When it comes to his relationship with the Justice League, if Batman has new powers like energy projection, it could change the power dynamic. Some members might be jealous or feel threatened by his new abilities, while others would see it as an asset to the team. For instance, Superman might be a bit cautious at first as Batman's new powers could potentially rival his own.
If Batman got superpowers, perhaps he could have the power of flight. This would give him a huge advantage in Gotham. He could quickly reach any crime scene in the city, and also chase down villains who try to escape using airborne vehicles. It would also make his presence more intimidating as he could swoop down on criminals from above.
In some Batman fanfiction, he might have the power of telepathy. This could allow him to read the minds of his enemies, giving him an edge in combat and detective work. For example, he could anticipate the Joker's next move before it even happens.
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.
Sure. In fanfiction, the sky's the limit when it comes to giving powers to characters. Batman might be depicted with the power of flight, which would completely change the way he approaches fighting crime. He could swoop down on criminals from above, much like a bat. Robin could have the power of invisibility. This would make him an excellent spy within the criminal underworld. He could gather information without being detected, giving Batman and him an edge in their fight against evil.
Perhaps he gets a power related to mind control. This would allow him to influence the actions of his enemies or even make them fight among themselves. He could also gain a power that lets him absorb the powers of his defeated foes. So, every time he defeats an enemy, he becomes stronger by adding their powers to his own arsenal.
One common super power in such fanfiction is the ability to teleport short distances. This allows Batman to quickly move around Gotham City, getting to crime scenes or escaping danger in the blink of an eye. It adds an exciting new dimension to his already impressive skills.
Obviously, Dipper is the main character as the title implies. His sister Mabel is often included too. She might react in various ways to Dipper getting powers, like being excited or a bit jealous. Wendy is also a common character. She could be a source of support or a love interest for Dipper in some fanfictions.
In this fanfiction, Robin might get powers as a result of a genetic mutation triggered by a rare chemical. These powers could include enhanced speed and the ability to see in the dark. He initially hides his powers from the team because he's afraid of how they'll react. But when a dangerous situation arises where his powers could be the key to victory, he reveals them and they all work together to defeat the enemy and accept his new status.
