    Summary

    You may know this song and dance by now, the stories where a creator gets dropped into the Undertale multiverse and makes some skeletal friends.

    More than a few stories exist where a creator is dropped into a 'skeletons stuck in a certain world' scenario.

    Fewer still are the tales of creators becoming skeletons themselves.

    I joined the Undertale fandom a long time ago, but when I started writing down some ideas I had, I never would have expected joining it to be meant in a literal sense, and I definitely would not have expected my sibling to join me on our adventure.
    Now rated T for certain topics inherent when talking about some sleletons' backstories

    Summary

    *What would you do if everything you thought you knew was a lie?*

    Just when Frisk returns to Sans, the blooming flower has to make a deal with the 'devil' to save her family from a horrible memory and sold her memories.

    But, as the story begins again and she slowly gathers all her memories back, Frisk had to wonder:

    Which story is true? The one she thought she knew or is there more?

    Summary

    This little skele, a Sans type, is used to taking on whatever title was expected of him. So when the entire multiverse tells him he is a 'Bad Sans' who can really blame him for joining others who fall under this title. That is as long as Nightmare finds him useful. His past titles have left him with a very limited set of skills, knowledge, and expectation. Yet he is willing to give up so much more just to stay.

    First chapter is NSFW, and then there aren't going to be much until maybe in the future. Plenty of triggers so please tread carefully, I am not used to posting for others to read.

    Summary

    Nebula, Victor, Dynasty, Mimi, and Neptune are as thick as thieves and then some. The group had been friends since childhood.

    When Dynasty invites them to watch her play an otome game she got at a thrift store, with the explanation of ‘the antagonists kind of look like us’, things get out of hand very very quickly.

    What do you do when your trapped in a video game? And why is there a new skeleton love interest around every corner?!?

    Summary

    After Aliza gives up her soul to free monsterkind, Sans is tasked with going above ground to get enough souls to break the barrier.

    Summary

    Sometimes life throws you a curveball. For you, your curveball was going to bed looking like a human, and waking up looking like a monster.

    A skeleton monster to be precise.

    With the barrier breaking, a large surge of magic descended on the town you live in, and transformed you overnight. Unsure what to do with you, and the others changed, you're ushered into a facility until a monster with similar magic can take you to teach you how to wield the now uncontrollable magic you've been given. After waiting in this place for four years, you'd given up hope that anyone would ever want to take you.

    What a surprise for you when you find out that someone does. A lot of someones.

    Summary

    Souls. They are the very culmination of our being. Every single living person, monster, alien and robot, has a soul. Now imagine if all those souls made up a person or, if I was to be more accurate, a monster. A monster that was never meant to exist. A mistake.

    Summary

    You woke up to a dizzying headache. Your arm and left leg hurt too. Something felt wet around your head. You tried lifting your right arm to touch your head. Your eyes blinked open and you held your hand in front of you. It was red with what you assumed was blood. You slowly cast your eyes around you and were met with gravel laid dirt. You blinked because you knew that couldn't be right. You had been on your trip, there was no way for you to have gotten dirty. Then it hit you, you were on a plane before this.

    Summary

    Plot device is convenient, and the Human always causes mischief. Thanks to said mischief, the skeletons are introduced to entirely new world, one that is both adorable and disturbing all at once.

    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!

    Master Name Key at the Bottom!

    Summary

    Nightmare isn’t used to asking for help, it’s not like he’s ever received it when he had asked; but his crew is hurting and dying, and when backed into a corner he’ll do whatever it takes.

    Sans and his mages haven’t really signed up for this crap, until they do.
