In a more emotional plot, Naruto is banished because the villagers still fear the Nine - Tailed Fox within him. Naruto, heartbroken, sees Kakashi as someone who could have stopped this but didn't. The fight then becomes not just a physical struggle but also a battle of Naruto's self - worth and his relationship with Kakashi. As they fight, Naruto might be trying to make Kakashi understand his pain and also hoping for some form of redemption or acceptance from the village through Kakashi.
One possible plot could be that Naruto is wrongly accused of a serious crime in the village and is banished as a result. Feeling betrayed, he decides to confront Kakashi, who he may see as representing the village's unjust decision. The fight could be a way for Naruto to vent his anger and also prove his innocence.
Perhaps there are political machinations within the Hidden Leaf Village. Some powerful figures want Naruto out of the way for some reason, so they frame him and get him banished. Naruto, having grown strong on his own outside the village, returns to face Kakashi. Kakashi, on the other hand, is conflicted because he believes in Naruto but is also bound by the village's rules. The fight could be a complex battle of ideologies as well as physical combat.
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.
Well, one possibility is that Naruto's ability to melt the fireball reveals a new and unexpected power within him. This could lead to Kakashi taking a special interest in training Naruto further to explore and control this power.
It could be that Temari accidentally causes a major disaster during a joint mission with Konoha. The Konoha elders, fearing public outcry, banish her. Naruto, who has befriended Temari, doesn't believe she did it on purpose. He then sets out to uncover the real cause of the disaster, which may involve a hidden enemy who framed Temari. Along the way, he has to convince his village that banishing Temari was a wrong decision.
In the Naruto Banished Pokemon Fanfiction, it could be that a powerful villain has the ability to control Pokemon and is using them to attack Naruto's world. Naruto, having no other choice, decides to banish the Pokemon to a different dimension to stop the attacks. However, later he discovers a way to break the villain's control over the Pokemon and has to go on a journey to bring them back and form an alliance with them to defeat the real enemy.
Perhaps a new threat emerges that specifically targets Naruto when he was younger. Kakashi and Naruto from the present must enter a hidden dimension where the younger Naruto is trapped. There, they encounter strange creatures and challenges. Along the way, Kakashi teaches Naruto more about his Sharingan and how to use it effectively to protect the young Naruto. As they progress, they discover that the real mastermind behind the threat is someone they least expected, and they have to use all their skills to defeat this foe and return to their own time.
Another motive might be related to some dark power corrupting Team 7. This power could have twisted their minds and made them see Kakashi as an obstacle in their path to achieving ultimate power. It could be something like the curse mark in the original Naruto series but even more powerful and insidious.
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.
