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.
Well, one popular one might be those that focus on team building among them in a non - romantic yet deep - friendship way. For example, a fanfiction could explore how Kakashi mentors Sasuke and Naruto in a new and unique mission scenario, where they learn to trust each other more deeply. However, it's important to note that 'lemon' often implies inappropriate or adult - themed content in fanfiction, so I would recommend looking for more general, positive and character - growth - focused fanfictions instead.
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.
Sure. Try looking on some Naruto - centered fanfic communities. There are numerous fics that explore the bond between Kakashi and Sasuke in a more platonic or action - adventure - based way. For example, some might center around a mission they go on together where they have to rely on each other's skills to succeed.
Fanfiction.net is also a good place to search. Try to find stories that are tagged as 'gen' (general) which usually means no romantic or adult content. For example, there could be stories about their team - up missions, where they have to rely on each other's skills to overcome obstacles. This way you can enjoy the dynamic between Sasuke and Kakashi in a more family - friendly or platonic context.
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.
Well, a lemon fanfiction usually involves some romantic or at least some sort of emotional relationship. In the context of Naruto, Kakashi, and Sakura, it could explore different scenarios. Maybe it shows an alternate universe where Kakashi has some sort of unspoken feelings for Sakura, and Naruto is caught in the middle. It might also involve some character development that is different from the original series, with the 'lemon' aspect adding a touch of romance or unrequited love.
