One great 'izuku and fem bakugou fanfiction' is 'A New Bond'. In this story, they are forced to work together on a project at school. Fem Bakugou slowly starts to see Izuku in a new light as they overcome challenges together. It's a really sweet story that shows character growth for both of them.
One common theme is the power dynamic. Fat Gum has a lot of strength and experience, while Fem Kirishima might be portrayed as more of a newbie or someone looking to learn from him. Their relationship can develop around training and growing stronger together.
Villain Deku would likely be very manipulative towards Fem Bakugou. He might try to use her anger and pride against her. For example, he could taunt her about how the hero system has failed her in some ways, making her question her loyalty. Bakugou, on the other hand, would probably respond with aggression at first. She would not take kindly to Deku's villainous ways and would try to attack him. But as she realizes Deku has some valid points about the hero system, she might start to listen more and their interactions could become more of a debate rather than just physical combat.
The plot might involve a love - hate relationship. Villain Deku has his own motives and plans, and Fem Bakugou is in his way. But at the same time, there could be a past connection between them that resurfaces. For example, they could have been childhood friends before Deku's turn to villainy. This connection could make their encounters more complex and emotional. Bakugou could be torn between her duty as a hero - in - training and her feelings for Deku. And Deku, despite being a villain, might still have some soft spot for Bakugou which could lead to some internal conflict within him as he tries to carry out his villainous plans.

A '5 times bakugou fanfiction' could be really interesting. It might explore five different emotional states of Bakugou. One time could be when he was extremely angry and how that affected his actions. Another time could be when he was vulnerable, perhaps after a difficult battle. Then there could be a time when he was happy and celebrating a victory. And two more times could be related to his growth as a character, like the first time he realized he needed to change his attitude towards his friends, and the second time when he actually made a significant change in his behavior.
Bakugou might react with his usual anger. He could lash out at the bullies verbally or even physically, which might make the situation worse. For example, if someone makes a snide comment, he could respond with a loud and aggressive retort.
