Summary
Ignored, underestimated, and lonely. All you ever wanted was to be apart of your family, but you feel as though that will never be the case.
This is inspired by DOUBT, an Undertale fic that was orphaned as of 04.28.21.
The reader is an adopted child of Sans, Papyrus, and several of the popular alternate skeletons (Underswap, Underfell, and Swapfell). They often ignore the reader in favor of their second adopted child. The reader has stopped caring and has decided to take her life into her own hands. The reader plans to follow her dreams, with or without her family's help....
...
But they want to help... -

Summary
This is my first fic, so please be gentle.
You live in a city in the 1920s, and it is overrun with mobsters. Because of this, you're extremely cautious and like to stay informed about what is happening around you, but you come across a man with quite the... unique mindset for a mobster. You don't trust him at first, but he'll win you over eventually.
He will make sure of it.This is short for now; I will be adding more later, as I'm currently sleep-deprived.

Summary
December Holiday is a human living in Snowdin after she fell into the Underground years ago. She has a band with her best friends Chara and Asriel, as well as her sister, Noelle. She lives a fairly normal life, except for the fact that she's one of only two humans living in a place filled with monsters. She's always felt distant from her community in more ways than one, and everything turns even more upside down when she finds some mysterious things hidden in her own doctor's laboratory.
This is a weird Human Dess Undertale AU that came to me in a vision, where she lives in the Underground and was adopted by the Holidays shortly after falling down. There's a lot of twists and turns in this one, as well as Chara Dreemurr content (my beloved), among many other things.

Summary
You're an engineer who works for Ebott's best research facility in one of the labs; your lifelong dream after finding a journal on Mount Ebott when you were a kid. When you aren't in the lab being smart, you're gathering materials at the abandoned doll factory for the machine you're trying to build.
But one night, you meet a skeleton at the factory. Naturally, you lie about why you're there and say you're there to hunt ghosts. You befriend him and try to find a way to gather the materials while keeping up with that lie. But those lies catch up to you when you start to meet all the other skeletons.
Edit: As of Chapter 29, all chapters have been edited and fixed slightly!

Summary
Sans has a mission, and Aliza is a part of it.
She will persevere through anything he puts her through.
She has to get out of this hell hole. She has to help Sans with his mission. It's a good thing these things align, but it sucks that they align in such a way-- Aliza doesn't want to hurt anybody.My work for AI-Less Whumptober! It's all one continuous storyline, this is NOT a one shot book (I'm bad at those lol)

Can however, was not only born soulless, but they never even gained their soul even after the first year of their life passed. As a result they ended up lacking basic Human emotions like: Happines, empathy or fear.
Can didn't know why they were like this but they didn't like it, especially not when it was the reason their parents gave them away to the orphanage. The Orphanage wasn't much better, so they decided that they would leave them all behind, even if it mean lteaving behind the one good friend they had there. Can did this to finally find the one thing that has been missing in their life:
a SOUL.And Can's search for a soul has led them to a certain mountain.
