Hermione could be one of the characters in the harem. Her intelligence would be an asset to Harry, even as a Dark Lord. She might be torn between her loyalty to the original Harry she knew and her feelings for this new, darker version. Ginny could also be part of it. Given her connection to Harry in the original story, her presence in the harem could add an interesting dynamic, especially if she tries to change Harry back to his old self.
One interesting plot could be Harry Potter, as the Dark Lord, having to balance his newfound power with the relationships in his harem. Each character in the harem might have different motives and loyalties, creating internal power struggles within the group.
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.
Obviously, Harry Potter himself is a central character. Hermione Granger often appears as she has a strong connection to Harry in the original series. Ginny Weasley might also be part of the harem as she was Harry's love interest in the books. Additionally, some original characters created for the fanfiction might be included to add more variety to the harem.
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.
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.
I'm not sure if it's a particularly popular genre. There are so many different types of fanfiction in the Harry Potter world, and while some might be interested in stories involving Harry Potter and Lord Peverell in a harem - type situation, it might not be as mainstream as other themes like Harry's adventures at Hogwarts or his battles against Voldemort. It really depends on the niche interests within the large and diverse fanfiction community.
