Goku's kind - hearted personality would likely make him approach the Saiyans with an open mind. He wouldn't immediately start a fight unless they threatened Earth. His love for a good fight might also lead him to spar with the Saiyans to test his strength against his own kind.
Goku's naivete could play a role. He might be too trusting of the Saiyans at first, not realizing their true intentions. But his strong sense of justice would kick in if they started to cause trouble. His positive attitude could also have an impact on the Saiyans, making them question their own more aggressive natures.
Goku's personality is all about growth and self - improvement. When he meets the Saiyans, he might see it as an opportunity to better himself. He would be curious about their ways and powers. His laid - back nature could defuse tense situations. For example, if the Saiyans are angry or aggressive, Goku might just laugh it off and offer to have a friendly match, which could change the whole dynamic of the encounter.
It could strain their relationship. Chichi might become more distant from Goku, feeling that he doesn't care enough about her safety. For example, if Goku hurts her during a fight on Earth that he brought to their home, she may start to question whether she can trust him to keep their family safe.
If Goku becomes more introverted, the story could change a great deal. His relationships with his friends and family might become more strained as he withdraws from them. For example, he might stop going to Bulma's parties or training with Vegeta as often.
When Goku is reborn as Naruto, his personality could shift in several ways. His naivete might be toned down a bit as he has to adapt to the more nuanced world of Naruto. He may become more empathetic towards the villagers' plights since Naruto has his own backstory of being an outcast. However, his love for challenges and growth in power would still be there, but now it would be more intertwined with Naruto's goals of protecting the village and achieving peace in the ninja world.
Well, Goku's new - found intelligence can sometimes be a bit of a surprise to his friends. At first, they might be a bit skeptical or even a little intimidated. But as they see how he uses it to help them, it can bring them closer. For example, if he uses his smarts to figure out how to get to a new training ground that's really beneficial for everyone. His relationship with Vegeta could also change. Instead of just being rivals in strength, they could start to have more intellectual battles or discussions about strategy.
It could strain their relationship. Goku might start to avoid ChiChi if he's mad at her. For instance, he could spend more time training alone in the mountains or with his friends rather than at home with ChiChi.
Goku's godlike power might make his time travel more precise. Normal time travel in the Dragon Ball universe can be a bit haphazard, but with his godly energy, he could target specific moments more accurately. For instance, he could arrive at the exact second he wants to in the past or future.
Naruto's positive and energetic personality means he'd be very active in taking care of the baby. He'd always be on the move, trying different things to make the baby happy.
His upbringing in Atlantis might make Percy more in - tune with the ancient and mystical side of the ocean. He would grow up surrounded by Atlantean lore and history. This could give him a sense of wisdom and mystery that he wouldn't have if he was raised on the surface. He might be more solemn and less likely to engage in the typical teenage banter that he does in the original stories.
Naruto's outgoing personality can draw Shino out of his shell. Since Naruto is always eager to make friends and include others, he would constantly try to engage Shino in conversations and activities. This would make Shino, who is usually quiet, more open and involved in their friendship.
