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.
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.
Edward's intelligence. He is a brilliant alchemist. A fanfic could explore how he shares his knowledge with the reader, perhaps teaching the reader alchemy. This could lead to some really interesting adventures where they use alchemy to solve problems in their world. And the reader could also bring out a different side of Edward as he gets closer to someone who is not as experienced in alchemy as he is.
Some fanfics to check out are 'Brotherly Love in Amestris'. This one takes a more in - depth look at their relationship within the context of the Amestris world. It shows how their love for each other is a driving force. 'The Elric Brothers' Growth' is also a good read. It follows their development as individuals and as a duo. It shows how they grow together and learn from each other. Also, 'Edward and Alphonse: A Bond Beyond Alchemy' is interesting as it explores their relationship outside of the typical alchemy - related events.
You can start by looking on fanfiction.net. It has a large collection of fanfics from various fandoms, including Fullmetal Alchemist where Edward and Alphonse are from. Archive of Our Own (AO3) is also a great place. It has a well - organized tagging system that makes it easy to find specific fanfics about the Elric brothers.
One great piece of Edward Elric x Alphonse Elric fan fiction is 'The Bond Beyond Alchemy'. It delves deep into their relationship, exploring how they support each other through different trials. Another is 'Two Souls, One Journey' which focuses on their adventures together from a more emotional perspective, highlighting their unbreakable bond.
Well, the theme of sacrifice is quite common. Edward and Alphonse have both sacrificed a great deal for each other in the original series, and fan fictions expand on this idea. Also, the exploration of their alchemy powers in relation to their relationship is a frequent theme. How their abilities are intertwined and how they use them to help each other is often explored. And of course, the theme of family, not just as brothers but also in a broader sense, like how they fit into the world as family members.
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.
