    Summary

    A published series of minifics to help me practice writing and to get a few headcanons/accepted theories in type.
    Most of these are going to be really short and headcanons will be explained in the ending notes if you want more context as to wtf i'm talking about.

    Most of these are probably going to be Sans-centric since I have the most theories about him but most of them involve other canon characters so don't worry.

    Tags will be added as I continue.

    Summary

    the people around you are a bit more concerned about your wellbeing than you like.

     

    “i haven’t been avoiding you,” you say.

    you’ve only had more important things to do at the most inopportune times, unfortunately.

    “CUT THE CRAP,” gaster says. “LET US WORRY OVER YOU IN PEACE.”

    Summary

    One hundred fluffy moments in the lives of Papyrus and Mettaton. Some are silly, some are angsty (but end happily), some are just pure fluff all around, and all involve the skeleton and the superstar charting their course through the puzzle known as love.

    Summary

    How, then, does one define a ‘soul’? Is it developed over one’s lifetime or the moment they are born? Are some naturally evil, rotten from their very core, or is such a thing learned? Does it have something to do with genetics? A difference between blood and magic?

    How do people grasp the idea of what makes them themselves when such an idea is easily discarded?

    OR -- the AU in which a monster absorbs a human soul and the consequences that come from messing with the continuity of the multiverse.

    (ANOMALYTALE is a mix of previous ideas/AU's ive messed around with over the years, including my old & abandoned au, devastationtale. some chapters may be unsuited for certain people, so please make sure to read tags/warnings before you read! hope you enjoy!)

    Summary

    Plot Twist: The reason why Sans is so salty is because Undyne stopped taking out time for the skelebros after she became Captain, but bothered to take out time for both Alphys and Frisk.

    Summary

    Undyne rarely dreams. Ask anyone from her childhood, even back then, she always had two feet ironically firm in reality.

    Papyrus would tell her later, with a slight twinge of sadness, that it didn't really matter anyway. She'd just keep remembering, like it or not.

    Undyne finds herself back in the Underground, the crunch of snow underneath her boots.

    Summary

    A week has passed since the human’s defeat—the Underground and all of its inhabitants are still shaken from the attempted genocide, but life is at least starting to return to normal. Monsters are returning to their homes, Alphys is continuing her research on determination, and Asgore and Undyne are working to rebuild their devastated kingdom. However, not everything is going smoothly. Strange things have begun happening to Undyne, things she can't explain, and soon it becomes apparent that something is very, very wrong.

    Summary

    "...You really want to hear my story, kid? It's... not exactly the happiest, sorry to say."

    *No. ("...Good choice.")
    *Yes. ("...Fine. Remember I warned you, though.")

    "I know it's my story you're wanting, but... It might help shed some light if I take several steps back into the past. July tenth, eighteen thirty-eight; the birth of the king we all know now, who was then just a little ball of fur with the title of a prince... Before I go on, are you sure about this?"

    *YES, I WANNA HEAR! ("Jesus fuck, alright!")
    *NO, I DON'T WANNA HEAR! ("Then leave. Simple as that.")

    "Alright, fine. Exactly one-hundred and eighty-seven years ago, two races shared the Surface in peace: monsters and humans..."

    Summary

    Sans is struck with sudden headaches without warning and has no idea how to heal them or where they came from. In the span of a month, he's too weak to get help and too dazed to wonder about the half of himself that feels missing. And the way he seems to be changing right under his own nose.
