In a Game of Thrones fanfiction, Hermione might play the role of a disruptor. She's not from that world and has different values. Her presence would disrupt the status quo. For instance, she would not tolerate the way women are often treated in Westeros. She'd speak up and fight for equality, which would put her at odds with many of the traditional lords. At the same time, her magical abilities would make her a force to be reckoned with, so she could start to change things whether the people in Westeros like it or not.
She could be a maester - like figure. With her vast knowledge, she could advise rulers on various matters, from war strategies (using her strategic thinking from Hogwarts battles) to matters of health and economy. She'd be different from the traditional maesters as she has a more modern - thinking approach.
He could play the role of a master strategist. Thrawn's ability to analyze his opponents and predict their moves would make him a valuable asset to any side in the 'Game of Thrones' power struggles. He could be the one to turn the tides in battles and sieges.
In a Game of Thrones fanfic, Hermione could be a mediator. There are so many conflicts in Westeros, from the Stark - Lannister feud to the battles for the Iron Throne. Hermione, with her logical mind and ability to see different perspectives, could step in and try to broker peace deals. She would use her communication skills, honed in the wizarding world, to get the warring parties to at least listen to each other and consider alternatives to all - out war.
Hashirama might become a powerful ally or a feared enemy in the Game of Thrones fanfiction. If he aligns himself with a certain house, his powers would make that house very difficult to defeat. He could also be a lone wanderer, using his skills to help the common folk. For instance, he could use his wood - style jutsu to create shelters for the poor or to clear paths in the forest for travelers. He would be like a force of nature in the world of Westeros, disrupting the normal power dynamics.
Hermione could potentially belong to House Lannister. Now, the Lannisters are known for their cunning and wealth. Hermione's intelligence could be seen as a form of cunning. She could use her magic to help the Lannisters in their financial schemes, perhaps by using magic to find hidden treasures or to create valuable items. Also, she could use her magic to protect the Lannisters from their enemies, which would be highly valued by the family.
Rome could play the role of a mysterious foreign power. It might send envoys to the Seven Kingdoms to form alliances or gather information. This would add an extra layer of diplomatic intrigue to the story.
She could be a healer. With her knowledge of medical ninjutsu, she could save many lives in the war - torn Westeros. This would make her a valuable asset to any side she chooses to support.
He could be a heroic figure. For example, he could be like a knight - errant, traveling around Westeros and helping those in need. His swordsmanship, which is quite different from the traditional Westerosi style, would make him a unique combatant.
Wolverine might be a disruptor in the Game of Thrones world. He doesn't follow the same rules as the Westerosi. His presence could change the way battles are fought. For example, in a large - scale battle like the Battle of the Bastards, his individual combat skills could turn the tide. He could cut through enemy lines with his claws and inspire the troops he's fighting alongside. He might also be a voice of reason among the power - hungry lords, as he has his own sense of right and wrong that is different from the political games in Westeros.
She could be a powerful sorceress. In the world of Game of Thrones, magic is a mysterious and dangerous force. Bella might be someone who has been secretly studying magic, perhaps in the far reaches of Essos. She could use her powers to manipulate the political situation in Westeros, for example, by influencing the minds of the lords and ladies during their councils. This would add a new and interesting dynamic to the complex web of power struggles in the series.
