Naruto would be a very different kind of character in Game of Thrones. His bright and optimistic personality would contrast sharply with the often - dark and cynical world of Westeros. He would likely be seen as an oddity, but his skills would earn him respect. His loyalty to his friends would be something that some in Westeros could admire, while others would try to use it against him.
In the world of Game of Thrones, Naruto's ninja training would give him an edge. He could scale the walls of castles like Winterfell with ease, much like he climbs trees in his own world. His ability to sense danger through his chakra would be useful in the constantly - dangerous Westeros. Politically, he might try to form alliances based on his sense of right and wrong, which could either lead to great success or get him in a lot of trouble. For example, he might try to protect the smallfolk from the tyranny of some lords, which would make him both a hero and a target.
Naruto's presence in Game of Thrones would disrupt the status quo. His powers are not like any magic in Westeros. He could potentially use his Sage Mode to communicate with the dragons, if he ever got the chance. His values of never giving up and always believing in a better future would be a source of inspiration for some, but also a source of annoyance for those who are set in their ways. He might also introduce new forms of combat training, like his own ninja training, which could change the way battles are fought in Westeros.
Well, Aragorn is from a very different fictional universe than Game of Thrones. But if in a fanfic, he might bring his elvish connections which could be a huge advantage in the power - hungry world of Westeros. He could form alliances with the more honorable houses like the Tullys perhaps, based on his own code of ethics. And his experience in battles against great evils would give him an edge in the many wars that plague Westeros.
The Hulk might be seen as a sort of monster in the context of Game of Thrones. Just like how they have direwolves and dragons, the Hulk could be another mythical - but in this case, suddenly very real - creature. He could be shunned by some and perhaps worshipped as a god by others, depending on how different regions of Westeros react to his existence.
Some Naruto characters could fit well. For instance, Sasuke might be like a brooding assassin in the Game of Thrones world, using his Sharingan to his advantage in battles and political intrigue. He could be a lone wolf, similar to Arya Stark in some ways, but with his own unique ninja skills.
In fanfiction, Aragorn could potentially be a king from a far - off land who arrives in Westeros. He might bring with him a different style of leadership and a sense of honor that is somewhat different from the lords and ladies of Westeros. He could get caught up in the power struggles, especially if he realizes the threat of the Iron Throne being misused. Maybe he would try to form alliances with the more noble houses to bring stability to the land.
Napoleon would be an interesting addition to the Game of Thrones universe. His ambition would surely play a big role. He might see the Iron Throne as a goal worthy of his pursuit. Given his ability to inspire loyalty in his troops, he could gather a strong following among the people of Westeros. He could also bring new military tactics that no one in Westeros has seen before, which would give him an edge in battles.
In a fanfic, Wonder Woman would be a game - changer in the politics of Game of Thrones. Her presence alone would make the power - hungry lords and ladies think twice. She could use her influence to promote peace treaties, as she believes in resolving conflicts without unnecessary bloodshed. And she would not tolerate the abuse of power, like Joffrey's tyrannical rule. She would be a symbol of hope for the common people who are often the victims of the political games in Westeros.
Aquaman could be a very powerful force. He has his own set of powers like super strength underwater and the ability to communicate with sea creatures. In the power dynamics of Game of Thrones, he could side with a particular house and give them an edge in naval battles. For example, if he sided with House Stark, he could prevent the Lannisters from getting supplies by sea.
He could fit in as a hero. For example, he might help Arya Stark in her quest for revenge. His combat skills and ability to strategize would be very useful to her. He could also protect the innocent villagers from the raids of the various warring factions.
He could be an outsider who comes in and disrupts the normal flow of things. Maybe he arrives through some sort of magical portal. He'd then have to figure out the political landscape. He might first ally with the smartest characters like Tyrion, seeing potential in his intellect. And with his knowledge of advanced warfare, he could change the way battles are fought in Westeros.
She could fit in as a spy. Given her ability to deceive and her immortality, she could gather information for different factions. For instance, she could work for the Starks initially, but then switch sides if she saw more benefit elsewhere.
