Well, 'Gravity Falls: The Lost Legends' is a great fanfiction. It takes the elements of the original show and expands on them in new and exciting ways. It has great character development and plot twists. Also, 'When Gravity Falls Backwards' is a unique fanfic that plays with the concept of time and space in the Gravity Falls world, making for a very engaging read.
One popular Gravity Falls fanfiction is 'The Transcendence of Bill Cipher'. It offers a different take on the character of Bill Cipher and his relationship with the other characters in the Gravity Falls universe. There are also stories that focus on the relationship between Dipper and Wendy, like 'Dipper and Wendy: The Next Chapter' which imagines what could happen between them after the events of the show.
One interesting Gravity Falls fanfiction is 'Dipper's Strange Adventure'. It takes Dipper on a journey that's not part of the original plot but still manages to capture the essence of the show. Another great one is 'Mabel's Magical Day', which focuses on Mabel and her unique experiences in Gravity Falls.
Lemon fanfictions are not in line with the original spirit of Gravity Falls which is a family - friendly show. So instead, I would recommend looking for fanfictions that explore the mystery aspects of the show, like those that expand on the secrets of the Journal or the backstories of the characters like Stan and Ford. These types of fanfictions can be really engaging and stay true to the essence of the series.
There could be Gravity Falls adult fanfiction that delves into the deeper relationships between the characters. For example, stories that expand on the friendship between Dipper and Mabel as they grow older and face new challenges in their adult lives. But again, different writers have different interpretations and styles.
One popular 'Gravity Falls Billdip fanfiction' is 'The Enchanted Bond'. It delves into a unique relationship between Bill and Dipper. Another is 'Bill's Influence' which shows how Bill affects Dipper's journey in the Gravity Falls world in unexpected ways.

One great Gravity Falls fanfiction could be 'The Unseen Adventures in Gravity Falls'. It might explore what happened during the times not shown in the series. Another could be 'Beyond the Mystery Shack', which delves deeper into the secrets around the Shack and its inhabitants. There are also those that focus on the characters' backstories, like a fanfic about Stan's early days in Gravity Falls.

One popular plot could be a character from Gravity Falls being kidnapped by a mysterious creature from the forest. For example, Dipper might be taken by a strange, unseen force while exploring an uncharted area. The story could then focus on Mabel's quest to rescue him, with her enlisting the help of Grunkle Stan and Soos. Another plot could involve a tourist in Gravity Falls being kidnapped by the gnomes. The gnomes might mistake the tourist for a potential 'queen' and hold them captive until the Pines family intervenes.
One popular theme is her redemption arc. Since she starts off as a bit of a snob in the show, many fanfictions explore how she becomes a more likable and empathetic character.
One theme could be the continuation of the story with the characters all grown up. They might be passing on the knowledge of Gravity Falls' mysteries to the next generation. Also, there could be themes related to the characters' careers. For instance, Ford could be mentoring Dipper in some advanced scientific research related to the anomalies in Gravity Falls. And of course, there could be romantic themes involving the adult versions of the characters, like a more complex relationship between Stan and a new character in town.
