Sans Tumbles Through the Multiverse Headfirst by PapilioVolens
Fandoms: Undertale (Video Game)
22 Jun 2025

Summary
Sans has finally managed to fix the reset issue. It only required the deletion of a vital character. The barrier is broken, and time finally begins to move again. Recovery is slow, but Sans finds solace in his dreams. By the time he realizes his dreams of other universes are real, he has already grown attached to their residents. And then he's attacked at home and is thrust into the multiverse proper. He finds things very different from how he expected. His old friends don't recognize him, and some of them appear suspiciously older.
It doesn't take long before Sans starts to suspect that he may have a larger role in the multiverse than he predicted.
I wanted more Classic adventures through the multiverse, so here's my contribution. And cause I'm me, I can't help but try to make a saga out of it.
Features Classic being Classic, strange multiversal mechanics, and a sleep-deprived author who 100% knows what they are doing
Important note: NOT on hiatus, just slow and life being a bitch XD

Summary
Sans has been in a mental (and physical) funk, so his doctor told him to start keeping a daily journal.
All the emotional moments... every day.
..even the ones he doesn't wanna talk about.
........
But, maybe he won't talk about it after all.- Language:

Summary
This is the tenth one. The tenth reset.
Nine times, the child wearing pink and blue stripes has commit GENOCIDE. Massacred nearly the entire monster population, laughed gleefully like it was all just a harmless game - playthings just for them!
In a way, it is all just a game.
Because one moment, he's bathing in the bright yellow light of the Judgement Hall, clutching a horrible gash on his ribs and sternum -
And the next, he's in the middle of reading "Peek a Boo With Fluffy Bunny" to Papyrus as his bedtime story.

Summary
Stars did Coffee regret what he’d done.
He hadn’t meant to, he really hadn’t; but when he’d heard that little voice begging for help through the speakers, he’d just reacted. Now his house is overrun with variations of him and his brother and their obnoxious girlfriend and her family.
No matter what he did things just seemed to be getting worse.
He needed an Angel.
You have been recently released from an asylum after years of being kept locked up, for nothing more than telling the truth. With nowhere else to go, you end up moving in with your half-sister and her boyfriends; it may just be the best thing that ever happened to you.
Ok your family may be jerks, and so are your sister’s boyfriends, but by some dumb luck, you’ve found your bondmate again and stars are you glad you have.
Things may be hard, you may be struggling to get back on your feet, but at least you have each other.
Now if you could just figure out what everyone’s issue is, and just why your sister is intent on practically keeping you prisoner, maybe you could make friend with some of these other skeletons and finally start living your best life.
upping the ratings due to the events in chapter 9.

Summary
Gaster's not even really interested in CS-1 or project PERSEVERANCE, he's just working on it because the current Royal Scientist told him to, and the king told the Royal Scientist to look into the option in the first place, so, hey, there's really not many ways he can argue his way out of this one. He'll just wait for the experiment to fall flat on its face so he can get back to the projects he actually wants to work on.
(CS-1 wasn't supposed to have a mind, and Gaster was not supposed to care about him.)

Summary
There was no hope.
There was no way out of this place. Sans knew that from the depths of his soul- he couldn't escape on his own. But without any way to contact anyone and no knowledge of where he's trapped, all he could do was try to survive... or maybe just hope for death.
No more resets, after all.

Summary
Horrortale Sans is stuck in an Underground where the only source of magic is dust.
Empress Undyne died long ago, having been eaten alive by her ravenous subjects. No ruler had dared claim the throne since, for they too would be eaten.
Sans's magic now runs red with Determination and it's the only thing keeping him together. Constantly bombarded with painful memories of the past, Sans does his best to reinvent himself.
- This Horrortale AU will eventually cross over into the canon Undertale AU.

Summary
Sans hid so many things from everyone around him. He had gotten used to having the RESETs to undo it when he slipped up, but Frisk had stopped resetting, and that meant that if Sans happened to slip up, he had to face actual consequences.
Like, for example, accidentally admitting his jacket was from a family member while his little brother was in the room under the impression that they only family they had were each other.
TL;DR, Sans fucks up and Papyrus wants answers.

Summary
No one has ever seen this "Sans" person, supposedly Papyrus' brother. This, predictably, causes some concern for the sixteen year old skeletons. Where did they come from? Where are their parents? Is Sans even real?
OR: Since no one has ever seen Sans, people don't quite belive Papyrus when he says he has a brother. Issues arrise.

Summary
After a harrowing trip through Underfell, Frisk is nearly ready to go meet King Asgore. Their adoptive brother and good friend Sans would rather they go anywhere else—anywhere at all, as long as they don't get to that throne room. After all, in this world, it's kill or be killed.
That's just this world, though. How about the next one over?
