One idea could be that the character discovers a hidden Horcrux in a place no one expected, like in an old, abandoned wizarding prison. They have to face numerous dark magic traps alone. Another could be that they are being hunted themselves while on the Horcrux hunt, adding an extra layer of danger.
Neville could also be an excellent choice. He has shown great courage throughout the series. His knowledge of Herbology could come in handy when dealing with Horcruxes that might be hidden in or protected by plants. And his growth from a shy boy to a brave young man would make for an interesting arc in a solo Horcrux hunt story.
The Horcrux hunt with Harry, Fleur, and Tonks in fanfiction could be full of adventure. Harry has his own experience and determination. Fleur could add an element of mystery and allure. Tonks, with her unique magic, is quite a valuable asset. They could start by researching the possible locations of Horcruxes in old wizarding libraries. Fleur might be able to charm the librarians into giving them more access. Tonks could change her appearance to look like a different wizarding scholar. Harry would be constantly on the lookout for any signs related to Voldemort. Their journey would be filled with close calls and unexpected allies.
The main characters are obviously Harry and Daphne. Harry, being the Boy Who Lived, has a lot of experience with fighting Voldemort and is determined to destroy all the Horcruxes. Daphne, on the other hand, is likely a Slytherin or has some connection to Slytherin. She brings her own set of skills and knowledge to the Horcrux hunt. Maybe she has a good understanding of dark magic or some family secrets that can be useful.
One common theme is the growth of their relationship. As they hunt for Horcruxes together, their bond deepens whether it's a platonic friendship or something more in some interpretations.
Yes, in some fanfiction, Harry Potter is considered a Horcrux. This concept adds an interesting twist to the original story, exploring different aspects of magic and the connection between Harry and Voldemort.
One consequence could be that his connection to Voldemort becomes even stronger. This might lead to him being able to sense Voldemort's actions and thoughts more clearly, but also make him more vulnerable to Voldemort's attacks on his mind. Since the Horcrux is a part of Voldemort's soul, it could also start to influence Harry's personality, making him more aggressive or moody at times.
Well, a possible plotline is that they discover a Horcrux in a place that was previously thought to be just a mythical or lost location. Maybe it's hidden in an ancient wizarding ruin that has been long forgotten. As they search for this Horcrux, they encounter all kinds of magical creatures and traps. And also, their relationship might develop romantically during the hunt. They share moments of fear and triumph which bring them closer together.
There's also 'Horcrux Hunt: The Unseen Bond' which delves deep into the relationship between Harry and Hermione during their search. It has some really creative interpretations of how they overcome the obstacles related to the Horcruxes. In this fanfiction, they face not only the danger of the Horcruxes themselves but also the political unrest in the wizarding world at the same time. Their friendship is put to the test and grows stronger as they progress in their hunt.
If Harry were to create a Horcrux in fanfiction, it would likely lead to a great corruption of his soul. Horcruxes are dark magic, and the act goes against all that Harry stands for in the original series. He might start to show signs of increased aggression, a detachment from his friends, and a growing attraction to the Dark Arts.
