The Gravity Falls Fanfiction Wiki

  • Tags: Takes all sorts of Gravity Falls fanfics, except for Pinecest.

  • The man creates some great on-model (and off-model) comics and illustrations very true to the show that are just brimming with creativity, humor, and heart. You'll laugh, you'll cry, and you'll wow at some of the things he does with the Tumblr and DeviantArt formats. If you loved any episode, character, or concept, in particular, chances are that he's made something in response to it that won't fail to entertain you further.

  • Tags: Stories tend to be about Dipper, Mabel, and Stan, most of them set in an imaginary second summer in Gravity Falls. There's some Wendip, but not extreme, and the tales range from funny to angsty. My favorites: "A Father and Daughter Talk," with a 19-year-old Wendy and her dad sharing beers as she confesses her feelings for a 16-year-old Dipper. There are also "The Big Con," which brings the GF crowd into the real world, where they enter a Masquerade at a convention, hoping to win first place, "Trans Pacifica," which has a hilarious ending, and "A Taste of Ashes," which is surprisingly moving at times and reads like one of the darker episodes. Update: as of Dec 2016, there's one called "Christmas at the Shack," which is remarkably sweet and emotional. It's different from Super Grover Away's "Christmas with a Corduroy," but just about as good, especially if you like a kind of innocent Wendip.

Mayclore
  • Recommended by: Kandikorn 22
  • Tags: She mostly writes stories centered around Mabel and Dipper's brother-sister relationship, and she is fantastic with her descriptions of how the characters feel and keeping them in character at all times. Honestly, if you're looking for someone who can write a truly heartfelt fanfic, look no further than Mayclore.

anxresi
  • Tags: He mostly writes stories focusing around Pacifica's character development following Northwest Mansion Mystery, often taking inspiration from markmak's comics, one of his stories was even liked by markmak himself. He is really good at making readers feel for the characters.

TheBigZ1
  • Recommended by: Sean Devine
  • Tags: He's written quite a few Gravity Falls fanfictions, but my favorite one is "What Do Angels Look Like," which focuses on a young girl named Avy who Dipper finds and takes in after finding out her father abused her. It's one of the most emotional and heartwarming fics I've read, and I think it deserves more attention. When you're done with that, another fic I'd recommend is "Dipper and Mabel Jr," though it hasn't been completed yet. He's also written a few Pinecest stories, but I'm willing to forgive him for that.

SuperGroverAway
  • Recommended by: Chiropteru
  • Tags: Has written over 70 Gravity Falls stories, mostly one-shots, but also the multi-chapter "Little Shack of Horrors", a Little Shop of Horrors parody. Many of the stories are humorous, but the author also expands into horror, hurt/comfort, family, and angst, among others. Does an excellent job writing Dipper and Mabel's sibling relationship. Has also started a "future AU" series of one-shots, with the twins as adults.

ddp456
  • Recommended by: N8han 11
  • Tags: Has written many fics that shed light on Dipper and Wendy's relationship. The fics are very well written, and keep everyone still in character, all while still being interesting stories in their own right.

Transcendence AU
  • Recommended by: arsenicCrazy
  • Tags: A collection of Alternate Universe Fics taking place after a finale in which the Pines family prevents an apocalypse of sorts. The supernatural becomes commonplace all over the world, and Dipper is now a demon. A more detailed summary can be found here.
  • Comments: This AU is heavy on both angst and fluff. To quote the tags of one of the posts: "One half (of the fandom) is crying in the corner, the other half is in the fetal position overwhelmed with fluffy feels, there is no in between". You have been warned - bring some tissues.

Exotos135
  • Recommended by: Stellar Cannon
  • Tags: He writes a ton of heartwarming/random one-shots that revolve around the Gravity Falls gang. These are usually very well written, interesting and original.

DaintyDuck_99
  • Recommended by: American Handstand
  • Tags: This author has written a handful of delightfully quirky Gravity Falls fics, some of which focus on character speculation, and others that explore rarer pairings. Laced throughout all of them is an interesting use of metaphors and creative narrative. It's a bit sticky in some places, especially their first story (a Recess crossover), but the overall characterizations are great. One that especially stands out to this troper is Never Eat Soggy Waffles, a fluffy and wonderfully peculiar narrative about Stan and the twins driving around in a harebrained scheme that ultimately has them crossing paths with the still evolving character of Pacifica after Northwest Mansion Noir.

Omega Ultra
  • Recommended by: Stellar Cannon
  • Tags: He has written several stories for Gravity Falls that mainly focus around Dipper and Mabel. His fics are really well-written and actually get you to read them again, just so you can find the little details he's hidden inside.

    Shipping Fics 
Stories focused on the romantic relationships between the cast.

Pacifica's Revenge by Mon-Ra
  • Recommended by: CMR Rosa
  • Status: Complete
  • Synopsis: After being humiliated in Irrational Treasure. Pacifica plots to destroy Dipper by stealing his heart and grinding it to dust!
  • Pairing: Pacifica and Dipper
  • Comments: One of the best Gravity Falls fan fictions I have ever read.

