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.
Batman could also be very interested. He's always analyzing things and trying to understand every aspect of his teammates. Watching the Flash fanfiction would give him more insights into the Flash's character, potential weaknesses, and how others view him. He could use this knowledge for future team strategies or just to understand the Flash better on a personal level. And, he might enjoy critiquing the plot and the writing style as well.
The Justice League typically includes well-known heroes like Superman, Batman, Wonder Woman, The Flash, Green Lantern, Aquaman, and others. These characters form the core team.
Well, it could be about the Justice League members sitting down and reacting to the Flash's adventures in the fanfiction. Maybe they laugh at his silly mistakes or are in awe of his heroic deeds in the made - up stories.
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.
The OC's personality can be very distinct. They could be extremely humorous and use that to lighten the mood during tense situations. This would be different from the more serious natures of some of the Justice League members like Batman. Also, they could have a strong moral code that is not exactly the same as the League's, which would lead to interesting discussions and interactions.
Wonder Woman is also very powerful. She has superhuman strength, combat skills, and her Lasso of Truth can force people to tell the truth. Her bracelets can deflect attacks. She is a key member in battles. Well, she comes from an island of powerful Amazons and her powers are a combination of her divine heritage and training.
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.
They might be quite surprised. Some members might find the different interpretations of magic and heroic concepts interesting, while others could be critical of how the Fate world's rules are applied in the fanfiction.
They might be shocked at the alternate versions of themselves and the events in the Injustice fanfiction. It could make them reflect on their own actions and relationships in their own universe.
They might have a range of reactions. Superman could be amused or a bit confused by some of the wilder interpretations of Batman. Wonder Woman might find it interesting to see how fans perceive the Dark Knight's world. Flash might laugh out loud at some of the more comical fanfictions.
Batman would probably be more critical. He'd analyze how the fanfiction portrays his detective skills and his relationship with the other members of the Justice League. He might not like it if the stories make him seem too soft or too brutal, as he has a very specific self - image.
