One popular concept is the backstories of the villains. Many fanfics explore what led them to become villains in the first place. For example, they might delve into Tomura Shigaraki's past and how he was influenced by All For One. Another concept is villain redemption arcs. Writers like to imagine if villains could be redeemed and how they would go about it in the context of the BNHA world. And then there's the idea of villain alliances and power struggles within their ranks, which can make for very interesting and complex plotlines.
One popular 'bnha villain izuku fanfic' might be those that explore his transformation into a villain due to being constantly bullied and overlooked. For example, some stories could show how his experiences with Bakugo's constant aggression pushed him to the dark side. Another aspect could be his different powers and how he uses them for villainous purposes, like his One For All ability being used in unexpected and menacing ways.
One idea could be to create a villain OC who has the power to manipulate time in small increments. This could lead to really interesting scenarios in battles against the heroes. For example, they could slow down time just enough to dodge attacks and then speed it up suddenly to surprise their opponents.
In the 'bnha reacts to villain deku fanfiction', different characters would have diverse reactions. Uraraka would likely be heartbroken. She has always seen Deku as a source of inspiration and a good friend. So, seeing him as a villain would shatter that image for her. The teachers, like Aizawa, would be concerned about how the situation came to be. They would probably start to question their own teaching methods and the environment that led Deku to become a villain.
Dabi would also work well. His vendetta against Endeavor could be a starting point for his reform. As he discovers more about his family and the truth behind his father's actions, he might decide to change his ways and use his power for good instead of revenge.
The plot could involve the female villain saving Deku from a dangerous situation. She might be in the right place at the right time and use her villainous powers for good in that instance. This would then start a chain of events where Deku is curious about her motives, and she has to keep her true nature hidden while getting closer to him.
One possibility could be a story where the female villain is initially drawn to Deku's underdog status. She might secretly admire his determination to become a hero despite being quirkless at first. In this fanfiction, she could start observing Deku from afar, analyzing his every move and decision during battles or in school. This could lead to an interesting dynamic where she is conflicted between her villainous nature and her new - found admiration for Deku.
In some 'bnha villain deku fanfic', Deku could be turned into a villain by a powerful villain who manipulates his sense of justice. For example, the villain convinces Deku that the current hero system is corrupt and only by destroying it can true justice be achieved. This could lead to some really intense battles between Deku and his former friends.
I really like 'Villainous Intent: An OC's Tale'. This fanfic does a great job of integrating the OC villain into the existing BNHA world. It shows how the OC interacts with the well - known heroes and villains from the original story, and the plot twists are really exciting.
Often, bnha female villain oc in fanfic are highly intelligent. They need to be smart to outwit the heroes. They can plan elaborate schemes and manipulate situations to their advantage. Also, they tend to have a certain charm or allure. This helps them in getting what they want, whether it's influencing other characters or distracting their enemies. In addition, many of them are quite independent, not relying on others to achieve their goals.
