Summary
Doomsday prep has always been necessary in my opinion. If not for your time, then for another's time. So I got married young, to a much older, much richer man, waited a few years for him to die (cancer, so sad), and collected that money like candy at a parade. Then I picked out a nice place for a bunker, and had that thing built in another few years. When Monsters busted out of the mountain nearby, turning some Humans into Monsters, I was only slightly surprised the government's decision was to fucking nuke them all. Now I'm closing the door, and I see people in the distance waving their arms, yelling. I should just close the door, I don't know them, but I don't think it's fair to leave them out to die.
Author's notes, kinda:
Gonna be just Horror, Fell, and Fell/Swap variants.
Characters like Sans, Toriel, Asgore, Frisk, and others are really only mentioned, except Horror Sans.
Papyrus variants are more like different people in this, than variants of the same person.
Also, I don't really like Swapfell Pap (Purple) so sorry, but he might only be there for drama, not for a relationship -

Summary
Your life was terrible. Terrible working conditions. Terrible fiancé. Terrible relationship with any and all people around you. The only good thing that happened to you was getting struck by lightening and waking up in a house full of skeletons.
Okay. Maybe not quite a good thing to happen now that you think about it.

The Misadventures of Sans and His Very Normal Skeleton Children by Olrethaz
Fandoms: Undertale (Video Game)
16 Dec 2025
Tags
Summary
Grillby looked down from his bar to a familiar skeletal face staring up at him.
Sans?
But no, for as disconcerting as the resemblance might be this was certainly not a cheeky comedian. If anything, the little one (where are the stripes?) was still, almost unnaturally so.
Huh.
He hadn’t remembered any other skeletons about besides the goofy pair, but there was no way that one of them (Sans it looked like) could have possibly hid the existence of a whole person; or perhaps he had, one he didn’t know he was hiding to begin with-
“ya know where Sans is?” an eerie voice rang and the room stilled, silence as Grillby felt a headache, the world began to spin and-
A cheek-splitting grin “he’s my dad”
Sure, but does he know that?
All at once Grillby was wiping down his counters closing up his bar without knowing how he got there. He paused, then shrugged and figured that he should probably keep some sweets on hand for future reference.
Or
Sans acquires more children than he knows what to do with. Papyrus is ecstatic, the rest of the underground decidedly isn’t. The children(?) are absolutely no trouble at all, if you can believe it.

Summary
So I've seen someone else do this and asked myself, why not? I have loads of ideas/situations for fanfics yet have no time to write them or I end up just procrastinating for two years after posting the first chapter (if you're looking at my other fanfic no you aren't). So here goes nothing I guess.
Some will be longer than others, some I might expand on and make multiple chapters, but I don't think I'll make them into full fanfics. Some will have more oc's or more lore/backstory and some won't have any. Some will be about specific skeletons, others will be about all of them. There will be different tropes, jobs and personalities for Reader, and I might make them into a bit of a self-insert sometimes.
Again, if anyone likes any of these, please feel free to use them! But do tell me, mostly to read the end result ;)

Bewitched, Bothered, and Bewildered by CrimsonAndCloverOverAndOver

Summary
Cherry Sweet is a rather unconventional performer at a club like 'The Velvet Crop' with her thick thighs and plush stomach, but she does well enough for herself. The patrons enjoy a bit of variety, but what will she do when she attracts the attention of a monster--and a mob boss monster at that?
Featuring a 1920's vibe with music from the 20's-60's, a meet-not-so-cute developing into a partnership, and a spitfire, plus-sized FMC. I hope you all enjoy!

Summary
There are infinite opportunities in this world. Infinite opportunities for dreams. Infinite opportunities for hopes. Infinite opportunities for regrets... for loss.
There are some memories you would rather just forget...
The old royal scientist knew that better than anyone.
BRIGHT, BRIGHTER, YET BRIGHTER. SO YOU STILL SHINE ON, EVEN AFTER EVERYTHING YOU ENDURED. EVEN THROUGH THE COLDEST NIGHT.
But a story doesn't have to end the same way.
EXCELLENT. TRULY, EXCELLENT. LET US BEGIN THE CREATION OF OUR NEW FUTURE.
Sometimes... a game can have a secret ending.
(A Deltarune novelization that takes some unexpected turns from canon. Based on some theories, and a little bit of imagination, even the unknown can make itself known.)
(Custom Art and beta'd by Primordial_Rebel_Jester. Story by FoundUser.)
