One common theme is self - discovery. The reincarnated OC often has to figure out who they are in this new world and how their previous life and new circumstances interact. Another is the struggle for power. Since the MHA world is centered around quirks, the OC usually has to find a way to gain power or use their unique skills.
One common theme is identity struggle. Since the OC is now in Shoto's body, they have to figure out how to balance their original self with the new identity. Another theme is power exploration. They have to learn to use Shoto's quirk effectively. And also, family relationships are often explored as Shoto has a complex family situation in MHA.
Sure. 'Reincarnated as a Quirkless Hero in My Hero Academia' is a great one. It has an interesting plot where the OC, who is reincarnated, has to find their way in the MHA world without a quirk at first. Another one is 'My Reincarnated Life in MHA'. It focuses on the character development of the reincarnated OC as they interact with the well - known MHA characters.
Well, there's 'My Reincarnation as Shoto' which has an interesting take on the concept. The story focuses on how the OC's memories and personality change the way Shoto approaches relationships with his family and friends in the MHA universe. There are also some fanfics that are less well - known but still great, like 'Reincarnated into Shoto's World' where the OC - turned - Shoto has to deal with the villains in a unique way based on their previous life experiences.
One fanfic I remember has the OC reincarnated as Izuku with the power to manipulate time on a small scale. It's really cool because he uses this power to analyze battles and opponents' moves more effectively. He can slow down time for a few seconds during combat to gain an advantage, which is a very unique take on Izuku's character development.
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.
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.
