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.
In fanfics about Shigaraki from Boku no Hero Academia, he is often depicted with more complex backstories. Some fanfics explore his childhood traumas in greater detail, which gives readers a deeper understanding of his motives. For example, they might expand on how his family's neglect led to his current state of mind.
One great plot twist could be that Shigaraki has a hidden noble intention behind his actions. Maybe he's trying to expose a deeper corruption in the hero society that no one else sees. It makes readers re - evaluate his character.
In certain fanfictions, Shigaraki's redemption is tied to his past. Maybe he discovers some long - forgotten memories that make him understand his true self and that he doesn't have to be a villain. He then starts to use his power for good instead of destruction.
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.
Shigaraki is a very popular character in the Boku no Hero Academia fanfic community. He is often the focus of many fan - created stories because of his complex and mysterious nature.
There's also 'Growth Together'. This fanfic shows how Deku and Todoroki support each other during tough times at UA. They face challenges not only from villains but also from within the school. Their relationship develops as they help each other overcome these obstacles.
One idea for a Deku's Quirk fanfiction could be exploring what would happen if Deku's quirk manifested in a different way. For example, instead of having to gradually control One For All, he suddenly has full mastery from the start. This could lead to a very different story arc where he is immediately seen as a top - tier hero - in - training, causing envy and admiration in equal measure among his classmates.
