Love is also a theme, whether it's platonic or romantic. Their relationship can be seen as a way for them to experience different kinds of love. Additionally, the theme of trust is often explored. They need to build trust in each other, which can be a difficult process considering their initial positions as adversaries.
One common theme is her growth as a hero. Many fanfics focus on how Uraraka overcomes challenges to become a better hero, like improving her quirk control.
Another theme is the idea of seeing beyond appearances. Midoriya, with his empathetic nature, looks past Toga's villainous exterior and tries to understand her. This is often shown as he gets to know the real person behind the blood - thirsty facade that Toga presents to the world.
Another theme is the exploration of their opposing natures. Toga is wild and unpredictable, while Bakugou is more hot - headed but has a strict moral code. Fanfics often play with how these two different personalities interact and either clash or find common ground.
One common theme is the exploration of their dark sides. Both Dabi and Toga have rather dark personalities in the original work, and fanfics often dig deeper into that. For example, how their dark natures might attract or repel each other.
Another theme could be redemption. Some fanfics might have Toga seeking redemption through her relationship with Bakugo. Since Bakugo represents a strong sense of justice, he could be the catalyst for Toga to change for the better.
A third common theme is the power dynamic between them. Dabi has a certain level of power and mystery, and Toga has her unique abilities. Fanfic may play with how these powers interact in different situations, such as in battles together or in protecting each other. This can add an interesting layer to their relationship in the stories.
One common theme is friendship. Writers often explore how their different personalities interact and form a strong bond of friendship. For example, Iida's more serious and rule - abiding nature contrasting with Uraraka's more easy - going and friendly attitude.
Friendship development is also common. They start off as classmates with not much in common, but through various events in the fanfic, they form a bond. It could be through training together or facing a common enemy.
Another theme could be mutual growth. As they interact in the fanfic, they might help each other improve their hero skills. For instance, Midoriya's strategic thinking could inspire Uraraka, and her positive attitude could boost Midoriya when he's feeling down. This theme of growing together as heroes and as people is quite popular in such fanfics.
One common theme is friendship development. They might start off as just classmates but then grow to be really good friends. Another could be about them working together in a mission and learning to trust each other.
