The Comic Action Heroes were another attempt to captilize on the power of the SuperHeroes license. Unlike the Bendies and Supersofties of '74, the Comic Action Heroes sold well and lasted until 1978 when they were revamped. Neal Kublan mentions that Mego was the first to play with the concept of the 3 3/4" action figure. These early catalog shots show only a handful of completed figures which are obviously handpainted.
The playsets revolve around the "Comic Activator" device, an explosives plunger that looks straight out of Looney Tunes. Mego planned to market the Activator on it's own.
The "cartoony" nature of the line continues in the playsets, the Mangler is a device which flattens Supervillians. The "Fortress of Solitude" is an on model version of Alex Toths' "Hall of Justice" from the Superfriends but renamed to avoid confusion with the 8" Playset.
It's interesting to note that the Wonderwoman playset shows two towers but only come with one and that the Joker is filling in for the "yet to be made" Penguin.
