He might use his ninja skills to survive in Westeros. His ability to move stealthily and his combat skills could make him a formidable figure. He could also form alliances with some of the characters in Westeros, perhaps teaching them some of his ninja techniques in return for knowledge about the land.
He might interact with Jon Snow. They both have a sense of honor and duty, so they could become friends or allies. Maybe they would fight together against the White Walkers.
One interesting plotline could be Ash having to adapt to the unique political system in Westeros. Maybe Ash gets involved in the power struggles between the great houses. Another could be Ash forming unexpected alliances, like with the wildlings. And Ash might also bring some new skills or knowledge from their original world that gives them an edge in Westeros.
Well, Sandor Clegane, the Hound, could be a popular character to interact with Ash. His rough exterior and complex personality would be a contrast to Ash. Also, Samwell Tarly. His love for knowledge and his kind heart could make him a great friend or ally to Ash. And Melisandre. Her connection to the Red God and her prophetic abilities would create some really intense and mysterious interactions with Ash.
Naruto would probably find the social hierarchy in Westeros quite strange at first. But his friendly and adaptable nature would help. He might start at the bottom, but his skills would quickly earn him respect. He could become a sort of outsider hero, not fully bound by the strict rules of the hierarchy.
If Harry Potter ends up in Westeros in a fanfic, he could bring some new ideas about magic. The people of Westeros are used to their own kind of sorcery. Harry, with his knowledge of spells like Expelliarmus and Wingardium Leviosa, might either be seen as a great asset or a threat. He could also make friends with some of the characters. For example, he might bond with Arya Stark over their shared skills in combat and stealth, albeit in different ways. He could also potentially teach some of the younglings in Westeros about his type of magic, which could change the balance of power in the land.
He would probably start by trying to understand the magic in Westeros. Since it's different from what he knows, he'd need to be cautious. Maybe he'd find some similarities between the two magics and build on that.
Well, Naruto's ninja skills would be a huge shock to the people of Westeros. He could easily outmaneuver the knights with his speed and agility. His shadow clone jutsu could be used for various strategic purposes, like spying or creating diversions during battles.
X 23 would have to rely on instincts at first. Since X 23 has combat skills, those could be used for self - defense and survival. For example, if attacked by a wild animal, the fighting skills would come in handy.
Jon Snow might be an ally too. He has a good heart and is used to dealing with different cultures and powers. He and Naruto could bond over their shared experiences of leadership and fighting for what's right.
