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.
If the My Hero Academia characters were to react to Spy x Family fanfiction, it would be quite a spectacle. Momo Yaoyorozu could be impressed by the creative plots in the fanfiction. She might admire how the Spy x Family world is built with its own set of rules and characters. Kirishima would likely be excited by the action scenes. He'd be all about the times when Loid has to fight or use his spy skills. And Mineta? Well, he might have some inappropriate thoughts, but we'll just ignore that and focus on the more positive reactions of the other characters.
Well, Bakugo might scoff at first. He'd probably think Batman is too brooding and not as straightforward as he likes his heroes. But then as he reads more of the fanfiction, he might grudgingly admit that Batman's detective skills are cool. Deku, on the other hand, would be super interested. He'd be analyzing every move Batman makes in the fanfiction, taking notes in his head about Batman's strategies and how they could be applied in his own hero work. Uraraka would be more focused on the relationships in the fanfiction. She'd be all 'aww' at the cute moments and feel for the characters when they're in trouble.
Another scenario could be the characters reacting to different versions of themselves from alternate universes. They might be shocked to see how different they could be in terms of personality or appearance. For instance, Midoriya seeing a version of himself who is a villain. This would lead to a lot of self - reflection and internal conflict among the characters.
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.
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.
Well, I think some of the MHA characters would be really confused. For example, Midoriya might be a bit bewildered by the different superpower concepts in the MCU fanfiction. He's used to his own world's Quirks, and suddenly seeing things like the Infinity Stones and Asgardian magic would be a lot to take in.
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.
Perhaps in the fanfic, there could be a villain who is trying to steal the cutie marks of the ponies in the MLP world and use their power for evil in the My Hero Academia world. The heroes from both universes would then have to team up. Deku could use his One For All to protect the ponies, while the ponies could use their friendship magic to support the heroes in combat.
Shigaraki would likely be disgusted if the fanfic made him seem weak or less of a threat. He'd probably scratch at his neck in irritation. Dabi would be dismissive. He'd think fanfics are just a waste of time and not worthy of his attention. Toga, though, might be intrigued. If the fanfic had a lot of blood and gore in it, or if it focused on her relationships in an interesting way, she could be really into it.
