Well, if James is a Death Eater in fanfiction, it completely alters the dynamic at Hogwarts. James would no longer be part of the group fighting against Voldemort. This would mean that many of the events that happened because of the Marauders' resistance to the Death Eaters wouldn't occur. For instance, the creation of the Marauder's Map might not have been for good reasons. And Lily's relationship with James would be much more complex. Maybe she was initially trying to save him from the dark side, but failed.
A fanfiction with James as a Death Eater changes the original storyline in numerous ways. Firstly, the whole idea of Gryffindor values is challenged. James, as a Death Eater, would be going against everything Gryffindor stands for. This could lead to a different perception of the Hogwarts houses in general. Secondly, Harry's journey would be completely different. He might not have the same support system that he had in the original story. The friendship between his father's friends might not exist in the same way. And the fight against Voldemort would have a whole new dimension, with James on the wrong side, perhaps even being a major obstacle for Harry to overcome.
Well, in the original story, Harry was an orphan who had to figure out his place in the wizarding world on his own. But in 'Death Adopts Harry Potter' fanfictions, he has a very different kind of guidance. Death can offer him insights into magic that no one else could. For example, he might learn how to manipulate death - related magic, which could give him an edge against Voldemort. It completely changes the power dynamics.
In such fanfictions, the lack of parental support means Harry might form different relationships. For example, he could rely more on his friends or other adult figures like Sirius or Remus in a different way. The dynamic at Hogwarts could also change. Without the influence of his parents' love, he might be more vulnerable to the taunts of his classmates, which could lead to a darker path for his character. He could also be more desperate to prove himself, which might make him take more risks.
The story would be very different. Without being a Death Eater, Snape's role and relationships with other characters would likely shift dramatically.
They often change the story by making Harry's character more morally ambiguous. Instead of being the pure - hearted hero, he might be tempted by the dark side. For example, he could start using some of the dark magic that the Death Eaters are known for.
In the original story, Harry's main concern was the fight against the dark forces. But in a fem Harry Potter marriage law fanfiction, her priorities are somewhat redirected. The law might require her to marry into a certain family to gain political or magical advantages. This could mean she has to make deals and compromises she wouldn't have in the original story. Also, her relationships with other characters like Hermione and Ron would be redefined. Hermione might be more involved in helping fem Harry understand and deal with the marriage law, and Ron might have different feelings if he sees fem Harry being forced to consider other potential partners. All in all, it significantly alters the character dynamics and the overall flow of the story.
The relationship dynamics change drastically. Instead of having that tragic but heroic backstory of his parents dying for him, he has a story of being left behind. This would also change his relationship with Dumbledore. Dumbledore might be more hesitant to trust Harry with the fight against Voldemort as his abandonment could indicate some instability or unworthiness in Harry's character in this fanfiction version.
It changes the storyline by introducing an unexpected ally. Hermione, who was used to seeing Death Eaters as pure evil, now has to reevaluate her views. This can lead to new alliances and different ways of fighting against Voldemort. For example, she might use the Death Eater's inside knowledge of Voldemort's plans.
One possibility could be that in this fanfiction, James Potter's fall to the dark side as a Death Eater creates a complex and tragic dynamic with Lily, the Auror. Maybe there are intense battles between them where their past relationship adds an extra layer of emotion. It could explore how their different paths change their views of each other and the wizarding world.
It adds a new type of creature. The werepire concept changes the magical world by introducing a different kind of threat or ally. Harry might have to face different challenges related to this new entity.
Well, it completely changes the setting. Instead of Hogwarts and the wizarding world of Britain, he's now in Kuronu. This means different magical rules, different cultures, and different relationships. His skills and knowledge from the Potter world may or may not be applicable in Kuronu.
