If the sister has a romantic relationship with one of the characters, it can add a whole new dimension to the plot. Love triangles can form, causing jealousy and tension among the characters. This can also drive character development as they have to navigate their feelings while dealing with the greater threats in the wizarding world, like the ever - present danger of the Death Eaters.
It can greatly affect the plot. For instance, if Harry is female, the way Voldemort views her could be different. He might underestimate her in some ways or be more intrigued by her. This could change the sequence of their confrontations. Also, if Hermione is male, his friendship with Ron and Harry could have new tensions. Maybe he'd be more competitive with Harry, which could lead to different sub - plots within the story.
It can completely change the direction of the plot. For instance, if Harry absorbs the Horcrux early on, he may have to face different challenges than in the original story. He might become a target for both sides, as the good side could be wary of his new, Horcrux - influenced state, and the bad side might see him as a threat to Voldemort's power.
Often, the sister is depicted as having a similar mischievous streak as Loki. For example, she might play pranks on the other Asgardians, but with a different motivation. Maybe she does it to get attention or to prove herself in a male - dominated society like Asgard.
The existence of a sister in fanfiction could have a profound impact on Harry Potter's character development. Firstly, it could make him more family - oriented. In the original story, his family situation was quite complex with the loss of his parents. Having a sister would give him a closer family bond. He might become more nurturing, trying to provide for her and teach her about the wizarding world. Secondly, it could affect his self - perception. He might see himself as not just an orphaned hero, but also as a brother. This new role could make him more confident in some ways and more humble in others. He may be more confident in his ability to protect and care for someone, but also more humble as he realizes he has more to lose now. Overall, his character would be more rounded with the addition of a sister in the fanfiction.
The sister's character could be developed as a strong - willed individual. For example, if she was raised in a difficult situation, like in an orphanage in the Muggle world, she could have a tough exterior but a kind heart. She might be initially distrustful of the wizarding world when she discovers it, but as she learns more about her family and the fight against Voldemort, she becomes more open - minded and determined to help.
Some fans might be very disappointed as Ginny and Harry had a much - loved relationship in the original books. It could lead to a lot of debate within the community, with some fans strongly against such a plotline and others being more open to exploring different and darker aspects of relationships.
Another aspect is the friendships. Hermione and a female Harry might have a different kind of friendship. They could bond over more female - centric experiences, like dealing with the boys at Hogwarts in a different way. And Ron's relationship with a female Harry could also be different, perhaps more protective or having a different dynamic altogether, which would then ripple through the entire plot of the story.
It can make the story more intense. A pissed - off Harry Potter is likely to take more drastic actions. For instance, he might be more aggressive in his fight against the dark forces, which can drive the plot forward quickly.
Well, it can completely change the story arc. Since Harry is a central figure, if he's uncaring, the whole fight against Voldemort could be affected. He may not be as motivated to seek out Horcruxes or train for battles.
Well, it changes the plot in many ways. For example, Hermione having a connection to the Marauders means she has access to a whole different set of knowledge and relationships. This could lead to different ways of dealing with Voldemort, like using some of the Marauders' old secrets or contacts.
