If Naruto had Tobi's personality, his goal of bringing Sasuke back to the village would be very different. He would not be as sincere and straightforward about it. He might play with Sasuke's emotions more, trying to make Sasuke come back on his terms rather than for the sake of friendship. This could make the whole Sasuke - Naruto dynamic more complex and full of intrigue.
His goal of becoming Hokage might take a different turn. Instead of being the hero that everyone looks up to, he could be a more shadowy figure. He might use his influence as Hokage in a more manipulative way, like Tobi uses his power. So his idea of what it means to be Hokage could be completely warped.
Regarding his overall goal of peace in the ninja world, Naruto with Tobi's personality would approach it in a unique way. He might not believe in the same kind of unity that he used to. Instead, he could try to control the different ninja villages through more underhanded means, like creating false alliances or using blackmail. This would lead to a very different kind of ninja world order than what Naruto originally envisioned.
Naruto's energetic personality would likely make him a very active pilot. He'd be constantly looking for ways to engage the enemy and wouldn't be afraid to take risks.
Naruto's positive and determined personality would make him a great doctor. He never gives up, so he would keep trying different treatments for his patients even when faced with difficult cases. His friendly nature would also put patients at ease, which is important for their recovery.
If Naruto and Sasuke switched personalities, their goals would shift. Naruto, now with Sasuke's personality, would likely focus more on personal power and revenge. His goal might become to take down those who wronged him or his village in a more cold - hearted way. Sasuke, with Naruto's personality, would probably aim to bring peace and unity not just to the Leaf Village but to the whole ninja world through friendship and understanding.
The emerald could help Naruto achieve his goal of becoming Hokage more quickly. Its power might make him more respected among the villagers, as they see him as someone who can control such a powerful object.
His positive personality would make him an excellent servant. He's very determined, so he'd do whatever it takes to fulfill his duties. His friendly nature would also mean he could get along well with his master and other servants.
Anko's a bit of a rebel in some ways. This could encourage Naruto to think outside the box when it comes to ninja tactics. He wouldn't be so bound by the traditional ways. For example, he might come up with new ways to combine his Rasengan with other jutsu based on Anko's unorthodox thinking. Also, her somewhat edgy personality could make Naruto more street - smart and less naive in the ninja world.
One way is to tie his alternate personality to a hidden power or a unique kekkei genkai. Maybe this hidden part of him has abilities that no one suspects. This can lead to him being a more complex and unpredictable character in the fanfiction. As he discovers and learns to control this aspect of himself, it can drive the plot forward, especially if other characters start to notice the changes in him.
Naruto's determination would play a big role. He'd never give up on building the spaceship, no matter how many setbacks he faces. His optimistic nature would keep his team's morale high. For example, if they run out of materials, he'd be the one to say 'We'll find a way!'. His impulsiveness might sometimes lead to quick but not fully thought - out decisions, like starting construction before having a complete plan.
Naruto's energetic and positive personality would make the hotel a lively place. His enthusiasm would be contagious, and guests would feel welcome. He would probably be very hands - on in the management, making sure every guest has a great experience.
Naruto's most prominent personality trait is his determination. As Kage of another village, this would drive him to improve the village no matter the obstacles. For example, if it's a village with a weak economy, he'd find ways to boost it. He wouldn't be deterred by the naysayers.
