''Sei Juushi Bismarck'' is the story of four space explorers stationed on Ganymede, a moon of Jupiter. Their goal is to protect our solar system from the Deathcula imperium.

Although not as popular as ''Anime/SaberRiderAndTheStarSheriffs'', an Americanized (and arguably {{Macekre}}d) dub produced by Creator/WorldEventsProductions, it is more sophisticated--and unlike ''Saber Rider'', it ''does'' have action figure toys in its own country.
