    Summary

    The multiverse reboots every once in a while, but left just one monster whose memories remain.
    Error.
    He was left behind, and thus the destroyer of the worlds could only cradle his rust-stained memories, watching as everything familiar faded. He observed the ebb and flow of the multiverse, while he himself gradually extinguished, as if the flame of anger in his heart had lost the fuel to keep it burning.
    Will he ever burn again?

    Summary

    If there is one thing that hurts more than anything, it is knowing you are somewhere you are not meant to be. If there's one thing worse than that, it's not knowing where you are, or what it is that gives you an off feeling. You are forced to endure rather then understand. You are pushed to hide rather than look.

    Sans has always felt as though something was deeply wrong with the world of which he resided.

    Summary

    In one multiverse, there is chaos.

    A Creator unknowingly tips the balance, and a Destroyer writhes in pure pain.

    The multiverse is governed by Fate and observed by Destiny, Karma, Light, Dark, Death, and Life.

    But what no one realizes is—they are not the first.

    Fate once created another multiverse… then abandoned it. Destiny, however, did not. Destiny gave it freedom and continued to watch over it.

    When the Destroyer is cast into the Void and crashes into that forgotten multiverse, they take him in as their own.

    And there, two beings—a skeleton and a human sorcerer—fall in love with him.

    Summary

    A Sans no le habría importado mucho ser confundido con su contraparte alterno, no, de hecho, Sans lo tomaría usualmente con gracia. Si… Bueno, eso no es algo que pueda aplicar a esta misma extraña situación en la que se metió “accidentalmente”.

    Summary

    A semi-modern world, between the 1800s and 1900s, circuses are a great sensation.
    You have worked in one since you were born, always following the family path.
    Everything in your show life was going great, until that cage arrived.
    Now you're stuck between a rock and a hard place, integrity and perseverance fighting fiercely for a victory that… doesn't really matter, because in the end, will there be any change?

    When the warm light falls on you and the music of its soft embrace, you will take a leap of faith.
    You will break their chains and yours, when the truth comes out and your soul guides you towards your destiny, squeeze the knife in your hands and remember to always smile.
    The audience awaits impatiently… it's showtime!

    Summary

    “Inez! Inez! I got accepted! Isn’t this amazing!” You say to your brother, bouncing in place as excitement coursed through you. Your brother Inez is reading over the acceptance letter, you could tell they were proud despite the mask covering their entire face.
    “This is incredible MC! I’m proud of you!” They reach over patting your head in a brotherly fashion before grabbing you by the sleeve and pulling you to their chest giving you a noogie. You wriggle in their grasp, swatting at them while laughing trying to free yourself.

    Summary

    The Human has always been good at getting into trouble. Thanks to said trouble, the skeletons are introduced to an entirely new world, one that is both adorable and disturbing all at once. These new, tiny skeletons are a handful, and the multiverse is not prepared for what the Fells will go through to help out these little monsters.

    Bitties may be simliar to other verisons of Bitties but they are not all exactly the same.

    A continuation of Light Drizzles introducing the Bitty Universe, turning out to be so massive it needed it’s own separate story dedicated to it. It is recommended you read Light Drizzles before reading this, but of course you don’t have to. There are some context stuff and events from the first story that are referenced to here.

    Featuring lots of Bitty artwork in most of the chapters!

    Summary

    Outer manages to -despite his VERY “careful” behavior- end up somewhere far from his home in space. It isn’t until he meets two winged skeleton brothers, that he realizes he may be in a little deeper than he had originally thought.

    Note, this is my very first romance writing! Yay! Also my very first peice shipping AUs, yay! And my very first time shipping Sanses! Yay…? I have decided to write an Undertale fic of every genre, (eventually), and I had to get around to a Sans ship, so… how about a ship I don’t see that often? BirdTale and Outer! Well, I can’t really say much, because it’s not like I see many AU ships at all. It’s not really my thing. Honestly I only chose these two because they both fly… I’m not very good at this.

    Fair warning from future me. I have tried it, and have decided I do not like shipping AUs. So, I might still try, but don't expect much from this one. I hate knocking things until I try them, so I'm not giving up just yet, but have higher priorities.

    Summary

    In an existence where multiple versions of you exist, it's not really that surprising that reincarnation or transmigration exists as well.

    In a world where balance is everything, where neither the good nor the bad are as they seem, let us accompany a certain skeleton's journey through a life entirely not his own.

    What would the people of that existence think now that a person that they once knew is overwritten and replaced by someone who sees everything in childlike wonder?

    Read and find out.

    Summary

    You sit with your paws together, and whiskers tickling the crying glass windows. Everyday. Waiting long hours.

    For them.

    —————————————————-

    You’ve lived a thousand lives, some you remember some you don’t. Every time you blink you get a glimpse of who you were once upon a time.

    Summary

    I bring you the area where I will put everything that is short and mini-chapters.

    Different topics that I like but i don't have the time to create a long fic…
    I will try more different topics here and even i will try to make new ones.

    I will add a lot of names from other authors here since my mainly idea is to help other people find ideas and create their own stuff.

    This area is for one shots, I think people calls them like that?
    Unrelated stories that have only 1 chapter or 2 if i make a pov from Sans.

    And also i will add the first chapter of long stories here to make you feel the boom of a new story beginning.

    That way you'll never miss one of my new fics and you will learn from yourself if you like the story or not.

    I accept ideas and suggestion. (Inside my possibilities and own likes)

    Summary

    The skeletons are on an adventure through a fantasy realm, created by the multiverses biggest weebs.

    Two of the multiverses biggest weebs have a fanfiction they MUST share! Along with the input of other “guest” authors and the skeletons themselves.

    Join the skelebros as they face demonic swords, “sexy” nymphs, crazy chainsaw wielding/pole dancing mob bosses, Jerry with a Gollum complex, and a slew of other mishaps along the way.

    AKA; The Skeletons are on a Dungeons and Dragons inspired quest, with lots of insanity along the way. May the dice gods and authors not screw them over too badly...
