    Summary

    Sans tries to act like his old self, but the damage the resets had caused was inescapable. It doesn't help when you know it's only temporary, lives solely under the control of a young misguided child. (Intense gore warning)

    Summary

    A half dead skeleton calling himself “Slim” shows up at Sans’ front door seeking asylum. What's worse is that the monster he’s trying to escape is an extremely deadly version of himself. With the attention of this “Razz” now looming over his own brother, will Sans be able to protect the most important person in the world to him?

    Even with the help of two other Fellverse skeletons, the idea of saving Papyrus and the universe he calls home starts to look more and more forlorn.

    Summary

    Gaster notices things, but doesn't want to admit that something is wrong. Sans has been going through a lazy streak, nothing more- right? Though perhaps behavioral issues aren't the only thing wrong with his oldest child.
    ---
    An AU in which Gaster doesn't fall into the core, and is Dadster to our favorite skelebros. Sans has nightmares of alternate timelines/universes- and is spiraling out of control.

    Summary

    What starts off as an eye appointment at Alphys' lab turns disastrous when the skeletons start messing with her equipment. Now they may have accidentally created a bunch of mini versions of themselves. Of course this can't be that big of a problem... right?

    Summary

    A bunch of unfinished ideas centered around Classic!Sans. Some chapters will be one-shots, notes, or just summaries of unwritten stories. Majority will be angsty, dark, and/or graphic. Lots of one-sided and/or abusive shipping.

    Ch. 12 – One Thing to Another
    After college, his brother scores a career as a cooking show host and loses contact with him. Sans barely manages to pay the bills as a janitor at a local public school and a weekend housecleaner. His situation is stable and rough but he manages just fine. At least until a mirror-image of his brother finds him online and requests he clean their house in a prestigious neighborhood. Things spiral after that.

    Summary

    Sometimes Papyrus wonders if the memories are even real, or just fabrications of his mind to fill up the already numerous holes.
    But he doesn't think even his mind could conjure up the bad timelines.

    Sans has never really been able to doubt. He simply takes note, learns. Moves forward.

    Whatever the case, they have a job to do.

    Summary

    “WHAT ARE YOU LOOKING FOR OUT THAT WINDOW?” The blue asks.

    “Freedom.”

    “FREEDOM FROM WHAT?”

    Edgy opens one of his sockets looking the blue bitty over. They’re so stupid. Does he not realize he's in a cage right now?

    “From this… all of this.” Edgy waves his hand around in the air.

     

    This is a bitty story about three bitties who escape a shipment truck and end up on an adventure. Eventually finding a home, a friend, and a horrifying bitty they can only imagine understanding.

    Summary

    FELL AU
    Most would tell ya that the guiding role of this world is kill or be killed. But that's not really it.

    The real rule that Sans lives by is this:
    “if there's a possible worst case scenario, it's always gonna be the worst case scenario.”

    Summary

    You walk into a skeleton one frozen winter day and surprise him by apologizing. You don't think anything of it - You're Canadian, after all! - but to him and his friends, it means the world to them.

    I wanted some more romance and a more realistic, super slow build up than a lot of the SansxReader fics I read on this site, so I decided to write something of my own :) It starts with some background SansxToriel, then it moves to a platonic friendship with the skeletons and their friends. I also wanted a much more assertive reader - There be no damsels here, whether overprotective Sans likes it or not.

    A lot of the content in this is based on real events in my life, just rearranged to fit the story I want to tell. Many names have been changed to protect the innocent.

    Summary

    “Would you like to…become a trainer Sans?”
    Yup, that's right. Sans woke up this morning and now he is a trainer. Weird, huh?
    It gets better, because the professor wants him to go to Mr. Pokemon's house. Simple right? But it doesn't stop there, oh, no. Now he's on a mission; becoming the champion of Johto. Not exactly what the lazy Skelepun dreamed of but...hey...why not?
    That's what you do when you live in the world of Pokemon. Yup, everything is totally normal.
    Yet Sans swears there is something weird going on. Why can't he shake the feeling that he's not meant to be here? How come some of these "Pokemon" are acting so...murderous? Where are all these random memories coming from? And what do all these nightmares mean?
    Oh well, might as well go along with it, yeah? After all, new buddies to meet, new places to see, and Pokemon all over the place! Maybe a lot more violent then he would like but hey, there are still fun times ahead! What could possibly go wrong?

    Summary

    It’s just a ribbon.

    Just a plain red ribbon, absolutely nothing special about it.

    At least, that’s what Sans tries to tell himself as Frisk stares up at him, their expectant look slowly morphing into confusion while he sits there frozen.

    (Or, the story of the Underground as it was and as it will become, spanning thirteen years, various timelines, multitudes of lives, and one very tired skeleton that just wants very desperately to go home.

    In which Frisk isn't the first human child Sans meets, nor the first he befriends, nor the first he kills—and being Sans in general is complicated as all fuck.)

    Summary

    The monsters were finally free. But, unfortunately, Frisk and their friends were separated by the police, who locked the monsters up and handed Frisk over to social services. The monsters had to achieve Full British Citizenship by proving they had lived in the UK for thousands of years, even though the only family of mages, Frisk's family, in the whole country who knew of their existence have been murdered or kidnapped. With their family gone, their sister missing and Toriel not even recognised as a person yet, Frisk's future was uncertain.

    Toriel only wanted all the best for Frisk. Sans begrudgingly felt bad for the kid and, maybe, might want to find their missing sister, Mist.

    Frisk just wanted their family back.

    (Formerly named Misttale: The Tale of Frisk and Mist.)
