There are fanfictions that explore the moral aspects of both universes. In My Hero Academia, there's the concept of using powers for good or bad, and in Fullmetal Alchemist, the idea of equivalent exchange. A fanfiction might combine these, like a hero in My Hero Academia who has to face the consequences of not following the equivalent exchange rule when using their quirk.

Create well - developed characters. You can take existing characters from both series and give them new traits based on the combination of the two worlds.
