    Summary

    You’re from the 1920s.

    A pair of boneheads had been with you every step of the way, out of the slums in the city, and into a life of organized crime and business deals.

    So when the skeleton brothers go missing, you may have freaked out a little.

    Just a little.

    They were your family.

    And you’d do anything for family.

     

    ... Including getting used to all this newfangled technology.

    And the fact you had traveled to an alternate universe about 100 years in the future.

    What the hell is a ‘smartphone’ anyway?

    Summary

    You write fanfiction.

    That's literally it. There's not much else to you. Besides being just another forum username amongst a sea of other users.

    You're decently popular, sure, and you love creating fantastical stories for people to read. The fandoms you currently inhabit give you that little spark of joy you need to keep pushing forward, but, once again, besides that small online presence, you have nothing, you ARE nothing.

    So what the fuck are you supposed to do when you wake up in an all too familiar place, with all too familiar faces staring back at you, saying all too familiar things?

    Fuck shit up and go off script obviously.

    Now you're meeting skeletons that are saying you're an anomaly.

    Summary

    An old professor of yours always said insanity was doing the same thing over and over and expecting a different result. You'd been trying not to think about it for seven years. Still, you pulled out your hair in clumps and slept with furniture pressed against the door. In a last ditch attempt to not be useless, you threw yourself into your university work, and by dumb luck found a subject that interested you and a lab partner who didn't care you slept in the office four nights of the week.

    A bachelors and a masters later, a letter comes in the post offering a research opportunity and a chance to shed your old skin. Looking to disappear, you accept, but what's done in the dark will always be brought into the light eventually.

    Whether you're ready or not is a completely different question.

    Summary

    As a human that's recently moved to the Underground, you've had a lot on your plate. The scenery's amazing, and you couldn't ask for a more thoughtful society to be in, but only a simple job's landed so far, and there aren't any close friends around yet. With all that going on, there's a lot for you to get used to... until, that is, you choose a comedy show over noodles one fateful night. On that night, you meet a dorky set of bones that just so happens to change everything.

    Summary

    You're me! Well kinda. You fall asleep one day and wake up in the underground surrounded by the monsters you have been obsessed with for the last 3 years. Now you've got to make the most of it while it lasts. You're going to take them all up to the surface! Even the little yellow flower.

    Ao3 won't let me add my own tags so imma write them here. Second person. I changed my name in this. You're called Delta now. I will take criticism but if you're just gonna tell me it's terrible and don't explain why, just don't comment at all. There's a little bit of sansby in this. You are 14 (not my actual age but I think it fits).

    Summary

    The Fallen Human and Prince of the Underground had a curious alliance. Nobody questioned it; Asriel had finally found a friend, and the King and Queen were overjoyed with their quiet, careful human boy. But a friendship built on lies, manipulation, and fear is inherently precarious, and Asriel is growing desperate to keep it alive.

    Welcome to the Underground. It’s eerily familiar for some reason? You don’t have time to think about that between murderous children and Sans’ accusations. You just can’t catch a break.

    Summary

    After thousands of unrelenting resets, Frisk has finally acheived it- the truly perfect ending. Asriel was saved, Chara was here and she even brought back the long lost W.D Gaster back from the void! With the help of everyone, they even got Goatdad and Goatmom to be together again! And to spruce things up, they all live in one big house together. Everything felt like it was to good to be true, just perfect. Everyone should be happy, right?

    Sans's night terrors has gotten worse over the past few months. The comedic skeleton avoided all of them to settle it by himself but his dear family was sickly worried.

    And so a memory machine was built, though Frisk had a baaad feeling about the turns of event.
