Well, a common theme is growth. Both Ed and Rose grow as individuals throughout their relationship in fanfiction. They learn from each other. Ed might teach Rose about alchemy's potential for good, and Rose can show Ed the value of simple human kindness. Another theme could be the idea of hope. In a world full of despair like in 'Fullmetal Alchemist', their relationship can symbolize hope for a better future. Fanfic writers often play with the theme of cultural differences too. Since they come from different backgrounds, it adds an interesting dynamic to their relationship and the stories that can be told.
Some fanfictions focus on the theme of acceptance. Ed has his own insecurities due to his short stature and his past mistakes in alchemy. Rose, having faced hardships herself, can be the one to fully accept him. Love in the face of danger is also a theme. Given the many threats in the 'Fullmetal Alchemist' world, their love can be a source of strength. And then there's the theme of identity. As Ed is an alchemist and Rose is a civilian, they both have different identities that can either clash or blend together in interesting ways in fanfiction.
One popular theme is the exploration of their different worlds. Ed from his alchemist - filled world and Rose from her more ordinary, yet war - torn world. Their relationship can be a way to bridge these two very different existences. Another theme is sacrifice. In the context of the 'Fullmetal Alchemist' universe, both characters have had to make sacrifices, and in fanfiction, this can be explored further in relation to their relationship. Also, the theme of redemption often comes up. Rose has seen a lot of pain and suffering, and Ed, with his quest for the Philosopher's Stone, might see his actions as a way to redeem himself in her eyes and the eyes of the world.
Another theme is adventure. They go on various quests together in the 'Fullmetal Alchemist' universe. Maybe they are searching for a way to reverse the results of a forbidden alchemy or to stop an evil alchemist. During these adventures, their bond strengthens. In some fanfictions, they face life - threatening situations which make them realize how much they mean to each other.
Another reason is the 'forbidden' aspect of their relationship. Envy is a Homunculus, and Ed is a human alchemist. In the world of Fullmetal Alchemist, such a relationship would be frowned upon. But in fanfiction, this taboo nature makes it all the more exciting to explore. It allows writers to break the norms of the original story and create unique and interesting storylines that involve the two characters defying the odds and coming together in different ways.
One possible aspect to consider in this fanfiction could be the character development of ED and AL. Their relationship in the original series is very deep and in the fanfiction, it might explore new dimensions of their bond, perhaps in different scenarios or alternate universes.
In a fanfiction, perhaps there's a misunderstanding between Ed and Winry. Winry thinks Ed has feelings for another girl because he's been spending a lot of time with a female alchemist. Ed is oblivious to Winry's concerns at first, but when he realizes, he has to find a way to prove to Winry that she's the only one for him.
There are many fanfictions where Ed is portrayed as a girl. Fanfiction writers like to play with the existing characters in new ways. By making Ed a girl, they can introduce new themes and perspectives. For example, it could change how the story deals with gender roles in the world of Fullmetal Alchemist. Also, it can create new emotional arcs for the character, as a female Ed might face different challenges and experiences compared to the male version in the original story.
One common theme is the unspoken love between them. They've known each other for so long that their feelings might be there but not fully expressed at first. Another theme is the way they rely on each other. Ed depends on Winry for his automail maintenance, and Winry counts on Ed to bring her new challenges in automail design. Also, the theme of growth is prevalent. As they face different challenges in the world of alchemy and automail, they grow both individually and in their relationship.
One common theme is love and relationship development. Since they've known each other for a long time, fanfics often explore how their feelings change from friendship to something more romantic. Another theme is family, as Winry was like family to Ed when they were growing up, and fanfics may play with that dynamic in their relationship.
In Ed and Winry fanfiction, a prevalent theme is the contrast between their personalities. Ed is hot - headed and impulsive, while Winry is more level - headed and practical. This contrast can lead to interesting interactions and relationship dynamics. Additionally, the theme of family is important. Since they grew up together, they have a family - like connection that can be explored in different ways, such as how they protect and care for each other like family members. Another theme could be the exploration of their dreams. Ed's dream of restoring his and Al's bodies through alchemy and Winry's dream of becoming a top - notch automail mechanic can be intertwined in fanfiction.
The complex relationship between Roy and Ed in the original series. Roy is a military man with his own goals and Ed is a young alchemist with a strong will. Their interactions, which can be seen as a mix of rivalry and mutual respect, are interesting to explore in a romantic or more intimate context in yaoi fanfictions.
One great Envy x Ed fanfiction is 'The Unlikely Bond'. It explores how their complex relationship could develop in an alternate universe. The story delves deep into their characters, showing how Envy's envy (pun intended) towards Ed's humanity could turn into something more. It has some really interesting dialogue that stays true to their personalities from the original series.
