I'm not one of those guys that stopped playing Metroid when they found out Samus was a chick. I just said "Wow, a girl that kicks ass!" And kept on playing.
Well, Samus is a kick ass women, who isn't running around in bikini-ware, bouncing F cup briasts, and a katana (or what people are lead to believe as a Japense doom blade of ultimate destruction and awesome). She's in a full metallic suit (well, most of the time) with a giant phallic blaster on her right arm
.
Basically, she's what kick ass action heroines should be like, not some scantily-clad woman with D cups who likes to jump around a lot, act extremely flirty or yells why everyone is staring at her chest/butt while wearing said strings thus giving very little to the imagination. But instead she's has a very dominating presence, and wears armor that could take a broadside shot to the gut.
