In a fanfiction that gives them new powers or abilities, most of class 1a would be intrigued. Sero might be immediately thinking of how to use those new powers in combat. However, if the new powers are too outlandish or don't fit their characters at all, there could be some pushback. Jiro might be critical and say that it doesn't make sense for her character to have such a random power that has no connection to her music - based quirk.
Well, for Class 1a watching a My Hero Academia fanfic, Mina would be the one who gets really into it and starts discussing it with everyone. She'd be all excited, sharing her thoughts on the cool quirks and relationships in the fanfic. Iida, on the other hand, might be a bit more critical. He'd be thinking about whether the fanfic follows the proper 'rules' of their world and if it has any educational value.
Then there are those like Izuku Midoriya. He might study the fanfiction from a different perspective. Since he's always analyzing quirks and hero strategies, he could look at how the authors in fanfiction have reimagined the characters' quirks and relationships. He might even get some inspiration from it for his own hero analysis notebooks.
Some characters like Tsuyu would be quite level - headed in their reactions. She might simply take the fanfiction as an interesting take on the War Arc. If it has some inaccuracies, she might just shrug it off as creative license. But for characters like Mineta, he could be all over the place. He might be excited if he's shown as more heroic than he actually was in the War Arc, or he could be sulking if he's made to look like a fool.
The heroes in MHA like All Might might view Dabi fanfiction with a sense of concern. All Might has always been about justice and the greater good. He might see Dabi fanfictions as a sign of how some people are attracted to the darker side of the hero - villain dynamic. He could worry that it might influence younger fans in the wrong way. However, villains in MHA might have different reactions. Shigaraki could see Dabi fanfictions as a way to understand how the public perceives Dabi and use that knowledge to his advantage in his evil plans.
I'm not sure exactly what you're asking. If you mean whether Class 1 - A in 'My Hero Academia' could be depicted as watching fanfiction in fan - made stories, it's possible. Fanfiction often takes creative liberties with the existing characters and their actions.
Perhaps Class A would be quite intrigued when watching 'My Hero Academia' fanfiction. They could see how fans outside their universe view their powers, relationships, and adventures. It might even inspire them in some ways.
In a comical fanfiction, most of the characters would enjoy it to some extent. Sans and Papyrus would be great additions to a comical story, and they would probably laugh along with the funny parts. Frisk, depending on how they are portrayed in the fanfiction, would either be the source of the comedy or be reacting to the absurd situations. In a more serious and political - themed fanfiction about the Underground's society, Asgore and Toriel would have deep thoughts. They might discuss among themselves how the fanfiction's view of their leadership and the society they built compares to their own intentions.
For the teachers in My Hero Academia, like Aizawa, he would probably be indifferent to most ships fanfiction. But if there were ships that involved his students in inappropriate or unethical ways in the fanfiction, he would be very concerned. Otherwise, he would just see it as another strange aspect of the fans' creativity and leave it at that.
Well, some characters might be shocked. For example, Deku would probably be very concerned about how he's portrayed in the fanfiction. He might be a bit embarrassed if it shows his more vulnerable moments during the War Arc. Bakugo, on the other hand, could be angry if the fanfiction doesn't show his strength accurately. He's all about being seen as powerful, so any misrepresentation might tick him off.
Well, some of the characters might be really excited. Deku, for example, would probably be super interested in the different powers and hero concepts in Marvel fanfiction. He might take notes on how Marvel heroes use their powers and try to find ways to apply similar ideas to his own hero journey.
