His view of the world would change. He'd understand that there are greater forces at work and that he has the power to stand up to them. This could lead to him being more proactive in preventing future threats. He may also develop a deeper sense of responsibility for the entire ninja world, not just his village. For example, he might start diplomatic efforts to ensure peace among all ninja nations on a more regular basis.
Naruto's character could become more spiritual. After facing a god, he may start to explore the spiritual side of the ninja world more deeply. He could learn about ancient ninja religions or start to meditate more often to understand the power he has and how to use it for the greater good. He might also become more of a legend, with younger ninjas looking up to him even more, and he'd have to deal with the pressure of being such a powerful and well - known figure.
Naruto could develop a sense of guilt and isolation. Since Itachi was a well - known figure, Naruto might face criticism or be shunned by some for killing him. This would force him to re - evaluate his relationships and his place in the ninja world. He might have to struggle to prove that his actions were for the greater good and find new allies who understand his motives.
Naruto might become more conflicted. With the influence of the Demon God's power, he could question his own values. For example, the power might make him more aggressive in battle, which goes against his usual belief in protecting everyone. He would have to find a balance between using the new power and staying true to himself.
Naruto could also become more determined to avoid such situations in the future. He may work harder on his diplomatic skills or try to understand his enemies better before jumping into a fight. This experience could be a turning point for him, making him grow as a ninja not just in terms of power but also in wisdom and self - understanding.
Naruto's character could develop in a more complex way. Killing is not something he takes lightly, so he might struggle with guilt afterwards. This could make him more somber and less naive. For instance, he might question his own values and what it means to protect the village.
If Naruto kills the villagers, he would lose his innocence. He has always been about protecting and being accepted by the village. Killing them would make him a much darker and more complex character. He might become more of an anti - hero, full of guilt and self - loathing.
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.
Naruto's character development would be complex. He would gain a new sense of purpose. In his ninja world, his goal was to protect his village and become Hokage. Now, he has to protect an entire universe. This would force him to grow in ways he never expected. He would have to learn about different cultures and species in Universe 7. His values would also be tested. For instance, he might have to make tough decisions about sacrificing one planet to save the whole universe, which would be a major shift from his usual 'never - give - up - on - anyone' attitude.
