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
Despite Color’s best efforts to keep Killer’s rescue under wraps, word had leaked out, and a small crowd had gathered outside of his hospital room.
Most of the people there were paparazzi. Useless leeches, he had no kind thoughts for. Thankfully, the arrival of Dream and his posse had distracted a majority of them, as they now could ask the Guardian all about his nonexistent contributions to the years-long mission of depriving his brother of the most deadly of his henchmen. And he, always polite as he was, had yet to shut them down or kindly ask them to fuck off.
Among that sea of people, the only one who seemed to genuinely care about Killer’s well-being (other than Color) was Blue. Soon after his arrival, he’d left the rest of the Star Sanses to go sit next to him. He’d asked about his best friend’s condition. Asked how he himself was doing. And even inquired whether he could do anything to make both of them more comfortable.
They were sitting in silence now. He and Blue.
A pair of acquaintances with the one thing they had in common, being hidden behind a wall. That’s what they were.

Wait, he just..did he just stab his counterpart-
Oh. Oh, shoot, he'd just killed this world's Dream.
These characters are not mine!

Summary
Deep within the belly of the Omega Timeline rests the Underground.
Not to be mistaken with the Underground— the forced sanctuary settled beneath mountain top: The setting for a story told many a time. No. Deep within the churning, hollow soul of the Omega Timeline rests the True Underground.
And, nestled deep within the pit of this chasm, rests a fight club.
Palette knows it as his second home.
Or: Hidden deep within the Omega Timeline, there exists a fight club and black market. Years ago, a sick doctor created life from little more than abandoned magic. Gradient escapes. Palette waits. Dream is faced with echoes of his past. Ink claws for his identity. And, Nightmare steps into the light once more.

Summary
A somewhat loosely connected story of Frisk venturing through the Underground with a sudden guest invading their body every once in a while.
No coherent plot, just Frisk and Chara interactions at different times of their journey, in which the two grow closer and at times where one can not appreciate their own appearance, the other can take over to state how jealous they are of their body.
Mostly silly and fluffy nonsense interactions planned, some gentle explicit stuff, too.Other Monsters/Characters will be tagged as they appear/become more frequent.

Killer is very fond of Color.
But what about the other lackeys in the Chromatic Crew?
Surely not everyone is okay with adding another to the friend group, especially when that someone is a mass murderer with the literal nickname "Killer."
