Summary
Exactly what it sounds like; Flufftober 2025 with UTMV, except there's a different ship (almost) every chapter. Every chapter is in a different universe--except when they aren't. I don't know what else to say. Expect OOC-ness and fluffiness.
Also, I apologize, half of these ships do include Nightmare. I have a favorite.
Now including a table of contents! And if you can't tell, this won't be finished by the end of October. We persist, however.

Summary
Humans are afraid of the unknown. The solution to this problem? Welllll uhh... it's obviously to shove the problem in area 51 one and then build a school the size of America's need for healthcare since copies of the problem JUST. WON'T. STOP. SPAWNING. So follow the story of the troublemakers of wing 4-B I guess..
or
I shoved a bunch of random characters in area 51 and built a massive school on top of it because why not at this point. And characters are very ooc.
(Not that much knowledge of the characters is needed)

Summary
You, dear reader, have been transported into your own AU — as Sans.
Just when you’d begun to settle into this new, bone-white life, one small mistake sends everything spiraling.A malfunctioning machine, a flash of blinding light, and suddenly you’re falling through worlds — each one a reflection of stories you once imagined, and others you never dared to write.
Gaster calls it an experiment. Papyrus calls it an accident.
But Sans — your Sans — knows it’s something deeper.Every jump takes you further from home, and closer to the truth behind the tether binding your souls.
Will you find your way back… or lose yourself to the story you created?Whatever happens — the worlds will never be the same now that you are part of them.

Summary
The entire point of this fic was that I wanted to throw Sans AUs into as many fandoms that I have not/rarely seen it in as possible.
[This is not a bunch of oneshots. I promise there's an overarching story line.]
Tags will be added as the story progresses.**
The multiverse has never been safe.The Undertale multiverse. Quite the phenomenon, yes? Yet, something has gone wrong. Error, the infamous destroyer, has gone missing. And it seems he started a chain reaction as more Sanses go missing.
Believe it or not, the Void is not nearly as empty as one would think. Yes, there are those who fall into exist within the Void. There are also those who keep it in working order. Janitors they are called. The Void doesn't like people in general. Especially not those of great power such as the Destroyer or the King of Nightmares. Normally, the Void would just wipe them. But this time, it can't. So what do the Janitors do? Dump the offenders in the nearest habitable multiverses while they try to figure out what the fork is going on.Friends must be separated for the sake of survival and the sake of salvation. Can they find their way home? Will there be home left to return to?

Summary
A household full of skeletons are competing over the attentions of one love.
This isn't that house though. Unbeknownst to the group secretively wrestling with their chaotically unpredictable love lives and universe-meddling machine, another house a few doors down has been gifted with its own skeleton posse clamoring for the attentions of their own little lady.
A little old lady by the name of Mabel.Is there a bitty or a monster you would like to have a bitty version to drop into the story? I might find a way.
Lots of plot to come, aiming to update monthly when I can, depending on work and life! -

Summary
"I'm sure you're wondering what's going on here."
"Not really."
"You are genuinely one of the most pedantic people I have ever met in my existence."
"Well, I don't know what that word means, so therefore I can't be it.".
.Ah, frick, just my luck. Reincarnation as a skeleton with godlike magic capabilities.
This should be fun.
________________________________________________
Two friends, split across the Multiverse.
Two friends, with opposite ROLEs of the Protector and Destroyer.
Both just want to find their friend, for them to be ok.
The Multiverse has bigger plans for them, however...
One friend fights valiantly for what is right.
The other falls into the darkness.
Or: two kids make themselves spawn in the UTMV as Ink and Error, and both are overpowered.
Generally random updates but I try to keep it consistent to once a week.

Summary
Dust set his books down on the coffee table, managing to avoid collapsing. Where were the others? He looked around. The supply run had been mostly successful, but it had done a number on him. Dream had thrashed his ass, then Blue and Ink had handed it back to him neatly. There was also the problem of that human he had brought back…
This is my first fiction, so ignore it if it’s very cringe. Thanks!

Summary
Disclaimers:
Several details in this fic are heavily inspired by 'Blue joins the bad sanses' comic, so go check that out
Canon innacuracies: Passive and Corrupted Nightmare are the same person, Ink is the creator and not the protector, Ink, Error, Nightmare, and Dream, are all gods, Blue, Killer, Horror, and Dust's specific au timelines were all destroyed, and i took liberties with how the void works. Also, no Cross sans will be mentioned, i don't know enough about underverse, and there will be some OC non-sans God/entity/things later on. The fic will be split into parts, each lasting nine chapters.
Schedule: Once a week, on Saturday, Sunday, or Monday, and i will post art or a reference sheet with every chapter. Trigger warnings will be specified in chapter notes. I've never written for undertale before, so please let me know what you guys think :3With that said, the actual plot: After an injured Error crashes into Nightmare and Co's home, a close bond starts to form between the two gods, both forced villains. In light of Ink's attempt to kill Error, Dream finally starts to lose it, and Blue gets dragged along.
Average chapter length is 500-2000
