The Glitch (An Undertale OC Story)

by LizLizLuvsSans

Everyone knows the skeleton brothers Sans and Papyrus. However, in a far off and forgotten alternate universe called x-tale, a third skeleton is in the mix. This is the story of the monster Arial and the human Kayla, BUT both are the same person. I don't own Undertale, x-tale, underverse, or handplates, all of which are used in this story. They belong to there rightful owners.

Hi LizLizLuvsSans here. This is my first story that I'm writing about my Undertale OC so right off the bat, if you hate OCs please don't read. Also I can't promise frequent updates because this is more of a side project/idea that I just had in my head. I also do take story ideas but I can't guarantee that your idea will be used. Anyway I don't want to keep you long so, enjoy the story :)

You've all heard of the story of monsters and humans. How both races went to war, and how humans won and sent monsters underground. Then many years' later monsters were set free by a human named Frisk. That is the story everyone knows. This, however, is a different story. A story of one who is both human and monster.

That would be me. I have two names. As a human people call me Kayla. As a monster people call me Arial. I am a rather rare case. So rare in fact that there's only one of me in all the multiverse. Yes, I can travel the multiverse, but I used to have a universe of my own. That is where my story begins.

In my universe I lived with the skeleton brothers. The punmaster sans, and the cinnamon roll Papyrus. But this story starts far earlier than when Frisk fell. The skelebros and I used to be experiments, mere tools to a monster named W.D. Gaster. He used the skeleton brothers on other experiments while I was used on side projects. I remember when I first woke up.

~Flashback~

I open my eyes to find myself in a big glass tube filled with liquid. At first I was quite scared and banged on the glass. Until I notice I'm not alone. For some reason another skeleton is with me in the same tube. When the big skeleton walks in he look surprised to see two skeletons. Within another second I black out. When I woke up again I found myself in a tube of my own but I still see my previous partner, who is on my left. To my right is another skeleton but a little bigger. He is in a tube as well. We all stare at each other for a while until the biggest skeleton takes my partners out.

*Gasters POV (but still flashback)*

I was looking through my notes when I remembered I hadn't checked on the two subjects in the tube chamber for a while. I decided to do it right then. What I found however was…. Startling to say the least, but also interesting. I came in to find subject 2-P to be completely fine. However subject 1-S's tube had an extra. There were two skeletons in that tube….twins. I realized that the piece of bone used to make him must have split. I had to get the extra out of there before something bad happened. I used magic to put them to sleep and transferred them to another tube. I found that they were Female, unlike their twin. There split had also resulted in them having lower HP then most monsters would have, not something that would be uncommon with twins. I put the twins down in my notes and went off thinking of what I would do with the "extra tool". Later I came back to take 1-S and 2-P out. I'd decided to label the third as 3-A and use her on "other projects".
