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.
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.
A plotline could be that there is a powerful new enemy that specifically targets their bonds. This enemy uses illusions and mind - control to try and turn Sasuke against Naruto, or make Sakura distrust Kakashi. They have to fight not only the physical attacks of this enemy but also the mental and emotional turmoil it causes within their group. In the end, they realize the true strength of their relationships and are able to defeat the enemy.
In this fanfiction scenario, Kakashi's failure might cause Sasuke to be more reckless. Sasuke, feeling let down, could go off on his own more often. Sakura, who might have relied on Kakashi to keep Sasuke in check, would then be left to try and deal with Sasuke on her own. This could put a lot of stress on their relationship. She might be more desperate to bring Sasuke back to the right path, but Sasuke could see her as being too pushy, all because of Kakashi's initial failure.
A fanfiction titled 'Sasuke, Sakura, Naruto and Kakashi: United Front' is worth reading. In this story, they have to come together to face an ancient evil that has been awakened. The writer does an excellent job of showing each character's growth and how their combined skills and relationships play a crucial role in the battle against the evil.
One interesting plot could be a story where Sasuke and Sakura have a child, and Naruto and Kakashi become like uncles to the child. They all live in the same village and face new threats together, with the new generation learning from the old. For example, the child might inherit Sasuke's sharingan and Sakura's medical skills, and Naruto and Kakashi help train the child to be a great ninja.
Imagine a fanfiction where Sakura, instead of being in love with Sasuke, has feelings for Naruto all along. This would completely change the love triangle aspect and lead to a lot of interesting interactions between the three main characters. It could also cause Sasuke to re - evaluate his relationship with his teammates.
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 'Naruto Sasuke Sakura Kakashi Team 7' fanfiction is 'Team 7's New Adventure'. It focuses on the team taking on a mysterious new mission outside of the Hidden Leaf Village. The characters are well - written and stay true to their original personalities.