Pines' Quest by mon-ra
  • Recommended by: CMR Rosa
  • Status: Complete
  • Synopsis: After the events of Pacifica's Revenge. Dipper prepares to make good on his word to become a perfect boyfriend for her. But will his sister Mabel or the new girl Rachel thwart his goal?
  • Pairing: Pacifica and Dipper

The Amazing World of Dipper Pines
  • Recommended by: Fourth Wall Breaker
  • Status: Dormant
  • Synopsis: After 2 years, 2 summers, Dipper and Mabel Pines have returned to Gravity Falls. When Dipper meets a new girl, could she be the love of his life, or just another pretty face? Created by the same person who created the Gravity Falls fanfiction wiki, this is her first Gravity Falls fanfic.
  • Pairing(s): Dipper and OC, Mabel and OC
  • Tags: Both Dipper and Mabel are paired with OCs. Het.

Dipifica Shorts by Viceroy Elf.
  • Recommended: by Hackstory, Red-Dead-Redeemer
  • Status: Complete
  • Synopsis: A series of shorts detailing the relationship between Dipper and Pacifica three years after the events of the show. The shorts are all part of the same larger story, and are (mostly) in chronological order.
  • Pairing: Pacifica and Dipper
  • Comments: Despite its uninspired title and a description (on ff.net) that says absolutely nothing about the story, it's well worth a look for any fans of the pairing. The individual stories are short and sweet with plenty of fluff, and all the characters feel very real to their cannon counterparts: it really feels like they're all the people they should be three years later. My only real complaint about it is the absence of certain characters whom I'm rather fond of: Wendy has yet to make any appearance whatsoever, and Soos and Stan are both almost entirely absent, themselves. Despite that, it's still far and away the best Dipper/Pacifica story that I've ever read, and I highly recommend it, even to non-fans of the pairing.

Incalescence by llyrical
  • Recommended by: foxkindle
  • Status: Complete
  • Synopsis: Dipper just wanted to have a normal college life- well, as normal as one could have it while continuing to research the mysteries of Gravity Falls. He did NOT intend to have to deal with losing all of his work just as he needed it the most.
    He also did not intend to have a demon be his only chance of getting it back.
  • Pairing(s): Dipper/human!Bill Cipher, background Mabel/Pacifica
  • Tags: Aged-Up Characters, Explicit Content, Magic Use, Dark Fic
  • Comments: All of the characters in this fic have been aged up to college, and the twins have been to Gravity Falls every summer until graduation when Dipper decided to move there. The events of "Not What He Seems" are incorporated into it. This fic has a very nice balance between plot and shipping. Very good characterization for Bill - even though this is a shipping fic, Bill is definitely not the fluffy, cuddly type, and is still very much a dangerous, sadistic and selfish dream demon - but apparently, even demons have feelings, and Bill can be nice when he wants to. Also, Mabel is a protective sister and poor Dipper is just a mess of anxiety and feelings. Warnings include: Moderately-Graphic Violence, Possessiveness, Memory Loss, Sexual Content, Nightmares, some really Dirty Talk, Scarification

Project Lumberdork by SuperGroverAway
  • Recommended by: TheDogSage
  • Status: Complete
  • Synopsis: Several years in the future, Wendy is invited to join the twins on a grand cross-country trip to investigate reports of paranormal activity across the US. But little does she or Dipper realize is that while they hunt and do battle with all kinds of monsters and oddities, Mabel is secretly working on her boldest plan ever...a plan to make the ultimate match.
  • Pairing: Dipper/Wendy
  • Tags: Slow Build, Future-Pines, Matchmaker Mabel, Supernatural Road Trip
  • Comments: Stated by the author to be a sort of "prequel" to his "Pines Will Be Pines" collection, this is a cute, humorous story about stressed college student Dipper, a Wendy who's still getting over a bad breakup, and Mabel planning to stealthily get them together over the course of a cross-country supernatural investigation trip for Great-Uncle Ford in a rust-bucket of an RV named The Lady Mabelton (by Mabel of course). On the way, they deal with vampiric cows, skunk-apes, subterranean worm-moles, and all manner of supernatural oddities.

Pacifica's Last Wish by lennoxmacduffles
  • Recommended by Loekman 3
  • Status: Complete
  • Synopsis: Set two weeks after Not What He Seems. Dipper felt great disappointment when the Author locked himself in the basement. He decided to go monster hunting and find the answers himself. Pacifica is puzzled for her recent behaviour after the Northwest party and seeks answers in the Shack.
  • Pairing: Dipper/Pacifica
  • Comments: This is perhaps one of my personal best Dipcifica fics I have ever read. The characterizations of the whole cast are brilliant including Preston, the romance is slow but so realistic and believable that I genuinely see the romance and chemistry between these two characters.

    General Fics 
Stories focused on the family and the friendly relationships of the cast. Plot-focused stories or light day-in-the-life stories. Pretty much anything that isn't focused on romance.

The Amazingly Astounding Bill Cipher Ask of AMAZEMENT by TopHatRose
  • Recommended by Maddy Raddy
  • Status: Dormant
  • Synopsis: Ask Bill Cipher your deep, meaningful questions, such as "Where do all the left socks go?" and "Is illoominatee confermed?11!" First come first serve, limit two questions per person.
  • Notes: This fic is surprisingly well written for a thirteen-year-old. Bill is perfectly in character, and I actually laughed out loud at some of the answers. All in all a pretty awesome fic.

