Obviously, the main characters are Bill and Dipper. Bill is a powerful and often malevolent character in the Gravity Falls universe. Dipper is the curious and adventurous young boy. In this fanfiction, their relationship takes a very unique turn with Bill making Dipper his queen.
Well, apart from Bill and Dipper, Mabel could also be an important character. Since Dipper is her twin brother, she would surely be affected by this strange situation where Dipper becomes Bill's queen. She might try to rescue Dipper or at least understand what's going on. Also, other characters from Gravity Falls like Soos or Wendy could potentially play roles in this fanfiction, perhaps as allies or bystanders to Dipper's new situation.
Well, it could be about Bill having some strange and powerful reasons to choose Dipper as his 'queen'. Maybe he sees Dipper's unique qualities like intelligence or a special connection to the supernatural world in the Gravity Falls setting. He might then use his otherworldly powers to transform Dipper into a sort of queen - perhaps giving Dipper powers or a new status that comes with responsibilities and challenges in this fan - created world.
The main characters interacting with Dipper would include Mabel, who would be very curious about what Dipper can do with the powers. She'd constantly be asking him to show off new tricks. Ford would be the one trying to keep Dipper in check and make sure he doesn't go down a dark path with the powers. Then there's Stan. Stan would be a bit skeptical about Dipper having these powers at first. He might think Dipper is getting in over his head. But as time goes on, he'd start to see the potential good that Dipper could do with the powers, like protecting the Mystery Shack from supernatural threats. And of course, the Manotaurs might show up, seeing Dipper as a powerful being and either challenging him or trying to befriend him.
Dipper is sure to be a main character. As for Bill's gang, it could include Bill Cipher, who is the mastermind behind most of the chaos. There might also be some of his minions like Pyronica or Keyhole. These characters would interact with Dipper in various ways, creating the drama and action in the fanfiction. For example, they could be trying to capture Dipper or deceive him in some way.
Dipper is often the more cautious one. He's driven by his curiosity but also his sense of right and wrong. So in time travel scenarios, he might be trying to ensure that the timeline doesn't get too messed up. For example, if they travel to the past, he'd be the one warning Bill not to do things that could have major negative consequences.
He could start by checking some popular fanfic websites like Archive of Our Own (AO3). It has a vast collection of fanfics from various fandoms. Just use the search function and type in relevant keywords like 'Queen Dipper' and maybe Bill's name if it's part of the fic's title or tags.
The two main characters are Dipper and Bill. Dipper is a curious and adventurous kid who often finds himself in strange situations. Bill, on the other hand, is a powerful and often malevolent entity. Their interactions are central to the fanfic, especially when it comes to Bill's actions towards Dipper's family.
One aspect that can make it unique is the exploration of an unusual relationship between Bill and Dipper. It can take the dynamic of their interactions in the original work and twist it in new and unexpected ways.
Obviously, Bill could be the main antagonist. Since he's the one who turns Dipper into a girl, he's likely up to no good. His motives are usually self - serving and evil, so he would probably be causing more trouble for Dipper and the other characters in Gravity Falls.
He should keep checking the fanfic sites regularly. New fics are uploaded all the time. He can also set up alerts on some of the sites if they have such a feature. For example, on AO3, he might be able to set up an alert for any new fics with the 'Queen Dipper' tag. And he could expand his search terms a bit. Maybe there are similar fics with slightly different titles or tags that he hasn't thought of yet.
The contrast between the two characters. Dipper is a curious and somewhat naive kid, while Bill is a chaotic and powerful demon. This creates an interesting dynamic in fanfiction. Writers can explore how their personalities clash or, in some cases, how they might develop an unexpected bond.
