In 'Dipper Gets Possessed Fanfiction', the most likely possessing entities are often related to the lore of Gravity Falls. Bill Cipher is a top candidate, as he's always looking for ways to cause chaos. But there are other options too. It could be a forgotten god from the native legends of the area. These gods might have been dormant for a long time and see Dipper as a vessel to reassert their power. Additionally, a magical experiment gone wrong could result in Dipper being possessed by some sort of unstable magical energy that takes on a life of its own.
Well, it could be a vengeful ghost. Maybe there's a spirit with a grudge against the Pines family, and Dipper is an easy target. Also, a cursed object might be the cause. Dipper could have come across an old artifact in his explorations that contains a possessing entity. Or, in some fanfictions, it could be an alien intelligence. Gravity Falls has had some strange encounters with the extraterrestrial, and an alien could possess Dipper to study or use him for their own purposes.
One of the most likely possessing entities could be Bill Cipher. He's a powerful and malevolent being in the Gravity Falls universe, and he has shown an interest in Dipper before. Another possibility is an ancient spirit or demon from the forest around Gravity Falls. The forest is full of mysteries, and it's not hard to imagine some dark entity lurking there that decides to possess Dipper.
Well, a frequent theme is the change in Dipper's personality. When possessed, he could become more aggressive or withdrawn, which creates a contrast to his usual curious and determined self. There may be a theme of redemption too. If Dipper does something bad while possessed, the story could be about him making amends once he's free. And sometimes, the fanfiction might use the possession as a way to introduce new powers or abilities that Dipper has to learn to control.
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.
Obviously, Dipper is the main character as the title implies. His sister Mabel is often included too. She might react in various ways to Dipper getting powers, like being excited or a bit jealous. Wendy is also a common character. She could be a source of support or a love interest for Dipper in some fanfictions.
Harry Potter is central as the possessed. Voldemort is crucial as the possessor. Harry's friends are bound to be main characters. Hermione, with her intelligence, would be constantly observing Harry's strange behavior and coming up with theories. Ron, being Harry's loyal friend, would be by his side and ready to fight for him. Also, characters like Sirius Black, if he's still alive in the fanfiction's timeline, could be involved. He has a close connection to Harry and would surely want to help him get rid of Voldemort's control.
Dipper might become more confident, almost to the point of arrogance at first. After all, he now has a great deal of power at his fingertips. But deep down, he'd still be the same curious and somewhat nerdy Dipper, just with a new - found sense of self - importance.
Dipper would probably have a hard time at first. He's used to the outdoorsy and somewhat spooky Gravity Falls. Ouran High School is all about luxury and socializing. But he'd adapt by using his intelligence. He'd start to figure out the unspoken rules of the school, like how to interact with the different types of students in the Host Club. Maybe he'd start by observing quietly and then gradually get more involved.
Another plot might involve Dipper having to keep his powers a secret from his family and friends at first. He struggles with this as he tries to figure out how to control them without raising suspicion. For example, he accidentally makes things levitate when he's around Mabel, and has to quickly cover it up.
Often, it could be fans who are really invested in the Katniss character. People who have been following the Hunger Games series closely and have a deep understanding of her character arc. They might be female fans who can relate to the idea of pregnancy and motherhood, wanting to project that onto Katniss. But it could also be male fans who are interested in exploring different aspects of the story and Katniss's relationships through this new plotline.
The Yiga Clan could be likely kidnappers. They've always been enemies of Link and would love to get their hands on him. They might see kidnapping him as a way to stop him from interfering in their plans. Another possibility is the Gerudo thieves. Although not all Gerudo are bad, there could be a group of them who think Link has something valuable and decide to take him hostage.
It could be the traditional villains from the original story. Maybe some of the old enemies of Percy who have a vendetta against him. For example, the Titans or some rogue demigods who oppose him for power or personal reasons.