Armor by Mayclore
  • Recommended by: The Icy Sneasel
  • Status: Complete
  • Synopsis: Mabel Pines' signature, heat-trapping fashion statement has a sensitive origin. When that nerve gets struck in an argument with Dipper, she ends up reminding herself of the things that are truly important to her.
  • Comments: A skillfully written and engaging one-shot that manages to include dark, yet subtle psychological elements while still maintaining the lighthearted narrative of Gravity Falls. Mabel is written very well. A very heartfelt story.

Some Day by last to dance
  • Recommended by ladyofthelibrary, Red-Dead-Redeemer
  • Status: Complete
  • Synopsis: Some day Stan will have to tell the twins the truth and change their world forever. A one-shot look into what could be Stan's motivation through the first few episodes.
  • Comments: Though it seems to come out of left field, the theory presented (that the twins' parents died 2 years before the show and the twins unconsciously used their innate magical gifts as Pines to keep them "alive" because they couldn't imagine life without them) makes a surprising amount of sense and makes Stan a surprisingly sympathetic character. In fact, I wouldn't mind if something like this was canon.

Dipper's Birthday Rumble by ddp456
  • Recommended by: Ryan Stoppable
  • Status: Complete
  • Synopsis: On his 13th Birthday, Dipper Pines receives a gift that he had always hoped for. However, an old enemy uses this to gain an advantage, and shortly, Dipper is launched into an unexpected adventure.
  • Comments: Fantasy/Parody. A very well-written tale of a game jumping adventure that would make Wreck-It Ralph proud. Features parodies of several well-known video game series.

The Rule of Cool by ryfkah
  • Recommended by Opftw 1
  • Status: Complete
  • Synopsis: Mabel hosts a sleepover party.
  • Comments: An adorable story featuring Mabel, Greta, Candy, and Wendy being awesome. Very clever and funny.

The Return to Gravity Falls by EZB
  • Recommended by: Sean Devine
  • Status: Ongoing
  • Synopsis: Once, a brother and sister went to a sleepy town in the backwoods of Oregon, and their views of the world were changed forever. Now, three years later, they must return to answer the call of that mysterious town. Old friends, new dangers, and dark mysteries await Dipper and Mabel Pines as they Return to Gravity Falls.

An Outsider's Look at the Pines Twins by iguessso12
  • Recommended by Neelh
  • Status: Complete, occasionally updated.
  • Synopsis: The Pines twins have been steeped in mayhem, mysteries, and magic every summer since they were 12 years old. Coming back home to Piedmont, going to high school, acting normal? All those things make them stick out like a sore thumb. When you ask outsiders about the Pines twins, you get a mix of strange stories and casual observations.
  • Comments: This is one of the first Gravity Falls fics I read, and I keep coming back to it. It's a series of oneshots with plenty of original characters interacting with Dipper and Mabel. The twins also have quite realistic reactions to their experiences in Gravity Falls, especially Dipper.

Christmas With A Corduroy by Super Grover Away
  • Recommended by Redandready 45
  • Status: Complete
  • Synopsis: For the first time in as long as she can remember, Wendy doesn't have to spend the end of December out in the woods doing the usual annual survival training with her family. The twins have invited her down to Piedmont so their friend can finally have the first genuine Christmas of her life. However, it seems that not everyone is happy to have a tomboy over for the holidays
  • Comments: It's fascinating to read a story without much supernatural interaction, yet still be full of the series charm. It's largely a story about Wendy finding her attitudes are less tolerable to a suburban mother, producing a conflict that fills you with laughter, tears and joy.

Code 12 by MayDayGirl-Save-Our-Ships
  • Recommended by Mondegreen
  • Status: Complete
  • Synopsis: Pacifica never used to fight with her parents. So when she finally sticks up for herself and runs out of the mansion, she heads to the only place she can think of, hoping that maybe this time, a door won't be slammed in her face.

Pines Will Be Pines by SuperGroverAway
  • Recommended by DVB
  • Status: Ongoing
  • Synopsis: Join the full-grown Mystery Twins and the rest of their family as they try to handle the endless paranormal absurdities and other ridiculousness that life continues to ceaselessly and inexplicably throw their way in this collection of one-shots from their near-future. Even as time goes on, there's still nothing that brings down the Pines clan.
  • Comments: This is a wonderful ongoing saga into the potential adult lives of the Pine twins. Starring Mabel Pines with her twins, Gladys and Finn along with Dipper married to Wendy. A mix of humor, good moments and the occasional action are mixed very well here with plenty of callbacks.

