Uraraka might feel more confident if she saw fanfiction where she was portrayed as a strong and capable hero. Usually, she doubts her own abilities sometimes due to her lack of flashy powers. Seeing positive portrayals of herself in fanfiction could boost her self - esteem and make her believe more in her own strength and potential.
For Todoroki, if he saw fanfiction that delved into his family issues in a new way, it could make him more self - reflective. He might start to think about his past and his relationship with his father from different angles, which could potentially lead to him having a more nuanced view of himself and his place in his family.
On the other hand, Bakugo might be enraged. He's a prideful character and if the fanfiction misrepresents him or shows him in a way he doesn't like, he could get really angry. He might even go on a rant about how inaccurate it is compared to his real self and his ideals of heroism. Also, if the fanfiction portrays him as weak, that would definitely set him off.
Well, some might be really intrigued. Deku, for example, would probably be super excited and start analyzing the different character relationships and power dynamics in the fanfiction, comparing them to what he knows from Naruto. He'd be taking notes in his head, thinking about how these concepts could apply to his own world and his journey to become a great hero.
They might start to see new possibilities for themselves. If the fanfiction shows a character achieving something they hadn't thought of in the original story, it could inspire them to think they can do more.
Some characters might be amused. For example, Denki Kaminari would probably find the wild and creative stories about his electric powers really cool and get a good laugh out of them. He's the type who enjoys a bit of fun and absurdity.
There are those who would be critical. Characters like Iida might analyze the fanfic for its accuracy in terms of the My Hero Academia universe's rules and ethics. If there are any inaccuracies, he might be quick to point them out.
The overall atmosphere in the hero school could become more chaotic or creative. Students might start discussing the fanfictions they've read, and some might even start writing their own based on their classmates. This could lead to a whole new form of creativity and bonding among the students, but also some rivalries if they don't agree on how the characters should be portrayed in the fanfictions.
Some of them could be confused. The settings and concepts in Spider - Man fanfiction might not align with what they know. Bakugo might scoff at first, thinking Spider - Man's powers are not as 'powerful' as his own explosion quirk. But as he reads more, he might start to respect the different ways Spider - Man uses his abilities to fight crime.
Some might gain new perspectives on themselves. For instance, if a character is usually seen as a tough - guy, like Zaeed, and the fanfiction shows him in a more vulnerable moment, he might start to question if he really hides his softer side too much.
Harry might gain a new perspective on his own heroism. He could see how others view him as this super - heroic figure and might feel a bit pressured to live up to those expectations even more. Or he could also realize that he doesn't have to be this perfect hero all the time as the fanfiction might have some versions of him that are more flawed.
They might be really intrigued. The Avengers are used to their own world of superpowers, but My Hero Academia has a whole different set of quirks and characters. They could be impressed by the creativity of the fanfiction writers in combining the two universes, or they might find some of the concepts in the fanfiction really strange compared to what they're used to.
