One common theme is the combination of powers. Since it's a crossover of two power - based universes, stories often explore how Marvel powers and My Hero Academia quirks can work together or against each other.
Another theme is the adaptation of Marvel characters to the My Hero Academia world. For example, how would Iron Man fit into the hero society of My Hero Academia? This includes dealing with things like hero rankings and the different social structures. Also, friendship and teamwork are big themes, just like in the original series. Characters from both universes have to learn to work together to face common threats.
The exploration of new identities is also a theme. When Marvel characters enter the My Hero Academia world, they may have to adapt their identities. For instance, Captain America might have to find a new way to represent his values in a world with different cultural and social norms. And there's often a theme of self - discovery as characters figure out how their powers can be used in this new and different universe.
Another theme is the idea of heroism. Both shows revolve around heroes. Fanfictions might focus on how Ben 10, with his alien forms, would be perceived as a hero in the 'Boku no Hero Academia' world, or vice versa. For example, a fanfic could show Ben 10 using his powers to save UA students from a new threat. It also delves into what it really means to be a hero in different contexts.
A common theme is power. Both Naruto and 'boku no hero academia' deal with characters having unique powers. So, in fanfiction, it's often about how the characters' powers interact or compare. For example, Naruto's chakra control compared to the quirk control in 'boku no hero academia'.
One common theme is mentorship. Teachers in these fanfictions often take on the role of guiding students, like how they can better control their quirks. Another theme is the teachers' own backstories. Many fanfictions explore what made the teachers become educators in the first place.
One common theme is friendship evolving into something more. For example, two female characters who start as comrades in hero training might gradually realize they have romantic feelings for each other. Another theme is the struggle against society's expectations. In the 'Boku no Hero Academia' world, heroes have certain images to uphold, and a lesbian relationship might face challenges from the public or the hero community.
One common theme is friendship. Just like in the original series, the pets and their owners or the pets among themselves form strong bonds of friendship. For example, a dog might be extremely loyal to its hero owner and help them in times of need.
One common theme is the exploration of Stain's sense of justice. Since he has a very distinct view on what makes a true hero, fanfictions often delve into this concept, comparing it with the more mainstream ideas of heroism in the 'boku no hero academia' universe.
One of the main themes is Nejire's self - discovery. Fanfictions often show her learning more about herself, her strengths, and her weaknesses. Adventure is also common. Nejire going on various quests or missions, whether it's to save someone or to uncover a mystery. And then there's the theme of teamwork. Nejire working together with other heroes to achieve a common goal is a popular aspect in these fanfictions.
One common theme is cooperation. Since the world of 'boku no hero academia' has heroes and police, a lot of fanfictions explore how they can work together. For example, they might team up to take down a powerful villain. Another theme is the struggle for recognition. The police sometimes get overshadowed by the heroes, so some fanfictions focus on their fight to be seen as important.
One common theme is her struggle with her size - both the advantages and disadvantages. Since she can grow very large, fanfictions often explore how she manages in different situations like in tight spaces or when she needs to be stealthy.
One common theme is identity confusion. When the characters' personalities are swapped, they often struggle with who they are now. Another theme is the impact on relationships. Since their personalities are different, their interactions with others change significantly.
