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.
If Batman had Superman powers in a fanfic, he'd probably become more isolated. Superman's powers are so great that they can make a person feel alone in the world. Batman, who already has a bit of a loner streak, might struggle even more with human connection. On the plus side, he could protect Gotham from threats that are currently out of his reach, like some of the more powerful supervillains that require superhuman strength to defeat.
In a fanfic where Batman has Superman powers, he could revolutionize crime - fighting. For example, he could use his x - ray vision to see through walls and find hidden criminals or evidence. His super - hearing would allow him to listen in on criminal plans from miles away. However, he would also face new challenges. People might fear him more than they already do because of his increased power. And he'd have to be careful not to let the power go to his head, as it's a slippery slope from hero to tyrant when you have that much power at your fingertips.
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.
One possibility is that the Justice League would be divided. Some members might side with Superman, believing he had a good reason, while others would stand by Batman. This would create a power struggle within the league.
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.
A fanfic about Batman and Catwoman proposing could have different tones. It could be a light - hearted take where they joke around during the proposal. Or it could be a very serious and emotional one. For example, after a big battle where they almost lost each other, Batman realizes he can't live without Catwoman and decides to propose. Catwoman, who has always loved Batman but was afraid of commitment, finally says yes, seeing that he is truly committed to her.
In a fanfic where Batman joins the Joker, it could lead to a really strange and dark alliance. Maybe Batman is trying to understand the Joker's madness from the inside. He might pretend to be on the Joker's side to stop a greater evil that only the Joker seems to know about.
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.
One way is to have them support each other in their father - figure roles. For example, when Superman is away on a mission, Batman could look after Superboy, and vice versa with Robin. Their friendship would be the basis for this trust.
Well, he could be there to offer his expertise. Maybe he wants to train the Titans in new combat techniques. He might also be there to check on a potential threat that the Titans are facing and offer his help in dealing with it.
Well, first of all, Naruto could use his ability to sense chakra to find Superman's weak points. Once he locates them, he could use his wind - style jutsu, like the Rasenshuriken, which is a powerful and cutting - edge attack. He could also use his teleportation - like jutsu, the Flying Thunder God Technique, to quickly get behind Superman and attack him from a blind spot. Superman might try to use his heat vision, but Naruto could use his chakra shield to block it. And if the fanfic allows, Naruto could even gain some new power during the battle, like the power to nullify Superman's super strength, and then land a final, decisive blow.
In some fanfics, Batman might attack Robin due to mind control. For example, if a villain like the Joker manages to get his hands on some new technology or a powerful magic item that allows him to manipulate Batman's mind. Another reason could be a misunderstanding. Maybe Robin was framed for something he didn't do, and Batman, in his haste to seek justice, attacks without fully understanding the situation. It could also be a part of a darker, alternate universe story where the characters' personalities are twisted, and Batman has turned to the dark side for some reason.
