If Edward Elric were transported to Hogwarts, he'd likely become friends with Hermione. They both have a thirst for knowledge. Edward could teach her about alchemy, and she could teach him about magic. He'd also be really interested in the potions class, given his background in alchemy. And he might get into some trouble for trying to 'improve' on the potions with his alchemical knowledge.
Edward Elric in Hogwarts would be a bit of an outcast at first. His mechanical arm and leg would be very different from what the students are used to. But his skills in combat, which he learned through his alchemical adventures, would make him a formidable opponent in any wizard duels. He might also be fascinated by the magical creatures at Hogwarts and try to study them from an alchemical perspective.
Well, Edward Elric in Hogwarts would be quite a sight. He'd probably be super confused at first. I mean, going from his world of alchemy to a world of magic. He might try to use alchemy where magic is required and get some really strange looks. But he's a smart guy, so he'd quickly start to learn about magic. Maybe he'd even find a way to combine alchemy and magic in some unique way.
In this kind of fanfiction scenario, there could be a lot of interesting things. Edward's alchemical knowledge might be translated into some unique magical concepts at Hogwarts. For example, he could introduce new ways of thinking about transfiguration, seeing it through the lens of alchemy's transformation principles. He might also have trouble adjusting to some of the pure magical ways of Hogwarts, as he is used to his own world's rules. And his relationship with the students could be very different, perhaps more hands - on and direct compared to the traditional Hogwarts professors.
Well, perhaps Edward could use his alchemy skills in the magical world of Hogwarts. He might be sorted into Gryffindor for his courage. He could start to learn magic along with the Hogwarts curriculum and have some interesting interactions with the students like Harry, Hermione and Ron. Maybe he'd show them some unique alchemy tricks and in turn learn some new spells.
They could start by comparing their different worlds. Edward would explain about the principles of alchemy like equivalent exchange, while Urahara would talk about the Soul Society and the way spiritual power works. This exchange of knowledge could be the foundation for their relationship in the fanfiction.
He could be a researcher. He'd study the werewolves at Hogwarts, trying to figure out the nature of their transformation. His alchemy knowledge would give him a unique approach.
One possible outcome is that Naruto would gain a different perspective on alchemy. Edward's scientific approach to combat and his understanding of equivalent exchange could influence Naruto's way of thinking. Naruto might start to analyze his jutsu in a more methodical way, similar to how Edward approaches alchemy. For example, he could consider the energy input and output of his shadow clone jutsu more carefully.
If Edward Elric taught at Hogwarts, it would be a wild ride. He's used to a different magical system in his own world. He could bring in concepts like equivalent exchange to the Hogwarts curriculum. His experience with his own dark and dangerous adventures would give his teaching a sense of urgency and real - world applicability that Hogwarts students might not be used to. He might have some clashes with the more traditional Hogwarts professors at first, but eventually, they'd see the value in his different perspective.
Well, when it comes to interacting with the Hogwarts professors, Edward Elric would likely approach them with his usual inquisitive nature. With Professor McGonagall, he'd be impressed by her transformation magic and might ask her if there's any connection to alchemy's transmutation. He could have some interesting debates with Professor Flitwick about the nature of magic and how it differs from alchemy. And with Hagrid, Edward might be a bit cautious at first, but then warm up to him when he realizes Hagrid's kind heart.
If Edward Elric becomes Pride in fanfiction, it could lead to a really interesting plot twist. His alchemy skills might be warped in a new and dangerous way. Instead of using alchemy for good, like he usually does, he could start using it for Pride's more self - serving and malevolent purposes. Also, his physical form might change to something more in line with what Pride is like in the original story. This could make for some really intense fight scenes, especially if he has to face off against his former allies who now see him as a threat.
In fanfiction where Edward Elric becomes a Homunculus, his appearance would likely change. He might have the characteristic red eyes of a Homunculus. His physical abilities would be enhanced, but at the cost of his humanity. He'd be more connected to the Homunculus' plans and goals, perhaps being forced to work against his former comrades. However, he could also use his new position to try and undermine the Homunculus from within, but it would be a difficult and dangerous path to take.
Edward might meet his parents. Since he has the chance to go back in time, he could meet them when they were alive and perhaps learn more about alchemy from them, which could change his future actions.
