One common theme is the exploration of different character relationships. For example, how a female Katsuki would interact with Deku in a more romantic or platonic way. Another theme could be her journey in the hero academy, facing different challenges and growing as a character, much like in the original story but with a female - centered perspective.
Some fanfics may center around a female Katsuki's backstory. This could include her family life, her early experiences with her quirk, and how those things shaped her into the character she is in the fanfic. Additionally, friendship themes are common, such as her relationships with other female characters in the 'My Hero Academia' universe, and how they support each other through various difficulties.
Many fanfictions also focus on his internal struggles. His insecurities beneath his tough exterior are explored. This vulnerability, when paired with his outward bravado, can create an interesting dynamic. The way he copes with pressure, especially in the highly competitive world of heroes in the My Hero Academia universe, can be a theme that authors use to make him a more complex and alluring character in their fan - created stories.
One common theme is empowerment. Since Bakugou is already a strong character, in the female version, it often focuses on her breaking gender barriers in the hero world. For example, she might face discrimination at first but then prove herself to be even better than male heroes.
Self - discovery is also seen often. The female characters in these fanfics, while interacting with Todoroki, also go through their own journey of self - discovery. They might learn more about their own powers, their place in the hero world, and how they can grow as individuals in relation to Todoroki's presence in their lives.
One common theme is the exploration of different power systems. Since Naruto has its chakra-based powers and My Hero Academia has quirks, fanfics often explore how these two power systems interact when a female Naruto is involved. For instance, how her ninjutsu might be mistaken for a really powerful quirk.
In these fanfics, the theme of transformation is often present. Female Izuku might transform into a dragon or have dragon - like features, which represents a change in her identity. This ties into the theme of acceptance. Katsuki has to accept this new Izuku, and Izuku has to accept her own new identity. Also, the theme of adventure is common. They often go on adventures together, facing challenges that test their relationship and their individual strengths.
A common theme is the transformation of their relationship from rivals to lovers. They often start off bickering and competing, but then gradually fall in love.

Power is a common theme. Since Redestro is a powerful character, many fanfics explore how he wields his power, whether for good or bad. Another theme is leadership, as he is a leader in the story. Fanfics often show different aspects of his leadership style.
One common theme is Nejire's growth as a hero. Since she's a character with a lot of potential in the original series, fanfics often explore how she hones her skills.
Overcoming obstacles is another theme. It could be external obstacles like villains who might try to use their relationship against them, or internal ones like self - doubt and fear of rejection. These themes add depth and drama to the gay fanfics set in the 'My Hero Academia' world.
