One way could be through a magical portal. Imagine in a fanfic, a powerful mage in the Game of Thrones world accidentally opens a portal to the Naruto universe. Dark Naruto, with his edgy and powerful nature, could be seen as a threat similar to some of the dark forces in Game of Thrones. He might form an alliance with a power - hungry lord in Westeros, thinking he can use their resources to achieve his own goals in the Naruto world. For example, if he teams up with Littlefinger, they could plot to take over both kingdoms using Dark Naruto's powers and Littlefinger's cunning.
Naruto in the Game of Thrones universe might struggle with the moral ambiguity that exists there. In his own world, he has clear ideas of good and evil, but in Westeros, things are not so black and white. He may try to introduce his values of friendship and loyalty, which could either be embraced or rejected by the inhabitants of this new world.
If Dark Naruto were to face off against Jon Snow, it would be a tough fight. Jon Snow is a skilled swordsman and a great leader. However, Dark Naruto has his powerful ninjutsu. He could use his Rasengan to quickly overpower Jon Snow. Dark Naruto's speed and agility would also give him an edge as he could dodge Jon's sword strikes easily.
Naruto would probably be excited by the new challenges. He'd see the power struggles in Westeros as another chance to prove himself. His ability to make friends easily would help him form alliances. For instance, he could bond with the Stark family over their sense of loyalty.
Naruto characters would likely be confused at first by the different rules and cultures in Game of Thrones. For example, Sasuke might see the backstabbing in Westeros as similar to the politics in the ninja world but on a more brutal scale. In terms of the lemon aspect, if there were a relationship between a Naruto character like Sakura and a GoT character like Tyrion, their interactions would be full of misunderstandings and yet also a growing respect. The Naruto characters' combat skills would also play a role, with their jutsu being a new and terrifying form of combat for the GoT characters.
If Naruto was a Lannister in a Game of Thrones fanfiction, he'd be a very different kind of Lannister. He'd probably use his ninja skills to protect the family in ways they've never seen before. Instead of the usual backstabbing, he might bring in a sense of loyalty and honor that the Lannisters lack. He could use his jutsu to make the Lannister stronghold more secure, like creating barriers with his earth - style jutsu.
A possible plot could involve a great threat that requires the combined forces of both worlds. Magic from both universes might be the key to defeating this threat. The Targaryens' dragons could be compared to some of the powerful beasts in Naruto. And the idea of the Iron Throne could be something that Naruto characters might not understand at first, but as they get involved in the politics of Westeros, they start to see the importance of power and control. This fanfiction would be full of adventure, political drama and magical battles.
Yes, there might be. You can start by checking fanfiction websites like Archive of Our Own or FanFiction.net. There could be some creative writers who have combined the elements of Naruto's god - like abilities with the complex political and fantastical world of Game of Thrones.
Survival is also a key theme. In Game of Thrones, characters are constantly fighting for survival in a brutal world. When combined with the Dark Phoenix, which has its own battles for survival against its inner demons, fanfictions create complex and engaging stories about characters trying to stay alive in the face of great danger.
One idea could be to explore what would happen if a minor character from the series, like Gendry, had secretly been trained in magic all along. Another could be a fanfiction where the White Walkers and the humans form an uneasy alliance against a new, even greater threat from Essos. Or perhaps a story where Daenerys doesn't go mad, but instead finds a way to truly bring peace to Westeros through diplomacy and understanding.
