Well, one interesting aspect could be the exploration of different character relationships in unique scenarios. For example, how characters might interact in post - war situations that weren't fully explored in the original work. Another aspect could be the character development. Writers might take minor characters and give them more in - depth backstories and growth arcs.
The interesting part could also be in the creativity of the plots. Since it's fanfiction, writers can break free from the constraints of the original plot. They can introduce new villains or challenges for the heroes. For instance, a story where the heroes have to deal with a mysterious disease that only affects those with superpowers. This can add a whole new layer of drama and suspense to the boku no hero universe.
One interesting aspect is the power mash - up. For example, seeing how Naruto's jutsu would compare to the quirks in Boku no Hero Academia. It's really cool to imagine Naruto's Rasengan against a powerful quirk - based attack.
Another aspect is the creativity in world - building. Fanfic writers may expand on the existing world of 'Boku no Hero Academia' in the 'lawless' fanfic. They might create new locations, powers, or social structures that are different from the canon. This gives readers a fresh perspective on the familiar world and characters.
One interesting aspect is the character interaction. You get to see how the idols from 'idolmaster' might interact with the heroes from 'boku no hero'. It can create really unique and unexpected dynamics.
The unique quirk concept. Izuku with a light quirk offers a fresh take on his character. It allows for different power - based storylines compared to his original quirk in the canon.
Another idea is a fanfiction where the quirks in Boku no Hero are somehow combined with the chakra system in Naruto. Maybe a character has a quirk that allows them to manipulate chakra in unique ways. This could lead to all sorts of new abilities and storylines.
A cool fanfiction concept could be to have a character lose their quirk and then have to find a new way to be a hero. This would show their determination and resourcefulness. Or, you could write about a new villain who has a quirk that specifically targets the heroes' weaknesses, and how the heroes would have to work together to overcome this threat.
One idea could be creating an OC with a unique quirk that has a drawback they have to constantly overcome. For example, a quirk that allows them to fly but only for a very short time before they need a long recharge. Another idea is to make an OC who is from a different country and has to adapt to the hero society in Japan. They could bring in different cultural perspectives on heroism.
You could also write a fanfic about a time - travel plot. A character goes back in time to prevent a major disaster that happened in the 'boku no hero' world. They have to figure out how to change the past without completely disrupting the future, and along the way, they interact with younger versions of the beloved characters.
One interesting Chisaki fanfiction could be about his backstory before he turned to the dark side. It might explore his relationships with his family or early experiences that led him to develop his extreme beliefs. Another could be a redemption arc fanfiction, where he is given a chance to change and make amends for his actions in the series.
One idea could be Batman somehow getting transported to the Boku no Hero Academia universe. He could use his detective skills and gadgets to help the heroes there. For example, he might be able to analyze the quirks in a way the local heroes haven't thought of before.
