Harry Potter can be an interesting character to pair with them. It creates a lot of conflict and potential for character development. Given their opposing stances in the original story, it can lead to some really intense and thought - provoking scenarios in fanfiction.
Lucius may become more conflicted. He starts off as a loyal Death Eater, but having Harry in his care makes him question his loyalty to Voldemort. He might start to see the humanity in Harry and that could soften his cold - hearted nature. For example, he may find himself protecting Harry from other Death Eaters.
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.
In such fanfictions, Lucius might show his protection by shielding Draco from the Dark Lord's direct orders. For example, he could try to find ways to delay or modify tasks assigned to Draco that are too dangerous. He may also use his influence within the Death Eater ranks to keep Draco out of harm's way.
Snape and Lucius can be presented in various ways in fanfiction. One common portrayal is that Lucius, being from a wealthy and influential pure - blood family, may look down on Snape at first due to Snape's half - blood status. But as they grow older, they find common ground in their service to Voldemort (although Snape has his own hidden motives). Their relationship might be full of intrigue and hidden agendas.
He might be shocked at first. Since Lucius is a complex character, he could initially see it as a weakness in Harry that he could potentially use to his advantage in the wizarding world's power games.
For Lucius, his development could be a slow process. At first, he resents being around Hermione, but as he witnesses her magic and her kind heart, he starts to question his own values. He may begin to see the error of his ways regarding blood purity. Hermione might develop more patience. Dealing with Lucius, who has such different views, makes her learn to tolerate and try to change someone rather than just oppose them.
They could start by having an honest conversation. Lucius needs to admit his wrongdoings and Draco needs to express his pain. It's a first step towards redemption.
Hermione could be a great addition. She could be the voice of reason when Harry starts getting closer to Lucius. Her intelligence and knowledge of magic could also help in any situation they face together. Another good character would be Draco. Since Lucius is his father, it would add an interesting dynamic. Draco could be conflicted about his father's new relationship with Harry. And of course, Dumbledore. His wisdom and guidance could play a crucial role in how the relationship between Harry and Lucius develops.
