I'm not sure specifically as there could be many different takes in this fanfiction. It might be about Harry Potter having some special power or connection to black fire, perhaps using it in battles against dark wizards or in solving mysteries within the wizarding world.
One main theme is power. The Black Fire is often depicted as a very powerful force, and the characters must grapple with how to control or use it. Another theme is family legacy. Since it's related to the Black family, it explores how the family's past actions and secrets are intertwined with the Black Fire. Also, there's the theme of good vs evil, as the Black Fire can be used for both noble and nefarious purposes.
Most likely Harry Potter would be a main character, as the title implies. There could also be his friends like Hermione and Ron. And perhaps some new characters that are specifically related to the concept of the black fire, like an old wizard who teaches Harry about it.
One popular 'Harry Potter Black Fire' fanfiction is 'The Black Fire's Ascent'. It delves into the story of a new magical power related to the Black family. Another is 'Black Fire and the Prophecy' which weaves an exciting plot around an ancient prophecy and the Black family's secrets. And 'Black Fire: A Hogwarts Tale' that focuses on how the Black Fire element affects the daily life at Hogwarts.
Well, it might be that the Goblet of Fire has been corrupted in the fanfiction. It could be causing chaos in the Triwizard Tournament, endangering the lives of the students more than it should. Harry, being the hero, takes it upon himself to destroy it to restore order. For example, if it starts spawning dangerous and unfair tasks that are clearly not part of the original tournament's design.
No, it's not that common. Most Harry Potter fanfictions tend to focus on relationships, new adventures, or alternative timelines. While there are creative interpretations, this 'fire form' concept is rather unique and not as frequently explored as other themes.
There could be. 'Harry Potter' has a huge fan base and they like to explore different concepts. Fire elementals could be added to the story in many ways, for example, as a new kind of magical creature or as a power that a character discovers. However, not all fanfictions are easy to find. You might need to search through different platforms dedicated to 'Harry Potter' fan works.
In fanfiction, the possibilities are endless. Harry Potter being a fire mage could be part of a unique take on the story. It could change his role in battles, his relationships with other characters, and the overall plot. For example, as a fire mage, he might have a special connection with certain magical creatures that are associated with fire, or he could develop new spells and techniques related to fire magic that are not in the original books.
Well, in such a fanfiction, Harry could have found a magical fire - producing object that gives him the ability to fight the dragon with fire. He might have to learn how to handle this new power quickly while in the heat of the battle. The dragon, on the other hand, would use its natural abilities like flying and breathing fire in return. It would be a battle of wits and power.
It could be a very creative and metaphorical concept within the fanfiction. Maybe it represents the urgency or the consuming nature of time in the context of the Harry Potter universe, like how time can 'burn' through opportunities or events in the story.
