Well, Naruto is a very open and trusting person. If reborn as Obito, he would have to deal with the fact that Obito was a much more complex and, at times, devious character. He might become more calculating in order to survive in the situations that Obito was in. However, his basic nature of being a hero and wanting to protect people would remain intact. He would use Obito's skills and his own moral compass to navigate the world in a way that would surprise those who knew the original Obito.
His personality would change in several ways. For one, he'd have to be more cautious. Obito was involved in a lot of secretive and dangerous operations. Naruto would have to adapt to this new level of secrecy. Also, he might become more brooding as he tries to understand Obito's darker motives in the original story. But ultimately, his strong belief in friendship and his never - give - up attitude would still be there, and he'd use them to make different choices than Obito did.
Naruto's usually sunny and optimistic personality might become a bit more brooding. Since he's in Obito's body, he might be influenced by the memories of Obito's tragic past. However, he would still try to hold on to his core values of friendship and never giving up.
His personality would be a blend. He would have Kakashi's calmness in high - pressure situations. But at the same time, Naruto's exuberance would peek through at times. For instance, when he's around his friends or when he's really passionate about something. He would be more introverted in general but would still show his Naruto - like enthusiasm on certain occasions.
Obito's influence would likely make Naruto more aware of the darker side of the ninja world. Naruto is usually very optimistic, but with Obito's guidance, he would see the hardships and betrayals that can happen. For example, Naruto might become more cautious in his trust of others.
Naruto's love for his friends and his village would translate into a new form in this rebirth. He might see the people in the Dragon Ball universe as his new family and friends. His outgoing and friendly nature could start to break down the walls of fear that Frieza had created. He would be less likely to immediately resort to violence like the old Frieza, instead trying to talk things out first, but still be ready to fight if necessary to protect those he cares about.
Naruto's personality would be a blend. He'd keep his core values like loyalty and his love for his friends. However, being in Cell's body, he'd have to adapt. He might become more reserved in some ways because Cell wasn't as open as Naruto. But he'd still find ways to show his Naruto - ness, like when it comes to facing challenges head - on and never giving up. He'd also have to handle the power - hungry side of Cell's nature, but he'd probably try to turn it into a drive to protect rather than conquer.
Naruto might become a bit more reserved at first. Since Tsuna's world is different from Naruto's, he'd have to adapt. But his core of being kind - hearted and determined would remain. He might be more cautious as Tsuna initially isn't as bold as Naruto was in his own world.
It could change it a great deal. For one, Obito might not be as much of a villain. His alliance with Naruto could lead to a united front against Madara much earlier. This would mean less destruction and death in the ninja world. Also, Naruto would have a powerful ally who has a deep understanding of the Sharingan and its powers. They could develop new jutsu together, changing the power dynamics in battles.
Naruto might be more brooding and less of the cheerful optimist. Obito's own experiences of loss and his somewhat dark view of the world could rub off on Naruto. He'd be more cautious and less likely to trust people immediately.
If Naruto was raised by Obito, his relationships would take a radical turn. With the villagers, he would be seen as an outsider or even a threat, just like Obito was in a way. His relationship with Sakura would be different too. Without the common experiences in the village, he might not have the same friendly - rival kind of relationship with her. And his relationship with the Akatsuki members could be very different. He might be more inclined to understand their motives or even join them at some point, given Obito's connection to the group. It would create a whole new web of relationships that are far removed from what we saw in the original Naruto story.
He might become more lenient. In the Naruto world, there is a greater emphasis on teamwork and friendship compared to his original world. So, he could gradually soften his strict and solitary ways as he experiences the bonds that the ninjas form.
