It depends on various factors. Some fanfiction works gain popularity within specific fan communities. 'Harry Potter' has a huge fan base, but a 'Prince of Darkness' - themed fanfiction might be popular among those who like darker, more alternative takes on the story. However, it may not be as mainstream as some other more canon - compliant fanfics.
It could be an ancient and powerful dark wizard who has been dormant for a long time. Maybe someone from the time before Hogwarts was even founded.
In Harry Potter fanfiction, 'The Prince of Darkness' could refer to a number of things. It might be a new character created by the fanfiction writer, perhaps a dark wizard or a powerful, malevolent being. It could also be a title given to an existing character in a new, dark context, like Voldemort being given this title to emphasize his extreme evilness.
Perhaps it could be a corrupted version of one of the existing characters. For example, a character who has been influenced by dark magic and has turned into this 'prince of darkness'. It could be a Slytherin student who has delved too deep into the forbidden knowledge of the house and has become a dark force. Another possibility is that it's a long - lost relative of a major villain like Voldemort, carrying on his legacy in a new and terrifying way.
It could be a new villain that the fanfiction author has introduced. Maybe a long - lost relative of Voldemort who has emerged to continue his dark legacy.
Maybe it could be about a character, perhaps Harry himself, being corrupted and turning into a 'Prince of Darkness'. He could start using dark magic and turn against his friends and Hogwarts.
In some 'prince of darkness harry potter fanfiction', there might be a plotline where the 'Prince of Darkness' is a misunderstood figure. He may have been misjudged by the wizarding community for centuries. And now, through his interactions with Harry Potter, his true nature and motives start to be revealed. This could lead to a situation where Harry has to decide whether to trust him or not, and it could also cause a rift between Harry and his friends who might be more suspicious of the 'Prince of Darkness'.
I'm not sure specifically as there could be many different takes in a fanfic with that title. It might be about a character in the Harry Potter universe who is seen as the 'prince of darkness', perhaps a new villain or a dark interpretation of an existing character.
The 'darkness' in 'Harry Potter' fanfiction could refer to various things. It might be about the Dark Arts that are often explored in a more in - depth or alternative way in fanfiction. For example, some fanfictions might focus on the origin and true nature of dark spells like the Unforgivable Curses.
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.
No. Since adult fanfiction often contains inappropriate content, it is not promoted or widely popular. Moreover, 'Prince of Darkness' is a rather specific topic. Usually, fanfictions about more mainstream and positive characters or stories are more likely to be popular.
