Another possibility in fanfiction is that they could be in a team - up situation more often. Given Izuku's determination and Pixie Bob's skills, they could make a formidable team. They might work together on rescue missions or fighting against powerful villains. Their combined efforts could lead to some interesting storylines, such as Izuku learning from Pixie Bob's earth - based powers and incorporating some of her strategies into his own fighting style.
There could also be a more serious - minded interaction. In the face of a great threat, Izuku and Pixie Bob might need to work together closely. They would communicate effectively, with Izuku using his strategic mind and Pixie Bob her combat experience. Their interaction would be focused on the mission at hand, like protecting civilians or taking down a dangerous villain.
In fanfiction, their relationship could develop through a common enemy. Suppose a new, powerful villain emerges who threatens both Toga's goals as a villain (in her own twisted way) and Izuku's mission to protect. They might be forced to team up against this foe. During their time together, they would learn about each other's strengths and weaknesses, and this could lead to a deeper understanding and a change in their relationship.
In fanfiction, they might go on joint missions together outside of school. During these missions, they face various challenges that force them to trust each other completely. For instance, when they are up against a powerful villain, Izuku might be in a tight spot and Shoto has to use his quirks precisely to save him. This kind of life - or - death situation would strengthen their relationship.
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.
In fanfiction, Izuku's fight against Muscular is often intense. Izuku usually has to dig deep into his newfound powers. His strategic thinking comes into play. He might analyze Muscular's brute strength and find ways to counter it, like using his speed and agility to dodge attacks and then land precise blows.
One possible plot could be that Izuku discovers Rei's hidden strength. Maybe Rei has some untapped quirk potential that Izuku, with his analytical mind, helps her realize. They could team up to face a new threat in the My Hero Academia world that requires both of their unique skills and experiences.
In the fanfiction, perhaps Stain trains Izuku because he believes Izuku has the purity of heart to use power in a way that Stain deems correct. Stain could teach Izuku how to analyze opponents better, which would enhance Izuku's ability to strategize in battles. Izuku might then start to question the current hero ranking system during his training. He could grow to be a hero who is more focused on the essence of heroism rather than just fame and recognition, which would make him stand out among his peers and also cause some friction with the more traditional heroes and hero agencies.
Maybe the fanfiction could focus on Eri's growth under Izuku's care. She starts to see herself as a normal girl with a powerful quirk, not just a tool. Izuku helps her with her schoolwork, they cook together, and he tells her stories about All Might. As time passes, Eri becomes more confident and starts to think about how she can use her quirk to help others, just like Izuku does. She might even start to train to become a hero herself one day.
Izuku could develop his own unique fighting style. He combines his knowledge of hero strategies and his physical abilities. Maybe he invents gadgets like Batman, which give him an edge in battles against quirk - users. This would make him stand out as a badass hero in the fanfiction world.
Well, at first, the yandere could start as a normal acquaintance. Maybe she's just a fan of Izuku's heroics. But then, as she gets closer, her possessive feelings start to emerge. For instance, she might notice how Izuku is always around other people and feel left out, which then turns into jealousy. This jealousy gradually grows into more extreme yandere behavior.
