There might be a plot where Harry outperforms Hermione in a magical duel. His unique spellcasting skills and his ability to improvise in combat could be highlighted, showing that he is better in that aspect.
One possible plot development could be the initial shock and confusion for both Harry and Hermione. They would have to deal with the reactions of their friends, like Ron, who might be very surprised or even a bit jealous. Then they'd need to figure out how to balance their new situation with their fight against Voldemort or other magical threats. Another aspect could be how they prepare for the baby, from finding a safe place to live to getting all the necessary baby supplies in the wizarding world.
Well, one aspect could be his courage in the face of danger. Harry often jumps into dangerous situations without hesitation, while Hermione might overthink and be more cautious. For example, in battles, Harry's quick instincts make him act faster to protect others.
Well, one possibility could be that they start sharing magical knowledge more often. Since they're neighbors, it's easier for Hermione to drag Harry to her place to study new spells or potions. Another could be that they team up to deal with local magical nuisances, like a poltergeist that's causing trouble in their neighborhood. And they might also end up introducing each other to their respective Muggle and wizarding families more frequently.
Often, fanfictions that claim Hermione is Voldemort's heir will create some convoluted backstory. For example, they might say that there was a secret affair between a distant relative of Hermione's and one of Voldemort's ancestors. This would then be used as the basis for her being his heir. However, this is pure invention for the sake of the fanfiction and has no basis in the real Harry Potter story. The original story has no such indication, but fanfiction allows for these wild and imaginative ideas to be explored.
There is no evidence to support such a heinous claim in fanfiction. Fanfiction is often a work of wild imagination by fans, and making such false and serious accusations within it is unacceptable. It goes against the positive and creative nature of fan - created works.
There is no evidence at all. J.K. Rowling started writing Harry Potter on her own, with her own imagination. The series has a clear origin story, from her coming up with the idea of a boy wizard to building the entire wizarding world. Fanfiction usually builds on existing works, but Harry Potter is the original source, not the other way around, especially not related to something as unclear as 'belloch' fanfiction.
One possible plot development could be that Dark Harry has some ulterior motive for kidnapping Hermione. Maybe he wants to use her knowledge to further his dark plans. For example, Hermione is known for her intelligence and vast knowledge of magic, and Dark Harry might force her to help him find a powerful and dark magical artifact.
One interesting plot development could be the confusion it causes among their friends. Harry, in Hermione's body, might struggle with her academic routines and the way she approaches studies. Meanwhile, Hermione in Harry's body has to deal with the pressure of being the 'Chosen One' and facing Voldemort. For example, when Harry tries to answer questions in class as Hermione, he might not be as quick or accurate, leading to some humorous moments. Also, Hermione in Harry's body could use her intelligence to come up with new strategies against the Dark Lord that Harry might not have thought of before.
One possible plot development could be that Hermione is left with a deep sense of guilt and responsibility. She might then take on Harry's mission or cause in his memory. For example, if they were fighting against a new dark wizard, Hermione could become even more determined to defeat the enemy.
It could also be that Hermione, after being abandoned, decides to leave Hogwarts for a while. She travels to different magical places, perhaps some ancient wizarding libraries or hidden magical communities. There, she meets Draco Malfoy who is also on some sort of self - discovery journey. At first, they are both hesitant around each other, but as they share their experiences and knowledge, they start to form a bond.
