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.
Aquaman would likely be intrigued by the otherworldly settings and creatures in Infinity War. He might think about how the underwater world he rules could be affected if something like the events in the movie occurred. Green Lantern, if included in the Justice League for this scenario, would be concerned about the scope of power Thanos wields and how the Lantern Corps could handle such a threat.
Darkseid would be a great main villain. He's already a powerful and well - known foe in the DC universe. He could be the one who starts collecting the Infinity Stones - like items to gain ultimate power and rule over all universes. His army could also be involved, making it a large - scale war for the Justice League.
The plot could involve the Justice League facing off against Thanos. Maybe Superman tries to take on Thanos one - on - one at first, but realizes he needs the whole team. Batman could be strategizing on how to get the Infinity Stones away from Thanos. Wonder Woman could be leading the charge in the battle scenes, using her strength and skills. And Flash could be using his speed to either steal the stones or disrupt Thanos' attacks.
Perhaps in the fanfiction, the Infinity War concept causes some members of the Justice League to turn on each other. Maybe the power of the Infinity Stones - like objects corrupts some of them, like if Flash gets too tempted by the power of speed - enhancing stones and starts causing chaos instead of helping. Then the rest of the team has to figure out how to stop their former ally and also the external threats.
They might be really surprised. Some of them could find it funny to see how fans imagine their adventures and relationships. For example, Superman might be amused by the creative ways fans write about his powers and his interactions with Lois Lane in the fan - made stories.
There might be. It's not uncommon for fanfiction to blend different universes. In such a fanfiction, the Justice League members, like Superman or Batman, could be watching Naruto and having various reactions. Superman might be impressed by the strong will of the ninja characters, while Batman could be analyzing their combat strategies. However, it may not be easy to find, but with a good search on relevant fanfiction platforms, you might get lucky.
Well, if the Justice League were watching Infinity War in a fanfic, it could be really interesting. Aquaman might be amazed at the underwater scenes in Infinity War and make comments about how his own underwater world compares. The Flash would probably be cracking jokes about how slow some of the characters seem compared to his speed. And Cyborg could be interested in the technology shown in the movie.
I think Flash himself would be really interested. After all, it's about him. He'd be curious to see how the writer of the fanfiction portrays his character, his powers, and his relationships with the other members of the Justice League.
They might be quite amused. The Justice League members, with their own complex backstories and powers, would see different interpretations of the Arrow universe in the fanfiction. Some might find it interesting to see how fans envision the crossovers or alternate storylines that could involve Arrow characters.
