One common theme could be the exploration of their superpowers in unique ways. For example, they might team up to face a powerful villain that neither could defeat alone. Another theme could be the development of a romantic relationship between Flash and Supergirl, which might involve them overcoming differences in their personalities and powers. Also, there could be themes related to self - discovery as they interact with each other and grow as characters.
Well, Cisco Ramon from The Flash would be a great addition. He could use his tech skills to create some new gadgets or figure out ways to counter the villains' powers. Also, Martian Manhunter from Supergirl's side. His shape - shifting and telepathic abilities would add a whole new dimension to the story.
Writers can create tension by introducing a powerful enemy. For instance, a villain who can manipulate time, which would put Flash's speed and Supergirl's powers to the test. Another way is through relationship drama. If there are misunderstandings between Flash and Supergirl, like Flash thinking Supergirl doesn't trust his abilities, it can create tension.
First, you need to understand the characters well. Flash is known for his speed and his light - hearted personality, while Supergirl is strong, brave and has a sense of justice. Then, come up with an interesting plot. It could be a new villain they face together or a situation that challenges their abilities.

If Barry kidnapped Supergirl in fanfiction, it could be a really interesting plot twist.
