Some fanfictions might focus on the backstories of minor characters. For instance, a story about a Moogle who dreams of becoming a great wizard. He starts on a journey to find a powerful crystal that is said to grant magical powers. Along the way, he meets all sorts of characters from the World of Final Fantasy and has to overcome many challenges to reach his goal.
Some fanfictions focus on alternate endings. Maybe in one, the main antagonist in Dissidia Final Fantasy actually wins and the world is plunged into chaos. Then the remaining heroes have to find a way to reverse the situation, which can lead to a lot of creative plot twists and character development as they struggle against the new order.
He could fit in as a hero. Just like in his own world, he would fight against the evil forces in Final Fantasy. For instance, if there was a dark sorcerer threatening the land, Naruto would step up to protect the innocent. His ability to make friends easily would also help him gather allies from different parts of the Final Fantasy world.
One interesting storyline could be a redemption arc for Sephiroth. In this fanfic, Cloud might be the one to help him see the error of his ways. Maybe through their battles and interactions, Cloud starts to understand Sephiroth's tortured past and tries to guide him towards the light. This could involve them facing off against new threats together, with Sephiroth slowly learning to use his power for good instead of destruction.
One interesting storyline is about the restoration of Ishgard. It involves political intrigue, rebuilding a war - torn nation, and mending relations between different factions. There are also stories about the beast tribes and how they can be befriended rather than just fought, which shows a different side of the game's ecology.
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.
He might use his ninja skills in a unique way. For example, his Shadow Clone Jutsu could be used for various tasks like exploring dungeons simultaneously or confusing the enemies in the Final Fantasy world which often have complex battle systems. Also, his Rasengan could be a powerful attack against the magical creatures there.
One interesting story could be about Tidus exploring new areas of Spira that were not shown in the original game. Maybe he discovers hidden temples with unique aeons.
One interesting concept could be exploring the backstories of minor characters. For example, delving into the past of a random villager who might have a hidden connection to the main plot. Another concept could be alternate endings, like if the main character made a different choice at a crucial moment. Also, fanfiction might explore the relationships between characters in more depth, such as a deeper friendship or a romantic relationship that was only hinted at in the game.
One interesting story could be about the characters' backstories that were not fully explored in the game. For example, a fanfiction might delve deeper into Basch's life before the events of the game, his training, and his relationships. It could show how his past experiences shaped him into the character we see in the game.
One interesting aspect is the exploration of different character relationships. In Final Fantasy 14 fanfiction, writers can delve deeper into the bonds between the in - game characters. For example, they might explore the friendship between a Warrior of Light and their Scion comrades in more detail, showing their shared adventures and how they support each other. Another aspect is the expansion of the game's lore. Fanfiction can introduce new ideas or interpretations of the existing lore, like creating backstories for minor characters or exploring different timelines within the Final Fantasy 14 universe.
