Several characters have met their demise in the MHA manga, but it's a bit complex to list them all precisely. Some of the notable ones include [mention specific characters if known].
I think it's hard to say for sure. There are a few characters who could potentially be the traitor, and it's all part of the mystery and suspense of the story.
Deku is quite popular. His journey to become a great hero can be easily translated into a gaming context, like him leveling up his skills. Bakugo is also a favorite. His brash personality and powerful quirk make for exciting scenarios in fanfictions.
Izuku Midoriya is really popular. His journey from being a quirkless boy to a powerful hero - in - training is very inspiring. Katsuki Bakugo is also popular. His explosive personality and strong power make him stand out. And Ochaco Uraraka with her cute appearance and kind heart is liked by many.
I don't know for sure as it depends on the specific fanfic. It could be a main character from the original My Hero Academia series who is put in a new and difficult situation that makes them 'broken but not defeated'.
Some minor characters have died, but the major character deaths are relatively few. The fate of characters can change depending on the story's progression.
Well, it's a really tough call. But some might say Goku from Dragon Ball is the strongest. He has the ability to reach extremely high power levels through intense training and various transformations. His Saiyan blood gives him an edge, and he has fought against some of the most powerful foes in his universe and come out on top. Plus, his Kamehameha wave is a very iconic and powerful attack.
I'm not sure as I haven't read it, but it could be the black fox character if there is one. Maybe some original characters created by the fanfic writer who interact with the MHA canon characters.
To some extent, it is popular. There are many online platforms where MHA adult fanfiction can be found. The popularity might stem from the fact that the MHA world has a rich cast of characters and a complex universe. Fans who enjoy adult - oriented storytelling might use these characters to create their own narratives that are more in line with their interests in terms of relationships, power dynamics, and personal growth, all with an adult twist.
