Often, it might be that Harry has a series of encounters or quests that lead him to connect deeply with the concept of death and thus evolve into the avatar. This could involve facing deathly challenges, understanding the afterlife, or mastering forbidden spells related to death.
Harry Potter himself could be a potential Avatar of Death. Given his connection to Voldemort and all the death and sacrifice he has witnessed, he might develop some sort of connection to death in a more profound way. It would be a very dark and different take on his character, but it could also add a whole new layer of depth.
Another aspect could be the character development. If a character becomes an Avatar of Death, it would change their personality and motives completely. They might start seeing life and death in a very different way, perhaps even challenging the moral and ethical boundaries that are so important in the Harry Potter series. For instance, they could question the value of sacrificing oneself for the greater good when they have a new perspective on death.
Often, it could be that Harry stumbles upon ancient magical texts or has a mentor who introduces him to the art of wand making. Maybe he experiments with different materials and spells to create unique wands.
One common way is through inheritance. Just like in the original books, many fanfictions have characters inherit large fortunes from their families. For example, the pure - blood families like the Malfoys pass down their wealth from generation to generation.
One possibility could be that Harry uses his mastery of death to communicate with the spirits in the Avatar world, similar to how he could interact with the dead in the Potterverse. He might gain new powers related to the elements, as his connection to death gives him a deeper understanding of the balance in nature, which is crucial in the Avatar world.
Some fanfictions might depict their deaths very realistically, following the canon as closely as possible. This means showing Voldemort's arrival, his demand for Harry, and the unwavering love of Lily that led to her sacrifice.
Well, in this fanfiction, Harry might be a professor because of his extensive knowledge and experience in magic. He could be teaching younger students and sharing his wisdom.
Harry could be powerful in the fanfic because he's mastered advanced spells or has discovered unique magical artifacts that give him an edge.
In the fanfictions, Harry being a kid might involve his reliance on adults for support, his excitement over simple magical discoveries, and his efforts to fit in at Hogwarts while still having that childlike charm and vulnerability.
The story could develop in many ways. Harry might use his connection to death to access the spirit world in the Avatar universe more easily than others. This could lead to him discovering secrets about the origin of bending or the history of the Avatar. He could also use his Gryffindor courage to stand up against any form of oppression in the Avatar world. His skills in magic, combined with his new - found knowledge of the Avatar world, could make him a powerful force for good or, if misused, a great danger. As he interacts with the different nations and characters, he'd slowly change the dynamics of the Avatar world, all while dealing with his own identity as the master of death.
