    Summary

    Your father is a poor man, who has a plan that might make him rich. All he wants is money and to make his small family happy, so he hopes the Aster family is able to make that happen somehow.

    But you fucked all of that up for him because of what happened at that party. Or at least, that’s what you thought at first.

    Little did you know, one of the members took a liking to you… he isn’t exactly happy about that. He doesn’t like attachments. He struggles to give you everything. Struggles to feel things in general, and usually locks his heart away.

     

    You just had to open the cage.

    Summary

    A family doesn't always have to be a mom, a dad and kids. Sometimes it's one mom and her kids, or one dad and his kids. Sometimes it's two moms, or two dads, or even more than that. And sometimes a family is three undead science geeks and two awkward bats.

    Summary

    Sans had only meant to retrieve a few things from the old house that had been forgotten during the move to the Surface. Getting ambitious with his ability to bend spacetime lands him in an unfamiliar Underground that seems to take his stubborn optimism as a personal insult.
    -----
    Sans had been minding his own business when an unknown skeleton suddenly fell into his life. He might have been able to take that in stride -- if the shrimp hadn't let his association with Gaster slip.
    -----
    Papyrus takes a monster in need into his home and hopes the decision will not be one he later regrets. His house guest appears to be a bit funny in the head but ultimately harmless, and Papyrus will admit his curiosity has been stirred with the abrupt discovery of a third skeleton.
    -----
    TL;DR It's a Swap!Sans in Underfell story.

    Summary

    Alphys creates a machine that can display a monsters memories and invites Sans, Papyrus, Undyne, Toriel, and Frisk to help test it out. Sans is suspisious but agrees to help. His suspisions turn out to be well founded when something goes wrong and they have no way to stop the test. To make matters worse the one person who didn't want his memories shown is having them played like a movie. Now the group is forced watching Sans' most important memories to the end but maybe it could be fate. Sans has been secretive far too long or are somethings better left forgotten.

    Summary

    Based off undertale characters, but does not have the usual monster-rise-to-power political plot.

    Our 23 year old Female MC is an optimist who does her best to care for those around her.

    She owns a small cafe, so how does she manage to afford her baby blue sports car and motorbike?
    She also has a little pet rabbit called Kiwi, and an indecipherable train of thought.

    Sans is hurt by all he's gone through during the time underground, but MC won't let him drown.
    He's smart, OP, and who knew he'd have a jealous streak in him?

    Who is this girl and why is she so crazy? More importantly, why does he love it?

    There is plot, but mostly fluff. Because I love fluff.
    Prepare for smiles and awwwwwwws.

    Summary

    Once upon a time there were humans, there were monsters, there was a war. But we already know about them. Surely that's a story that doesn't need to be told. So how about: Once upon a time, there was an Oracle, and there was an Elemental. Once upon a time, the Oracle had a vision, and it could only end with the Elemental by his side.

    Once upon a time, there was a book full of visions, and a spell to end all spells, during a war to end all wars. And there were two monsters who decided, by fate or by spite, how the war would end.

    Summary

    Dark, yet Darker.
    In spite of the invitation the Darkners and the entire kingdom received to join the above ground world, there are still a few left behind within the otherworldly caverns, lost, hopeless, or in Jevil's case, still locked up. Charlie, a representative for the rights and acts of monsters and the like, must find those who are left behind and bring to the light. Even if it breaks her.

    Warning: Spoilers! Lots of 'em.

    Please bear in mind this is a possible universe/AU/ending that I'm sure won't be canon due to the game being a demo. This will be eventual NSFW; no xReader for this storyline, maybe in the future if it is wanted. However, there are other humans here, too.
