A DC Comics character. Origionally the cousin of Earth-2's Superman, she is quite possibly one of characters who got most screwed-over after crisis. To keep Earth-1's Superman the ONLY survivor of Krypton, they gave her various random pasts, including one where she was from Atlantis which somehow led to her having a miraculous virgin birth.
Thankfully, with Infinite Crisis, she has recieved her old history back with the expectation of at least a temproary return of the multi-verse. She also has very *ahem*ample*ahem* assets along with a strategically placed hole that, if any bigger, would reveal more than allowed.
*From "JSA CLASSIFIED #2"*:
Power Girl (talking with Superman): People always ask me why I have this hole right here. They think I'm showing off...or just being lewd. But the first time I made this costume, I wanted a symbol like you.
I just...I couldn't think of anything. I thought, eventually, I'd figure it out. And close the hole.
But I haven't.
Power Girl (real name Kara Zor-L, also known as Karen Starr) is a DC Comics superhero. Power Girl is the Earth-Two counterpart of Supergirl and the first cousin of the Earth-Two Superman. She's a staunch feminist, aggressive fighter and overall babe with a fitness model physique and sublime cleavage. She's currently the chairman of the Justice Society of America.
When questioned about her revealing costume, Power Girl responds: "(it) shows what I am: female, healthy, and strong. If men want to degrade themselves by staring and drooling and tripping over themselves, that's their problem, I'm not going to apologize for it."
