There's also 'Homunculus in Another Realm'. In this fanfic, the homunculi are sent to a parallel universe. It has an interesting plot where they interact with new characters and face different challenges than in the original FMA world. The author does a great job of portraying their personalities in this new setting.
Well, 'Homunculus Crossover: The Unexpected Alliance' is a great one too. Here, the homunculi end up in a world full of superheroes. The story is filled with action as they form unexpected alliances and rivalries. It's really exciting to see how the homunculus' powers interact with the superpowers in this new world.
One common theme is identity. Since the homunculi are in a new crossover world, they often question who they are and their place in this new setting. For example, in many crossovers, they might compare themselves to the new characters they meet.
I've also heard about 'Lust and the Elric Brothers' Crossover'. This fanfiction delves into how Lust's presence could change the dynamics between Edward and Alphonse Elric. It has some exciting action scenes as well as some emotional moments that are really well - written.
For a crossover with a post - apocalyptic world, characters like Mad Max could be involved. He might see the homunculi as either allies or threats in the harsh new world. In a crossover with a cyberpunk world, characters like Neo from 'The Matrix' could be interesting. The homunculi could be part of the complex digital and physical world that Neo navigates, and he could help them understand the true nature of their existence in this new, high - tech world.
First, know both universes well. For an fma crossover, you need to understand the rules of alchemy in FMA and the characteristics of the other universe you're crossing it with. For example, if it's a Star Wars crossover, know about the Force and lightsabers as well as alchemy.
A lesser - known but very creative fma envy crossover fanfiction is the one that combines the world of FMA with a steampunk - themed universe. Envy has to adapt to the new rules and technology in this world, and the story does an excellent job of showing this transformation.
One great fma scar crossover fanfiction could be where Scar teams up with a character from another universe to fight a common enemy. For example, a crossover with a character from Naruto. Scar's unique alchemy skills combined with the ninja's jutsu would make for an exciting plot.
I'm not sure about a specific one off the top of my head. But you can try searching on fanfiction.net or Archive of Our Own. They usually have a wide range of crossover fanfictions.
Often, these fanfictions blend the dark and complex world of Fullmetal Alchemist with the idea of 'lust' which could be in terms of a character's desires or a new, alluring force in the story. They might also explore different character relationships and how 'lust' can either strengthen or disrupt them.
To write a good fma crossover fanfic, start by choosing the right crossover. It should be something that has potential for interesting interactions. For instance, if it's an FMA and Bleach crossover, think about how alchemy and soul reaper powers could interact. Research both fandoms thoroughly. Look at their cultures, technologies, and power systems. When writing the story, focus on the emotions of the characters. Show how they react to this new and strange crossover world. Use vivid descriptions to bring both universes to life in the fanfic. And don't forget to proofread and get feedback from other fans.
First, know the characters well. Understand Greed's personality, his desires, and his powers in FMA. Then, research the other fandom you want to crossover with. Next, create a unique and engaging plot that combines elements from both worlds in a seamless way. For example, if it's a crossover with a fantasy world, think about how Greed's alchemical nature would interact with magic. Don't forget to develop good character relationships and let the story flow naturally.
