The time - travel or cross - time - line aspect is often unique. Fanfic authors like to play with the idea of Merlin being in the 'Harry Potter' time or vice versa. This allows for interesting interactions between characters from different eras. For instance, Merlin teaching Harry some long - lost magic that was forgotten over the centuries. Also, the way they handle the power levels of Merlin compared to the powerful wizards in 'Harry Potter' is unique. Merlin is often depicted as extremely powerful, so seeing how he would interact with Dumbledore or Voldemort is always fascinating.
A really good 'Harry Potter Blessing Merlin' fanfic is 'Merlin's Legacy in the Wizarding World'. This fanfic delves deep into how Merlin's magic might have influenced the world of Harry Potter that we know. It has a complex plot where secrets about Merlin's past are slowly uncovered and how they impact the present day in the Harry Potter universe. The author does a great job of building a connection between the two fictional worlds.
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.
In Harry Potter and Merlin fanfics, a Team Muggle Resurgence could be really interesting. It might involve muggles suddenly developing some sort of power or resistance against the wizarding world's dominance. Maybe they start to use their own technology and knowledge in ways that wizards can't anticipate, like using modern electronics to disrupt magic or something.
I'm not sure specifically as there could be many different interpretations in fanfics. But generally, it might explore Harry Potter having a connection to Merlin, perhaps inheriting some of Merlin's powers or facing challenges related to that heritage.
One great 'Merlin and Harry Potter' crossover fanfic is 'The Merlin Effect in Hogwarts'. It combines the magic systems of both universes really well. The characters from Merlin, like Merlin himself, fit surprisingly well into the Hogwarts setting. They interact with Harry and his friends in interesting ways, for example, Merlin uses his unique magic to solve some of the problems at Hogwarts that the students there are facing. It's a fun read for fans of both series.
First, you need to be familiar with both universes. Know the characters, their personalities, and the rules of magic in Merlin and Harry Potter. Then, think of a unique concept for the crossover. For example, a magical accident that transports a character from one world to the other. Next, plan how the characters will interact. Will they be friends? Rivals? And don't forget about the plot. It should be engaging and make use of the combined elements of both worlds. For instance, a mystery that can only be solved by using magic from both Merlin and Harry Potter universes.
Maybe he finds it in a hidden chamber at Hogwarts. There could be some ancient magic protecting it, but Harry, with his knack for getting into trouble and finding things, stumbles upon it.
It could be a previously unknown student at Hogwarts. Maybe a shy Ravenclaw who has always been good at spells that require great intelligence and wisdom, which are traits often associated with Merlin.
Merlin could be integrated as a forgotten ancestor of one of the main characters. For example, if he was an ancestor of Hermione, it could explain her extraordinary intelligence and affinity for magic.
