In some 'Death Ace' Harry Potter fanfictions, 'Death Ace' might be a new villain. This character could be creating chaos in the wizarding world in a different way than Voldemort did. For example, instead of focusing on pure - blood supremacy, they might be after a powerful magical artifact that could change the balance of power in the wizarding world. Their actions would then force Harry and his friends to face new challenges and use different strategies to stop them.
A common plot in such fanfictions is the idea that death has a plan for Harry that goes beyond what Dumbledore or anyone else expected. It could be that death wants to use Harry to balance the magical world in a different way. So, Harry might be led to discover ancient magic that is related to life and death, and he has to decide how to use it. This could involve making alliances with creatures that are associated with death, like thestrals or dementors in a different context.
I'm not sure of a specific 'Death Ace' Harry Potter fanfiction off the top of my head. But you can try searching on popular fanfiction websites like FanFiction.net or Archive of Our Own. Use the keywords 'Death Ace' and 'Harry Potter' in the search bar, and you'll likely find some interesting stories.
One interesting concept could be how Harry Potter's control over death might change the entire wizarding world's view on mortality. It could lead to a new era where people no longer fear death as much. For example, if he can control who dies and when, it might disrupt the natural order that has been in place for centuries in the wizarding world.
One interesting plotline could be a deeper exploration of the Hallows' true powers. Maybe the characters discover new ways to use the Elder Wand, Resurrection Stone, and Invisibility Cloak that J.K. Rowling didn't fully explore in the original series. Another could be a different take on the final battle against Voldemort, with the Hallows playing a more complex role.
One possible plotline could be that Harry discovers a way to communicate with Death as an entity. Maybe he stumbles upon an ancient magic that allows him to have conversations with Death. Through these interactions, he gains a deeper understanding of life and death, and this new knowledge helps him in his battles against Voldemort. For example, Death could give him insights into the Horcruxes and how to destroy them more effectively.
Well, in some 'Harry Potter after death fanfiction', there might be the concept of unfinished business. For example, a character who died before they could complete a certain task or mission might be given a chance to do so in the afterlife. Or perhaps the idea of a spiritual journey where the dead characters have to atone for their past mistakes. It could also be about the dead communicating with the living through dreams or special magical objects, which can add a whole new layer of mystery and connection to the story.
One interesting concept could be a fanfic where the Death Curse is reversed. Instead of causing death, it gives life in a strange way. Maybe it brings back characters who were killed by other means, but with some unforeseen consequences.
One interesting concept could be how the 'Son of Death' status affects Harry's relationships. For example, it might make his friends view him differently, with some being in awe and others being a bit afraid.
One interesting aspect could be the exploration of Harry's complex relationship with death. In the original series, he has faced death many times, so in the fanfiction, it might delve deeper into his acceptance or even attraction to the concept of death. It could also be a metaphorical exploration, like death representing the end of his old self and the birth of a new, more powerful one.
In the fanfiction, it could be that Harry's friendship with Death is a secret known only to a few. He has to hide it from most of the wizarding world because they would not understand. This secrecy could add a lot of tension to the story. For instance, when strange things start to happen around Harry, like people seeing shadowy figures or experiencing unexplained chills, some might suspect dark magic. But in reality, it's just a side - effect of his connection with Death. Harry would have to struggle to keep his friendship a secret while also using the knowledge he gains from Death to protect his friends and the wizarding world.
