A possible plot is that there's a new threat in the city that affects both heroes and villains. Bakugou and Toga find themselves in the middle of it. Toga's ability to transform and Bakugou's powerful quirk could be combined in an unexpected way to fight this new enemy. As they work together, they begin to develop feelings for each other. Toga might be attracted to Bakugou's strength and determination, while Bakugou might start to see Toga as more than just a villain, as someone who has her own reasons for doing what she does.
One idea could be that in an alternate universe, Bakugou and Toga are forced to team up during a villain - hero cooperation event. They start off hating each other but gradually come to understand each other's motives. Another could be a situation where Toga takes on Bakugou's appearance to get closer to the other heroes and ends up having some really strange interactions with Bakugou himself. Maybe she tries to use his appearance to cause chaos but then realizes she doesn't really want to hurt him in the process.
Well, here's a plot. Toga has a vision in which Uraraka is in danger from a new villain. She decides to protect Uraraka, even though they are on opposite sides. Uraraka is initially suspicious but then realizes that Toga is being genuine. This could lead to a strange friendship where they have to keep their relationship a secret from both the heroes and the villains. They could then start to influence each other in small ways, like Uraraka teaching Toga about the value of friendship and Toga showing Uraraka that things aren't always black and white.
One common plot point is the conflict between their respective sides. Bakugou is a hero - in - training and Toga is a villain. So there's often a struggle between their loyalties. Another is Toga's obsession with Bakugou, which can lead to her trying to get closer to him in various ways, like infiltrating his group or following him secretly.
One idea could be that Toga, in an attempt to understand Izuku better, tries to live a normal life like him for a while. She disguises herself and enrolls in U.A. High, leading to a series of comical and tense situations as she tries to hide her true identity from Izuku and the other students.
Well, in fanfics about 'My Hero Academia Bakugou x Toga', it could show a dynamic where Bakugou initially rejects Toga's advances due to her villainous nature. But as the story progresses, they might find some common ground, like their strong wills. It's a chance for the writer to play with the idea of two very different characters from opposing sides interacting in unexpected ways.
One idea could be that the genderbent Bakugou has to deal with different expectations in hero society. Since she's female now, some might underestimate her strength at first. Another plot could involve her having a different dynamic with the other characters, like a more sisterly bond with Midoriya.
How about a fanfiction where Himiko Toga is stranded on an island? She has to survive without her usual means of getting blood. This could lead to her developing new skills and maybe even forming an unexpected friendship with a local creature or another stranded person. It would be a unique take on her character, showing her adaptability.
One idea could be that Deku, turned villain, challenges Bakugou's view of heroism. He could expose the flaws in the hero society that Bakugou blindly believes in. For example, Deku might target the way heroes are ranked and how it creates a cut - throat environment. This would force Bakugou to re - evaluate his own pursuit of being the top hero.
A plot could revolve around Toga disguising as someone close to Deku, like Uraraka. At first, Deku is suspicious but as they interact more, he realizes it's Toga. Instead of fighting her right away, he tries to understand why she is so obsessed with him. This could lead to a series of events where they both learn more about each other's pasts and what led them to be who they are.
One interesting plot could be that they are forced to team up for a really difficult mission. During this mission, they start to understand each other's strengths and weaknesses better. Izuku might learn some new combat techniques from Bakugou, and Bakugou could gain a new respect for Izuku's strategic thinking.
A plot could involve a villain who targets both of them specifically. This forces them to rely on each other for survival. Bakugou's powerful quirk and Uraraka's zero - gravity ability would be used in creative ways to fend off the villain. Along the way, they might discover some hidden secrets about each other that strengthen their bond.
