His relationships could be strengthened. His friends might be in awe of his new abilities and look up to him more. They could also be a bit jealous at first, but then realize they can all grow together. For example, Sasuke might see Naruto's new powers as a challenge to overcome himself.
The training with dragons would have a complex impact on his relationships. His sensei, like Kakashi, might be both proud and a bit worried. Proud because Naruto is growing stronger, but worried about the unknown aspects of the dragon training. His relationships with the other villagers could also change. Some might fear his new powers, while others would see him as an even greater hero. And with his friends, it could lead to new adventures where they all have to adapt to Naruto's new abilities and find ways to work together effectively.
With Sasuke, it could either drive a wedge or bring them closer. If Sasuke blames himself for Naruto getting injured while protecting him, he might distance himself out of guilt. On the other hand, it could also make Sasuke realize how much Naruto means to him and he could become more committed to their friendship.
His apathy can strain his relationships. His friends might feel neglected. For instance, Sakura could be confused and hurt as Naruto no longer shows the same eagerness to be part of the team.
Well, it could make him more desperate to catch up. He might become more self - doubting at first. But then, as he realizes his mistake, he could develop a stronger sense of determination to overcome his lack of training. For example, he might start training in more unorthodox ways to make up for lost time.
Well, it definitely slows him down. He can't push himself as hard as he usually does. His stamina is lower, so he might not be able to complete his normal training routines.
His illiteracy might make his friends initially frustrated. For instance, Sasuke, who is more studious, could be impatient with Naruto's inability to read important messages. But as they grow, they might become more understanding.
It can create misunderstandings. For instance, his friends might think he doesn't like them if he recoils from their touches. His romantic relationships could also be affected. If he's in love with someone in the fanfiction, his fear of touch would make it difficult for him to show physical affection, which is an important part of a romantic relationship.
His friends might start to avoid him. If Naruto is constantly snapping at them, they'll feel hurt and not want to be around him as much.
The Uzumaki bloodline can also affect his relationships with characters from other villages. In fanfiction, ninja from other villages who know about the Uzumaki's power might either fear or respect Naruto more. This could lead to different diplomatic situations. For example, a village might be more willing to negotiate with the Hidden Leaf because of Naruto's Uzumaki bloodline. On the personal level, he might meet other Uzumaki descendants in other villages, and they could form a strong bond based on their shared bloodline.
His depression could strain his relationships with his friends. They might not understand why he has become so withdrawn and moody. For instance, Sakura might try to reach out to him, but Naruto could push her away, causing a rift in their friendship.
In terms of his romantic relationships, if a love interest discovers the seal on his heart, it could either draw them closer or create distance. If they are understanding and want to help, it could strengthen their bond. But if they are afraid of the unknown associated with the seal, they might pull away. For example, Hinata might be initially scared but then resolve to stand by Naruto and help him understand the seal.
