He's a gourmet cook who can wield his hand-ground, carbon-steel cook's knife and his M2 .50 caliber "Ma Deuce" Browning heavy machine gun with equal skill. He wanted to be a chef and attend the Escoffier School in France, when a recruiter signed him up with the promise that the army would train him to be a cook. He later joined the G.I. Joe team, where, on any given day, he can whip up haute cuisine for the team - and mince anything in his path with a barrage of gunfire. Cobra gives him plenty of opportunity to perfect his skill with the Browning, as the evil organization spreads its vile presence from the snowy north to the town of Springfield.
Say, you look familiar...
This character doesn't have much of an established backstory. Unless contradicted by a canon source, you can assume their history mostly mirrors Roadblock (RAH)'s.
