Joe Rombie is a dark green skin Stickman with black eyes and mouth. Although there is nothing known about his nature when he was still human, he appears to have excessively violent behavior and due to such, having been injected during test experiments, feeling being tortured by MortoGen and turning him into super-soldier, seeking vengeance and going on a rampage to kill everyone who gets in his way. Joe Rombie doesn't talk at all, and he can also eat your brains.
