Fanfiction ideas combining Naruto and Final Fantasy 13
A possible fanfiction could involve a fusion of the two worlds' power systems. The characters from both Naruto and Final Fantasy 13 could exchange knowledge about their abilities. For instance, the summonings in Naruto could be related to the Eidolons in Final Fantasy 13, and they could find ways to combine their powers for a greater good.
Fanfiction Ideas Combining Naruto and Final Fantasy 15
One idea could be to have Naruto characters in the world of Final Fantasy 15. For example, Naruto could be a guest in Noctis' group. He could use his ninja skills like shadow clones to help in battles against the daemons in Final Fantasy 15. His chakra could be seen as a new form of magic in that world.
Fanfiction ideas combining Naruto and Final Fantasy 10
One idea could be to have Naruto characters in the world of Final Fantasy 10. For example, Naruto could be a Blitzball player, using his speed and agility. Sakura could be a healer, like a White Mage in Final Fantasy 10. They could be on a quest to stop Seymour from achieving his evil plans, with Naruto's Rasengan being a powerful attack against the fiends in Spira.
Fanfiction ideas combining RWBY and Final Fantasy 15
One idea could be to have the characters from RWBY end up in the world of Final Fantasy 15. For example, Ruby could meet Noctis and they could team up to fight some common enemy. Ruby's speed and scythe - wielding skills could be a great addition to Noctis' combat style.
Fanfiction ideas combining Final Fantasy and Lululemon
Perhaps a Final Fantasy character gets transported to our modern world and has to work at a Lululemon store to earn money for their journey back home. They learn about modern fashion and the concept of athleisure, and there could be some comical moments as they try to adapt to this new environment.
Fanfiction ideas combining Harry Potter and Final Fantasy's Sephiroth
One idea could be a crossover where Sephiroth somehow ends up in the wizarding world of Harry Potter. Maybe he's a dark force that Voldemort tries to use for his own gain, but Sephiroth has his own agenda. He could use his powerful magic, which is different from the magic in the Potterverse, to create chaos.
Fanfiction ideas combining Naruto and Gandalf
Another concept is that Naruto is sent to Middle - earth. There, he could use his ninja skills and chakra powers. He and Gandalf could team up to fight Sauron. Naruto's ability to make friends and inspire others would be really useful in uniting the different races of Middle - earth against the common enemy.
Fanfiction ideas combining Naruto and Needless
One idea could be a crossover where Naruto characters gain the abilities of Needless characters. For example, Naruto could get the power of Adam Blade's regeneration. It would be interesting to see how he uses it in battle, especially against tough foes like Pain or Madara.
Fanfiction Ideas Combining Naruto and Transformers
Another fanfiction concept could be that a few ninjas, including Naruto, are given the ability to transform into mini - Transformers. They could use these new forms to gain an edge in battle, combining their ninja skills with the advanced weaponry and abilities of the Transformers. This would create a whole new dynamic in the Naruto battles and introduce some really interesting fight scenes.
Fanfiction Ideas Combining Naruto and Euphemia
Another concept is that Euphemia discovers a strange portal and steps through it, ending up in the Naruto universe. There, she befriends Naruto and his friends. She could use her diplomatic skills to try and bring peace between the warring ninja clans, while also learning some ninja techniques herself.
Fanfiction Ideas Combining Naruto and Bloodborne
One idea could be to have Naruto enter the world of Bloodborne. Maybe he is on a mission and accidentally gets transported there. He would have to deal with the dark and dangerous creatures using his ninja skills. His chakra could be an interesting element in this world, perhaps being mistaken for some sort of otherworldly power by the inhabitants of Bloodborne.
