A great idea for 'ff13 crossover fanfiction' is to cross it with a superhero universe like the Marvel Cinematic Universe. The FF13 characters could team up with superheroes or even face off against some villains. It would be exciting to see how their powers compare. Another option could be a crossover with a horror - themed world like 'Silent Hill'. The dark and mysterious atmosphere of Silent Hill could add a new level of spookiness to the FF13 story. You could also consider a crossover with a post - apocalyptic world like 'The Walking Dead'. The FF13 characters would have to adapt to a world full of zombies and survival challenges.
One idea could be a crossover with another popular RPG like 'Dragon Age'. Imagine the characters from FF13 in the world of Thedas, dealing with the different races and magic systems there. Another idea is a crossover with a sci - fi universe like 'Mass Effect'. The technology and alien species in that universe would create a really unique setting for the FF13 characters. Or perhaps a crossover with a classic fantasy like 'The Lord of the Rings'. The FF13 characters could interact with hobbits, elves, and dwarves, which would be quite a sight.
Well, for 'ff13 crossover fanfiction', you could do a crossover with an anime. For example, 'Fullmetal Alchemist'. The alchemical concepts in that anime could blend interestingly with the magic and technology in FF13. Also, a crossover with 'Naruto' would be cool. The ninja abilities and the shinobi world could contrast and interact with the world of FF13 in a lot of ways. And a crossover with 'One Piece' might be really fun. Picture the FF13 characters on the Grand Line, dealing with pirates and the strange islands.
A FF14 crossover fanfiction could involve crossing over with the 'Harry Potter' universe. The mages in FF14 could attend Hogwarts and learn different forms of magic. Or, a crossover with the 'Star Wars' universe. The Jedi and Sith powers could be compared and contrasted with FF14's dark and light magic. Also, a crossover with the 'Pokémon' world. The players in FF14 could capture and train Pokémon alongside their normal adventures.
A cool 'ff7 crossover fanfiction' idea could be to cross it with the 'Star Wars' universe. Picture Sephiroth as a Sith Lord, with his powerful abilities and dark charisma. He could face off against Jedi Knights. Or perhaps Aerith could befriend some of the more force - sensitive characters in the Star Wars universe. Another option is to crossover with the 'Mass Effect' series. The technology in Mass Effect could be an interesting contrast to the more magic - based elements in FF7. Characters like Tifa could interact with the alien species in Mass Effect.
Another interesting concept is to have the chakra system from Naruto integrated into the FF7 universe. Maybe the materia could be enhanced by chakra, or characters could learn to use jutsu instead of magic. For instance, Aerith could learn some healing jutsu to add to her abilities.
One idea could be exploring the backstory of an original character (OC) within the world of FF7. For example, an OC who is a SOLDIER trainee but has a secret connection to the Ancients. Another could be an OC who is a merchant in Midgar, dealing with the various gangs and Shinra's influence. And also, an OC who is a researcher studying the effects of Mako on the planet.
One idea could be creating an OC who is a powerful mage from a hidden village. They could join the main characters on their journey and use their unique magic to help in battles. For example, magic that can manipulate time briefly to give an advantage in combat.
One idea could be Naruto being summoned into the world of FF14. He might initially be confused but quickly adapt his ninja skills to the new environment. For example, his ability to use chakra could be translated into a unique form of magic in FF14.
One interesting idea could be changing the outcome of key battles. For example, if a character travels back in time, they might be able to prevent a certain loss in a fight, which could then change the entire course of the story. Another idea could be related to relationships. A character might go back in time to fix a broken relationship or to start a relationship earlier than it originally happened in the ff8 universe.
One interesting idea could be a crossover with "Moana". Elsa's ice powers and Moana's connection to the ocean could create a really cool dynamic. Maybe Elsa accidentally freezes part of Moana's ocean and they have to work together to fix it. Another could be with "Tangled". Rapunzel's long hair and her adventurous spirit combined with Elsa and Anna's journey in Frozen 2 would be exciting. Rapunzel could use her hair to help them climb mountains or cross chasms. A third idea is a crossover with "Beauty and the Beast". Belle's love for books and knowledge could help Elsa understand more about her powers and the history of magic in the Frozen world.
One idea could be that the OC is a powerful mage from a far - off land who crosses paths with Noctis during his journey. They initially clash due to different beliefs but gradually come to understand and support each other. Another could be the OC being a commoner who saves Noctis from a dangerous situation, and Noctis feels indebted to her and they form an unlikely bond.
A Rambo crossover fanfiction could involve him crossing over into the Star Wars universe. Rambo's guerilla warfare tactics could be interesting in a galaxy far, far away. Maybe he helps the Rebel Alliance in a ground - based battle against the Empire. Or a crossover with the Predator series. Rambo would be a worthy opponent for the Predator, and the fight between them in the jungle could be epic. Also, a Rambo and John Wick crossover would be intense, two highly skilled fighters on the same side or perhaps initially at odds.
