Well, one characteristic is the morally ambiguous protagonist. In negative hero novels, the main character often has both good and bad qualities. For example, they might be driven by noble goals but use immoral methods to achieve them.
It can damage the reputation of the original 'hero academia' series. People may associate the inappropriate content with the clean and positive image of the original work.
It promotes a wrong view of relationships. Rape is a serious crime in real life, and depicting it casually in a novel can mislead readers into thinking it can be a part of a 'romantic' relationship, which is extremely harmful.
One example could be 'The Picture of Dorian Gray' by Oscar Wilde. Dorian Gray is a sort of negative hero as he indulges in hedonism and moral decay while maintaining a beautiful exterior. His actions are often self - serving and go against traditional moral values.
It can be offensive. Such fanfiction goes against the positive and clean - cut image of the 'My Hero Academia' series. It may also make fans who are expecting heroic and inspiring stories feel disgusted.
One common theme is power struggle. The negative hero and the demon lord often have to fight for power, either against each other or against other forces in the story. For example, in 'Overlord', Ainz has to constantly assert his power in the new world.
There are multiple negative impacts. It shatters the idea of a healthy and consensual relationship that should be at the core of a romance novel. It can also cause psychological harm to readers, especially vulnerable ones. Moreover, it goes against the values of equality and respect that should be promoted in literature. By including such a plot, it can also lead to a negative perception of the genre as a whole, making people think that romance novels can tolerate or even promote such unacceptable behavior.
One such novel could be 'Overlord'. In it, the main character is kind of a 'demon lord' figure in the new world he finds himself in. He has his own goals and methods that are not always heroic in the traditional sense.
It can desensitize readers to serious issues like non - consensual drugging. Such a plot may make light of a very serious and illegal act in real life.
One negative impact is that it can corrupt the original positive image of My Hero Academia. The series is known for its inspiring storylines about heroism, and this kind of fanfiction with inappropriate content can taint that. Another is that it may expose younger fans to adult - like content that they are not ready for.
