An Unofficial AU Blog for the Gravity Falls Fandom

[NOTE: this blog is no longer active] Ever made up your own AU? Ever had headcanons for someone else's? Ever read that ONE fanfic that completely blew your mind? Welcome to the unofficial Gravity Falls AU blog where ranting about AUs is considered normal! Please read list of trigger warnings so you know what's out there. Feel free to submit artwork, fanfiction, headcanons, or even your own AU! Fair warning: I turn off asks and/or submissions when the inbox gets too full. Disclaimer: nearly all the content of this blog is product of the incredibly creative collective imaginations of the Gravity Falls fandom. I own none of it!

is there a master post somewhere that explains some of this stuff to a person (me) new to the fandom? haha I know I'm a little late to the party lol

Unfortunately our masterlist got a bit out of control, so it’s been discontinued and is incredibly out-of-date. The general premise of this blog is that it’s dedicated to Gravity Falls AUs! Try searching through the tags to find something. Sorry if this isn’t very helpful lol

where did the AU list go?

Hey! It got too long to be consistently updated with relevant AUs. If you’re looking for a particular one, they’re all tagged!

[alternatefalls]

Hey, have you heard of Fight Falls (not to be confused with Fright Falls)? As far as I can tell it's pretty popular, but I don't see it on the AU list. I'm not sure what exactly its about.

I've seen a few posts here and there? Where everyone looks badass and post-apocalyptic

monster falls au except gargoylse stan has feet ... elephant feet

What about that AU where bill is a human and the pines twins are little kids and Bill has to take care of them with the thought that traumatized them by almost destroying the world. I saw a short three panel comic on instagram and it had no context, I’m DYING to know what it is

Welcome to Gravity Falls

It’s a cross over of Welcome to Night Vale and GF. Essentially the characters of WTNV and GF are either all really good friends, or the characters are flopped. Like Cecil is best friends/flopped with Mable, Carlos and Dipper/Stanford are best friends/flopped (Dipper and Ford are interchangeable for Carlos, or any other scientist in WTNV. Mable can also be interchangeable for Tameka Flynn, with Wendy.

Hi, I'm thinking of starting a new AU. My OC, Natalie, is a normal kid from the real world who gets transported to the Gravity Falls universe through a naturally occurring portal. Bill is introduced very early in the fanfic due to this btw. I want to ask you two things: 1: Do you think my fanfic would get popular? 2: What should I name the AU? I was thinking Reality Falls but not sure.

Sounds super fun! Reality Falls rolls off the tongue nicely

Hey dude

Hey man, I ust wanted to know if it’d be cool if you could check out my AU. Well… ok not really me, more of a collab (cause I’m not all that good of a writer) but yeah the idea was mine. Here’s a link. I’m also trying to get people to check it out so this’d be an awesome thing if you could check it out. :D

A crossover AU with a darker shade of magic, where grunkle Ford is an antari. He can cross between worlds with his blood but one of his eyes are pure black. Bill is technically another Antari with a thirst for the magic that is runs in the Blood of the Pines family.

I don’t have an au name yet.

AU WHERE EVERYONE IS HAPPY AND NO BAD THINGS HAPPEN. NO BILL OR TRAUMATIZING EVENTS. JUST EVERYONE BEING HAPPY BECAUSE SEEING THESE LIKEABLE CHARACTERS SUFFER IT HURTSSSS.

Not that I know of? Sound super cute though, maybe someone else has an idea

[alternatefalls]

Hey, i was just wondering how you felt about people getting the dipper tattoo as an actual tattoo?

Admiration, particularly if they get it where it belongs: right in the MIDDLE OF THEIR FOREHEAD
