One interesting one could be a crossover with 'Sherlock Holmes' where Harry Potter becomes a teacher at Hogwarts and Sherlock Holmes is brought in to solve a mystery on the school grounds. The contrast between the magical world and Holmes' deductive reasoning makes for a great story.
Well, if Ed was a teacher in a FMA - Harry Potter crossover fanfic, it could be really interesting. He might teach alchemy in Hogwarts. Imagine him trying to explain the principles of alchemy to the wizards, who are used to magic in a different way. He could get frustrated with the lack of understanding at first, but eventually find students who are really into it. He might also have some run - ins with the more traditional teachers who don't quite understand his methods.
I'm not entirely sure if there is a specific 'Harry Potter is a teacher' scenario within Twilight fanfiction. Twilight and Harry Potter are two very different universes, and while fanfiction can be quite creative and cross - over in strange ways, this particular combination seems rather unusual.
If Harry is a teacher in a crossover with 'Percy Jackson', he might introduce different ways of using magic that could influence the demigods. This would change the way they approach their quests and battles, as they now have new magical knowledge from Harry.
In a crossover fanfic, Ed might teach a class on the practical applications of energy manipulation. Alchemy in FMA is all about understanding and controlling energy. He could show the Hogwarts students how to use their magic in more efficient and creative ways, similar to how he uses alchemy. For instance, he could teach them how to focus their magic energy for a more powerful spell, just like he focuses his alchemical energy for a difficult transmutation.
It could work by having Ed teach a unique subject that combines elements of both FMA and Harry Potter. For example, a class on magical alchemy. He would use his knowledge from FMA to introduce different techniques and concepts that the students of Hogwarts have never seen before. His presence would also create some interesting interactions with the existing characters in the Harry Potter universe, like Dumbledore or Snape.
Sure, it's quite possible. Fanfiction writers love to blend different fictional worlds. In a 'The Mummy (2017)' and 'Harry Potter' crossover, we could see the mummy's powers being pitted against the spells of Hogwarts students. Maybe the mummy is brought back to life in the wizarding world and causes chaos. There are endless possibilities for interesting storylines in such a crossover fanfiction.
One idea could be that Tinkerbell finds her way into the wizarding world of Harry Potter. Maybe she gets accidentally transported there by some magical mishap. She could use her fairy magic in Hogwarts, like helping to repair broken objects in a more sparkly and unique way compared to the Reparo charm.
A popular one is 'Fem Harry and the World of Middle - earth'. This fanfic is really interesting because it crosses over the Harry Potter universe with Tolkien's Middle - earth. Here, Fem Harry has to adapt to the very different cultures and magic systems in Middle - earth, and there are some great character interactions that add depth to the story.
Yes, it could be. It's a very interesting and unique concept. Combining Harry Potter with the Riddler from Batman is quite unexpected. It might involve putting Harry Potter in a situation where he has to solve riddles like the Riddler creates, or perhaps there are elements of mystery from the Riddler's world incorporated into the magical world of Harry Potter.
