A former U.S. Marine, serving several tours of Iraq and Afghanistan. On a recon trip on his last tour in Afghanistan, he is separated from his group. He falls into a sinkhole that reveals a hidden cave and temple. The temple is Cyttorak. Reading an inscription and touching a gem in the cave turns Cain into the Juggernaut. He spends the next several years of his life battling heroes and villains alike on the side of good and evil. At a certain point he just becomes tired of it all. He decides to retire into the mountains. His actions anger Cyttorak, which punishes him by sapping his strength. He constantly fights against the gem’s urge to destroy.
