Well, initially, Dipper's personality could take a turn towards the more self - centered side. Bill's powers are powerful and could easily corrupt someone. Dipper might start thinking he's above the rules, a bit like how Bill was. But as he delves deeper into the nature of these powers, he'd start to understand the true cost. His inquisitive nature would still be there, but it would be channeled in a different way. He'd be more interested in the origin and limits of these powers. His relationships would be on a rollercoaster. He might push people away, thinking he's protecting them, but then realize he needs their support to keep his humanity intact while having such dangerous powers. So overall, his personality would go through a major transformation full of twists and turns.
His personality might become more secretive. Since Bill's powers are not ordinary, he might feel the need to hide what he can do from others.
Dipper's personality would likely become more complex. He was always curious and intelligent, but with Bill's powers, he could become a bit more arrogant at first, thinking he can solve all problems easily. However, as he realizes the consequences of misusing the powers, he might become more cautious and introspective. His relationships with his friends and family would also be affected. He might distance himself from them initially out of fear of hurting them with his new powers, but as he learns to control them, he could grow closer again in a different way.
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.
Well, perhaps he'd start to have a more chaotic view of the world. He might be tempted to use the powers for his own gain at first, like getting rid of his daily chores or getting better grades easily. But then he'd realize the great responsibility that comes with such powers and struggle to keep them in check.
Well, Dipper might start causing chaos just like Bill. He could use his new powers to play pranks on Mabel, like turning her sweaters into strange, living creatures. Or he could use the power of mind - reading to know what everyone in Gravity Falls is thinking, which would lead to some really awkward and funny situations.
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.
In a 'Dipper Gets Bill's Power' fanfiction, Dipper might first struggle to control the power. He could accidentally cause chaos in Gravity Falls, like making objects float uncontrollably or distort the space - time continuum a bit. Maybe he'd start seeing the world from Bill's strange, other - dimensional perspective.
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.
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.
Well, in this 'dipper is bill's pet fanfiction', it could involve a lot of creative elements. Maybe it shows how Dipper's life changes when he becomes Bill's pet. It could be about the power dynamics between them, with Bill being some sort of powerful entity and Dipper in this subservient 'pet' role. There could also be elements of adventure as Dipper tries to navigate this new and rather odd situation.
In some fanfictions, Bill might become more cautious. After experiencing the horrors of war, he'd be more aware of the potential dangers around every corner. So he could be more hesitant when it comes to taking risks.
One might expect a lot of drama. Since Bill is a rather chaotic and powerful character, his child would likely bring a whole new level of trouble or potential. Dipper, on the other hand, is a more relatable and 'human' character, so her pregnancy could show her growth and how she copes with this unexpected situation.
