Definitely Deku. His journey from being a quirkless boy to a powerful hero gives a lot of room for creative interpretations in crack fanfictions. Writers can come up with all sorts of wacky scenarios for him, like getting a completely new and unexpected quirk.
Bakugo is also quite popular. His hot - headed personality can be used to create some really interesting and explosive (literally) situations in fanfictions. He might get into some absurd battles or have some really strange interactions with other characters due to his temper.
Deku is definitely one of the most popular. Fans like to explore how his character would develop if he were female, especially considering his relationship with other characters like All Might and his classmates. Bakugo is also a common choice. Imagining him as a girl could completely change his hot - headed and aggressive personality, or at least how others perceive it. Ochaco is another popular character for gender - swapping. Her sweet and kind personality as a male could bring new dynamics to her relationships with the other characters.
Izuku Midoriya is often popular in these fanfics. Since he's the main character in the original series, writers like to explore how he would handle god - like powers. They might give him the ability to control all quirks at once or something similar.
All Might is quite popular in boku no academia fanfiction. His status as the former number one hero and his relationship with Midoriya attract a lot of attention. Writers might explore his past more deeply or create scenarios where he still has a more active role in the story. Uraraka Ochaco is also well - liked. Her cute personality and her feelings for Midoriya are often explored in fanfictions. And then there's Shigaraki Tomura. His role as a villain and his mysterious backstory make him a fascinating character to write about in fanfiction.
Another idea could be alternate universes where the roles are reversed. The heroes are the ones causing trouble and the villains are trying to maintain order. It gives a whole new perspective on the characters and their relationships. In these fanfictions, the character development can be really fascinating as they adapt to these new roles.
Another popular pairing might be Usopp and Mineta. Usopp's creativity with his gadgets and Mineta's rather unique quirk could create some interesting and comical interactions. They could get into all sorts of wacky adventures together in the fanfiction world.
Well, Uraraka is quite often written about. Her sweet personality and her crush on Midoriya are elements that many fanfiction writers like to play with. Shigaraki is also a common character in fanfiction. His role as the main villain in the series makes him a focal point for exploring the darker side of the boku no hero academia universe. And All Might, being the symbol of peace in the original story, is also frequently written into fanfictions, whether it's about his past or his influence on the new generation of heroes.
Well, obviously Mandalay herself is a main character. Then there could be her fellow heroes like Tiger. Students she mentors might also be main characters, like Kota who she has a connection to in the original story.
Izuku Midoriya is one of the main characters. He is the protagonist with the quirk 'One For All'. Bakugo Katsuki is also important, being Izuku's childhood friend and rival. Ochaco Uraraka, a female character with the quirk 'Zero Gravity', is among the main characters as well.
It's possible. If we consider the idea that the Boku no Hero Academia universe has a concept of our world's fanfiction, then some of the more tech - savvy or curious characters could potentially stumble upon it. Maybe a character like Izuku Midoriya, who is always eager to learn about heroes, might be interested in seeing how fans view the hero world in fanfiction. However, this is all in the realm of creative speculation as the original series doesn't touch on this directly.
Obviously, Izuku Midoriya is the central character. Then there are often characters like Ochaco Uraraka, who could be part of the harem as she has shown an interest in Izuku in the original series. Tsuyu Asui might also be included as she is a close friend and could potentially develop deeper feelings for Izuku in fanfiction.
