The plot could involve the OC being a alchemist on a quest for a powerful alchemy item. Greed, sensing an opportunity for himself, joins the OC. Along the way, they encounter various enemies and obstacles. For instance, they might have to face off against other homunculi who don't want Greed interfering in their plans. The relationship between Greed and the OC could start off as a simple partnership but evolve into a deep friendship or more as they rely on each other to survive.
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.
If you're writing a Fullmetal Alchemist Brotherhood OC fanfiction, research is key. Dive deep into the lore of the series. Know about the different types of alchemy, like the forbidden alchemy. Your OC might be tempted by the power of forbidden alchemy, which could lead to an interesting plot. Another thing to consider is the cultural aspects. For instance, the Xingese culture plays a part in the story. Maybe your OC has some connection to Xing. You can also look at the power dynamics between the military and the civilians. Is your OC a part of the military? If so, what are their views on the military's actions? All these elements will add depth to your OC and make your fanfiction more immersive.
One great example could be a fanfiction where the OC is a gamer who gets transported into the Fullmetal Alchemist world. They use their gaming knowledge to navigate the complex alchemy system. For instance, they might approach transmutations like they would in-game quests, looking for the right ingredients and following specific 'rules' they've learned from games. This could lead to unique interactions with the existing characters, like explaining modern gaming concepts to Edward and Alphonse.
One common theme is redemption. The original Fullmetal Alchemist has a strong sense of characters dealing with the consequences of their actions. In OC reincarnation fanfictions, new characters often have to face their past mistakes or the sins of their predecessors. Another theme is self - discovery. The OCs are in a new world with new identities, and they have to figure out who they are in relation to the existing characters and the alchemical world. Also, friendship and loyalty play a big role. Just like in the original series, the OCs form bonds with the characters from Fullmetal Alchemist, and these relationships are tested through various challenges.
To create a compelling male OC in Fullmetal Alchemist fanfiction, first, consider the world's rules. Alchemy has strict laws, so your OC's abilities should align with it. For example, if your OC is a State Alchemist, his specialty should be unique yet plausible. Second, give him a strong backstory. Maybe he has a tragic past like losing a family member in the Ishvalan War, which drives his actions. Third, develop his personality. He could be a bit of a rebel against the military's strict regime but still have a moral compass.
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 are many fanfictions where Ed is portrayed as a girl. Fanfiction writers like to play with the existing characters in new ways. By making Ed a girl, they can introduce new themes and perspectives. For example, it could change how the story deals with gender roles in the world of Fullmetal Alchemist. Also, it can create new emotional arcs for the character, as a female Ed might face different challenges and experiences compared to the male version in the original story.
One great fanfiction could be about Izumi's backstory before she became an alchemist. It might explore her early training days and the challenges she faced. For example, a story could focus on how she overcame the difficulties of learning complex alchemical theories without proper guidance at first.
