The relationship between the Malfoy family and the Weasleys would be very different. Since Hermione is friends with the Weasleys, there could be a strange, new connection between the two families. For example, Draco might grow up with Ron as a sort of family acquaintance, which would change their interactions completely.
The overall plot against Voldemort could be affected. Lucius' actions in the original story were often influenced by his family's pure - blood ideology. If Hermione is his mother, he may not support Voldemort as readily. This could lead to a quicker defeat of Voldemort or a completely different way of fighting against him.
There would be numerous implications. Firstly, Harry's appearance might be different as he would inherit some Malfoy traits. His personality could be more influenced by the Malfoy upbringing, which is often about pride and pure - blood superiority. His friends might also view him differently. Hermione and Ron might be initially suspicious or even hostile towards him. And his relationship with Dumbledore would likely change. Dumbledore would have to approach Harry in a different way, as Harry would now be part of a family with strong ties to the dark side. His magic might also be affected, as he could be taught different spells and techniques within the Malfoy family environment.
One implication could be a huge shift in Harry's identity. He would be part of a pure - blood wizarding family, which would change how others in the wizarding world view him. Also, his relationship with Draco Malfoy would become extremely complex.
Well, it would completely change the relationship dynamics. There would be a huge shock factor for all the other characters. And it would also mean a major shift in the power dynamics between the two families involved.
The implications are numerous. In a fanfiction where Hermione is Lucius' mistress and pregnant, it would be a major deviation from the original narrative. Hermione's relationship with her Hogwarts friends would be strained, if not completely broken. Harry and Ron might feel betrayed. From a magical society point of view, it could cause a scandal. The Malfoy family might also have mixed reactions. Lucius' wife Narcissa might be furious, and Draco would have to deal with this new family situation. And Hermione herself would have to struggle with her own identity and the choices she's made, as well as the consequences of her pregnancy in a world full of magic and danger.
One implication is that it would completely change Hermione's backstory. Instead of being a Muggle - born witch, she would now have a pure - blood family connection. This could lead to a different perception of her among the wizarding community.
Well, it could be really strange for him. He might find some of the interpretations of his life and adventures quite off - putting or amusing. Maybe he'd be shocked to see how some fans have romanticized his relationships in ways he never thought of.
Hermione's status at Hogwarts might change. She could have more privileges or face different expectations. For example, McGonagall might be more protective of her, which could lead to different interactions with other students and teachers.
It's hard to say for certain. The Harry Potter fanfiction community is vast and diverse. Some writers like to create alternative universes where characters have completely different relationships. But given the nature of Harry and Lucius in the original series - one being the hero and the other a Death Eater - making them brothers would require a great deal of imagination and explanation. The writer would need to explore how this new relationship would affect the plot, the other characters, and the overall themes of the story. It might also change the way we view the magical world's social and political structures as they are presented in the books.
For one thing, Hermione's status in the wizarding world would be very different. She would no longer be just a muggle - born witch, but a Malfoy. This would change how others view her. The Death Eaters might have a different attitude towards her, and she might be in the middle of the fight between the good side and her father's side. Also, her academic achievements might be seen in a new light, perhaps as a way to prove herself worthy to both her newfound family and her old friends.
It also shows the freedom and diversity in fanfiction. While it might not be in line with the original spirit, it allows for different creative ideas to be explored. However, it can cause some division within the fan community between those who support this new take and those who firmly oppose any deviation from the original relationships.
