How would Harry and Dudley's personalities change as adults in fanfic?

Harry could become more relaxed. After all the battles and traumas of his youth, as an adult he might be more at peace. He could be less impulsive and more calculating. Dudley, having matured, might lose his bullying nature completely. He could be more empathetic, especially after experiencing some hardships in his own life that made him realize how his actions affected others.

Harry might become more open and less guarded. Since he now has a brother in Dudley, he might feel more at home in the Muggle world. Dudley, on the other hand, could become less of a bully. The knowledge that he has a wizard for a brother could make him more humble and empathetic.

Well, Harry and Dudley's relationship would change drastically. Harry, by adopting Dudley's child, is taking on a huge responsibility. Dudley might initially be in denial about the whole situation, but as time passes, he realizes that Harry is providing a better life for his offspring. This could lead to a thaw in their long - standing animosity. Harry might start to view Dudley as someone who has made mistakes but is also trying to do right by his child in his own way. And Dudley could start to view Harry as a real family member, someone he can rely on.

It could completely transform their relationship. If they have a positive reunion, they might become friends. They could start to support each other in different ways. Harry could use his magic skills to help Dudley out in small ways, like fixing something around his house without Dudley knowing it was magic. Dudley, in return, could offer Harry some insights into the Muggle world that Harry might not be fully aware of.

In some fanfics, they might become reluctant allies. As adults, they could have grown out of their childhood enmity. Maybe Dudley has seen the real threats in the wizarding world through Harry's experiences and realizes they need to work together for the greater good.

Their relationship could evolve positively. Dudley could have grown out of his mean - spirited ways and become more empathetic. He might be in awe of Harry's wizarding abilities now. Harry, seeing Dudley's change, would be more open to him. They could start to support each other, like Dudley helping Harry with Muggle - related things and Harry protecting Dudley from any magical threats.

Naruto's usually boisterous and positive personality might become more brooding as a Hollow. His confidence could turn into overconfidence bordering on recklessness due to the new power he has. He might also be more prone to anger as the Hollow instincts kick in. Hinata, who is typically shy and gentle, could become more withdrawn and secretive. The change into a Hollow might make her fear her own new self, and she might try to hide it from Naruto at first. But as time goes on, she could become more assertive in a different way, using her Hollow powers to protect Naruto instead of just relying on her ninja skills.

In some fanfictions, they might become grudging friends. As adults, they could start to understand each other's past traumas better. Dudley, having grown up and away from his parents' influence, might realize how unfairly he treated Harry as a child. Harry, on the other hand, might see Dudley's attempts at change and begin to trust him more.

In a body - switch scenario, Harry in Hermione's body would probably have his personality shift towards being more detail - oriented. He'd pay closer attention to the little things, like Hermione does when she's studying spells or researching. He might also become more critical of himself in terms of academic performance. Hermione in Harry's body, though, would gain a bit of Harry's recklessness. She'd be more willing to take risks without fully thinking through the consequences. But at the same time, she'd still retain her intelligence, so she might use it to calculate risks better than Harry usually does. This switch of personalities could lead to some really interesting character interactions and growth throughout the fanfiction.

Harry might become more cautious. With Draco as his brother, he'd be exposed to Slytherin - like thinking more often. He could start to weigh his actions more carefully and think about the long - term consequences. Draco, on the other hand, might become a bit more empathetic. Growing up with Harry, he'd see the Gryffindor values up close and might start to care more about others.
