Message from Space: Galactic Wars 

Centuries after the people of Earth master interstellar travel, humanity is thriving across the galaxy. But this all changes when the Gavanas Empire arrives, as the merciless despot Roxair XIII quickly conquers the 15th Solar System and enslaves all life there to his cause! This early TV live action space opera was conceived by superhero giant Shotaro Ishinomori (Kamen Rider) and stars LOST's Hiroyuki Sanada in one of his first roles!
