-Author's note: Shi was originally just a design concept till i fell back into the Undertale fandom, now i wanted to turn them into something more- Shi is half human, half monster, with their soul breaking from the magic they wield being stronger than their body can handle, and trying to flee from their home after they were found, after so many years of living in the security of their home with their parents, till their father, who was a monster with illusion magic was found out and killed, now Shi had fallen into the underground, this is where the story begins (this focuses on the main bosses in Undertale because i don't want to have to describe over and over again smaller boss fights)

Authors Note: I legit died when I found out no one else had this. So it's mine! Muahaha! Frisk falls and discovers the beautiful, colorful world of monsters, a stark contrast to life on the surface. But can she convince them of the horrors that await outside? Or will the monsters grow together to bring life back to the human race?

My own Undertale Au, it's a work in progress and if anyone wants to use it they just have to credit me. This Au will also be posted on my DeviantArt account WeebWebooOtaku101.

{THIS IS DISCONTINUED } This is sad. There is a trigger warning. There are mini swears so yah. This is my first story. IF YOU LIKE REASONABLE GRAMMAR AND UNDERTALE THIS IS FOR YOU! If you want to see the character designs I have a story for that. Please comment I would like to hear your feedback also BRING BOB ON A WORLD TOUR AND SHARE HIM WITH YOUR FRIENDS (if you have any, I don't)

Heyo! So, if you've been reading my art book, you'll notice I've been developing an AU for Undertale. I'll be posting in here to spare those reading/viewing my artbook. I'll be posting pictures, and have descriptions attached to them.

Abandoned on Mt. Ebott at the tender age of five, young Harry's unsurprisingly died, but Death's always had a weird relationship with his variant... Meanwhile, before Flowey's revival as souless talking flower, Sans makes a discovery under the mound of snow, Papyrus has always wanted to be a big brother anyways. *Edited Summary (29/09/2025)

Sans and Papyrus were just trying to have dinner. They didn't expect things to blow up (literally). Now they have a destroyed machine and a young babybone that they suspect as a Shifter. Where did they come from? And who's life privilege they need to remove? Because this babybone is clearly been abused or worse. Now then, where's that parenting books Sans been storing since Papyrus a babybones, he's definitely need a review if they want to keep the kid from getting killed. At least the kid's adorable...
