"Justice League Unlimited" Initiation (TV Episode 2004) - Nicholle Tom as Supergirl, Kara Kent

Supergirl : So, aren't you going to give me the "You did good" speech?

Green Lantern : You're headstrong, unprofessional, and reckless. If you ever jeopardize yourself or your teammates again by running off half-cocked without a battle plan, I will personally see you're kicked out of the League. I don't care who your cousin is. And incidentally... you did good.
Supergirl : So, you're gonna let me drive, right?

Captain Atom : Whoa, wait a minute! Has she been qualified in a Javelin?

Supergirl : Why don't you take the stick out, Corporal?

Captain Atom : Captain.

[Kara sticks her tongue out at him]
Supergirl : [Green Arrow and Captain Atom are arguing] HEY! We've got a giant out of control robot out there! But if you two guys are too busy playing Alpha Males Smackdown, I guess I'll just have to deal with it myself.

[starts to leave]

Green Lantern : SHAYERA!

[everyone turns to GL]

Green Lantern : You need a plan. You need to find its weakness.
Captain Atom : [finding the Hazmat team] What are we up against?

Supergirl : He asked you a question!

Soldier : Don't answer them! That's classified info...

[Supergirl grabs him and holds him up with one arm]

Supergirl : I've just about had it with you guys! You've got to the count of five!1... 4...

[eyes start to glow]

Captain Atom : I'd speak up if I were you.

Nicholle Tom: Supergirl, Kara Kent
