Fanfictions that involve crossovers can also be interesting. For example, a crossover between Fullmetal Alchemist and another popular anime like Naruto. It could be a story where the characters from both series have to work together to solve a common problem, like a new type of threat that combines the elements of chakra and alchemy.
There could be a fanfiction where 'the watch' is a key element in a mystery. For example, the watch is found at a crime scene in Amestris. The Elric brothers then get involved in solving the mystery behind the watch, which could lead them to discover a new form of alchemy or a secret organization. In this fanfiction, the watch might have symbols on it that are related to ancient alchemical knowledge.
One interesting fanfiction could be where characters from Naruto and Fullmetal Alchemist are brought together in a new world. For example, Naruto characters might find themselves in Amestris and have to deal with the alchemy laws there. They could team up with the Elric brothers to fight a common enemy that threatens both their worlds.
One great fanfiction could be where they go on an adventure together to find a rare alchemical ingredient. It could show their relationship growing as they face challenges side by side. Edward's determination and Winry's mechanical skills would complement each other during the journey.
Another idea might be alternative endings. Fanfiction often plays with the concept of 'what if' things had gone differently. Maybe if Edward had not been able to regain his brother's body, how would he have coped and what new path would his life take?
There are several good ones. 'The Alchemist's Redemption' is a great fanfiction that delves deeper into Edward's internal struggle with his past actions as an alchemist. 'Mustang's Ascent' is another that follows Roy Mustang's journey to the top of the military ranks with some interesting twists on his relationships with other characters. And 'The Homunculus Within' which explores the nature of homunculi in a more philosophical way than the original series.
One great Ed x Roy fanfiction is 'The Alchemical Bond'. It delves deep into their complex relationship, exploring how their different personalities interact. The story has a lot of character development and some really interesting plot twists that keep you hooked. Another one is 'Flames of Friendship'. It focuses more on the early days of their acquaintance and how they gradually grow closer through their shared experiences in the world of alchemy.
There's also 'A Different Kind of Alchemy'. This fanfic focuses on how they collaborate on a secret alchemical project that no one else in the military knows about. It's filled with suspense as they face various obstacles together, and through that, their relationship blossoms. It's a great read for those who like a bit of mystery in their fanfictions.
One interesting fanfiction could be where Edward and Alphonse travel to a parallel world. In this world, they have different roles and challenges to face. It shows a different side of their characters as they adapt to this new environment.
One interesting fanfiction could be about Harry Potter somehow ending up in the Fullmetal Alchemist world and learning alchemy. He might use his magic in combination with alchemy in unique ways to solve problems.
One interesting concept could be the combination of different alchemical abilities from various characters in different universes. For example, if a character from another anime with a unique power system crosses over into the Fullmetal Alchemist world, it could lead to new alchemical reactions and techniques. Another concept might be the exploration of how different cultures and moral codes interact. Characters from different fictional worlds might have different views on equivalent exchange, which could create some really thought - provoking scenarios. Also, the idea of crossovers can introduce new relationships between characters. Characters who have never met before might form alliances or rivalries based on their own goals and personalities.
