When anybody mentions Monster Squad the squad that appears in my mind is from 1976. The Monster Squad is a television series produced by D’Angelo-Bullock-Allen Productions that aired Saturday mornings on NBC from September 11, 1976, to September 3, 1977. This Saturday Morning program was my jam.
Via Wikipedia: The monsters, wanting to make up for the misdeeds of their pasts, became superhero crimefighters who used their unique abilities to challenge and defeat various supervillains. In most episodes, Walt would send the monsters out to investigate crimes and fight the villains while monitoring the activities from the wax museum via the Crime Computer, presumably because his job required him to be at the wax museum at all times. However, Walt would sometimes join the climactic battle with his comrades in some episodes and come to the rescue when needed.
