He could develop a deeper sense of responsibility. If he wishes for his family's well - being, he'll be more focused on protecting the newfound family situation. For example, he might start teaching his family self - defense techniques so they can better protect themselves when he's not around.
Goku would likely become more content. Knowing his family is taken care of or reunited, he'd have a new - found sense of peace. This might make him less reckless in battles as he has more to lose.
Goku may become more in tune with his emotions. Wishing for his family shows his love and care for them. In the fanfiction, this could lead to him being more expressive about his feelings towards his family, which is a big change from his usually somewhat oblivious self when it comes to emotional matters.
Goku might become more in touch with his Saiyan heritage. His tail was a part of what made him a Saiyan originally, so getting it back could make him more aware of his roots. He could become more aggressive in battle, like how Saiyans are known to be.
When Goku meets his family in fanfiction, his character could develop in terms of his emotional intelligence. He would learn to better express his love and care for his family members. For instance, he might become more patient with his sons' training, understanding that they need more guidance and support rather than just tough challenges. Also, he could become more protective of his family, having seen all the dangers out there in his adventures.
In one scenario, Goku's wish could bring back his Saiyan family. He might get to meet his real parents and learn more about his Saiyan heritage. This could lead to new training methods and a stronger bond within the Saiyan community in the fanfiction world.
If Naruto is trained by Goku in fanfiction, his character would experience significant growth. Naruto is already a determined character, but Goku's training could make him even more so. He would learn to value hard work in a different way. His relationships with his friends might also change as he becomes more self - reliant in his training. Additionally, Naruto's sense of justice could be broadened by Goku's more universal view of protecting the innocent. He would no longer just be focused on his village but on a larger scale of good and evil, making him a more well - rounded and developed character.
His character would become more confident. With Goku's support and the newfound power from being in the Dragon Ball universe, Naruto would have less self - doubt. He'd be more eager to take on challenges.
His social skills might be different. Instead of the somewhat naive Goku we know, he could be more aware of social norms. Bulma could teach him about proper behavior, but at the same time, his Saiyan impulsiveness would still shine through at times. So he might be a strange mix of a well - mannered person in some situations and a wild fighter when provoked.
His character would develop a more strategic side. Beerus is a very strategic fighter, and Goku, being raised by him, would learn to think more before acting in battles. He would also become more aware of the power hierarchy in the universe at a younger age, which could make him more cautious or more ambitious, depending on how you look at it. Additionally, his Saiyan pride might be tempered by Beerus' teachings, making him more of a team player in some ways.
Goku could develop a deeper understanding of the power he wields. The Grand Priest's training would not only focus on physical strength but also on the spiritual aspect of ki. This could lead to Goku having a more profound connection with his Saiyan heritage and the energy that flows within him. He may also become more patient, as the Grand Priest's training methods might be complex and require time to master.
His character could develop in a darker direction. The abandonment could fuel feelings of anger and resentment. He might lash out at those around him, especially if they remind him of his lost family. But on the other hand, this could also be the starting point for a great transformation. If he overcomes these negative emotions, he could become an even stronger and more empathetic person. For example, he might start to help other orphans or those who have been rejected by their families, seeing his own pain in them.
His character may become more independent. Without relying on his family, he has to fend for himself and make his own decisions. This can lead to him being more self - assured. For example, he might be quicker to take risks in battles or in making important choices.
