The main characters would surely include Harry Potter. He is the one making the trade with Death. Death is also a main character as it is the entity with which the trade is being made. Additionally, Dumbledore could potentially play a role, either as a guiding spirit from beyond (if he has passed away in the context of this fanfiction) or as someone whose teachings influence Harry's decision to make the trade.
Harry Potter is the key character in this fanfiction as the title implies he is the one trading with Death. Death is another main character. There could be other important characters too. For example, the Weasley family might be involved. Molly Weasley could be trying to protect Harry like a mother figure, while the other Weasley siblings might be caught up in the chaos that ensues from Harry's deal with Death. Also, Voldemort or his remnants could be part of the story, either as a threat that prompts Harry to make the trade or as an unexpected factor affected by the trade.
One interesting plot point could be how Harry negotiates with Death. Maybe he offers something unique like his knowledge of magic that exists beyond the normal wizarding world understanding. Another could be the consequences of such a trade on the wizarding world as a whole, for example, it might change the balance between good and evil magic.
Hermione could be a main character. She might be the one who first notices the strange changes in Harry after he becomes friends with Death. She could try to research about this unusual friendship in the library, using her vast knowledge to understand the implications. Ron could also be important. He might be initially skeptical about Harry's new 'friend' but then come to accept it as he sees the positive effects it has on Harry and the help it provides in their fight against dark forces.
Harry Potter would definitely be one of the main characters, since it's about him being the 'child of death'. There might also be his friends like Hermione and Ron, as they are often involved in his adventures.
Obviously, Harry Potter is the main character as it's about him being the Son of Death. Hermione and Ron are likely to still be important characters, as they are his closest friends.
In this fanfiction, Harry Potter is probably the central figure as it seems related to his new identity as the Heir of Death. However, other characters like Dumbledore could play significant roles. Dumbledore might be guiding Harry through this new discovery, or perhaps he's been hiding some secrets about the Heir of Death all along. Additionally, we may see characters from the dark side, like Voldemort or his followers, being involved in the story, either trying to stop the heir or use their power for evil.
The main character is Harry Potter. In this fanfiction, Death is not just an abstract concept but an important entity. It's likely that other characters like Ginny Weasley could also be involved. Ginny might be worried about Harry's new relationship with Death. And characters like Luna Lovegood could offer their unique perspectives on this strange occurrence, adding depth to the story.
Obviously, Harry Potter is one of the main characters. And Death, which is given a more prominent role in this fanfiction compared to the original books. There may also be other characters from the original series like Hermione and Ron who might play important roles in the story, perhaps helping Harry in his interactions with Death or being involved in the events that are related to the new plotlines involving Death.
Obviously, Harry Potter would be the main character since it's in his name. He is the one who befriends Death. Hermione Granger and Ron Weasley are also likely to be important characters. They are Harry's closest friends and would be involved in the story, either trying to understand Harry's new friendship with Death or being affected by it in some way. For example, they might be worried about Harry's sanity or the implications of befriending such an otherworldly being.
Obviously, Harry Potter himself is always a main character. He is the one most directly associated with the concept of death in the original series, what with his parents' death and his multiple near - death experiences.
Obviously, Harry Potter himself. He's the one who has become the Master of Death. Hermione and Ron would also be important. They'd be there to support Harry, and also to question his new power and the moral implications. Dumbledore might also play a role, perhaps as a guide from beyond the grave, since he was always so interested in the Deathly Hallows and what it means to be the Master of Death.
