I often think about how the ball buster in God Hand doesn’t affect female enemies. One of the weird explanations my brain has proffered is that the move only hits at a certain range relative to the base of a person’s pelvis. So although it would be extremely painful to be kicked in any external genitalia, female enemy genitalia (on average) doesn’t extend far enough away from the body to be hit by the move. But then actual genitalia (of any person) can drastically differ in how far it extends from the body. This leads me to the conclusion that God Hand imperfectly simulates genitalia.
I guess an alternative explanation is that a necessary prerequisite of the move is that it makes contact with a ‘ball’ or ‘balls’. So even if it physically hits an opponent, it has no effect unless it contacts a gonad.
An anagram of ‘God Hand’ is ‘Gonad HD’.
