Superman would likely be impressed yet also a bit competitive. He'd see Goku's strength and might feel the urge to prove himself. Batman would be calculating, taking mental notes on Goku's fighting style. Wonder Woman would admire Goku's tenacity and the way he uses his ki. The Flash would be astounded by Goku's speed, which might even make him a bit envious.
Overall, the Justice League would have a mix of reactions. They would be in awe of Goku's ability to constantly power up. His fighting spirit would inspire them. Some might feel challenged, like Superman, while others, like Batman, would be more interested in learning from Goku. They would also start to question their own limits and how they can grow as heroes after witnessing Goku's incredible feats in combat.
Superman would likely be impressed. He's used to being one of the strongest, but Goku's power levels would make him take notice. Batman would be his usual calculating self, studying Goku's moves for any potential threats or useful techniques. Flash would be excited to see someone who could keep up with his speed in a different way. Aquaman might be a bit more reserved, but still interested in this new kind of fighter from another universe.
Well, if the Justice League were to watch Goku's fight in a fanfiction, they'd probably be in awe. Goku's fighting style is so different from what they're used to. His ki - based attacks and super - speed would be mind - boggling for them. They might start thinking of new strategies for their own battles, inspired by Goku's ability to constantly power up. Also, they could be quite shocked at how Goku can take on incredibly powerful foes almost single - handedly.
The Justice League as a whole would have a diverse range of reactions. Some members like the Flash would be all for it, seeing it as a fun exploration of Batman. Others like Wonder Woman might use it as a way to understand how the public perceives Batman's role in the League. And then there are those like Aquaman who might just shrug it off unless it directly affects his interests. The fanfiction could also potentially create some internal discussions within the League about how they are all portrayed in the public's imagination.
Some of them might laugh. They would see the creative and sometimes out - there ideas that fans come up with in the fanfiction. For example, if there's a fanfic where Oliver Queen teams up with a really strange character from the Arrowverse, it could be quite humorous to them.
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.
They could be looking for self - discovery. By seeing how others write about them, they might gain insights into their own personalities. For instance, Wonder Woman might read fanfiction to see how fans view her role as a female superhero and what kind of challenges they think she should face.
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.
In fanfiction, Goku Black could be incorporated into the Justice League as a sort of experiment. The League, always looking for ways to increase their power and protect the world, might see his abilities as a valuable asset. However, his different moral code and origin from another universe would create a lot of tension. There could be a story arc where the League tries to reform him or at least control his more violent tendencies while using his power to fight against threats that are beyond their normal capabilities.
They would be amazed. The Justice League is used to their own brand of super - powered battles, but Infinity War would show them a whole new level of cosmic warfare. Superman might be the first to jump into action, mentally preparing himself to take on Thanos if he was in that universe.
They'd likely be intrigued. Batman would study it for plot devices and character development. He might use some of the ideas in his own crime - fighting strategies. Superman would probably be entertained, seeing it as a new form of storytelling about a hero. Wonder Woman might view it as a cultural phenomenon and think about how it reflects on modern society's view of heroes.
