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.

A bad Fullmetal Alchemist fanfic often has a weak or non-existent plot. If the story doesn't have a clear beginning, middle, and end, or if it's just a random collection of events, it's likely not well-written.
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 might be such fanfics in the vast world of fanfiction, but it goes against the original canon of the 'Fullmetal Alchemist' series as male pregnancy is not a part of the normal story. However, some fanfic authors like to explore very unconventional and out - of - the - box ideas.
I really liked 'A Reader in the Homunculi World'. In this fanfic, the reader is thrown into the world of Fullmetal Alchemist and has to deal with the homunculi in various situations. It has a lot of action and mystery elements. It shows how the reader tries to survive and understand the complex nature of the homunculi. Also, the character development throughout the story is quite engaging.
One great 'Fullmetal Alchemist Scar Crossover Fanfic' is 'Scar's New Path'. It takes Scar on an adventure where he teams up with characters from another universe. The story is really engaging as it delves into Scar's character development in this new and strange setting.
