Years after the first summer, something calls a pair of hunters back to what is left of Gravity Falls. [at least 10 years after the finale of Gravity Falls; somewhere in season 4(?) of Supernatural, but also within an AU/broken timeline]

One apocalypse wasn't ideal, but it was manageable. When they find out there's a second one looming, that's when things started to go a little off the deep end. Rated for strong language, no pairings.

After discovering the death of their parents, Dipper and Mabel Pines are placed into foster care. They endure it until one day when two strange men begin investigating the house across the street. When Dipper recognizes some of their gear he knows they're involved with the supernatural and wants to find out more. What the twins discover is more than they could ever expect On Hiatus

After Weirdmageddon, tons of monsters popped up in Gravity Falls. The Pines twins thought they were the only ones doing this job, but they're not alone. Disclaimer: I do NOT own these characters, just the idea of the story! ***were back in business ;P***

When Dean and Sam hear of a case in a small town in Oregon, they jump on the chance for a seemingly quick exorcism, but this case is not what it seems. Meanwhile, Dipper is faced with a choice as Bill offers a deal. What will the Winchesters find in dinky little Gravity Falls? And what will Bill have to offer? T for the usual language and such.

What would Sam and Dean do if they found out about the gravity anomalies in Gravity Falls? What will our boys do when their usual gigs surround monsters and demons of our dimension. How will they face the creatures from the multiverse?

Dean and Sam needed some rest from the never ending jobs and long car trips. In between a hunt they pull in to the sleepy town of Gravity Falls where it might not be as sleepy as they thought. And when they run into a certain set of twins things only get weirder.

Dipper and Mabel have seen a lot of weird stuff in their time- gnomes, zombies, long-lost twin brothers- but when they're thrown in the middle of a demon case on their way back to California, they have to figure out how to cope with a whole new spectrum of strange. Rated T because of some gore and language.

All Hell breaks Lose AU! Post- The Inconveniencing AU! The Winchester boys find their horrific fates taken from them! Unfortunately, their's no time to celebrate...for they've been given to 2 little twins we all know and love...will anyone survive the battle for Gravity Falls?(continued in 'Tales of the falls')

Fleeing from the demon that killed his wife. John Pine takes his twin kids to Gravity Falls, to be protected by his mentor Ford...Needless to say he's not happy to learn he's vanished...(continued in 'tales of the falls')

A strange murder in San Francisco. An even stranger warning on the wall. And a demon that's out for blood.

... there must be a key

Summer ended months ago with Dipper and Mabel heading back to Piedmont. But although some can clearly divide their lives into periods of supernatural adventure and times of normalcy, others aren't so lucky. Those left behind have to find a way to stay sane and hey, sometimes staring at a blank wall and rethinking everything isn't going to do the trick. S3 Supernatural no NWHS.

The Pines twins may have spent summers chasing monsters and solving mysteries in and around Gravity Falls. Then one night, the teens come across something they discover they couldn't handle.

"Too bad you boys are just passing through," she said.

Sam and Dean Winchester are more than used to spending the night in the Impala, but the way too friendly locals of Gravity Falls insist they stay the night. With the motel full, the only option is the place the brothers are pretty sure is the center of their upcoming hunt: the Mystery Shack. Continuation of sapphireswimming's Never Mind All That.

The stage is set and the script rewritten, all that the world is waiting for now is for Lucifer to break the cage and start the Apocalypse anew. But Lucifer isn't going back to Sam Winchester and Team Free Will. The Devil's in the details and found two new vessels to make an alternate ending, and Hell isn't planning on letting Heaven or humanity win this encore. Curtain Call sequel

They were all doomed.

Sam and Dean come across three hapless hitchhikers stranded in the middle of nowhere, and decide to take pity on them. This will surely end well. Warnings: so far...swearing, and alcohol mention..I guess.

Bill Cipher wasn't sure where to begin with his plans to free Lucifer, until he found the perfect stage in Gravity Falls and the perfect puppet in one of the special children who lived there.

It's been 10 years ever since our summer at Gravity Falls. The monsters outside are more vicious and blood thirsty. When our Great Uncles left and fought with it, they vanished and the responsibilities were left to Mabel and I to hunt the things living in the dark.

When Mabel and Dipper wake up in an abandoned town with five adults or When Sam and Dean save the lives of twin siblings from the Jake *I own nothing. Everything either belongs to Eric Kripke or Alex Hirsch

... down in the forest, we'll sing a chorus, one that everybody knows—hands held higher, we'll be on fire, singing songs that nobody wrote ... (Or, the one where Sock Opera is an utter tragedy.)

A girl comes out of the portal along with Stanford, Stanley's brother. This girl isn't like the others. She thinks Bill Cipher is a good guy along with the other monsters in the journals except the gnomes. Dipper and Mabel meet this girl and they become great friends. That is until she meets Bill and everything goes wrong. MWAHAHAHAHAHAHAHAHAHAHAHAHA

School's in session, and everyone has their own ways of coping. (Or, the one where Wendy still works at the Mystery Shack, but isn't terribly interested in the Mysteries anymore.)
