Love and romance can also be a theme, although not always in a straightforward way. Sometimes it's a slow - burn romance where they gradually realize their feelings for each other. Additionally, the theme of growth is prevalent. They grow as heroes and as individuals because of their connection. This can include things like improving their combat skills, learning new strategies, and becoming more confident in themselves.
Well, 'United Hearts' is a great one too. In this fanfiction, fem shoto has a unique quirk that complements izuku's in unexpected ways during battles. Their interactions outside of combat are also very well - written, with a slow - burn kind of relationship that builds up over time as they get to know each other better. It's full of action, emotion, and some really cool hero - related scenarios.
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.
One idea could be that Shoto and Izuku have to team up for a special training exercise that goes horribly wrong. They end up in an unknown part of the forest and have to rely on each other's quirks to survive and find their way back. For example, Izuku uses his One For All to climb tall trees to get a better view, while Shoto uses his ice to create shelters at night.
In the comic, Vox and Shoto have a complex relationship that involves both cooperation and conflict. Their personalities and goals clash at times, but also lead to unexpected developments.
Often, there is the theme of inspiration. Deku is very inspiring in the original story, and in fanfiction, he can inspire Shoto to be a better hero. Also, self - discovery. They both are on a journey to discover more about themselves, their powers, and their place in the hero world. In fanfiction, this journey can be elaborated on in different and interesting ways.
