Well, it could be that in the fanfic, Kakashi saves Naruto from a trap set by Orochimaru. Kakashi arrives just in time, using his lightning - style jutsu to break through Orochimaru's defenses and snatch Naruto away from the clutches of danger. This would create a tense and exciting moment in the story.
In some fanfictions, Kakashi might disguise himself as a sage from an unknown land. He would wear robes with strange symbols, have a long beard (maybe a fake one), and pretend to have great wisdom. By doing this, he can attract the attention of those who seek power or knowledge. He can then use this to his advantage, either to lead them astray if they are enemies or to guide the young ninjas of Konoha if they are friends.
One possible antagonist could be Orochimaru. He has always been interested in Naruto for his Nine - Tails power, so it would make sense for him to be a threat that Kakashi has to protect Naruto from.
One interesting scenario could be Kakashi trying to teach Naruto some basic ninja skills in a fun way while babysitting. Maybe he sets up a mini - training ground in the yard and shows Naruto how to do simple jutsu. Another could be Kakashi having to deal with Naruto's over - the - top energy by telling him epic ninja stories to keep him calm and entertained.
In some fanfictions, Naruto saves Kakashi from the brink of death. For instance, Kakashi could be poisoned by a rare and deadly toxin. Naruto, with his determination, goes on a quest to find the antidote. He overcomes many obstacles, battles different creatures, and finally retrieves the antidote to save Kakashi. This showcases Naruto's loyalty and his growth as a shinobi.
One possible scenario could be Kakashi fails to train Naruto properly. Maybe he misses some crucial aspects of Naruto's development, like not focusing enough on his chakra control early on. Another could be that Kakashi fails in a mission where Naruto is involved, perhaps due to miscommunication or underestimating the enemy.
Another plotline might involve Naruto facing a new and powerful enemy while under Kakashi's tutelage. This could test not only Naruto's skills but also the bond between him and Kakashi. For example, they might encounter a rogue ninja from a hidden village who has a vendetta against Konoha. Kakashi would then have to teach Naruto new strategies to defeat this enemy.
One possible plotline could be Kakashi teaching Naruto some of his unique ninja techniques in more detail, like how to better use the Rasengan. Another could be Kakashi helping Naruto deal with his inner demons regarding being an orphan and the Nine - Tails. Maybe there's a plotline where Kakashi trains Naruto to be a more strategic fighter, not just relying on brute force.
In 'naruto trains himself fanfic', one interesting scenario could be Naruto finding a secluded waterfall area to train his new jutsu. He spends days there, facing the force of the water as he tries to perfect his chakra control. Another scenario might be Naruto training with shadow clones in a dense forest, pushing his limits as he spars with multiple versions of himself.
Well, one interesting scenario could be when the characters from Naruto start sharing their most embarrassing training moments in the group chat. It would be hilarious to see Naruto talk about how he accidentally blew up his own clone during a jutsu practice.
In some fanfics, Naruto might use blades to defend the Hidden Leaf village from a new and powerful enemy. He could be seen using blades to cut through enemy defenses or to perform acrobatic feats while holding the blades, like jumping from rooftop to rooftop in the village and taking out invaders one by one. This would show a different side of Naruto's combat abilities compared to his usual just - using - ninjutsu style.
