This show was originally titled "Star Musketeer Bismarck" when released in Japan. World Event Productions purchased the rights and rewrote the show, using much of the original material, and it became the popular space-western Saber Rider and the Star Sheriffs. The good guys used their robotic transportation to transform into a gigantic robot named Ramrod whenever they had to take on a Desperado unit, another type of large robot. Saber Rider is the leader of the brave Star Sheriffs, including Colt, April, Fireball and Commander Eagle. The Saber Riders protect the planetary pioneers from the Outriders. The Outriders are strange spirit/gas-like beings from space.
