The theme of growth is also very common. Both characters experience growth in different ways. Bakugou grows in terms of his emotional intelligence and how he treats others, especially Deku. Deku grows in his ability to stand up for himself and not let Bakugou's words and actions break him. And there's often a theme of communication too. How their lack of proper communication has led to the situation and how better communication can solve their issues.
Deku might be initially shocked. He's used to Bakugou's aggression, but an actual injury is different. He could be in pain and disbelief at first. Then, he might try to downplay it, especially if he doesn't want to cause trouble for Bakugou, because Deku is generally a very forgiving character.
The accident could also have an impact on the overall dynamic of their friend group. Their friends might take sides, some feeling more sympathetic towards Deku and being angry at Bakugou, while others might understand it was an accident and try to mediate. This could create tension and interesting plot developments in the fanfiction.
One popular 'bakugou hurts deku fanfiction' is 'The Pain Between Us'. It delves deep into the complex relationship between Bakugou and Deku, exploring how Bakugou's actions can sometimes cause emotional harm to Deku. Another is 'Scars of Words' which shows how words from Bakugou can cut deep into Deku's self - esteem.
One possible motive could be a long - held grudge that has festered over time. Maybe Bakugou's constant bullying in their past finally pushed Deku over the edge. Another could be some sort of mind - control or dark influence that made Deku act out of character.
Some characters might try to understand Deku's motives. Kirishima, who was close to Bakugou, would be angry at first but might also try to find out if there were any extenuating circumstances. However, many would be afraid of Deku, seeing him as a threat now that he has killed one of their own.
The relationship could start with hatred. Bakugou may initially be enraged that Deku has become a villain. But as time passes, he starts to see the reasons behind Deku's transformation, which could lead to a more complex relationship.
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.
It's popular because it explores a complex and often tense relationship. The contrast between Bakugou's aggressive nature and Midoriya's more timid one creates a lot of drama. People are drawn to seeing how these two characters interact in a more negative light, as it adds depth to their relationship.
Well, I'm not sure about a specific 'deku x bakugou dies fanfiction' that is the best. However, many fanfiction writers might explore this concept in different ways. Some might focus on the emotional aftermath for the other characters, while others could create alternate universes where this event leads to a whole new set of adventures or challenges for the remaining characters in the My Hero Academia universe.
