Well, in some ways it might make him more ruthless. Hidan is a brutal character, so Naruto could pick up some of his no - nonsense attitude towards fighting. He might become less hesitant in battle.
Naruto's training with Hidan in the fanfiction could potentially change his view on the value of life. Since Hidan has a rather unique and somewhat callous view on it. This could lead Naruto to reevaluate his own beliefs and become more strategic in combat, using Hidan - like tactics to outwit his enemies.
In the fanfiction, if Naruto is trained by Hidan, it could have a profound impact on his chakra control. Hidan has his own strange and powerful techniques. Naruto might learn to manipulate his chakra in new and unorthodox ways. This could also affect his physical abilities, making him faster and stronger as he adapts to Hidan's training methods. Maybe he'll even develop some new jutsu inspired by what he learns from Hidan.
Ash's training could make him more determined. He has a new purpose now, which is to show those who betrayed him that they made a mistake. This determination could be seen in his more aggressive training regime and his eagerness to take on tougher opponents. He might also become more observant. Through intense training, he learns to pick up on small details in battles and in the behavior of others, which helps him avoid future betrayals.
Naruto's training would likely become more intense. He might focus on mastering new jutsus like the Rasengan variations. He could also train in stealth and strategy more, as those are important for a Chunin. For example, he could practice sneaking up on opponents and setting up traps.
It also improves Naruto's skills a great deal. He becomes better at combat and using his ninja techniques. For example, his Rasengan might be more powerful or more easily controllable after Iruka's training. Moreover, Naruto's confidence grows under Iruka's guidance. He no longer doubts himself as much and is more willing to take on challenges.
After the training trip in fanfiction, Naruto typically experiences a great transformation. His combat abilities are enhanced, which makes him more formidable in battles. He might start to think more strategically, planning his moves in a fight rather than relying solely on brute force. Additionally, his social skills could improve. He could communicate more effectively with others, be it his friends, his sensei, or even strangers. This new - found confidence and improved communication might lead to stronger bonds within the ninja community. His growth in all these aspects often makes him a more well - rounded and respected character in the fanfiction world.
Naruto's abilities would transform significantly. Yoda's training would likely focus on his mental discipline. This could lead to Naruto having better control over his emotions during battles, which in turn would make his attacks more calculated. His ninjutsu could gain a new level of power as he incorporates some of Yoda's teachings about energy manipulation. Also, his ability to adapt to new situations would be sharpened, just like a Jedi has to be ready for any situation.
Kakashi's training might make Naruto more strategic. For example, instead of just relying on brute force with his Rasengan, he could start using it in combination with feints and misdirections. If Kakashi teaches him how to read an opponent's movements better, Naruto can time his attacks more precisely.
He becomes more in tune with nature. Living in the woods, he learns to respect the environment and its power. This new - found respect might translate into his ninja abilities, making him more powerful when using nature - based jutsu.
His relationships would be very different. His friends might be scared of him at first. For example, Sakura, who's used to the normal Naruto, would be shocked to see him acting like Hidan. His relationship with Sasuke could also change drastically. Sasuke might see Naruto as more of a threat now that he has Hidan - like qualities.
The training by death would likely toughen Naruto up both physically and mentally. He'd probably have a darker, more determined edge to his character. He might be more solitary in his training, spending more time alone to master the skills death has taught him. This could make him seem a bit more distant to his friends initially, but in the long run, it would make him a stronger and more reliable ally.
Naruto becomes more self - reliant. Anko's training often involves solo tasks and challenges. So Naruto learns to rely on his own skills and instincts more, rather than always looking for backup from his friends. For example, he might learn to scout an area alone or set traps without help.
