Mafia: The ancient skeleton word for family. That's what Sans was taught as a boy, there is nothing more important than one's family. But the person who taught him that was killed by his own son. Sans and Papyrus became trapped in an endless loop of death, money, and power. Then you come along. He knows things have to change or he'll lose you and Papyrus. Don Gaster must go down. This, I think, will be an attempt at a slow burn. I'll be expanding the Backstory from the original Feralmafia Short Story.

You would think that with how shit your luck is, you would've been dead day one since falling into the Underground filled with scary monsters and a few spooky skeletons. However, much to your surprise, that did not happen (yet). You know how you ended up here, but you don't know... HOW. You're actually in the GAME Undertale now. And to make matters worse, there are some people who KNOW. You're surviving the best you can, but things are only going to get weirder from here on out. Gaster apparently needs your help? You're using the DJ to go to different AU's? You are gay now?- Okay, maybe that last one is just a joke, but still! You can only hope that your instincts are enough to keep you alive in these trenches. On God, they tryin' to drown you in this hoe! {Available on Patreon, Quotev, and Ao3 under GabrielXander}

[THIS IS A SEQUEL TO MY OTHER FANFIC "WHEN TWO SOULS MEET!" If you haven't read it, I would highly suggest it--the story won't make much sense otherwise.] Sans has finally found someone he can trust--Frisk's sister, the eighth fallen human. After months of step-siding and awkward interactions, the two are finally a couple. Things are slowly falling into place--there are no more resets, and Chara and Flowey have been a lot more quiet in the last few months. But things can't stay this way... can they? Note: The story was put on hiatus early on, and updates are now very sporadic. Despite that, it's still a labor of love!

{COMPLETED} Sans' life isn't easy, and living in an Underground society filled with torture, rape, and murder doesn't make it any better. Every single day is a struggle, and Sans tries so hard to fit in with other monsters and live up to his brother's standards, but sometimes it's just too much. Will Sans be able to pull through, or will the darkening thoughts that are engulfing his mind and Soul take control, and swallow him up into a void too deep and dark to ever imagine?

While hiking with your family at Mt.Ebott, you end up falling down a hole in another world where you encounter monsters who want to kill you. Will you be able to change their hearts and bring back hope? Or will you be killed trying?

Over thousands of years the Underground's hopes of becoming free had slowly disappeared and have gone to alternative motives: Money, sex and power. A human soul these days has become almost priceless with very notorious gang members and it just so happens their luck has just rolled in. Not only a human has strolled into town, but she's been spotted by a well known mafia leader that goes by the name of Sans... and he just can't let a doll like her go.

Heya! This book will be a bit of a slow burn, which means that all the ~romance stuff~ won't happen until a little later in the story. ~~~ Twenty year old (Y/N) has sworn her undying loyalty to none other than Nightmare, one of the most feared villains in the multiverse. She's been working with him for years, since she was seventeen, but she's never encountered the infamous Star Sanses. She wishes that she could meet them, she hopes that she'll be able to fight them some day and end their existence. Her ultimate goal is to impress her boss and to prove herself to everyone who told her that she wasn't good enough. Will her wish change when she encounters the Star Sanses? Completed 12/24/2021 ~~~ Pronouns used in this story are she/her Disclaimer: None of the art used belongs to me!
