Well, you could create a fanfiction where a Stark character travels to the Naruto universe. Let's say Arya Stark ends up in the Hidden Leaf Village. She could learn their ways of combat and incorporate her own skills. Meanwhile, Naruto characters might be intrigued by her tenacity and her different style of fighting. And in a more complex scenario, some of the Game of Thrones politics could seep into the Naruto world, causing new power dynamics among the ninja clans.
One way to combine them creatively could be to have Naruto characters in the world of Game of Thrones with the Stark family. For example, Naruto's ninja skills could be used in the political intrigue of Westeros. He could form an alliance with the Starks, perhaps teaching them some of his unique jutsu to help in battles against their enemies like the Lannisters. His ability to move quickly and stealthily could be a great asset in the land of Westeros where information and surprise attacks are crucial.
One way to combine them creatively could be to have the bending abilities from Avatar in the world of Game of Thrones. For example, a waterbender could use their skills in the battles near the sea or a river in Westeros. They could freeze the water to create barriers or use water whips against the enemy. Another idea is to have the political intrigue of Game of Thrones play out among the different nations in the Avatar world. The power struggles between the Fire Nation, Earth Kingdom, Water Tribes and Air Nomads could be intensified with the addition of the complex political strategies seen in Game of Thrones.
Well, in a Naruto - Game of Thrones fanfiction, you could have the Sharingan (from Naruto) be a rare and mysterious power in the Game of Thrones world. Maybe a character discovers they have this power and it's seen as a sign from the gods. And then, just like in Naruto, there are different levels of power associated with it. This could lead to new alliances being formed as houses try to either control or protect the person with the Sharingan.
Another aspect could be the plot. A fanfiction could revolve around Naruto being sent to the Norse realm due to some kind of dimensional rift. There, he might encounter Loki and Thor. He could form an alliance with Thor to fight against a common enemy, using his ninja tactics along with Thor's hammer and lightning powers.
One way to combine them creatively could be to create a crossover universe. For example, Naruto's world of ninjas could intersect with Supergirl's world of superheroes. Lemon could be a new character introduced in this combined world, perhaps with a special power related to nature like Naruto's connection to nature through chakra but with a citrus - themed twist. She could team up with Naruto and Supergirl to fight a common enemy that threatens both their worlds.
They can be blended through shared themes. Both have elements of power struggles, loyalty, and survival. In fanfiction, you could explore how a character like Jon Snow from Game of Thrones would handle the political intrigue among the Vikings. Or how a Viking leader would react to the magic and mythical creatures in the Game of Thrones world. You could also focus on the family dynamics in both and create a story where a family from one universe has to adapt to the other's family structure.
One way to combine them is through crossovers. Imagine Naruto characters having the Force in the Star Wars universe. They could use their ninja skills along with Jedi powers. For example, Naruto's clones could be used in combat in a way similar to how droids are used in Star Wars battles. And if you add aliens, like the Hutts, they could interact with Naruto characters in unique ways, such as trading information or forming alliances. This kind of fanfiction allows for a lot of creative freedom and can bring new and exciting stories.
One way to combine them is to have Naruto characters in a Star Wars - like universe. For example, Naruto could be a Jedi - like figure with his chakra being like the Force. The 'King' could be a powerful Sith - like character who rules over a part of the galaxy. Fanfiction writers can play with the concepts of Naruto's ninja skills and Star Wars' space - faring technology to create unique and exciting stories.
One way to combine them creatively is to have Naruto characters with Rinnegan powers in a Highschool of the Dead - like scenario. For example, the Rinnegan could be used to detect zombies from afar, similar to how it can sense chakra in Naruto. The high school setting could be filled with Naruto - style ninjutsu battles against the undead.
One way to combine them creatively is through a crossover story. For example, Naruto could be transported to the Fairy Tail world and his Kyuubi powers could be mistaken for some kind of powerful magic. The characters from Fairy Tail might initially be cautious or even hostile towards Naruto because of his unknown and powerful abilities. But as the story progresses, they could learn to work together and Naruto could teach them about his world and his ninja skills while also learning about magic from the Fairy Tail mages.
They can be combined by having a shared plot device. Maybe a powerful artifact that is important in both Naruto's world and the High School DxD world. This could bring the characters from both series together. The ninjas could be interested in the artifact for its power to protect their village, while the devils and angels in High School DxD might want it for their own purposes like increasing their power or influence. It could also lead to some characters from each series having to team up to protect or obtain the artifact.
