That sounds like you're saying that Kakuzu didn't have all 5 elements on him at any time(which at one point in his life might've been the case).

But you'd have to think that he would've thought having 5 different elemental hearts on his being at all times was a little more advantageous then going around looking for them like they were pokemon right?
