What are some interesting plotlines in 'Harry Fights Voldemort' fanfiction?

One possible plotline could be that the children possess unique magical abilities due to their mixed heritage. For example, they might have the power to control both light and dark magic in a balanced way. Another could be that they are caught in the middle of the two worlds, with the wizarding community being suspicious of them because of their Voldemort connection, while Voldemort's remaining followers might try to use them for their own dark purposes.

Well, in some fanfictions, when Harry surrenders to Voldemort, it leads to a strange alliance. Voldemort, being overconfident, might keep Harry alive thinking he can use him. Harry could then start to learn more about the dark side from within, and perhaps find a way to turn some of Voldemort's followers against him. Also, it could be that the act of surrender causes a shift in the magical balance in the wizarding world. Some ancient prophecies might be set in motion that no one expected, and Harry has to figure out how to use this new situation to his advantage.

One possible plotline could be that Voldemort discovers a prophecy that Harry holds the key to some ultimate power that he desires, not just for domination but for something more profound, like the ability to reshape the wizarding world in a way he originally never considered. So he starts to protect Harry instead of trying to kill him immediately.

One possible plotline could be Harry using his newly discovered magical abilities in unexpected ways against the Dursleys. For example, he might make the Dursleys' dinner plates fly around when they are being particularly mean to him.

One possible plotline could be Harry struggling to regain control of his mind while Voldemort tries to use his body to carry out evil deeds. For example, Harry might have to fight against Voldemort's commands internally. Another could be how his friends notice the strange behavior and try to figure out what's wrong and save him.

One interesting plotline could be Harry using his new - found dominance to force Voldemort to face the consequences of his actions. He could make Voldemort see the pain he has caused to so many. Another could be that in a world where Voldemort is submissive, Harry tries to reform him, teaching him about love and friendship which Voldemort has long scorned.

One possible plotline could be that Harry discovers some long - hidden connection between himself and Voldemort that makes him like a 'prince' in Voldemort's dark world. Maybe it has something to do with a prophecy or a long - forgotten magic.

One interesting plotline could be an alternate universe where Harry and Voldemort have to team up against a greater evil. This flips the traditional dynamic on its head.

One interesting plotline could be exploring Voldemort's family history before he became the Dark Lord. Maybe there are secrets about his parents that were hidden. For example, in some fanfictions, they might delve into how his mother's family had some sort of ancient magic that was passed down but misused by Voldemort. Another could be about Voldemort having a long - lost relative who tries to stop him. This relative might have been hidden away all this time and has now emerged with unique powers to oppose Voldemort's tyranny.

In such fanfiction, a common plotline is that Harry's decision to join Voldemort creates a power shift. He might use his status as the 'Boy Who Lived' to undermine Dumbledore's reputation further. Since many in the wizarding world had put their faith in Harry, his joining Voldemort could lead to widespread panic and confusion. Harry could also start to recruit other disillusioned wizards to Voldemort's cause, using his own charm and the false narrative that Voldemort is actually a liberator of the wizarding world from the old, restrictive ways.
