What are some potential plot ideas in a fanfiction where Harry Potter is Voldemort's grandson?

Yes, the world of fanfiction is vast and full of strange and wonderful ideas. There might be some fanfiction out there where Harry Potter is Voldemort's grandson. Fanfiction writers often like to play with the established relationships in the original work and come up with really unique concepts. They might rewrite the story from this new perspective, changing many of the events and character interactions in the process. But to actually find such a fanfiction, one would probably need to search through various fanfiction websites.

One possible plot point could be the discovery of this relationship. Maybe Harry finds some hidden magical artifact or document that reveals the truth. Another could be the reaction of the wizarding world. Would they still see Harry as a hero or would they be suspicious of him? Also, Voldemort's reaction if he were to find out before his death could be interesting. He might try to use Harry for his own ends in a different way than in the original story.

It would be extremely different from the original story. The relationship between Harry and Voldemort would be completely redefined. Instead of pure hatred, there could be a sense of family - related conflict. Harry might struggle with the fact that he is related to the most evil wizard.

One challenge could be acceptance. The wizarding world might be very suspicious of his newfound heritage. They could fear that his demon blood makes him unpredictable or dangerous.

Sure, in the vast world of fanfiction, all sorts of crazy ideas are explored. This concept of Harry being Voldemort's grandson would be a really out - there plot. It could lead to stories where Harry has to grapple with this new identity, and how it affects his relationships with his friends like Ron and Hermione. Maybe it would also explore the implications for the fight against Voldemort, as now Harry has this strange family connection to his archenemy.

A potential plot twist could be that Harry actually has a hidden agenda. He accepts Voldemort's offer just to get closer and find a way to defeat him from the inside. He might pretend to be on Voldemort's side while secretly working against him.

One idea could be a fanfiction where Voldemort has a change of heart due to some ancient magic. Maybe he discovers a spell that shows him the true consequences of his actions and decides to work with Harry to fix the wizarding world instead of destroying it.

One idea could be that Harry, influenced by dark magic, forms an uneasy alliance with Voldemort. They could team up to take over the wizarding world in a different way than Voldemort originally planned, perhaps by ruling jointly. Another plot could involve Harry exploring the darker aspects of his own magic and using some of Voldemort's knowledge to do so, which causes a rift between him and his friends.

One idea could be a fanfiction where Voldemort gets a second chance at life but without his dark magic powers. He has to learn to live as a normal wizard in the wizarding world and Harry Potter has to decide whether to trust him or not.

One problem is that it may distort the characters. Harry Potter and Voldemort have very defined characters in the original series. A 'lemon' fanfiction may change their personalities in inappropriate ways just to fit the adult - themed plot. Another issue is that it can make the fandom seem less family - friendly. The Harry Potter fandom has a lot of young fans, and this type of fanfiction can be off - putting to them.
