One common theme is redemption. Since they've both made mistakes in their alchemical pursuits, fanfictions often explore how they try to make up for those mistakes in different scenarios.
The dynamic between Edward and Alphonse in fanfics is quite interesting. They are brothers, but also partners in alchemy. Edward is the more active and often impulsive one, while Alphonse is more reserved. Fanfics may play with this dynamic, like having Alphonse be the voice of reason when Edward is about to rush into a dangerous situation.
In many Fullmetal Alchemist fanfics, the relationship between Edward and Alphonse is often portrayed as a deep and unbreakable bond. They have been through so much together, from the failed human transmutation to their adventures in search of the Philosopher's Stone. Fanfic authors may explore their brotherly love further, showing how they support each other in different situations, whether it's facing powerful enemies or dealing with the moral dilemmas that alchemy often presents.
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 possible fanfiction could be about Edward and Roy teaming up for a dangerous mission. Maybe they have to infiltrate an enemy stronghold where they discover a new type of alchemy that they've never seen before. Along the way, they start to understand each other better and respect the other's skills.
Well, in fanfiction, Edward and Roy's dynamic can be really interesting. They have different personalities. Edward is young and impulsive, while Roy is more reserved and calculating. This contrast can lead to some really engaging storylines in fanfiction, like when they work together on a mission and Edward's quick actions either save or almost ruin the plan.
Maybe Edward dies in a fight against a powerful new enemy. This enemy could be someone who has mastered a dark form of alchemy that Edward couldn't counter. His death could then inspire the other characters, like Winry, to take up arms in a different way. She might use her skills as an automail engineer to create weapons that can defeat this new threat, all while mourning Edward and vowing to make his death count.
One common theme is identity. Since Edward is a male in the original, making him female in fanfiction often leads to exploring how this change affects his self - identity. Another theme is relationships. It could be how his relationships with other characters like Alphonse, Winry, or Roy Mustang are different because of the gender change. For example, a female Edward might have a different dynamic with Winry in terms of friendship or rivalry.
Often, fanfiction writers focus on the character growth that can occur through their interactions. Edward, who starts off as a headstrong and somewhat naive alchemist, can learn a great deal from Roy's strategic thinking. Roy, in turn, might be inspired by Edward's unwavering belief in doing what's right, regardless of the consequences. Their relationship could also be a source of conflict, as their personalities and goals don't always align.
If Edward dies, it would have a huge impact on Alphonse. Alphonse has always relied on Edward, and without him, he would be lost at first. But this could also be a turning point for Alphonse to become more independent and find his own path in life. He might start to question the things they've been doing in their search for the Philosopher's Stone and find a new purpose.
