Willie serves as the indispensable demolitions expert within Koko's armed outfit, his expertise forged through intense combat and explosive ordnance experience during the Gulf War. Off the battlefield, he carries himself with a refined, gentlemanly demeanor—even taking on the role of academic tutor to the young protagonist Jonah. Yet the moment a mission calls for detonations, a near-obsessive passion ignites within him, and he delivers devastatingly precise explosive support that the entire team relies upon.
