A big, bulky terminator. He is almost entirely mechanical and very powerful.  He doesn't look very human, although he has the same general physique (two legs, two arms).  As for the face, remember the emblem with the Punisher's skull.  He looks more like him, with a grid instead of a mouth and multifaceted rubies instead of eyes.  He's dressed in an ochre-bronze mechanic's robe, and most of his body is exposed, so you can see a fully mechanical body.  Terminator (Arnold Schwarzenegger) in steampunk style.
