He'd develop by learning about the different types of magic and how they compare to his ninja abilities. His experiences in the Naruto world, like dealing with loss and fighting for his village, would shape how he approaches the challenges in the wizarding world. For example, he might be more fearless in the face of dark wizards because he's already faced so many tough foes in his past life.
Naruto's character would also develop through his relationships. He'd make friends with Harry, Hermione, and Ron, and learn from them. At the same time, he'd teach them things too. His growth would be a combination of his ninja instincts and the new magical knowledge he gains. He might even start to see magic as another form of chakra manipulation and find new ways to combine the two, which would further develop his character as a unique individual in the Harry Potter world.
Naruto's character would likely become more refined. With the influence of fem Harry Potter, he might be more diplomatic. He could learn from her how to approach problems with a different mindset, not just brute force. For instance, he may start using his words more effectively before jumping into a fight.
Korra's development would probably involve her coming to terms with the new rules and values of the Naruto universe. The concept of honor among ninjas and the importance of clans would be new to her. She might initially resist these ideas but eventually incorporate some of them into her own moral code, making her a more complex and well - rounded character.
She might be more in touch with her emotions. As a girl, Naruto could be more likely to show vulnerability, which was something she hid as a boy. This could lead to deeper relationships with her friends as they see a different side of her.
His character would probably become more complex. He'd have to adapt to a world without wizards at first. He might start off being cautious, but as he discovers the powers and politics of the Twilight world, he'd grow bolder. He could use his intelligence and magic to his advantage.
Naruto's character would likely become more stoic. Vergil is known for his calm and collected demeanor, so Naruto might start to suppress his more exuberant emotions. He could become more calculating in battles, thinking several steps ahead like Vergil does when facing his enemies.
Naruto might become more serious. Deadshot is a very serious and focused character. So Naruto could lose some of his goofy and carefree nature and become more calculating in his actions.
Naruto might become more cautious. Dealing with the Daleks, who are extremely dangerous and unpredictable, would force him to think before acting. His normal brashness might be toned down a bit.
Naruto's character would likely become more calm and introspective. He'd focus more on inner peace rather than external battles.
In the fanfiction where Harry is adopted by Naruto, their relationship would be complex yet fascinating. Initially, Harry might feel out of place in Naruto's world. But Naruto, being the friendly and empathetic person he is, would do everything he could to make Harry feel welcome. As they get to know each other better, they'd realize they have a lot in common. Both have faced great adversity in their lives. Naruto's experiences with the Akatsuki could be compared to Harry's battles with Voldemort. They'd support each other in their respective struggles. Harry would come to admire Naruto's unwavering determination, and Naruto would respect Harry's magical abilities. This would lead to a strong and multi - faceted relationship, where they not only see each other as family but also as comrades in a much larger fight against evil.
He would become more adaptable. Middle - earth is so different from the wizarding world, so he'd have to learn new ways. His character might become more in tune with nature like the elves in Middle - earth.
