Well, there would be the boys themselves who are the central characters. They are likely to be curious, brave or perhaps a bit rebellious as they choose to wear tight corsets which is not a common thing for boys to do.
It depends. Some people love Corset Story corsets for their style and fit, but others might have issues with sizing or comfort. It really varies from person to person.
Spiderman has his super strength, agility, and the famous spider - sense. In comparison, MHA characters have a wide variety of quirks. For example, Todoroki has his ice and fire powers. Spiderman's agility might be on par with some of the more acrobatic MHA characters like Sero. But his spider - sense gives him an edge in combat that most MHA characters don't have. However, quirks like All Might's super strength can rival Spiderman's own strength.
Deku is quite popular. His journey to become a great hero can be easily translated into a gaming context, like him leveling up his skills. Bakugo is also a favorite. His brash personality and powerful quirk make for exciting scenarios in fanfictions.
There could also be a theme of transformation. The act of wearing a tight corset can physically and metaphorically change the boys' appearance and perhaps their perception of themselves. This can be explored in terms of how they adapt to this new 'look' and what it means for their relationships with others.
Corsets were mainly used for shaping the body to fit the fashion ideals of different eras. For example, in the 19th century, they were used to create a small - waisted silhouette which was considered very fashionable. Women wore corsets to achieve this look for formal occasions and even in daily wear in some cases.
One common theme is the historical aspect. Corsets have a long history, so works might explore different eras when corsets were in fashion, like the Victorian era. Another theme could be the fashion and design of corsets, including how they were made and the materials used.
Izuku Midoriya is really popular. His journey from being a quirkless boy to a powerful hero - in - training is very inspiring. Katsuki Bakugo is also popular. His explosive personality and strong power make him stand out. And Ochaco Uraraka with her cute appearance and kind heart is liked by many.
Uraraka would probably find it really interesting. She has a positive and curious nature. She'd be excited to see how the changes in backstories affected the relationships between the characters. And she might even share her thoughts about it with her friends in the MHA universe.
Some MHA characters might be really intrigued by Disney fanfiction. For example, Izuku Midoriya would probably be super excited. He loves stories and analyzing different characters' motives, just like he does with heroes. He'd be all about exploring the new worlds and character relationships in the Disney fanfics.
