A plot could involve a prophecy that states Bill and Dipper must marry to save the world from a great danger. At first, they are reluctant as they have their own issues to deal with. Dipper is worried about his future and studies, while Bill has his own power - related concerns. However, as they start to work together to figure out how to fulfill the prophecy, they develop feelings for each other. They end up getting married not just to save the world, but also because they have fallen in love.
Perhaps Bill, who has changed his ways a bit, tries to court Dipper in his own unique way. He shows Dipper different dimensions and secrets of the universe that only he can access. Dipper is initially hesitant but is drawn to Bill's charm and the mystery he represents. As they get to know each other more, they find that they complement each other well, and getting married seems like the natural next step for them. Their relationship could be a symbol of two different worlds coming together.
One possible plot is that they are recruited into a secret Suicide Squad - esque team to stop an impending apocalypse. Bill could see it as an opportunity for his own gain, while Dipper is more focused on saving the world. Along the way, they encounter strange creatures and difficult moral choices. Their interactions with the other members of the squad, if there are any, would also add to the complexity of the story.
One possible plot could be that Mabel and Dipper get trapped in a strange game world created by Bill. Bill, being his mischievous self, tries to manipulate the rules of the game to turn Mabel and Dipper against each other. But their strong bond of love for each other as siblings helps them see through Bill's tricks and they start to find ways to turn the tables on him within the game. Maybe they use the power of love, which is something Bill doesn't understand, to break free from the game world and defeat Bill once and for all.
Dipper would likely start as a curious and somewhat naive character. As he gets closer to Bill, he would become more confident in himself and his decisions. He might learn to be more accepting of the strange and unusual. Bill, on the other hand, could start as a rather self - centered entity. But through his relationship with Dipper, he would develop empathy and a sense of responsibility. He would become more attuned to Dipper's feelings and needs.
Well, in a 'bill obsessed with dipper fanfic', it might focus on Bill's unwavering attention towards Dipper. It could show how Bill, being a powerful and often menacing character, becomes so fixated on Dipper that it disrupts the normal order of the story's world. For example, Bill might be constantly trying to draw Dipper into his own chaotic realm, while Dipper is trying to resist. This could lead to all sorts of adventures and challenges for Dipper as he tries to outwit Bill and protect himself and his friends.
One possible theme could be identity. With Dipper being female in this fanfic, she may have to re - evaluate her own identity and how she fits into the story's world. Another theme might be power dynamics. Bill is a very powerful entity, and a female Dipper's relationship with him could explore different power balances. It could also have a theme of mystery, as Bill is full of secrets and a female Dipper might be more determined to uncover them.
Another aspect could be that Bill's transformation of Dipper into a girl has some unforeseen consequences. It could be that there is a magical imbalance in the Gravity Falls world as a result. Dipper, in his new form, might discover new powers or abilities that he has to learn to control, all while trying to find a way to reverse the transformation and stop Bill's machinations.
One possible theme could be the struggle between good and evil. Dipper represents the more good - natured side, while Bill Cipher is clearly evil. Their interactions might explore how Dipper resists Bill's temptations or attempts to manipulate him. Another theme could be the exploration of the unknown. Bill comes from a strange and otherworldly place, and Dipper's curiosity might lead him to delve deeper into Bill's world, with the 'lemon' perhaps symbolizing the sour or difficult aspects of this exploration.
Well, perhaps it's a story where Dipper gets caught up in Bill's gang's evil plans. They might try to manipulate him into doing their bidding, but Dipper uses his wits to outsmart them. The plot could involve Dipper having to navigate through a series of dangerous situations created by Bill's gang, all while trying to protect his friends and the town he loves.
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.
In such a fanfic, Bill Cipher might try to trick Dipper and Mabel. He could offer them false knowledge or tempt them with strange powers. Maybe Dipper would be the first to suspect Bill's motives, while Mabel might be more easily swayed by his charm at first.