The Life and Times of Shermaine Pines by Sarielle
  • Recommended by: This Is Ridiculous, Dr Fabulous.
  • Status: Complete
  • Synopsis: "Before she is even old enough to understand she is loaded with her family’s lot: her mother’s a compulsive liar, her father never emotes and has taken to gambling, one brother is “a perfect genius” who “didn’t deserve any of this” and the other is, in her young eyes, some kind of Pines family ghost, a Bloody Mary character, you whisper Stanley Pines three times in the mirror at midnight, and he comes through, breaks the mirror, makes your father shout and your mother cry." Snapshots of the life of the youngest Pines sibling, born 16 years after her brothers, she is left to grow up in the wake of a family torn apart. Chronicling how a unimpressive skinny Jewish kid, from Glass Shard Beach, New Jersey got to be a successful Journalist, Activist, Mother, Grandmother, Matriarch, and the effect her brothers' falling out had on the whole Pines family.
  • Comments: I think someone recommended this but this is just in case nobody did.
  • The author has several other fics set in this universe, fleshing out the characters of Grandma Shermy and the extended Pines family.

A Gravity Falls Poem/song thing about Soos As he wanders the wastes because why not?
  • Recommended by Deadly Vampire Kisses
  • Status: Complete
  • Synopsis: You know how Soos said there were folk songs written about him? This is an example of one where he helps a desperate band of survivors get back on their feet. Warning, contains some gore.
  • Comments: Has a good rhythm and is well told. Not sure if this should be here or under dark because of some of the subject matter, but it seems a bit hopeful in the end so I put it here.

Attack of the Pacifica clones by {https://www.fanfiction.net/u/6046326/Mitchell-Movie-Productions]]''
  • Recommended by Bearquarter 2008
  • Status: Complete
  • Synopsis: Thanks to a cloning spell, Gravity Falls is overrun by an army of Pacifica clones, and Pacifica ends up finding herself as a tyranical ruler of Gravity falls. And it's up to Mabel and Waddles to save the town from Mabel's worst nightmare, a Million of Pacifica Northwest Clones. But can Mabel be able to stop Pacifica before her plot for World Domination unfolds?
  • Comments: This story is looking great so far in terms of the writing quality and the plot. If you love cloning stories, and if you love Pacifica Northwest, then read this fic, it's worth your time.

The Average Life of Tad Strange by Tad Strange
  • Recommended by: This Is Ridiculous
  • Status: Dormant
  • Synopsis: "Hello, I'm Tad Strange from Gravity Falls, Oregon. The other day a thought hit me, "Why don't I keep a journal?" I nodded to myself and then another bright idea struck me, "Why don't I keep a public journal!" That sounds like fun, I would love to hear from people outside of my home town. If you have any questions about me or the town, don't be afraid and ask away!"

Fisherman's Knot by scribefindegil
  • Recommended by: This Is Ridiculous
  • Status: Ongoing
  • Synopsis: Happy endings are messy, and the Arctic winter is more difficult than either Stan or Ford want to admit.

Axolotl by thesnadger

  • Synopsis: Somewhere deep in the woods of Gravity Falls is a half-buried statue. That statue is holding its arm out.

With Friends Like These, Who Needs Anomlies? by Healy
  • Recommended by: This Is Ridiculous
  • Status: Complete
  • Synopsis: In which Fiddleford Mc Gucket is not a very good research assistant, and Stanford Pines is not a very good friend. (A collection of short stories written for the 31_days community.)

Flat Dreams by PengyChan
  • Recommended by: Loekman 3
  • Status: Complete
  • Synopsis: Bill came into existence in a tightly regulated world, and it chafed him raw. But he never thought there may be other dimensions out there, until he found the memoirs of someone long gone...
  • Comments: One of my personal favorite Bill-centric fan fiction that expands his backstory on how he become a bored citizen of his own dimension into one of the greatest dimension conquerors to have ever appeared. One of the best parts here is Bill's brother whom despite being dead early on, remains a critical driving force in Ciphers motivation that somehow humanizes Bill as in spite of everything, cares about his brother.

Teenage Angst by AnimationNut
  • Recommended by: Loekman 3
  • Status: Complete
  • Synopsis: At some point in their adolescence, teenagers will experience a rebellious streak. At sixteen, Dipper and Mabel are no exception. Four times one of them got into a fight with one of their great-uncles, and four times their love for each other only grew stronger in the aftermath.
  • Comments: A fluffy and family-centric story that revolves around the teenage twins having a fight with their Grunkles with believable scenarios and consistent characterization. The arguments felt natural and I never felt a sense of Conflict Ball that occurred in this fic although the whole spanking thing is a bit too childish for my taste.

Flailing Spirits by Gabu
  • Recommended by: Acey Enn
  • Status: Complete
  • Synopsis: A little over a year since a car crash claims her life, Wendy Corduroy is summoned back as a ghost with a plea to help a certain first responder come to grips with what he had experienced, and to tell him that it wasn't his fault. The only problem? He has to be the one to initiate contact, and he is terrified of the prospect.
  • Comments: Beautifully written, and a very interesting concept—and it earns major bonus points for what, by all rights, should be a cliched twist ending feeling completely natural and incredibly satisfying. The characterization is spot-on, and the OCs fit in seamlessly. A long read at over ninety thousand words, but more than worth it. (Do mind the content warnings, though—they are there for a reason.)
    • The author also wrote a spinoff fic, If It's The Last Thing I Do, that is equally excellent, though Flailing Spirits should definitely be read first, in this troper's opinion.

