It might also be to create new plot twists. For example, if Draco is not Narcissa's son, there could be a mystery around his true identity. Who are his real parents? This mystery can drive the plot forward and add an element of intrigue to the fanfiction.
Perhaps the author wants to break away from the traditional canon and create a more diverse and inclusive story. By making Draco not related to the Malfoys, the author can introduce different cultural or social backgrounds for him. For instance, he could be from a family that values kindness and equality over blood purity, which would completely change Draco's personality and how he interacts with other characters in the wizarding world.
He could potentially be the result of a mix - up at birth. Suppose a spell went wrong in St. Mungo's Hospital for Magical Maladies and Injuries. Draco could have been accidentally switched with another baby. In this scenario, his true family could be a completely different set of wizards, and his entire life trajectory, including his relationships with other characters like Harry Potter, would be vastly different.
One reason could be to create a shock factor. By making Naruto Madara's son, it completely flips the established relationships in the Naruto world, which can draw readers who are looking for something completely different. Another reason might be to explore new power dynamics. If Naruto were Madara's son, his potential powers and how they develop could be re - imagined in a very different way.
One common theme is family loyalty. Narcissa is always very protective of Draco in these fanfictions. Another theme is the struggle against the dark side. Given Draco's situation in the original story, many fanfictions explore how Narcissa helps him deal with the pressure of being on the wrong side. Also, the theme of redemption often comes up, especially in relation to Draco's actions during the wizarding war.
Fanfiction often involves taking existing fictional characters and creating new, non - canon scenarios. In the case of 'harry impregnates narcissa fanfiction', it's a very unorthodox and non - traditional scenario where the author has created a situation where Harry has impregnated Narcissa. This goes against the normal storylines of the original Harry Potter series and is more of a creative and often controversial exploration by fans.
The son could be highly adaptable. Growing up with two such different fathers, he would be exposed to different ways of thinking. He might have Draco's slyness when it comes to getting out of tricky situations, but also Harry's selfless nature when it comes to helping others. He could also be very good at magic as he would inherit the strong magical genes from both his fathers. And he would probably be a bit of an outcast at Hogwarts, not fully fitting into either the Slytherin or Gryffindor mold.
One reason is to explore deeper emotional bonds. It makes their relationship more complex and intense.
One interesting Draco and Narcissa fanfiction could be about Narcissa protecting Draco from the dark side's full influence. Maybe she secretly teaches him about the importance of love and kindness in a world full of dark magic. This could show a different side of their relationship, not just the typical pure - blood family bond.
One common theme is family loyalty. In many fanfictions, Narcissa will do anything to protect Draco, and Draco in turn respects and loves his mother deeply. For example, in stories where the Malfoy family is in danger, they stick together.
Well, I really liked 'A Mother's Love: Narcissa and Draco'. In this fanfiction, it shows Narcissa's unwavering support for Draco, especially when he's faced with the dangerous tasks assigned by Voldemort. It's a heart - warming read. Then there's 'The Malfoy Legacy: Mother and Son' which gives a detailed account of how Narcissa tries to preserve the Malfoy name and protect Draco at the same time. And 'Draco's Redemption through Narcissa' is also interesting as it shows how Narcissa plays a crucial role in Draco's journey towards redemption.
Some writers might be trying to create shock value. By coming up with such a disturbing concept as Naruto being dismembered, they can immediately grab the attention of readers, even if it's in a negative way.
