In the fanfiction, perhaps Itachi trains Naruto to be able to counter the Akatsuki better. He could pass on his knowledge of the various Akatsuki members' abilities and weaknesses. Naruto, with his natural determination and Itachi's training, might develop new forms of the Rasengan or even learn how to use genjutsu more effectively, something he was not good at before.
One possible plot could be that Itachi, seeing Naruto's potential and his importance for the future of the Hidden Leaf, decides to secretly train him. Itachi might teach Naruto advanced jutsu, especially those related to chakra control and unique Sharingan - inspired techniques. Naruto, under Itachi's tutelage, would grow not only in power but also in his understanding of the ninja world's complex politics and the Uchiha clan's history.
The plot might involve Itachi training Naruto as a way to make amends for his past actions against the Hidden Leaf. Itachi could see Naruto as the key to bringing peace between the Uchiha and the village. So, he imparts his wisdom, combat skills, and strategic thinking to Naruto. Naruto, in turn, uses this new - found knowledge to unite the village further and face threats from outside forces more capably.
The relationship between Naruto and Fem Itachi could be a very interesting aspect. They might form a strong bond similar to a master - apprentice relationship in traditional martial arts. Fem Itachi could share her own experiences and wisdom with Naruto, which could help Naruto better understand the world of shinobi, including the Uchiha clan and their secrets.
Well, it could be that Itachi trains Naruto to better control his chakra. Maybe Itachi sees potential in Naruto to bring peace to the ninja world and decides to pass on his unique skills like the Sharingan's insights on combat.
One aspect of the plot could be Naruto's struggle to control the new power. The Godlike Sharingan is a powerful and potentially dangerous ability. Naruto might initially have a hard time adjusting to seeing the world through the Sharingan's perspective. Itachi would then have to guide him through this process. Also, they could face enemies who are after the power of the Godlike Sharingan that Naruto now has, leading to intense battles where Naruto has to use his new skills and the knowledge Itachi has imparted to him.
In the fanfiction, Naruto could also develop new strategies for fighting. Pein is a strategic mastermind, and under his training, Naruto might learn how to better analyze his opponents, anticipate their moves, and come up with more effective battle plans. This could give him an edge in future battles against powerful enemies.
In this fanfiction scenario, Kurenai could also help Naruto with his emotional control. Naruto has a strong will but sometimes his emotions can get the better of him. Kurenai, with her calm and collected nature, could teach Naruto how to stay focused and in control during intense situations. For example, she could use her own experiences to show Naruto how to channel his emotions into strength rather than letting them cloud his judgment. This would not only improve his combat abilities but also his decision - making skills.
One possible plot could be that Shisui imparts his unique Sharingan - related skills to Naruto. For example, he might teach Naruto how to predict opponents' moves better, just like how the Sharingan can analyze the flow of chakra and movements. This would give Naruto an edge in battles, especially against strong opponents who rely on speed and deception.
In this fanfiction, perhaps Hiruzen realizes Naruto's potential much earlier and decides to train him privately. He might take Naruto on secret missions to build his experience and confidence. This would not only strengthen Naruto's skills but also their bond, which could have a huge impact on the village's future.
The plot might revolve around Naruto being in a strange new world (the RWBY world) and having to adapt quickly. He starts his training with the RWBY team. They first assess his skills and find that his ability to create clones could be really useful. So they start training him in more coordinated attacks using his clones. At the same time, Naruto is learning about Aura from them. As the story progresses, he becomes a part of their team and they all go on adventures together, fighting villains and Grimm, with Naruto using a blend of his ninja skills and RWBY - trained abilities.
Well, one possibility could be that Zetsu imparts some unique and dark jutsu to Naruto. Maybe Naruto starts to learn stealth and subterfuge skills from Zetsu, which are different from what he learned at the ninja academy. This could lead to Naruto having an edge in certain battles where traditional ninja skills aren't enough.
One possible plot could be that Naruto learns new jutsu from Asuma. Asuma might teach Naruto his unique wind - style jutsu, which could enhance Naruto's combat abilities. Naruto could also learn about leadership and strategy from Asuma, as Asuma was a respected leader in the Hidden Leaf. This training could make Naruto a more well - rounded shinobi.
