Heavy Metal didn't join the Army to become a tank driver. He signed up so he could go to Finance School. That section of Brooklyn he grew up in is home to America's poverty-stricken. Just reaching middle-class is like becoming a billionaire. In many other ways, he is like his teammate Bazooka. He's smart and practical and found something during his enlistment that changes his life. While Bazooka thought a rocket-propelled grenade is a perfect weapon, Heavy Metal found joy in driving tanks.

Heavy Metal was one of a group of prospective Joes who were tested in the Nevada desert by Lady Jaye. During the course of the test the group came under attack from Cobra. Later when stationed at the Pit Heavy Metal worked in the motor pool when he was one of the Joes who greeted the newly arrived Sgt. Slaughter. Not having been told of any new arrivals, Heavy Metal and Clutch decided to poke Slaughter's bag. They soon learnt this was a mistake. Heavy Metal subsequently participated in other missions, including the assault on Springfield. Back at the Pit he was part of a team unsuccessfully sent to recapture the escaping Zartan. Not long afterwards Hawk announced the grim news that the G.I. Joe team was being shut down and Heavy Metal was temporarily quartered up in Fort Wadsworth.
Heavy Metal was one of the tragic casualties in the infamous Trucial Abysmia conflict. He bravely sacrificed himself by jumping in front of Breaker and Quick Kick and shielding them from a S.A.W.-Viper's hail of gunfire.

Heavy Metal's real name was "Steve". When he was at school he told on two pupils who cheated at a maths test so they beat him up. But another pupil called Tony Lander stopped them, saying "Look upon it as a personal favour you owe me, Steve."
Heavy Metal was initially part of a group of prospective new Action Force members tested by Lady Jaye. Subsequently he assigned to the European branch of Action Force and was in charge of the Mauler M.B.T.s. When testing one at Salisbury Plain he came under attack from Cobra F.A.N.G.s but destroyed them.
Heavy Metal was shocked when he learned that Tony Lander had become a Cobra Trooper who went rogue and stole a canister of lethal nerve gas, threatening to release it into the atmosphere. He confronted Lander on the roof of a warehouse and tried to talk his old friend out of it but could not. Heavy Metal found himself aiming his gun at Lander and saying he would use it if he had to. Suddenly Lander was shot dead by the newly arrived Destro, who claimed to have done Heavy Metal a favour but the latter was not convinced.
When the Decepticon Megatron rampaged through London, Heavy Metal led a squad of Maulers to attack but they were unsuccessful. He subsequently participated in missions in the Americas. He was also part of a squad who liberated an oil terminal in the Gulf of Arabia from Cobra.
