The 1980 Superhero offerings saw a decline in the 8" assortment and a renewed focus on 12" Heroes.
The Elastic Heroes carried on and now included TV newcomer Plastic Man. The Elastic Heroes were filled with corn syrup at Mego's Long Island headquarters and were a nightmare, actually causing them to have rats.
The 15" Growling Hulk is neat unproduced item, probably not produced as the Hulk TV series was entering it's final stretch.
