Another aspect could be social status. Lucius is very much concerned about the family's social standing. Hermione, being Muggle - born, is not part of the traditional pureblood society that the Malfoys are so deeply entrenched in. A baby from such a union would likely face discrimination and scorn from their own social circle, and Lucius wants to avoid any such blemish on the family name.
Lucius might disapprove because of the political implications. The Malfoy family has long - standing political alliances within the wizarding world. A relationship with Hermione, who is often seen as a symbol of the more progressive, Muggle - friendly side, could disrupt their carefully crafted political position. And having a baby would make that connection even more permanent and visible, which Lucius would not want.
Hermione, being the intelligent and strong - willed witch she is, could try to reason with Lucius. She could point out how their baby could be a bridge between the Muggle - born and pureblood worlds, bringing new perspectives and opportunities. Maybe she could show him that the baby has the potential to be a great wizard or witch regardless of its heritage.
Lucius' power within the dark wizarding world could be intimidating to Draco. He has connections, influence, and a certain level of magical ability. Draco might be scared that if he steps out of line, Lucius could use his power against him, or even put him in danger. Also, Lucius' cold and often unforgiving demeanor could make Draco feel constantly on edge in a fanfiction.
In some fanfictions, the power dynamics might be shifted. Maybe Lucius has become more powerful and is on the verge of destroying the wizarding world as Harry knows it. Harry, seeing no other way to stop him, decides to kill Lucius. It could also be a way for the writer to explore the darker side of Harry's character, showing what he could become when pushed to his limits and faced with an unrelenting enemy like Lucius.
I'm not sure if there is such a fanfiction. Fanfiction can cover a vast range of wild and creative ideas, but this particular concept seems rather unusual and might not be a common one. It could potentially exist in some niche corners of the fanfiction world, but I haven't come across it personally.
Perhaps there is a political reason. Some powerful pure - blood families might be trying to strengthen their influence by uniting the Potter and Malfoy families through this marriage, even if it's by force. Another possibility is that there is a prophecy that they misinterpreted which led them to force this marriage.
One reason could be to explore the power dynamics within the Malfoy family. Lucius is often seen as a powerful and strict figure, and this could be a way to show how far he might go in disciplining Draco. Another reason might be to add a dark and edgy element to the story, appealing to those who like more complex and disturbing plotlines.
One reason could be to analyze the psychological impact of an abusive family situation on a character like Draco. Writers may also be trying to break away from the typical view of the Malfoy family as just the 'bad guys' and dig deeper into the potential reasons for their behavior. Additionally, it might be a way to generate strong emotions and reactions from readers, as these types of stories can be very intense.
One reason could be to create drama. By having such a scandalous situation in the story, it can generate a lot of emotional turmoil among the characters and keep readers on the edge of their seats.
Maybe Lucius wants to use Harry for his own gain. Harry is a famous figure in the wizarding world, and Lucius could be thinking of leveraging Harry's status for something, like getting back into the good graces of the wizarding society after his fall from grace.
One possible reason could be the contrast between their characters. Lucius is from a traditional pure - blood family, while Hermione is a Muggle - born witch with great intelligence. The idea of these two very different characters interacting in fan - created scenarios might be fascinating to him.
