Following the success of Voltron, Peter Keefe's World Events Productions imported the 1984 series, Star Musketeer Bismarck, from Japan, and repackaged it for US consumption as Saber Rider & the Star Sheriffs. Arriving as it did the same year as Filmation's final series, Bravestarr, some might think that, despite it being three years older, Saber Rider was a sort-of ripoff. It wasn't.
I never got to see the show, so there isn't going to be a rating. Let's serve up the first episode.
With the full face-covering helmets on the Star Sheriffs, I think you can see where the folks behind the Power Rangers got the idea for their costumes, and Saban, which imported the Rangers to the US, would duplicate it in mishandling Marvel's Avengers more than a decade later.
