Love and romance can be a theme as well. The SI/OC could fall in love with one of the characters from the original series. It could be a slow - burn relationship with lots of obstacles, like differences in their hero goals or social status within the hero community. This adds a whole new layer of drama to the fanfiction.
The theme of overcoming obstacles is very common. In these fanfictions, the lesbian couple has to overcome various obstacles like discrimination from other students or even some of the teachers. They also have to deal with the challenges of being heroes at the same time. For instance, they might have to hide their relationship while on a joint mission to avoid negative reactions from their teammates. This creates a lot of tension and drama in the story, which is a key part of many of these fanfictions.
One common theme is self - discovery. The OC, being a gamer in a new world like My Hero Academia, often has to figure out their place and abilities. Another theme is power - up. Just like in games, the OC usually gets stronger over time.
Another theme is self - discovery. The grey OC has to figure out who they are and what they stand for. They're not following the typical hero or villain path, so they have to create their own identity. This often involves exploring their powers, their values, and their place in the world of My Hero Academia.
Power and responsibility is also a common theme. Just like in the original 'Boku no Hero Academia', the OC in these fanfictions has to balance his new - found powers with the responsibility of being in a harem. For example, he has to protect his harem members while also using his powers for the greater good. It's a complex dynamic that adds depth to the story.
Love and friendship are also common themes. The fanfics often show how the OC and Todoroki grow closer, whether it's through shared experiences at UA or facing external threats together. Their relationship can start as friends and slowly develop into something more romantic over time.
A lot of these fanfictions also deal with the theme of acceptance. The OCs may have to accept their own feelings for another female character in a world that might not be fully accepting. It could be about coming out or just dealing with internalized homophobia. Additionally, there's often the theme of teamwork. Since My Hero Academia is about heroes, the femslash pairings might be heroes who have to work together and their relationship develops during their heroic deeds.
One common theme is the corruption within the hero society. Your dark OC can be a tool to expose the seedy underbelly of how heroes are really like. Another theme is the struggle between good and evil, but from the perspective of the OC who might not see things in such black - and - white terms. Revenge is also a popular theme. Maybe the OC has a vendetta against a certain hero or the hero system in general.
Another common theme is the idea of a different perspective. Fanfictions may show events from the Hero Killer's point of view, which is different from the typical hero - centered view in the original series. This can make readers see the world of My Hero Academia in a new light, understanding the frustrations and reasons that led the Hero Killer to do what he did. It can also create more complex relationships between characters as they start to understand each other's motives better.
Another theme is identity. The oc has to establish their identity in a world full of pre - existing characters with their own identities. They may struggle with whether to blend in or stand out, like in some fanfictions where the oc tries to hide their true nature at first but then realizes they need to embrace it to make a real impact.
One common theme is self - discovery. The self - inserted character often has to figure out their place in the Uzumaki world. Another theme is friendship, as they usually form bonds with Uzumaki characters.
