His relationships might change. For example, if he wished for something that affected the entire ninja world, people's perception of him could shift. Some might see him as a savior even more than they already do, while others might be jealous or afraid of his newfound influence.
His power level would likely increase significantly. If he wished for enhanced ninja abilities, he could become even stronger than he already is. This would make him an even more formidable opponent in battles.
His life would become a lot busier. Taking care of a baby is no easy feat. He'd have to balance his ninja duties with looking after the baby. For example, he might have to cut short his training sessions or decline some missions at first.
His confidence would probably soar. Knowing he has his parents, who are likely strong ninjas, supporting him would make him feel more secure. He might become a bit less reckless as he now has people who care about him deeply and he wouldn't want to worry them.
Well, a genie could offer Hermione the ability to master all magic spells instantly. This would make her an even more formidable force in the fight against the Dark Arts. It might also lead to her being able to develop new spells or defenses that could turn the tide in the wizarding war much faster. So the plot would shift from a more gradual battle of wits and power to a quicker resolution with Hermione's new - found all - powerful magic.
If the book contains powerful jutsu techniques, Naruto's combat abilities will improve. He might learn new ways to use his chakra or combine his existing jutsus in unexpected ways.
It would change the combat dynamics a great deal. Guns are much more powerful in terms of long - range attacks compared to traditional ninja weapons. This would mean that strategies for battles, both in the village and against enemies, would need to be rethought. For instance, the importance of cover and stealth would increase significantly.
If the weapon is a chakra - enhancing tool, it will boost Naruto's existing jutsu. For example, his Rasengan could become more powerful, being able to break through stronger defenses.
It would likely make him question his identity a great deal. He might start to wonder about his biological parents and what traits he got from them. This could lead to a whole new self - discovery journey in the fanfiction.
He might become more confident. Having Excalibur would give him a new sense of power and purpose. He could be more assertive in his actions and decisions.
Naruto's life would change drastically. He would have to adapt his living space to accommodate the baby. His daily routine would include things like feeding, changing diapers, and putting the baby to sleep. Also, he would be more cautious in battles because he now has someone depending on him at home.
It can also make him more empathetic. If he learns about the hardships his ancestors faced, he might better understand the struggles of others. Let's say his heritage reveals that his clan was persecuted. He would then be more likely to stand up for those who are being mistreated in the present. He would grow from a brash, somewhat naive ninja into a more well - rounded and wiser one.
