One interesting plotline could be Envy's relationship with other female characters in the Fullmetal Alchemist world. Maybe she forms an unlikely alliance with a female alchemist. This could lead to a journey of self - discovery for Envy as she experiences different emotions through this new connection.
A possible plotline is Envy getting involved in a political intrigue within the story's setting. As a female Envy, she might use her unique abilities to manipulate the political situation. For example, she could be in the middle of a power struggle between different military factions, adding her own devious plans to the mix.
Edward could be a great character to pair with Female Envy. Their interactions would be full of tension and conflict, given their different natures. Edward's strong sense of justice and Envy's devious ways would create a lot of interesting scenarios.
One popular theme is the exploration of Envy's complex personality in the crossover. Since Envy is a homunculus with deep - seated issues like envy (obviously), in a crossover, it could be interesting to see how that plays out against new characters or new settings from the other fandom. Another theme could be the struggle for power. Envy often desires power in the Fullmetal Alchemist universe, and in a crossover, this could be magnified or redirected depending on the nature of the crossover. Also, themes of redemption are possible. Despite being a villain, Envy has moments of self - realization, and a crossover could explore if and how Envy could be redeemed in a different fictional context.
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.
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.
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?
Imagine a scenario where Naruto and Edward Elric switch bodies. At first, they are both frustrated and confused, but as they try to adapt to each other's lives, they also start to understand each other on a deeper level. Edward, in Naruto's body, meets Hinata and is touched by her kindness. Meanwhile, Naruto, in Edward's body, gets to know Winry better. Through this body - swap experience, two romantic relationships could develop - one between Edward (in Naruto's body) and Hinata, and another between Naruto (in Edward's body) and Winry.
Another theme could be Envy's relationship with other Homunculus. Writers can create stories about their power dynamics, rivalries, or even unexpected alliances in a family - friendly way. It can be really interesting to see how Envy interacts with Lust or Gluttony in different scenarios.
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.
One idea could be exploring Lust's backstory before she became a Homunculus. Maybe she had a human life before and what led to her transformation. Another could be a fanfiction where Lust forms an unlikely alliance with a human alchemist. They could work together to achieve a common goal, like saving a town from a greater evil.
