One interesting aspect could be the exploration of Harry's character development in a completely different family dynamic. In such fanfictions, Harry might grow up with different values influenced by the Malfoy family's pure - blood ideology. For example, he could be more inclined towards Slytherin - like traits, yet still retain some of his inherent Gryffindor courage in a more subdued way.
It completely alters the family background. In the original, Harry was an orphan from the Potter family, but in this fanfiction, he's part of the Malfoy family. This changes his upbringing, values, and social status in the wizarding world.
Yes, there might be. The Harry Potter fandom is vast and full of all kinds of creative and often unexpected fanfictions. Some fanfic authors like to explore alternate family relationships and storylines. However, it might be a bit hard to find if it's a 'lost' fanfiction. You could try searching in some of the older and more niche Harry Potter fanfiction archives or forums where dedicated fans might have saved or remember such an unusual piece.
The Malfoys could save Harry in fanfiction because of a personal debt. Maybe Harry once unknowingly did something that benefited the Malfoys greatly. This could be as simple as preventing a disaster from befalling their family business or saving the life of a family member secretly. When the time comes, the Malfoys feel obliged to return the favor and save Harry from whatever danger he is in. Also, it could be part of a complex plot where the Malfoys are trying to redeem themselves, and saving Harry is a big step in that direction.
In Harry Potter fanfiction, the Malfoys are often portrayed in a more complex and sometimes positive light. Some fanfictions might explore Draco Malfoy's struggle between his family's beliefs and his own emerging sense of right and wrong. He could be shown as having a change of heart, perhaps influenced by his interactions with Harry and his friends. This gives a new dimension to his character that we don't fully see in the original books.
Harry Potter himself is obviously a common character. He would be the father, so he'd be involved in trying to find his son or dealing with the aftermath of his son being lost. Hermione and Ron are also likely to be there. Hermione might use her vast knowledge to try and figure out where the son has gone or what has happened to him. Ron could be there for support, and perhaps even join in any search parties or investigations.
In the world of Harry Potter fanfiction, it's highly possible. The fanfiction community often takes the established characters and storylines and twists them in unique ways. The relationship between Harry and Voldemort is already central to the original series, so imagining Harry as Voldemort's lost son is a way to expand on that relationship in a completely new and unexpected direction. It could lead to all sorts of interesting plot developments, such as how Harry would deal with this newfound identity, how the wizarding world would react, and what it would mean for the ongoing battle between good and evil.
It could also be a part of a plot by the Malfoys to gain influence. They know Harry is a well - known figure in the wizarding world. By calling him and interacting with him, they might hope to improve their public image or gain some political leverage within the wizarding community.
In fanfiction, their relationship can be complex. Sometimes they might be forced to work together against a common dark threat. For example, in some stories, a new dark wizard arises who is more powerful than Voldemort, and both Harry Potter and the Malfoys have to put aside their differences to stop this new evil. It could also involve a change in Draco Malfoy's character, where he starts to see Harry in a different light and they form an uneasy alliance.
In the 'Harry adopted by the Malfoys' fanfiction, one possibility is that Harry would receive a very different kind of magical education. The Malfoys might try to mold him into a Slytherin - like wizard, but Harry's own Gryffindor - like courage would constantly be at odds with that. Also, his relationship with Draco could be very complex, ranging from initial rivalry as they are brought up in the same household to a possible understanding and even friendship later on.
