Samus is more often than not portrayed as a pin up girl. She's a generic blonde with a nice ass, and nerds have been fawning over that for a while. I've always thought that her sex was irrelevant, but nowadays it seems to be the major selling point on the character.
That bugs me. Now, I'm the first to sexualize something. The toph images are perfect evidence of that. However, Samus has become too far sexualized. I think its important to remind ourselves why she's so beloved, and no it's not for her spectacular ass.
