Well, it's very likely. Since fanfic writers are extremely creative. They often take the basic elements of the Harry Potter world and blend in all sorts of new concepts. A 'Crown Prince' concept could be used in a number of ways, perhaps as a new character in a story set in a wizarding kingdom that's related to the main Harry Potter story. So, searching for it on popular fanfic platforms should be your first step.
There's no easy way to tell who created it without more context. Fanfic is a vast and decentralized world. It could be a relatively unknown author who just had this creative idea for a Harry Potter - related fanfic. Maybe it was created by someone in a small fanfic community or on a particular fanfic platform.
In fanfic, authors often take existing characters and put them in new situations or give them new identities. 'Harry potter crown prince of fanfic' could be a title or concept for a fanfic where Harry Potter is seen as the pre - eminent or most important character in a new, fan - created world. This could involve a story where he has some sort of inherited or bestowed power and status that is equivalent to that of a crown prince, perhaps ruling over a magical realm within the fanfic's unique storyline.
It could be about Harry being a crown prince in a hidden wizarding kingdom. Maybe he discovers his true heritage and has to deal with the responsibilities that come with being royalty while still facing the threats from Voldemort.
There are fanfictions that blend the royal and magical worlds. In some, the Crown Prince might be a secret wizard all along. He could attend Hogwarts undercover, and his path could cross with Harry's. A great fanfiction might explore how their different upbringings - one in royalty and one in the wizarding world - shape their views and how they learn from each other. You can find such fanfictions on platforms like FanFiction.net or Archive of Our Own by simply searching for relevant tags like 'Crown Prince' and 'Harry Potter' combination.
A lot of Crown Prince Harry Potter fanfictions explore the theme of cultural exchange. The Crown Prince brings the traditions and values of his own royal culture into the wizarding world. This can lead to some interesting scenarios, like new magical practices being introduced, or different social norms being challenged. There are also fanfictions that focus on the Crown Prince being a catalyst for change in the wizarding world. Maybe he helps to modernize Hogwarts or reform some of the old - fashioned wizarding laws, all while interacting with Harry Potter and other key characters.
Maybe the prince is from a neighboring magical country. For example, he could be from a place like Beauxbatons or Durmstrang. He comes to Hogwarts on an exchange program of sorts and that's where he meets Harry and decides to court him. This would add an element of international magical relations to the fanfic.
A Diana Prince and Harry Potter love fanfic is quite an unusual concept. In such a fanfic, there would be many challenges in terms of bringing their two very different worlds together. Their different powers, cultures, and storylines would need to be carefully woven. However, if done well, it could be a very engaging read. For example, the idea of Diana being attracted to Harry's courage and his magic, and Harry being in awe of Diana's strength and beauty could be the basis for a romantic plot.
Yes, there might be. There are numerous fan - created works in the Harry Potter and Marvel (Asgard is from Marvel) crossover genre. You can try searching on fanfic platforms like Archive of Our Own or FanFiction.net.
The Crown Prince and the First Prince were not the same person. The Crown Prince was older than the Eldest Prince. The Crown Prince was conferred the title of Crown Prince the moment he was born and was not in the Prince Sequence. The First Prince's mother was not the Empress. Thus, it could be concluded that the Crown Prince was not the Crown Prince.
