Imported from Japan. The secret base and science lab utilized by Doctor Genzo Umon from UFO Robot Grendizer is recreated with this new figure. Duke Fleed and his robot Grendizer operated from the secret base inside a dam and by using different escape routes he could confound the enemy. The main (and most famous) exit is the one modeled in this playset. The small ejectable Spaizer spacecraft is made of plastic, while the main base is die-cast. Window box packaging.
