That Physics-take-a-coffee-break "Check out my chest and my ass (and, in this case, package) AT THE SAME TIME" pose is a little hard on the spine.
This came out of a recent conversation I was having with some friends: " I often wonder how different the character would be treated if Samus Aran was a dude. I'm just sayin', you don't see "Zero Suit" Master Chief...."
Basically it ended with me being triple-dog-dared to draw Zero Suit Master Chief and since I hadn't drawn anything all week due to my recent bought with con-flu, I thought "You fools know not what you will UNLEASH!!! but I'll freaking DO IT!" XD
Anyway, if one armored video game character has to get down to their skivvies, it's only fair the rest of 'em do it. Down with double standards!

::And wow, looking over the comments. It's funny how people think nothing of seeing women sexualized in this manner, but if it's a dude..HOLY CRAP!!!!::
I am a gay dude [with a feminist outlook], so I can't really say I can empathize- but props to you as a straight guy (?) with the self-awareness and societal awareness to create this image and explain the double standard that is so rife- the pic is actually funny and well drawn too
