You know we all have to thank Wally Wood, who first drew "
Power Girl" for DC, drawing her as relatively busty, with a figure and build conforming in appearance to other comic book women at that time. Later Wood was was convinced the editors were not paying any attention to anything he did, so the story goes as told be Wood's inker, that each issue Wood would then draw PG with a slightly larger bust, until after seven or eight issues someone finally said, "Hey, what's with the tits?" Which was when it stopped.
Later artist's reduced her bust, portraying PG as having a highly athletic but slender physique. Then for "
Justice League Europe" artist Bart Sears restored her bust. In his limited series "
Kingdom Come", Alex Ross later drew her as the older "
Power Woman" with a larger bust and a heavily, muscled physic, as if she was a female bodybuilder.
Consistently, artists depict Kara is as a large breasted young woman, most recognized for her shapely curves, who does not have a problem wearing a costume that shows it off. Once when another woman asked about her costume, she replied, "It shows what I am, female and healthy. If men want to degrade themselves by staring, that's their problem, I'm not going to apologize for it."
In another instance, Kara told Superman, who asked about her cleavage window, "The first time I made this costume, I wanted to have a symbol, like you do. I just couldn't think of anything, so I left the hole. I thought eventually, I'd figure it out. So far I still haven't come up with an idea to replace it."
So thanks to Wally Wood, and a few other artists, boob-loving guys have the
Power Girl we've all come to love and enjoy, in both the comics, and at conventions when cos-players dress up as her.
