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.
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.
Yes, there might be some out there. However, it's not a very common combination. You'd have to search through various fanfiction platforms. Some might explore the idea of Merlin - like characters in the Kingsman universe interacting with the magical world of Harry Potter in unique ways, but it would be a very niche sub - genre within fanfiction.
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.
Yes, there are likely some out there. Fans often create crossover fanfics that combine different universes like 'Hitman' and 'Harry Potter'. These can be really interesting as they blend the magic and mystery of 'Harry Potter' with the stealth and assassin - like nature of 'Hitman'.
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.
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.
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.
