There might be a fanfiction where Edward gets a concussion while in a fight with an enemy. This could lead to him having strange dreams or hallucinations that are related to his past traumas and his journey to find the Philosopher's Stone. The concussion could be a trigger for him to re - evaluate some of his decisions and his relationship with alchemy.

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.
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.
