His relationship with Sasuke would be very different. In the new dimension, Sasuke might not have the same vendetta against his brother. So Naruto wouldn't have to worry about Sasuke going off the rails. With Sakura, she could be a powerful ninja in a different way, like she might be more focused on medical ninjutsu and Naruto would see her in a new light. And his relationship with Kakashi could change too. Maybe Kakashi is a strict military - like leader in the other dimension instead of a laid - back teacher.
Naruto's relationships would change significantly. In the new dimension, he may find that his friends are now his enemies or vice versa. His friendship with Kiba, for example. Kiba could be part of a group that is against Naruto's arrival in the new dimension. On the other hand, Naruto might meet a new character who becomes his closest ally, someone who understands his situation of being from another dimension. His relationship with the Hokage in the new dimension would be complex. If the Hokage is more power - hungry, Naruto would have to oppose him, which is different from his relationship with the Hokage in his own dimension.
If Naruto travels to another dimension, his relationship with his friends would be transformed. For instance, his bond with Shikamaru. In the new dimension, Shikamaru could be a lazy king instead of a lazy ninja. Naruto would have to adjust to this new Shikamaru and their relationship would be based on different dynamics. His relationship with Hinata might also change. Hinata could be a confident and outgoing ninja in this dimension, and Naruto would be attracted to her in a different way than in his own dimension. Also, Naruto's relationship with the village elders would be different. They might see him as a threat instead of a hero in this new dimension.
Well, Naruto's relationship with the villagers would be quite different. Instead of being the outcast he was as a child, he could use his knowledge of the future to show his worth early on. This might lead to more positive interactions with the villagers. And his relationship with his friends like Shikamaru and Choji could also be enhanced as he could introduce more interesting things to them at an earlier stage.
If Merlin travels back in time, his relationship with Arthur would be very different. In the past, Arthur might not trust him at all at first. Merlin would have to prove himself all over again. With Gwen, he might be more aware of her future importance and try to protect her in a different way. And his relationship with the other knights could be completely new, as they might see him as a stranger with strange powers.
If Naruto were not human, his relationships would likely be very different. For example, his relationship with Sasuke might be more strained. Sasuke, who is very focused on power and revenge, might see Naruto as a greater threat if he's not human. He could view Naruto's non - human abilities as something to envy or fear. With Sakura, she might be more hesitant around Naruto. Instead of her initial crush, she could be more cautious, not knowing what Naruto is truly capable of.
With Sakura, she might be initially afraid of Naruto's demon form. But as she realizes that Naruto is still the same person inside, she could become more protective of him and help him control his powers. Their friendship could deepen in a different way compared to the original story.
If Ianto travels back in time, his relationships with the Torchwood team in his original time would be put on hold. They would be left wondering where he went. In the past, he might form new relationships. For example, he could become friends with an ancestor of one of his present - day colleagues. This would create a strange connection between the past and the present for the team when he eventually returns.
His relationship with his father Poseidon would be different. He might see a side of Poseidon that he never knew before, like when Poseidon was younger and less experienced. This could change how Percy views his father and their connection.
With the other Robins, like Dick Grayson and Jason Todd, his relationships would vary. If he was from a more violent universe, he might not get along with Dick's more positive and acrobatic approach. And he could have a more competitive or even hostile relationship with Jason if they were both vying for the same territory or resources in Gotham.
His relationship with Sasuke would likely be affected. Sasuke might be both intrigued and wary of Naruto's hollow abilities. They could have new reasons for rivalry, like Sasuke wanting to prove he's stronger despite Naruto's unique powers. Or, they could end up teaming up earlier to figure out what Naruto's hollow nature means.
Naruto's relationship with the other Leaf Village ninjas would also shift. Some might be suspicious of his new - found admiration for Itachi, especially those who were directly or indirectly affected by Itachi's actions. However, others who understand Itachi's true motives, like Kakashi, might support Naruto. This could create a complex web of relationships within the village, with Naruto at the center trying to balance his new beliefs and his old friendships.
If Naruto were born an Uchiha, his relationship with Sakura might be affected. Sakura might be more drawn to him initially because of the allure of the Uchiha clan. However, Naruto might be more focused on restoring the Uchiha name and proving that they are not all bad. His relationship with the villagers would be complex. Some would be fearful, while others might hope that he could use his Uchiha powers for the good of the village.
