In Junko x OC fanfiction, Junko often retains her complex and unpredictable nature from the original Dangan Ronpa. Her character might be explored in new relationships with the original character (OC). For example, the fanfiction could focus on how Junko's chaotic personality affects the OC, whether it's through manipulation or an unexpected bond forming.
Another theme could be the power of love or connection in a very dark and dangerous world like the one in Danganronpa. Their relationship in fanfics might be shown as something that can change the course of events, or at least change them as individuals. For example, Makoto could bring out a different side of Junko that was previously hidden, and vice versa. This can make for some really engaging and complex storylines.
Some 'junko x komaeda fanfic' may have themes of redemption or change. Maybe Komaeda tries to change Junko's more malevolent ways, or vice versa. It's an interesting way to play with the characters' established natures in the original work.
A frequently seen theme is the exploration of their opposite personalities. Makoto is hopeful and kind, while Junko is often associated with despair. Fanfics often play with how these two extreme personalities interact and whether they can find common ground. Also, the theme of change is common. Junko might change due to Makoto's influence, or vice versa in some cases.
One way is through shared interests. Maybe the OC has an interest in chaos or despair like Junko does, which could be the basis for their relationship. Another way could be that the OC is a contrast to Junko, and through their interactions, Junko starts to see things in a different light. For example, if the OC is very positive and hopeful, it could be a source of conflict or growth for Junko's character.
First, develop your OC well. Give them a unique personality, backstory, and motivation. For example, if your OC is a detective trying to solve Junko's crimes, that could create an interesting dynamic. Then, understand Junko's character. She's complex and manipulative. Try to capture that in your interactions. Keep the plot engaging, like having a mystery or a power struggle between the two.
