Well, Harry Potter's heritage in trial fanfic can play a big role. His family heritage, like being related to the Potters and the Blacks, might come into play. If his family has a certain reputation, it could either help or harm his case in the trial. Maybe his connection to powerful wizarding families makes people suspect he has certain motives or abilities that are relevant to what he's being tried for.
In trial fanfic, Harry Potter's heritage has a profound effect on the plot. His heritage as a half - blood, for example, could stir up different reactions among pure - blood supremacists in the trial. This could lead to more conflict and twists in the plot. His family heritage might also bring up secrets that were previously unknown, which could either clear his name or make him seem more guilty. Additionally, his heritage could determine who supports him during the trial and who tries to undermine him, thus shaping the overall flow of the story.
Sirius Black could also be part of it. He was Harry's godfather. He might have escaped from Azkaban earlier in this fanfic. He teams up with the Potters to rescue Harry. He could be the one who scouts out the Dursleys' house before the actual rescue operation, using his skills as an Animagus to stay hidden.
Another possibility is that Harry could find a hidden diary of his parents. The diary could contain their thoughts, experiences at Hogwarts, and even some secrets about the wizarding world that they were involved in. It would give Harry a more personal connection to his parents and their lives before him.
I'm not sure if the Potters (as in the characters in the Harry Potter series) would give away Harry Potter fanfic. In the official lore, there's no indication of them doing so. Fanfic is more of a creation by fans in the real world rather than something the fictional characters would be involved with.
Well, it could be a story where Harry stumbles upon the second branch of the Potters. Maybe it's a long - lost part of the family that has some unique magical abilities or secrets. Since it's a fanfic, the author might take creative liberties and introduce some interesting plot twists, like the second branch being involved in a hidden magical society or having a connection to an ancient prophecy that Harry then gets drawn into.
Harry could find a collection of letters. These letters might be from his parents to their friends or family members. Through these letters, he could learn about their relationships, their hopes and dreams, and get a better understanding of who they were as people. For instance, letters to Sirius or Remus could reveal a lot about their friendship and the plans they had for the future.
There's no real reason for the Potters to give away fanfic. Fanfic is a fan - created content, and the Potters are fictional characters. They don't exist in the real world where fanfic is created and shared.
It could also be that the Potters are under some sort of magical influence or curse. In the fan fiction world, there could be a dark force at play that makes them see the twins as more important. This force might be manipulating their emotions and perception, leading to the neglect of Harry.
Harry Potter is a given as the main character. In terms of the second branch of the Potters, it could include a variety of characters. There might be a Potter who has been living outside of the main wizarding society and has developed some unique magical skills. There could also be a group of Potters, like siblings or cousins from the second branch. One of them might be a bit of a rebel and another a more traditional Potter. These characters would interact with Harry, and their different personalities and abilities would drive the story forward.
