Well, from what we know of the My Hero Academia world, there's no evidence to suggest that they do. Their world is filled with real - life heroics and challenges. Fanfiction is more of an outside - world creation for fans. However, if we were to think creatively, maybe some of the more tech - savvy or curious characters like Mei Hatsume might stumble upon something similar if there was a crossover into a world where fanfiction existed within their universe, but it's really just a fun thought experiment.
Some characters could actually be flattered. They may enjoy seeing how much the fans care about them and their story. However, there could also be characters who are confused by some of the more out - there concepts in fanfiction, like when a character from a different universe is introduced into the My Hero Academia world in a fan - made story. They might wonder how such a thing could be possible within the context of their world.
It's possible. If we consider the idea that the Boku no Hero Academia universe has a concept of our world's fanfiction, then some of the more tech - savvy or curious characters could potentially stumble upon it. Maybe a character like Izuku Midoriya, who is always eager to learn about heroes, might be interested in seeing how fans view the hero world in fanfiction. However, this is all in the realm of creative speculation as the original series doesn't touch on this directly.
They may be either amused or annoyed. It depends on how they are portrayed in the fanfiction. If it's a positive and creative portrayal, they might be amused. But if it's a negative or inaccurate one, they could be annoyed.
AO3 is great for My Hero Academia fanfiction. It allows for detailed tagging, so you can easily find the specific type of story you're interested in, whether it's about a particular character, a certain ship, or a specific plot type. FanFiction.net has a large and active community, so there are always new stories being updated. Wattpad, on the other hand, may have some unique interpretations and crossovers that you might not find elsewhere.
Some characters might be intrigued. For example, Izuku Midoriya would probably be very interested in understanding how the Gamer Sparda powers work. He would see it as a new type of quirk to study and might try to find ways to incorporate the strategies used in the 'game' aspect into his own hero training.
It could be about a hero in the My Hero Academia universe who is disappearing for various reasons, like perhaps a quirk malfunction, a secret mission that requires them to go incognito, or they might be under some sort of threat that is causing them to vanish from the public eye.
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.
To write this fanfiction, start by brainstorming ideas. Maybe you want to create a story where Zenyatta uses his healing abilities to save a hero in My Hero Academia who was critically injured. You should also pay attention to the writing style. Keep it engaging and make sure the dialogue fits the characters. For instance, Zenyatta might speak in a calm and philosophical way, while the My Hero Academia characters have their own distinct voices.
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.
There could be a really interesting fanfiction where Momo from My Hero Academia meets Naruto. Maybe they are in a world where quirks and ninjutsu co - exist. Momo's intelligence and ability to create objects could be paired with Naruto's determination and powerful jutsus. They could go on adventures together, facing villains from both universes.
