Yes, there are likely fanfictions out there with such a concept. The worlds of Naruto and Fullmetal Alchemist, where Edward Elric comes from, are quite different, but that's what makes the idea of a crossover in fanfiction so interesting. Writers might explore how Naruto's ninja world and its unique powers could interact with Edward's alchemical abilities and the complex world of Amestris.
Alphonse Elric is often present. He might play a role in helping Edward understand and use his new gamer - like abilities in relation to alchemy. For example, he could be the one who discovers a new aspect of Edward's powers.
Edward might meet his parents. Since he has the chance to go back in time, he could meet them when they were alive and perhaps learn more about alchemy from them, which could change his future actions.
One common theme is identity. Since Edward is now female, there's often exploration of how she reconciles her new identity with her well - known male counterpart's actions and reputation. Another theme is relationships. How does a female Edward interact with characters like Alphonse, Winry, or Roy Mustang differently? And of course, there's the theme of adaptation. How does she adapt to the challenges of the FMA world, which was initially centered around a male - dominated narrative.
In fanfiction, the possibilities are nearly endless. Regarding Edward Elric becoming a homunculus, it could be a very interesting concept. If he were to become one, it would completely change his relationship with other characters. For example, his brother Alphonse might react in a very different way. Also, Edward's own view of himself and his abilities would be transformed. His struggle with his new form, if it were to happen, could be a central theme in the fanfiction. Maybe he would try to find a way to reverse the process, or perhaps he would embrace his new existence as a homunculus. It all depends on the creativity of the fanfiction author.
The challenges she faces can also be different. In the original story, Edward had his own set of difficulties as a male alchemist. As a female, she might face additional discrimination or different expectations in the world of alchemy. Fanfictions can explore how she overcomes these new challenges while still trying to achieve her goals like getting their bodies back (if following the main plot of the original story).
There are many ways to approach an emotionless Edward Elric in fanfiction. Some writers might focus on how he still manages to be a brilliant alchemist without the ability to feel. Others might explore the internal struggle within him as he tries to understand what has been taken from him. It really depends on the writer's creativity and the direction they want to take the story.
One great 'Edward and Alphonse Elric Fanfiction' is 'The Brothers' Bond'. It really delves deep into their relationship, showing how they support each other through various challenges. Another interesting one is 'Alchemy's Sons'. It explores their journey in a different light, adding new elements to their story.
One idea could be a story where Edward's friends throw him a surprise birthday party. They decorate the alchemy lab with streamers and balloons. Alphonse secretly bakes a cake with the help of Winry. Everyone gathers around as Edward walks in, completely shocked and overjoyed at the sight.
Yes, there are some out there. You can start by looking on popular fanfiction websites like Archive of Our Own. Just search for 'Edward Elric is a sniper' and you'll likely find a variety of stories with different takes on this concept.
