The story could focus on Izuku becoming a hero - support figure. Instead of being on the front lines, he could use his intelligence to develop new technologies or strategies for heroes. This would be a different path from the traditional hero - becoming storyline.
Maybe he teams up with villains in an attempt to reform them. Since he doesn't want to be a hero in the usual sense, he might believe that changing the villains from the inside is a better way to create a more harmonious society. This would lead to a very unique and controversial storyline.
The story might explore Izuku's journey to find a new identity outside of the hero world. He could travel the world, learning about different cultures and ways of life, and use that knowledge to advocate for a more inclusive and understanding society, rather than one based solely on the hero - villain dichotomy.
One reason could be fear. The life of a hero is full of danger. Izuku might have seen the toll it takes on heroes, like All Might's weakened state. He could be afraid of getting seriously injured or even dying. Another reason might be self - doubt. Despite his initial dreams, he may have come to believe that he doesn't have what it takes to be a great hero, in terms of both physical and mental strength.
In some fanfictions, their relationship might develop more quickly. For example, All Might could reveal his true form to Izuku much earlier, leading to a deeper bond right from the start. This could make Izuku more determined to prove himself worthy. In other cases, their relationship could be strained. Maybe Izuku starts to doubt All Might's methods and they have a falling out, only to reconcile later when they realize they both have the same goal.
Another possibility is that he joins a different hero school. Maybe there's a smaller, more specialized school that focuses on a particular aspect of heroism that UA doesn't. For example, a school that specializes in rescue operations could be a great fit for Izuku's empathetic nature.
The Hero Killer, on the other hand, has a more radical ideology. He thinks that many so - called heroes are false, only in it for fame or money. In fanfictions, his actions of targeting heroes he deems unworthy are a clear manifestation of his beliefs. His ideology challenges Izuku's in a way that forces Izuku to re - evaluate what it really means to be a hero.
Izuku might be more confident earlier. Without as much time spent in self - doubt, he could project a more positive and assertive attitude.

In fanfiction, Izuku's character could be developed by giving him a different quirk origin story. This new origin could make him more mysterious. Bakugou, on the other hand, could be developed by having him take on a mentorship role for some younger students. This would force him to be more patient and understanding, which is different from his usual brash self.
Maybe Naruto teams up with some non - ninja characters. Together, they could come up with new ways to solve problems in the village that don't require ninja skills. As a result, he gradually changes the view of the village towards non - ninja activities, which is a significant development in the fanfiction.
In this fanfiction, Female Izuku might face different challenges due to her gender. For example, she could face more discrimination in the hero world which is male - dominated in the original. This would force her to be more assertive and prove herself in a different way than Canon Izuku. Also, her relationship with All Might as an adopted daughter would bring out different emotional aspects. She might be more guarded or more open depending on how she interprets her new family situation, which is different from Canon Izuku's relationship with All Might as a mentor.
In these fanfictions, Izuku often develops more confidence in his relationships. For example, he may start off shy around the girls in his harem but gradually become more assertive. This is because the support and love from his harem give him an extra boost.
