One idea could be exploring the backstories of the minor characters in more detail. For example, the merchants in the game might have their own adventures before arriving in the main cities. Another could be a 'what if' scenario, like what if Ashe had made different decisions during her quest for the throne. A third idea is to focus on the relationship between the characters outside of the main storyline, such as how Basch and Gabranth interacted when they were children.
Well, you could write a fan fiction about the magic system in Final Fantasy 12. Maybe there are hidden aspects of magic that the main characters haven't discovered yet. Or you could create a story that takes place in a different part of the game world that we don't get to see much of in the original game. Also, a fan fiction about the monsters in the game could be cool. You could give them personalities and motives, like a story from the perspective of a huntable monster trying to avoid being hunted.
Some interesting ideas for Final Fantasy 12 fan fiction include a time - travel story. Imagine if a character from the present went back in time to change a crucial event in Ivalice's history. It could completely change the course of the game's events. Another idea is to write a story centered around the airships. The airships are a big part of the game's world, and there could be many untold stories about their construction, the people who fly them, and the places they've been. You could also do a fan fiction that focuses on the cultural differences between the different races in Ivalice, like how they interact, trade, or even fight with each other.
You could write a fan fiction about the magic in Final Fantasy XVI. Maybe create a story about a new type of magic that is discovered in the world of Valisthea. It could be a magic that has both great power and a dangerous cost. Or, you could write about a character from the game who has to master a difficult form of magic and the trials they go through. Also, a fan fiction about how the different kingdoms in the game interact with each other through the use of magic would be interesting.
One interesting concept could be exploring the backstories of minor characters. For example, the guards in Baron Castle might have their own motives and dreams that are not shown in the original game. Another concept could be alternate endings. Maybe Cecil and Rosa could have a different kind of ending where they choose different paths in life.
One idea could be exploring the backstories of the minor characters. For example, the SeeD trainees who don't get much spotlight in the game. Another could be a 'what if' scenario, like what if Squall and Rinoa didn't end up together? It could also be interesting to write about the world of Final Fantasy 8 from the perspective of an ordinary citizen living in one of the cities, dealing with the sorceress wars and the chaos that ensues.
There could be a fan fiction where Aerith survives the events that originally led to her death. Cloud then has to protect her from new threats while also coming to terms with his own feelings for her in a more peaceful setting. They might travel across the world of Final Fantasy 7, encountering new friends and foes, and building a life together that was previously thought impossible.
A great Naruto Final Fantasy fanfiction idea is to combine the magic systems. In this story, shinobi could learn to use Final Fantasy - style magic, like black magic for offensive spells and white magic for healing. Or perhaps a plot where the Akatsuki is after a powerful crystal from the Final Fantasy world that could grant them ultimate power. Also, a fanfic about a character from Naruto traveling through different worlds of Final Fantasy, facing the challenges and enemies in each world.
One idea could be to create an OC who is a mage from a long - lost tribe in Ivalice. They could have unique spells that are based on ancient tribal magic. Another idea is an OC that is a sky pirate with a mysterious past, perhaps related to the great airships of the game. Or an OC that is a knight trying to restore an old code of honor in a time of political unrest in the game's world.
One idea could be exploring the backstory of the main character's family in more detail. Maybe there were secrets or hidden powers within the family that were never fully explored in the game.
A crossover with the Star Wars universe could also be exciting. Imagine the characters of Final Fantasy 13 in a galaxy far, far away. Snow could be like a Jedi, using his strong will and combat skills, while Fang might be more of a bounty hunter type, roaming the galaxy in search of valuable prey.
One idea could be a crossover with the 'Harry Potter' universe. Squall could be a wizard, and his gunblade could be enchanted. Another could be a crossover with 'Star Wars', where the characters from Final Fantasy 8 are in the middle of the galactic conflict. Maybe Laguna could be a Jedi - like figure.
One idea could be exploring the backstories of the minor characters in more depth. For example, the story of the civilians in Cocoon who were affected by the events. Another could be a what - if scenario, like what if Lightning had made different choices at certain key moments. And a third could be focusing on the relationship between Fang and Vanille before they became l'Cie.
