The 'team - up against a greater evil' trope is very common. In this, all the heroes from My Hero Academia, JLA, and Avengers come together to fight a powerful villain that no single group could defeat on their own. It often involves some initial misunderstandings or rivalries between the groups that are eventually overcome. Also, the 'training montage' trope can be fun. A character from one universe might train with heroes from another universe to learn new skills or better control their powers.
A good way is to focus on a particular theme. Let's say the theme is 'adaptation'. The characters from My Hero Academia, who are used to a world where having quirks is normal, have to adapt to the more 'classic' superhero worlds of JLA and Avengers. Maybe some of the Avengers or JLA members are skeptical about these new 'quirky' heroes at first. This can lead to character development as they learn to trust and work together. It also allows for exploring the differences in how heroes are perceived in each universe.
One popular trope is the 'Quirkless Hero' where a character without a quirk manages to become a hero in some way. It's often used to show the power of determination and creativity. Another is 'Villain Redemption', where a villain character from the series gets a chance to turn good and change their ways.
The 'family reunion' trope is quite popular too. Given his connection to the Todoroki family, fanfictions often feature scenarios where Dabi has to face his family members again. This can lead to intense emotional moments and complex character interactions in the fan - made stories.
Some popular tropes in boko no hero academia fanfiction include the mentor - mentee relationship. This can be between established heroes and up - and - coming students. The time - travel trope is also seen, where characters go back in time to change events. There are also stories that focus on the backstories of minor characters, fleshing them out and giving them more depth than what is shown in the original anime or manga.
One popular trope is the 'Quirkless Hero' where a character without a quirk manages to become a hero through sheer determination and intelligence. Another is 'Villain Redemption', where a villain decides to change their ways. 'Time Travel' is also quite common, with characters going back in time to fix things in the My Hero Academia universe.
One popular trope is the 'character swap'. For example, a character from My Hero Academia might take on the role or abilities of an Overwatch character and vice versa. Another is the 'team - up' trope, where heroes from both universes come together to fight a common enemy. It's exciting to see how the different powers and skills interact.
One popular trope is the 'Quirk - based Magic'. In these fanfictions, quirks are often combined with magic elements, creating unique and interesting power systems. Another is 'Alternate Universe' where the characters are placed in a completely different setting, like a medieval fantasy world. And 'Character Crossovers' are also common, for example, a character from My Hero Academia crossing over with a character from a different anime in a fantasy scenario.
Another common trope is the main character having memories of their past life. This often leads to them having a different perspective on the events in the MHA universe. They might use their knowledge of the original story to their advantage, like knowing the weaknesses of certain villains or the secrets of powerful heroes.
Well, a common trope is the alternate universe exploration. In My Hero Academia dimension fanfiction, writers often take characters into different versions of the MHA universe. There's also the redemption arc trope for villains. They might find themselves in a different dimension where they get a chance to change their ways. Time - travel is another trope, where characters go back or forward in time within the MHA dimension.
One popular trope is the 'outsider' hero. In My Hero Academia monster fanfiction, a character who is part - monster might be seen as an outsider in a world of 'normal' heroes. They have to struggle not only with fighting villains but also with acceptance. Another trope is the 'hidden power' where the monster - like abilities are initially not fully understood or controlled by the character but turn out to be extremely powerful. For example, a character might have a monstrous form that gives them super strength and endurance but they first have to learn how to transform at will.
