There could also be an original character created specifically for this fanfiction. This character could be a dragon trainer from a far - off land who comes to Hogwarts to help with the situation regarding the dragon. They might have unique abilities and knowledge about dragons that the regular Hogwarts students and teachers lack.
Hermione might also be a main character. With her vast knowledge of magic, she could be the one researching about the dragon, its habits, and how to deal with it. Maybe she discovers an ancient spell that can communicate with the dragon.
Maybe Neville could be involved too. He has shown great courage in the original series. In this fanfic, he could be the one who has some prior knowledge about the dragon due to his family's history in the wizarding world. His knowledge could be crucial in helping Harry enter the dragon's territory and deal with whatever lies within.
Obviously, Harry Potter is one of the main characters. Since it's a fanfiction about him as a dragon or related to dragons, he would be central. And I think Hagrid would also be an important character as he has a great love for magical creatures, especially dragons. He could be the one to help Harry understand his new relationship with dragons.
Often, the main characters can include the well - known Harry Potter characters like Harry himself. He might get involved with dragons in some way, perhaps during one of his adventures outside of Hogwarts. Another common main character could be a new, original character created specifically for the fanfiction. This character could be a dragon trainer or a researcher of magical creatures, with a special interest in dragons.
It could be an original character created by the fanfiction writer. Maybe a young wizard who stumbles upon the dragon ritual by accident and becomes the central figure in the story.
Obviously, Harry Potter would be one of the main characters. And the Dragon King, of course. There might also be Harry's friends like Hermione and Ron who could get involved in the story related to the Dragon King.
The main character is most likely Harry Potter as he is the focus of the transformation into a metal dragon. However, depending on the direction of the fanfiction, there could be new characters introduced. For example, a wizard or witch who has knowledge about metal - based magic or dragons could play a significant role. But the core characters from the Potter series, such as Dumbledore or Snape, may also be involved in different ways, perhaps trying to guide Harry in his new state or dealing with the implications of his transformation on the wizarding world.
Well, Harry Potter would surely be one of the main characters. And of course, the dragon mage. There might also be characters like Hermione and Ron who could interact with the dragon mage in different ways, like Hermione being interested in the mage's dragon - related knowledge.
In addition, there could be some dragon characters. Maybe an old and wise dragon that Harry meets in his travels. This dragon could teach Harry about his dragon heritage, how to use his dragon powers properly, and give him advice on how to keep his disguise intact in the wizarding world.
The main character is obviously the Lightning Dragon Slayer. But there could also be appearances from well - known Harry Potter characters like Harry, Hermione, and Ron. They might interact with the slayer in various ways, either as allies or with some initial suspicion.
In addition to the well - known Harry Potter characters, there might be new characters created specifically for this fanfiction. Maybe there's a wizard or witch who has a deep understanding of the Black Dragon Emperor's origin and is trying to either control it or help it. There could also be some sort of antagonist who wants to use the Black Dragon Emperor's power for their own evil purposes, like a power - hungry Death Eater or a rogue wizard.
