Well, Edward Elric has alchemy on his side. He can transmute elements, create weapons out of thin air, and has great combat skills from his battles in the Fullmetal Alchemist world. On the other hand, Edward Cullen has superhuman strength, speed, and senses as a vampire. But I think Edward Elric would win. His alchemy gives him more versatility in combat. He could transmute the ground beneath Edward Cullen to trap him or create barriers to defend against Cullen's attacks.
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.
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.
I would recommend 'A New Beginning for Bella and Edward'. This fanfic takes their story in a different direction after the events in the original series. It shows how they handle new challenges together and the growth of their love in the face of those difficulties. There are some really beautiful and heart - warming moments in it.
They are popular because their relationship is so unique. Edward is Renesmee's father in a very unconventional vampire - half - vampire family dynamic. Writers like to explore this complex bond.
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.
