Voldemort could also play an important role. Since Harry is now the dark prince, there could be a complex relationship between them. Voldemort might see Harry as a potential ally or a threat, and their interactions would surely be a major aspect of the fanfiction, along with how Harry navigates this new relationship with the most feared dark wizard.
Well, obviously the Dark Prince himself is a main character. He's likely to be a complex figure with his own motives and desires. Then there could be his friends or followers, who might be other dark wizards or witches that support his cause.
The main characters would include the Dark Prince himself. Then, we might see characters from the original series like Neville Longbottom having a more prominent role in this fanfic. Maybe he becomes one of the key resistance fighters against the Dark Prince. And there could be some new characters introduced, like a mysterious wizard from a far - off land who has some knowledge about the Dark Prince's true nature and comes to Hogwarts to help in the fight against him.
It's hard to say for sure if it's a popular fanfiction without looking at specific data on its readership and reviews. However, the concept is quite interesting. In the original books, Harry is the hero, but this fanfiction flips the script. It could be popular because it gives readers a chance to see what might happen if Harry had taken a different path. It could explore themes of power, corruption, and redemption in a whole new light, which might appeal to a lot of Harry Potter fans who are looking for something fresh and thought - provoking.
Obviously, the Dark One is a main character. Harry Potter himself also often plays a crucial role as he is usually the one who has to face the Dark One in some way.
There could also be an original character created specifically for this fanfiction who becomes the Dark Phoenix. This character would then be a central focus, with their transformation and the resulting events driving the story forward. Their backstory, motives, and relationships with other characters would be important aspects of the narrative.
It's possible that the main character is the 'dark child' of course. There could also be a mentor - like figure, maybe an older wizard who tries to guide the child towards the light. And it wouldn't be surprising if there were some antagonists as well, such as other dark wizards who want to use the child's power for their own evil purposes.
Well, Harry Potter is most likely one of the main characters as it's a Harry Potter fanfiction. He would probably be at the center of the new revelations and story developments.
In this fanfiction, the main characters could be quite diverse. Since it's about a 'dark heir', there would likely be a character who embodies this role. It could be a previously unheard - of character with a complex backstory related to a dark legacy. Harry Potter might be involved to oppose this dark heir or to try and understand their motives. His friends, like Hermione and Ron, could also be part of the story. Additionally, there could be other magical beings or characters from the 'Harry Potter' lore, such as members of the Order of the Phoenix or Death Eaters, who are drawn into the plot due to the emergence of the dark heir.
Obviously, Harry Potter would be one of the main characters. And there would probably be some Atlantian characters like the King or Queen of Atlantis, or other important Atlantian figures. Maybe some of Harry's friends from Hogwarts could also be involved, like Hermione and Ron, if they also get dragged into the Atlantis adventure.
The main character would be Harry Potter as it's in the title. In addition to him, his friends from Hogwarts are likely to be involved. However, in a fanfiction, the author might introduce some original characters. For example, a snow - wizard who is an outcast but becomes Harry's ally in his adventures in the snow - filled magical realm. There could also be antagonists, perhaps a group of dark wizards who want to control the power of the snow and are opposed to Harry's new role as the 'prince of the snow'.
