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

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
At first, it felt like déjà vu.
Funny, really, that he couldn’t remember when exactly he started remembering. Things in Snowdin didn’t vary much, but it became unsettling when they stopped varying at all.

Summary
After doing everything the right way in the first timeline, Frisk was compelled to do the genocide route for what they felt were "good" reasons. In doing so, they have broken utterly and become something new. Something absolutely devoted to Sans, and not remotely sane. Now they are striving to fix everything and find their path forward. What the hell is Sans supposed to do now?
(This is not an erotica story - it's a drama / sort-of-romance that eventually gets really spicy)

But.. their sins still crawl on their back… they have to make it right and tell everyone what had led up to this happy ending… only for them to not be forgiven by one monster.”

Summary
Frisk makes a decision. Someone else is left to face the repercussions of actions that weren't his own. How can you be honest with those around you, when no one remembers what you went through?

Summary
This is if one of my characters met the characters from Bubblyship's stories "Sans House Guest", "Shadows of Remorse", and "Soul of Fire", so go read those to understand.
This takes place 13 years after the ending of "Shadows of Remorse", when Mirazu accidentally stumbles upon the underground and finds them all hidden down there (all kids are already born and are 2 years younger than they are in "Soul of Fire"). But after she shows them her secret when they get found by the SCP Foundation, she soon realizes that maybe her family was closer than she thought...
All it took was one fall down the rabbit hole.

Summary
“Sans?”
“Yeah, kid?”
“Could you paint my nails?”
Sans slid his glasses a little further down his nasal bone, turning slightly in the kitchen chair to face Frisk. Physics textbook still open on the table before him, he cocked his brow, speaking inquisitively.
“Paint your nails?”
Frisk finds some nail polish and would like their nails painted. Sans is happy to oblige.
(Rated General! No real angst, no nothing.)

Summary
The games of the gods can sometimes be very cruel, but that's what gods are for. When they want something, they can always get it, but what about the consequences? To hell with them!
Ink and Error are gods, as well as Death and Life. Dream and Nightmare are intelligent Guardians. They stand a step below them.
