Well, at first, Seven of Nine might see Naruto as an unpredictable variable due to his boisterous personality and his strange powers. Naruto would be amazed by Seven of Nine's cool and collected demeanor. As they interact more, Naruto could show Seven of Nine the importance of emotions and bonds, which are things she's still learning to understand after being freed from the Borg. And Seven of Nine could introduce Naruto to the more logical and scientific way of thinking in the Star Trek universe.
It's not appropriate at all. Fan - created works should be family - friendly and respectful. Sexual fanfiction can make the reading environment uncomfortable and is not in line with the values of most audiences.
One possible plot could be that Naruto, through some sort of interdimensional rift, ends up in the Star Trek universe. He meets Seven of Nine and they team up to fight a common enemy. Maybe a new Borg threat has emerged that neither the Federation nor Naruto's ninja skills alone can handle. They combine their unique abilities, with Naruto's chakra - based attacks and Seven of Nine's Borg - enhanced strength and knowledge of technology.
The theme of redemption can also be found. Seven was once part of the Borg, a force that caused a lot of harm. Some fanfictions focus on her trying to make up for the wrongs that the Borg did in some way, whether it's by helping the victims of the Borg or finding a way to prevent future Borg attacks.
There's a fanfiction called 'Journey with Janeway and Seven' which is really good. It focuses on their adventures together and how they support each other. In this story, their unique personalities shine through as they face various challenges in the Star Trek universe.
A less obvious but still present theme is the idea of cultural exchange. Chakotay has his own cultural heritage from the Maquis, and Seven has her Borg - influenced view of the universe. In fanfiction, they often share these aspects of themselves with each other. This can lead to interesting discussions and moments of self - discovery. For instance, Seven might learn about Chakotay's spiritual beliefs, and he might learn about the Borg's efficiency - based way of thinking. It enriches their relationship and the story as a whole.
One common theme is power. Both Naruto and the Seven Deadly Sins series have characters with strong powers. So in the fanfiction, it's often about how the powers interact or combine. Another theme is redemption. Just as some characters in Naruto seek redemption, the concept of the Sins being redeemed is also explored in these crossovers.
One common theme is the clash of different power systems. Naruto has his chakra - based ninjutsu and the characters in The Seven Mortal Sins have their own unique powers. Another theme is friendship. Just like in Naruto where friendship is highly valued, in these crossovers, Naruto forms new friendships with the characters from The Seven Mortal Sins.
One interesting Naruto x The Seven Deadly Sins fanfiction could be one where Naruto has to face the challenges similar to those in The Seven Deadly Sins world. For example, he might encounter characters with powers based on the sins. Maybe a character like Meliodas from The Seven Deadly Sins could meet Naruto and they have to team up to fight a common enemy. It would be fascinating to see how Naruto's ninja skills blend with the magic of The Seven Deadly Sins world.
Obviously Naruto and the Nine Tails themselves are extremely popular. Naruto is the main character of the original series and his relationship with the Nine Tails is central to the fanfiction. But other characters like Kakashi can also be popular in these fanfictions. Since he is Naruto's teacher, he might be involved in training Naruto when the Nine Tails' influence is changing Naruto's abilities. Also, Sasuke can be a popular character. His rivalry with Naruto can take on new dimensions in Naruto x Nine Tails fanfiction, especially if the Nine Tails' power gives Naruto an edge that Sasuke wants to equal or surpass.
