Sei Juushi Bismarck (星銃士ビスマルク Sei Jūshi Bisumaruku), also known as Star Musketeer Bismarck or simply Bismark, is an 80s Japanese science fiction and mecha TV anime created by Studio Pierrot.
The series aired on Nippon Television from October 7, 1984 to September 25, 1985, totaling 51 episodes.
In 1986, the rights to Bismark were sold to the United States company World Events Productions (WEP). WEP reorganized and rewrote the series, incorporating both original episodes and creating six new ones before releasing it in 1987 under the name Saber Rider and the Star Sheriffs.
