They could be shocked. Some of the fanfiction might have really wild ideas that they've never thought of.
The reactions would be diverse. The Flash characters have their own personalities and values. Those who are more open - minded, like Wally West, might embrace the fanfiction and even look forward to reading more. But some more serious characters, like Joe West, might be a bit skeptical at first. They would need to adjust to this new form of storytelling about them. And if there are fanfictions that involve their personal traumas or secrets, they might be a bit uncomfortable, but overall, it would be a unique experience for them to see how fans perceive them.
They could be interested because it gives them a different perspective on their own story. It's like looking at themselves from the outside in.
Some characters might become closer if they share the same feelings about the fanfiction. For example, if two characters both find a certain part of the fanfiction hilarious, they could bond over that.
At first, Flash might be a bit confused. His world is so different from the world of Glee. But as he listens more, he'd start to appreciate the artistry. The emotions expressed through the music would touch him. He might even start to see parallels between the unity and teamwork in the Glee club and the teamwork he has with his own allies in fighting crime. He could then become a big supporter of the Glee club, using his powers to spread the word about their amazing music.
Well, it could lead to a variety of reactions. Some characters might be annoyed if the fanfiction misrepresents them. However, others like Cisco could use it as inspiration for new ideas in their own adventures. They might also be surprised at the depth of the fans' understanding and love for their world.
The characters would have a range of reactions. Barry (Flash) would probably be very protective. He's a hero who helps people, and Kara is his friend. He'd likely offer his speed and any resources he has to keep her safe. Kara's friends on Supergirl's side, like Alex, would be shocked at first but then become very supportive. They might start planning how to protect Kara and the baby from all the threats they face in their world.
The other characters' reactions could be quite diverse. Flash's friends might be supportive at first, thinking it's just a new hobby of his. But as his pretense continues, they might start to get annoyed. The bullies in Flash's clique could see it as a weakness and start to pick on him. Meanwhile, the people who are actually Spider - Man fans might be outraged that Flash is faking it just for attention. They could confront him and expose his falsehood, leading to a big drama in the story.
The more perceptive friends like Batman might notice the change in their dynamic right away. He'd probably keep an eye on them to make sure it doesn't interfere with their work as heroes. Others like Aqualad might be a bit surprised at first, but then be happy for them. He'd understand that their relationship could bring out the best in both of them.
They might find it really interesting. Some might be amused by the different interpretations of their characters in the fanfiction. For example, Cisco could be excited to see how the writer envisions his tech in new and creative ways.
Well, perhaps the characters start to discuss among themselves about how the fanfiction portrays them. They could be either amused or a bit offended. For example, if a character is depicted as being cowardly in the fanfiction when they see themselves as brave, they would likely have a strong reaction. They might even try to figure out who wrote it and why they were written that way.
Some might laugh. They could find the humorous takes in the fanfiction really entertaining. Maybe there are some comical interpretations of their actions or dialogues that they themselves didn't expect.
