Well, in a fanfiction where Naruto is trained by Itachi in Sharingan, Naruto would first have to adapt to the new power. Itachi would probably start with the basics of how to activate and control the Sharingan. Since Naruto is used to his own physical and chakra - based training, this would be a challenge. However, with Itachi's guidance, he could master it. Once he does, he could use the Sharingan to analyze his opponents' fighting styles better. For example, he could quickly figure out the weaknesses in an enemy's jutsu and counter them effectively. He could also use the Sharingan's visual prowess to enhance his reaction time during battles.
In this fanfiction, Naruto might gain some unique jutsu skills from Itachi. Itachi is extremely powerful, so he could teach Naruto advanced genjutsu or ways to better control his chakra. For example, Naruto might learn how to quickly break free from strong genjutsu attacks, which would be a great advantage in battles against tough opponents.
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.
Naruto's character development in this fanfiction scenario would be multi - faceted. Firstly, his relationship with Itachi would be a major factor. He'd respect Itachi more and perhaps see him as a mentor. As he trains in the Sharingan, he'd learn discipline in a new way, different from his training with Jiraiya. His interactions with other characters, especially those who are wary of the Sharingan's power, would change. He might have to prove that he can use this power for good. His growth would not only be in terms of combat skills but also in his maturity and how he views the ninja world as a whole.
One way could be through a powerful jutsu gone wrong. Maybe a jutsu that was meant to transfer Itachi's memories to Naruto accidentally transferred his Sharingan as well. In the world of fanfiction, there are often many creative and out - of - the - box explanations.
Naruto's character would develop a new sense of self - confidence. Having the Godlike Sharingan and being trained by Itachi would give him a feeling of being a part of something greater. He would no longer be just the 'loud - mouthed underdog' but a powerful ninja with unique abilities. However, he would also have to deal with the new expectations that come with this power. He might struggle with the idea of whether he is still the same Naruto or if the power has changed him too much. This internal conflict would be an important part of his character development as he tries to find a balance between his old self and the new, more powerful version of himself.
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.
Well, if Naruto was born with the Sharingan in fanfiction, it would be a game - changer. Firstly, his training with Iruka and later Kakashi would be different. Instead of focusing on his own natural chakra and the Rasengan, he could also be trained to master the abilities of the Sharingan. This could potentially make him a much more powerful ninja at a younger age. And in battles, he could use the Sharingan's predictive abilities to dodge attacks more effectively and counter - attack with greater precision.
Well, Naruto would probably become an even more formidable ninja. Batman's skills in strategy, detective work, and various combat techniques could enhance Naruto's abilities. Naruto might learn to approach battles with more stealth and planning, rather than just relying on his brute strength and chakra. He could also pick up some of Batman's gadgets and use them in his own ninja way, like using batarangs as a new type of shuriken.
In this fanfiction scenario, Naruto might gain a whole new set of skills and perspectives. Nagato has powerful jutsu like the Rinnegan abilities. He could teach Naruto more about the nature of chakra on a deeper level. Naruto might also learn different combat strategies that are more in line with Nagato's style of fighting, which could make him an even more formidable opponent.
Well, Naruto would probably become an even more formidable ninja. Batman's strategic mind and combat skills could enhance Naruto's own abilities. He might learn new ways of stealth and planning, making him a more well - rounded fighter in the ninja world.
