Perhaps a plotline could revolve around an old enemy of Grindelwald who resurfaces thinking Harry is a threat or an opportunity. This enemy might try to either corrupt Harry or use him as a pawn in their plans. Harry would then have to fight against this new threat while also dealing with his complex feelings about his grandfather. He could also discover some of Grindelwald's hidden knowledge or powers that were passed down to him, but use them for good instead of evil.
A plotline might involve the magical community's reaction. Since Grindelwald was a feared dark wizard, when the news spreads that Harry is his grandson, there could be a lot of chaos. Some might fear that Harry has inherited Grindelwald's dark tendencies. However, Harry could use this situation to prove that one's upbringing and choices matter more than blood relation. He could embark on a journey to clear the name of the Potter family and show that he is different from his grandfather.
One plotline could be Harry's discovery of his relation to Grindelwald. Maybe he finds an old family heirloom or a hidden letter that reveals the truth. Another could be how the wizarding community reacts to this news. Some might fear Harry, thinking he has inherited Grindelwald's dark tendencies.
Yes, there are some fanfictions exploring this concept. It's a very interesting and out - of - the - box idea that allows for new storylines and character dynamics to be created.
A fanfiction like this would be extremely complex. Firstly, it would have to re - write a significant part of Harry's backstory. His family's connection to Grindelwald would mean that there are secrets that have been hidden for years. There would be a lot of tension in the story. Harry might face ostracism from some in the wizarding community. On the other hand, he could also find new allies who believe that he is not defined by his relation to Grindelwald. The story could explore how magic can be influenced by family ties, and whether Harry has some latent powers or abilities related to Grindelwald. It could also delve into the political implications in the wizarding world, as Grindelwald was a major figure in the dark side of magic history.
Another angle could be his relationships with other characters. He could form an unlikely friendship with a descendant of those who fought against Grindelwald. This friendship would be full of tension at first, as they both come from opposing backgrounds. But over time, they learn from each other and grow together, showing that one's family history doesn't have to define them.
One possible plotline could be Harry's internal struggle with his heritage. Since Grindelwald was a dark wizard, Harry might battle with the idea of having such a connection. He could face prejudice from the wizarding world while also trying to understand if there are any redeeming qualities in Grindelwald's ideology that might be passed on to him.
In some fanfictions, there could be a plotline where Harry Potter discovers a hidden connection between himself and Grindelwald. Maybe through some ancient magic or a family secret. This connection then leads to a series of events where they must interact and understand each other better. For example, they might have to exchange magical knowledge to solve a mystery that is plaguing the wizarding community. Or perhaps Harry has to enter Grindelwald's mind to find a way to defeat a common enemy, which is a very mind - bending and exciting plot.
One possible plotline could be Harry initially being forced into the training but then gradually getting intrigued by Grindelwald's knowledge. He might start to question the traditional teachings of Hogwarts. Another could be that Harry is tricked into the training, thinking Grindelwald has good intentions only to discover the truth later.
One possible plotline could be that Harry is wrongly accused and sent to Azkaban. While there, the Dementors constantly torture him with their presence, draining his happiness and hope. Another could be that a dark wizard within Azkaban has a vendetta against Harry and uses dark magic to physically and mentally torture him. Or perhaps the prison system itself, with its harsh conditions and lack of proper care, is a form of torture for Harry, and he has to find a way to endure and escape while dealing with the psychological trauma.
One possible plotline could be that Harry uses his magic in self - defense and this leads to a whole new set of challenges as he tries to hide it from the wizarding world while dealing with Vernon's continued abuse. Another could be that the Dursleys finally get caught by the wizarding authorities for their mistreatment of Harry, especially Vernon's torture.
Perhaps Harry is held captive in a hidden location by Voldemort. While being tortured, he has visions of his past and the sacrifices his parents made. This gives him the strength to resist Voldemort's attempts to break his will. His friends then embark on a dangerous quest to find him based on these visions Harry manages to send out magically.
