Summary
Red went dumpster diving for leftovers, but instead he found a friend. Good thing his brother is so open-minded and accepting, otherwise things could go hilariously wrong!

Summary
You watch them suggest names and argue with each other as you stand there dutifully like a newly-adopted dog. Rus sidles up close to you and looms over you like a hanging specter. His smile does not look friendly.
“How about..Snowy,” He suggests, his grin widening at the twitching grimace on your face.
How to survive a blizzard and nonconsensual teleportation to a dilapidated sci-fi basement.

Summary
Again…
They couldn’t believe it, years of progress wasted, a promise broken, how could they face everyone after what they had done?
But with a blurred memory and a familiar, yet somewhat strange, turn of events, maybe things are not what they expected.

Frisk wakes up in the underground... But it is not the one they are used to. Faced with familiar faces and determination to get through the underground peacefully, they face many challenges.
Or: Frisk wakes up in Underfell, things are hecking messed up compared to what they're used to, and they are smol. I love it and can't wait to see what happens next! Definitely an all time favorite.

Summary
“so, you’re uh…” the blue skeleton in front of Sans had an odd pinched expression.
“an advanced AI” Sans clarified and his social program hissed at him to relax his posture “nothin’ more an’ nothin’ less”
Sans’ analytics quickly gathered the expression of each skeleton monster in the room to come to the conclusion that something was off. He carefully noted the odd atmosphere as the chime of a directive made itself known.
FIND A WAY HOME
Something in him settled and the red circlet at his temple evened out to a mild yellow.
“you sure about that pal?” the first skeleton’s red twin said as he picked his golden tooth after a pause.
“my social programming’s pretty complex, it can be hard to tell i‘m just a machine” Sans tried not to let incredulity sneak into his voice—of course he was sure.
“THAT CAN’T BE RIGHT” a lighter blue skeleton said rather intensely and Sans’ analytics scrambled to see where he went wrong “YOU HAVE A SOUL. RAZZ CHECKED YOU EARLIER”
Sans blinked at the accusation.
Or
Sans is pretty convinced he’s a machine, everyone else is convinced he’s got issues.

Sans Tumbles Through the Multiverse Headfirst by PapilioVolens

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
