The plot could involve a mind - control situation. Some villain tries to control Supergirl, but Flash manages to break the control. In the process, they have a deep emotional connection and kiss. This would show Flash's heroism and how it affects their relationship.
A good Flash and Hawkgirl kiss fanfiction often has well - developed characters. The writer should understand the personalities of Flash and Hawkgirl from the original comics or shows. For example, Flash's quick - wittedness and Hawkgirl's strong - willed nature should be evident in the story.
Often, it's the vivid imagery and the depth of character development achieved in just a few words. The ability to convey a powerful story in such a limited word count is what makes it compelling.
Immediately after the kiss, they might be in shock. But then they could start to act more protective of each other. Their relationship would likely become more intimate, sharing deeper secrets and relying on each other more during missions.
The plot could revolve around an alternate universe. In this universe, they are not superheroes in the same way. Artemis is more of an artist and Kid Flash is just a regular guy with a love for speed. They meet in a more normal setting, like a coffee shop. As they get to know each other over time, their relationship develops and the kiss is a natural progression of their growing feelings.
Love at first sight could be a reason. Maybe they meet for the first time during a team - up and there's an instant spark between them that leads to a kiss.
Another possibility is that it could involve a new character created specifically for this fanfiction. This character could be a hybrid of Twilight - like abilities and some form of super - speed, and they could be the one sharing the kiss with either a well - known Twilight character or a Flash character.
One idea could be a crossover of the Twilight universe and the Flash's world where their powers interact in unique ways during the kiss. Maybe the vampire's immortality and the Flash's speed combine to create a sort of time - frozen moment during the kiss.
There are some really interesting Flash and Supergirl kiss fanfictions out there. One that I liked had them in an alternate universe where they were the only ones with powers and they had to rely on each other more. Their relationship developed gradually and the kiss was a really sweet moment in the story.
Another option is to check out specific DC Comics fan communities. There are forums and groups dedicated to discussing DC characters and their relationships. Members might share or recommend some great fanfiction involving Flash and Hawkgirl's kiss. For example, Reddit has some active DC - related subreddits where you can ask for such stories.
