Sgt. Rock action figure
I don't remember seeing these figures in the store. I wouldn't have noticed them anyway sitting beside G.I. Joe figures and vehicles. A description from www.virtualtoychest.com
With the exception of Sgt. Rock himself, most the action figures were released under generic names as simply "Marine", "Ranger", and "Medic". The recurring characters from Sgt. Rock's Easy Company in D.C. Comics did not appear. Rock himself differed somewhat from his usual comic book attire, where he was often drawn wearing a short-sleeved or sleeveless shirt and ammo belts, the action figure wore a long-sleeved shirt and no ammo belts.
Despite the fact the Sgt. Rock comic took place during World War 2, Remco including noticeable post-war items. Among them were M-16 assault rifles and helicopter gunships.
In the comic books, Sgt. Rock usually fought the Axis powers, primarily the Germans. For whatever reasons, Remco chose to create a new enemy for the toy series. Sold on their own packaging as "The Bad Guys: the Ultimate Enemy", Remco's packaging pitched them as foes of Sgt. Rock, G.I. Joe, M.A.S.H. (who were non-combatants!) and "all mini action soldiers". The toys were almost entirely recolored Sgt. Rock products, but did not include kid-scale dog tags. The Bad Guys' logo featured a black and yellow cobra snake, an obvious attempt to connect to G.I.JOE: A Real American Hero's arch-enemy Cobra.
