One idea could be that Merlin, with all his ancient magic knowledge, reincarnated as Harry Potter would be able to quickly master spells at Hogwarts. He might even introduce some long - lost magic that was known in his previous life. For example, he could have a unique way of handling potions that was based on his experiences in Camelot.
In a fanfiction, if Merlin was reincarnated as Harry Potter, his relationships would be very interesting. He might befriend Hermione and Ron in a different way. Given his past as Merlin, he could be more of a mentor figure to them, guiding them through the mysteries of magic using his age - old wisdom. He may also have a different perspective on Voldemort, seeing him as just another dark wizard like the ones he faced in Camelot.
One popular 'Fem Merlin Reincarnated as Harry Potter' fanfic is 'Merlin's Second Chance at Hogwarts'. It has an interesting plot where the female Merlin uses her old - world magic knowledge in the new setting of Hogwarts. Another one could be 'Fem Merlin's New Adventure in the Wizarding World' which focuses on her unique relationships with the Hogwarts professors.
In these fanfictions, a recurring theme is the adaptation. Fem Merlin has to adapt to the new rules, new culture, and new social environment of the Harry Potter universe. This includes things like the Hogwarts houses, the way magic is taught, and the political situation in the wizarding world. Another theme is the use of her past knowledge. She might use her knowledge of Camelot's magic to solve problems in Hogwarts or to fight against the dark forces. Also, the theme of self - discovery is present as she learns more about herself in this new reincarnated form.
Merlin, being a powerful magician, would quickly grasp the magical aspects of the Harry Potter fanfiction. He would be interested in the different types of magic, like transfiguration or potions. He might try to figure out how these magics could be applied in his own world. Arthur would focus more on the social aspects. For example, he would understand the concept of houses in Hogwarts in terms of loyalty and group identity, much like how he views his knights. He would also be able to relate to the idea of fighting against dark forces, as he has his own battles in his realm.
One idea could be that Merlin uses his ancient magic to shield Harry Potter from Voldemort's attacks when he was just a baby. Maybe he creates a magical barrier around the Potter's house that not even the Dark Lord can penetrate. This would be a great twist on the original story as it brings in a whole new element of magic from a different magical realm.
Well, in some 'harry potter reincarnated fanfiction', an interesting idea is that Harry is reincarnated into the body of a Death Eater. This flips the whole good - bad dynamic on its head. He has to deal with the prejudices of those around him who think he's still a bad guy while trying to atone for the actions of his new body's past. It's a really cool concept that adds a whole new layer of complexity to the story.
The prophecy about Harry and Voldemort would take on a new meaning. If Merlin was in Harry, he might see the prophecy as just another part of the cycle of good vs. evil that he has already experienced in Camelot. He would approach the battle with Voldemort with a different strategy, perhaps using his knowledge of ancient magic to find a more permanent solution to the dark wizard threat.
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.
One idea could be that Merlin somehow gets transported to the Harry Potter universe. He could use his magic, which is different from the wizarding magic in Harry Potter, to solve some of the mysteries or problems there. Maybe he teams up with Harry and helps him defeat Voldemort in a unique way, like using his ancient magic knowledge.
One interesting idea could be how the magic from Merlin's time influences the wizarding world in Harry Potter. Maybe there are ancient spells or magical artifacts passed down through Merlin's inheritance that play a crucial role in the fight against Voldemort.
One idea could be a crossover where Harry Potter, through some magical mishap, gets transported to the time of Merlin and Morgana le Fay. He could find himself in the middle of their power struggle, and his modern magic knowledge might either help or hinder the situation. For example, his knowledge of defensive spells could be useful against Morgana's dark magic attacks, but his lack of understanding of the ancient magic rules could also get him into trouble.
