What are some interesting plot ideas for Final Fantasy 13 fanfiction?

A great plot idea could be an OC that is a former villain who has seen the error of their ways. They now try to redeem themselves by helping the heroes. For example, they might have insider knowledge about the plans of the main antagonist. Another plot could be an OC who is a healer with a very unorthodox method of healing. They are initially scorned by the traditional healers but prove their worth during a major battle. Also, an OC who is a thief with a heart of gold, stealing from the corrupt nobles to help the poor and then getting involved in the main story's quest could make for an exciting fanfiction.

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.

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.

One idea could be a male self - insert who has the power to control time. He uses this power to prevent certain tragic events in the Final Fantasy 7 world, like the destruction of Aerith. Another plot could involve the male SI being a master of a new type of materia that no one has seen before, which attracts the attention of both Shinra and Avalanche. He has to decide which side to ally with or if he should remain neutral.

Maybe the Philosopher's Stone in Harry Potter has some connection to a powerful crystal in Final Fantasy. Voldemort wants to use it to gain ultimate power, and the heroes from both universes have to come together to protect it. For example, Cloud Strife could join forces with Harry and his friends. The Hogwarts houses could be compared to the different classes in Final Fantasy, like Gryffindor being similar to the Warriors in Final Fantasy.

Well, a really cool plot could be that the Mass Effect Relay network somehow gets connected to the Crystal Materia in Final Fantasy. This causes chaos as both universes start to blend. Characters from both sides have to figure out how to separate the two worlds again. Along the way, they discover that there are ancient forces at work in both universes that are related. Tali could use her engineering skills to help repair some of the damaged Crystal Materia, while Squall could teach her some sword - fighting techniques from his Gunblade.

Maybe an OC who is a former Shinra scientist but turned against them. They have knowledge of secret projects that tie into the events of Crisis Core. They team up with Zack to expose Shinra's wrongdoings, adding a new layer of mystery to the story.

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 main characters in more depth. For example, Noctis' training as a prince and his relationship with his father before the events of the game. Another could be a fanfiction set in an alternate universe where the Astrals have different roles or relationships with the humans. Maybe a story where Noctis and his friends have to face a new, unexpected threat that wasn't in the original game.

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.
