I'm not sure if there is such a specific fanfic. Fanfic creation is very diverse, but this seems like a rather unusual and perhaps not very common combination. There are many fanfic platforms out there, but this concept might be a bit out of the mainstream.
Harry would likely start off as a rather arrogant character, given the Malfoy upbringing. He'd look down on those he considered beneath him, like muggle - borns. But as he experiences different things, he could start to question his family's beliefs. Maybe he meets a kind muggle - born witch or wizard who shows him that there's more to a person than their blood status. This could lead to a gradual change in his character, from a pure - blood supremacist to someone who believes in equality.
Yes. In the vast realm of fanfiction, many ideas are explored, and this is one of them. It might seem odd considering the original story, but it allows for new plotlines and character developments. Writers might use this concept to explore how Harry's character would be different if he had been raised in the Malfoy household. Maybe he would have been more influenced by the pure - blood ideology, or perhaps he would have rebelled against it in a different way compared to his journey in the original series.
One interesting aspect in Lucius and Draco Malfoy's father - son relationship in fanfiction could be Draco's struggle to break free from his father's shadow. Lucius, being a strong - willed and somewhat dark - aligned wizard, has always had high expectations for Draco. In some fanfictions, Draco starts to question his father's values after seeing the destruction caused by the Dark Lord. This leads to internal conflicts within him as he tries to decide whether to follow in his father's footsteps or forge his own path.
He becomes more conflicted. Growing up as Lucius Malfoy's son, he is exposed to different values. So, instead of the Gryffindor - like straightforwardness, he may have a more calculating side.
One possible storyline is that Draco rebels against Lucius. Draco, having witnessed the horrors of the wizarding war and the mistakes his father made, decides to turn his back on Lucius's pure - blood supremacist views. He might start to associate with more liberal - minded wizards and witches, causing a rift in their relationship.
One interesting plot could be Harry growing up in the Malfoy Manor and having to deal with the pure - blood ideology from a different perspective. He might struggle between his own sense of right and wrong and the values imposed on him by the Malfoy family.
One reason could be for the greater good of the wizarding world. If Lucius is healed, he might be able to turn away from the Dark side and provide useful information about Voldemort's remaining followers.
Well, in some fanfictions, Harry might use his advanced magic skills he learned from Dumbledore's old books. Maybe he discovers a long - forgotten spell that can reverse the dark magic effects on Lucius.
Well, if Harry was Lucius Malfoy's son, it would completely flip the story. Harry would be brought up in a pure - blood supremacist family. He might not have his kind heart as we know it. His relationship with Ron and Hermione would be non - existent or very different. He would probably be taught dark magic from a young age instead of the values he learned at Hogwarts in the original story.