A Midsummer Nightmare by CeslaToil
  • Recommended by RubyVisiblyShaken
  • Status: Complete
  • Pairings: Ford/McGucket, Stan/OCnote 
  • Comments: An absolutely gorgeous Fusion Fic between GF and A Midsummer Night's Dream. Feels exactly like the show, everyone is right on the nose- it's Midsummer with GF's off-kilter, snarky take on the supernatural. And though there is romance, it is also very much a gen fic. My review doesn't do it justice. Go on, read it already!

We Had a Deal by freakanimegal
  • Recommended by: Notriddle
  • Status: In Progress
  • Synopsis: Bill's deal with Dipper wasn't off at the end of Sock Opera; Pine Tree is now officially Bill's emissary and adopted child, complete with a growing ability to use Bill's (intoxicating) powers on his own.
  • Comments: No OC's. No shipping. Just pure drama of the gut-wrenching type.

Anyway, I've Been There by Caleb Nova
  • Recommended by: Red-Dead-Redeemer
  • Status: Complete
  • Pairing: Pacifica Northwest/Dipper Pines
  • Synopsis: It's the same place they left, but Dipper and Mabel aren't the same people who left it. A story of the uneven after, new friends, new family, and the promise of another summer. (Gradual Dipcifica, Mystery Twins bonding, family ties, and the Power of Friendship™ — anthyding can hadplen!)

To Gravity Falls From Piedmont by AnimationNut
  • Recommended by FanficFan920
  • Status: Complete
  • Synopsis: It's a long way until next summer. Until then, Dipper and Mabel share their daily antics and life problems with their lifelong friends and attentive great-uncles through an endless string of e-mails. Distance makes the heart grow fonder after all, and there's no place Dipper and Mabel love more than Gravity Falls.
  • Notes: This fic. contains a series of humorous Instant Messaging between the Pines family and the rest of the Gravity Falls gang. Everyone is in character, the jokes are spot on, and it really feels like a continuation of the series. Plus, the fact that everyone is still in contact with each other despite their distances from one another is heartwarming to think about.

In The Shadow of Death by A_Zap
  • Recommended by This Is Ridiculous

  • Synopsis: It all started with the grim. Now it seems like every time he turns around, Ford finds yet another death omen hanging around his brother. Seriously, what exactly is going on with his brother that death constantly seems to follow his footsteps? A 5+1 fic of the death omens that adopted Stan and he adopted back

Samsara (What's Old Is New Again) by Seiberwing
  • Recommended by Rubber_Lotus, Red-Dead-Redeemer

Quest for the Northwest Part 1 and Part 2 by ''Mystery Seeker's team
  • Recommended by: rufusluciusivan
  • Status: Complete.
  • Notes: This is a fanmade animatic. You can find the series' trope page here.
  • Synopsis: The gnomes are revolting against Jeff because he's a terrible leader, and give him an ultimatum: Either he finds them a new queen by sundown or they will depose him. At the same time, during the parade honoring the election of Mayor Cutebiker, Dipper and Mabel help Pacifica escape her parents' watch and have fun. Takes place after the events of The Stanchurian Candidate and before those of The Last Mabelcorn.
  • Comments: The first "episode" of a fanmade series of full-length animatic episodes called Gravity Falls Deep Woods. While the amateur aspect of the project shows in some of the voice recordsnote , the art is rather good and the story captures the spirit of the show very well. Special mention goes to the writing and the humour, which are well-done and very faithful.

How Old Are Babies Again by madwriter223
  • Recommended by: This Is Ridiculous

  • Synopsis: When Mabel and Stanley went off into the forest for something or other, Stanford didn't think any of it. Stanley was a grown man, he's able to handle himself. Right? Except... Stanley was definitely older when he left, Ford is sure of it.

Safe as Houses by Beastrage

Turning A New Leaf by by TheEarthbendingRavenclaw
  • Recommended by: Tropemaster 849
  • Status: Complete
  • Pairings: (Slow) Dipcifica
  • Synopsis: When Pacifica's finally had enough of her parents, she runs away with Dipper, Stan, and Ford on the Stan-o-War to hunt for the paranormal. But has she made the right choice?
  • This is, hands down, the best Gravity Falls fan fiction I have ever read. Everyone is in character and it makes for a very moving story as Pacifica joins Dipper, Stan, and Ford to hunt the supernatural. It is rated T as Pacifica's abuse from her parents is amped up from the show, due to the fact Preston used to put out his cigars on her if she acted up and the fact that they tried to force her into a marriage with a man she just met just to get their wealth back, but it's still a great read.

    Crossover Fics 
Fanfiction that combines elements, characters, etc. from two or more different franchises.

Garden Falls by starfleetrambo
  • Recommended by HalfBreedChaos
  • Crossover with: Over the Garden Wall
  • Status: The main story is complete, but the epilogue is not. (and he's making a few sides showing the other character's perspectives)
  • Synopsis: Dipper finds himself in the lost in the Unknown when he meets Wirt and together they try to figure out how he got there and how to help him get home.
  • Comments: This one was retweeted by Hirsch himself! The tone of Over the Garden Wall is carried over very nicely and mixes well with Dipper's genre savviness and a few other twists I won't spoil here.

