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.
In such a fanfic, Ed as a teacher would bring a whole new dynamic. Since he has his own set of skills and a no - nonsense attitude. He could be teaching a class that combines both alchemy and magic. Maybe he'd be like a special guest teacher brought in to introduce new concepts. He would probably use his automail arm to demonstrate some of the more physical aspects of alchemy. And his relationship with the students could range from being a strict mentor to a friend who they can come to with their problems.
If Ed were a teacher in this crossover fanfic, he would likely be a very unconventional one. His teaching style would be based on his own experiences in the world of FMA. He might not be too fond of the Hogwarts rules and regulations at first. But as time goes on, he could start to adapt. He could introduce the idea of equivalent exchange to the students, which could be a completely new concept for them. This could lead to some really cool storylines where the students start to experiment with alchemy - like magic, and Ed has to guide them through the process.
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.
One possible fanfic could be 'Ed's Magical Adventure in Hogwarts'. In this, Ed uses his alchemical skills in the wizarding world. He might teach the students about different ways of manipulating matter, which is quite similar to magic in some aspects. For example, he could show how to transform basic elements, just like a transfiguration spell.
It could be a story full of surprises. The Boggart might take on forms related to the FMA world, like the homunculi, which would be really strange for the Harry Potter characters. And for EDS, Edward might have to figure out how to use his alchemy without drawing too much attention in the wizarding world. He could end up using it in a very discreet way to defeat the Boggart. For example, he might transmute a small object in his pocket into a tool to scare the Boggart away.
In a fanfic with this crossover, the interaction of the magic systems would be a central and fascinating aspect. Alchemy in FMA has its own set of rules and limitations, as does magic in Harry Potter. When it comes to the Boggart, the Harry Potter characters rely on their spells and the power of their minds to change the Boggart's form into something humorous. Edward, with his EDS status, could bring in the concept of equivalent exchange. Maybe he could offer something in exchange for the Boggart to leave or change its form in a more permanent way. And the magical energy in the Harry Potter world could interact with Edward's alchemy. It could either disrupt it if they are too different, or it could merge in some ways, allowing for new and creative ways to deal with threats like the Boggart.
One popular fma Harry Potter crossover fanfiction might involve Ed's unique alchemy skills being transferred to the Harry Potter world. For example, he could use his knowledge to create magical items in a different way than the wizards are used to. Another aspect could be how Ed, as an ambassador of sorts, tries to bridge the gap between the two very different worlds of Fullmetal Alchemist and Harry Potter, perhaps leading to some interesting cultural exchanges within the story.
One common theme could be the clash of different magical systems. In Harry Potter, there's the magic based on spells and potions, while in FMA there's alchemy. Another theme might be the exploration of different cultures and values. The pride aspect could also play into characters showing their unique identities and abilities from both universes.
One idea could be that characters from Fma use their alchemical skills in the wizarding world of Harry Potter. For example, Edward could try to transmute a magical object using his knowledge of equivalent exchange. Another plot idea might be that the Philosophers Stone from Harry Potter has some connection to the alchemy in Fma, and characters from both universes have to work together to protect it from dark forces. Also, perhaps a character from Fma gets sorted into one of the Hogwarts houses and has to adapt to the magical school life while still having their own alchemical powers.
Some characters from Fma would approach the magical creatures with a sense of wonder and a desire to learn. They would try to find alchemical explanations for their abilities. For instance, a character might see a Phoenix and wonder if its ability to be reborn is related to some form of alchemical regeneration. They would also likely compare the magical creatures to the chimeras and other strange creatures they are familiar with in their own world. This would lead to some interesting cultural exchanges between the two universes as they try to understand and interact with the magical creatures.
Well, a cool plot could be that the Death Eaters are interested in the power of alchemy. They try to capture Edward to force him to use alchemy for their evil purposes. Harry, Ron, and Hermione then rescue him. In return, Edward offers to help them with his alchemical skills in their fight against Voldemort. For example, he could use alchemy to create unique magical items or barriers. Also, Alphonse could befriend some of the Hogwarts ghosts and learn about the secrets of the castle from them, which could be useful in the fight against the dark side.
