As we mentioned back on 2/28, The Black Series 6-Inch 79: Dryden Vos figure had a color change feature that reveals red veins in his face, when cold. It was also mentioned by a few of our readers today that the blade edges of his Kyuzo Petars weapons changed as well, so I put him back in the freezer with his weapons and the blade edges did turn red. Its not as noticeable as his face, but they did change. Above is a quick photo.
I am just finishing up all of the Dryden Vos pictures and will get them up soon.
