Why are 'Gravity Falls Mabel x Bill' fanfics so popular?

Well, there's a fanfic called 'Mabel and Bill: An Unusual Alliance'. In this one, Mabel finds herself in a situation where she has to team up with Bill to save Gravity Falls from a new, greater threat. It has a really interesting plot with Mabel constantly trying to keep Bill in line while they work together. Then there's 'Bill's Interest in Mabel', which delves into why Bill seems so fascinated by Mabel and how she reacts to his attention.

One common theme is the exploration of the 'opposites attract' concept. Bill is this powerful, otherworldly and often malevolent being, while Mabel is a sweet, innocent and positive girl. Their interactions based on these contrasting natures are often explored. Another theme is the idea of the unexpected. Their relationship is not something that one would expect in the normal Gravity Falls storyline, so fics often play with this element of surprise.

One possible fanfiction could be where Bill Cipher tries to deceive Mabel in a different way than in the show. Maybe he appears to her in a dream, offering her the world's greatest collection of sweaters in exchange for a small favor that's secretly a big deal. But Mabel, being clever, starts to suspect his motives and tries to outwit him using her unique charm and creativity.

One great fanfic could be 'The Bond Beyond Differences' where Mabel and Pacifica start off as rivals but gradually discover their shared interests and form a deep friendship that might turn into something more. It has really well - written character interactions.

They also often have great plotlines that involve their relationship. It could be about how they support each other through difficult times or how they have adventures together. Many good fanfics will also include elements from the original show, like the strange creatures and mysteries of Gravity Falls.

The character development is another factor. Fans enjoy seeing Dipper grow and change as a result of his encounters with Bill. And for Bill, there could be a change in his motives or his view of Dipper. These fanfictions allow for a deeper exploration of their personalities that we might not have seen fully in the show.

One popular 'Gravity Falls Bill x Mabel fanfic' is 'The Strange Bond'. It delves into the unique relationship between Bill and Mabel in a really interesting way. It shows how their interactions can be both mysterious and somewhat endearing. Another good one is 'Bill's Fascination with Mabel'. This fic focuses on Bill's rather unusual interest in Mabel and how it unfolds throughout the story.

The theme of redemption can also be found in some of these fanfics. Bill, being a somewhat villainous character in the original, may be on a path of redemption in some stories, especially through his relationship with Dipper. Also, the theme of self - discovery is common. Dipper discovers new aspects of himself through his interactions with Bill.

One way a fanfiction could go is that Bill Cipher is actually trapped in a form that only Mabel can see. He needs her help to break free, but Mabel is hesitant. She doesn't trust him at all. Bill Cipher then tries to convince her by showing her glimpses of things she desires, like the future with all her friends happy and her having amazing adventures. But Mabel has to decide if she can really trust Bill Cipher or if it's all just a trick.

There's also 'Adventures of Dipper and Mabel: The Fanfic'. This one takes the characters on new and exciting adventures while still maintaining their core personalities. It often has Dipper and Mabel relying on each other, just like in the show. For example, there are parts where Dipper uses his logical thinking and Mabel her creative ideas to get out of tricky situations.