Falling Over the Wall by skimmingthesurface and SylviaW1991
  • Recommended by kilala2tail
  • Crossover with: Over the Garden Wall
  • Status: Completed
  • Synopsis: After leaving Endicott's labyrinthine manor, Wirt, Greg, and Beatrice stumble upon more mysteries in the woods of The Unknown between the eccentric tea baron and the Mc Laughlin Bros. ferry. Specifically, the Mystery Twins. Dipper thought he'd been through every inch of the Gravity Falls woods, but he and Mabel had found someplace that was decidedly new and different. “If this part of the woods isn't in the journal, how are we supposed to find the way back?”
  • Comments: The first of the Mystery Best Friends series, it sets up the base for an entertaining crossover of these two worlds, with Mabel and Greg working to get their brothers together in later fics.

Shadow Over Gravity Falls by Kingxana0
  • Recommended by Underworldlurker
  • Crossover with: Multiple Disney shows/Marvel Comics
  • Status: Ongoing
  • Synopsis: Its been five years since Dipper and Mabel left Gravity Falls, and since then much has changed. Now that they have returned and brought a secret and responsibility big enough to change the entire world. But they aren't alone with this burden, as an old friend makes it clear she wants in. After all they are friends, right?
  • Comments: The blurb on the front doesn't really do much to draw you in, but once you actually start reading it this fic is quite the surprise. Expect to see faces from all kinds old Disney Shows. Also, the fic mixes the Marvel Universe into things. Seems to be doing interesting things, worth a read.

Things That Go Bump by appending_fic
  • Recommended by kilala2tail
  • Crossover with: ParaNorman
  • Status: Complete
  • Synopsis: Norman Babcock is touring the most haunted places in America, and his last stop this summer is Gravity Falls, a place with so many weird things going on, there have to be some spirits with major issues that need his help. Very soon, however, he finds that Gravity Falls is a place in a category all its own and that he might need a little help to keep from getting in over his head.
  • Comments: The start of Fire and Wonder, this is a tale of Norman and Dipper, magic and witches, with plenty of crossover interest to be had throughout the fics. A lot of focus is placed on Dipper, his fear of Bill, the insecurities of where he fits with his more "magical" friends, and his learning more about the not-so-invisible world around him along with how to help care for it.

A Conspiracy of Minerals by CompletelyDifferent
  • Recommended by Dude Wheres My Password
  • Crossover with: Steven Universe
  • Status: Dormant
  • Synopsis: A series of one-shots involving everything from the Crystal Gems touring the Mystery Shack to Bill paying Steven a visit in his dreams.
  • Comments: Perfect characterization for both shows. My favorite is Chapter 3. The one-shots are generally not connected, but there are hints of an ongoing plot in the ones involving Bill.

  • Synopsis: "The eventual heat death of the universe must be stalled. Imagine if your species finally developed enough to reach beyond your solar system only to find the rest of the inhabited planets have succumb to the inevitability of entropy."
    "And that's worth tricking hordes of kids into doing your dirty work?" Dipper sneered, his head not moving from the pillow as he spoke, he felt too heavy to move under the crushing information. But the creature held no sympathy for the boy. It held nothing for him. That was even less than the amused scorn Bill showed his family.
    "Your sister is a valuable asset to the Universal expansion process."
    At least Bill knows he's a jerk.
  • Comments: Kyubey comes around to Gravity Falls and makes a contract with Mabel. Set at the start of Season 2 and ties the new elements to the canon episodes al a For Want of a Nail. Another interesting element is how other supernatural entities regard Kyubey. (i.e. Bill, the Time Police, the Love God, etc.)
    • One of the other elements of the story is that the majority of the characters in Gravity Falls, bar Ford and some of the supernatural entities, are unaware of the Awful Truth of forming a contract with Kyubey, specifically Kyubey rips out the souls of those magical girls and places them in Soul Gems and their inevitable fate of becoming Witches. While the story ties in with the canon episode and slowly unravels the secrets of a Magica. Dramatic Irony ensues for readers who are familiar with Kyubey and the Magical Girls from Madoka's world.

Loud Gravity by Thunderstrike16
  • Recommended by EnigmusPrime, patriciovalencia117
  • Crossover with: The Loud House
  • Status: Ongoing
  • Synopsis: Living with 13 siblings, 11 sisters and 2 brothers in total is everyday normal for the Loud House but when they get sent to visit their Great Uncle Stan for the Summer in Gravity Falls, Oregon, some crazy stuff will happen. How will the Loud Siblings' deal and make it through the weirdness of Gravity Falls?
  • Comments: An AU where Dipper and Mabel are two of the Loud siblings (birth names Lucas and Leia respectively). Has two spin-offs: Gravity Loud, which is a prequel, and Loud Gravity Shorts, which applies the premise to the various between season shorts (Dipper's Guide to the Unexplained, Mabel's Scrapbook, etc.).
    • Okay, this sounds good on paper and has a lot of potential (and I do like the clever Star Wars Shout-Out). Unfortunately, what I've read so far is riddled with typos and spelling errors, not to mention how Mabel/Leia is occasionally called "Lyra". Otherwise, it's decent enough.

