Toei really had no idea what to do with a sequel to GoRanger, and went a bit more serious with this one, at least at first. after the ratings weren't as good, they added Banba Sokichi, AKA Big One (as portrayed by the legendary Hiroshi Miyauchi).
this was the only show that ended in both a team up and a movie.
apparently I've written about this show before. how funny I didn't remember it!
