figures were based on the "Mazinger Z" animated
series from Japan, which aired in the US as "Force
Five". They were made by Bandai and sold by Mattel.
Some of these figures had 2nd and 3rd versions with minor
repaints, weapon changes and minor mold variations (the
2nd and 3rd versions are not as valuable). Many other figures
were released by Popy in Japan throughout the 70's and 80's.
There was also a Marvel comic series based on this line.