In The New Days by hapful

  • Synopsis: Almost all of the man- all of Ford was out of the portal, only his other hand still pulled back into the blinding light. Stan stepped forward, stumbled, ready for… ready for something, for anything, for finally finally god damned finally their happy ending when he realized Ford’s hand was connected to another hand, grasping it tightly as it too came out of the portal. Stan’s step faltered, mind racing against itself as another figure came out and into the light, one helped almost gently by Ford down safely from the damaged machinery. This figure wasn’t a man by any means, rather a slim, shorter shadow of - of a girl? A girl wrapped in similar dirty old clothes. She had a hood and face wrap as well, though hers had small bursts of color Ford’s lacked and her big, blue eyes were uncovered and taking in the room with an eager shine.
  • Comments: Author describes this as "AU where Ford ended up taking care of a certain dimensional space princess named Star Butterfly while he was in the portal"

A Rose Without Petals by CrypticMoonFang
  • Recommended by: ichigoare
  • Status: Dormant
  • Synopsis: For three years, Mabel has been in a horribly abusive relationship. She suffers countless injuries and severe trauma at the hands of her abusive boyfriend, Josh, while doing all that she can to pretend that nothing is wrong. However, when the abuse only grows worse and Dipper appears to be catching on to Mabel's lies, Mabel finds herself trapped. Sure, she wishes for the abuse to end, but does she want to risk others getting hurt? Will she be able to let herself get the help she needs?
  • Comments: While this is an incredibly well-written story that is sure to get an emotional response out of any reader (Cryptic is not lying when she claims she's trying to write the most angsty and emotional story on fanfiction; surely it's at least one of them), and it does an incredibly job portraying domestic abuse in a realistic light, from the abuse itself to Mabel's damaged emotional state and desire to cover up the truth of her situation at all costs, be warned- this story certainly earned its T rating, and anyone triggered by domestic abuse should avoid this story. That being said, the beautiful writing and the sheer amount of emotion put into it is remarkable. It's not an easy read, but it handles abuse realistically and manages to put our heroes into a dark predicament. For anyone who enjoys dark fics where the darkness doesn't come from supernatural elements, but rather from real-world situations, this is a must-read.

The Gremloblin's Mirror by Omega Ultra
  • Recommended by: Stellar Cannon
  • Status: Complete
  • Synopsis: After Pacifica goes too far and hurts Mabel, the twins decide that it is time to have their revenge on her. They decide to go after an ancient artifact that will help them fulfill their vendetta. Yet, their revenge may cause more problems than it will fix; and it may harm, more than it heals.
  • Comments: This story gets pretty bleak at points and yet, has some heartwarming moments sewn into the plot. Despite the author's original intention for it to be an experimental one-shot, it has turned out to be one of the best stories he has ever written.

The Town That Time Forgot by missakat
  • Recommended by: Jopalopa
  • Status: Complete
  • Synopsis: The town abandoned and left to fall to ruin, subject of many a horror story. Wendy returns to Gravity Falls, in order to pay respects to those long since passed.
  • Comments: This is, in my opinion, the best Gravity Falls fanfiction to date. Horror/Angst, and it works both extremely well while staying in the realm of plausibility (well, as plausible as a paranormal show can get).

Forget-Me-Not by ddp456
  • Recommended by DVB
  • Status: Complete
  • Synopsis: "Wendy mysteriously disappears, and a broken and distraught Dipper seems to be the only one who cares. The world believes she ran off with Robbie, and shortly, forgets about the missing redhead. Further searching leads Dipper on the path of a supposedly haunted house where teenagers are always welcomed, but are never allowed to leave..." Completed!
  • Comments: A Horror/Suspense story written by the same author who gave us Dipper's Birthday Rumble. A surprisingly dark and sinister tale that could almost seem a bit Lovecraftian at some moments. Characterization is good if not a bit off a few moments and also portrays the psychological impact these encounters could potentially have.

The Clairvoyant's Curse by jadefirefly3D

When things go south, the twins are forced to confront their biggest post-Weirdmageddon fears and regrets as they fight to make it out alive. But their need to keep the other safe may be what gets them killed. Some h/c, sibling bonding and suspense."
  • Comments: Suspenseful, creepy and angst-filled. The author mixes Mabel's guilt over triggering Weirdmageddon (which is still a secret) with an inventive original story. Characterization and atmosphere (with plenty of terrifying ghost imagery) are top-notch.

AntiGravity Falls by MagicMoneyPants
  • Recommended by: folkner
  • Status: Dormant
  • Synopsis: Based off the age-reversed AntiGravity AU. Where Wendy and Soos are twelve, and the twins are fifteen. Find out what kind of rollicking adventures these rapscallions get into!
  • Comments: A fanfic that uses its simple premise to remix already beloved content into delightful, new contortions; re-purposing the framework of familiar episodes to craft something new, interesting, and entertaining with them as their base. The first chapter's a little rough, but subsequent installments just keep getting better and better. I'd recommend trying chapters 3, 6, and 7 at least, as they showcase this AU and story's unique strengths at their best. The writing style is also worthy of praise. It's very straightforward and quick to the point, but it's detailed where it counts so all the jokes, action scenes, and character beats stick the landing in very easy-to-follow and visualize sequences.

