[COMPLETED] Gravity Falls (semi-original) Triplet!AU, inspired by the fanart and comics created by doublepines Imagine if Tyrone hadn't died at the end of the episode, Double Dipper, how would the twins' lives had changed? After four years of feeling like the runt of the family, Tyrone (aka Ty) Pines finally gets his opportunity to visit the not-so well known town of Gravity Falls, the one topic that his siblings can't seem to stop talking about. While staying in town, Ty writes about his many adventures that include uncovering a dangerous secret, dealing with a love triangle and finding himself mixed up in some good old fashioned sibling drama. Can Ty juggle it all and possibly save the town from its destruction? (. . .um, again.) "Gfjwkwkdnamdkskfudunebrjf can't handle the sibling love djfjisjwndns" ~ BrightnessWings19 "Aw cute triplets"~LostGeekLeek "THIS IS REALLY GOOD LIKE I CAN PICTURE IT I ALREADY HAVE A CRUSH ON TYRONE JEEZ CATH" ~-everythingisonfire (Cover art credit goes to DoublePines on deviantart.com) Please keep it clean in the comments, since this is a Fanfiction based on a kids show there's most likely going to be some (even if few) young ages reading this. I keep my fanfictions clean (meaning no cursing) so once again, please do so in the comments. If not the comment will be reported/deleted.

Old fools (Stanford pines x Reader) by patsavouras69

(STORY CONTAINS: STRONG LANGUAGE, VIOLENCE, BLOOD, SUGGESTIVE THEMES, ALCOHOL, VERY VERY DARK THEMES I'LL PUT MORE WARNINGS DON'T WORRY POOKIES) (I do not own Gravity Falls) Stanford and Y/N are old Backupsmore buddies, they did research together until Ford left without telling goodbye, leaving Y/N in the dark about his whereabouts. It's 2013 and you're finally retiring from your job as a biologist, and you decide to move into a small secluded town in Oregon called Gravity Falls; In hopes of resting your brain from countless years of intently studying living organisms. But what you encountered there was FAR beyond what you were hoping for. (Gender-neutral for everyone, post-weirdmageddon, re-entering my gravity falls phase LMAO, art is mine)

Don't leave me (billdip) by FuckYouFoundMe

After a terrible car crash resulting in the death of their parents, 17 year olds Dipper and Mabel Pines are sent back to Gravity Falls to live with their Grunkles. Mabel now hates Dipper, and blames him for the crash, since they were only out getting him his anxiety medication. The Grunkles don't fully agree with Mabels logic, but are still distant with Dipper, for they think he's a freak because of his anxiety. And so in the one place he felt he could truly call home, Dipper was now alone and hated by the "family" that once loved him. One night, Dipper overhears the family talking about how useless he is and, doing the only thing he knows, he runs. He runs out of the house, into the woods, and right into the newly human formed Bill Cipher. *No smut because I'm not good at writing it 🙃 *None of the art in this book is mine, credit goes to the artists *I don't own Gravity Falls or the characters, they belong to Alex Hirsch *dec 8, 2022- gonna read through this and edit it, hopefully make it better :)

Infinite Gravity (Zero Rises) by fallingunDawn

When a pair of twin brothers escape their abusive family, they find themselves in a city named Infinite Gravity, in there Bill finds a mysterious journal with the abilities to change reality and decides to use it to make a better world for him and his brother. But having that power brings to the twins many powerful entities, the local citizens believe those entities are angels, giving them the title of guardians. Some will face them, some will help them, but they should remember that their decisions will either bring hope... or doom them all. This is the Season One of my original/combination AU Infinite Gravity. This story is profanity-clean series, so please don't cuss on the comments. Sit or lay down, grab a snack and a drink and enjoy your reading.

Weirdmegedon was stopped. We won. Dipper and I went back to California and were going to live normal, happy lives. I should be happy. That's what they said. That's what they told me. But I started to notice something was off, someone was there. And he was out for revenge. No one can help me. Not even Dipper. I am alone. Side note: Picture Bill always in human form. And in this version, it starts in the middle of Weirdmeggedon, except Mabel knows the equation to break down the barrier, not Ford. And the twins are 15, not 12. I do not own Gravity Falls or the characters Nor do I own the cover. Warnings: -Strong language used -Depression themes -Anxiety themes -Self harm mentioned -Suicide mentioned -Abuse -Smut (More warnings may be added later. PM me if you think there should be an additional warning)

This story is based off and inspired by the YouTube video 'Sleep - Gravity falls fan animatic' uploaded by 'MonsterBoyTrash' please go watch it and support their channel especially if you like this fanfic as they gave me the idea and inspiration for this au. I really enjoyed this animatic and would like to put my own spin on what happens and how this ends, I hope you enjoy! I will try to upload at least one chapter each week and be consistent, if it's a little longer than a week, don't worry I haven't forgotten, I'm either busy or I have writers block, or both.

When Gravity Falls and Earth becomes Sky by grapesplease

Fear the beast with just one eye. Everyone has a purpose in life. My purpose happens to be a search for a sense of self. This led me to the sleepy town of Gravity Falls Oregon in search of my Grandfather, Stanford Pines. Stanford was a hero to me, we're both so similar to each other, it's like I've finally found a place where I belong. Nothing could ruin this... ** This fic is set in gravity falls the summer after weirdmageddon, it strays a bit from the canon obviously because it's a fanfic, it's not gonna be 100% canon. Bill Cipher will be a major part in this fic bc yass! Mabel and Dipper are 13, the reader is 19 I'm trying to make it as gender neutral as possible but I am a female so low key writing it with female in mind, but anyone can read! It's not gender specific. The reader uses they/them pronouns but you can just sub them for whatever pronouns you want to use 🫶

Let's say that Dipper never went to gravity falls, but everything else still happens. Mabel defeated Bill with the rest of the town. There both 17. Dipper been to multiple hospitals because of his anxiety, depression and suicidal thoughts. Dipper's father has been abusing him for years. Finally they stopped his father and he's in jail. Dipper doesn't trust anyone at all. He doesn't like being touch by other expect for Mabel . Mabel trying to keep Dipper away from bad people. Mabel finds out that Bill is still alive. Dipper is still the kind and loving brother. gives up anything for her no matter what. One day Dipper meets Bill in his human form. the two have been meeting up in secret because of Bill. Dipper things he's a nice guy until Mabel shows up messing everything up. (bitch). Bill slowly starts to fall in love with the young teen and Dipper starts to fall for the demon as well. Note : Warning for suicidal thoughts, self harm and bad language.
