sexy robot women count, why not men?), Bane and the Evil Martian are showing about the same amount of skin. But let's face it, there are some basic differences in the way these costumes are presented. The togs of Star Sapphire and the Cheetah are designed to be sexy and titillating as a typical male fantasy fulfillment. The clothing of the men are not to excite but meant to display power and prowess albeit of the "Jersey Shore ab-display" variety.
On the plus side Star Sapphire is depicted as having more fabric in her outfit than the comic book version but that probably has more to do with the standards and practices of a video meant for a somewhat younger audience.
