One idea could be exploring Lust's backstory before she became a Homunculus. Maybe she had a human life before and what led to her transformation. Another could be a fanfiction where Lust forms an unlikely alliance with a human alchemist. They could work together to achieve a common goal, like saving a town from a greater evil.
Their relationship could develop through mutual respect. If they are constantly thrown into situations where they have to rely on each other's skills. For example, in a battle against a powerful alchemist, Lust's combat abilities and Edward's alchemical knowledge could complement each other, leading to a grudging respect that might grow into a friendship of sorts.
Her character could be developed by exploring her moral compass. Since she is a Homunculus, she doesn't have the same moral framework as a human. But what if she starts to question her actions? Maybe she meets a young alchemist who makes her think about the consequences of her deeds.
One interesting plot idea could be that Edward and Lust are forced to team up against a common enemy. Maybe a new alchemic experiment gone wrong has created a powerful and dangerous being that threatens the world they know. Their combined knowledge of alchemy and Lust's unique abilities might make for an interesting dynamic as they struggle to defeat this foe.
Yes, it is. The manga has a perfect balance of action, drama, and philosophy. The themes explored are profound, and the character growth is very satisfying.
Some characters might be quite shocked or amused if they could read fanfiction about their own story. For example, Edward Elric would probably be very indignant at some of the out - of - character portrayals of himself. He's a proud alchemist and seeing himself depicted in a way that doesn't match his self - image would surely make him fume.
There probably are. Fanfiction writers often love to mash up different universes. In such a fanfic, Naruto could bring his chakra - based powers and blend them with the principles of alchemy from Fullmetal Alchemist. Maybe he'd use his Rasengan in a new way by incorporating alchemical transmutation circles. It would be a wild and creative concept.
