There could also be other characters involved. For instance, some of the Flash's friends or allies from his usual superhero team might make an appearance. They could either be helping the Flash deal with Jinx or getting caught in the crossfire of their encounters. Additionally, Jinx might have her own group of followers or partners in crime that could add more depth to the story.
One interesting plotline could be Jinx causing chaos in the Flash's city, and the Flash having to figure out how to stop her without using too much force. Maybe Jinx has stolen some important tech that could disrupt the city's power grid.
Another theme is the transformation of their relationship. Usually, they start as enemies or at least as rivals. The fanfiction then shows how they gradually develop feelings for each other, and the kiss is a significant milestone in that transformation. For instance, in many stories, their interactions during battles or chases start to have a different undertone, leading to the kiss.
One common theme is the idea of forbidden love. Since they are often on opposite sides, their relationship is seen as something that shouldn't happen. Another is the concept of redemption, where Jinx might be redeemed through her relationship with Kid Flash. And of course, the theme of unexpected attraction is also prevalent.
Well, I've come across a couple. Some of them are really interesting as they explore the relationship between Jinx, who is often portrayed as a complex character, and Kid Flash. They might start with a chance encounter that leads to the kiss and then develop the story from there, like how their relationship affects their respective teams and friends.
Another possibility is that a character from Glee, say Rachel Berry, discovers she has some sort of meta - human ability similar to the Flash. The Flash has to come and train her to control it while also dealing with the chaos that her new powers cause within the glee club dynamic.
Their relationship could start with a simple truce. After a fight, they both realize that they are evenly matched and instead of constantly battling, they decide to call a temporary halt. This could lead to them having conversations and slowly understanding each other.
Jinx's powers would likely shake up the team dynamics. Her hex powers are unpredictable, which could make some members of Young Justice a bit wary. For instance, if she accidentally hexes a teammate during a mission, it could cause tension.
Another plot might involve Jinx having a past connection with one of the Young Justice members. Maybe she knew one of them before she became a villain. This connection could lead to a lot of internal conflict within the team as they debate whether to trust her or not. It could also create an interesting character arc for Jinx as she tries to redeem herself in the eyes of the team.
One popular plot theme could be the idea of redemption. Jinx, being a villain initially, might be on a path towards changing her ways with the help of Kid Flash. For example, they could be forced to work together on a mission and Jinx starts to see the good in heroism through Kid Flash's actions.
