I'm cool and awesome so ignore my continuity errors and read this before I decide to abandon it for the rewrite ideas!?! (Fic one is complete but not posted fully, fic two is WIP but honestly almost done, and I have several sidefics planned and ideas for a rewrite already)
Measure Once (Check Twice)
Have you ever thought that those Aware vs Unaware Singing battles were peak fiction and normal sans should also just spontaneously turn into Dust/Killer? Well this fic is for you!!
Desc under the cut because it's long and annoying
Undertale was famous across the Multiverse. The building block for every AU after, the one universe that Ink did not create, the fragile yet powerful people within - for the death of one outside the bounds of a RESET would be the death of every one of their counterparts, corrupting worlds and subsequently causing the downfall of the Multiverse.
The copies however…they were less notable. Those that grew as timelines to split off into AUs of their own right were known, yes, of Dusttale and Horrortale and Aftertale and the curiously named Something New, but rarely would a single copy stand out.
Except one. Infamously banned from ever being touched by Multiversal interference, that one rule that even the Bad Sanses held to, a freakishly unstable AU that had experienced so many timelines that the RESET was glitched, causing the Sans within to live through Dusttale and Something New. But when those timelines reached the same point that the originals had multiversal interference, the RESET button malfunctioned and sent them all back to the original Undertale timeline, only the equally glitched Sans beyond its influence.
But this story is not about the Multiverse at large, no; not a single SOUL dared to touch the absolute mess that was Undertale#297. Yet in the heart of that mess, its final timelines began to unfold; the consequences of tragic history not remembered, the results of what it had wrought upon its sole survivor.
Or; haha lol funny bone skeleman sans guy sometimes just a little fucked up and silluoy (generically inspired by good old 2020 gacha Bad Child/Aware vs. Unaware where Dust and occasionally Killer would just. Show up. Casual possession. Some mechanics inspired by Merging Timelines by Werecat1234)
(All chapters will probably just be first drafts fuck it we ball, description being written in a manic haze at 2:40am and I've just been saying "What's up gangalang, it's me, ya boy!" for the last hour. Everyone intentionally OOC as FUCK this is raw self indulgence and my description is getting too long I'll shut up now)
