Sort of, but not quite. Shaider over there on the left was used for Ryan in season two, but the footage, for the most part, came from Metalder and Spielban, two completely seperate series. That's why they always got split up during an episode, because it would have been expensive to film original footage.
WoW! Oh my GOSH! It's like going back at the beginning of the 80's, when we were fixing the tv screen waiting for the "TRANSMUTATION!" (in the french version at least). Those are really superbe costume.
