OMAC actually stands for One Man Army Corps, but to me he's just One More Awesome Character created by Jack Kirby. Really, you can't go wrong with a superhero who wears a mohawk and sideburns!
I penciled this one during an afternoon as a warmup, put it in a drawer, then pulled it out and inked it one evening when I had some spare time. As you might tell, I was doing my best to unleash my "inner Kirby" while working on it. And since I don't work much in full colour anymore, I thought it might be fun to take a crack at colouring it and adding some tones in photoshop. As with a lot of my recent posts, you can see the original pencil drawing for it below.
