow expression from a comment Scribbly_Sketches123 made xd
    This was originally titled "Other side tunnel"

    Summary

    The human promises him that this is the last time they’ll reset. Sans doesn’t believe it.

    OR,

    ‘You count down each day that you’re here as if it will be your last, because you know that fate is guaranteed..’ - Sans attempts to live on the surface, despite ever-present fears of another reset. It isn’t easy...

    ...And someone is watching.

    Summary

    “THEN. CLOSE YOUR EYES PLEASE. DO NOT OPEN THEM, OK? I PROMISE THAT EVERYTHING WILL BE FINE.”
    “is this about… that thing? i thought it was a human, but…”
    “CLOSE YOUR EYES, SANS.”
    “where are we going? don’t you have to- to fight that thing?”
    “IT CAN WAIT. JUST. SO LONG AS THIS WORKS.”
    ...
    The newest brothers that have appeared through the frustrating machine are still a Sans and a Papyrus, but with a very glaring difference. The new Papyrus is the older brother... and his Sans is still a babybones.
