Tōshō Daimos the movie is a side story based on the same mythology established in the anime TV series about a powerful super robot, Daimos and its pilot, Kazuya Ryūzaki. In this movie, the Baam send their giant robot Zeron to battle Daimos.

This update of the 1950 western TV series changes Cisco and Pancho from wandering heroes of the old west to somewhat anti-"gringo" Mexican revolutionaries.
