Obviously, Harry Potter is one of the main characters. He is the one who is being helped by the Malfoys. Then there are the Malfoys themselves. Lucius Malfoy, with his knowledge of the dark wizarding world and connections among the Death Eaters, could play a crucial role. Draco Malfoy is also important as his relationship with Harry has always been complex and in this fanfic, it might be a key factor in his family's decision to help Harry.
Perhaps in the fanfic, the Malfoys help Harry because Draco has a change of heart after seeing the true brutality of Voldemort's regime. This could lead to the Malfoys providing Harry with a safe haven when he's on the run, which is a very interesting turn of events as they were once his enemies.
Definitely. A lot of fanfic authors like to take the concept of redemption and apply it to the Malfoys. In the 'The Malfoys help Harry and Hermione' fanfictions, it often shows a more complex side of the Malfoys. For example, Draco Malfoy might start to see the error of his ways after some personal experiences, and then convince his family to help Harry and Hermione. It's really interesting to see how the relationships between the characters develop in these stories.
One possible motive could be redemption. They may have realized how wrong they were in following Voldemort and want to make amends by helping the good side. For example, Draco might feel guilty for his past actions and decide to help Harry and Hermione to fight against the Dark Arts.
Harry could develop a more guarded personality. Since the Malfoys have a certain reputation, he may need to be careful about his actions and words. He might also become more calculating in his interactions, learning from the Malfoy family's political maneuvers.
Well, one possible plot development could be that the Malfoys, in rescuing Harry, have a change of heart towards the whole fight against Voldemort. Maybe they start to see the error of their ways and side with Harry more openly. For example, they could use their influence in the wizarding world to help Harry gather more allies.
I think Dobby could also be a significant character in this fanfic. Since he has connections to both the Malfoys and Harry. He might be the one who gives the Malfoys the idea to rescue Harry or helps in the rescue in some way. Also, Voldemort or his Death Eaters could be important in the background as the threat that Harry needs to be rescued from. Their presence would constantly loom over the story, making the Malfoys' actions more dangerous and significant.
One such fanfiction could be 'The Unexpected Alliance' where Draco surprises everyone by helping Harry in Diagon Alley and changing the perception of the Malfoy family.
His character might develop in a more self - interested way. Growing up with the Malfoys, he may not have the same selfless hero complex as in the original. He could be more focused on protecting his family (the Malfoys) and their status in the wizarding world.
One interesting plot point could be how Harry adapts to the Malfoy family's pure - blood traditions. He might struggle with their values at first. For example, the Malfoys' view on blood purity and how that contrasts with Harry's more inclusive nature.
