MMZ Zero looks badass, just FABULOUSly badass. The whole series was based upon this concept.
The first concept drawings by Inti Creates were badass, but the end result which we got in the Zero Series are absolutly not my taste. He looks not like a battlehardened, manly soldier like Snake does, but more like a joke of a hero. The eyes arenīt sharpened, he has so much less hair.
I always liked the long Z-Saber in X4 and X5, but than the Z-Saber got shorter and more shorter. In ZX the ZX-Saber is only as long as a freaking knive! Why arenīt the guys from Inti Creates no Sephiroth lovers? We would have had an Z-Masamune.
