The characters in the 'bnha big 3 fanfic' are centered around Mirio, Nejire, and Tamaki. However, depending on the plot of the fanfic, it could also involve villains. Imagine a scenario where the big 3 have to face a powerful villain who has a quirk that specifically targets their weaknesses. This would not only showcase the abilities of the big 3 but also introduce new and exciting elements to the fanfic.
Mustard is, of course, one of the main characters. Depending on the fanfic, other characters from the BnHA series like Deku or Bakugo might also be involved. They could be either in a confrontational relationship with Mustard or in a situation where they are trying to understand him better.
Since it's a fan - made work, the main characters could be a combination of fan - favorites and the author's original creations. For example, if the story is about a secret sky - based society, it could center around a character who is an outcast from that society and some of the well - known Bnha heroes who try to help them. The characters' relationships and how they grow in this unique setting would be an important part of the fanfic.
All Might is frequently a popular character as well. His status as a symbol of peace in the original BNHA can be translated into a powerful and respected figure in the gamer fanfiction world. Maybe he's a high - level mentor - like character that the protagonists look up to and seek advice from in the game - related adventures.
I don't know for sure without more information about the specific novel. But usually in 'bnha' - related works, there are likely to be some interesting new characters with unique quirks.
Obviously, Opbozuku is one of the main characters. Often, his friends and classmates from the BNHA world also play important roles, like Deku, Bakugo, etc. They might be his allies, rivals, or both in the fanfic.
I assume the main characters would still be the ones from the main 'bnha' series, like Izuku Midoriya. He's the protagonist and his journey to become a great hero is central to the story. Bakugo Katsuki would also likely be a main character, with his complex relationship with Midoriya.
The offspring of Todoroki and Momo could be great main characters. With Todoroki's ice - fire quirk and Momo's creation quirk, their child might have a really unique and powerful combination of abilities. The character could struggle with the high expectations that come from having such powerful parents.
They might be really confused at first. The world of 'Bnha' is so different from the historical and musical context of 'Hamilton'. But some characters could get inspired by the themes of ambition and fighting for what you believe in that are in Hamilton fanfiction.
All Might could be a great pairing. His powerful and heroic image combined with Nezu's intelligence could lead to some really interesting interactions. They could work together to solve a big threat to the hero world.
