He might become more confident. Batman is already a confident character, but with Superman's powers, he'd have a new level of assurance. He could take on any threat without hesitation.
Batman could become more arrogant. The sudden acquisition of such great powers might make him think he's invincible. He might start to look down on others who don't have his abilities. However, deep down, his core values of justice would still be there, and he'd probably realize his mistake eventually.
Well, if Batman had Superman's powers, Gotham would be a very different place. He could fly around the city, stopping crimes in an instant. His detective skills combined with super strength and heat vision would make him an almost unbeatable crime - fighter. He might be able to lift entire buildings to rescue people trapped inside. And he could use his super speed to be everywhere at once, ensuring no criminal act goes unnoticed.
In a Naruto - Superman powers fanfic, perhaps Naruto gets some of Superman's powers accidentally. He struggles to control the new powers like heat vision and super speed along with his own ninja abilities. Superman, on the other hand, discovers he can use chakra in a limited way and they both have to figure out how to use these new combinations of powers effectively.
If Batman had Superman powers in fanfiction, he would be an unstoppable force. He could use his detective skills combined with super strength, flight, and heat vision. Gotham would be a much safer place as he could quickly stop crimes across the city without relying on his gadgets as much. He might even be able to take on more global threats, which would be a huge change from his normal focus on Gotham's underworld.
Naruto's personality would become more brooding. He would be less impulsive and more calculating, like Batman. He might not be as openly friendly as he was before, keeping his thoughts and plans more to himself.
He might become more confident, bordering on overconfident at times. With superpowers, he would have a greater sense of invincibility, which could make him a bit more reckless in his actions compared to his non - superpowered self.
One aspect of a Batman - Superman friendship fanfic could be how they overcome their differences. Batman is a dark, brooding vigilante while Superman is the all - American hero. Their friendship might start from a mutual respect for each other's abilities. For example, in a story, they could team up to fight a common enemy that neither could defeat alone. This would force them to rely on each other and learn about the other's strengths and weaknesses.
Well, in a fanfic about Batman and Superman's friendship and fatherhood, they could be depicted as mentors to their sidekicks in a more fatherly way. Batman with Robin and Superman with Superboy perhaps. Their friendship might be tested as they balance their superhero duties and their newfound father - like roles.
Naruto could use his Rasengan with Superman's strength. Imagine the power of a Rasengan thrown with Superman - level force. It would be extremely destructive.
Well, Batman as a kid in fanfiction would have a very different personality. His determination would still be there, but it would be mixed with a child's innocence. He'd be more likely to make mistakes based on inexperience, but also more willing to forgive and forget. His sense of humor might emerge more, as kids tend to find humor in different things. He could also be more vulnerable, which would make his relationships with other characters more complex. For example, his relationship with Alfred would become more of a father - son dynamic, with Alfred having to be more protective and nurturing.
A fanfiction of Batman with Superman powers would be very different from the original stories. In the originals, Batman is vulnerable, which adds a sense of danger and realism. But with Superman powers, he's almost invincible. His relationships with other characters would shift. For example, his partnership with Robin might not be as necessary since he can handle most situations alone. Also, the villains would have to be much stronger or more devious to pose a threat to him. And the stories would likely involve more large - scale, world - saving events rather than the street - level crime - fighting that is typical of Batman.
