Storyline
A scourge is sweeping across the galaxy—a scourge called the Blasters! These devious and handily-numbered alien invaders conquer, devour, and destroy every civilized world they see—and now, their sights are set on Earth! But worry not, good children, because Earth has a top-secret countermeasure developed by Dr. Hoshi and the International Science Police Headquarters. Our secret weapon is the mighty, towering super robot, Astroganger! Crafted from mysterious alien living metal, the robot Ganger has just one weakness—he's kinda dumb! Enter the best person for the job, Dr. Hoshi's ten-year-old son Kantaro. By joining their powers together, Ganger and Kantaro fuse the incredible power of a fightin', flyin' robot with the uncompromisingly savage, decisive intelligence of a middle schooler: Astroganger! With their powers combined, they'll save the world approximately twenty-six times! (Source: Discotek Media)
