What could be the plot in the 'Edward Elric learns Ki' fanfiction?

There could be an organization that wants to keep Ki a secret from the world of alchemy. They see Edward's attempts to learn Ki and potentially bridge the gap between the two as a danger. So, the leaders of this organization send their agents to stop Edward, and the most powerful of these agents could be the main antagonist in the fanfiction.

In this fanfiction, the plot could center around Edward trying to understand and control a mysterious new type of energy. He could be on a quest to find the source of this energy. Along the way, he meets new characters, some of whom help him while others try to stop him from achieving his goal of mastering this energy.

It could be another alchemist who wants to use this new energy for evil purposes. This alchemist might see Edward as a threat to his plans and constantly try to stop him from learning more about the energy.

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.

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.

One possible plot could be that Edward, now as a girl, has to deal with the different reactions of his friends. For example, Alphonse might be a bit confused at first but quickly adapts and becomes very protective. Edward could also face new challenges in his alchemical studies as some traditional alchemy is male - dominated. And he might have to struggle with his own self - identity, trying to figure out if he still has the same goals and values as before the transformation.

In some fanfictions, Edward Elric might gain the ability to manipulate time. This could be a really cool addition as it would allow him to go back and correct mistakes he made in his past, like the failed human transmutation that cost him his arm and leg.

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.
