HEAVY DUTY grew up in Chicago and is a big city guy, heart and soul. He likes lots of noise, action, and people. His craving for the fast-paced life in the city is satisfied in two ways: hammering his way through huge COBRA forces with the biggest weaponry he can find, and playing classical music in large symphony halls. In OPERATION CHINA SHOP, he came up against a COBRA C.L.A.W.S. for the first time. The two fought each other with matching SRCDs (Short-Range Cannon Destroyers) until the COBRA C.L.A.W.S. was forced to retreat. But HEAVY DUTY knows that until COBRA is destroyed, he will be facing more COBRA C.L.A.W.S. and their heavy artillery again.
"The rich sounds of the violin and the explosion of anti-tank missiles are both music to my ears."
COBRA C.L.A.W.S. are COBRA's new elite troops. These lightly armored heavy weapons specialists can take a lot of punishment and dish out even more. With new lightweight, ionized fiber armor (developed from stolen US Army technology), they can move quickly into position with the latest weapons, to take out large targets–including G. I. JOE's vehicles. The grunts are all competing against each other to get into this new squad, but only the best and nastiest ones will be chosen. The COBRA C.L.A.W.S. want revenge against HEAVY DUTY because of the damage he did to their ranks when they were trying to take over a global satellite communications network.
"Our weapons are the best–we can squeeze the enemy into a corner or snap them in two with crushing firepower."
