One great 'Final Fantasy Sephiroth Crossover Fanfiction' is 'Sephiroth in Another World'. It's really interesting as it takes Sephiroth and throws him into a modern - day Earth setting. The way the author describes his confusion and then his gradual adaptation is quite engaging.
A good 'Final Fantasy Sephiroth Crossover Fanfiction' should have a believable crossover concept. For example, if he crosses into a different universe, the rules of that universe should be well - defined and Sephiroth's presence should make sense within it.
One idea could be a crossover between Final Fantasy VII and Final Fantasy X. Imagine Cloud and Tidus teaming up to fight a new powerful enemy. Another could be a crossover with a non - Final Fantasy franchise like Pokemon. Picture Squall trying to catch Pokemon in the world of Final Fantasy VIII.
One common theme is self - discovery. Auron often finds himself in new and strange situations in crossovers, which makes him question who he is outside of his original Final Fantasy world.
The crossover could be conceptualized by having the female Harry Potter character be a key figure in a prophecy in the Final Fantasy world. Just like in the Potterverse, she might be the 'chosen one' to defeat a great evil. Her unique skills from the Harry Potter world, such as her ability to fly on a broomstick, could be translated into something extraordinary in Final Fantasy. She could use her broomstick to quickly traverse the vast landscapes of the Final Fantasy world, much like a Chocobo but with a magical, Potter - like twist.
First, choose the Final Fantasy games or elements you want to cross over. Then, think about the main characters from those and how they would interact. For example, if it's a crossover between FFIX and FFVI, consider how Zidane and Terra would meet.
A 'Final Fantasy VIII Crossover Fanfiction' could involve crossing it with the world of 'Alice in Wonderland'. Rinoa could be like Alice, falling into a strange world where everything is topsy - turvy. The Heartless from Kingdom Hearts could also be added to the mix in a crossover. The characters of Final Fantasy VIII would have to fight these new enemies, with Squall taking on the role of a keyblade wielder in this strange new world.
One interesting storyline could be the combination of Naruto's ninjutsu with Final Fantasy 7's materia system. Imagine Naruto using materia - enhanced jutsus. Another could be Cloud and Naruto teaming up to fight a common enemy like Sephiroth and Madara combined. It would be epic to see their different fighting styles blend.
One idea could be a crossover with another popular RPG like Dragon Quest. The characters from World of Final Fantasy could end up in the world of Dragon Quest, facing new enemies and having to adapt to different magic systems. For example, the mirages in World of Final Fantasy might interact in strange ways with the slimes in Dragon Quest.
Lann and Reynn are obvious choices. They are the main characters in World of Final Fantasy and can serve as the link between different crossover worlds. Their ability to capture and use mirages makes them versatile in different settings.
