Yes, there are quite a few. One popular one might show Dudley seething as he sees Harry and Ginny's relationship grow. He could be jealous because Harry has always been in the spotlight in a way, and now he has a loving relationship too. It makes Dudley feel even more left out.
Definitely. In certain fanfictions, Dudley's jealousy of Harry stems from the fact that Harry has a group of loyal friends. Dudley, on the other hand, might not have such deep and meaningful relationships. Harry's friends would do anything for him, and they share in his adventures. Dudley, seeing this, feels left out and jealous. He wishes he had that kind of bond with someone, and his envy towards Harry grows as a result.
The theme of envy is also very prominent. Dudley envies Harry's connection with Ginny, which is often portrayed as deep and loving. He may also envy the magical world that Harry and Ginny are part of, which adds another layer to his jealousy. Another common aspect is Dudley's struggle to come to terms with his own feelings, as he's not used to feeling so envious.
Well, perhaps Dudley uses his street - smart knowledge. He might teach Harry some rough - and - tumble moves he's learned from his own scuffles in the neighborhood. For example, showing Harry how to dodge a punch quickly.
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.
I'm not sure if there is a specific 'Dudley Gets Harry mpreg fanfiction'. Fanfiction covers a vast range of ideas and pairings, but this one seems rather unusual. It might exist in the extremely diverse world of fan-created works, but it's not a common or widely - known type of fanfiction. You could try searching on specialized fanfiction websites to find out for sure.
Maybe Dudley sees a different side of Harry through fanfiction. He might be curious about the magical world from Harry's perspective that he didn't fully understand before. Fanfiction often explores characters in new and interesting ways that could intrigue Dudley.
In this fanfiction, they might start to become more like friends. Since Harry is helping Dudley eat better, there's a sense of care and concern that could be building a new bond between them.
It could be that Dudley has his own reasons to oppose the dark forces that are after Harry. He might see that if Harry fails, it could also mean trouble for him and his family. So, he decides to train Harry to fight as a way of self - preservation as well as helping Harry. Another reason could be that Dudley has grown to respect Harry over time and wants to contribute to Harry's ability to defend himself against the many threats he faces.
Sure. Fanfiction often takes the existing characters and situations and twists them. For Harry and Dudley, it could start with a shared experience that makes Dudley realize Harry isn't so bad. Maybe they get caught up in a magical adventure together outside of the normal Hogwarts - related stuff. This common experience could break down the barriers between them and start a friendship.
