Godzilla vs. Megalon

Scientist Goro, with nephew Rokuro and buddy Hiroshi (Katsuhiko Sasaki, Hiroyuki Kawase, Yukata Hayashi) are puzzling over the burglars who escaped when they arrived at his extra-mod home, analyzing a button they grabbed, noting progress on the robot, and getting some Easter Island dates way wrong, in Godzilla Vs. Megalon, 1973.

We’re suddenly inside subterranean Seatopia (probably beneath Easter Island) where the boss guy (Robert Dunham) has gotten the green light from agents on earth to loose the (title) monster they’ve been keeping stashed, after nuclear tests messed up their kingdom, in Godzilla Vs. Megalon, 1973.

The enemies from undersea have gotten Gigan (with the spines) to team up with Megalon to clobber the not too clever and just now up-sized good guy robot Jet Jaguar, created by Goro (Katsuhiko Sasaki, observing with friends Hiroyuki Kawase and Yukata Hayashi ), when the friendly champion arrives, to maybe save the day, in Godzilla Vs. Megalon, 1973.

Opening the 13th feature in the Toho Films Ltd. franchise, made on a tighter schedule and budget, with narration referring to the actual American Cannikin nuclear test, the hero is aroused, and trouble for his cohabitants Rodan and Anguirus who fall into some kind of crack, in Godzilla Vs. Megalon, 1973.
