Heavy Duty

From Joepedia - The G.I. Joe Wiki

Several iterations of Heavy Duty have existed in different G.I. Joe series:

• Heavy Duty - the original heavy ordnance expert from the A Real American Hero series.
• Heavy Duty - the musclebounded macho man from the Sigma 6 series.
• Heavy Duty - the heavy weapons specialist appearing in the upcoming film

However, he shouldn't be confused with:

• Heavy Duty - the code name now used by the character we used to know as Roadblock and appearing in the comics continuity by IDW Publishing.
