Superman's younger, blonder cousin is growing restless that she's not utilizing her otherworldly capabilities for something bigger than being the menial assistant to media mogul/Miranda Priestly clone Cat Grant (Calista Flockhart).

"It's not that I don't see your frown," explains Cat. "It's just that I don't care enough to ask why it's there."

But with a little inspiration from her big cuz

and a crashing plane...

Kara realizes she can be the hero the world needs.

So she teams up with the government to fight aliens and other baddies.

And does stuff like this.

And this.

Oh, and this.

And a special behind-the-scenes look at how it all came together.
