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.
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 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.
Deku might be completely shocked at first. Since Bakugou has always been so aggressive towards him, he would never expect such a confession. He might just stand there, mouth agape, not knowing what to say.
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.
One concept could be that Villain Deku manages to manipulate Bakugou into joining his side. Maybe he plays on Bakugou's insecurities or his desire for power. Another could be a world where they are both villains from the start and they form a power - hungry duo, causing chaos everywhere. A third concept might be that Villain Deku kidnaps Bakugou as part of a grand scheme to get back at the hero society that they both feel has wronged them in some way.
To develop their relationship realistically, start with their existing dynamic. Bakugou is often aggressive towards Deku, so a slow change is needed. Maybe have them be forced to team up. As they face challenges together, Bakugou could start to respect Deku's abilities bit by bit. For example, if they are in a battle against a powerful villain and Deku comes up with a clever strategy, Bakugou might grudgingly admit Deku's smarts.
Well, AO3 is definitely a great place to start. It has a tagging system that makes it easy to find the specific type of fanfic you're looking for. When you search for 'villain deku x bakugou', you can also filter the results by things like rating, word count, and completion status. Fanfiction.net also has a decent selection. However, you need to be a bit more careful there as the quality control isn't as strict as on AO3. You could also look into Tumblr. There are a lot of My Hero Academia fans on Tumblr who might post about or recommend good villain deku x bakugou fanfics. Some of them might even have their own fanfic blogs where they share their work.
A possible plot is a power struggle between them. Since Deku has turned villain, he might see Bakugou as a threat to his plans. Bakugou, on the other hand, wants to bring Deku back to the light. This creates a constant back - and - forth of battles, both physical and psychological, as they try to outwit each other.
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.
