Well, in a 'naruto possessed by evil fanfiction', Naruto could be made to do all sorts of uncharacteristic things. His sense of justice could be warped, leading him to believe that the only way to achieve peace is through domination. He may also develop new and dark jutsu, and his relationships with characters like Sasuke and Sakura would be severely strained as he becomes a threat to them.
Obviously, Naruto is the main character as the story revolves around him being possessed by the Kyuubi. Sakura and Sasuke could also play important roles. Sakura might be worried about Naruto and try to find a way to help him break free from the possession. Sasuke could be either an ally or an antagonist depending on the plot. He might see Naruto's new - found power as a threat or a means to achieve his own goals.
In this type of fanfiction, the development could be quite complex. Initially, the evil possession might be subtle, with Naruto just having some strange thoughts or minor outbursts. But as time goes on, it would fully take over. His relationships would crumble. He might target his former mentors, like Kakashi, thinking they are holding him back. His actions would draw the attention of other ninja villages, who might see this as an opportunity to attack Konoha. Meanwhile, some characters in Konoha might believe there's still good in Naruto and try to reach out to him, while others would be ready to eliminate the threat he poses. This would create a lot of internal and external conflict, driving the story forward in a very different direction compared to the original Naruto storyline.
One interesting plot could be Naruto learning to control the Kyuubi's power in unique ways that are different from the original story. For example, he might be able to use the Kyuubi's chakra to create new jutsu that are a combination of his own skills and the Kyuubi's raw power.
One popular 'Naruto Possessed' fanfiction could be 'Naruto: Possessed by the Nine - Tails' Power'. It often explores how Naruto's already formidable power is enhanced and changed by a more intense connection to the Nine - Tails. Another might be 'Naruto: Possessed by a Mysterious Force' which delves into how he copes with a new, unknown power within him. And 'Naruto: Possessed by the Spirit of an Ancient Sage' where he gains the wisdom and abilities of an ancient being.
The unique feature is often the new powers Naruto gets. For example, in many 'possessed Naruto fanfic', he might gain dark or ancient powers that are not part of his normal abilities in the original series. This can lead to very different fight dynamics.
One common plotline is the struggle for control. Naruto has to fight against the entity possessing him, like in many fanfictions where he battles his own body's takeover. Another is the reaction of his friends. They usually try to find a way to save Naruto, which often involves researching ancient texts or seeking out powerful ninja who might know a solution.
One popular 'Naruto gets possessed' fanfiction is 'Possessed Naruto: The Dark Path'. In this fic, Naruto is possessed by a powerful and ancient spirit, which leads to a whole new set of challenges for him and his friends. Another one could be 'Naruto's Possession: A New Power Unleashed', where the possession actually gives Naruto some unexpected abilities that he has to learn to control.
