To develop their relationship in a fanfic, it could start with a simple conversation. Maybe Izuku asks Momo for advice on how to improve his academic performance, since she is one of the top students. Momo is initially a bit formal, but as they talk more, she realizes Izuku's genuine eagerness to learn. This leads to more interactions. They could then be paired for a rescue mission where they have to rely on each other's strengths. Izuku's physical strength and Momo's ability to create necessary tools make them a great team. This experience cements their friendship, and from there, it could potentially develop into something more romantic as they continue to grow and support each other.
The relationship can be developed through shared experiences. For example, if they are both part of a rescue mission. During the mission, they can rely on each other's strengths. Deku's physical courage and Momo's intellectual capabilities can combine to save lives. This mutual reliance can start to build a deeper connection.
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 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.
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.
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 a 'My Hero Academia Jirou x Momo fanfic', their relationship often showcases a unique dynamic. They are both students at UA High School. Jirou is known for her music - based quirk and her somewhat aloof personality, while Momo has a creation quirk and is more of a leader - type. Their interactions in fanfics can range from study buddies to something more romantic. Fanfic writers might explore how their different quirks could complement each other in various situations, like in combat training or during a rescue mission. It's interesting to see how their individual personalities mesh in these fictional stories.
I've also read 'The Unlikely Duo'. This fanfic takes a different approach. It starts with Izuku and Momo being paired up for a project that has nothing to do with hero work. They initially clash because of their different personalities, but as they get to know each other better, they start to realize they have a lot in common and a relationship slowly blossoms.
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.
One plot idea could be that Izuku and Momo are paired up for a special training mission. They have to learn to combine their quirks in new and unexpected ways. For example, Izuku's super strength could be used to enhance Momo's creation of large and complex structures. Another idea is a story where they both get trapped in an alternate dimension and have to rely on each other to find a way back. They face various challenges that test not only their quirks but also their friendship and trust in each other.
Another possibility is that they could be in a romantic relationship in fanfiction. Momo's calm and intelligent nature might be attracted to Todoroki's strong and stoic personality. They could support each other through the challenges of being heroes - in - training, and their relationship could develop as they share their hopes and fears with each other.
