Captain Caveman:
Debuting almost the same time as Charlie's Angels, Hanna Barbera came out with a new cartoon: Captain Caveman. He was a caveman frozen in ice and gets de-thawed in the mid-late 70's. Even though he was naked, he fought crime, with the help of his three "Teen Angels". I don't remember the gals that well, except I believe the blonde was an airhead (for some reason on TV the blondes are always the airheads)...
