In a 'Naruto raised by Kakuzu' fanfiction, the story could start with Kakuzu finding Naruto as an orphan. He decides to take Naruto under his wing not out of kindness but because he sees potential in the boy. Kakuzu would be a strict mentor. He'd train Naruto harshly, which would make Naruto grow stronger quickly. However, Naruto's positive attitude might gradually change Kakuzu's cold - hearted views over time. Naruto could also introduce Kakuzu to the concept of bonds and loyalty in a way that Kakuzu has never experienced before.
One possible plot could be that Kakuzu, with his tough and practical nature, trains Naruto in a very different way from the traditional Konoha style. He might focus more on self - reliance and survival skills. Naruto could learn unique jutsu from Kakuzu related to his earth and water - based techniques.
If raised by Kakuzu, Naruto's view of the ninja world would be different. Kakuzu's focus on self - gain and survival could make Naruto more self - centered initially. But as he grows and interacts with others, his inborn kind - hearted nature would start to emerge. He'd have to reconcile Kakuzu's teachings of looking out for oneself with his own desire to protect and befriend others. He might also develop a more cynical view of the shinobi villages' politics due to Kakuzu's own experiences and views on such matters.
The plot could involve Kakuzu being controlled by a more powerful and evil force. Naruto, after trying to reason with him and failing, has no choice but to kill him. This could also be a part of Naruto's growth, where he realizes that sometimes, in the face of extreme evil, killing is the only option to protect others.
Maybe Kakuzu's bloodline has a hidden sealing technique. In the fanfiction, Naruto is trying to learn more about sealing, and Kakuzu, seeing potential in Naruto, decides to teach him this special bloodline - based sealing technique. However, the Akatsuki finds out and tries to stop them, thinking Naruto will use it against them. This leads to a series of battles and a race against time for Naruto to master the technique.
Maybe for his own gain. Kakuzu might see potential in Naruto and think that by training him, he can use Naruto for some future plan. For instance, if Naruto becomes powerful enough, Kakuzu could use him to take on bigger enemies or get access to certain resources.
In a Naruto Kakuzu bloodline fanfiction, it might explore how the two characters' bloodlines interact if they were related in some way. For example, perhaps there was a long - lost family connection that was hidden, and this connection unlocks a new form for Naruto that combines his Uzumaki bloodline with Kakuzu's mysterious lineage. This could lead to Naruto having enhanced physical strength and durability similar to Kakuzu's tough body.
One common theme is the exploration of differences. Since Kakuzu in the original is a rather cold - hearted character focused on money, a female version often has different values that clash and then blend with Naruto's ideals of friendship and loyalty.
In a fanfiction where Naruto is trained by Kakuzu, Naruto's view of the ninja world might change. Kakuzu has a rather cynical view due to his long life and the many betrayals he has faced. This could either make Naruto more understanding of the darker side of the ninja world or it could make him more determined to change it for the better. On the physical side, Naruto might gain more control over his chakra, as Kakuzu is very proficient in chakra management. He could also learn some new combat strategies that are different from what he has learned from Jiraiya or Kakashi, which would expand his arsenal in battles and make him an even more formidable opponent.
One possible plot could be that Shisui, with his skills and kind heart, trains Naruto in unique ways. He might teach Naruto advanced stealth techniques early on. Naruto could also inherit Shisui's sense of justice and loyalty, which would shape his character differently from the original series. Shisui could also introduce Naruto to different aspects of Uchiha culture, which would give Naruto an edge in understanding his friends like Sasuke better.
One possible plot could be that Naruto grows up with a much more calculating and knowledge - based approach to combat and life in general. Kabuto might train Naruto in various medical ninjutsu and stealth techniques, which could change Naruto's fighting style significantly. He may also be more aware of the darker aspects of the ninja world earlier on.
In a 'Naruto raised by pirates' fanfiction, the story could start with Naruto being orphaned near the sea. A pirate ship discovers him. The pirates raise him as one of their own. He'd have to adapt to their rough and tumble lifestyle. Naruto's positive attitude could influence the pirates, making them more of a family. His ninja skills would be a mystery to them at first. As he grows, he could use his chakra to perform amazing feats on the ship, like powering the sails or creating a protective shield during storms. He might also have a goal to find out about his true origins while still being part of the pirate crew.
