One popular theme is crossovers. Writers like to imagine what would happen if characters from different shows met. For example, a story where a Glee character gets superpowers like in Flash or Supergirl. Another theme is relationships. This could be romantic relationships between characters, either within the same show or across shows.
Fanfiction.net is also a great place. There are many talented writers who contribute to this platform. However, the quality can vary. So, it's best to read the reviews or summaries before diving into a story. Also, some fanfics might be part of a series, so keep an eye out for those.
If Barry kidnapped Supergirl in fanfiction, it could be a really interesting plot twist. Maybe Barry has been affected by some sort of red kryptonite - like substance that makes him act out of character. This would lead to a conflict between the Flash and Supergirl's friends and allies. They would be confused as to why Barry would do such a thing.
One of the best places to find Flash and Supergirl fanfiction is Archive of Our Own (AO3). It has a large collection of fan - created stories that cover all kinds of scenarios and relationships between the two characters. The site is well - organized, making it easy to search for specific tags or themes related to Flash and Supergirl.
One great Flash and Supergirl fanfiction is 'The Team -Up of Legends'. It shows an alternate universe where they have to work together against a powerful new villain. The story does a great job of portraying their different powers and how they complement each other in battle.
One idea could be that a powerful villain threatens both their cities simultaneously. Supergirl and The Flash have to team up, and in the fanfiction, their different powers and personalities could lead to some interesting interactions. For example, Supergirl's strength and The Flash's speed could be combined in unique ways to defeat the villain.
She might be interested because it offers a different perspective on human creativity. Glee is all about music, performance, and the power of the underdog, and fanfiction adds another layer of creativity to it. Supergirl, being an alien trying to understand humans, could find it fascinating to see how people imagine crossovers between her world and the world of Glee.
It's possible. Supergirl characters, like any fictional characters in a shared universe, could potentially be fans within their world. However, since there's no official crossover indicating this, it's all speculation. Maybe Kara (Supergirl) would be interested in Glee fanfiction as she seems to be interested in Earth's pop culture.
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.
There's no official indication that Glee watches Flash fanfiction. Glee is mainly centered around the high - school glee club and their musical adventures. Flash, on the other hand, is a superhero - themed show. Their worlds are quite different, so it would be a very niche and unexpected thing for Glee to be into Flash fanfiction.
