Yes, there are likely some fanfictions out there with this concept. The idea of Merlin reincarnating as Harry Potter combines two very popular magical universes. It allows for a lot of interesting plot twists and character development. Writers might explore how Merlin's ancient magic and knowledge would manifest in the modern world of Harry Potter, and how it could change the course of the story we know.
Obviously, Harry Potter himself. And there could be Dumbledore, who might guide Harry in this new path related to Merlin. Also, Hermione and Ron could be there, either helping Harry or being a bit skeptical about this new adventure.
Yes, in a sense. There are some elements in 'Harry Potter' that can be seen as having similarities to the concept of Merlin. For example, both deal with magic and the idea of a special destiny for the main characters. However, 'Harry Potter' is also a very unique and complex world of its own with its own set of rules, characters, and storylines that go far beyond just being a simple fanfiction of Merlin.
Merlin in Harry Potter fanfiction can have various roles. He could be a mentor figure who exists in a sort of magical afterlife and imparts wisdom to the modern - day wizards like Harry. He might also be part of some long - forgotten prophecy or magical lineage that ties into the main plot of the fan - made story. For example, he could be the key to unlocking a new and powerful form of magic that the characters need to defeat a new dark force.
It's hard to say without reading it, but it could be the main characters from the Harry Potter series like Harry, Hermione, and Ron. They might be the ones exploring Merlin's legacy.
Merlin would be the central figure. Ron Weasley could play an important role too. He might be a bit skeptical of Merlin at first but then come to respect him. Dumbledore could also be a major character, having some sort of connection or prior knowledge about Merlin's return.
Another interesting pairing could be with Dumbledore. Fem Merlin could offer a different perspective on magic to Dumbledore, and they could work together to protect Hogwarts and the wizarding world. Their combined wisdom and magic could be a formidable force against any dark forces in the fanfiction.
Often, there are other characters from the original Harry Potter series as well. For example, some fanfictions might include Hermione as a friend or mentor to the descendant. She can use her intelligence to help the main character understand their powers better. And of course, there could be some original characters created specifically for the fanfiction, like a mysterious wizard who also has a connection to Merlin's past.
In Harry Potter Merlin fanfiction, a key characteristic is the exploration of different magical cultures. The formal magic education in Harry Potter's world contrasts with the more instinctual magic in Merlin's world. This can lead to some great storylines where characters learn from each other. For example, Ron could be taught by Merlin how to sense magic without a wand. Moreover, the fanfictions often play with the timelines. Since Merlin is set in a more ancient time, stories might involve time - travel or the influence of ancient magic on the modern wizarding world of Harry Potter.
Popularity of Merlin as Harry Potter fanfiction is a bit of a mixed bag. On some fanfiction websites, there are a decent number of stories that fall into this category. But in the grand scheme of things, it doesn't have the same level of popularity as, say, a typical Harry Potter fanfiction that stays true to the original series' characters and settings. It attracts those who are interested in exploring the crossovers between two magical universes, but it's not as widespread as other forms of Harry Potter - related fan works. There are probably fewer authors writing this type of fanfiction compared to more common Harry Potter fanfiction themes.
