Kinda hard not to think of Sgt. Rock when you think about Joe Kuburt and I was intentionally going to try to steer away from Rock until Ben shared the link to this article. If you scroll down a bit you come to what seems to be the genesis of Sgt. Rock, The Rock! A story of a once professional prize fighter who wasn't known so much for his winning record as he was known for his tenacity. "They called him -- "The human obstacle course"! You had to beat him -- to be someone! But no one had ever made him stay down! Now -- he was fighting in a different kind of ring! Would he still be -- THE ROCK!" How can you not want to draw this guy?! What a great character!
