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.
No, it's not appropriate. Deku is a character with his own depth, goals, and story within the MHA universe. Fanfic should aim to explore his hero journey, his relationships in terms of mutual respect and support, not create content that focuses on inappropriate or disrespectful ideas like this.
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.
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.
I don't really have a list of specific 'mha deku x boobs fanfic' as it might lead to some inappropriate or objectifying content. Instead, if you like Deku, you could search for fanfics that focus on his growth as a hero, his friendships, and his challenges. For example, there are many fics that explore his relationship with All Might or his classmates in a positive and meaningful way.
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.
Growth is also a prevalent theme. Both characters are on a journey of self - discovery and improvement, and fanfics usually show how they grow both as individuals and in relation to each other. For example, Bakugou learning to control his temper and Deku becoming more confident.
One common theme is rivalry. Their intense competition to be the best hero is often explored, like in many fanfics where they constantly try to outdo each other in training or in real battles. It shows their determination and drive.
The popularity also lies in the potential for character growth within these fanfictions. Deku and Bakugou both have a lot of room for development, especially in their relationship with each other. Fanfiction allows for the exploration of their feelings, like Bakugou coming to terms with his jealousy of Deku's progress and Deku learning to stand up to Bakugou in a different way. These deep dives into their characters' psyches make the fanfiction appealing to many.
