ShodaiGigan

The ShodaiGigan (初代ガイガン, ShodaiGaigan) is the Gigan suit used in the 1972 and 1973 Godzilla films, Godzilla vs. Gigan and Godzilla vs. Megalon, as well as the 1973 television series, Zone Fighter.

Name
The ShodaiGigan's name comes from shodai (初代), meaning first generation, and Gigan, which comes from Gigan's name.

Detail
This suit has darkish green skin, with King Ghidorah-like golden scales that cover this suit's body, neck and tail. The suit's fin-like spines are also a golden color, but are smooth and not scaled. In Godzilla vs. Megalon, the suit was made thinner, less bulky, the horn on the head was less pointed, and the buzzsaw didn't move, since it was made of static pieces. This suit also had different sized back fins, a more sad eye visor, scales running up the back/sides of the neck and longer legs compared to the original version. This suit is also called the MegaroGigan.
