Bakugou could use his words. He might tell Deku that he believes in him. For example, he could say 'Deku, you may be a nerd but you're a strong nerd.' It's a backhanded compliment but it shows he has faith in Deku.
One common theme is rivalry. Their intense competition to be the best hero is often explored, like in many fanfics where they constantly try to outdo each other in training or in real battles. It shows their determination and drive.
One possible plot is that Bakugou has been secretly in love with Deku for a long time. He observes Deku's kindness and growth, and it makes his heart flutter. He decides to propose when they are alone one day. He might start by reminiscing about their journey together, from being rivals to becoming something more, and then pop the question.
The main characters are Bakugou and Deku. Bakugou is often portrayed as a brash and confident character, while Deku is kind - hearted and determined. In this fanfic, their relationship takes a romantic turn with Bakugou being the one to propose.
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.
One popular Bakugou and Deku fanfic is 'Deku vs Kacchan: Rematch'. It delves into their complex relationship, exploring how they grow both as rivals and friends. The story has some great action scenes that really show off their different Quirks in an exciting way.
One possible plot could be that Deku has had a really tough day at hero training. He's doubting his abilities and feeling down. Bakugou, who has grown as a person, notices. He might start off a bit rough, like his usual self, saying something like 'Don't be such a crybaby, Deku!'. But then he actually sits down with Deku and shares some of his own insecurities about being a hero. He tells Deku that everyone has bad days and that he's seen Deku's progress and knows he's strong. This comforts Deku and they end up having a more understanding relationship.
It could start with Deku taunting Bakugou. As a villain, Deku would have a new - found confidence and would use it to get under Bakugou's skin. He might leave cryptic messages for Bakugou, hinting at their past and how Bakugou used to bully him. This would make Bakugou angry but also curious about what Deku has become.
