Summary
In which a GF-fangirl wakes up to find herself in the body of a baby Bill Cipher before the events of canon happens. Welp, lets see how much she can fuck this up.
(Updates once every other week)
(Now canonically a shared universe with the Triplet AU, Dimension 46'/-A and One Way(to absolve his crime))
IMPORTANT NOTE: Ok, so I've decided to just put a warning right here about BlueBill from Dimension 46'/-A. He's not a good person, and is going to trigger a lot of people. Also putting up an angst warning for when things get super emotionally draining as a result of BlueBill and other terrible things making MizBill spiral into depression.
This is backstory, character exploration, slice of life and very much a cradle to the grave sort of thing. And... apparently the romance is finally coming up. Woop?
This is not meant to be taken seriously, it's just a stupid idea I'm writing for fun.Series

They go on many adventures, and love blossoms slowly between them.

Summary
UPDATE (30.09.2025): Chapters from 1-22 are gonna get updated soon due to me finally learning how to space things out correctly + to fix the formatting in the dialogues and such. NEW SCENES ARE GOING TO BE ADDED AS WELL. (5/22 complete)
In a chaotic twist of fate (or more like a weird trial from an ancient, cosmic axolotl), you find yourself married to Bill Cipher, the interdimensional demon and chaos incarnate. Two weeks into your new life together, you're just trying to survive the absurdity of being legally bound to a two-dimensional triangle with a massive ego and questionable decision-making skills. With Bill floating around making strange observations about the horrors of human biology and occasionally trying to "bond," things are... well, let's just say "normal" isn't in the cards. Will this be the most dysfunctional marriage in the multiverse? Probably. Will you survive? Maybe. Will it be hilarious? Absolutely.

The Dark Ages Of Bill by Behavioral_Unit091_B, selfless_solipsist
Fandoms: Gravity Falls, Till Weirdmageddon Do Us Part (Fanfiction)

Summary
In a land most cursed and confused, where the forests whispered legal threats and the rivers flowed with questionable soup, there reigned a kingdom most foul. 'Twas a time of plague, poor hygiene, and peasantry so dense it could be used to reinforce castle walls. A time of dragons, damp moats, and monarchs with more inbreeding than sense.
In this time—this era of mud and misery—there lived a princess.
She had never known love, nor wanted it. For what mortal fool could match her?
And lo, that answer descendeth from the heavens like a flaming middle finger from God.
A star fell.
Nay, not a star—a triangle.

That's right! Bill gets busted out of his Axolotl mandated therapy only to realize his arch-nemesis and favorite human is dead, gone and buried. He doesn't take kindly to that fact, and decides that chronological time is for losers who doesn't know how to make sweet deals.
Now if only he could get his stupid, spiteful, stuck-up, stubborn, snarky human to take him back! I mean really- What's his problem? Bill said he was sorry. Okay he didn't, but that's what he meant! Maybe. Sort of.

Summary
Powered by foolhardy ambition, Stanford Pines was on the precipice of fully realising his Grand Unified Theory of Weird when divine inspiration struck. Cajoled into building an interdimensional portal by his otherworldly muse, our plucky protagonist was loathe to call in his old college buddy, reluctant to invite the vultures of the scientific community to descend upon his venture. Creating a loophole, Stanford fashioned a body for his flighty inspiration, pinning down the transcendental insight of Bill Cipher, intending to partner on this exciting new project, in more ways than one.
A wise man would have told him this was a stupid idea.
But wise men never fall in love, so how are they to know?
A canon divergent sci-fi rom-com detailing the span of events between building a body for your dream boy to watching him end the world. Featuring hits such as: discarding a lie, rejecting the truth and the mortifying ordeal of being known.
