1 Reverse Falls
In this alternate universe, the main characters' roles are reversed, with Dipper and Mabel being the antagonists and Gideon and Pacifica as the protagonists, creating a new dynamic in the town of Gravity Falls. The places people switch with fit but don't fit at the same time, because you know the canon characters so well. This AU is still cool though!
I like this one because of Will, he's so cute!
I just love reverse/opposite aus!
2 Monster Falls
In Monster Falls, the characters are transformed into mythical creatures, such as Dipper becoming a deer, Mabel a mermaid, and Grunkle Stan a gargoyle, changing the way they interact with the supernatural world around them. Ew god that's bizarre. One, he's twelve, and two, you're attracted to deer legs? Oh boy, this fandom needs help.
I think it's better than Reverse because everyone is still normal.
3 Blinded Pinetree
In this alternate universe, Dipper suffers a tragic accident that leaves him blind. As he navigates through the challenges of his new life, the Pines family and the residents of Gravity Falls come together to support him. In all honesty, I find this very interesting. I have not seen a lot of art or fan fictions out there though. I found myself looking into it as much as I can, trying to find all the information I can.
Dipper looks really cool in this AU.
4 Gravity Rises
Gravity Rises swaps the ages and roles of the main characters, with Dipper and Mabel as adults and Grunkle Stan and his twin brother Ford as children, exploring a different perspective on the mysteries of Gravity Falls. I just don't like how Dipper was the goofy one. Dipper's always been my favorite character and it feels weird seeing his personality on someone else. But, I like seeing pictures of him and Robbie getting along. So, yeah. -Author Note
This AU is my favorite! You guys should totally go on Wattpad and search up Gravity Rises! Praise to Brightnesswings!
5 Reunion Falls
In Reunion Falls, the Pines family reunite in Gravity Falls years after the events of the original show. The characters must now deal with both new mysteries and the emotional complexities of their relationships as they have grown older. Don't know much about it but from what I do know it is so adorable!
6 Transcendence AU
This alternate universe follows the characters of Gravity Falls after they are exposed to a magical event called the "Transcendence," which grants them supernatural powers and immortality, changing their lives and the world around them. Bill was about to succeed with his plan of destroying the world but was stopped by the pines family. Dipper and mabel did an incantation and nearly killed bill, but not enough to completely destroy him. As a last attempt to save himself, bill tried to take the life force of the nearest person... Dipper. But instead of letting bill take over, dip fought back thus reversing the process and instead accidentally took bill's demonic essence.
Again, I have NO IDEA what's going on in this AU. At least in the relativity Falls AU I got the basis of it. But for this one, I don't even know how Dipper ended up like that.
7 Rebel Falls
Rebel Falls reimagines the characters in a dystopian setting, where they form a resistance against an oppressive regime that has taken over Gravity Falls, fighting for their freedom and the town's future. I like this one
8 Anti-Gravity
In Anti-Gravity, the characters find themselves in a world where the laws of physics no longer apply, and they must adapt to this new reality while trying to uncover the cause of the strange phenomenon. This is cool because in this one, you see Dipper (Hot! ) and Mabel in Wendy and Soos's shoes for once. Or maybe it's just because in this AU Dipper's going out with Pacifica. Big deal... Yeah. It is. I'm a total shipper. -Author Note
9 Fight Falls
Fight Falls is a universe where the main characters are trained in combat and martial arts, using their skills to protect Gravity Falls from supernatural threats and uncover the town's hidden secrets. This one is my favorite.
Best out of all
10 Relativity Falls
Relativity Falls reimagines the roles of the main characters with Grunkle Stan and Ford as children and Dipper and Mabel as their adult guardians, exploring the mysteries and relationships of Gravity Falls from a new perspective.
The Contenders
11 1920s AU
Set in the roaring '20s, this alternate universe reimagines the characters of Gravity Falls in a time of jazz, flappers, and prohibition, bringing a new historical twist to the town's supernatural mysteries. Go ahead and imagine if the show took place in the 20's. It's cooler than it sounds.
It is the best place to be but be careful who you trust can be dangerous

17 Depravity Falls
Depravity Falls is a darker take on the Gravity Falls universe, where the characters face more sinister threats and must confront their own personal demons as they try to protect the town and its secrets. I have no clue what this AU is about. I just like the pictures.
