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.
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.
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.
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.
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.
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.
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.
In this kind of fanfiction, Edward might try to change the past events that led to his and his brother's misfortunes. Maybe he'd prevent the failed human transmutation in the first place, saving Alphonse from losing his body.
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.
