Well, characters like Lightning from Final Fantasy XIII would be a force to be reckoned with in Westeros. She's used to fighting against powerful foes and oppressive systems in her own world. In Game of Thrones, she could side with the underdogs, like the Starks perhaps. Her combat abilities are top - notch, and she could easily hold her own in battles, whether it's a large - scale war or a one - on - one duel. She might also question the social norms in Westeros, such as the treatment of women, and try to make a change in her own way.
In fanfiction, characters from Final Fantasy could fit into Game of Thrones in various ways. Take Aerith from Final Fantasy VII. She has a connection to the planet's life force. In Westeros, she could sense the magic in the land and the approaching threats. Her gentle nature might initially make her seem like an easy target, but her knowledge of nature - based magic could be a great asset. She could potentially heal the wounded in battles or use her powers to influence the growth of crops, which would be crucial in a world where famine is a real threat.
The characters from Final Fantasy would bring their unique skills and personalities. For instance, Tidus from Final Fantasy X with his blitzball skills could be like a new form of entertainment in Westeros. His positive and somewhat naive personality might make him an easy target for some of the more cunning characters at first. But his determination and fighting skills would also earn him respect. He could get involved in local disputes and use his skills to help those in need, while also trying to understand the complex power dynamics of the Seven Kingdoms.
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.
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.
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.
The Basilisk could be a fearsome weapon. A powerful lord might capture it and use it to strike fear into his enemies. Just like how dragons are used in Game of Thrones, the Basilisk could be a game - changer in battles.
Percy Jackson would be a very interesting addition to the Game of Thrones world. His ability to control water would be a huge asset in battles. For instance, he could create floods to stop enemy armies or use water to put out dragon fire. In the political arena, he might be seen as a threat by some because of his powers, but also as a potential ally by others who want to use his abilities for their own gain.
Link would be an outlier in the GoT world. He's used to a more straightforward good - vs - evil dynamic. But in Westeros, he'd have to navigate the complex web of politics. He could probably be a great warrior in the service of a noble house, but his simple and pure-hearted nature might make him a target for the more devious characters. Zelda could be a powerful sorceress, perhaps on par with Melisandre, but with her own goals and a different moral compass.
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.
They could be a new faction. Samurai have a strict code of honor, much like the knights in Westeros. They might be seen as a threat initially, but could also form alliances. For example, they could side with the Starks who also value honor. Their unique fighting styles would be a novelty in the battles of Westeros.
A house gardener could fit in as a keeper of secrets. The gardens often have hidden corners and old trees that could hide things. He might stumble upon a hidden cache of weapons or a secret meeting place. His presence is often overlooked as he is just a gardener, so he can observe a lot without being suspected.
He could fit in as a hero. Just like in his own world, he would fight against the evil forces in Final Fantasy. For instance, if there was a dark sorcerer threatening the land, Naruto would step up to protect the innocent. His ability to make friends easily would also help him gather allies from different parts of the Final Fantasy world.
