In this kind of fanfic, other characters would react in diverse ways. All Might's colleagues among the pro - heroes might be supportive. They might offer their own expertise to help Izuku grow. But there could also be some who are jealous of All Might's decision and try to undermine Izuku. Among Izuku's peers, some might be inspired by his new situation. They might work harder to catch up to him. Others might feel left out. And in the public eye, there would be a lot of admiration for All Might's act of adoption. People would have high hopes for Izuku and would be watching his every move. This added pressure could also be a factor in how Izuku develops in the fanfic.
In a fanfic where All Might adopts Izuku, Izuku's life would take a different turn. He'd be part of All Might's family, which means he'd be exposed to a different way of life. All Might could teach him not just about heroics but also about life values. This would shape Izuku into a more well - rounded person. Izuku would also have a stronger support system. When it comes to his quirk, All Might could help him understand and control it better. He might even be able to use All Might's influence to get better equipment for Izuku. All in all, this adoption would enhance Izuku's story in many positive ways.
Others could be really intrigued. They might get caught up in the new storylines and start to wonder what if these things could actually happen in their universe. Like Arnold, he's always open - minded, so he might be really into exploring these new fan - created scenarios.
Some characters would be excited. Imagine if Goku from Dragon Ball saw a fanfic where he had new and even more powerful forms. He'd probably be thrilled to see the creativity of the fans and might even get inspired to train harder in his own world, thinking about all the cool possibilities the fanfic presented.
Some characters could be confused. If the fanfic changes certain aspects of the original story significantly, for example, if it alters the relationships between characters in a way that's different from what they know, they would be at a loss. They may not understand why the writer made such changes. Also, if the fanfic contains some out - of - character moments for them, they might be quite puzzled.
They might laugh at it. Bullies often find things to ridicule, and BTS fanfic, being something that's very dear to the fans, could be an easy target for them.
His friends like Ochaco and Iida would likely be very worried. Ochaco might use her quirk to try and gently float Izuku to safety if possible, while Iida would be all about getting him medical attention as quickly as possible.
Well, Ruby might be really excited. She loves stories and new adventures, so she'd probably be into the action and heroics in the Dekaranger fanfic. Weiss could be a bit more critical, analyzing the writing style and how it compares to the literature she's used to. Blake might see parallels between the Dekaranger's battles and the struggles in her own world, and be quite intrigued. Yang would likely enjoy the fight scenes and cheer on the Dekarangers as if she were at a boxing match.
They might be really surprised. For example, Ruby could be excited to see different versions of herself in the multiverse. She might start thinking about how she could learn from those other selves.
Surprise. They might be surprised to see how fans imagine different scenarios for them. For example, a character from a magical girl anime might be shocked to find a fanfiction where she's suddenly a detective in a noir - style story.
One possible plotline could be Lucifer realizing that Trixie needs a stable family figure and decides to step in as her adoptive father. He then has to deal with the challenges of raising a human child while also being the Devil.
