Fullmetal Alchemist Bradley Crossover Fanfic: What Are Some Interesting Plot Ideas?

One idea could be that Naruto characters somehow end up in the world of Fullmetal Alchemist. Maybe Naruto and Sasuke are chasing after a rogue ninja who uses some strange alchemy - like jutsu to open a portal to the other world. There, they have to learn about alchemy to find their way back home and in the process, they meet the Elric brothers and team up to fight against common enemies, like homunculi who are interested in the power of chakra.

To create a compelling Bradley in a crossover, you need to keep his core characteristics. His sense of duty and his military leadership skills should be emphasized. For example, if he crosses into a world of pirates, he could use his leadership to organize the pirates into a more efficient crew.

A plot could involve a crossover where Pride somehow gets trapped in a human body like the main characters in Fullmetal Alchemist. He has to adapt to human emotions and limitations while also dealing with the alchemists who are initially very suspicious of him. This would be a great opportunity to explore Pride's character in a different light and see how he copes with his new situation.

One plot idea could be an OC who is secretly searching for a way to reverse the effects of human transmutation without the use of the Philosopher's Stone. They could be an outcast in the alchemist community because of their unorthodox methods. Another idea is an OC who discovers a hidden alchemical society that has been operating in the shadows, with their own set of rules and secrets that could change the balance of power in the Fullmetal Alchemist world. A third plot idea could be an OC who has the ability to see the souls of those who have been affected by alchemy, and they use this ability to solve mysteries related to past alchemical experiments.

Another idea might be alternative endings. Fanfiction often plays with the concept of 'what if' things had gone differently. Maybe if Edward had not been able to regain his brother's body, how would he have coped and what new path would his life take?

Well, a great plot twist might be that the characters from Fairy Tail end up in the world of Fullmetal Alchemist and are mistaken for some sort of alchemical creations. They then have to prove that they are not and in the process, they discover that their magic has some strange effects on the alchemy in that world. For example, Gray's ice magic could freeze alchemical reactions in unexpected ways. Another plot twist could be that the Gate in Fullmetal Alchemist has a link to the Fairy Tail's Celestial Spirit World. So when someone tries to open the Gate, they accidentally open a portal to the Celestial Spirit World instead, and all kinds of chaos ensues as spirits and alchemists meet for the first time.

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.

One idea could be an OC who is a foreign alchemist with a unique form of alchemy based on their homeland's culture. For example, an alchemist from a desert region who uses sand-based alchemy. Another could be an OC that has a special connection to the Homunculi, not as an enemy but as someone trying to understand and redeem them. Maybe an OC that was experimented on by the same people who created the Homunculi and has some shared traits.

One interesting plot twist could be the discovery that the Philosopher's Stone in the Fullmetal Alchemist world has a connection to the chakra system in Naruto. Maybe it could be used to enhance or disrupt chakra flow in a way that no one expected. Another could be a character from Naruto, like Naruto himself, accidentally using alchemy due to some strange cross - world magic. This would completely change the dynamic as he tries to figure out this new power while still having his ninja abilities.

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.
