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.
For finding good villain deku x bakugou fanfic, AO3 is a top choice. It not only has a vast number of stories but also a very active community. The site allows for detailed tagging, which means you can narrow down your search precisely to what you want. For example, if you prefer a certain genre like angst or action, you can filter accordingly. Fanfiction.net has been around for a long time and has a lot of content, but as I said, the quality can be a bit hit - or - miss. Additionally, Reddit has some My Hero Academia sub -reddits where fans discuss and recommend fanfics. You could post a request there asking for good villain deku x bakugou fanfics and chances are you'll get some great recommendations from the community.
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 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.
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.
I really like 'A New Beginning' in the bakugou bullying deku fanfic genre. It starts with a very intense bullying scenario but then takes an unexpected turn as Deku finds an inner strength that not only helps him deal with Bakugou but also makes him a more confident character overall. It's quite engaging.
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.
Overall, their relationship in the manga is full of tension and competitiveness. Bakugou often sees Villain Deku as a threat, leading to many intense encounters.
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.
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.
I really like 'Deku and Bakugou: A New Chapter'. It takes place after the main events in the series and explores how they face new challenges together. It's a bit of a slow - burn in terms of their relationship development, but that makes it all the more satisfying when they finally start to understand each other on a deeper level.
One great Bakugou x Deku fanfic is 'Unlikely Allies'. It explores their relationship in a post - war scenario where they have to work together to rebuild society. The character development is really well - done.
