    Summary

    Papyrus wasn’t expecting to find another creature when he went wandering in the forest of Snowdin. He ALSO never expected to meet a human! As the Great Papyrus, he couldn’t just leave them to fend for themselves! Though...humans weren’t exactly...COMMON...in the underground..

    (A kinda AU where I try to imagine if Papyrus met a human WAY before the royal guard, before Frisk, before everything, when he is still an adorable baby bones! This is my first story ever, so I’m sorry if it’s ala suck.)

    Summary

    For Monsterkind, the Surface represented freedom.
    For Frisk, it's a return to some uncomfortable realities.
    It all began with a simple wish. When that wish faded, Frisk tried to move on.
    Except, 'moving on' was not so simple. Emerging from the Underground had put them in a worldwide spotlight.
    From an unknown child, they had become an icon of great value.

    'The Golden Quiche'

    What to expect from this story:

    -Mystery Drama
    -Anime
    -Extensive Surface Worldbuilding
    -Expanded History and Backstory
    -Magic System
    -More Magic
    -Both new and old people.
    -Feels.
    -Gambits.

    What to not expect from this story:

    -Toby Canon.
    -Commonly agreed headcanons (about a certain scientist in particular)
    -Slice of life. This is definitely not that.

    This work comes with its own magic science lore in the form of The Magus Compendium

    Summary

    Frisk Foster, a blind twelve-year-old girl, is thrown--or, rather, lands in--a world of monsters. In this land of "Kill or Be Killed," she finds friendship in the form of a tattered, bossy flower and the ghost of a long-dead child.
    Will she stick to her morals and SAVE the monsters of the Underground, or will she be sucked into the pit of fear and hopelessness and give in to the fear-inspired concept of "Kill or Be Killed" the denizens of the deep live within?

    Summary

    This is a side story I was holding on to but since I am completely redoing Beyond the Void I thought I'd share it with you all. I will update it once a week, on Wednesdays!

    This story centers around what if Vivaldi never met Gaster, what if there were no alternate verses, and if her family was not so squeaky clean as they are in the original story. Hope you enjoy it!

    Summary

    Counting up. Fifty. One hundred. Two hundred. How high can you go?

    Frisk has been running around the Underground for the past three days; he's been able to condense several years into them thanks to his inexplicable control over time. At first, it was an exercise in patience, a check to see what works and what doesn't on his mission to get back home. But something always seemed wrong. Trapped in the void at the edge of the Barrier with nothing but his phone, he would reset. And reset. And reset. Until finally he got it right.

    But by that point, the iron will to save everyone in the Underground was too strong to ignore. Do you know that feeling? Maybe you've felt it before?

    So he went back. And he went back again and again and again. There's got to be a way to save the one who matters. It'll take some time and some help, but there's got to be a way.

    Summary

    Consequences. Had you known there would be consequences, you wouldn't have done it. How were you supposed to know there would be consequences? You were just an oblivious god in a world full of oblivious gods, after all. You hadn't meant to ruin Undertale, ruin all the lives of your friends. Yet there you sat in front of your computer for countless hours, trying - and failing - to fix your mistake.

    It was a little game called OneShot that made you realize just what you were capable of, and now Niko might just be the only shot you have at saving Undertale. You've spent years planning and coding, leading up to this moment. And now, it's finally time.

    ~Updates (hopefully) every other Wednesday~

    Summary

    The Underground is a quaint little place. The Ruins, Snowdin, Waterfall, Hotland.. you were grateful to meet each and every monster on your journey, even if they absolutely had their sights on killing you at first. Though, despite the hospitality you've been shown, the laughs that've been shared, the spaghetti that's been made.. you wanted to go home. And your newly made friends are dying to go with you.

One who'll keep going, no matter what Frisk — or Chara — throws at them.

    So I ask you,

    What happens when an unstoppable force meets an immovable object?

    Summary

    This story depicts the struggles of the monsters after moving to the surface. The coldness they were met with and the problems they have to deal with after encountering humans. Mostly Sans and Frisk centered, it follows the evolution of Frisk growing up as an ambassador, and Sans' feelings and comfort around humans. Just like in today's society, we are having a hard time accepting anyone that does not look or think like us, we tend to isolate them, make them an enemy, judging on looks, race, ethnicity etc., in this case, the monsters became the race that almost everyone decided to label as enemies.
    ~I post one chapter per day! If i am busy the next day, i can post the chapter ahead <3 (super determined girl right here) Come join the fun ;3~

    Summary

    You live in a crappy part of town, your apartment gets broken into on an almost monthly basis but you're too poor to move and nobody cares enough to do anything. You attend college, one of the few colleges in the country accepting monster applicants. One monster is a short skeleton who, up until today, you'd been completely indifferent to. He's being followed by openly racist students. You're faced with a choice, save the skeleton from the gang of bigots or mind your own business?

    Your choice leads you down a path you weren't expecting.
