There are two variations of the Karza figure, most notably with the head sculpt. The Japan version has a smaller mouth, and the eyes are more slanted and brighter red, and is mostly hollowed out, stamped on the underside of the foot, it reads "made in Japan". The Hong Kong version has a larger mouth, and more triangular shaped eyes which are a darker red, and the head is mostly solid plastic, and the stamp on the figures back reads "made in Hong Kong". Apart from this the figures are identical and as evil as can be.
