You can develop characters by putting them in difficult situations. For instance, if a shy character is stuck with a very outgoing one, they might be forced to come out of their shell. The outgoing character could encourage the shy one to be more assertive.
You can also develop characters by showing their adaptability. When they are stuck together in an unfamiliar situation, how do they use their quirks in new ways? A character who has a flying quirk might have to use it to reach something high up in a closed - in space. This shows their resourcefulness and can add new layers to their character.
You can develop characters in the dorms by showing their daily routines. For example, how they study, train, or relax in the dorm environment. This can reveal their personalities, like if a character is really strict about their study schedule, it shows their discipline. Another way is through interactions with roommates. If a character is always arguing with their roommate, it might show they're a bit hot - headed or have different values.
One plot idea could be that the heroes and villains get stuck in an alternate dimension together. They have to put aside their differences to find a way out. Maybe they discover a common enemy within this new place.
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.
It could develop in a more comical way. Maybe they are forced to work on a school project together. Denki is constantly goofing off and Kyouka has to keep him in line. But as they work through the project, they start to find common interests. Denki discovers he likes the type of music Kyouka listens to and Kyouka realizes Denki has a hidden talent for something other than just using his quirk. This new - found understanding brings them closer.
You can also combine different concepts. Maybe Izuku has a quirk that is a mix of telekinesis and heat generation. He could move objects with his mind while also heating them up, creating a powerful offensive and defensive ability. This would require him to train hard to control both aspects of his quirk effectively.
Writers often give Froppy more depth by exploring her backstory further. For example, they might show how she grew up with her quirk and the challenges she faced in a more detailed way. With Deku, they might focus on his mental state during different battles and how he interacts with Froppy. They could write about how Deku's admiration for Froppy's unique abilities affects his own growth as a hero.
Their relationship can develop through shared experiences. For example, if they face a common enemy together, they'll learn to trust each other more. Deku might rely on Melissa's technical expertise, and Melissa will see Deku's heroic side up close, which could lead to admiration and a deeper connection.
The relationship might develop if Toga decides to give up her villainous ways. Uraraka could be the one to inspire her to change. Uraraka's kindness and positive attitude could gradually wear down Toga's defenses. They could start by having small conversations, and as Toga becomes more open, they could become friends. Toga could then learn from Uraraka how to be part of society in a normal way.
Their relationship could develop through shared experiences. For instance, if they both participate in a hero training exercise, they might start to understand each other's strengths and weaknesses better. This could lead to them having more respect for one another and a closer bond.
Their relationship can develop through shared experiences. For example, if they go on a mission together. Deku's heroic nature and Melissa's intelligence can complement each other. They might start as friends, but as they rely on each other more, feelings can grow. Like when Deku saves Melissa from a villain, she starts to see him in a new light, not just as a hero but as someone she could care for deeply.