Forever Autumn: The Destiny of Dipper Pines by E350
  • Recommended by: KTKomedy2813
  • Status: Complete
  • Synopsis: Summer has ended, and Dipper and Mabel have returned home. Dipper, split from Mabel, now faces a suffocatingly ordinary life as an outcast in an average middle school...but he soon finds that Bill Cipher isn't finished with him yet. Rated for future violence. Post Society of the Blind Eye.
  • Comments: A nice mix of continuation from "Society of the Blind Eye", which I guess can also count as an AU (and part-Dark Fiction) because of certain parts that've been revealed now (Not What He Seems, anyone?) and a good idea for a potential conclusion to the series. When Dipper and Mabel return home after summer, everything's duller and worse for Dipper, though Mabel seems perfectly happy to be back. That is until Bill comes back into the picture and tells Dipper that the world will end and everything he's loved and cared for will be lost forever unless he returns to Gravity Falls. What happens is a fun, exciting reunion of friends and family fighting the demonic dream triangle and his cult one last time. Highly recommended and deserving of its own page here.

And a new face shows up at the Shack while another old enemy resumes his plotting. Another mystery has emerged and this time the Mystery Twins find themselves as part of it. AU after Northwest Manor, with consideration for Not What He Seems.

  • Synopsis: A Gravity Falls fancomic by Deviant artist Jack-a-lyn. Grunkle Stan is running out of money to run the Mystery Shack, so Mabel decides to help by making a movie about a crack ship, resulting in a deal with a certain triangle...
  • Despite initially seeming like a set-up for a dime-a-dozen bill-dip work, it actually has a very good plot so far, as well as excellent art, as well as staying very true to the characters. So, if you're looking for a story featuring Human!Bill that's actually well-written, you've found it.

He has a mullet, he's living out of his car and he doesn't know he's her Grunkle. But he's not planning to let this weird, sparkly little girl end up alone on the streets.

Conspiratheory by LCypherEd

  • Synopsis: Dipper returns from Gravity Falls with three journals, twenty postcards advertising the Mystery Shack, one sulking ex-dream demon and the lingering belief that life post-near-apocalypse is likely to bore him to tears. He’s wrong, of course.
  • Comments: There's some Australian slang you wouldn't hear in California bleeding through. Recommended for LCypherED's grasp on characterization, like woah. Thought this fic could be tagged as dark. But compared some other fics, Conspiratheory is sunshine and rainbows, even with the decapitation. Although to be fair, that head didn't stay dead.

  • Synopsis: (or, "Unnatural Deeds Doth Breed Unnatural Troubles"). The year is 1892 and strange events find Stanley Pines in the Oregon frontier, checking on the current state of his estranged brother. But not all is as it seems in the settlement of Gravity Falls, and his twin appears to be stuck in the heart of it. Things escalate quickly, and the question Stan now faces is if he can unravel the secrets spun around him quickly enough to prevent a tragedy.
  • Comments: Firstly, warnings must be given for suicidal ideation, violence, and depictions of anxiety. This story is, at the most basic description, what would happen if Jekyll and Hyde, Gravity Falls, and Macbeth all had a beautiful baby together.

  • Recommended by Hatted Halfling
  • Status: Ongoing
  • Synopsis: Thirty years ago, Stanley Pines made a deal. Now, in the wake of Bill's defeat and his brother's disappearance, Ford begins to unravel Stan's secrets.
  • Comments: This fic is a variation on the Neverhuman AU by notllorstel on Tumblr, done both with notllorstel’s permission and before they had revealed certain details of that AU, making it technically an AU of an AU. Please don’t let that put you off, though, because this fic is AMAZING! It really captures the mystery, supernatural, and over-arching themes of family from the original show, all to the extent that there were times I was at least mildly certain that the author was somehow in contact with Alex Hirsch. Confusing at first due to lack of reader knowledge, it draws you in, with more and more details being added each chapter, with a thrill of excitement and terror as it becomes clearer and clearer that Stan really ISN’T what he seems. This fic is almost complete, we’re just missing the last chapter. Definitely worth reading, though, and, amazingly enough, currently stopped at a point that won't leave you with the desire to strangle the author for stopping there. Though the last chapter would definitely be nice, there's still a few things left to sort out.

Ursa Geminids by George James Valtom.
  • Recommended by lego_joker

  • Synopsis: After the brutal deaths of their parents, the Pines twins cling to each other as they fight a hostile world. Between Dipper's cunning and Mabel's charisma, they've come to dominate their foster home and middle school - until one day, their great-uncle shows up and takes them under his wing. Now a whole new playing field has opened up for them.
  • Comments: Long story short - the best takes on the Mirror Universe Reverse Falls AU I've read so far. Dipper and Mabel are cunning, violent, and borderline sociopathic, but it's not without reason, and their (familial) love is just as strong, if not stronger. Features numerous clever remixes of canon adventures, culminating in ( the kids willingly summoning Bill... at which point they promptly kill him and steal his power). If there's one flaw to be found it's that the kids border on Villain Sue at times, facing few genuine threats (Gideon and Pacifica, while heroic, are side-characters and mostly ineffectual), but if you just want to kick back and watch them go to town on... well, everyone...
