    Summary

    A collection of Undertale bits that aren't quite real stories (yet?). Some of them might be connected later and I'll make it obvious if that's the case. There will be a ton of different pairings.

    Warnings will be placed at the top of each chapter if needed, as well as the pairing of the chapter.

    Summary

    The barrier had been destroyed, monsters set free from their century-long prison. They had freedom at long last, and yet Monsterkind was slow to accept this truth. The idea of freedom after so long was almost surreal- But there were still the few monsters that wanted to go, to see just what their beautiful world came to become. After a long discussion between the great king, accompanied by his great advisor, and the officials of the cities closest to the great mountain that hid the monsters away, Monsterkind was given the opportunity to grow under the warm sun, within the safety of foster homes.
    But that is not all- The barrier dropping released concentrated magic back into the world. For those humans who descended from monsters, it poses an interesting problem when long dormant magical genes and cells are reactivated violently. Humans and monsters really aren't all that different.

    Book 1: Chapters 1-75.

    Summary

    I’m angry and so I’ll use this to poor it out. In this underfell timeline (before frisk) no one knows that Sans is worth anything. He keeps his magic a secret but with that everyone thinks his a “weak” monster and the only thing keeping him alive is his brother. Oh, and I changed up the language to better suit this AU. so there will be some curse words.

    Summary

    You like to think you’re a nice person. You’re always kind to the people around you. You like to bring sunshine into their rough lives, and try to keep a smile on your face despite the rugged times. You’re not even mean (most of the time) to the short skeleton who won’t stop teasing you, and you always greet his younger brother with a hug. You don’t even turn them in when you find out that they’re involved in organized crime, or even tell them you know for that matter.

    So yeah, you consider yourself a nice person. You know, besides the fact that you’re a serial killer.

    After college, you and your friends set out to look for a new place to live, hopefully somewhere familiar, with familiar faces. That plan gets scrapped pretty quick when you stumble upon a lively Southern city and its diverse population of both humans and monsters.

    Oh, and you're feeling pretty at-home in this hole-in-the-wall bar there. As well as with the bartender. He's pretty hot.

    Summary

    Sometimes the most unorthodox things are not so farfetched. Sometimes all it takes is a small shift for things to start tumbling.

     

    Being tossed into a world of monsters as if you were some kind of protagonist is something you’d expect out of a B-list horror movie. Or even Pixar. But it was your life now.

    That didn’t mean you had to be happy about it though.

    Given the chance to correct what's gone wrong, you swear you're going to fix all this even if it kills you. Which it probably will.
