It would be very close. Kakashi would be like a father or an older brother to them. Naruto and Sasuke would respect and rely on him. They would probably have a more harmonious relationship with each other too, because Kakashi would be there to mediate any conflicts.
One great fanfiction could be 'The Bond Beyond Teams' which focuses on the complex relationships between Kakashi, Naruto and Sasuke. It delves deep into how their individual growth affects their bond with each other. Another good one is 'Naruto's Unseen Path' where Sasuke and Kakashi play important roles in Naruto's journey to discover a new power. There are also fanfictions that explore alternate universes, like 'Parallel Konoha' where the three characters have different roles and personalities yet still maintain their core essence.
Well, Kakashi's adoption would likely bring more stability to their lives. He could train them more intensively and offer better guidance. Naruto might finally feel like he has a proper family, which could boost his self - confidence. Sasuke, on the other hand, could find a new sense of belonging and might be less likely to go down the dark path he did in the original story.
Power and its limits is another one. In these fanfictions, we see them constantly testing their powers. Naruto might be trying to master new jutsus without losing himself. Sasuke could be grappling with the power of his Sharingan and how far he should go with it. Kakashi, with his Sharingan and his own unique skills, also serves as an example of someone who has learned to control and use his power effectively within certain limits.
A fanfiction where they all go on a mission together in a strange, uncharted land. Kakashi is the leader as usual. Sasuke could struggle with his inner demons during the mission, Naruto would be trying to keep everyone's spirits up, and Sakura would be using her medical skills to keep them all in top shape. There could be new enemies and challenges that they have to face together, forcing them to rely on each other more than ever.
One idea could be a time - travel fanfiction. Naruto, Sasuke, Sakura, and Kakashi are sent back in time to their early days at the academy. They have the knowledge of their future selves and use it to change some of the events that led to hardships in their lives. For example, Sasuke could prevent the Uchiha massacre with their combined help.
Yes, there might be some fanfictions out there with such an unusual plot. However, it may not be a very common or mainstream concept in the fanfiction community. Fanfiction often explores creative and sometimes out - of - the - box ideas, and this would be one of them.
Well, in fanfiction, Kakashi might seem to favor Sasuke because Sasuke is extremely talented. He has a natural aptitude for jutsu and a strong drive for power. Kakashi, being a great ninja himself, would recognize this potential and be more drawn to mentoring Sasuke to help him reach his full potential.
The fanfiction would likely show a different side of their development. Since Kakashi is a very experienced ninja, he could expose Naruto and Sasuke to different types of missions earlier. This would accelerate their growth not only in terms of combat skills but also in terms of understanding the ninja world. And with Kakashi as their adoptive father - figure, they would have a stronger emotional support system, which could potentially prevent some of the tragedies that happened in the original story.
One common theme is friendship. Given their long - standing relationships in the original series, fanfictions often explore how Sasuke, Sakura, Naruto, and Kakashi's friendships evolve over new challenges. Another theme is power and growth. Fans like to write about how these characters continue to gain strength and wisdom.
