A mention of this guy in one of Benton's threads prompted me to do skope I've been thinking about for a while. Of course, I'm old enough to remember this guy from way back in the 70's when my brother started collecting Nova. So, here's Diamondhead. He's done on GGX_Martinex_Gren with some added pieces by Renegade and Tommyboy along with a little Blender magic by me to get the head right.

I've uploaded him to my Yahoo group (link in my signature).
Great job Hoss. I am currently collecting Nova myself and i think it was nova that introduced the character. I will definitely search for the issue. Incredible job man.
Look for issue #3 (way back in 1976, I believe). He makes a few appearances along with Powerhouse and Condor in the first dozen issues or so.
