They could develop a symbiotic relationship. Maybe Nomu has a power that All Might needs to defeat a greater evil, and in return, All Might helps Nomu to become more than just a mindless weapon. This would require them to trust each other, which is a unique take on their relationship considering their normal opposing natures. Also, the story could explore how their relationship changes as they face different challenges together.
I'm not sure specifically as I haven't read that exact fanfic. But generally, in a USJ (Unforeseen Simulation Joint) rescue fanfic, it might be about characters from class 1 - a and 2 - b rescuing others during some sort of emergency or attack in the USJ. It could involve heroic deeds, character development, and intense action scenes.
Well, in a typical scenario for this kind of fanfic, it could be the leaders or the most skilled students from class 1 - a and 2 - b. For instance, if it's related to a hero - based story, the ones with the most impressive superpowers or combat skills might be the main characters. They would be the ones taking charge of the rescue operation at the USJ and making the crucial decisions.
Definitely some of the well - known characters from class 1 like Izuku Midoriya could be main characters. His determination and unique quirk would play a big role in the story. Also, from class 2, maybe Momo Yaoyorozu. Her intelligence and creation quirk could be very useful in the events that might take place at USJ.
One plot idea could be that characters from class 1 and class 2 team up during an unexpected event at USJ. Maybe there's a new villain who has a special power that disrupts the normal training exercises at USJ. The students from both classes have to combine their different skills and quirks to defeat the villain and save the day.
Well, in such a fanfiction, Izuku might end up in a coma. His friends would be really worried. Ochaco might constantly visit him in the hospital, hoping he wakes up soon. And Bakugo could have a change of heart, realizing he should have been nicer to Izuku all along.
He would likely feel a sense of failure. Since Izuku has such a strong drive to be a hero, being hurt by the Nomu might make him think he's not good enough yet. It could be a big blow to his self - confidence.
One of the most thrilling scenes could be when the villains first make their grand entrance at the USJ. The chaos that ensues as they start attacking the students and teachers creates a lot of tension. Another great scene might be when the main character steps up to face a particularly strong villain, showing their growth and determination.
