Well, it could be that in this fanfiction, after the final battle, Harry is left with a sense of emptiness. He has lost many friends and has seen so much destruction. So, he starts to view death as an old friend. Death might appear to him in different forms, sometimes as a shadowy figure, other times as a familiar face from his past who has passed away. And they start to have deep conversations about the cycle of life and death, and how Harry's own life fits into this grand scheme.
One possible plot could be that Harry, having faced so many near - death experiences throughout his life, has developed a unique perspective on death. He might see it as a release from the burdens he has carried, like the weight of being the Chosen One. In this fanfiction, perhaps he has a series of dreams or visions where he converses with Death as if it were an old acquaintance, discussing the meaning of life, his past losses, and the fates of those he loves.
Well, I think Ginny could be a main character. As Harry's love interest, she would be deeply worried about Harry's strange connection with death. She might try to pull him back from this dangerous relationship. And then there could be Voldemort. Even though he is dead, his influence on Harry's life was huge. In this fanfiction, his shadow or essence could still linger, and Harry could discuss with Death how Voldemort's actions and his own role in defeating him have shaped his view of death.
One possible plot could be that a beloved hero character, perhaps someone inspired by the original Harry Potter series, sacrifices themselves to save the wizarding world from a new and powerful dark force. This selfless act would be in line with the themes of heroism in the original series.
Well, perhaps in this fanfiction, there's a big misunderstanding. Harry might think that by infiltrating the Death Eaters as one of them, he can actually bring them down from the inside. So he pretends to join them, but things get out of hand as he has to constantly prove his loyalty to the dark side, which is really difficult for him.
One possible plot twist could be that the daughter of death is initially thought to be on the side of evil but is actually a key to saving the wizarding world. Another could be that she has a secret connection to a major character from the original series that changes everything. Maybe she's related to Dumbledore in some way.
One consequence could be a distortion of the characters' original identities. Harry is a symbol of good, and a Death Eater is a symbol of evil. This pairing would muddle the clear - cut moral lines in the original story. Another consequence might be that it offends fans who love the original series for its values. It could also give a wrong impression to new readers or fans of the fanfiction, leading them to misunderstand the essence of the Harry Potter universe.
In a 'Harry kills all Death Eaters' fanfiction, the plot could start with Harry getting fed up with the constant threat the Death Eaters pose. He could go on a solo mission to hunt them down one by one. Along the way, he might face some moral dilemmas as he realizes that some Death Eaters might have families or could potentially be redeemed. But in the end, he decides that the only way to ensure peace is to eliminate them all. This could lead to a series of intense battles in different wizarding locations, and Harry could gain new allies or use some unexpected magical artifacts to achieve his goal.
The fanfiction could be about how the Pokemon world has changed over time and Pikachu is left behind as an 'old - fashioned' Pokemon. It might face discrimination or neglect because of its age. The death of Pikachu could be a symbol of the end of an era in the Pokemon world. It could also explore how the younger generation of Pokemon and trainers view Pikachu's legacy.
A possible motive could be self - preservation. If they believe that Voldemort's downfall is inevitable and that by saving Harry, they can gain some form of leniency from the side that opposes Voldemort. They might think that Harry has enough influence to spare their lives if they help him.
It could be that there are unforeseen circumstances in the Triwizard tasks. For example, the magical creatures or the challenges are far more dangerous than expected. The Triwizard maze might be filled with deadly traps that are not properly controlled, and Harry could be caught in one of them, leading to his death.
Maybe the 'paying death' is a ruse. Death is actually an entity that wants to test Harry's worthiness to time travel. So, Harry is made to go through a series of trials where he thinks he's paying death but in reality, he's just proving his courage, intelligence and loyalty, which are the real keys to time travel in this fanfiction.
