Saber Rider and the Star Sheriffs is an animated television space western, similar to the series The Adventures of the Galaxy Rangers and BraveStarr. The series premiered in the United States in 1987 and had a run of 52 episodes. The show was based on Star Musketeer Bismarck, a Japanese anime series created by Studio Pierrot that achieved moderate success in Japan. The English language rights to the series was purchased by World Events Productions, the same company behind the English-language version of Voltron, in 1986. WEP reorganized and rewrote the series, incorporating the original episodes and creating 6 new ones, before releasing it under the name Saber Rider and the Star Sheriffs.
Saber Rider recalls how he, April, Colt and Fireball met and became the dynamic frontier fighting team: Saber Rider and the Star Sheriffs. Saber Rider arrives on Planet Yuma for his assignment to the special project, Ramrod, which is being led by April. He discovers that the Outrider, Vanquo, is plotting to undermine Ramrod, and, with the help of Fireball and Colt, who are on Yuma pursuing their own interests, Saber Rider defeats the Outriders and their gigantic battle machine, Renegade. With April's encouragement, the group decides to stay together to help tame the new frontier.
When the Star Sheriffs arrive to investigate a destroyed Cavalry Command base, they are attacked by Outriders. One of the Star Sheriffs must go on a maverick mission to defeat them. Using a trick coin, Colt wins the toss against Saber Rider and flies off to battle the enemy, who trap him in a canyon. But, help comes from an unlikely source: a little iguana that Colt has befriended. With the iguana's help, Colt escapes and joins the other Star Sheriffs in defeating the Outriders.
