    Summary

    Chara can't comprehend recovery anymore.

    ---

    After reseting from a genocide run, Chara can feel. Touch. Interact.

    This changes things drastically.

    And for nothing moreso than her mental state.

    Summary

    Reset. The power to alter fate.

    Determination. The power to overcome any obstacle.

    These are powers awoken only in the most determined of humans. And it is these powers that set this story into motion.

    Two separate lives, seemingly by happenstance, become tied together in ways none could have foreseen. Two separate stories, once having nothing to do with each other, become bound by strings even stronger than fate. And yet, as the darkness deepens and past tragedies are shed in new and revealing lights, these two sides may be the only thing that can stop a brewing plot that will lead to calamity.

    But perhaps, with just enough determination, not only may the world be saved . . . but the souls of those left behind might find salvation as well.

    Summary

    Alanna isn't one to listen to superstitious warnings; so it is unequivocally her fault that she fell into the bowels of Mt. Ebbot. Will she be able to untangle the complicated mess that Frisk, who is not exactly what they seem, has left behind to give the Underground the happy ending it deserves? And what is this darkness that's spreading into their world? Will a simple pacifist route do?
    Officially the Interfusiontale AU.

    Summary

    There’s a faint sense of warmth on your face. It’s so familiar that for a moment you’re back at the beginning, but when you open your eyes the lighting is all wrong.

    “Bet I killed Sans faster than you did.”

    Accountable? Accountable?!
    "let's stop pretending for a moment that you're actually human." Sans said dangerously. "even if i don't remember, i know what you are. you... human? heh. no, kid, you... you are a demon. those red eyes from my nightmares. your twisted smile. you're a freak. a freak and a demon."
    So yeah. He'll hold 'em accountable.
    "just this once."
    Just this once they won't be above consequences.

    Summary

    When the only other mage you knew came to you, you weren't surprised.

    When they told you that they had been missing because they had fallen into an entire world hidden under your own, you were surprised.

    When they told you that they had slaughtered most of an entire race, however, you were baffled.

    Sometimes it just goes like that.

    Summary

    Papyrus is just trying to get through his day in the human world. He's lost about everything he could possibly lose, and the only thing keeping him going are the memories of his brother. Humans gave mercy after finding out what occurred underground, and monsters don't have to suffer as they once did. Papyrus is just going to have to get use to things, well... until he ran into her.

    Literally.

    Summary

    When you tell someone to give up, you'd better make sure their idea of it is the same as yours. Because when someone feels trapped they can be driven to some pretty desperate things, things you would have never figured. Sans may have made a mistake somewhere along the way, but who could blame him? He just hadn't realized he couldn't afford not to care anymore. About this anyways...

    Summary

    When Nikki and Bucky live, the seventh soul cannot reset the timeline. They only speculate that it is because their determination is greater than Frisk's/Chara's. However they do not appear every reset, leaving Stretch, Red and Pupy in the constant cycle of limbo and heartache.

    Last time they appeared it was unlike the others.

    Stretch was romantically involved with Undyne when Bucky appeared and, in the process of trying not to hurt Undyne, almost drove Bucky to her own death.

    But now Bucky and Nikki are back. And something is very wrong with the world of UnderSwap.
