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.
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.
One common theme is redemption. Bakugou, who was often a bully in the original story, has a chance to redeem himself in his relationship with female Deku. For example, in many fanfictions, he realizes his past mistakes and tries to make it up to her.
One aspect of Deku x Bakugou fanfiction is the exploration of their complex relationship. In the original series, they have a history of rivalry and conflict. Fanfiction often delves into how they might overcome these issues and develop a deeper bond. It could be through shared experiences in battles or personal growth moments. Writers might show Bakugou learning to respect Deku's growth and Deku seeing Bakugou in a new light.
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.
