13. Fatman, Metal Gear Solid 2: Sons of Liberty (2001)

Named after the A-bomb that leveled Nagasaki in World War II, Fatman makes this list not because of his sheer physical size, but because of his shrewd layering: a bomb blast suit, ballistic inserts, and a explosion protector plate. And, yes, we're overlooking his manicures that often showed him sporting pink fingernails; that's just for when he's out with the girls...or slaying fools at off-shore decontamination facilities.
