HC: Dipper comes across a paranoid demon expert who has set up cameras all over his house, and to be a little shit he decides to haunt the guy by doing demon-y shit in front of the cameras. He doesn’t realise that he’s still physical from a deal when he does it, so he is visible in the footage making ghost noises, waving his arms around and chortling to himself, generally looking like the massive demon dork that he is. The footage winds up online, and of course everyone dismisses it as fake because, heck, no way Alcor the Dreambender would ever act like that, right? This doesn’t stop Dipper from becoming so embarrassed that he turns beet red despite not even having red blood anymore. Mabel and the triplets tease him for a week over it. Dipper fantasizes about destroying the internet for months.

Weird thought: Dipper decides to find out EXACTLY what happens when you microwave metal things. Years later, they finally find the blade of the knife he used… In the top of the totem pole. On the other hand, Dipper is pretty sure the handle just vaporized.

Gliese foster branch
I have this headcannon that Willow’s child collecting tendencies end up getting passed on to (some of) her children, and (some of) theirs, and so on and so on for generations until it ends up becoming an official branch of foster care, geared specifically towards orphaned (or otherwise in need of care) children due to cults and/or demons. These kids would most likely need some special therapy, may never fully recover, and it would probably be wonderful for them to live in an environment where their little quirks that are just a tad bit stranger than most aren’t looked down upon or mocked. Kids who absolutely cannot stand fire, or must avoid forks at all costs, or will have a full blown panic attack at the smell of bubblegum fit in just fine here.
What was originally one house in Gravity falls spreads to hundreds of houses all over the world. Councillors and foster parents who wish to work in the Gliese branch must undergo much more special training than normal, and be prepared to do their own research if a child comes in suffering from a demon or cult they’ve never heard of. Only the best wards are placed on these homes, and an extra security detail is always on call in case of vengeful cults or parents.
And of course, throughout the years, the “Gliese” name always stuck around for some reason, and by the time they became official the name was stuck. And if the occasional omniscient dream (dork) demon comes by to drop off a child, they’ve learned not to question it.
R!Pacifica Headcanon
All of Pacifica’s reincarnations find themselves, for a time, in possession of the axe dropped by the Lumberjack ghost. The time and method varies from incarnation to incarnation; Orion received it from Alcor as a wedding gift the day he married Mizar, and bore it throughout his life, while Helen found it in her attic, having apparently just transported itself there by unknown means, and lost it the next day, shortly before the cult she was a part of made the lethal mistake of calling up what they couldn’t put down.
Dipper’s not sure why, exactly, it happens; there’s no obvious spell or enchantment, any involved beings either don’t exist or are very good at hiding themselves. In the end, it just seems the will of the universe.
HC: Dipper gets summoned by someone a few thousand years into his life who is fascinated by the early history of the internet, and since Dip’s been around since it’s relatively early days, the summoner asks to be filled in on it all. Dipper spends hours explaining the lore of memes and the websites of old such as reddit and tumblr, and all the while the summoner listens with wide eyes and gasping in awe.
HC/Prompt
Sometime in the future, an aspiring author writes a book about Bill Cipher and his role in the Transcendence.
Only it is an epic fantasy about the deadly conflict between Bill Cipher and Alcor the Dreambender that spans ten thousand years and cumulates in an epic final battle between the two in the town of Gravity Falls, which inadvertently causes the Transcendence, and ends with Alcor devouring Bill Cipher and absorbing all his power as his own.
It includes such things as a dramatic, romantic sub-plot between Mizar (In this version, Alcor’s half-demon daughter) and the Woodsman (In this version a human soul enslaved and warped by Bill Cipher.) A blood soaked origin story for a character who is in no way based off the infamous demon hunter Wendy Corduroy. Etc. Etc.
It of course is nothing but pure fiction, and too be fair, the author doesn’t claim it to be anything but. However, in several places the story hits uncomfortably close to the truth. For example, one scene has a boy named Tyrone Spruce sacrifice himself to Alcor in order to save his twin sister, (thus giving Alcor the extra power needed to defeat Bill Cipher,) and whom the author admits is very loosely inspired by the story of a boy who was in Gravity Falls visiting his great uncle, and was killed during the Transcendence.
There is a sub-plot about an occultist who runs a tacky tourist trap by day, but a night secretly works to avenge his twin brother who was destroyed by the machinations of Bill Cipher. (The author once visited the Mystery Shack when he was six, and wrote the character in honor of the memory.)
There’s a sub-story of a rich heiress who summons Alcor in order to have him banish a ghost which haunts her family. Alcor agrees, but as price, the Heiress is forced to confront the past crimes of her family and walks away a better person for it.
And so on and so forth.
Dipper is partially uncomfortable about the story which hits very close to home for him, but that part is drowned out by the nerdy part which revels in the story and the demonic part when preens at being the center of the story.
Bonuses:
– If the Author actually read Twin Souls, was disappointed to discover it was a trashy romance, and vowed to do better.
So here’s an idea… a long time in the future some researcher or something finds some old pictures of Alcor, and is just kinda like ????? because in all of them he’s holding an odd sign, with old writing on it, and when they translated it, it’s stuff like “I fell asleep on the fan and broke it.” It’s dipnip shaming.

Fic Prompt: Henry and Mabel attend a preternatural rights protest. shit goes down.

HC: At some point, Dipper sets up an Instagram account, and uses it to post pictures of Eldritch abominations too horrific for even the internet to handle, resulting in several people being scarred for life and Dipper’s account being permenantly deleted.
Considering I am cursed with the height of 4’9 I can relate to all these headcanons about Mabel’s shortness. I feel like she would have a glittered or bedazzled step stool in the kitchen so she wouldn’t have to always get someone to help reach the top shelf. Or maybe she’d just climb, but that isn’t very fun when on your period. (or when pregnant, probably)
OH GOSH YES.
and yes she both climbs but also has her Designated Tol Person to come fetch things for her when she isn’t up to climbing
