One interesting fanfiction could be about Edward and Hohenheim going on a journey together to uncover a long - lost alchemical secret. They might face various challenges along the way and bond over their shared knowledge of alchemy.
A fanfiction might focus on a parallel universe where Edward and Hohenheim are just ordinary people without alchemical abilities. In this story, they have to build their relationship from scratch, dealing with normal family issues like communication problems and differences in values. It shows how, even without the extraordinary element of alchemy, their connection as father and son can still be deep and meaningful.
There could be a fanfiction where Hohenheim, after years of absence, tries to reconnect with Edward. It delves into their complex relationship, with Edward initially being resentful but gradually coming to understand his father's past and the reasons for his actions. This could involve flashbacks to Hohenheim's life before Edward was born and how it all ties into the current situation. It might also explore how their alchemical powers interact in different scenarios, like when they are faced with a powerful enemy or when trying to heal someone. Through their interactions, they both grow as characters and learn more about themselves and each other.
Some fanfictions might center around Van Hohenheim's connection to the homunculi. For example, a story could explore how he feels about being their creator in a more emotional and complex way. It could also be a fanfiction where he teams up with Edward and Alphonse to fight against a new threat that is related to his past actions. This would give a chance to see his character develop further in a different context, and show his loyalty to his sons in a more extreme situation.
I'm not sure who the absolute best is, but there are some authors who are well - known in the fanfiction community. Some of the more popular ones might be those who have a deep understanding of the 'Fullmetal Alchemist' universe. They can really capture the essence of Edward and Hohenheim's characters and their relationship.
You can start by looking on popular fanfiction websites like Archive of Our Own (AO3). It has a large collection of fanfictions across various fandoms, and you're likely to find some great Edward Elric Van Hohenheim ones there. Another option is FanFiction.net, which has been around for a long time and has a lot of content. Just search for his name in the search bar on these sites.
Some fanfictions might explore the concept of Edward being protected by an angel. The angel could be a new character or perhaps an existing character from the series in an angelic form. This protection could be due to a prophecy or because Edward has some special role to play in the grand scheme of things related to the angelic realm.
One interesting story could be where Edward uses his alchemy skills in a unique way related to milk. Maybe he discovers a new alchemical property of milk that helps him in his quest. For example, it could be a story where he uses milk to create a special potion that gives him temporary enhanced strength.
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.
One interesting fanfiction could be where Naruto and Edward Elric team up to fight a common enemy that has elements from both their worlds, like a chimera made of shadow clones and alchemy - based creatures. They'd use Naruto's ninja skills and Edward's alchemy in unique combinations.
Another plotline might involve Edward reuniting with his old friends and family. There could be emotional reunions and then they all team up to face a new, greater threat together. They might have to overcome past misunderstandings and grow stronger as a group. For example, Edward could find that his brother Alphonse has developed in unexpected ways while he was away, and they have to readjust to each other.
In this fanfiction, her role as an alchemist might be perceived differently. As a girl, she might face more discrimination in the male - dominated field of alchemy. This could lead to stories of her having to prove herself more often and in different ways than in the original story.
The challenges she faces can also be different. In the original story, Edward had his own set of difficulties as a male alchemist. As a female, she might face additional discrimination or different expectations in the world of alchemy. Fanfictions can explore how she overcomes these new challenges while still trying to achieve her goals like getting their bodies back (if following the main plot of the original story).
