Snake showing off his buns while kicking Zero Suit Samus. Samus definitely looks a lot better out of her power suit then she does in the power suit.
It's a good thing she can 'strip' off her suit when she needs to during battle.
Samus taking aim at Fox McCloud, and allowing all of us to take aim at her cute backside.
Other characters, like Wario, take a slightly different approach when showing us their backsides. Here Wario takes the opportunity to pass gas in our faces. And no one even had to pull his finger.
