In 1985, every figure from back to the beginning of the line was being offered except Zodac, Faker... and Ram Man. That suggests the most common figures you found were the ones no one wanted to keep, rather than highest production runs.
I know my extensive vintage collection included a Zodac complete with his "apron" and handgun. Either I got lucky at a yard sale or was gifted when MotU was dying on the pegs at $2.99 each a Zodac that had been sitting unwanted since at least the '84 holiday season.
