Hermione is often one of the most intriguing. In these fanfictions, she might be the one trying to bring Harry back from the dark side. Her intelligence and loyalty are put to the test in a whole new way. Draco Malfoy can also be very interesting. He could be an ally or an enemy to 'Dark Lord' Harry. If he's an ally, it could be because he sees potential in Harry's new power structure. If an enemy, it might be out of his own sense of self - preservation or loyalty to his family's traditional views. And then there's Luna Lovegood. She might be the one character who still sees the good in Harry even when everyone else is afraid. Her unique perspective on the world can add a lot of depth to the story.
Sirius Black, even in death, can play an important role. His spirit or memories could haunt 'Dark Lord' Harry, reminding him of a different path. Or perhaps there could be some magical way he is brought back to life to try and save Harry from the dark side. Bellatrix Lestrange is another character to watch. She could be a mentor to 'Dark Lord' Harry, teaching him more about the Dark Arts. However, her own insanity and loyalty to Voldemort could also cause friction. And finally, Albus Dumbledore. His post -mortem influence on the wizarding world and how 'Dark Lord' Harry deals with his legacy can be a major part of the story.
Severus Snape's memories or a ghostly apparition of him could be a main character. Since he had such a complex relationship with the dark lord, he could offer insights to the daughter. Also, Ginny Weasley could be significant. She's a strong witch in her own right and could be a role model for the dark lord's daughter. And then there are the professors at Hogwarts like McGonagall who would have to deal with the situation of having the dark lord's daughter at school.
In many of these fanfictions, a common theme is redemption. Even though Harry is the 'Dark Lord', there can be a journey towards redemption. This could involve him realizing the error of his ways after causing chaos in the wizarding world. Another theme is the exploration of the Slytherin side of Harry. Since Slytherin is often associated with dark magic and ambition, it gives room for fanfiction writers to play with the idea of Harry embracing his Slytherin traits more fully. Love, in a twisted way, can also be a theme. Maybe Harry's new dark self still has feelings for Ginny, but they are expressed in a much darker and more complex manner.
One interesting plot could be Harry Potter using his intelligence to outwit the Dark Lord in a completely different way than in the original series. For example, instead of relying on pure magic power, he uses his knowledge of magical history and lore to find the Dark Lord's weaknesses. Another plot might involve the Dark Lord having a more complex and intelligent personality, making his actions less predictable and more thought - out. This could lead to a more cat - and - mouse - like battle between Harry and him, with both sides constantly strategizing.
Dumbledore might play an important role as well. He would be guiding Harry through this new and strange situation. He could have some secrets about the Lord of Azkaban that he reveals to Harry over time. Also, some of the Azkaban guards or prisoners could become significant characters as Harry tries to reshape Azkaban.
Harry Potter and Sirius Black are also paired quite often. Sirius was a very important figure in Harry's life. In slash fanfiction, with Harry being dark and powerful, their relationship can take on a different meaning. Sirius's wild and rebellious nature can be paired well with Harry's new - found power and darker side, creating a relationship that is full of passion and a sense of freedom.
Hermione Granger is very influential. She is extremely intelligent and well - read. She often helps Harry and Ron with her vast knowledge of magic, and her determination and loyalty contribute a great deal to their adventures and the fight against evil.
Fred and George Weasley are also favorites. Their mischievous nature can be amplified in fanfictions. They could create new and even more spectacular magical pranks specifically aimed at Umbridge, like turning her office into a never - ending maze of trick stairs and hidden rooms filled with various magical creatures that drive her crazy.
The trolls could play an important role. They are mysterious and have their own magic. In dark Elsa fanfiction, they might be the ones who try to either contain Elsa's dark powers or guide her towards using them in a more positive way. Also, a new character could be introduced, like a powerful sorcerer from a far - off land who is either drawn to Elsa's powers or sees her as a threat and wants to eliminate her.
In some WBWL fanfictions, Harry is ostracized by the wizarding world because they believe he's not the 'true' savior. This makes him turn dark. He might form an alliance with Voldemort's followers out of spite. The plots often explore how his personality changes. He could become more ruthless and calculating, using his natural magical talent in ways that are more self - serving rather than for the greater good.
Well, in terms of a Dark Souls - Harry Potter fanfiction, the idea of the Dark Souls' estus flask could be reimagined in the wizarding world. It could be a special potion that only certain wizards can brew, and it has limited uses. Also, the character classes in Dark Souls, like the knight or the mage, could be used to categorize the students at Hogwarts in a different way. For instance, the knight - like students could be part of a new dueling club that focuses on more physical and defensive magic.
