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.
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 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.
Mina. She has a very energetic and positive personality. She's always up for new and fun things, so she would likely be the most into the fanfic, enjoying all the creative ideas and new takes on their world and characters.
One plot could be that Class 1A watches an alternate version of their own battles. They get to see how different decisions could have changed the outcome. It's interesting because they can learn from their 'alternate selves' and maybe improve their own skills in the real world.
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.
Fanfiction.net could also be a good place. There are many different stories in the My Hero Academia category. However, the search function might not be as refined as AO3. You'll have to do a bit more sifting through the results, but it's possible to find fanfictions about Class 1A watching something in the My Hero Academia universe.
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.
RWBY as a whole might find it a fun and different way to experience the My Hero Academia world. They could have group discussions about the fanfictions they've read. For example, they might debate about which fan - created quirk is the most interesting or which character in the fanfiction is the best representation of the original My Hero Academia characters. It could also lead to them thinking about how their own world could be re - imagined in fanfictions by others.
If the My Hero Academia characters react to fanfic, Ochaco might find it really exciting. She could be all giggly about being part of a story someone created. Kirishima would probably be super positive. He'd be like 'That's so manly!' no matter what the fanfic was about. As for Aizawa, he'd likely be more critical. He'd be looking for things like if the characterizations were consistent with how he knows the students, and if not, he'd just roll his eyes and go back to his sleeping bag.
