In 1986, Saban Entertainment combined footage from GoShogun and Akū Dai Sakusen Srungle (Great Military Operation in Subspace Srungle or Mission Outer Space Srungle), a similar show produced by Kokusai Eiga-sha, to form Macron 1. In the US version, test pilot David Chance is accidentally transported into a parallel universe controlled by a tyrannical organization called GRIP, led by Dark Star. This allows GRIP to send their forces to Earth, leaving Dark Star's cyborg henchman Orn as deputy in the alternate universe. Fighting against GRIP are two teams comprising "Macron 1": the first (from the GoShogun footage) battles against Dark Star's legions on Earth; Beta Command (from the Srungle footage) is working to overthrow Orn. The main focus is on the Macron team on Earth, with Beta Command appearing sporadically.
