The Flash might initially be in denial. He's used to Batman always having a plan and his death would be a huge shock. He would then turn his speed into a tool for investigation, trying to find out exactly what happened. Green Lantern could feel a sense of loss but also be spurred into action, using his ring to try and prevent future tragedies like Batman's death. He might create constructs in Batman's memory to inspire the team.
Some might be shocked. For instance, Batman is often portrayed in very different ways in fanfiction compared to his 'canon' self. Superman might raise an eyebrow at a fanfic where Batman is overly emotional. Others like the Flash might be really into it, finding the different takes on Batman's character and his adventures exciting.
Batman could become more of an anti - hero. He might start working against the Justice League's interests, thinking that they have wronged him. He would use his skills and resources to expose any flaws in the League's operations and undermine their public image.
Yes, there are. For example, in some of the Justice League crossovers, they have significant interactions. These crossovers often show how they contribute to the team dynamic, with Wonder Woman being a powerful force and Batman being the brains behind many strategies.
One interesting story could be them teaming up to take on a powerful supervillain like Darkseid. Their combined skills, with Wonder Woman's strength and combat expertise and Batman's strategic mind and gadgets, would make for an epic battle.
Some of them might be amused. They could find the different takes on their characters and stories quite entertaining. For example, Superman might chuckle at a fanfic that has him in a comical situation.
I really like 'Batman: Shadows in the League'. In this fanfic, Batman has to deal with a secret threat that is undermining the Justice League from within. It shows his detective skills as he uncovers the mystery. The characterizations are on point, especially how Batman interacts with Superman in a more tense situation than usual.
Well, Batman brings a unique set of skills. He's a brilliant detective. In fanfiction, his detective skills can be used to solve complex mysteries that the Justice League might face. For example, when dealing with a villain who leaves no obvious clues, Batman can analyze the situation and find the hidden patterns. Also, his strategic mind is crucial. He can plan out battle strategies that the Justice League can follow to defeat powerful enemies.
He'd probably be confused at first. Naruto is used to being among friends and comrades. But then, his determination would kick in. He'd likely try to talk to them, to understand why they think he's a threat.
