Well, Danny Phantom is surely a main character in this fanfiction. He's the one who would be doing the 'fanning the flames' so to speak. His nemesis, like Vlad Masters, could also be a main character. Given that Danny's actions are fanning the flames, it could be in the context of a battle or rivalry with Vlad. Additionally, his family members like his parents and sister Jazz might be involved as they often play important roles in Danny's adventures.
In the 'danny phantom fanning the flames fanfiction', Danny Phantom is the central figure. However, depending on the plot, other ghost characters could be main characters too. For example, if the story is about a power struggle in the Ghost Zone and Danny is fanning the flames of that struggle, then powerful ghost lords or entities might be main characters. Also, any new characters that the author creates specifically for this fanfiction to interact with Danny and be part of the events where he is fanning the flames could be main characters as well.
I'm not sure specifically as there could be many different takes in a fanfiction with that title. It might be about Danny Phantom getting into some sort of situation where he is fanning the flames, perhaps literally in a battle with a fire - based enemy or metaphorically, like making a conflict or situation worse.
I don't know who the author of this fanfiction is. There are so many fanfiction writers out there and without more context or research, it's hard to determine.
The title 'fanning the flames dark danny fanfiction' is rather intriguing. 'Dark Danny' gives the impression of a Danny who is different from the original, more positive version. He could be influenced by evil forces or have his own inner demons. 'Fanning the flames' seems to suggest that there are elements in the story that are provoking or exacerbating this dark aspect of Danny. It might involve things like other characters' actions, certain events that occur, or even Danny's own choices that continuously make his dark side more intense. Maybe it's a story about how a small change in Danny's character starts to snowball into a much larger, darker transformation due to these fanning - the - flames factors.
Obviously, the main character would be Danny Phantom himself, but in two different forms or versions. One would be the original Danny Phantom from the canon source, and the other would be a version created by the fanfiction. There might also be his friends like Sam and Tucker who could play important roles in helping the two Dannys understand each other and deal with any issues that arise from their meeting.
In addition to the ghosts, there might be some human characters that are important in the 'phantom city danny phantom fanfiction'. They could be Danny's friends or family members who get involved in the events of the Phantom City. Their reactions to the supernatural world and their interactions with Danny and the ghosts would add an interesting dynamic to the story.
Obviously, Danny Phantom and Dan Phantom are the main characters. Danny is the original form, a heroic character, and Dan is his more evil and powerful transformation.
His friends like Sam and Tucker are likely to be main characters too. They usually support Danny in his adventures and add a human element to the story. Sam with her gothic style and strong will, and Tucker with his tech - savvy skills are important parts of Danny's world.
In many fanfictions, there could be new characters created specifically for the Renegades. These might be other half - ghosts or humans with special abilities that complement Danny's. For example, a character who can manipulate time in a small way to help the group in battles.
Jazz, Danny's sister, often plays an important role. She might use her psychological knowledge and her understanding of Danny to try to solve the mystery of his disappearance. And of course, some of Danny's ghostly foes might also be involved, as their actions could be related to his vanishing.
Well, clearly Danny Phantom is likely to be one of the main characters. And since it's about devils, there must be some devil characters as well. Maybe there's a lead devil character that Danny has to face off against.
