One great fanfiction could be about Izumi's backstory before she became an alchemist. It might explore her early training days and the challenges she faced. For example, a story could focus on how she overcame the difficulties of learning complex alchemical theories without proper guidance at first.
Her relationship with other characters is also a great aspect. In fanfiction, writers can develop her friendships or rivalries further. For example, her interactions with the Elric brothers could be delved into more deeply, showing different sides of her personality through these relationships.
A unique plot. For example, if it combines the mystery of Babylon with the complex alchemy system of Fullmetal Alchemist in an unexpected way. Maybe it could explore a hidden aspect of Babylon within the Fullmetal Alchemist universe that hasn't been much explored before.
Some characters might be quite shocked or amused if they could read fanfiction about their own story. For example, Edward Elric would probably be very indignant at some of the out - of - character portrayals of himself. He's a proud alchemist and seeing himself depicted in a way that doesn't match his self - image would surely make him fume.
Yes, it is. The manga has a perfect balance of action, drama, and philosophy. The themes explored are profound, and the character growth is very satisfying.
There probably are. Fanfiction writers often love to mash up different universes. In such a fanfic, Naruto could bring his chakra - based powers and blend them with the principles of alchemy from Fullmetal Alchemist. Maybe he'd use his Rasengan in a new way by incorporating alchemical transmutation circles. It would be a wild and creative concept.
