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.
There are fma scar crossover fanfictions that explore Scar's backstory in relation to the new crossover element. Maybe in a crossover with a steampunk - themed world, Scar has to adapt his combat and alchemy to the new technology and culture. It can be really interesting to see how his character develops in such a different setting.
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 Scar Crossover Fanfiction could be one where Scar from 'The Lion King' crosses over into a fantasy world like Middle - earth. He might interact with characters like Aragorn, and the story could explore how his villainous nature clashes or finds common ground in this new world.
Some fma crossovers involve characters from DC Comics. Picture Batman or Superman in the world of FMA, dealing with the concept of equivalent exchange and the political intrigue in that world. It can lead to some really unique storylines and character interactions.
You should also research both Fullmetal Alchemist and the other source material thoroughly. This helps in creating a more believable and engaging crossover. For instance, if you're crossing Scar with a character from a high - fantasy world, understanding the magic systems in both worlds will allow you to write better interactions. Don't be afraid to put your own spin on things and create unique plot twists.
One idea could be to have the characters from 'Fullmetal Alchemist' (FMA) end up in the 'Ouran High School Host Club' (OHSHC) universe. For example, Edward and Alphonse could enroll in Ouran High School. Edward's short temper and Alphonse's gentle nature would create interesting interactions with the host club members. They could get involved in the club's activities, like the commoner's day event, and bring their alchemical knowledge into this new world.
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.
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.
The key elements are the Ishvalan massacre, the role of State Alchemists, and Scar's revenge. His people, the Ishvalans, were brutally killed, and the Alchemists were involved. So, he seeks revenge on them.
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.
Scar in FMA has a tragic back story. He's from the Ishvalan race. His people were massacred in a brutal war. The State Alchemists were used in this war, and Scar witnessed the destruction of his homeland and the loss of his loved ones. This led him on a path of revenge against the Alchemists.
