Growth is another theme. Through the experience of the personality switch, both characters often grow in different ways. Bakugou might learn humility when he has Deku's personality, and Deku could learn to be more assertive. This growth can lead to a stronger bond between them in the end. In many of these fanfictions, the two characters end up understanding each other better after going through the switch, which is a form of growth for both of them.
One popular 'Deku and Bakugou personality switch fanfiction' is 'Switched'. In it, the change in their personalities leads to really interesting character interactions. Deku with Bakugou's brashness and Bakugou with Deku's more reserved and analytical side create a whole new dynamic in the story.
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.
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.
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.
Well, it could be because some fans see a complex and often tense relationship between Deku and Bakugou in the original story. In the series, Bakugou has bullied Deku in the past. So, some fans might explore this darker side of their relationship in fanfiction, imagining that Deku could hold deep - seated hatred for Bakugou due to all the past abuse.
One common theme is revenge. Since Bakugou has bullied Deku, in these fanfictions, Deku might seek revenge on Bakugou for all the pain he has caused. Another theme could be self - discovery. Deku may realize his own strength and worth through his hatred for Bakugou and break free from the shadow of being bullied.
