I really like 'The Dark Lord's Son: A New Path for Harry'. In this fanfic, Harry is raised by the Dark Lord's followers after Voldemort's victory. It shows a completely different Hogwarts, full of dark magic teachings. The story is full of twists and turns as Harry starts to question the world he's living in.
Obviously, the son of the Dark Lord would be a main character. He would be central to the story, with his actions and decisions driving the plot. Harry Potter himself might also be a key character. He could be a mentor figure to the son, guiding him away from the dark path. Hermione and Ron could also be involved, perhaps initially being suspicious of the son but later coming to understand him.
Well, one interesting plot could be the internal struggle of the son. He might be torn between the dark heritage from the Dark Lord and the good influence of Harry Potter's world. Maybe he has to hide his true identity while trying to figure out his own moral compass.
The concept of Harry as a Dark Lord in fanfiction is alluring because it subverts the original story. It allows fans to explore the 'what if' scenarios. What if Harry had given in to the power-hungry side? It gives a chance to rewrite the power structure in the wizarding world.
One interesting prank could be to magically change the Dark Lord's robes into something ridiculous like a frilly pink dress. It would be a shock to his dignity and his followers' perception of him.
Well, first, Harry would need to study the ways of the Sith. He has to understand his enemy. Then, he could combine his wizarding skills with some new knowledge. For example, he might learn how to use his magic to counter the Sith's mind - control abilities. He could also use his Patronus, which represents hope and light, to drive away the darkness of the Sith. And of course, he'd need to find the Sith's weakness, like in the way he found Voldemort's Horcruxes.
One possible take on a 'Dark Lord Harry Potter' fanfiction could be a story where Harry, instead of following the path of a hero, is influenced by dark forces early on. Maybe he discovers a hidden, dark side of magic that the Hogwarts faculty has been suppressing. This could lead to a completely different power dynamic within the wizarding world.
In many 'Harry Potter' fanfictions about 'Dark Lord Rising', it often explores the resurgence of Voldemort in new and creative ways. It might show different scenarios of how he regains power, like through dark magic artifacts that were not fully explored in the original books.
It might not be as mainstream as some other genres. Most fans prefer to see Harry as a hero rather than a Dark Lord supporter. However, in the vast world of fanfiction, there are always niche ideas, and this could appeal to a small subset of fans who like exploring darker and more subversive storylines.
The idea of Harry being the son of the Dark Lord is a huge deviation from the original story, which makes it very exciting. It allows for new character dynamics and plot developments. For example, how would the wizarding world react if they knew? And how would Harry deal with his new identity?
