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.
The time span covered in the story of Fullmetal Alchemist varies depending on different plot arcs and character developments. But roughly, it covers several years of the characters' lives.
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.
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.
Fullmetal Alchemist does continue in manga form. However, the continuation might not follow the exact same pace or style as the original series. It might introduce new plotlines and character developments.
