Naruto's personality would be a complex mix. On one hand, he might become more reserved due to Vader's influence. But on the other hand, his natural inclination towards goodness might cause him to constantly struggle against Vader's darker teachings. He could be a much more conflicted individual, with his usually open - hearted and friendly personality warped by the dark environment he was raised in. He might be more secretive and less trusting of others as well.
If Naruto was raised by Darth Vader, his personality would change significantly. He would no longer be the Naruto we know from the original series. The carefree, fun - loving Naruto would be replaced by a more somber and intense character. He would have to learn to suppress his emotions, as Vader would likely teach him that emotions are a weakness. However, Naruto's inborn sense of justice might still shine through, leading to internal conflicts within him as he tries to reconcile Vader's teachings with his own moral compass.
His personality might become more brooding. With Darth Vader's influence, Naruto could lose some of his naivete and become more cautious.
His personality could become darker. Darth Vader's influence might make Naruto more brooding and less of the optimistic character he is. He could start to value power more than friendship at times.
Naruto might become more secretive. Growing up in the Snake Clan, which is often associated with secrecy and hidden motives, he could pick up on their ways of not revealing too much about himself or his plans. For instance, instead of being as open and brash as in the original series, he would be more guarded in his conversations.
If Naruto was raised by Darth Vader in fanfiction, Naruto would likely grow up with a very different view of power. Instead of the ninja way of protecting the village, he might be more focused on galactic domination. However, his kind heart might still lead him to question Vader's more evil actions. He could end up being a very conflicted character, caught between the light and dark sides of the Force and his ninja values.
Naruto could become more intimidating. His natural exuberance would be tempered by the imposing nature of Darth Vader's suit. However, he'd probably find a way to still show his kind heart. Maybe he'd use the suit to scare off enemies at first, but then when they least expect it, show his true Naruto self and offer them a chance to change. He'd have to balance the new - found power of the suit's appearance with his own desire to be a hero in his own way.
Harry's personality would be greatly influenced. He would be more polished in his behavior, as Narcissa would demand propriety. He might be less likely to take risks without thinking, as Narcissa would have instilled in him a sense of caution. His sense of loyalty would be more complex. Instead of the straightforward loyalty he has in the original story, it could be divided between Narcissa's family values and his own sense of right and wrong. Also, he may have a more aristocratic air about him, with a refined way of speaking and interacting with others.
In this fanfiction scenario, Harry Potter's story would take a very dark turn. With Darth Vader as his guardian, Harry would be exposed to a world of power and control from a young age. He might not develop the same sense of justice and fairness as in the original story. Instead of fighting against Voldemort to protect the innocent, he could be more interested in ruling over the wizarding world. His magic might also be influenced by Vader's teachings, perhaps becoming more aggressive and less about helping others. His identity as a wizard would be overshadowed by his Vader - influenced upbringing, making him more of an outcast in the traditional wizarding society.
Naruto's personality might still shine through even as an Arrancar. He's always been determined and kind - hearted. However, he could become a bit more solitary at first as he adjusts to his new form and powers. The Arrancar nature might make him more cautious in some ways, but his basic values of friendship and protecting the weak would remain. He might also develop a bit of an edge, as Arrancars are often seen as more menacing, but it would be a surface change. Deep down, he'd still be the Naruto who wants to bring peace and joy to his village.
He could become more protective. Since Kiva's powers are powerful, Naruto might feel a greater sense of responsibility to protect his village and friends. He might also be more secretive about his new powers, at least until he fully understands them. And his sense of humor might change a bit, becoming a bit darker or more sarcastic as he gets used to his new identity as someone with Kiva - like abilities.
In the 'naruto is like darth vader fanfiction', their journey of self - discovery could be seen as similar. Naruto has to constantly figure out his place in the ninja world and how to control his power. Darth Vader is on a journey of self - discovery too, as he grapples with his identity as Anakin Skywalker and his role as Darth Vader. They also have a sense of isolation in some ways. Naruto often feels alone in his struggles, and Darth Vader is isolated in his dark armor, cut off from his former self and many human connections.
