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.

One popular storyline is when Flash and Supergirl team up to fight a common enemy from another dimension. This allows for a lot of action and showcases their different powers working together.
In the fanfiction, their teamwork could be shown as a bit chaotic at first. Each hero has their own way of doing things. Arrow is more stealthy and methodical, Flash is impulsive and fast - acting, and Supergirl is more of a straightforward hero. But when they face a really tough enemy, they realize they need to combine their approaches. So Arrow might come up with a plan that incorporates Flash's speed for a quick execution and Supergirl's strength to overpower the enemy's defenses. They would have to communicate constantly and adjust their teamwork as the situation changes.
A plot twist could be that a character from one of the shows, who seems to be a minor or unassuming figure, is actually a powerful being from the future sent to manipulate the events of the crossover. This person has been subtly guiding the actions of the heroes, and when the truth is revealed, it completely changes the heroes' perception of the events they've been through and who they can trust.
One idea could be that Flash and Supergirl team up to stop a powerful alien villain who is causing chaos across both their cities. The villain could have the ability to manipulate time and space, which would make it a real challenge for the two heroes.
Definitely, Cisco Ramon from Flash. He can add some tech - savvy humor and his ability to create new gadgets can be really useful in the crossover. For example, he could make a device that helps Supergirl deal with a new type of kryptonite - like threat.
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.
One inspiring Supergirl story is her fight against powerful villains to protect Metropolis. She uses her super strength, flight, and heat vision to keep the city safe. For example, when a group of alien invaders threatened the city, Supergirl was the first to stand up and fight them off, showing great courage.
