Batman, without a doubt. He has such a rich backstory with his parents' death, his training around the world, and his determination to fight crime in Gotham. Writers can explore his complex personality, his moral code, and how he interacts with other, more super - powered members of the Justice League.
First, think about the reason why Batman would use a gun. Is it a special circumstance? Then, create a plot that builds around this change. For example, a new villain who is immune to his non - lethal weapons. Next, consider how the other Justice League members will react.
A cool concept could be a 'Batman Justice League fanfiction' set in an alternate universe where the League is formed much earlier in history. Batman has to adapt to working with heroes from different time periods and cultures, and they all have to figure out how to use their powers in a world that's not as technologically advanced as their own.
Obviously Batman himself is a key character. Then there could be characters like Catwoman, who has a long - standing relationship with Batman. Wonder Woman could also be part of the harem, given her strong connection to Batman in some storylines. And perhaps Batgirl, as she has a close relationship with Batman in the comics.
Obviously Batman himself is extremely popular. He's the main focus after all. But Superman also features prominently as his counterpart and sometimes rival. Wonder Woman is also a favorite as she often has interesting interactions with Batman, whether it's in combat or in strategic planning within the fanfiction stories.
Obviously, Batman and the members of the Justice League are the main characters. Batman is the Dark Knight, known for his intelligence and combat skills. And then there's Superman, the Man of Steel with super strength and other powers. There's also Wonder Woman, a powerful Amazon warrior.
Batman's sacrifice would likely have a huge impact on the Justice League. It could make them more determined to uphold justice in his memory. They might also become more cautious as they've lost a great strategist.
One interesting storyline could be the Justice League having to deal with a mind - controlled Batman. Maybe some villain manages to take over Batman's mind, and the League has to figure out how to stop him without harming their friend. It would be full of action as they try to outwit Batman's strategic plans while also trying to break the mind control.
One idea could be a story where Batman has to lead the Justice League in a fight against a new, powerful and mysterious villain that can manipulate time. Another could be a fanfiction exploring the relationships within the Justice League when they are stranded on an uninhabited planet and have to rely on each other more than ever.
One idea could be a story where Batman has to lead the Justice League in a fight against a new, powerful villain who can manipulate time. The League members start losing their memories one by one, and Batman has to figure out a way to stop the villain while also restoring his team's memories.
In this type of fanfiction, a plot might be that Batman's harem is formed by various female superheroes or characters associated with the Justice League. The story could explore how their different personalities and powers interact within the harem. For instance, Wonder Woman might bring her Amazonian values and leadership skills, while another character could offer a more tech - savvy or street - smart perspective. And all of this while they are in a relationship with Batman and also working together in the Justice League.
