Oneshots based off of my fanfic Ace in a hole! Featuring a platonic relationship between Sans and Alastor, as Alastor is canon aroace and Sans is often headcanoned to be aroace. Some of these may be continuations, some may be entire AUs.

They fucking reek. That's the first thing Sans notices about these animatronics. It doesn't take long until he notices other things about them, and after a lovely little meeting with the companies lawyer, Sans is blackmailed to keep working for the company. He thinks it'll be easy to collect some evidence and get the company to sink. It's... not that easy. With learning how to coexist with those who tried to kill him previously, every layer of the mystery he unravels only opens more and more questions. Sans is just trying to survive. --- Undertale x Fnaf crossover, updates the 1st of every month.

Due to tight housing conditions on the surface, Sans accepts a desperate, last minute offer to shack up inside of this old radio station in the mountains temporarily. It's a bit of an awkward fit, but it's a roof and Sans isn't going to couch surf with Paps anymore now that he and Grillby are official. He'd like to keep the image of his brothers innocence, thank you very much. And Sans honestly didn't realize how much of a steal he got. The building is perfectly reserved. There's this old radio room that Sans swears is full of vintage, classic 1900's shit. Of course it doesn't take long for the part time stand up comedian and part time scientist to throw on the old equipment and see if he can take a crack at it. What he doesn't expect is some jolly, charismatic dick to be on the other receiving end once it's up and running. --- Undertale X Hazbin Hotel, centered around Sans and Alastor.
