As is the case with his previous series, "Urutora Q"
(1965), series creator Eiji Tsuburaya
uses and redecorates famous Toho monsters for the show. Baragon (from Frankenstein Conquers the World
(1965)), who was also used in aforementioned series (as the monster Pagos), was used as monsters Neronga in Episode 3 ("Sally Forth, Science Patrol!") and Gabora in Episode 9 ("Operation Lightining Speed"). And the King of the Monsters himself, Godzilla (who was also used as the monster Gomess in the first episode of Q), was used as the frillnecked lizard monster Jirass in Episode 10 ("The Mysterious Dinosaur Base"). Using the body of the "Mosu-Goji" suit and the head of the "Daisensô-Goji" suit, Godzilla/Jirass was fitted with a frill collar around his neck, as well as a minor paint job. This was because the script called for a lizard monster, so Eiji said, "Okay, then, let's use a Godzilla suit!"See more
