In fanfiction, Naruto might not wear orange because he's trying to reinvent himself. He could be in a new phase of his life where he wants to be more respected and taken seriously. Orange gives off a more carefree and youthful vibe, and he may feel that it's holding him back. Another possibility is that there's a cultural or social shift in the fanfiction world he's in. Maybe in that world, wearing orange is associated with something negative or is simply out of fashion, so he opts for a different look.
In the fanfiction world, Naruto may have outgrown his old self. Orange was part of his younger, more carefree identity. Now, if he's becoming more serious or has a new role to play, he might hate orange as it represents a time he no longer wants to be associated with. He could be trying to reinvent himself and the color orange is a hindrance to that.
Maybe it was a spell gone wrong. A misfired charm could have transformed his shoes into high heels.
One reason could be simple curiosity. Naruto might be interested in seeing how fans from the Bleach fandom imagine different storylines. Another reason could be to gain inspiration for his own ninja world. Since Bleach has unique concepts like Soul Reapers and Hollows, Naruto could be looking for fresh ideas that he can adapt to his own battles and relationships in Konoha.
Perhaps the fanfiction alters the relationship between Kakashi and Naruto in a way that Kakashi doesn't like. Maybe it shows Kakashi as being overly harsh or unfair to Naruto in a situation where in the original series he wouldn't be. It could also be that the fanfiction contains plot elements that Kakashi, as a character, would find illogical or against the spirit of the Naruto world.
One reason could be to explore a different side of Naruto. Maybe the writer wants to show how even a character as positive as Naruto could break under extreme circumstances. Another reason might be to create a more complex and less idealized version of Naruto.
Perhaps the writer wants to create a more 'adult' or 'mature' version of Naruto. By having him smoke, it gives an impression of a character who has seen a lot and is dealing with his problems in a less - than - ideal way. It could also be a way to shock the readers and make them see Naruto in a completely new light.
Well, it could be due to a clash of values. Naruto has his own ninja code and beliefs from his world. The Olympians might have different ideals like competition for glory which Naruto may see as self - centered compared to his more community - based ninja values.
One possible reason could be a traumatic event. Maybe he witnessed something so horrible that it made him shut down his emotions to protect himself. For example, if he saw all his friends killed in front of him, it could be too much for him to bear and he just numbs himself.
Well, one reason could be that Hinata's extreme love for Naruto gets out of hand. In the original series, she's very shy but deeply in love. In a fanfiction, this love could transform into an obsessive - like stalking behavior if the writer wants to explore a darker side of her character.
Perhaps Kakashi feels that Naruto is becoming too reliant on him and not developing his own skills independently. So, in order to force Naruto to become stronger on his own, he decides to abandon him. This is a tough - love approach. Naruto has great potential, but he needs to learn to stand on his own two feet, and Kakashi may think this is the best way to make that happen.
