Edward could be an ordinary man living in a small town. He has always wanted a family of his own but couldn't find the right partner. So, he decides to adopt a child to start his own family unit.
He could be developed through his relationships. Maybe he has a best friend who doesn't understand his obsession with the famous football player at first. But as Edward tries to explain why he admires the player so much, it reveals more about his character, like his values of hard work and sportsmanship that he sees in the player.
The fanfiction might also explore a more supernatural or fictional aspect. For example, Edward could have some special ability that either helps him avoid getting the Spanish Influenza or gives him the power to heal those affected. This would add an interesting twist to the historical context of the epidemic.
A great part of Homunculus Edward fanfiction is the creativity in the plot twists. Writers can introduce unexpected elements. Like, what if Edward's alchemy was affected by a homunculus in a way that made him able to do things he never thought possible? This can lead to really engaging stories that keep readers on their toes.
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.
One of the main characters might be Alice. Her ability to see the future could be crucial in helping Edward navigate the political and dangerous situations in his role as king. Also, Jasper could be there. His experience in combat and control of emotions could be useful for Edward's rule. And then there's Rosalie, who might have her own opinions on how Edward should run the kingdom and could be a source of conflict or support depending on the story.
Edward would probably be very confused at first. He would try to understand why Bella would leave him for Rosalie. He might start to analyze all their past interactions, looking for signs that he missed. Eventually, he could become angry, not at Bella directly, but at the situation. He might also feel a sense of betrayal, not just from Bella but also from Rosalie in a way, since Rosalie is 'taking' Bella away from him.
It could be that there are external forces at play. Maybe there are other characters or some kind of dark secret in the fanfiction lore that forces Edward to leave Bella while she's pregnant. For example, there could be a threat from a rival group that says they'll harm Bella and the baby if Edward stays, and he thinks leaving will draw the danger away from them.
He could be devastated. Edward is deeply in love with Bella, so he might go into a state of depression. He may isolate himself from his vampire family and friends, constantly replaying in his mind what went wrong in their relationship.
