What are some interesting 'Harry possessed by Voldemort' fanfictions?

There are fanfictions where Voldemort tries to possess Harry in a different way than in the original books. For example, instead of through a simple curse, he uses a complex magical artifact. This possession changes Harry's personality gradually, and his friends have to find a way to save him. In these fanfictions, the author often explores the psychological effects of possession on Harry, which is quite fascinating.

One idea could be that Harry starts having strange dreams where he sees through Voldemort's eyes. This could lead to him unknowingly helping Voldemort in some small ways at first, like revealing the location of some minor Order of the Phoenix safe houses. Another plot could involve the other characters slowly realizing something is wrong with Harry. For example, Hermione might notice that Harry is using some Dark Magic spells without hesitation, which is completely out of character for 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.

There could be a fanfiction where Voldemort saves Harry from another dark wizard. In this scenario, Voldemort has his own motives. He might want to be the one to defeat Harry himself in a more 'honorable' duel later, so he doesn't want some other dark force to take Harry out before he has his chance.

One interesting 'harry goes to voldemort' fanfiction could be where Harry tries to understand Voldemort's motives and in the process, discovers a long - lost magic that could potentially end the war. Another might be a story where Harry is magically transported to Voldemort's side during a battle and has to pretend to be on his side to survive and gather intelligence.

One interesting fanfiction could be 'The Dark Captivity'. In it, Harry is held in a magically fortified dungeon by Voldemort. Voldemort's motives for capturing Harry are explored in depth, not just about killing him but also about breaking his spirit. Another could be 'Captive Potter'. Here, Harry endures various mental tortures while being Voldemort's captive, but he manages to secretly communicate with his friends using a very unique and magical way.

One interesting 'Harry and Voldemort are soulmates' fanfiction could be the one where they discover their soulmate bond during a magical duel. The intense energy of the duel somehow triggers a connection that neither expected.

One possible fanfiction could be where Harry uses a powerful, ancient magic that he discovers in a hidden chamber at Hogwarts. This magic has the power to reverse death, but he doesn't fully understand the consequences. So, when he brings Voldemort back, Voldemort is initially weak and Harry tries to keep him in check while learning more about this new situation.

In some fanfictions, Harry's sister could be a time - traveler and accidentally end up in a time when Voldemort was still a student at Hogwarts. She then has to interact with him without revealing who she really is or the future she comes from. This creates a complex situation where she might see a different side of Voldemort and question whether he was always completely evil, all while trying to find a way back to her own time.

There are not many mainstream fanfictions with such a strange concept. However, some fan - made works might explore unique power dynamics or symbolic interpretations. Maybe you could search on some specialized fanfiction websites, but be prepared for very unorthodox and often creatively wild takes on the Harry Potter universe.
