The Fandom Post is reporting that RetroCrush has added the GoShogun anime film to Amazon Prime. The film is available in its English dubbed version.

The story of GoShogun is described as:

A meteor strikes the Earth and is found to emanate a powerful new energy called Beamler, which is used to power a battle robot, GoShogun, and a teleporting fortress, Good Thunder. The Docougar Crime Syndicate, led by crime lord Neo Neros, tries to steal the secret of the energy from the inventor of GoShogun, but he kills himself rather than let them acquire it. His son is targeted by Neo Neros next, but he is taken in by the crew aboard Good Thunder, who travel the world fighting Neo Neros’s forces with GoShogun.
