Dipper and Mabel, now seventeen years old, have decided to stay in Gravity Falls with Stan and Ford. Dipper is still the same, a big geek and a bookworm, and Mabel is still crazy and cooky as ever. But what happens when Bill Cipher returns, Mabel gets kidnapped by him, and Dipper takes her place? And when these two become closer, will they fall in love? Or will Gideon, who's now in love with Dipper, stop them? (P.S: I don't own the art or videos in the story! I just thought they'd be perfect for the each chapter!)

After weirdmagedon, Dipper and Mable leave to go home, it's the last day of school all ready and the mystery twins soon find out they are going BACK to Gravity Falls, Or.

Dipper is not exactly a common siren living in the ocean. Her family is curse every other four generations a child is curse. Dipper and her sister are cursed with amazing voices people would die for and fantastic looks. But when the king and prince of the sea come to her village looking for a bride for the prince everyone is excited but her. Some girls her age have already found mates. Mabel was dating mermando. But when she is chosen to be the bride what will happen when she is kidnapped and sold to a land kingdom. Will she return home? --------- I am making this up but go with it. Dipper is a female siren. Mabel is a mermaid. The difference is sirens are carnivores. Mermaids are omnivores (plants and meat). Sirens have two feet longer of a tail than mermaids because sirens tend to strangle their pray while singing, their tail is more snake like while mermaids have a more fish like tail.

Dipper was always a girl, and that as her secret, Mabel knew but understand. But puberty hit her hard and she was not afraid of telling her secret anymore, instead she embraced it. After 4 years away from gravity falls, it was time to come back, but what happen if she meet and unexpected guest?

Contains Mpreg (males getting pregnant) swearing and little violence and lemon/smut. Don't like *points to the front door* THEN GET THE FUCK OUT! I don't own any pictures. And we all know who gravityFalls belong to. ----------------------------------------------------------------- Wolf Au Dipper is his packs most precious wolf. Not only is he male and has special healing powers but could also get pregnant with pups. The only problem, is that he's an omega and often looked down on if a healing doesn't go right or takes longer than expected. What will happen when his pack is attacked?

Ok this is my first billdip AU Dipper is a siren Bill is a ruthless pirate What happens when the two meet? Will they fall in love Or die loving each other

Dipper is the youngest Egyptian princess, all the attention of seems to be towards her twin brother but that all changes when the priests bring a message from the god cipher that he wants dipper as a living sacrifice. Dipper is 17 in this I'm horrible at this. ON HIATUS

What happens when someone you knew... becomes someone, or something else? Sorry, I couldn't help making a fanfic on this AU, I love it so much! And I love GF so why not? Note: Again, I own nothing of the things that you will read (except for the story) Gravity Falls, the cover, and the AU belong to their respective owners.
