The theme of identity is quite common. The Homunculi are not human but they might question their existence and purpose, and Roy Mustang's presence can either help or hinder that self - discovery. Also, themes of loyalty come up, like whether a Homunculus can be loyal to Roy Mustang or vice versa.
Yes, there are quite a few. Some explore alternative storylines where Roy Mustang has unexpected interactions with Homunculi. For example, in one fan fiction, Roy Mustang teams up with a Homunculus against a common enemy, which completely changes the power dynamics in the story.
The theme of trust is crucial in these fan fictions. Given their different positions and goals, they need to trust each other fully. Fan fictions often explore what could break that trust and how they can repair it. For instance, if Edward discovers Roy has been keeping secrets for the sake of the military, it could lead to a rift in their relationship that they have to overcome.
One aspect of Edward Elric x Roy Mustang fan fiction could be the exploration of their unique relationship dynamics. Given their different personalities in the original series, fan fictions might focus on how they complement each other. For example, Edward's impulsive nature and Roy's more calculating approach could create interesting scenarios.
One popular theme is friendship development. Many fanfictions focus on how Edward and Roy Mustang start off as distrustful of each other and gradually become friends. For example, stories might show them working on a project together and slowly realizing they have more in common than they thought. Another theme is power dynamics. Given Roy's position in the military and Edward's unique alchemical abilities, exploring who has more influence in different situations is quite common.
One of the main themes is power and its consequences. Roy Mustang has great power as a State Alchemist, and the light novels often explore how he uses it and what the ramifications are. Another theme is loyalty, both to his comrades and to his ideals.
One common theme is power and ambition. Since Roy Mustang is a character associated with power (his fire alchemy) and his ambition to rise in the military, many OCs are created to either complement or contrast with that. For example, an OC might have a power that can either enhance or hinder Mustang's own power, and their interactions revolve around how they deal with power dynamics.
Another option could be 'The Hitchhiker's Guide to the Galaxy'. It's a humorous take on science fiction, filled with absurd situations and unique alien races. The idea of the 'Answer to the Ultimate Question of Life, the Universe, and Everything' being 42 is both comical and strangely profound.
Well, exploration is also a common theme. Fan fictions may take Miss Mustang to new places, whether it's a mysterious island or a far - off planet. Additionally, the theme of family can also be found, such as stories about her family history or finding long - lost relatives.
A sense of justice is another common theme. They both strive for a just world in their own ways. In fanfiction, this can lead to them teaming up to fight against corrupt forces or unfair systems. Their different approaches to achieving justice, Roy's more political and Edward's more hands - on, create interesting dynamics in the stories.
One interesting plot idea could be that Roy and Edward have to team up on a secret mission that involves alchemy and military strategy. They start off not getting along well because of their different personalities and approaches, but as the mission progresses, they learn to respect each other and become friends. Another idea is that Edward discovers a new form of alchemy that Roy is interested in for military use, and they have to work together to keep it from falling into the wrong hands.
