Summary
Mafiafell take I had made.
Constant war meant the development of new methods of destruction. Hopes of catching everyone else off guard with a weapon they couldn’t combat or find a way around just long enough to stay on top until the newest shiniest thing made its way to the market. Mechanical enhancements, biological modification, higher powered weapons. Its a constant struggle for king of the hill, a never ending toppling and growing market with worse and worse.

Summary
“Sans!” Papyrus’ voice broke Sans from his thoughts and he turned around to see Papyrus holding a tiny fluffy animal on his lap which they’d learned was a “kitten.”
Papyrus’s eyelights were heart-shaped and glowing and a wide smile stretched across his skull.
“Sans! It is adorable! This little creature immediately approached me and started rubbing its face against my rib cage. All while making the most peculiar rumbling sound. It likes me! I think it wants to come home with us!”

Hello!
This is a rewrite of a old fic I made(it still on this acc infact -w-), I don't know if I'm going to finish it in fact the text in this fic rn is like a month old sooo, uhh, I will try to but no promises lolOld description:
The Underground was a peaceful place, Until the king and Queen sons died. By humans, the underground went into anarchy, Until the Royal Scientist, Found the power within Lust. now a long, long time later a human fell into the underground.Notes:
So, uhh, I have dyslexic, and this is my first story, so sorry if the story come out slow. But hopefully I don't forget about this. And the main thing I should say this a full rewrite of underlust, because in my opinion at least the story not that good. So, I'm just going to try to rewrite it, to the best of my abilities, and this will be the shortest chapter, hopefully.(And I have not read other rewrites of underlust like Underlust NT, Underlust zirkkun, etc...)

Mettaton has a cop show and Frisk is unfortunate enough to be part of it by Slugfox

Summary
The monster-human city of Home, along with several other cities, has been part of a years-long experiment involving DT technology. The results of DT leaks (read: Dark Fountains) are well known, and the police are prepared to deal with the aftermath. However, after several leaks occur in the span of a few days, the police chief Alphys begins to wonder whether there's something darker going on. Could there be someone purposefully causing these leaks? And what effect will it have on the newest officer-in-training, Frisk?
An AU where the Royal Guard are swapped with the Royal Scientists. Also it exists simultaneously with Deltarune, and Darkworlds aren't really a thing. (The Darkners still exist though). Trying to be close to canon, but will do whatever my brain thinks is a good idea (like starlo bucket). Yeah, it's complicated. UTDR cop swap.

Summary
It's easy to think about those who are important, how they would interact with eachother and in new situations...
But what about those outside of that box? Who are more free to move, do, and be as they please? What about relationships unmentioned, unwritten, unexplored just because they simply are not important to who perceives it all?Perhaps what can be said, be seen, be experienced...Are still not that important. Not real. Just things that seem like fantasy.
But still...New things can be considered, if you simply take a look from a new angle.A collection of disconnected writings from the perspective of a mere background character, Doggo.

DISCONTINUED!! Gosh This Is Horror-ble (reincarnated as HorrorTale Sans) by Foxonfire
Fandoms: Undertale (Video Game)
30 Apr 2025
Tags
Summary
!!DISCONTINUED!!
A story where you, the reader, are reincarnated as horrortale sans, some things you still retain from your past life, like
You're not sure what this new life has in store for you but nothing could compare to how bad your past life was... right?
*WARNING* there WILL be blood and gore depicted, not exactly that detailed but be cautious if you get triggered by that.
This is cross posted on Wattpad in case you prefer reading on there!
It’s called “Gosh This is HORROR-ble” under @chipped-cup
Horrortale does NOT belong to me
Be prepared for bad grammar and bad spelling I am doing all of this on my phone so please don't expect to much.
I try to update on Friday every week, on occasionally Sundays too, so there will be weeks with two chapters up!

Summary
You managed to escape being trapped underground after running into the forest when your parents died in the war. You were up on the surface from birth up until you were the human equivalent of 18. On your 1800th birthday, you escaped your abusive foster home to join the rest of your kind below Mt. Ebott.
I update very irregularly, I try my best but don’t expect updates every week. I tend to evaporate off the face of the Earth sometimes. It’s either that or you get 3 chapters in one day. Have fun reading!
(I hate slow burns, but this won’t be quick. There will be children and unusual anatomy because skeletons) -
