Edward might be a protector. Given his skills and determination, he could use his alchemy to create defenses for the werewolves or protect the Hogwarts community from any threats related to werewolves. He would be like a guardian, using his abilities in new and creative ways within the Hogwarts setting.
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.
Well, if Edward Elric were in a Hogwarts werewolf fanfiction, it could be really interesting. Maybe he'd use his alchemical skills to try and find a cure for the werewolf curse. He's a smart and determined character, so he might not just accept the werewolf situation as it is. He could also form an unlikely friendship with the werewolves in Hogwarts, perhaps using his knowledge to help them control their transformations better.
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.
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, 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.
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.
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.
Perhaps it's a story where Naruto has the same kind of tragic backstory as Edward. Maybe Naruto loses Sasuke in a way similar to how Edward lost his mother and brother's body. So Naruto starts to study alchemy in the hope of getting Sasuke back. Along the way, he meets Edward and they learn from each other's experiences and fighting styles, and together they face the challenges in both their worlds.
He'd adapt by using his intelligence. Edward is used to dealing with complex situations in his own world. At Hogwarts, he'd start observing how magic works and try to make sense of it. He might compare it to alchemy in his head and find similarities. For example, the way a spell is cast might remind him of how an alchemical reaction is set in motion.
One possible plot could be that Edward Elric discovers Ki as a new form of energy. He might initially struggle to understand and control it, like he did with alchemy. He could meet a mentor who teaches him the basics of Ki, and then he uses this new knowledge to face his enemies in a different way, perhaps even combining Ki with his alchemy skills.
