Well, one way it could be different is if All Might was more hesitant in passing on One For All. This would create a lot of tension between them as Izuku is eager to become a hero. Izuku might then start to look for other ways to gain power, which could lead to a very different dynamic in their relationship. Another aspect could be if All Might was more involved in Izuku's day - to - day life at UA. He could be like a strict father figure, which would also shape their relationship in a unique way compared to the original story.
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.
They could both develop their teamwork skills. In fanfiction, they might be put in various dangerous situations that require them to rely on each other. Izuku learns to better incorporate Melissa's support items into his fighting style, and Melissa learns how to adjust her items based on Izuku's needs and fighting style at the moment. This back - and - forth development makes their characters more well - rounded.
Well, if All Might and Inko got together, Izuku would likely be overjoyed. He idolizes All Might, and having him as a father - figure would be a dream come true. It could also give Izuku more direct access to All Might's knowledge and training, which would make him an even more powerful hero in training.
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 many fanfictions, Izuku's character development often focuses on his confidence. Tsuyu's presence can be a stabilizing force for him. For example, when he hesitates during a fight, Tsuyu's straightforward and practical nature might encourage him to act. As for Tsuyu, she may develop her leadership skills. If she and Izuku are in a team - up situation frequently, she might learn to be more assertive from Izuku's determination.
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.
A cool storyline could be that All Might and Izuku get trapped in a parallel universe where heroics are completely different. They have to find a way to get back while also learning from this new world. Another idea is that Izuku discovers a dark secret about All Might's past that makes him question their relationship but ultimately strengthens their bond as they work through it. Also, a story where All Might and Izuku team up with some of the villains to fight a greater evil that threatens the entire hero - villain ecosystem.
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.
In many fanfictions, Izuku and the Hero Killer have a complex relationship. Sometimes, Izuku might be portrayed as trying to understand the Hero Killer's motives, which are often misconstrued but rooted in a desire for 'true' heroism. This can lead to some really interesting character development for Izuku as he grapples with his own ideas of heroism in the face of such a radical view.
Their relationship in the fanfiction can be seen as a symbol of hope and inspiration. All Might represents the pinnacle of heroism, and by choosing Deku as his successor, he gives Deku the chance to fulfill his dreams. Meanwhile, Deku's determination and growth also inspire All Might to keep believing in the future of heroism, even in the face of his own declining power.
