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.
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.
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.
One great Edward Elric in DC fanfiction is 'The Alchemist in Gotham'. In this story, Edward's alchemical skills bring a unique dynamic to the DC universe. His no - nonsense attitude and determination to do what's right fit well with the morally complex world of DC.
Perhaps Edward and Urahara would have an interesting dynamic in combat. Edward's quick - thinking and ability to transmute objects on the fly could be a great complement to Urahara's zanpakuto skills and his use of various spiritual items. They could learn from each other's fighting styles and develop new techniques together. Urahara might also introduce Edward to some of the other characters in the Bleach universe, like Orihime and Chad, and Edward could share stories about his friends in Amestris.
One great 'Angel Edward Elric' fanfiction is 'The Celestial Alchemist'. It has a really interesting plot where Edward discovers his angelic powers and has to use them to save his world from a dark force. The character development is well - done and it stays true to the original 'Fullmetal Alchemist' vibe.
Edward Elric has a more straightforward personality. He wears his emotions on his sleeve. When he's angry, you know it, and when he's happy, he shows it. He's also very sarcastic at times. Edward Cullen is a bit more complex. He's got that mysterious allure because of his vampire status. He's not as open with his emotions as Elric. Cullen is more introspective, always thinking about the consequences of his actions, especially since his actions can have a big impact on the humans around him.
At first, Edward might be a bit resistant to Roy's attempts at adoption. But as time goes on, Roy shows his care and concern for Edward. He helps Edward with his problems, like dealing with the homunculi or his own self - doubt. Edward then starts to rely on Roy more, and their relationship deepens into a strong bond of family - like love.
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.
One common theme is the exploration of innocence. When Edward is deaged, he loses some of his worldly knowledge and cynicism, and the fanfics often explore how he rediscovers the world with a sense of wonder. For example, he might be fascinated by simple things like flowers or the sound of rain again.
