In this fanfic, Naruto could become a mini Kakashi in terms of his laid - back attitude. Normally Naruto is very energetic, but after idolizing Kakashi, he might start to take things a bit more casually, much to the surprise of his friends. He could also start using Kakashi's catchphrases, like 'I'm late' even when he's not actually late, just for the fun of it.
The plot could involve Naruto seeing Kakashi as the ultimate ninja and trying to learn all of his non - jutsu related skills. For example, Kakashi is often seen reading his 'Make Out Paradise' books. Naruto might start carrying around a similar - looking book just to be like Kakashi. And in battles, Naruto might use Kakashi - like strategies, such as using misdirection and feints more often.
The plot could be that Naruto gets a special mission to protect Kakashi's face from a group of rogue ninjas who want to steal Kakashi's identity. Naruto has to use his unique skills to fend off the attackers and keep Kakashi's face safe.
Well, the plot could revolve around Kakashi providing Naruto with a more stable family - like environment. He might cook for Naruto, help him with his studies at the ninja academy in a more hands - on way, and also be there to support Naruto emotionally when he has nightmares about being alone. This could lead to Naruto growing up more confident and perhaps even developing new skills faster as he has someone constantly guiding him.
One possibility could be a misunderstanding. Maybe Kakashi is framed for something that makes Naruto believe he has betrayed him. For example, an enemy could use a clone of Kakashi to perform a heinous act, and Naruto witnesses it without seeing the full picture.
Well, it could be that in this fanfic, Kakashi discovers a new potential in Naruto. He might train Naruto in some ancient and forgotten ninja arts. This would set Naruto apart from his canon self. Also, their relationship could be explored more deeply, like Kakashi becoming a father - figure to Naruto, and this emotional bond could influence Naruto's growth as a ninja.
A possible plot could be that in a mission gone wrong, Naruto and Kakashi get separated from the rest of the team. They end up in a strange place where they have to rely on each other more than ever. As they face various challenges together, their bond deepens and Naruto realizes his feelings for Kakashi, leading to a kiss.
His relationship with Sasuke would be interesting. Sasuke might be a bit confused or even annoyed at first. He's used to Naruto being his own energetic self, and now Naruto is acting like Kakashi. Sasuke might see it as Naruto trying to be something he's not. But over time, he could come to respect Naruto's new - found admiration for Kakashi and see it as Naruto growing as a ninja.
One possible plot could be that Kakashi discovers Naruto is his son in a surprising turn of events. Maybe there was some hidden truth about Naruto's birth that was concealed all this time. Kakashi then has to deal with the newfound father - son relationship while also guiding Naruto in his ninja training. He could be more protective and pass on some of his unique skills more intimately.
One possible plot could be that Naruto is already a respected ninja in the village. He's assigned to a special mission to deal with a new threat that's related to an old enemy of Kakashi's. Since he's at Kakashi's age, he has the skills and knowledge to handle complex situations. Along the way, he discovers secrets about his own past that are linked to this new threat. He has to use his experience and the bonds he's made over the years to overcome the challenges.
One possible plot twist could be that Kakashi discovers Naruto has a hidden power that no one else is aware of. This could change the whole dynamic of their relationship. Maybe it's a new type of chakra that only Kakashi can help him control.
Maybe in the fanfic, Naruto is napping after a tough training session. Kakashi comes by and uses this opportunity to leave some encouraging notes or small gifts for Naruto. Later, Naruto discovers these and it gives him an extra boost of motivation. It could also lead to a humorous scene where Naruto tries to figure out who left them while Kakashi secretly watches.
