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.
The allure lies in the fact that we can see different sides of Rosalie and Edward. In fanfiction, we might see a more vulnerable Edward or a more forgiving Rosalie. It gives fans the chance to rewrite their relationship in a way that satisfies their own desires for the characters.
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.
Edward might be initially shocked and heartbroken. He has been in love with Bella for a long time, so her leaving for Jasper would be a huge blow. He could become withdrawn and moody, brooding over what went wrong.
His family members are quite popular. Maybe a sister or a brother who has a different view on the family wealth. They can bring in family drama. Also, the love interest is very important. It could be someone he meets by chance, like a struggling artist or a young journalist who is intrigued by him and his world.
There could be a prison guard who takes an interest in Edward's case. This guard might be sympathetic and start to help Edward in small ways, like getting him access to a lawyer or better living conditions in jail.
It often starts with attraction. Edward is drawn to Bella's unique scent and her differentness. Bella, on the other hand, is intrigued by Edward's mysterious nature.
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.
Perhaps they are characters in a modern - day wizarding world where they are both part of a secret magic society. Edward could be a powerful wizard from an old family who feels threatened by Harry's new - found powers. So, he decides to break Harry's heart to assert his dominance.
An enchantress could also be a love interest. She might offer Edward a solution to his heir problem through magic, but in return, she wants something from him. Their relationship could be a complex one of power, love, and mystery. Edward would have to navigate through her world of magic while also dealing with his own desires for an heir and the future of his kingdom.
