Naruto's relationship with his enemies would surely be affected. Enemies might target him more if they think his red hair is a sign of a new power they can steal or a weakness they can exploit. On the other hand, some enemies might be more hesitant to attack him, fearing that the red hair is a sign of a new and unknown strength. His relationships within the ninja world in general would be in flux, as everyone tries to figure out what this red - haired Naruto means for the balance of power.
Well, having Kushina's hair could make Naruto look more like his mother. It might add a touch of softness to his overall appearance. Maybe in the fanfiction, it's a symbol of a deeper connection to his mother's side of the family, like a heritage thing.
Well, in some fanfictions, Naruto might cut his hair as a symbol of a new beginning. Maybe he's been through a tough time and wants to change his look to show that he's growing and evolving.
If Naruto finds his mother's sword in a fanfiction, it might lead him on a journey of self - discovery. The sword could be a symbol of his heritage. It could also attract the attention of enemies who either feared his mother or want the power of the sword for themselves. This would then put Naruto in a dangerous yet exciting situation where he has to protect the sword and learn about its significance.
His long hair might make Sakura see him in a different light. Maybe she starts to notice his more mature side with the long hair and becomes more attracted to him. It could also change his relationship with Sasuke. Sasuke might initially mock his new look but later come to respect the power that seems to be associated with Naruto's long hair.
Often, he's still portrayed as the determined and energetic ninja. His orange hair is like a symbol of his unwavering spirit. For example, in some fanfics, his hair seems to shine even brighter when he's about to perform a really difficult jutsu, emphasizing his focus and power.
One possible plotline could be that Naruto's silver hair is a result of a powerful curse placed on him. This curse could be related to an ancient evil that is trying to use Naruto as a vessel. So, the story could revolve around Naruto trying to break this curse while still being the hero he is. Another plotline might be that his silver hair is a sign of a new chakra form he is developing. He then has to learn how to control this new form and use it to protect the village from a new threat.
In some fanfictions, Naruto's mother might be a character related to the Uchiha clan in a unique way. It could be someone who was secretly in love with an Uchiha and had Naruto as a result. Maybe she was a long - lost relative of the Uchiha who was trying to protect the clan's secrets through Naruto.
Maybe he found some hidden scrolls left by his mother. These scrolls could have contained the details of her jutsu. Naruto, being the curious and determined ninja he is, would have studied these scrolls carefully and learned the jutsu.
